I. Abstract
Background and Significance- The patient safety and quality of care movement of the
past decade has advanced to include and be somewhat dependent on new information
technologies in the form of electronic health r~cords. The healthcare policy environment
has both quality and information technology tied very tightly together in an effort not
only to improve healthcare quality, but also to save money. In order to achieve these
goals, a better understanding ofhow clinical staff utilizes technology is necessary as it
relates to electronic health record investment success. The present research study aims to
measure technology end users' past electronic health record objective use in conjunction
with their subjective feelings towards past and future teclmologies in order to better
understand how to predict future system utilization. This study is being performed in
order to 1) Test the relevance of expanding the cutTent IT theory based TAM to include
objective historical use data, to more fully explain the variance in actual technology use;
2) To provide an expanded framework for future application use models of this nature;
and 3) To serve as a quality improvement collection tool, utilizing narrative feedback
from study patiicipants to identify organizational attributes that positively or negatively
impact actual performance when utilizing an information technology (IT).
Literature Review- A comprehensive literature review was performed in the following
areas: 1) Quality of care and patient safety from a healthcm·e policy perspective; 2)
Information technology theories that have been applied to the healthcare setting; and 3)
2
An integrated review of performance measures as it relates to information technology in
neonatal intensive care units (NICUs).
Conceptual Models- The study utilizes the core conceptual model of TAM (see Figure
1), described as a measure of end user technology acceptance through two subjective
variables, perceived usefulness and perceived ease of use. The study measures the
acceptance of an electronic health record technology, Cribnotes, through the perspective
ofNICU nursing staff by measuring not only the traditional TAM subjective variables of
perceived ease of use and perceived usefulness by individual nurses, but also utilizing
objective performance data of the same nurses on a past information technology,
Medication Administration Checking (MAK). Additional independent variables of
nursing staff measured will be age, gender, race, professional degree, andjob title.
Lastly, actual system use of the Cribnotes technology will serve as the dependent variable
and will be measured by objective performance data.
Hypothesis and/or research questions- HI: The MAK objective nursing performance
score will be the primary predictor, or will have the most impact, on the Cribnotes
objective nursing performance score when compared individually with all other
independent variables. H2: The MAK objective nursing performance score will be the
primary predictor, or will have the most impact, on the Cribnotes objective nursing
performance score when compared with all other independent variables in aggregate; H3:
The MAK objective nursing performance score will work in conjunction with RN
behavioral intentions to create a more explanatory framework; and H4: The full model
3
consisting ofMAK objective nursing performance score and the pre-implementation
subjective RN behavioral intentions will explain all the variation in the dependent
variable, Cribnotes objective performance score. Research questions include: 1) Will RN
historic system perfonnance be a better predictor of future system use than utilizing their
attitude, or behavioral intention to use it? 2) Will RN historic system performance work
in conjunction with RN behavioral intentions to explain more R squared variability
together, rather than independently? 3) Were clinical, social, and/or technical factors
identified that can be added as subjective variables to enhance future analysis ofR
squared findings related to RN performance?
Methods and Materials- The study takes place at the University of South Alabama's
Children's and Women's Hospital in the NICU Department. The sample size is 69 nurses
and the. duration of the study is a 24 months of software utilization timeframes. The basic
research design revolves around the development and testing of a healthcare information
technology prediction model framework. This prediction model framework is based on
the traditional TAM with the enhancement of an added core variable portraying historic
objective use of an information system. The objective use data is measured in terms of
nursing performance on an individual basis when quality checks specific to breast milk
are performed prior to administration to neonates. In addition, pre-post survey data was
collected from the nurse participants related to their attitudes, or intentional behaviors,
towards information teclmology of the past, present, and future. The surveys are directly
linked to the traditional TAM with four survey questions specific to their perceived ease
of use and perceived usefulness of two information teclmologies, MAK and Cribnotes.
4
Multiple regression analysis was conducted in order to explain different combinations of
outcome variability related to future use of the Cribnotes system.
Results and Discussion- The Quantitative regression analysis results show that the full
model is statistically significant (p<.05) and explains on a very conservative level 14.7%
of the variation in the Cribnotes performance score. Related to the individual coefficients,
the objective measure of performance scores on the old system (MAK) is significantly .
positively related to the performance scores on the new system (Cribnotes) (p < 0.05).
Similarly, the pre-implementation survey-based subjective measure result for Pre
Cribnotes Ease of Use is also significantly positively related to the performance scores on
the new system (p<.05). The qualitative content analysis reveals two negative high level
categories represented by Overall Clinical Impact (Negative) and Overall IT Impact
(Negative) that suggest unexplained variability may be due to a combination of clinical
workflow and IT Infrastructure concerns. Based on these findings, a new model
framework was proposed.
Conclusion- Hypotheses 1, 2, and 3 were accepted because the addition ofthe objective
performance score measurement was the most powerful of all the variables. It also
worked in combination with subjective variables to enhance the TAM. Hypothesis 4 was
rejected due to the remaining variability left unexplained by the full model. All research
questions echoed Hypotheses 1-3 and were thus affirmed.

