BRIEF RESUME OF THE INTENDED WORK
INTRODUCTION
Nosocomial infections are infections that are a result of treatment in a hospital or a
healthcare service unit. Infections are considered nosocomial if they first appear 72 hours
or more after hospital admission or within 30 days after discharge.
Nosocomial infections are commonly transmitted when hospital officials become
complacent and personnel do not practice correct hygiene regularly. Also, increased use of
outpatient treatment means that people who are hospitalized are more ill and have more
weakened immune systems than may have been true in the past. Moreover, some medical
procedures bypass the body's natural protective barriers. Since medical staff moves from
patient to patient, the staff themselves serves as a means for spreading pathogens.
Hospitals have sanitation protocols regarding uniforms, equipment sterilization, washing,
and other preventative measures. Thorough hand washing and/or use of alcohol rubs by all
medical personnel before and after each patient contact is one of the most effective ways
to combat nosocomial infections. More careful use of antimicrobial agents, such as
antibiotics, is also considered vital
In the United States, the Centers for Disease Control and Prevention estimates that
roughly 1.7 million hospital-associated infections, from all types of bacteria combined,
cause or contribute to 99,000 deaths each year. In Europe, where hospital surveys have
been conducted, the category of Gram-negative infections are estimated to account for
two-thirds of the 25,000 deaths each year. Nosocomial infections can cause severe
pneumonia and infections of the urinary tract, bloodstream and other parts of the body.
Many types are difficult to attack with antibiotics, and antibiotic resistance is spreading to
Gram-negative bacteria that can infect people outside the hospital.
In a representative sample of US general hospitals, the authors found that the
establishment of intensive infection surveillance and control programs was strongly
associated with reductions in rates of nosocomial urinary tract infection, surgical wound
infection, pneumonia, and bacteremia between 2000 and 2005–2006, after controlling for
2
other characteristics of the hospitals and their patients. Essential components of effective
programs included conducting organized surveillance and control activities and having a
trained, effectual infection control physician, an infection control nurse per 250 beds, and
a system for reporting infection rates to practicing surgeons. Programs with these
components reduced their hospitals' infection rates by 32%. Since relatively few hospitals
had very effective programs, however, only 6% of the nation's approximately 2 million
nosocomial infections were being prevented in the mid-2000s, leaving another 26% to be
prevented by universal adoption of these programs. Among hospitals without effective
programs, the overall infection rate increased by 18% from 1990 to 2006.
Currently, about 180 hospitals participate in the National Nosocomial Infections
Surveillance (NNIS) system. From January 1980 through April 1998, 127,200 fungal
isolates causing nosocomial infections were reported from these hospitals; Candida
species accounted for 19,621 (72.1%) of these isolates. Immunocompromised patients are
at particularly high risk for candidemia. In patients with acute lymphocytic leukemia,
treatment with vancomycin and/or imipenem appears to be an independent risk factor for
candidemia; colonization of stool by Candida species may be another important
predisposing factor in these patients. Rapid detection of invasive candidemia in these
high-risk patients is particularly important to the improvement of rates of survival.
Methods for rapid detection, such as the measurement of manna (the major cell-wall
polysaccharide of Candida), may be useful for diagnosing invasive candidacies and for
monitoring the response of this infection to antifungal therapy. Further studies of risk
factors and the development of new methods for rapid diagnosis and monitoring should
help decrease the morbidity and mortality associated with nosocomial fungal infections.
