Anesthesiologist to Patient CommunicationA Systematic ReviewMichael J. Tylee, MD; Gordon D. Rubenfeld, MD, MSc; Duminda Wijeysundera, MD, PhD; Michael C. Sklar, MD; Sajid Hussain, MD; Neill K. J. Adhikari, MD, MSc
Abstract
IMPORTANCE Many patients are admitted to the intensive care unit following surgery, and some ofthem will experience incomplete recovery. For patients in this situation, preoperative discussionsregarding patient values and preferences may direct care decisions. Existing literature shows that itis uncommon for surgeons to have these conversations preoperatively; it is unclear whetheranesthesia professionals engage with patients on this topic prior to surgery.
OBJECTIVE To review the literature on communication between patients and anesthesiaprofessionals, with a focus on discussions related to postoperative critical care.
EVIDENCE REVIEW MEDLINE and Web of Science were searched using specific search criteria fromJanuary 1980 to April 2020. Studies describing encounters between patients and anesthesiaprofessionals were selected, and data regarding study objectives, study design, methodology,measures, outcomes, patient characteristics, and clinical setting were extracted and collated. ThePreferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelinewas followed.
FINDINGS A total of 12 studies including 1284 individual patient encounters were eligible forinclusion in the review. These studies demonstrated that communication between patients andanesthesia professionals related to postoperative care is rare: only 2 studies reported communicationregarding adverse postoperative events, and this communication behavior was reported in only 46of 1284 consultations (3.6%) across all studies. Additional findings were that communication duringthese encounters is dominated by anesthetic planning and perioperative logistics, with variablediscussion of perioperative risks vs benefits and infrequent elicitation of patient values andpreferences. Some data suggest that patients wish to be involved in perioperative decision-makingbut are often limited by an incomplete understanding of risks and benefits.
CONCLUSIONS AND RELEVANCE This systematic review found that communication in anesthesiais dominated by anesthetic planning and discussion of preoperative logistics, whereas postoperativecritical care is rarely discussed. Most patients who are admitted to an intensive care unit after a majoroperation will not have had a discussion regarding goals of care specific to protracted recovery orprolonged intensive care with their anesthesiologist.

Introduction
Communication with patients about therapeutic options and care plans is a critical component ofshared decision-making and is particularly important when a decision may result in a major orpermanent change in a patient’s health status. This situation is relatively common for patientsundergoing major surgery. Surgeons and anesthesiologists are the principal clinicians with the
Key PointsQuestion Do anesthesiologists or other
anesthesia professionals engage in
discussions with patients regarding
decisions with implications beyond the
operating room?
Findings In this systematic review of
the literature on communication
between patients and anesthesia
professionals, limited data were found
on communication regarding
perioperative decisions with
implications that reach beyond the
operating room. These data suggest that
communication between patients and
anesthesia professionals during
preoperative encounters is dominated
by discussion of anesthetic planning and
perioperative logistics, with variable
discussion of risks vs benefits and
infrequent discussion of postoperative
care or elicitation of patient values and
preferences.
Meaning These findings suggest that
patients who become critically ill
following scheduled surgical
interventions are unlikely to have had
discussions with their anesthesiologist
regarding values and preferences for
navigating complex postoperative care
decisions, such as prolonged invasive
ventilation, protracted hospital stay with
incomplete recovery, or end-of-life care.