II. Background and Significance
For more than a decade, the theme of improved patient safety and quality of care in the
United States healthcare system has been a common thread in healthcare policy decision
making and overall strategy. Specifically, the on-going push for the implementation and
meaningful use of electronic health records (EHR) seems to be gaining more ground than
ever and is strongly supported by the federal government. EHRs as a fundamental
component in the patient safety and quality of care movement will not only provide an
electronic medium for what in the past was a paper based system, but has the potential to
fundamentally change the workflows and practices of clinical end users. For these
reasons, the importance of understanding how to become successful users of teclmology
across the healthcare spectrum has never been greater.
The present research study aims to measure technology end users' past electronic health
record objective use in conjunction with their subjective feelings towards past and future
technologies in order better understand how to predict future system utilization. It is
significant in that it applies and expands upon an Information Systems Theory, the
Technology Acceptance Model (TAM) (Davis, 1989), to an academic teaching hospital
based Neo-natal Intensive Care Unit (NICU). The NICU is located in the Southeast
region ofthe United States at the University of South Alabama Children's and Women's
Hospital. This NICU is considered large due to its regional presence and because it
averages seventy-five neonates daily. NICUs are by nature complex and as the research
literature suggests, it is very impmiant to understand how users adopt a new technology
in order to be successful (Rikli, 2009). This study was performed in order to model the
6
relevance of expanding the cun·ent IT theory based TAM to include objective historical
use data, to more fully explain the variance in actual technology use. This study is not
intended to be directly used across other departments within USA Hospitals or at other
institutions, but rather to provide an expanded framework for future application use
models of this nature. In addition, this study will serve as a quality improvement
collection tool, utilizing narrative feedback from study participants to identify
organizational attributes that positively or negatively impact actual performance when
utilizing an information technology (IT). The research questions are as follows: 1) Will
RN historic system performance be a better predictor of future system use than utilizing
their attitude, or behavioral intention to use it? 2) Will RN historic system performance
work in conjunction with RN behavioral intentions to explain more R squared variability
together, rather than independently? 3) Were clinical, social, and/or technical factors
identified that can be added as subjective variables to enhance future analysis ofR
squared findings related to RN performance? The study sample consists of an estimated
one hundred nursing participants. Participants were administered surveys to gain an
understanding of their attitudes, or behavioral intentions, towards use of both the MAK
and Cribnotes information systems. Pruiicipant data specific to how well they used the
information systems was measured in terms of perfonnru1ce quality checks that occur
before administering breast milk to neonates. This data was gathered via system
utilization reports spanning a consecutive eighteen month period oftime for the MAK
system, followed by a 6 month period of time for the Cribnotes system.
7
This study first draws from the literature the linkages between healthcare quality
initiatives, information systems, and associated financial implications. In so doing, a
number of information systems theories will be reviewed with the TAM being selected
and directly applied to the framework for this study. A frniher in depth review of TAM is
then conducted as it relates to the theory. In addition, a review ofNICU teclmology
performance studies related to clinical outcome and end users are reviewed. Next,
conceptual models ofT AM, study variables and interventions are developed and
explained. The methodology comprising the study design is then addressed by defining
the setting, sample, data sources, intervention, scoring calculations, and associated data
elements. The analytical approach is that of a model based on past experience where
quantitative regression analysis will be conducted using different combinations of the
variables to explain the different levels of variability related to use of the Cribnotes
system. In addition, qualitative based surveys will be analyzed and content analysis will
be performed to interpret the impact of nursing behavioral intentions related to Cribnotes.
III. Literature Review
The approach to this comprehensive literature review encompasses a review of health care
policy in the areas of patient safety and quality care, then reviews theories related to
teclmology in healthcare, and lastly, identifies themes and trends discovered as a result of
an integrated review of varying types ofEHR performance literature specific to NICUs.
Healthcare Policy- Patient safety and quality momentum over the past decade
In 1999, the repmi, "To Err is Human: Building a safer healthcare system" was released
by the Institute of Medicine (IOM) providing insight into the deep rooted patient safety
8
concerns facing the US health care system. The report describes common problems that
occur in healthcare everyday including but not limited to adverse drug events, improper
transfusions, surgical injuries, wrong-site surgery, restraint-related injuries, falls, burns,
pressure ulcers, mistaken patient identities, suicide, and death (Kohn, 1999). Further, the
report identifies that intensive care units (ICUs), operating rooms, and emergency
departments are locations within healthcare delivery systems that are most prone to high
error rates with dire consequences (Kohn, 1999). Other components of the repmi that
have great bearing are the resulting quantified costs in terms of monetary and human
lives. At the time of publication of this repmi, the nationwide costs of preventable
medical errors were estimated to be between $1 7 billion and $29 billion per year in
hospitals across the United States, and a staggering number between 44,000 and 98,000
deaths (Kohn, 1999).
While patients and practitioners alike were still digesting the IOM report, business
owners took notice of one recommendation from the report that urged large employers to
provide more market reinforcement for the quality and safety of health care. SpUITed by
the patient safety quality movement initiated by the IOM's 1999 report, the Leapfrog
Group was organized in fall of 2000 by a constituency of large employers with suppmi
from the Business Roundtable (BRT) (The Leapfrog Group, 2011). The primary goal was
to create a rewards system built aroUI1d improvements related to safety and quality for
hospitals. The Leapfrog Group measures and rates hospitals on best practices, in
accordance with the National Quality Forum (The Leapfrog Group, 2011). If a hospital
follows these best practices related to patient safety, overall ris!< to the patient, provider,
9
and the institution should decrease in the care environment. Lastly, the Leapfrog Group
takes the consumer point of view when determining how to approach organizational
standards directly related to patient safety. US Hospitals are not mandated by any Federal
or State laws to participate with the Leapfrog Group and compliance with the standards
are on a voluntary reporting basis (The Leapfrog Group, 2011).
In the spring of 2001, IOM published "Crossing the quality chasm- a new healthcare
system for the 21st century." The report's recommendations call on Healthcare
Organizations (HCOs) to take a hard look at their processes of care delivery and adjust
them as necessary to work in conjunction with information teclmologies. In addition, an
overall leadership review from a managerial and clinical perspective is recommended in
the rep01t. More specifically, the development of efficient and effective teams who will
better manage clinical knowledge and skill-sets, and coordinate care across patient
conditions, services, and settings over time was recommended (Institute of Medicine-
Committee on Quality of Health Care in America, 2001). Lastly, an improved checks and
balance system was recommended to instill performance based outcome measurements
for purposes of greater accountability and overall improvement (Institute of Medicine-,..
Cmrunittee on Quality of Health Care in America, 2001).
As the patient safety and information technology charge continued to grow over the next
two years, so too did the importance of protecting health information. As it relates to
safeguarding protected patients' healthcare ·information, the Health Insurance Pmtability
and Accountability Act compliance deadlines for the Privacy portion were instituted in
10
2003 (Department of Health and Hmnan Services- Office of the Secretary, 2003). In
addition, President Bush's State of the Union address places the healthcare quality
conundrum as the second most important goal of his administration. The focus is
broadened in that high quality of care is one aspect, but the goal also encompasses access
and affordability for the American people (President George W. Bush, 2003). That is too
say, showing the importance of quality in a manner greater than clinical outcomes, and
delving into core issues such as access and affordability of healthcare for all Americans.
This shows the President's agenda is truly focused on improving quality of care for those
being treated in the US healthcare system today, as well as, those who are not able to be
treated appropriately.
Once again, making a consistent stand on patient safety, President Bush's State of the
Union address in 2004, echoes that of2003, but is more focused on the computerization
ofhealthcare data and operations to play a key role in improving healthcare with
reductions in both medical mistakes and costs (President George W. Bush, 2004).
Following President Bush's statements and goals, the IOM published another article in
2004 titled, "Patient Safety: Achieving a New Standard for Care" (Aspden, 2004). This
report further stresses the importance of IT in contributing to the improvement of patient
safety and sets the stage for standards related to the development of a national health
information infrastructure (NHII). The need for the inception of the NHII was described
as critical for specifically addressing quality of care related patient safety problems
(Hjmi, 2005). President Bush then made an aggressive move by signing an executive
order requiring the Department of Health and Hmnan Services (HHS) to lead the charge
11
to advance the American people closer to obtaining secme access to EHRs by the year
2014. President Bush also called for the adoption ofhealthcare information teclmology
(HIT) interoperability standards and improved quality measures across internal Federal
Agencies such as HHS, the Depmiment of Defense (DOD), the Depm·tment of Veterans
Health Affairs (VHA) and the Office of Personnel Management (OPM) (American
College of Emergency Physicians, 2011). Lastly, President Bush also called for the
creation of the Office ofthe National Coordinator for Health Infmmation Teclmology
(ONCHIT) at the Federal level. Executive Order 13335 essentially demanded a strategic
plan at the national level within a ninety-day timeframe that would lay out a course of
action for public and private sector implementations of HIT (Department ofHealth and
Human Services- Office of the National Coordinator for Health Information Technology
(ONCHIT), 2004).
From President Bush's 2005 State of the Union Address, he once again urges the nation
that the use infmmation technology is key to preventing medical enors. He also likens
this to cost savings in not only the quality improvement arena, but also points tci a
comprehensive health care agenda and medical liabilities reform (President George W.
Bush, 2005). Also, in 2005, The Patient Safety and Quality Improvement Act of2005
pointed to teclmology as a catalyst for healthcare process improvement. Data collection,
analysis, and dissemination would be carried out by newly created Patient Safety
Organizations (Chuo, 2008) .. In the spring of2005, The Department of Health and Human
Services (HHS) released final HIP AA Security regulations that becan1e mandatory on
April20, 2005 and required healthcare providers to implement administrative, physical
12
and technical practices to protect the security of individually identifiable health
information that is electronically maintained or transmitted (Department of Health and
Human Services- Office ofthe Secretary, 2003).
In 2006, President Bush addresses patient safety once again in his State of the Union
speech, stating, "We will make wider use of electronic records and other health
information technology, to help control costs and reduce dangerous medical errors"
(President George W. Bush, 2006).
Again, and for the fifth consecutive year in a row, President Bush's State of the Union
Address in 2007 impresses upon the nation his patient safety goals. He once again ties the
need for improved information teclmology directly to medical enor and cost reductions
within the US healthcare system (President George W. Bush, 2007).
In 2009, the Obama administration further pushes the agenda by subsequently signing
into law The Health Information Technology for Economic and Clinical Health Act
(HITECH) within the larger American Recovery and Reinvestment Act of 2009 (ARRA)
(President Barrack Obama, 2009). The HITECH ACT is a federal attempt to infuse
billions of reimbursement dollars in the form of incentives to eligible providers and
hospitals if they adopt and use certified technology in a meaningful way. The Medicare
and Medicaid incentive programs for electronic health records are thus being driven by
"meaningful use". The Centers for Medicare and Medicaid Services (CMS) defines
meaningful use as a three stage approach where EHRs are used as an integral component
of a larger information technology infrastructure necessary to improve patient safety and
overall quality ofhealthcare (CMS Office of Public Affairs, 2010). The first stage of
13
meaningful use is to essentially collect electronic healthcare information in a
standardized way in order to better trend clinical conditions, coordinate patient care, and
begin repmiing clinical quality measures at both the local and public health levels (CMS
Office of Public Affairs, 2010). The stage one criteria proposes that eligible providers
completing twenty five objectives, fifteen of which are core, and eligible hospitals
completing twenty four objectives, fomieen of which are core. The second stage of
meaningful use is focused on expanding and building upon stage one quality criteria by
\ improving management of diseases, medications, clinical decision support, and care
transitions at the local level, while also further integrating at a state level through the
exchange of infonnation with public health agencies (CMS Office of Public Affairs,
201 0). The third stage is postured to begin seeing results for meaningful system use in
terms of efficiencies and effectiveness represented by patient safety, and overall quality
improvements at the local, state, and national levels (CMS Office of Public Affairs,
2010). Quality improvements are focused not only on the metrics outlined for eligible
providers and eligible hospitals relative to their care of patients, but also to improve
population health by empowering the patients to have more autonomy through access to
their electronically protected health information (EPHI) (CMS Office of Public Affairs,
2010). In addition to the three stages of meaningful use criteria, the software technology
used by eligible providers and eligible hospitals must be ce1iified by an Office of the
National Coordinator (ONC) Authorized Testing and Certification Body (ATCB) to be
eligible for incentive payments (Centers for Medicare and Medicaid Services, 201 0).
Incentive payments are based on Medicare and Medicaid patient encounters acl'oss the
14
aforementioned three phases spanning multiple years depending on the payer (President
Barrack Obama, 2009).
The Medicare EHR Incentive Program began in 2011 and offers eligible providers up to
$44,000 with a decreasing annual sliding incentive payment scale over a five year period
(CMS, 2010). For eligible hospitals, there is a base incentive payment of$2,000,000 and
additional monies depending on the number and type of patient encounters (CMS, 2010).
Begim1ing in 2015, however, physicians and hospitals that do not use certified products
in a meaningful way will be penalized by Medicare on a sliding scale of 1% in 2015, 2%
in 2016, and three-five percent for subsequent years (President Barrack Obama, 2009).
The Medicaid EHR Incentive Program provides similar incentive payments for eligible
providers, but the provider or practice must choose either Medicare or Medicaid, not
both. Under Medicaid, the eligible providers are allowed to receive up to $63,750 with a
decreasing ammal sliding incentive payment scale over a six year program pmiicipation
period. For eligible hospitals, they too begin with a $2,000,000 base payment, and have
the choice of pmiicipating in both the Medicm·e and/or Medicaid EHR Incentive
Programs (CMS, 2010). CmTently, there are no payment adjustments under the Medicaid
EHR Incentive program for eligible providers and hospitals that are unable to achieve
their goals within the given timeline (CMS, 201 0).
The HI-TECH Act also provides two billion dollars for discretionary spending under the
management ofONCHIT, and establishes a goal aforementioned in the President's state
of the union adch-ess, that the people of the United States of America will have electronic
health records being utilized by 2014 (President BmTack Obama, 2009).
15
Further, in 2010, the Patient Protection and Affordable Care Act (PPACA), was signed
into law. One of the goals of the PP ACA is to better connect the quality of care with
reimbursements for that care in an effort to reduce wasteful spending and decrease related
costs. This is to be achieved by creating new payment methodologies, delivery models,
and value-based purchasing programs, also known as pay for performance (P4P). There
will be mandated checks and balances in place specific to quality reporting (American
College ofEmergency Physicians, 2011). The act also establishes the Center for
Medicare and Medicaid Innovation (CMI). CMI is working with providers, payers, and
advocacy groups at the Federal, State, and local levels to gather their input in an effort to
remodel and propagate new models of more cost effective delivery of quality healthcare.
In so doing, CMI' s focus on improving the quality of care and coordination provided to
patients and their resulting outcomes will be the foremost task at hand, while also looking
forward at the formulation of effective community care models (Sharamitaro, 2011).
Dentzer (2011) takes a pulse ofhow much improvement has been made as it relates to
patient safety and quality of care in the US healthcare industry since the publication of
the IOM's "To Err is Human" report. Notably, the article suggests that while there have
been significant quality improvements made, they are slow coming and that the initial
problems identified could be much worse than first anticipated. Dentzer alludes to the
fact that as the research methodologies advance so too does the uncovering of more
quality issues (Dentzer, 2011). Of the notable quality improvements that have been made
across the country, one common denominator is that healthcare quality is impmiant
enough to be addressed consistently at a national level. National organizations such as
16
the Centers for Disease Control and Prevention (CDC), Institute for Healthcare
Improvement, and the Joint Commission on Accreditation ofHealthcare Organizations
(JCAHO) are working in conjunction with providers throughout the country on quality
improvement processes (Pronovost, 2011; Chassin, 2011). Similarly, this can be also seen
in national healthcare provider organizations, such as Ascension Healthcare Delivery
System and Veteran's Affairs (VA) through their commitment to improving quality of
care (Pryor, 2011; Trivedi, 2011).
Both public and private stakeholders, comprised of state and federal agencies, providers,
payers, and regulators across the US have found middle ground in developing common
quality standards to measure in reducing Intensive Care Unit (ICU) based central line
blood stream infections (Pronovost, 2011). Forty-five states participated in the effort and
a 62% reduction outcome was validated by the Centers for Disease Control and
Prevention, between the years 2001 and 2009 (Pronovost, 2011). The success was
attributed to the ability of interdisciplinary teams in local hospitals working together at
the state level, states sharing with one another to the point that a national social
community was formed, and then formalized by the American Hospital Association
(AHA) (Pronovost, 2011). Support from Quality associations such as JCAHO in
conjunction with support by payers both private and public supplied the regulatory and
reimbursement initiatives to assist providers in developing goals and reaching them
successfully in a standard, unified approach (Pronovost, 2011).
17
Ascension Healthcare Delivery System sought quality improvement in 2003 for a number
of areas such as preventable deaths, trauma related to births, pressure ulcers, ventilator
associated pneumonia, and hospital acquired infections (Pryor, 2011). The Board of
Directors backed a clinical excellence team who was responsible for overseeing the
quality standards (Pryor, 2011). Executive compensation was further tied with quality
performance and each hospital's results were compared nationally with one another
(Pryor, 2011). From this, hospital pminerships created quality teams called Affinity