A study was conducted to find the incidence of hospital-acquired pneumonia in 1886
consecutive admissions to an 1800 bed hospital in Bombay; 991 of them to general
medical wards and 895 to a 17-bed medical intensive care unit (ICU). The average bed
occupancy in the general wards was 56 patients in a ward with 40 beds. Staffing in the
general ward was two nurses for 56 patients, and in the ICU three nurses for 17 beds. One
hundred and sixty-eight patients developed nosocomial pneumonia: 18 (1·8%) in general
wards and 150 (16·7%) in the ICU. Common isolates included Pseudomonas spp (44%)
and Klebsiella spp (34%). The most frequently used antibiotics were cefotaxime (34%),
3
amikacin (25%), gentamicin (23%) and ofloxacin (13%). Crude mortality in general ward
patients was 88·9 vs. 14·6% in patients without pneumonia. The corresponding figures for
ICU patients were 67·4 vs 37·1%; 40% of the crude mortality in ICU patients with
pneumonia was attributable to the infection. Infected patients stayed an additional 5·8
days in the ICU and 6·7 days in the general ward. Costs of additional stay and antibiotics
accounted for 18·6% of the ICU budget. The incidence of nosocomial pneumonia was
lower than expected, despite occupancy exceeding bed capacity, low nurse:patient ratios,
and extensive reuse of disposable respiratory therapy equipment. Nevertheless,
nosocomial pneumonia imposes a significant financial burden on the already scarce
resources available for intensive care in developing countries like India.
A study included 201 patients (1285 patient days) admitted to RICU over a period of one-
and-a-half years. A total of 77 infections were identified in 67 patients (33.5%). The
infections included pneumonia (23%), sepsis of unknown origin (10.5%), bacteremia
(7.5%), urinary tract infections (1.5%), catheter related blood stream infections (1%) and
Clostridium difficile colitis (1%). The most commonly identified organisms were the
Acinetobacter species (34.8%), Pseudomonas aeruginosa (23.9%) and Escherichia coli
(15.2%). The median length of stay in patients with and without infection was 13 days
(interquartile range, IQR, 28) and 4 days (interquartile range, IQR, 3), respectively
(p<0.0001). Multivariate analysis showed the following risk factors for ICU-acquired
infection: the admitting diagnosis of infection (odds ratio [OR] 3.3; 95% confidence
intervals [CI] 1.06–10.1), length of stay in the RICU (OR, 1.2; 95% confidence intervals
[CI] 1.1–1.33); renal failure (OR, 4.7; 95% CI, 1.52–14.41) and institution of parenteral
nutrition (OR, 16.9; 95% CI, 1.07–269.03). Multivariate analysis showed the following
risk factors for death in ICU: APACHE II scores (OR, 1.06; 95% CI, 1.01–1.11), and
endotracheal intubation (OR, 5.07; 95% CI, 1.24–20.65).
The Norwegian Institute of Public Health initiated a national surveillance system for
nosocomial infections in 2002. The system is based on two annual one-day prevalence
surveys recording the four most common types of nosocomial infection: urinary tract
infections; lower respiratory tract infections; surgical site infections and septicaemia. All
acute care hospitals in Norway (N=76) were invited to participate in the four surveys in
2002 and 2003. The total prevalence of the four recorded nosocomial infections varied
between 5.1% and 5.4% in the four surveys. In all surveys, nosocomial infections were
4
located most frequently in the urinary tract (34%), followed by the lower respiratory tract
(29%), surgical sites (28%) and septicaemia (8%). The prevalence surveys give a brief
overview of the burden and distribution of nosocomial infections. The results can be used
to prioritize further infection control measures and more detailed incidence surveillance of
nosocomial infections.
A one-day survey was carried out in 88 out of 113 public hospitals in Lombardy to obtain
prevalence rates of hospital-acquired infections (HAIs) by hospital departments and to
identify the pathogens more frequently involved. In total 18 667 patients were surveyed,
representing 72% of the average daily total of occupied beds in public hospitals in
Lombardy. The overall prevalence of HAI was 4.9%. The highest prevalence was
observed in intensive care units and in spinal units. The prevalence of bloodstream
infections was 0.6%; pneumonia 1.1%; urinary tract infections 1.6% and gastrointestinal
infections 0.4%. In surgical patients the prevalence of surgical site infections was 2.7%.
The most frequently isolated pathogen from all sites of infections was Escherichia coli
(16.8%), followed by Staphylococcus aureus (15.0%), Pseudomonas aeruginosa (13.2%)
and Candida spp. (8.7%). Methicillin-resistant S. aureus accounted for 23% of all isolated
S. aureus. The results provide baseline data for rational priorities in allocation of
resources, for further studies and for infection control activities.