opportunity and, arguably, the responsibility to elicit values and preferences about postoperativecare from surgical patients to inform care decisions if patients become critically ill and lose decisionalcapacity postoperatively. Previous work suggests that surgeons uncommonly elicit patientpreferences regarding postoperative critical illness preoperatively, even for high-risk patients.1,2
Anesthesiologists also have the opportunity to elicit patient values and preferences preoperatively,and some members of the specialty have an interest in expanding anesthesiologists’ role inperioperative medicine.3-5 Knowledge and communication of medical and surgical complicationsafter surgery, as opposed to complications of the anesthetic, are essential to this role. However, theextent of anesthesiologists’ responsibility and their ability to perform this role is not clear, and thereare likely variable professional expectations for patient-anesthesiologist communication in differenthealth care systems and settings.
There are few data on communication during anesthesia consultations. Although studies onanesthesiologist-patient communication have been narratively reviewed,6,7 there is no systematicreview on this topic. In this review, a systematic search strategy was used to extract and collate dataon communication between anesthesia professionals and patients, and the methodological qualityof existing studies was assessed. A synthesis of the data focused on communication aboutpostoperative critical illness is presented.
Methods
A systematic review of the literature on communication between anesthesia professionals andpatients was performed to address the following question: in preoperative anesthetic encounters,what are the patterns and content of communication between anesthesia professionals and patientsas evaluated by qualitative or mixed methods? Reporting is consistent with the Preferred ReportingItems for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline.8
Information Sources and SearchA MEDLINE search was performed (from 1980 to April 2020) to retrieve any studies with a focus oncommunication between patients and anesthesia professionals (eAppendix 1 in the Supplement). A1-generation, forward-and-backward search on Web of Science was then performed using each of theincluded studies from the MEDLINE search to identify additional relevant studies.
Study Eligibility, Selection, and Data ExtractionOnly studies with data describing specific encounters between patients and anesthesia professionalswere included. Studies with a primary focus other than communication, studies on communicationduring anesthesia procedures, and studies examining communication with children were excluded(see eAppendix 2 and eAppendix 3 in the Supplement). In addition, studies that developed orevaluated communication interventions were excluded because these studies prescribedcommunication strategies instead of evaluating established communication practices. The searchwas limited to studies published in English, which generally gives a sufficient assessment of a giventopic,9,10 and to studies published after 1980. Three reviewers (M.J.T., S.H., and M.C.S.) performedtitle screening, and 1 reviewer (M.J.T.) retrieved the full text of relevant titles, selected studies, andextracted data.
Methodological Quality ReviewOne reviewer (M.J.T) assessed the quality of all studies using the previously validated CriticalAppraisal Skills Program (CASP) tool for Qualitative Studies.11 A second reviewer (N.K.J.A.) verifiedthese assessments.

Statistical AnalysisIndividual study results and quality reviews are presented, and overall results are synthesizeddescriptively. Variables and outcomes extracted from individual studies were too diverse forquantitative synthesis. Continuous data are expressed as means with SDs or as medians withinterquartile ranges (IQR). No statistical testing was conducted.
Results
Search and Study SelectionThe Figure shows an overview of study selection. Thirty full-text articles from the search werereviewed, of which 20 studies were excluded (see eAppendix 4 in the Supplement). Seventeen ofthese studies were excluded because they did not include any data about anesthesiologist-patientcommunication during routine encounters. Three studies were excluded because they were aboutcommunication during procedures. The remaining 10 studies were included, and the Web of Sciencesearch returned 2 more studies, resulting in 12 studies for review.12-23
Study CharacteristicsStudy characteristics are summarized in Table 1. All studies included descriptive statistics, and 5studies13-15,20,23 performed some statistical modeling. Ten studies collected raw communication dataon clinical encounters by audiotaping,15,17-20,22,23 videotaping,16 or direct observation with anexperienced observer.12,13 One study collected data using questionnaires only,14 and another used

JAMA Network Open. 2020;3(11):e2023503. doi:10.1001/jamanetworkopen.2020.23503 (Reprinted) November 12, 2020 4/15

semistructured interviews.21 Of the studies that performed qualitative analyses, only 1 study15
specified a qualitative analysis approach and framework24 for data coding.
Methodological QualityThe summary of the methodological quality is shown in Table 2. Only 4 studies14,16,18,20 usedpreviously validated tools to collect or code data, and 1 study21 created and validated a survey. Eightstudies12,15-20,22 used 2 or more assessors to code recorded data. Eleven studies12,13,15-23 wereevaluated on all CASP criteria, with a median (IQR) score of 4 of 5 (3-5). One study14 was onlyevaluated on 4 of the CASP criteria and scored 3 of 4. Methodological issues and assessment ofquantitative analyses for studies that conducted statistical modeling are shown in Table 3.
Description of Content of CommunicationOnly 2 studies reported communication regarding adverse postoperative medical events, and thiscommunication behavior was reported in only 46 of 1284 consultations (3.6%) across all studies. Ana priori decision was made to specifically evaluate papers for communication data in the followingcategories: (1) discussion of therapeutic options including informed consent, patient comprehension,and risks/benefits, (2) elicitation of values and preferences, (3) shared decision-making, and (4)communication about postoperative care. These categories were chosen because they highlightcommunication that is central to patient-physician consultations around major interventions.Because of the broad types of data found in the review, the second and third categories werecollapsed into a single category, and other data was added as a category to capture data that did notfit into previously defined categories. Study results are summarized in Table 4.
Informed Consent and Patient ComprehensionTen studies12,13,15-17,19-23 included data on these topics. Two studies16,23 examined communication ingeneral without a specific focus. One study of patient and anesthesiologist utterances duringconsultations16 identified a mean of 23% of utterances as being related to patient counseling (exactproportion not provided); however, the coding method used suggests that most utterances coded ascounseling were likely related to technical and logistical aspects of care. A similar result was seen ina study of anesthesia consultations with standardized patients,23 which used mock patient scenarios