Groups m1d developed quality indicators called Change Packages that were used
throughout their sixty-nine hospitals that span twenty states (Pryor, 2011). The quality
initiatives were encompassed in organizational govemance structure and most notably,
during the yem·s 2004-2010, preventable deaths were significantly decreased on average
of one thousand five hundred per year (Pryor, 2011 ). In addition, Ascension's
performance when compared with national averages in 2010, revealed reductions in
system neo-natal mortality rates of 89 percent, birth trauma rate of 65 percent, pressure
ulcers rates of 94 percent, ventilator associated pneumonia rates of 7 4 percent, and
hospital acquired infection rates of 43 percent (Pryor, 2011).
Trivedi and colleagues focused on another national quality endeavor from the perspective
ofthe VA (Trivedi, 2011). While the VA has made great strides in improving healthcare
quality for our nation's veterans, the outcomes related to racial disparities were studi~d
tln·ough process of care delivery and clinical outcome measures (Trivedi, 2011 ). The
quality indicators measured were comprised of diabetes, cardiovascular disease,
hype1iension, and cancer screenings from years 2000-2009 in most cases (Trivedi, 2011).
18
From the data, all quality performance rates showed improvement over time, other than
mammography (Trivedi, 2011). However, there were findings of significant racial
disparities in clinical outcomes between whites and blacks with the blacks having more
problems in the areas of blood pressure, glucose and cholesterol (Trivedi, 2011). While
this study is specific to the VA, it alludes to other identical publicized trends outside the
VA as it relates to the US population where it seems improvements are being made for
blacks, but a lower rate than for whites (Trivedi, 2011).
Recent research with a focus on adverse advents in hospitals, as they relate to patient
safety, found that current measures in the United States could be missing the majority of
adverse events and therefore only truly account for ten percent of the total (Classen,
2011). This was exemplified by a study comparison of measures across three hospitals
consisting of volunteer reporting, the Agency for Healthcare Research and Quality's
(AHRQ) Patient Safety Indicators, and the Institute for Healthcare Improvement's Global
Research Tool (Classen, 2011). Of the three measures, the implementation of the Global
Trigger Tool, which is defined as a new and improved intense chali review, revealed that
ten times more adverse events than usual were found throughout the records in
comparison with the other measures described that are used and accepted today (Classen,
2011). The bottom line is that there is plenty of room for improvement not only in
quality, but also in how it is measured across US Hospitals.
With exan1ples like these in mind, JCAHO is looking to the future and focused on a
consistent approach to preventing even the smallest of enors in hopes to achieve a more
19
reliable quality experience for patients (Chassin, 2011). As it stands today, there are
described pockets of excellence across the US where organizations are surpassing quality
standards in some areas and then failing in others (Chassin, 2011). With this in mind,
JCAHO has its sights set on further establishing a high reliability model by developing
standards that are achievable, but are more consistently met over time across all quality
standards, not just some of them (Chassin, 2011 ). This is based on the principle of
collective mindfulness, when applied to healthcare would mean that all workforce would
understand the necessity of care quality and the high stakes involved when something
goes awry (Chassin, 2011). The creation of high reliability organizations can be achieved
when an organization's leadership commits to the goal, develops and allows the
organizational culture to support the goal, and enables the workforce to adopt robust
process improvements such as six sigma and lean management to reach the stated goal
(Chassin, 2011).
With more than ten years of focused growth in the patient safety and quality movement,
mandated use of electronic health records through an incentive, and then disincentive
program for non-participants, and reduction in Federal Medicare reimbursements with no
budgetary end in sight, it has become clear that the stage is being set for the shift to pay
for performance (P4P) in an incremental, yet swift fashion.
Theoretical perspectives - Healthcare Information Technology
Primary literature findings on Electronic Health Record (EHR) adoption, diffusion, and
acceptance theories yielded varying theories and models comprised of the following: 1)
Diffusion oflnnovations Theory (Rogers, 1962; Ford, 2006); 2) Bass Diffusion Model
20
(Bass, 1969; Ford, 2006); 3) Technology Acceptance Model (TAM) (Davis, 1989; Hyun,
2009); 4) Task-Technology Fit Model (TTFM) (Goodhue, 1995; Hyun, 2009); 5)
Grounded Theory (Glaser, 1967; Yoon-Flannery, 2008); 6) Game Theory (Nash, 1950;
Klarreich, n.d.; Woodside, 2007); 7) Resource Dependency Theory (Pfeffer, 1978;
Bramble, 2010); and 8) Combinations therein.
For purposes of this study, the researcher chose TAM as the theoretical framework
because it is an accepted technology theory in the literature related to healthcare
information technology implementations specific to electronic health records and nursing
documentation systems. Ten percent of all information systems publications use the
TAM, with thiliy to f01iy percent of IT acceptance attributed to reviews ofthe basic
theory (Holden, 2010).
TAM is an information systems theory that models how user attitudes or behavioral
intentions to use a technology compare with how they actually use the teclmology. TAM
hypothesizes that a user's intended behavior predicts actual system use, and that external
variables, such as human and social factors, indirectly determine an individual's attitude
toward technology acceptance by influencing perceived usefulness and perceived ease of
use (Morton, 2009). Davis defined perceived usefulness (PU) as "the degree to which a
person believes that using a particular system would enhance his or her job performance",
and perceived ease-of-use (PEOU) as "the degree to which a person believes that using a
patiicular system would be free from effort" (Davis, 1989a, pg. 320). Both vm·iables
perceived usefulness and perceived ease-of-use are used in conjunction with one another
21
to formulate the person's, or end user's, intentional behavior towards a technology.
Intentional behavior is defined as "the degree to which a person has formulated conscious
plans to perform or not perform some specified future behavior" (Warsaw, 1985 pg. 214).
The final variable is actual system use and it is essentially the end result of how the end
user did in fact use the system. It is postulated that actual system use is derived in part
from the end user's behavioral intention towards an information teclmology (Davis,
1989b).
Motion and Wiedenbeck (2009) used the TAM in conjunction with the Diffusion of
Innovations Theory to identify and determine which factors contribute to physician
acceptance of an EHR system. They analyzed 239 usable self-reported online
questionnaire responses out of an eligible 802 total physicians at the University of
Mississippi Medical Center in 2007 (Morton, 2009). The study was open for participation
across all thirty one specialties and the online survey was communicated to physicians
via three different email notifications (Morton, 2009). The Like11 scales based survey
used five response levels consisting of the following: Strongly agree, Agree, Neutral,
Disagree, and Strongly Disagree (Morton, 2009). These factors are represented across
three categories: physician characteristics, social factors, and teclmical factors.
Specifically, theses factors included management support, physician involvement,
adequate training, physician autonomy, doctor-patient relationship, perceived ease of use,
perceived usefulness, and attitude about EHR usage. The goal was to measure the factors
of these characteristics for influential attitudes related to EHR use, using the variables PU
and PEOU. Results showed that "Perceived usefulness (PU) had the strongest impact on
22
attitude about EHR use, with physician involvement. Perceived ease of use (PEOU) did
not directly impact attitude about EHR use as hypothesized" (Morton, 2009).
In a follow-up study, Morton and Wiedenbeck (2010) again were measuring which
factors, social or technical, would impact ambulatory EHR adoption attitudes in
physicians. Prior data was utilized and comprised of 23 9 physician responses to a survey
across thirty-one specialties at the University of Mississippi Medical Center (Morton,
2009). Similarly, the specific factors explored in this acceptance study include physician
perceptions of computer skills and training, management support, physician involvement
and participation in the process, physician autonomy, the doctor-patient relationship,
perceived ease of use, and perceived usefulness. Physician attitudes were assessed before
and after EHR implementation in the pre-post fashion. Results revealed perceived
usefulness to be the significant predictor before and after implementation. In addition,
"concerns regarding patient privacy, interference with physician-patient rapport,
workflow, efficiency, and autonomy were found" (Morton, 201 0).
Lastly, the TAM is utilized in conjunction with Task-teclmology Fit Theory by Hyun
(2009). This study uses nurses' perceptions related to their documentation needs in order
to design an effective electronic nursing documentation application (Hyun, 2009). The
study took place at Columbia University College of Nursing and academic teaching
hospital. Methods consisted of a brainstorming sessions with nursing, n= 2, followed by
an: interactive collaboration in system design on paper, next, the user interface was
created and evaluated by nursing, n= 5, and lastly nurses pmiicipating in the study
23
completed surveys related to perceived usefulness and perceived ease of use on a seven
point Like1i scale (Hyun, 2009). Study specific factors were quality, locatability,
authorization, compatibility, ease ofuse/training, production timeliness, systems
reliability, and relationship with users. Results yielded perceptions of ease of use and
usefulness of interface screens for nursing staff. In addition, the interface screens
fulfilled the need for nursing documentation related to Nursing Admission Assessment,
Blood Administration, and Nursing Discharge Summary. By developing the system with
the clinical end user, most documentation needs, described as documentation efficiency
and patient safety as functional requirements, were understood and met thereby leading to
a successful endeavor.
NICU user performance and associated technologies- Integrated Review
Past topics of performance measurement, as it relates to actual infonnation teclmology in
the literature are portrayed in multiple ways. The broadly described components from
which the measurements are comprised, include a number of different technologies,
clinical settings, end users, and related patient outcomes over the past decade. From a
teclmical perspective, the technologies being used are in the form of software, hardware,
or a combination therein with free-standing and/or mobile configurations. The clinical
settings are primarily hospital NICUs of varying size. The clinical setting is focused on
NICU sub-specialty units in hospitals. The end users are generally comprised of primary
clinical staff in the form of physicians, physician residents, and pharmacy staff, and
various nursing staff. Clinical outcomes are comprised of actual patients whose
24
treatment was delivered both with and without the assistance of technology. Provider
outcomes are compromised of how well the user of the technology performed
individually or in aggregate, and lastly, technology outcomes as they relate to effectively
eliminating problems they are implemented to solve. Put simply, the effectiveness of
different technology interventions are described next and are generally measured by the
performance of the end user, the clinical outcome experienced by the patients, or a
combination ofboth.
A study was conducted at Fairfax Hospital NICU to measure the turn around times on
ordering, processing, delivery, and the overall quality of parenteral nutrition (PN)
therapies for neonates (Puangco, 1997). For each PN order, a data collection sheet was
attached and filled out by the ordering physician neonatologist and the processing
pharmacy technologist (Puangco, 1997). After one year time intervals, data was
collected for two week periods before and after the implementation of an in-house
developed interventional software used to automated the process (Puangco, 1997). Mean
differences across both time periods were measured using unpaired t-tests (Puangco,
1997). Thirty nine patients received PN prior to the intervention and forty two patients
received PN after the intervention. Results revealed a decrease of three minutes per order
for neonatologists (Puangco, 1997). In addition, improvements were shown in pharmacy
staff efficiencies and dietician calculations which played a pmi in increasing the nutrient
quality and thus energy levels of neonate patients (Puangco, 1997).
25
Another study focused on PN en-or prevention and teclmology user satisfaction at Johns
Hopkins Hospital NICU (Lehmann, 2002). An order entry software program was in
house developed to replace the paper based methodology. This was coined the total
parenteral nutrition (TPN) calculator. This instrument served as a quality improvement
and was designed in conjunction with the decade old existing paper form. Data collection
for the baseline period consisted of forty three days, with the intervention period lasting
46 days (Lelunmm, 2002). The data elements were defined as the number of nutrition
orders, frequency and en-or type. Afterwards, a personal experience and opinions survey
was conducting online to physicians, pharmacists, and nurses. In the baseline period 557
orders were compared with 471 orders from the intervention period (Lehmmm, 2002).
Results showed a 61% en-or reduction rate, in that for every 1 00 TPN orders, m1 average
of 10.8 were errors prior to the intervention compm·ed with 4.2 after the intervention
(Lehmmm, 2002). The survey results revealed that the TPN calculator was scored as a
1.5, or easy to use based on a numeric ranking scale of 1-5 with one being the easiest
(Lehmann, 2002). A Likert scale of strongly agree, agree, neutral, disagree, agree was
used to measure how the end users liked the paper form compared with the TPN
calculator (Lehmmm et al., 2002).
Further, Physician residents at the University of Washington NICU were evaluated for
performance with clinical documentation software while using a Personal Digital
Assistant (PDA) in order to improve accuracy and consistency (Cm-roll, 2004). The study
duration was eight months, consisting of a base time period four months prior to the
implementation and four months after, with forty days being randomly selected and taken
26
into consideration for analysis. Measures included patient weights, medications and
vascular lines documented in the progress note that did not match pre-defined standards
from nursing flow-sheets, assessments and medication administration records collected
prior (Carroll, 2004). The baseline period evaluated 339 progress notes and the
interventional period evaluated 432 progress notes. Logistic regression yielded initial
increases, but once covariates were controlled, there were varying results in that PDA
related documentation for patients weights was found to have less discrepancies, while
there was no substantive change for medications and vascular lines (Carroll, 2004).
Ultimately, the PDA's were removed from the NICU and they moved back to the
baseline documentation, while recommending more research in the use ofPDAs was
necessary.
As it relates to clinical outcome based performance measures, The Ohio State University
Medical Center NICU implemented Computerized Physician Order Entry (CPOE) in
their NICU in an effo1i to reduce medication error rates and improve medication turn
around times. Data variables included medications of caffeine and gentamicin. Both the
baseline and intervention samples contained 1 00+ very low birth weight infants, with the
study ranging from six months prior to six months after implementation (Cordero, 2004).
Statistical analysis were comprised of descriptive statistics (frequency counts,
percentages, mean and standard deviations), unpaired t-tests, and chi-square tests. Results
showed significant decreases in both medication rates and turn around times attributed to
the CPOE software functionality (Col'dero, 2004). Average turn around times decreased
fi·om 10.5 hours to 2.8 hours and were statistically significant, p<.Ol. Specifically, the
27
volume of neonates receiving medications within the 2 hour and three hour ranges
increased from 10% to 35% and 12% to 62% (Cordero, 2004). As it relates to medication
errors, the baseline period accounted for 13% dosing mostly due to overdoses and
underdoses (Cordero, 2004), compared to the interventional period where all medication
dosing errors were non-existent (Cordero, 2004).
During 2004 and 2006, a study at the Madigan Army Medical Center (MAMC) NICU
was conducted in accordance with the implementation of a CPOE system (Taylor, 2008).
The study measured the medication administration variances over a period of 21 months
with the orders being collected by hand for the first twelve months and then using the
interventional CPOE system for the remaining nine months (Taylor, 2008) . The
frequency of variance during both periods was identified through an representative
observational study whereby research nurses actively watched the nursing participants
administer medications to patients (Taylor, 2008). Thi1iy three nurses out of forty two
total participated in the study and over 250 medication administrations were observed in
both time periods (Taylor, 2008). Results showed that prior to the implementation of
CPOE, there were 19.8% variances detected during medication administrations and
afterwards this decreased to 11.6% (Taylor, 2008). Early or late administrations, defined
as those given 60 minutes early or late, comprised 53.1% of all variances (Taylor et al.,
2008).
Another notable measure of performance is described as system performance, as
portrayed in a study measuring self reported medication errors in the MEDMARX
28
anonymous national database reporting tool for hospitals. NICU enors related to
computer entry systems and more advanced CPOE systems were queried with a total of
343 results across 48 hospitals found (Chuo, 2008). Of those enors, 248 were found in
the computer entry systems, while 45 were attributed to CPOE (Chuo, 2008). The
associated phases of the medication process in which the enor occuned consisted of
procurement, prescribing, transcribing/ documenting, dispensing, administering, and
monitoring. Over sixty percent of the errors in the computer entry systems can be linked
to the transcribing/ documenting phase, while over seventy five percent of enors can be
tied to the prescribing phase in CPOE (Chuo, 2008). Of these errors, the most influential
error types were comprised of improper dose/ quantity at 36.2% in the computer based
entry system and prescription error at 62.2% in the CPOE system (Chuo, 2008).
In2009, Rikli performed a qualitative study at Helen DeVos Children's Hospital NICU
centered around the concept of using micro systems and quality improvements to
successfully implement an electronic documentation system following a failed attempt.
Microsystems are described as any participant involved in the healthcare of a patient.
Thus clinical linkages within departments amongst providers and patients are significant
when trying to problem solve. After the failed implementation attempt two years prior,
staff was surveyed about problems and what was needed to be successful. Of the
findings, technical problems in terms of access to workstations and speed of computers
were identified, along with the need for extended practice time and more experienced
trainers to help them use the software program (Rikli, 2009). An interdisciplinary quality
29
team was formed and monitored the progress throughout the second project
implementation which lead to a successful endeavor (Rikli, 2009).
Lastly, a lesson's learned miicle related to the implementation of CPOE at Mission's .
Children's Hospital NICU. The NICU is comprised of a 50 bed unit and was chosen as
the pilot site (Ramirez, 201 0). The critical aspects of the implementation described relate
to clinical team building and communication, physician leadership, sequencing every
aspect of each order set, direct access to programmers for system changes, m1d real time
testing scenarios with self paced training (Ramirez, 201 0). These lessons learned lead the
NICU to a successful implementation of CPOE along with a successful impact on patient
cm·e and safety (Ramirez et al., 2010).
In summary, the quality of care patient safety movement is transforming like never before
in the field ofhealthcare. This focus is easily seen through the spurred implementation of
electronic health records, the evolution of performance and quality of care standards, and
lastly, the linkages with direct reimbursement for healthcare providers. Thus, the
importance ofunderstm1ding how to become successful users ofteclmology across the
healthcare spectrum has never been greater.
IV. Conceptual models
For the study, I am going to utilize the core conceptual model of TAM (see Figure 1a),
described as a measure of end user teclmology acceptm1ce through two subjective
vm·iables, perceived usefulness and perceived ease of use (Davis, 1989). Again,
30
behavioral intention to use a system is comprised of these variables and relates
specifically to .actual system use (Davis, 1989b ).