A retrospective study was undertaken to compare the nosocomial infection rate in obese
and normal weight surgical patients. All patients undergoing general, urologic, vascular,
thoracic, or gynecologic surgical procedures between October 1 and December 31, 1991,
were reviewed. Nosocomial infection data were obtained from the Department of Hospital
Epidemiology. A total of 849 patients were evaluated, of which 536 (63%) were normal
weight (BMI < 27 kg/m2), 175 (21%) were obese (BMI 27-31 kg/m2), and 138 (16%)
were severely obese (BMI > 31 kg/m2). Age, mortality, and American Society of
Anesthesia (ASA) risk scores did not differ among the three groups. There were
significant increases in the number and percent of nosocomial infections in the obese
populations, with rates of 0.05 per cent in normal weight, compared to 2.8 per cent and 4.0
per cent in obese and severely obese groups (P < 0.01). Infections consisted of seven
wound infections, five C. difficile infections, one pneumonia, and three bacteraemia. No
differences in distribution between groups were evident. Mortality was similar among the
groups. These data support the hypothesis that obesity is a significant risk factor for
5
clinically relevant nosocomial infections in surgical patients.
6.1 NEED FOR THE STUDY
Hospital-acquired pneumonia is a growing concern that all nurses need to be aware
of because hospital-acquired infections are a major challenge to patient safety. It is also
estimated that in 2002, a total of 1.7 million hospital-acquired infections occurred (4.5 per
100 admissions), and almost 99,000 deaths resulted from or were associated with a
hospital-acquired infection, making hospital-acquired infections the sixth leading cause of
death. At the same time it is also estimated that approximately one third or more of
hospital-acquired infections are preventable.1
A case-control study was conducted intending to evaluate the influences of
severity of illness and evolution of therapeutic activity on the development of nosocomial
infections, and to estimate the attributable consequences of these infections on ICU
patients. The study concluded that a persistent high level of therapeutic activity and
persistently depressed consciousness on the third day after ICU admission are associated
with the acquisition of nosocomial infection by critically ill patients hospitalized in a
medical ICU. Such nosocomial infections are responsible for excess mortality, prolonged
stay, and increased therapeutic activity independently of the initial severity of illness.
Thus, nosocomial infections exact a heavy toll on all concerned the patient, the medical
staff, and economic resources especially in cases of multiple infections.2
A prospective study was conducted to know the incidence of hospital-acquired
pneumonia in 1886 consecutive admissions to an 1800 bed hospital in Bombay; 991 of
them to general medical wards and 895 to a 17-bed medical intensive care unit (ICU). The
average bed occupancy in the general wards was 56 patients in a ward with 40 beds.
Staffing in the general ward was two nurses for 56 patients, and in the ICU three nurses
for 17 beds. One hundred and sixty-eight patients developed nosocomial pneumonia: 18
(1·8%) in general wards and 150 (16·7%) in the ICU. Common isolates included
Pseudomonas spp (44%) and Klebsiella spp (34%). The most frequently used antibiotics
were cefotaxime (34%), amikacin (25%), gentamicin (23%) and ofloxacin (13%). Crude
mortality in general ward patients was 88·9 vs 14·6% in patients without pneumonia. The
6
corresponding figures for ICU patients were 67·4 vs 37·1%; 40% of the crude mortality in
ICU patients with pneumonia was attributable to the infection. Infected patients stayed an
additional 5·8 days in the ICU and 6·7 days in the general ward. Costs of additional stay
and antibiotics accounted for 18·6% of the ICU budget. The incidence of nosocomial
pneumonia was lower than expected, despite occupancy exceeding bed capacity, low
nurse: patient ratios, and extensive reuse of disposable respiratory therapy equipment.