JAMA Network Open | Anesthesiology Anesthesiologist to Patient Communication: A Systematic Review
JAMA Network Open. 2020;3(11):e2023503. doi:10.1001/jamanetworkopen.2020.23503 (Reprinted) November 12, 2020 5/15

and 2 different standardized patients. In this study, only a mean of less than 1 minute was spentmaking a plan in each encounter.23
Seven studies13,15-17,20,22,23 contained data about risk and benefit discussions; 3 studies13,17,22
specifically evaluated communication of risks. One study17 found that during 91 clinical encounterswith parents of children undergoing anesthesia, in 27 consultations (29.6%) no risks were discussed,and in a further 23 consultations (25.3%), only a general statement of risk was included. Serious riskswere only discussed in 4 encounters (4.4%). In adults undergoing elective surgery, another study13
found that during 40 routine encounters, only 31 preoperative consultations (77.5%) includeddiscussion of at least 1 risk. Where risk was part of consultations (n = 151), patients were almostalways satisfied and not distressed by the discussion (146 of 151 consultations [96.7%]). Conversely,in consultations where no risks were discussed (n = 115), most patients (96 [83.5%]) believed thatthere was no risk to anesthesia at all.13 A small study on epidural insertion22 found a similar degree ofvariability, where the number of risks discussed in consent conversations varied from 0 to 11 perencounter. In studies with a focus other than risk communication that had ancillary data about riskdiscussions, there was a similar degree of variability.15,16,20,23 Most risks specifically evaluated inthese studies were minor, short-term risks. Global assessment of informed consent was evaluated inonly 1 study,15 which found that in conversations with parents of children undergoing anesthesia, theminimum requirements for informed consent were included in 68 of 97 cases (70.1%). Only aminority of conversations (12%, exact proportion not provided) included all 7 aspects of fullyinformed consent as defined by the authors.
Data related to patient comprehension of information communicated by anesthesiologists wereextracted from 4 studies.12,15,19,21 Among studies with objective measures of patient comprehension,patient understanding of risks and benefits of various anesthetic options was poor. For example, 1study showed that many parents recalled a description of the anesthesia planned for their child(96.2%, exact proportion not provided) and plans for postoperative pain control (81.2%, exactproportion not provided), but follow-up questions suggested very few parents fully understood risks,benefits, and complications (28 of 263 parents [10.6%]).21 In another study, parents frequentlyreported understanding risks, benefits, and the anesthetic plan (88%, 96%, and 96%, respectively;exact proportions not provided).15 However, this study only included self-reported parental
Table 3. Methodological Issues Identified in Included Papers
Source Potential for biasBabitu and Cyna,12 2000 Hawthorne effects: patients primed to think about technical terms by enrollment; presence of observer biases anesthesiologist. May exclude terms
not on standardized list used in the study. Small sample and limited patient population.Barneschi et al,13 2002 Small sample. Tools not validated; data only assessed and coded by 1 person. High chance of Hawthorne effect with a direct observer. Data about
risks discussed was limited to predetermined list of potential risks. Large proportion of patients had previous anesthesia, which may have reducedthe chance the anesthesiologist would discuss risks. Quantitative analysis: no primary outcome, no adjustment for multiple comparisons, noinformation on logistical model variable selection or assessment of modeling assumptions. Full final model not presented in the article.
Flierler et al,14 2013 Not designed around a primary objective. Quantitative analysis: no primary outcome, poor justification for sample size.
Gentry et al,15 2017 Small sample of consecutively enrolled patients. Measures of parental recall and understanding of information in the pediatric preanestheticencounter were based solely on the perspective/opinion of the parent, with no objective assessment. Tools for variable assessment not validated.Quantitative analysis: 2 primary outcomes, no sample size calculation, not clear how clustering by clinician was included into model.
Kindler et al,16 2005 No major sources of bias identified beyond selection bias; Hawthorne effect minimized well.
Lagana et al,17 2012 Substantial potential for Hawthorne effect given the direct proximity of observer and the nature of the research question. Did not use validatedtool for data collection.
Nuebling et al,18 2004 Large potential for Hawthorne effect.
Sandberg et al,19 2008 Likely underreported unexplained medical terms used in consultations, given that this is defined by patient queries and these are likely to be asubset of the medical terms misunderstood by patients.
Stubenrouch et al,20 2017 Large potential selection bias. Quantitative analysis: arbitrary exclusion of physicians with low representation in data set, variable selection inmultivariable model not explained or justified, no assessment of modeling assumptions.
Tait et al,21 2011 Entire data set is from parental recall, thus, high risk of recall bias. Selection bias of parents willing to participate, although enrollment was 89%successful.
Trumble et al,22 2015 Large potential for Hawthorne effect. Selection bias of patient and anesthesiologists willing to participate. Small sample size.
Zollo et al,23 2009 Substantial potential for Hawthorne effect given that the participants knew the interviews were conducted with standardized patients.Standardized patient roles may represent outliers from general population. Quantitative analysis: unclear which specific variables were thedependent variables in multivariable modeling (ie, no clear hypothesis or association under evaluation), no justification of covariates included inmodels, no assessment of modeling assumptions or multicollinearity.