Figure lb: Core Conceptual Study Model

Actual System Use Technology 2 (Cribnotes t+6m)
More specifically, I will be looking at the acceptance of an electronic health record
technology, Cribnotes, through the perspective ofNICU nursing staff by measuring not
only the traditional TAM subjective variables of perceived ease of use and perceived
usefulness by individual nurses, but also utilizing objective performance data of the same
nurses on a past information technology, Medication Administration Checking (MAK)
(see Figure 1b) (Grand Rounds Software, 1994; Siemens, 2002). Additional independent
31
variables of nursing staff measured will be age, gender, race, professional degree, and job
title. Lastly, actual system use of the Cribnotes technology will serve as the dependent
variable and will be measured by objective performance data. This is depicted in
Appendix 1- Figure 2 in detailed fashion. I am interested in the value of measuring my
conceptual model across one year of time, as users' attitudes and behaviors may change
over time. The first measure will encompass a time period of six months prior to the
implementation of the Cribnotes system and the second measure will be six months after
the system is implemented. My hypothesis states'that MAK objective nursing
performance data will be the primary predictor, or will have the most impact, of the
Cribnotes objective nursing performance data. If this holds true, the TAM as it stands
today needs revision, either to 1) include the objective use data variable in an expanded
model, or 2) to eliminate the need for the TAM and rely solely on the objective use data
as a stand-alone predictor.
V. Research Questions and hypotheses
Research questions for this study include: 1) Will RN historic system performance be a
better predictor of future system use than utilizing their attitude, or behavioral intention to
use it? 2) Will RN historic system performance work in conjunction with RN behavioral
intentions to explain more R squared variability together, rather than independently? 3)
Were clinical, social, and/or teclmical factors identified that can be added as subjective
variables to enhance future analysis ofR squared findings related toRN performance?
32
HI: The MAK objective nursing performance score will be the primary predictor, or will
have the most impact, on the Cribnotes objective nursing performance score when
compared individually with all other independent variables.
H2: The MAK objective nursing performance score will be the primary predictor, or will
have the most impact, on the Cribnotes objective nursing performance score when
compared with all other independent variables in aggregate.
H3: The MAK objective nursing perfonnance score will work in conjunction with RN
behavioral intentions to create a more explanatory framework.
H4: The full model consisting ofMAK objective nursing performance score and the pre
implementation subjective RN behavioral intentions will explain all the variation in the
dependent variable, Cribnotes objective performance score.
VI. Methods and Materials
This study uses quasi-experimental research design with data being collected before the
implementation of a new technology and six months after the implementation.
The study is quantitative and spans across two time periods in a longitudinal fashion
within the course of one year. Other characteristics are relevant in that the approach of
the study is pre-post in nature, as the researcher is describing and measuring both
subjective behavioral attitude scores utilization patterns across two different types of
technologies over time. Data is already being captured as part of system functionality so
the costs of the study are minimal.
33
The researcher will assign nursing performance scores for specific, time sensitive
variables within each system. The performance scores will be measured across time
periods throughout the year relative to the Cribnotes Go-Live date of July 11, 2011 (T),
begilming with the use of historic MAK performance scores in January, 2010 (T-18m),
and then 18 months later upon the intervention capturing the Cribnotes performance
scores through January, 2012 (T+6m). Cribnotes perfonnance scores will be measured at
time periods T +6m. In addition, TAM based nursing surveys were given to the
participants prior to the implementation of Cribnotes in order to gain an understanding of
their behavioral intentions towards these current and future technologies. In so doing, the
users' behavioral intentions can be measured independently and in conjunction with the
perfom1ance scores of the MAK technology in an effmi to predict and explain nursing
utilization pattems of the Cribnotes technology. Additionally, the same survey, with
slight modifications adapting it to past tense, will be administered a second time to the
same nursing staff six months post-implementation of Cribnotes. Figure 3 depicts the
time periods of the before and after design study.