Nevertheless, nosocomial pneumonia imposes a significant financial burden on the
already scarce resources available for intensive care in developing countries like India.3
According to the most recent statistics from the CDC, hospital-acquired
pneumonia accounts for nearly 15% of all hospital-acquired infections and is associated
with the highest mortality rates (20% to 33%). It's second only to urinary tract infections
as the most common Hospital acquired infections.4
Throughout the world, including Asia, Nosocomial infection is an important public
health problem, often with pneumonia as a significant consequence. Hospital-acquired
pneumonia is associated with significant morbidity and mortality and increased costs of
treatment. Hospital acquired pneumonia is associated with crude mortality rates of up to
70% and attributable mortality rates as high as 33% to 50%. A study conducted in India
showed that the Mortality rates relating to nosocomial pneumonia was 37% to 47.3% and
the Incidence of ventilator associated pneumonia was 8.95 per 1000 ventilator days and
the incidence of hospital acquired pneumonia was 53.9%.5
A study was conducted to identify knowledge deficits concerning nosocomial
pneumonia prevention among critical care nurses. A survey design using a mailed self-
administered questionnaire was used. A sample of 134 critical care nurses was included in
the study. The results showed that nurse practioners knowledge score ranged from 21% to
92%. The mean (and median) was 48%. Items related to knowledge about nosocomial
risks had the highest mean score (67%) compared to items addressing nosocomial
pneumonia prevention (43%) or the role of devices in the transmission of NP (45%). No
nurse demographic or workplace characteristic was associated with nosocomial
pneumonia knowledge. The study concluded that nurse practioners knowledge score
ranged from 21% to 92%. The mean (and median) was 48%. Items related to knowledge
about nurse practioners risks had the highest mean score (67%) compared to items
addressing nurse practioner prevention (43%) or the role of devices in the transmission of
7
nurse practioner (45%). No nurse demographic or workplace characteristic was associated
with nurse practioner knowledge.6
A study was conducted to evaluate the extent to which nurses working in intensive
care units implement best practices when managing adult patients receiving mechanical
ventilation. Nurses attending education seminars in the United States completed a 29-item
questionnaire about the type and frequency of care provided. Twelve hundred nurses
completed the questionnaire. Most (82%) reported compliance with hand-washing
guidelines, 75% reported wearing gloves, half reported elevating the head of the bed, a
third reported performing subglottic suctioning, and half reported having an oral care
protocol in their hospital. Nurses in hospitals with an oral care protocol reported better
compliance with hand washing and maintaining head-of-bed elevation, were more likely
to regularly provide oral care, and were more familiar with rates of ventilator-associated
pneumonia and the organisms involved than were nurses working in hospitals without
such protocols. The study concludes that guidelines for the prevention of ventilator-
associated pneumonia from the Centers for Disease Control and Prevention are not
consistently or uniformly implemented.7
A prospective study was conducted to determine the epidemiology for
postoperative nosocomial infections. The study concludes that Nosocomial pneumonia
with resistant gram-negative bacteria now predominates along with increased incidence of
fungal infections. Currently, postoperative infections are now more severe, involve critical
organs, and require close monitoring of the changing patterns of pathogens.8
Hospital-acquired pneumonia and ventilator-associated pneumonia are significant
public health issues in Asian countries, as they are worldwide. Mortality attributable to
hospital acquired pneumonia and especially ventilator associated pneumonia is very high.5
Hence the investigator strongly feels that there is a need for conducting a structured
teaching programme on prevention of nosocomial pneumonia.
6.2 REVIEW OF LITERATURE
Review of literature refers to activities involved in identifying and searching for
information on a topic and developing and understanding the state of knowledge on the
topic .researcher never conduct a study in intellectual vacuum their studies are usually
8
undertaken within the context of an existing basic knowledge
The literature is reviewed and presented under the following headings
1. Studies related to incidence of nosocomial infection
2. Studies related to nosocomial infection
3. Studies related to nurses knowledge on nosocomial infection
4. Studies related to structured teaching programme
1. Studies related to incidence of nosocomial infection
A study was conducted to find out the incidence of nosocomial infection, It’s
found that the incidence of pneumonia was identical with ventilator circuit changes every
48 h and with no ventilator circuit changes. The study prospectively assessed whether
keeping ventilator circuits clean with a heat and moisture exchanger exhibiting
antimicrobial barrier properties affects patient colonization and the incidence of
nosocomial pneumonia in patients receiving mechanical ventilation for more than 48 h.