JAMA Network Open | Anesthesiology Anesthesiologist to Patient Communication: A Systematic Review

comprehension. When considering specific words used in consultations, 1 study12 demonstrated thatalthough patients misunderstood a minority of technical terms used by anesthesiologists (49 of 484terms [10.1%] misunderstood across all encounters), there was at least 1 instance of patientsmisunderstanding in 32 of 68 individual encounters (47.1%).12 Another aspect of communicationrelating to patient comprehension was evaluated by a study that measured the amount ofinformation given to patients preoperatively by anesthesia professionals.19 This study found thatpatients’ information storing capacity was consistently exceeded in preoperative encounters.19
Shared Decision-MakingFive studies14-16,20,23 had data about eliciting patient preferences and shared decision-making. In the2 studies16,23 that evaluated communication generally, elicitation of patient preferences and valueswas uncommon. In 1 study,23 anesthesiologists spent less than 1 minute obtaining patientperspectives during encounters that were a mean (SD) of 15.9 (4.9) minutes long. Another study16
showed no utterances eliciting patient preferences during consultations. Across 21 encounters in thisstudy that required a shared decision, the Observing Patient Involvement Scores (OPTION scores25)were poor, with elicitation of patient input categories receiving the lowest scores.16 There weresimilar findings in a study of informed consent in pediatric anesthesia,15 which showed that elicitationof parental preferences was uncommon (18% of consultations, exact proportion not provided). Twostudies14,20 examined shared decision-making. In 1 study of shared decision about neuraxial vsgeneral anesthesia,20 OPTION scores showed that anesthesia professionals rarely explained thebenefits and risks of anesthetic options and did not elicit or make adequate attempts to integratepatient preferences into decision-making. Another study14 had similar findings: most patients(>90%) wanted to be involved in decisions about their care, and anesthetists tended tounderestimate patients’ desire for shared decision-making.
Discussions About Postoperative CareDiscussions about postoperative care were rare: this type of communication was described in 5studies,13,16,17,21,23 and postoperative pain control dominated these discussions. Only 2 studies13,17
presented data on communication about specific adverse outcomes. In these studies, there were 4instances of communication about postoperative events across 91 interviews (4.4%) in 1 study,17 anddeath or severe permanent harm discussed in 20 of 272 interviews (7.4%) and 22 interviews (8.1%),respectively, in another study.13 None of the studies had any data about elicitation of patientpreferences regarding direction of care in the case of serious adverse events.
Other DataEight studies13-16,18,20,21,23 had some additional data about patient satisfaction or perception of thequality of the encounter following anesthesia consultations. Satisfaction was generally high,regardless of which specific components were included in interviews,15,20 and satisfaction may havea positive association with degree of patient involvement in care decisions14 and with moreexperienced anesthesia professionals.23
Discussion
This systematic review of the literature on communication between anesthesia professionals andpatients found only 12 studies that met inclusion criteria. The studies had an overall moderate levelof methodological quality. The main finding is that communication about postoperative care wasrarely described in preoperative consultations with anesthesia professionals; the literature had nodata describing anesthesiologist-patient communication addressing protracted ICU stay, protractedventilation, and end-of-life care in the setting of postoperative incomplete recovery. These findingsare consistent with a previous narrative review on patient-anesthesiologist communication7;however, this review contributes a more robust summary of the evidence by using a systematic