This study is being performing in an effort to model NICU nurse utilization of electronic
health record documentation technologies, one of which is currently used hospital wide,
including NICU, and the latter, to be utilized as a specialization system only within the
NICU. The NICU's current module of documentation teclmology, more specifically,
medication administration checking at the point of care (MAK), will continue to be used
in conjunction with a new modular technology, Cribnotes, a nursing documentation
system, as the NICU moves to a comprehensive electronic· health record. This pre-post
study will use breast milk verification/administration times by nurse as the variable of
measurement. The breast milk variable was selected because it is a nationwide quality
35
goal and is· indicative of a key NICU measure directly tied to nursing documentation
performance (AAP, 2012). This variable is used in the MAK system for the first six
months of the study, and then is used in the Cribnotes system for the remaining six
months of the study. Both of the applications, although developed by different
companies, maintain a modem user interface related to aesthetics, and very similar
functionality in terms of measurements ofbreast milk verification/ administration as
quality checks.
IRB approval
The University of South Alabama Institutional Review Board approval was requested and
granted prior to·this human-subjects research study. University of South Alabama
Children's and Women's Hospital nurses participating in the study did so at their
discretion and could leave the study at any time.
Sample
The sample population consists of the NICU nursing staff at the University of South
Alabama Children's and Women's Hospital, Department of Pediatrics, Division of
Neonatology. The sample size consisted of 146 potential participants whom were
requested to be a part of the initial study. The initial participation level prior to the
implementation of Cribnotes consisted of 95 out of the 146 potential participants or 65%
response rate. The sample size from the second administration of surveys six months after
the implementation of Cribnotes consisted of 14 7 potential participants. Of this group
130 out of the 147 or 78% chose to pmiicipate. Those whom pmiicipated in the original
36
survey were all included as potential participants for the second survey. Their response
rate was 81 out of the initial 95, with 14 of the participants leaving the study due to
reasons such as they simply didn't want to fill out another survey, were out on maternity
leave, or were no longer employed by USA Children's and Women's Hospital NICU.
Upon review, an additional 12 participants were un-eligible for the study because they
had not utilized the MAK system. Therefore, there were a total of 69 study participants.
The nursing staff participants identified were kept confidential, thus minimizing the
study's risk, and have been re-coded with an assigned number to track their performance
throughout the stuqy.
Data Sources
Data sources for this study are comprised of two separate clinical application system
databases and survey data from the NICU Nurse Survey instrument. The MAK system is
primarily used to perform quality checks on medications administered and document all
associated information electronically. It serves as a critical module for a comprehensive
EHR and is utilized hospital-wide by nurse staff. The data from the MAK information
system is collected real-time and is currently utilized by the NICU Nurse Manager to
assess nursing performance as it relates to patient safety and quality of care. The data is
also utilized by the hospital's Department of Quality Management for JCAHO purposes.
The Cribnotes information system captures additional data fields unavailable 1n MAK
that were historically recorded in paper format. Upon the implementation of Cribnotes,
the NICU will be capturing information related to nursing documentation in the areas of
assessments, nursing diagnosis, goals or expected outcomes, nursing actions or
37
interventions, evaluations, I/Os, and overall care plan. Cribnotes will serve as the
comprehensive EHR for the NICU, to be used in combination with the MAK system.
Similarly, reports from the system will be utilized in the same fashion. The survey
instrument will measure intended behavior of the nursing staff as it relates to utilizing
both technologies, specifically, ease of use, described as the impact on nursing workload,
and usefulness, described as the quality of patient care.
Data Source 1- MAK Database
The first database used in the study is the MAK database, which houses patient
information directly related to point of care medication administration performed by
NICU nursing staff. The data for medication administration delivery times is tied directly
to each nurse user within the information system. The primary variable to be analyzed
will be breast milk verifications/administrations given by the nurse to the patient. The
researcher will analyze this data by organizing and presenting the information by nurse
user that will be the basis for individual nursing performance scores. The primary MAK
variable will be measured by verification/ administration times that were either delivered
"on-time" or "early/ late".
Data Source'2- Cribnotes Database
The second database will be that of Cribnotes, which began on July 11, 2011 and will
collect all data input into the system. Again, all the nursing documentation performed by
users will be directly linked to them individually. This will allow the data to be tracked
by the researcher, in order to identify quality metrics that will be the basis for individual
38
nursing performance scores. The primary variable to be analyzed will be breast milk
verifications/administrations given by the nurse to the patient. The data will be organized
into a report through access to the Cribnotes SQL database. The primary Cribnotes
variable will be measured by verification/administration times that were either "on-time"
or "delivered early/ late".
Data Source 3- Pre and Post Survey Instrument
Please see Appendix 2 to see the survey instruments used in this study. The pre
implementation survey instrument consists of basic demographic information such as,
age, gender, race, professional degree, position title. In addition, the survey contains four
questions that gage the nurses' perception of how the technology would affect their
. workload and quality of care given to patients. Questions 1 and 3, point specifically to the
ease of use of each technology as they relate to the MAK technology's current impact on
nursing workload, as well as the expectation of future impact of the Cribnotes
technology. In addition, the remaining questions (2 and 4) are directly related to the
MAK technology's current usefulness of improving quality patient care, as well as, the
expectation of future impact ofthe Cribnotes technology.
The post-implementation survey instrument consists of basic demographic information
such as, age, gender, race, professional degree, position title. The survey contains the four
same questions as the pre-survey correcting for pre/ post tenses and asks the nurse's level
of agreement with how the two technologies affected their work load and quality of care
given to patients. A comments section was added in an effort to allow nurses to provide
39
feedback about their experience over the past six months using the MAK and Cribnotes
systems. The comments section was left open intentionally in order to not push the RNs
to an answer, but rather allow them to speak freely after having experienced the systems.
Also taken into consideration was the impact of nurses being somewhat restricted in
answer choices when filling out the agree/disagree portions of the survey, and thus a
broad approach was instituted to capture anything on their mind about their experience.
The survey was self administered and completed in the NICU during the patiicipants'
work shift. Confidentiality was maintained in that I collected the surveys from the
participants throughout 2 different shifts (12 hr shifts; 7atn-7pm; and 7pm-7am) and
stored them in a locked drawer in a locked room, in a separate secure building. The
surveys were then input into excel, de-identified, and m·e backed up and stored on a
secure server. The survey was a stand alone, not linked to other data sources. I am able to
link the surveys and the system use data (MAK and Cribnotes breast milk administration
documentation reports) to the individual nurses by their names, which have been de
identified/ changed to numbers for confidentiality purposes.
Data Collection Time Intervals
Data analysis on the defined data sources will take place with the primary reference point
of "Cribnotes Go-Live" (Time period = T) once the intervention system has been
implemented a11d users begin working on the system. The Cribnotes system was
implemented on July 11, 2011. A two year time period measured as snapshots of nursing
utilization at averaged time periods will be at T- 18 months for the MAK system
40
specifically, and Cribnotes at T+6 months. As it relates to the pre-implementation survey,
the data collection time period spanned a 15 day timeframe that took place prior to the
Cribnotes Go-Live (Time period= T). The post-implementation survey was also
administered over a fifteen day timeframe that took place six months after the Cribnotes
Go-Live.
Intervention
The primary intervention used for this study is the implementation of Cribnotes
information system. This electronic documentation system will serve as the second
significant piece of patient documentation software to be adopted by NICU nurses. This
intervention will be used to test hypothesis H1, H2, H3, and H4.
Scoring Calculation
The measurements for each technology will begin with deriving an objective and
subjective performance scoring methodology for MAK and Cribnotes. This study will
measure these NICU nursing perfmmance scores over time. The objective use data is
specific to measuring nursing documentation performance and will be analyzed across
both systems. Each system provides modular functionality as it relates to a
comprehensive electronic health record for the NICU and as such, are used in conjunction
with one another to assist in providing specialty patient care. For purposes of this study,
the variable to be measured within the MAK system will be breast milk
verification/administration times, which shifts from MAK after the Cribnotes intervention
and is then measured in the Cribnotes system for the second period. The breast milk
41
quality measure is a nationwide goal and is indicative of a key NICU measure directly
tied to nursing documentation performance (AAP, 2012).
The scoring methodology related to the documentation performance ofMAK medication
administration times is comprised of nursing timeliness of breast milk
verification/administration given by assigning a two tiered point system for being either
"on-time" or "early/late". The data will consist of all verifications/administrations by
each RN within the base period (T -18 months). Each nurse breast milk
verification/administration will be assigned a "1" or a "0". A score of a "1" represents the
breast milk being verified/ administered on time. "On time" is defined as a medication
being verified/ administered less than thirty minutes early and not more than thi1iy
minutes late. A "0" will be assigned for all medication verification/administration times
where medications were given beyond this one hour threshold and were thus early or late.
For measurement purposes, the scoring system's associated calculation will be based on
the outcomes related to the proportion oftimes the nurse verified the medication on-time
divided by the total number of times they performed the task.
The scoring methodology for nursing documentation performance, related to the new
Cribnotes system, will align with that fi:om the MAK system in that the primary variable
to be measured will be breast milk verification! administration documentation times that
resulted in a status of being "on-time" or "early/late". The data will consist of all
verifications/administrations by each RN in the interventional time period (T+6 months).
Each nurse breast milk verification/administration will be assigned a "1" or a "0". A
42
score of a "1" represents the breast milk being verified/ administered on time. "On time"
is defined as a medication being verified/ administered less than thirty minutes early and
not more than thirty minutes late. A "0" will be assigned for all medication
verification/administration times where medications were given beyond this one hour
threshold and were thus early or late. For measurement purposes, the scoring system's
associated calculation will be based on the outcomes related to the proportion of times the
nurse verified the medication on-time divided by the total number of times they
performed the task.
The survey scoring methodology applied to both the pre and post surveys will also follow
a "1" and "0" assignment. On the baseline, pre-implementation survey, the first survey
question, "Has the implementation ofMAK increased your nursing workload?" will be
assigned a "1" if the participant agrees and a "0" if the participant disagrees. The second
survey question, "Has the utilization ofMAK improved quality of care for patients?" will
be assigned a "1" if the participant agrees and a "0" if the participant disagrees. The third
survey question, "Has the implementation of CRIBNOTES increased your nursing
workload?" will be assigned a "1" if the participant agrees and a "0" if the participant
disagrees. The fourth survey question, "Has the utilization of CRIB NOTES improved
quality of care for patients?" will be assigned a "1" if the participant agrees and a "0" if
the participant disagrees.
On the post-implementation survey, the first survey question, "Has the implementation
ofMAK increased your nursing workload?" will be assigned a "1" if the patiicipant
43
agrees and a "0" if the participant disagrees. The second survey question, "Has the
utilization of MAK improved quality of care for patients?" will be assigned a "1" if the
pruiicipant agrees and a "0" if the participant disagrees. The third survey question,
"Expectation that CRIBNOTES will increase your nursing workload?" will be assigned a
"1" ifthe pruiicipant agrees and a "0" ifthe participant disagrees. The fornih survey
question, "Expectation that CRIBNOTES will improve quality of care for patients?" will
be assigned a "1" if the participant agrees and a "0" if the participant disagrees.
Analytical Approach
Data elements representing each of the three aforementioned data sources as they relate
to the general and specific theoretical constructs are shown below in Appendix 3- Tables
1, 2, and 3. Linear regression analysis (R-squared), correlations and descriptive statistics
will be utilized. The dependent variable (Y) will be represented as a proportion of times
RNs verified/ administered breast milk "on-time" divided by the total number of times it
was verified/ administered. An linear regression analysis will then be conducted to
measure the independent variables 1 (B 1 ), described as Technology 1 (MAK) actual use
performance scores, and independent variables 2, 3, 4, a11d 5 (B2, B3, B4, and B5),
described as Nursing Survey attitudes independently and in combination against the
dependent variable, described as Teclmology 2 (Cribnotes) actual use performance
scores. In addition, independent variable (B6) describing individual RN frequency, or the
number of times, breast milk verification/ administration occurred in time period T+6.
The model will utilize the full sample of 69 RNs.
44
Additional independent variables collected by the surveys include age, gender, race,
p1~ofessional degree, and position title. These demographic independent variables will be
examined using descriptive statistics in an effort to justify their relevance while
identifying any confounding impacts. Further, of the survey respondents, those eligible to
participate in the study and non-respondents will be compared in aggregate to gain a
better understanding of the NICU departmental demographics and adjust for any impacts
that may be realized.

As it relates to the open ended comments section of the post-implementation survey,
results will be qualitatively evaluated through the use of content analysis. Each comment
45
will be characterized independently. This qualitative analysis will be performed from the
perspective of and relevant to management decision making and technology use. This
effmi will be unde1iaken to better understand the problems that need to be addressed, if
any, and which variables could be incorporated in a follow-up study in terms of adding
more measures to increase understanding of variance.