Consecutive patients were randomly allocated to humidification with either a heat and
moisture exchanger (Group 1, n = 61) or a heated humidifier (Group 2, n = 70). In both
groups, no circuit changes were performed throughout ventilatory support. Duration of
mechanical ventilation was identical in both groups (10 +/- 8.6 d (range: 2 to 47) in Group
1 and 12.5 +/- 14.2 d [range: 2 to 85] in Group 2). The incidence of pneumonia (positive
quantitative culture of protected brush specimen) was similar in both groups (6/61 and
8/70 in Groups 1 and 2, respectively; p = 0.8), as was duration of ventilation prior to
pneumonia (9 +/- 5.9 versus 8.2 +/- 5.7 d; p = 0.8). Ventilator tubing contamination was
considerably reduced with the use of a heat and moisture exchanger. In contrast, bacterial
colonization of the pharynx and trachea was identical in both groups. These results suggest
9
that circuit colonization plays little or no role in the occurrence of ventilator-associated
pneumonia, provided usual maintenance precautions are applied (50)
A retrospective study was carried out to determine the current status of nosocomial
infection in China between 2003 and 2007. Nosocomial infections were defined according
to the definitions of Centers for Disease Control and Prevention. The overall patient
nosocomial infection rate, the incidence density rate of nosocomial infections, the excess
length of stay, and distribution of nosocomial infection sites were determined. Among
1980 patients admitted over the period of time, the overall patient nosocomial infection
rate was 26.8% or 51.0 per 1000 patient days., Lower respiratory tract infections (LRTI)
accounted for most of the infections (68.4%), followed by urinary tract infections (UTI,
15.9%), bloodstream (BSI, 5.9%), and gastrointestinal tract (GI, 2.5%) infections. There
was no significant change in LRTI, UTI and BSI infection rates during the 5 years.
However, GI rate was significantly decreased from 5.5% in 2003 to 0.4% in 2007. In
addition, A. baumannii, C. albicans and S. epidermidis were the most frequent pathogens
isolated in patients with LRTIs, UTIs and BSIs, respectively. The rates of isolates resistant
to commonly used antibiotics ranged from 24.0% to 93.1%. The study concluded that
there was a high and relatively stable rate of nosocomial infections in the ICU of a tertiary
hospital in China through year 2003–2007. Guidelines for surveillance and prevention of
nosocomial infections must be implemented in order to reduce the rate of infection.12
A study was conducted on 48 ventilated patients with nosocomial pneumonia identified on
the basis of results of protected specimen brush quantitative culture and identification of
intracellular organisms in cells recovered by bronchoalveolar lavage. For matching cases
and their respective controls, the following variables were used: age (± 5 years),
Simplified Acute Physiologic Score (± 3 points), indication for ventilatory support, date of
admission, and duration of exposure to risk.Successful matching was achieved for 222 of
240 (92.5%) variables. The mortality rate in cases was 26 of 48 (54.2%) compared with
13 of 48 (27.1%) in controls. The attributable mortality was 27.1% (95% confidence
interval [CI], 8.3% to 45.9%; p < 0.01) and the risk ratio for death was 2.0 (95% CI, 1.61
to 2.49). The mean length of stay was 34 days for cases and 21 days for controls (p <
0.02). In the case of pneumonia due to Pseudomonas or Acinetobacter species, the
mortality rate was 71.4%, the attributable mortality was 42.8% (95% CI, 14.5% to
10
69.0%), and the risk ratio was 2.50 (95% CI, 1.31 to 4.61). Pneumonias occurring in
ventilated patients, especially those due to Pseudomonas or Acinetobacter species, are
associated with considerable mortality in excess of that resulting from the underlying
disease alone, and significantly prolong the length of stay in the intensive care unit.(51)
2. studies related to nosocomial infection
A study was conducted to define the prevalence, risk factors, spectrum of
organisms and sensitivity patterns, and the outcome in patients with severe hospital
acquired pneumonia (HAP) in the Medical Intensive Care Unit (SCU) in a hospital in
Singapore. Consecutive patients admitted to the MICU over a 6-month period were
studied and assessed daily to determine whether patients had developed HAP based on
defined clinical criteria. Sputum or endotracheal aspirate was obtained and results
recorded from each patient on admission and every subsequent three days throughout the
stay in the MICU. Mortality during hospital stay was the main outcome measure recorded.
A total of 136 patients (150 admissions) were studied; 24 patients were identified as
having HAP. The prevalence of HAP was 17%. The spectrum of organisms which caused
HAP were polymicrobial, Klebsiella pneumoniae, Pseudomonas aeruginosa, methicillin-
resistant Staphylococcus aureus and coagulase negative Staphylococcus. The mortality of
patients with VAP and HAP were 72.7% and 76.9% respectively. The study concludes
that HAP in the MICU is common with a high mortality. The spectrum of organisms was
comparable to previous studies.9
A prospective study to define how many and what kind of nosocomial infections
are occurring, what are the causative microbes and what kind of drugs can be used in
treatment of infection at Al-Hada Armed Forces Hospital, Taif, Saudi Arabia during the
year 2004. Determination of nosocomial infections was performed using standardized
11
CDC criteria. A total of 1382 patients had developed infection during hospital admission
and were included in the study. Of them, 668 (48.3%) had nosocomial infection and 714
(51.7%) had community-acquired infection. Among those who developed nosocomial
infections, 216 (32.3%), 172 (25.7%) and 124 (18.6%) had respiratory tract (RTI), urinary
tract (UTI) and blood stream infections (BSI) respectively. Surgical site infection (SSI)
was reported in 86 cases (12.9%). Gram-positive organisms were reported in 31.8%.
MRSA (Methicillin-resistant S. aureus) was the commonest (10.2%), followed by
coagulase negative staphylococci (8.5%) and MSSA (Methicillin-susceptible S. aureus,
7.4%). While Gram-negative organisms were reported in 66.2%, E. coli was the
commonest (22.3%), followed by Pseudomonas aeruginosa (17.6%) and Klebsiella
pneumoniae (9.9%). Acinetobacter spp. and MRSA were highly sensitive to Imipenem
(88.6%) and Vancomycin (98.5%) respectively. E. coli were highly sensitive to most of
the antimicrobial agents except ampicillin (26.6%). The study concluded that Pneumonia,
urinary tract infections, and blood stream infections made up the great majority of
nosocomial infections.10
A study was conducted to determine the epidemiology, microbial etiology, risk
factors and clinical manifestations of HAP and VAP. The study concludes that Hospital-
acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) are important
causes of morbidity and mortality, with mortality rates approaching 62%. HAP and VAP
are the second most common cause of nosocomial infection overall, but are the most
common cause documented in the intensive care unit setting. In addition, HAP and VAP
produce the highest mortality associated with nosocomial infection. Thus prevention and
risk-reduction strategies to reduce the risk of acquiring these infections were collated.