VII. Study Results
In order to begin to address the study's research questions, a number of related
quantitative and qualitative statistical analyses were conducted. Results related to study
questions 1 and 2 were achieved tlu·ough quantitative analysis, while study question 3
relied on qualitative analysis. The approach to the quantitative analysis was to first,
explain the study sample and the composition of each study pruiicipant by analyzing the
demographic variables age, gender, race, professional degree, and position title. The
second approach was to describe the distributions of the pre-post implementation
subjective and objective variables related to the dependent variable. Third, correlations
amongst the subjective variables were also conducted. Lastly, linear regression analysis
was performed on all independent variables in order to compare the strength of their
relationships when explaining the varim1ce in the dependent variable. The approach to
46
the qualitative analysis was to first discuss the number ofresponses related to the entire
sample. Second, content analysis based on inductive reasoning was used for coding study
pruticipant comments obtained from the post-implementation survey. Third, the coded
statements were categorized in a hierarchical fashion in order to identify trends in
positive or negative statements related to the user experience.
Quantitative Analysis
Sample
The study population consists of the NICU nursing staff at the University of South
Alabama Children's and Women's Hospital, Department of Pediatrics, Division of
Neonatology. There werel46 potential pru·ticipants recruited to be a part of the initial
study. The initial participation level before the implementation of Cribnotes consisted of
95 out of the 146 potential participants or 65% response rate. The participation level from
the second administration of surveys six months after the implementation of Cribnotes
consisted of 147 potential participants. Of these, 130 out or 78% chose to pruticipate.
Those who participated in the original survey were all included as potential participants
for the second survey and 81 out of the initial 95 respondents pmticipated in the post
implementation survey. Reasons for dropping out included: Didn't want to fill out
another survey, were out on maternity leave, or were no longer employed. An additional
12 participm1ts were removed from the study because they had not used the MAK
information system, and thus did not have any scores to measure that were necessary for
47
purposes of the study. The final sample consisted of 69 NICU nursing staff for which
there was complete data (see Table 4).

Table 5 presents descriptive statistics of study pmiicipants, including age, gender, race,
professional degree, and position title. Age ranged from 25 to 65 yem·s old with a mean of
41 years old and a standard deviation of 10.079. Ninety-five percent ofthe sample was
female. Education level ranged from 68 (98.6%) RNs and 1 (1.4%) LPN, with 7
education levels ofRNs comprised of 1) RN-ADN, or Associate Degree in Nursing; 2)
RN-ADN-RNC, or Associate Degree in Nursing with an additional specialized nurse
training ce1iificate; 3) RN-ADN-RRT, or Associate Degree in Nursing with additional
training and participation on the rapid response team; 4) RN, Registered Nurse with no
specification of Associate or Bachelor degree; 5) RN-BSN, Bachelor of Science Degree
in Nursing; 6) RN-BSN-MSN, or Bachelor of Science Degree in Nursing and Master of
Science in Nursing; and 7) RN-BSN-RNC, or Bachelor of Science in Nursing with an
additional specialized nurse training certificate. Lastly, there were three categories related
to position title. These include: 1) LPN II-StaffNurse; 2) RN-StaffNurse; and 3) RN-
StaffNurse-Working Supervisor.

Multivariate Analysis
Subjective Use
Survey variables from pre-implementation and post-implementation of Cribnotes were
analyzed. Table 6 presents the distribution frequencies for each variable in terms of
whether or not the study participant agreed or disagreed.
Table 6: Survey response distribution frequencies

MAK perceived ease of use (82.6%) (17.4%) (60.9%) (39.1 %) 45 24 48 21
MAK perceived usefulness (65.2%) (34.8%) (69.6%) (30.4%) 60 8 42 27

Cribnotes perceived usefulness (46.8%) (53.2%) (44.1%) (55.9%)
All survey variables were then independently measured against the dependent variable
and represented through the use of histograms (Figures 4 and 5). The histograms resulted
in negatively skewed distributions as the Cribnotes performance scores generally ranged
from .4 to 1, or scores of 40% to 1 00%.

Survey response variables were correlated with one another in three different scenarios
using six combinations (Tables 7, 8, and 9). For purposes of this study, the variable of
interest measured within the MAK system was breast milk verification/administration
times, which shifts from MAK after the Cribnotes intervention, and is then measured in
the Cribnotes system for the second period. In other words, the nurses performed breast
52
milk verification qmi.lity checks first using MAK, and then using Cribnotes. The breast
milk quality measure is a nationwide goal and is indicative of a key NICU measure
directly tied to nursing documentation performance (AAP, 2012).
The first scenario is described as the relationship between nursing perceptions on "ease of
use," or increased workload, and "perceived usefulness," or improved quality of care,
related specifically to the old system (MAK) (Table 7). Nursing perceptions directly
related to MAK workload increase across both time periods of the study were compared
both with and without the breast milk variable of interest. Meaning more specifically,
that prior to the intervention, the breast milk verification was included in MAK and post
intervention it was not, because it was moved to Cribnotes. Chi-Square Tests revealed a
Pearson Chi-Square value of association at 4.624, p = 0.032. As it relates to effect size,
ranging from -1 to 1, Phi= .259, p = .032, represented a moderately strong association
between pre-post MAK ease of use. When both pre- and post implementation periods are
compared, nurses who perceived the system to be easy to use before they used it were
more likely to perceive it as easy to use after they had used it.
Nursing perceptions directly related to MAK quality of care improvement across both
time periods of the study were compared both with and without the breast milk variable
of interest. Chi-Square Tests revealed a Pearson Chi-Square value of association at 9.789
and a significance of .002. As it relates to effect size, ranging between -1 to 1, Phi= .377,
p = .002, represents a moderately strong association between pre-post MAK perceived
usefulness. When both pre- and post implementation periods are compared, nurses who
53
perceived the system to be useful before they used it were more likely to perceive it as
useful after they had used it.

The second scenario is described as the relationship between nursing perceptions on
"ease of use," or increased workload, and "perceived usefulness," or increased quality of
care, related specifically to Cribnotes (Table 8). Nursing perceptions directly related to
Cribnotes expected and actual workload increases across both time periods of the study
were compared. Chi-Square Tests revealed a Pearson Chi-Square value of association at
8.651 and a significance of .003. As it relates to effect size, ranging from -1 to 1, Phi=
.357, p = .003, represents a moderately strong association between pre-post Cribnotes
ease of use. When both pre- and post implementation periods are compared, those nurses
54
who expected the new system to be easy to use before they used it were more likely to
perceive it as easy to use after they had used it.
Nursing perceptions directly related to Cribnotes expected and actual perceptions on
improved quality of care for patients across both time periods of the study were
compared. Chi-Square Tests revealed a Pearson Chi-Square value of association at 7.044
and a significance of .008. As it relates to effect size, ranging between -1 to 1, Phi= .340,
p = .008, represented a moderately strong association between pre-post Cribnotes
perceived usefulness. When both pre- and post implementation periods are compared,
those nurses who expected the system to not be of use before they used it were more
likely to perceive it to be un-useful after they had used it.

The third scenario is described as the relationship between nursing perceptions on "ease
of use," or increased workload, and "perceived usefulness," or improved quality of care
to the patient, both after having used each respective system (Table 9). Put simply, the
nurses that used MAK before Cribnotes implementation report on whether or not their
workload and/or quality of care increased, and then report on Cribnotes in the same
manner post-implementation. Chi-Square Tests revealed a Pearson Chi-Square value of
association at 2.249 and a significance of0.134. As it relates to effect size ranging
between -1 to 1, Phi = .181, p = .134, represents the strength of association as a moderate
relationship between pre-survey MAK and post-survey Cribnotes ease of use, however,
insignificant. Even though, when both pre- and post implementation periods are
compared, nurses who used the old system and found it easy to use were more likely to
find they new system easy to use after they had used it.
Similarly, nursing perceptions represented by the variable "perceived usefulness" or
quality of care increase were compared after the individual implementations ofMAK and
Cribnotes. Chi-Square Tests revealed a Pearson Chi-Square value of association at 5.499
and a significance of .019. As it relates to effect size, ranging between -1 and 1, Phi=
.284, p = .019, represented a moderately strong association between pre-survey MAK and
post survey Cribnotes perceived usefulness. When both pre- and post implementation
periods are compared, nurses who used the old system and found it useful were more
lik~ly to find they new system as useful after they had used it.

The MAK performance score was plotted against the dependent variable Cribnotes
performance score (Figure 6). Both MAK performance score and Cribnotes performance
score were defined and formulated from the proportion of times a nurse verified/
administered breast milk within the proper time frame of 1 hour to a patient divided by
the total number oftimes the nurse verified/ administered breast milk in each respective
system. The scatterplot suggests a positive correlation of .265 between the variables.
Possible outliers investigated included study pa.J.iicipants 45, 47, 48, 53, 58, 59, 61. Each
57
outlier was investigated by looking up the actual performance score tied to the study
participant. In all cases, the outliers resulted from low performance scores and thus there
was no evidence that warranted the removal of these study participants scores from the
study.

In addition, a bivariate analysis was conducted on the MAK performance score and
Cribnotes performance score variables. This yielded a p value of .028, and thus a
statistically significant Pearson Correlation of .265, p< .05.
58
Regression Analysis
A linear regression analysis was conducted of the full model with the inclusion of an
additional variable signifying the number of times each nurse used the Cribnotes system,
or experience, for breast milk verification purposes (Table 1 0).

From the regression results it can be seen that the model is statistically significant (p<.05)
and explains on a very conservative level 14.7% of the variation in the Cribnotes
performance score. Related to the individual coefficients, the objective measure of
performance scores on the old system (MAK) is significantly positively related to the
performance scores on the new system (Cribnotes) (p < 0.05). Similarly, the pre-
59
implementation survey-based subjective measure result for Pre-Cribnotes Ease of Use is
also significantly positively related to the performance scores on the new system (p<.05).
Qualitative Analysis
To derive the results pertaining to research question 3, a qualitative content analysis was
conducted by using study participants subjective, post-implementation, survey-based
narrative comments. Of the 69 study participants, 35 responded with comments. In order
to identify the possibility that additional variables could enhance the model in future
iterations or applications, the comments were analyzed through an inductive reasoning
approach. All of the comments received were reviewed individually and coded into
subcategories from the ground up. The 35 comments were broken down even fu1iher into
73 sub-comments due to respondents making multiple statements. These sub-comments
were coded individually and if applicable, sometimes included multiple codes.
There were a total of 31 codes applied to the sub-comments. Frequency counts were
performed on each code at the base, or low level category. These 31 codes were then
grouped into 9 mid-level categories consisting of the following: 1) Clinical Application
Response (Positive); 2) Clinical Ease ofUse (Positive); 3) Clinical Quality Improvement
(Positive); 4) Clinical Impact (Negative); 5) Teaching Impact (Negative); 6) Workflow
Dependencies (Negative); 7) Application Specific (Negative); 8) IT Infrastructure
(Negative); and 9) Other. The 9 mid-level categories were then grouped into 4 high-level
categories that consisted of 1) Overall Clinical Impact (Positive); 2) Overall Clinical
60
Impact (Negative); Overall IT Impact (Positive); and 4) Overall IT Impact (Negative).
The results for the low, mid and high level categories are displayed in Figure 7.
Positive and negative connotations related to the initial comment response were used
within the categorizations. From a clinical perspective, examples of Overall Clinical
Impact (Positive) include positive comments such as, "MAK has increased quality of
patient care", and, "Cribnotes does make it easier to look back to keep continuity of
care". Conversely, examples of Overall Clinical Impact (Negative) include negative
cornn1ents such as, "A large amount of time is spent at the computer documenting and
less time is spent at the bedside", and, "Both MAK and Cribnotes has increased our
worldoad".
From a technology perspective, examples of Overall IT (Positive) include positive
comments such as, "MAK is good when the system works", and, "When systems are
operating they are fine". Conversely, examples of Overall IT (Negative) includes
negative comments such as, "Both systems are frequently down, making it difficult to
chart in a timely manner", and, "With logging in and out of the computer all day, less
time can be devoted to actual patient care". Additional negative technology comments
related to computer response time include, "Citrix needs to be revamped or switch to a
server that doesn't require freeze up at least two to tlu·ee times per shift", and, "I wish the
system was faster and could handle the large volume of traffic. The locking up and time it
takes to change between screens really slows up the process

These findings reveal that females scored nearly 20% points higher on the Cribnotes
system than on the MAK system and were also the sole respondents to the post-survey
comments at 37. Similarly, when evaluating ethnicity, white study participants increased
their performance score in the Cribnotes system by 19%, and were also the primary
respondents to the post-survey comments at 33. Professional degrees related to RN-BSN
group, representative of 60% of the study p3.1.iicipants, showed the most improvement in
the Cribnotes system, and were also the primary respondents to the post-survey at 22.
Age Groups 20-34 and 35-49 increased performance scores in Cribnotes by 17-19%, and
were also the primary respondents to the post-survey at 12-14. While the Age Group 50-
64 increased performance scores were representative of fewer patiicipants, their
performance scores increased by 20-22%, and were the least responsive to the post
survey comments at 7.
Lastly, a more detailed representation of the study population's results at an individual
level are repmied on in Table 12. This table contains individual based perfonnance scores
relative to both information systems, as well as, multi-tiered specifics of the linked
comments at the sub-levels associated by positive and/or negative connotations. The
purpose of this table is to clearly represent how the sub-comments and associated sub
codes can impact the qualitative analysis outcomes of the study. Put simply, there can be
multiple sub-comments derived from lengthy survey comments that are represented by
multiple codes. These numeric counts in association with there positive or negative
connotations are compared with the performance scores in order to evaluate the
associations between the objective and subjective results by individual. From the results
the negative codes far outweigh the positive codes in terms of count. Further, regardless
of the positive and/or negative cmmotations represented, 63, or 91.3%, of the study
participants realized a positive increase from MAK performance scores to Cribnotes
performance scores. Only 6 study participants noticed a decreased performance score on
Cribnotes when compared with MAK. Upon investigation, these 6 accounted for a
combined 6 positive codes and 20 negative codes out of the total 120 representative
codes.

VIII. Discussion
This section will first utilize the results found in order to discuss the study variables and
how they relate to the outcomes of the four hypotheses and research questions. Second,
the implications of the study findings associated with policy, theory, overall methodology
to include limitations, and management will be addressed. Third, the study's contribution
to research literature and future research opportunities are reviewed.
The three research questions for which this study seeks to provide answers are as follows:
1) Will RN historic system performance be a better predictor of future system use than
utilizing their attitude, or behavioral intention to use it? 2) Will RN historic system
performance work in conjunction with RN behavioral intentions to explain more R
squared variability together, rather than independently? 3) Were clinical, social, and/or
technical factors identified that can be added as subjective variables to enhance future
analysis ofR squared findings related toRN performance? IS prediction models have
been applied to healthcare settings in an effort to measure adoption, diffusion, and
acceptance ofEHR teclmologies. The TAM was utilized due to its presence in ten percent
of all information systems publications, with thi1iy to forty percent of IT acceptance
attributed to reviews ofthe basic theory (Holden, 2010). The TAM theory thus has a
proven track record in terms of theoretical constructs with which to measure and use in
testing hypotheses. However, the TAM, at its core, primarily focuses on subjective
variables such as perceived ease of use and usefulness to explain technology utilization,
and while useful, this study seeks to test a more objective approach.
66
Results of Hypothesis
Quantitative- Regression Analysis
There were four hypothesis to be tested. Put simply, the intentions of the research were
to assess whether or not the findings related to the addition of the historic objective
performance on the old software would overpower the TAM subjective variables to the
point where TAM was not worthwhile to perform, or if it would be additive in making
the TAM more powerful. Fmiher, these variables were expected to explain all variability
in current performance on the new software. The stated hypotheses are as follows: 1) H1:
The MAK objective nursing performance score will be the primary predictor, or will have
the most impact, on the Cribnotes objective nursing performance score when compared
individually with all other subjective RN behavioral intentions; 2) H2: The MAK
objective nursing performance score will be the primary predictor, or will have the most
impact, on the Cribnotes objective nursing performance score when compared with all
other subjective RN behavioral intentions in aggregate; 3) H3: The MAK objective
nursing performance score will work in conjunction with RN behavioral intentions to
create a more explanatory framework; and 4) H4: The full model consisting ofMAK
objective nursing performance score and the pre-implementation subjective RN
behavioral intentions will describe all the variation in the dependent variable, Cribnotes
objective performance score. Quantitative analysis consisting of linear regression
analysis was utilized to evaluate Hypotheses 1, 2, 3, and 4. In addition, qualitative
analysis consisting of content analysis was utilized to fu1iher evaluate Hypothesis 4.
67
From the quantitative regression analysis, the independent variables of interest measured
against the dependent variable, Cribnotes performance score, consist of the following: 1)
MAK objective use performance score; 2) Pre-MAK perceived ease of use; 3) Pre-MAK
perceived usefulness; 4) Pre-Cribnotes perceived ease of use; 5) Pre-Cribnotes perceived
usefulness; and 6) Post-Cribnotes experience. The coefficient on Pre-MAK objective
performance score was statistically significant at p= .037 (p<.05). This coefficient of .298
indicates that as the number ofPre-MAK objective performance scores increase by one,
the number ofCribnotes objective performance scores increases by 29.8%. The
coefficient on Pre-MAK perceived ease of use was statistically insignificant at p= .903.
This indicates that the nurses who perceive the software as easy to use perform no
differently when measured objectively. The coefficient on Pre-MAK perceived
usefulness was statistically insignificant at p= .11 7. This indicates that the nurses who
perceive the software as useful performed no differently when measured objectively. The
coefficient on Pre-Cribnotes perceived ease of use was statistically significant at p= .019
(p<.05). This coefficient of .153 indicates that the nurses who perceive the software as
easy to use, perform better on Cribnotes objective performance score by an increase of
15.3%. The coefficient on Pre-Cribnotes perceived usefulness was statistically
insignificant at p= .148. This indicates that the nurses who perceive the software as useful
perform no differently when measured objectively. Lastly, the coefficient on Cribnotes
Experience was statistically insignificant at p= .833. This indicates that nurses with
different experience levels with Cribnotes perform no differently when measured
objectively.
68
As it relates to the hypotheses, the statistically significant coefficient of .298 for MAK
objective performance score suggests that if nurses performed well in the MAK system,
then they will perform even better in the Cribnotes system. Thus, high performers in
MAK will surely be high performers in Cribnotes. Those users who were mid performers
in MAK will most likely perform higher in Cribnotes. This predictor was the strongest
individually and in aggregate as Hypothesis 1 and 2 suggest. Thus, these hypotheses are
accepted (Table 13). The coefficient for Pre-Cribnotes perceived ease of use is
statistically significant at .153, and is thus in alignment with the traditional TAM theory
that suggests if a user perceives a system to be easy to use, than that will be a strong
predictor of actual system use. Thus, this variable can be considered as having a positive
impact on the Cribnotes Performance Score, albeit 15.3% in comparison to the 29.8% of
the MAK objective perfonnance score. Note that this variable was reverse coded for
clarity due to the negative connotation when considering nursing responses to the pre
survey question, "Expectation that Cribnotes will increase your nursing workload." In
this case, when the nurses agreed, they had actually disagreed with the respective TAM
variable ease of use. In addition, Hypothesis 3 was accepted because the TAM model
represented by Pre-Cribnotes Ease ofUse, is made much stronger, and thus explains
more variance, tlu·ough the additive presence ofMAK objective performance scores
(Table 13). When these two variables are investigated more closely, the nurses who
perceived the software as easy to use, with the exception of one, also displayed MAK
performance scores ranging from 50%-66%, which is above both the mean and high end
of the standard deviation. This suggests that MAK performance scores may be
69
influencing future perceptions related to ease of use for the Cribnotes application, thus
further strengthening the MAK performance score construct. Lastly, the statistically
significant (p=.023) full regression model yielded the following: R= .481; R squared=
.231; and adjusted R squared= .146. The R value was used to indicate the strength of the
association between the six independent variables at 48.1 %. The R squared value
represents the propmiion of variance in the Cribnotes performance score, explained by
the independent variables at 23.1 %. The Adjusted R square value corrects for positive
bias and estimates effect size equals .146, or 14.6%. When adjusted, the independent
variables account for 14.6% of variation in the dependent variable, Cribnotes
performance score. Thus, Hypothesis 4 is rejected because there was still 85.4%
unexplained variability in the Cribnotes performance score (Table 13). In order to try to
address the remaining 85.4% variability from the quantitative analysis, a qualitative
content analysis was performed.