Future initiatives to enhance more rapid diagnosis and to effect better treatment for
12
resistant pathogens are necessary to reduce morbidity and improve survival.11
A prospective cohort study was conducted over 18 months in five intensive care
units to determine if Pneumonia is a very common nosocomial infection in intensive care
units (ICUs). The results showed that among the 1,876 patients who were admitted a total
of 158 patients developed nosocomial pneumonia. The main risk factors for nosocomial
pneumonia were elective surgery, emergency surgery, usage of a nasogastric tube, and
mechanical ventilation. Nosocomial pneumonia prolonged the length of ICU stay but was
not directly associated with a fatal outcome. The study concluded that more studies using
competing risk models, which provide more accurate data compared to naive survival
curves or logistic models, should be carried out to verify the impact of risk factors and
patient characteristics for the acquisition of nosocomial infections and infection-associated
mortality.13
A case- control study was performed in order to confirm that re-intubation can be
a risk factor of nosocomial pneumonia in mechanically ventilated patients. Forty
consecutive patients needing re- intubation were selected as cases. Each case was paired
with a matched control for the previous duration of mechanical ventilation. The results
showed that 47% of the cases developed pneumonia after re-intubation compared with
10% of the controls. Regression analysis demonstrated that re-intubation was the only
significant factor related to the development of pneumonia. The results also showed that
semirecumbency during the period between extubation and re-intubation may play a role
in nosocomial pneumonia development in patients who need re-intubation. Mortality rate
were also higher in re-intubated patients when compared with controls. The study
concludes that re-intubation is a risk factor for ventilator-associated pneumonia and might
13
be avoided in a substantial number of cases.14
A study was conducted to identify the several ways to prevent ventilator-
associated pneumonia in patients on a ventilator, according to researchers who analyzed
the medical literature on this topic. Effective methods include raising the patients head to
a 45-degree angle, using sucralfate instead of H(sub 2)-blockers to prevent stress ulcers,
and suctioning the throats of patients who are on a ventilator for more than three days. On
the other hand, changing ventilator circuitry or filters frequently did not lower the risk of
pneumonia.15
A study to evaluate that continuous aspiration of throat secretions may reduce the
incidence of ventilator-associated pneumonia. Pneumonia is common among
mechanically ventilated patients, occurring when bacteria enter the lungs through the cuff
of endotracheal tubes. Of 153 patients receiving mechanical ventilation with the same
kind of tube, 76 also received continuous aspiration (suction) of secretions from below the
voice box and 77 did not (control group). Fourteen (18.4%) of the patients receiving
aspiration developed pneumonia, versus 25 (32.5%) of the control patients. Pneumonia
developed later on average in the aspiration group than in the control group (12 days vs
six days). Analysis of the aspirated secretions revealed microorganisms that often cause
ventilator-associated pneumonia, suggesting that suctioning these secretions can help
prevent the bacteria from entering the endotracheal tube, thus reducing the risk of
pneumonia.16
A prospective study of 213 patients admitted to a medical intensive care unit was
done to determine the frequency of colonization of the respiratory tract with Gram-
negative bacilli and the relation of such colonization to nosocomial infection. Ninety-five
14
patients (45%) became colonized, 22% on the first hospital day. Associated with
colonization were respiratory tract disease, coma, hypotension, tracheal intubation,
acidosis, azotemia, and either leukocytosis or leukopenia. Antimicrobial therapy may have
promoted colonization in some patients. Nosocomial infections developed in 26 patients
(12.2%), 22 of whom were colonized with Gram-negative bacilli. Nosocomial respiratory
infections occurred in 23% of colonized patients but in only 3.3% of noncolonized
patients. The study concludes that control of nosocomial pneumonia may require the
development of methods for preventing or interrupting the colonization of hospitalized
patients with Gram-negative bacilli.17
A prospective, randomized, case-controlled clinical trial was conducted to assess
the effectiveness of 0.12% chlorhexidine gluconate oral rinse in decreasing microbial
colonization of the respiratory tract and nosocomial pneumonia in patients undergoing
open heart surgery. (0.12% chlorhexidine gluconate) was the experimental drug, and
Listerine (phenolic mixture) was the control drug. A total of 561 patients undergoing
aortocoronary bypass or valve surgery requiring cardiopulmonary bypass were
randomized to an experimental (n = 270) or a control (n = 291) group. Nosocomial
pneumonia was diagnosed by using the criteria established by the Centers for Disease
Control and Prevention. The results showed that The overall rate of nosocomial
pneumonia was reduced by 52% in the Peridex-treated patients. The incidence rate of
nosocomial pneumonia was 71% lower in the Peridex group than in the Listerine group.