Qualitative- Content Analysis
From the qualitative content analysis results, derived specifically by the post-
implementation survey comments, the mid-level and high-level categories revealed
applicable findings directly associated with Hypothesis 4. Overall, clinical and IT
comments that were positive totaled 22, or 18.3%, while the negative comments totaled
71
98, or 81. 7%. The 1 :3 ratio of positive to negative responses represents roughly half of
the study pruiicipants. Each high level category is discussed in conjunction with its
associated mid-level categories in order to gain a more detailed understanding of the
coding composition.
Positive Clinical and Technical Impacts
In the first high-level category, the frequency of codes related to Overall Clinical Impact
(Positive) resulted in only 10 instances, or 8.3%. This number represents the sum of mid
level categories Clinical Ease of Use and Clinical Quality Improvement. There were only
three instances after having used both software applications where nursing felt like it was
easy to use. Further, only seven felt like the software applications were useful in the areas
of quality improvement and compliance. These results are in alignment with the rejection
of Hypothesis 4 as the Overall Clinical Impact (Positive), represented 8.3% of all coded
comments collected.
In the second high-level category, the frequency of codes related to Overall IT Impact
(Positive) resulted in 12 instances, or 10%. This number represents the sum of mid-level
category of Application Specific, with zero coded results related to IT Infrastructure. In
this case, there were only twelve approvals for the softwru·e, five of which were for MAK
and seven of which were for Cribnotes.
72
Negative Clinical and Technical Impacts
In the third high-level category, the frequency of codes related to Overall Clinical Impact
(Negative) resulted in 31 instances, or 25.8%. This number represents the sum of mid
level categories Clinical Impact, Teaching Impact, and Clinical Workflow Dependencies.
There were twenty three instances where nurses felt like chmiing workload, timeliness,
and time trouble-shooting IT problems negatively impacted their clinical duties. Along
the same lines, there were three instances where nurses felt that their ability to teach
parents of neo-natal patients was negatively impacted. Lastly, there were five instances
where nurses expressed concern over clinical workflow dependencies among staff outside
the NICU, pharmacy, and clinical situations that necessitated system over-rides. As
Hypothesis 4 was rejected, a portion of the remaining 85% variability may very well be
explained by measuring these three mid-level categories. Further investigation as to the
negative impact they may be having on existing full model regression variables or the
possible addition of them to the regression model may be warranted.
In the fourth high-level category, the frequency of codes related to Overall IT Impact
(Negative) resulted in 67 instances, or 55.8%. This level represents the sum of mid-level
categories Application Specific and IT infrastructure. There were fourteen instances
where nurses did not like the MAK and Cribnotes functionality, lack of integration,
thorouglmess, and system missing information. There were fifty-three instances of IT
Infrastructure where the nurses complained of computer response times, access
timeliness, system instability, associated downtime implications, infrastructure software
configurations, and system inadequacy. This mid-level category alone comprised of 44%
73
of the total coded category frequencies. As Hypothesis 4 was rejected, a portion of the
remaining 85% variability will most likely be explained by measuring these two mid
level categories. There is an obvious workflow barrier in the area ofiT Infrastructure that
needs to be addressed. Further investigation as to the negative impact these may be
having on existing full model regression variables and the possible addition of them to
the regression model may be warranted.
Major Implications
The three research questions addressed by this study are as follows: 1) Will RN historic
system performance be a better predictor of future system use than utilizing their attitude,
or behavioral intention to use it? 2) Will RN historic system performance work in
conjunction with RN behavioral intentions to explain more R squared variability together,
rather than independently? 3) Were clinical, social, and/or teclmical factors identified that
can be added as subjective variables to enhance future analysis ofR squared findings
related to RN performance? Each question has been addressed and can be answered with
a "yes," in that research questions 1 and 2 are positively supported by the results from the
quantitative regression analysis, and question 3 is supported by the qualitative content
analysis results. The implications of these answers contribute to health services research
areas of policy, theory, management, and methodologies in a number of ways, as
described next in the study.
74
Policy Implications
For more than a decade, the theme of improved patient safety and quality of care in the
United States healthcare system has been a common thread in healthcare policy decision:..
making and overall strategy. Specifically, the on-going push for the implementation and
meaningful use of EHRs continue to become more of a reality and are strongly supported
by the federal govermnent. EHRs as a fundamental component in the patient safety and
quality of care movement will not only provide an electronic medium for what in the past
was a paper based system, but have the potential to fundamentally change the workflows
and practices of clinical end users. For these reasons, the importance of understanding
how to become successful users of technology across the healthcare spectrum has never
been greater.
With these points in mind, the results of this study and proposed framework suggest that
policy makers whom support the need for improved quality of care through the
implementation of EHRs need to strongly consider the TAM in conjunction with prior
system performance by clinicians at an individual, departmental, and ultimately
organizational level, as a benchmark by which to predict the timing for requiring greater
quality based metrics and enforcing them through future system enhancements. In other
words, there will have to be a measureable balance by which policy makers decide to
increase quality of care standards that an organization can reasonably meet. For example,
if a large percentage ofhealthcare organizations across the United States are performing
well on properly utilizing the EHR and achieving quality standards, then it may be time
to implement higher quality standards. These standards would then be captured in future
75
software with reimbursement based quality metrics. This is not to say that the software
the clinician is using is the cause of the quality, but rather it is the medium they are using
to assist with the provision of quality care. So if how one performs on a prior system in
conjunction with how one feels about a future system are a representation of current
quality, and thus indicators of future performance, then it seems that policy makers,
associated software certification boards, third party vendors, healthcare organizations,
and ultimately the end user are all in this together.
Theory Implications
The study results suggest that the TAM, while widely accepted as an explanatory model,
is incomplete. The study's measurement results of the historic objective use performance
score proved to be a more powerful predictor than the TAM model as a whole. In
addition, the data suggests that a portion ofthe study results related to the TAM may be
derived from the end users prior experience on the historic system. The TAM, while still
valuable is greatly enhanced by three times the normal explanatory strength as a
prediction model, when it is used in conjunction with the objective performance score.
With this in mind, the objective performance score should be the new basis of the
prediction model. The TAM should not be completely done away with because it has
proven to be a useful predictor, but it should compliment, or be secondary, to the
objective performance score serving as the primary predictor. In addition, the comments
section that was added to the TAM survey was of great value in identifying other
concerns·that may be directly impacting the TAM, but more impmiantly, the objective
perfonnance score. The TAM, as measured through the data collection survey tool in this
76
study, can be made cyclical in a process improvement fashion in that it can be
administered at any time and has the ability to identify related staff concerns. As
concerns are addressed, and thus interventions take place, the resulting impact can be
checked periodically against the pre-post on-going performance scores. So it seems that
while TAM's value as a prediction variable secondary to objective performance scores is
. valid for new pre-post system implementations, it may better serve as an on-going
process-improvement quality management tool in the areas of clinical and IT workflow
throughout the application's life-cycle working within a software generation. Thus, this
revised model framework allows for continuous measurement in preparation for 1) small
incremental changes in the current generation of software (ie. versions) and also 2) for
complete overhauls (ie. replacing legacy systems, changing vendors, software platform
changes) in new generations of software (Appendix 4- Figure 8).
Management Implications
Implications of this study affect a number of management facets across healthcare
organizations. Administrators, as leaders of the organization, are focused on providing a
good product in the form ofhealthcare services and being paid for those services in order
to remain financially viable. The bottom line for leadership is that reimbursement by
payers represented by State and Federal govermnents, as well as, private third parties, is
going to be increasingly dictated by the quality of care provided to those insured. The
way these payers are going to measure organizational quality will be driven by reports
derived from the actual care provided and documented in EHRs. Put simply, an
organization will only be as good as its data. Therefore, the results of this study are
77
compelling in that a framework with which to measure performance at the individual,
departmental, and organizational levels, on key quality measures is a necessity and
should not be taken lightly. If administrators choose to purchase, implement and attest to
State and Federal governments for incentive payments related to meaningful use in hopes
of not being penalized after 2016 in some cases, then they need to understand how to be
successful with their care providing producers, or end users in this case, accepting the
technology and using it appropriately.
From the perspective of mid-level management, quality management, who is responsible
for reporting on these matters, may find themselves in a conundrum of finger pointing
amongst other mid-managers as they try to harness the necessary data in order to check
the box, so to speak, on mandated quality metrics. In this case, workflow dependencies,
describing how specialized hospital departments must work together to ultimately
perfonn a service, are extremely important. These workflow dependencies between the
direct and indirect providers represented by physicians, nursing staff, ancillary clinical
services, such as Pharmacy, Radiology, and Laboratory, and the IT Department all play
vital roles in the delivery of quality care services. In this study, the impacts of
dependencies on nurses related to Pharmacy, other non-NICU providers, and an unstable
IT infrastructure may be primary reasons nurses are performing less than optimal in some
cases. Alternatively, perhaps these clinical and IT related workflow dependencies are
umelated in terms of current constructs measured and need to be tested within the
framework to quantify ban'iers to greater performance scores. Regardless, the onus of
responsibility for staff performance scores will fall on clinical department managers who
78
manage the provision of the actual care taking place and related documentation in the
EHR. Their staffs individual performance scores, as a component of their departmental
score, will ultimately make up the organizational score. Knowing this, clinical
department managers need to stay abreast of workflow issues by continuing to formally
survey their staff members in order to try and isolate current problems before they are
escalated and directly impact their department's performance score.
Methodology Implications and Limitations
For purposes of this study, the goal was to measure the biggest department in the health
system, which in this case was the NICU, in order to yield a large enough sample size to
run a full prediction model. However, the primary implication to the overall methodology
and also a limitation ended up being the sample size. The sample size began at 146 and
ended at 69 due to a number of constraints. The confines of the study methodology were
such that study pmiicipants data was only utilized if all of the data collection was
obtained. Mem1ing, that an eligible or measureable study participant must have all four of
the data points as follows: 1) Utilized MAK in the past when verifying/administering
breast-milk to an NICU infant; 2) Participated in the pre- implementation survey; 3)
Utilized Cribnotes when verifying/administering breast-milk to ail NICU infm1t; and 4)
Participated in the post-impleni.entation survey. Due to the small sample size a true
prediction model could not be run.
When selecting the base objective performance score to serve as the primary predictor, in
this case represented by MAK as a first generation nursing documentation system, it is
79
key to define and determine what makes an end user good at a system prior to measuring
it. This study used proportional base scores that statistically made sense, but did not have
a thorough understanding of how these base scores were impacted by internal or external
sources prior to and during the use of the MAK system. More specifically, there is a
critical need to know what made the end user either good or bad on the MAK system that
translated into their associated base performance score.
Further, the regression analysis needed more study participants in the sample in order to
improve accuracy. Within the regression analysis the experience of the study pa1iicipants,
or the frequency of times they used the system, was measured related to the Cribnotes
information system but was not performed for the MAK system. The addition of an
experience based independent variable for MAK may have better explained why some
users score higher or perhaps lower within the MAK system based on their experience
level with the system.
Other implications were seen in the descriptive statistics from the study results. These
revealed a homogenous population of nursing staff not just limited to study participants,
but to the depmiment as a whole. The department consists of primm·ily white, female
registered nurses (RNs), holding the same positions as staff nurses, and thus performing
the smne tasks. The ages differed throughout, but were evenly distributed.
Lastly, the data collection tool in the form of a pre-post survey was created and utilized
with a small scale that allowed nurses to only agree or disagree. A like1i scale was
80
actually discussed with the NICU nurse manager and IT Clinical Application Coordinator
prior to the creation, but it was decided to keep it simple in terms of the number of
questions and the possible answers. As stated previously in the hypothesis results, the
question related to ease of use represented by the nurse's expectation that workload
would be increased was phrased in a negative fashion. While it was effective at capturing
data, the responses had to be reverse-coded in order to reflect the ease of use definition
that TAM is based on. The final limitation is that ofthe post-survey comments section. In
an overcompensated effort to allow the users to express themselves outside of the
confines of the survey questions and answer options, the comments section was
comprised of open lines with absolutely no guidance. The resulting comments from
roughly half of the study participants were indeed very open ended, but were qualified
through content analysis into a coded categorical hierarchy to make sense of them. This
actually ended up being very informative and was aforementioned as a recommended
management practice for on-going performance monitoring at the clinical managerial
level.
Contributions to Literature
From the study results, measuring EHR historic objective performance scores of nurses in
the NICU yielded a statistically significant theoretical construct as pmi of a newly
formulated prediction framework that may be utilized at the individual, depmtmental,
orgm1izational, and perhaps even at state and national levels. This framework may also be
applied to other clinical disciplines as well. The identification: of a strong singulm·
quantitative predictor is integral to better understanding teclmology acceptance and
81
ultimately achieving quality goals through the use of the EHR medium. When
considering the TAM framework that is already widely proven and accepted in the
literature, it actually becomes a secondary predictor shadowed by the additive value of
the objective performance. The newly proposed framework would primarily utilize
objective performance as the prediction tool, but also use the TAM as an on-going
process-improvement quality management tool in the areas of clinical and IT workflow
throughout the application's life-cycle working within a software generation. By utilizing
this proposed framework, organizations can continuously measure objective performance
both within and across software generations, while making specific adjustments to
necessary workflow concerns along the way. (Appendix 4- Figure 8).
IX. Conclusions and Recommendations
From the study, Hypotheses 1, 2, and 3 were accepted because the addition of the
objective performance score measurement was the most powerful of all the variables. It
also worked in combination with subjective variables to enhance the TAM. Hypothesis 4
was rejected due to the remaining variability left unexplained by the full model. All
research questions echoed Hypotheses 1-3 and were thus affirmed.
This study measured performance on first and second generation nursing documentation
systems. Knowing that this newly proposed model framework is based on very early
stages of EHR use, there is a definite need and opportunity to measure multiple
generations of clinician performance on multi-generation EHRs into the future.
82
Additional research is necessary to further test the reliability of this proposed framework
both within present and across future EHR generations, as well as, seek out additional
performance specific explanatory construct variables. Clearly, a good stmiing place for
future measurements would be to begin with the concerns identified in the qualitative
results of this study, that include various aspects of workflow dependencies amongst
clinical services, as well as, IT facets such as infrastructure and specific application
functionality. Another opportunity is to investigate experience levels within past and
current generations ofEHRs moving forward is to evaluate whether or not a better
understanding related to the frequency of EHR use has an impact on user performance.
Lastly, when assessing base performance scores with which to measure and predict future
system use, there needs to be a more thorough understanding of what this consists of and
how it is derived. In other words, what made the end users good or bad users of the
technology the first time around and what role if any did management play that may have
had m1 impact.