The study concludes that although rates of nosocomial pneumonia were lower in patients
treated with Peridex than in patients treated with Listerine, the difference was significant
only in those patients intubated more than 24 hours who had the highest degree of
bacterial colonization.18

3. Literatures related to nurses knowledge on nosocomial infection
A study was conducted to identify whether nosocomial infections can lead to
complications in the patients admitted to neurosurgery intensive care units. The most
common causes were ventriculitis, shunt infections, meningitis, surgical wound infections,
urinary tract infections, pneumonia, intravascular catheter related to infections and
gastrointestinal infections. The results showed that In order to reduce infection rates it is
useful to inform intensive care nurses about the infection sources and it is useful to change
their behaviours. The study concludes that Infection control measures are to be viewed as
priority and have to be integrated fully into the continuous process of improvement of
quality of care.19
A study was conducted by using a validated multiple-choice questionnaire, developed to
evaluate nurses' knowledge of VAP prevention. The questionnaire was distributed and
collected during the annual congress of the Flemish Society for Critical Care Nurses .638
questionnaires were collected (response rate 74.6%). Nineteen percent of the respondents
recognized the oral route as the recommended way for intubation. It was known by 49%
of respondents that ventilator circuits should be changed for each new patient. Heat and
moisture exchangers were checked as the recommended type of humidifier by 55% of
respondents, but only 13% knew that it is recommended to change them once weekly.
Closed suctioning systems were identified as recommended by 17% of respondents, and
20% knew that these must be changed for each new patient only. Sixty percent and 49%,
respectively, recognized subglottic drainage and kinetic beds to reduce the incidence of
VAP. Semi-recumbent positioning is well known to prevent VAP (90%). The average
knowledge level was higher among more experienced nurses (> 1 year experience) and
those holding a special degree in emergency and intensive care. They concluded that
Nurses lack knowledge regarding recommendations for VAP prevention. Nurses'
schooling and continuing education should include support from current evidence-based
guidelines 20
4. literatures related to structured teaching programme
A study was conducted over a four month period, on one surgical ward of a large general
hospital. A total of forty subjects met the criteria of the study, and their informed consent
was obtained. The first twenty subjects were assigned to the control group, and received
the unstructured, pre-existing preoperative instruction from the staff nurses. The second
16
twenty subjects made up the experimental group and received structured preoperative
teaching in small groups conducted by the investigator, with the aid of a slide-taped
programme developed specifically for the study. Prior to discharge, each subject was
given two questionnaires to complete, and data were collected by means of a patient
profile sheet. The two groups of subjects were found to be similar when compared on
selected characteristics. The alternative hypotheses of the study were analyzed by means
of a t-test, and chi square test at the .05 level of significance. The results revealed no
significant effect of the structured preoperative teaching programme upon the adult
surgical patient's length of hospital stay, postoperative complications, and number of
analgesics administered postoperatively, or the degree of satisfaction attained from the
preoperative teaching he received. However, statistical significance was found for the
patient's ability to recall knowledge explained preoperatively. Implications of this study
and recommendations for future research were also suggested.21
A study was conducted to find out the effectiveness of structured teaching program in
improving knowledge and attitude of school going adolescents on reproductive health.
Selected schools with similar settings in Dharan town of Nepal. All the subjects were
divided into two groups experimental and control, each comprising of two subgroups of
50 boys and 50 girls. Structured teaching program consisting of information on human
reproductive system was used as a tool of investigation for the experimental group,
whereas conventional teaching method was used for the control group.22
A total of 200 Adolescent school students were included in this study. The mean (±SD)
pretest score of the experimental group on knowledge of reproductive health was 39.83 (±
16.89) and of the control group was 39.47(±0.08). The same of experimental group after
administration of the structured teaching program (84.60±10.60) and of the control group
with conventional teaching method (43.93±10.08) was statistically significant
(p<0.001).Similarly, the post-test scores of knowledge of the groups on responsible sexual
behaviour and their attitude towardsreproductive health were better in the experimental
group than in the control group (p<0.001). They Concluded: The knowledge of adolescent
school students on reproductive health is inadequate. The use ofstructured teaching
program is effective in improving knowledge and attitude of the adolescents on
reproductive health.
This experimental study was designed to determine the effectiveness of a structured
preoperative teaching programme for the adult surgical patient as measured by several
17
indicators. The major questions asked in this study were: What are the effects of a
structured preoperative teaching programme upon the adult surgical patient's length of
hospital stay, postoperative complications, number of analgesics administered
postoperatively, recall of knowledge explained preoperatively, and satisfaction with his
preoperative teaching. 23