search strategy, extracting and qualitatively collating data from superior data sources, assessing thequality of each study using an established evaluation tool, and including 11 studies that, to ourknowledge, have not been summarized in any previous review on this topic. These data are alsosimilar to previously published data on surgeon communication, showing little elicitation of values orpreferences regarding these issues in surgical consultations.1,2 Therefore, most patients whoundergo major surgical interventions do not have preoperative discussions about values,preferences, or goals of care that address the scenario of protracted or incomplete recovery fromsurgery. Several other findings emerge from the data. First, informed consent, including discussionof risks and benefits, is highly variable, and patient comprehension of risks, benefits, and therapeuticalternatives is frequently poor when measured objectively. Second, anesthesia professionalsfrequently give patients unmanageable amounts of information, and communication is often focusedon technical and logistical aspects of care. Lastly, anesthesiologists infrequently engage in elicitationof patient values and shared decision-making, despite patients’ apparent desire to be involved indecision-making.
Professional society guidelines in anesthesia recommend that “anesthesiologists should includepatients, including minors, in medical decision making that is appropriate to their developmentalcapacity and the medical issues involved.”26 However, there are many barriers to discussions ofpatient values, preferences, and goals of care in the preoperative setting. In many North Americansurgical centers, anesthesiologists only become involved in the care of surgical patients after theyhave made the decision to proceed to the operating room with their surgeon. Therefore, it is likelythat many anesthesiologists focus on getting the patient through the operation and may see this kindof communication and patient value exploration as not a part of their job. Second, there are largefinancial incentives to proceed to the operating room, for surgeons as well as anesthesiologists,putting additional emphasis on moving the patient through the operating room. Third, manyanesthesiologists lack the specific expertise to speak to perioperative issues that reach beyond theoperating room. Lastly, given the volume of patients seen at anesthetic clinics, anesthesiologistslikely feel tremendous time pressure and probably feel they do not have adequate time for (and arenot adequately compensated for) protracted discussion of perioperative values, preferences, andgoals of care. In cases where there are nontrivial risks that may result in a significant change in apatient’s health status or prolonged burdensome care (for example, ventilator dependence after apostoperative stroke), then anesthesia consultations without discussion of postoperative care andelicitation of patient preferences may represent a missed opportunity to raise these issues.Identifying patients at risk for postoperative complications, such as prolonged mechanicalventilation, weakness, and postoperative delirium, can provide an important perspective onperioperative decisions. Literature on communication from outside anesthesiology suggests thatpatients often agree to a plan of care that is inconsistent with their values and preferences, includingundergoing surgery.27 Informed consent for major surgery that explores these factors is oftenpossible in a 20- to 30-minute clinical encounter.28 Therefore, it seems both feasible and valuable foranesthesiologists to engage in balancing risks and benefits in the context of the patient’s valuesduring preoperative consultations, especially when anesthesiologists are involved inpostoperative care.
The 2 other physician specialties that routinely encounter surgical patients, namely surgery andcritical care, have studied communication extensively compared with the findings here. For example,there have been several recent reviews on surgeon-patient communication,1,29,30 including asystematic review1 that only included studies with audiotaped or videotaped interactions and at least1 objective measure of surgeon behavior or communication skills. This review reported data from 21studies and an additional 13 companion reports. If these selection criteria were applied to thissystematic review of anesthesia and patient communication, only 1 study would be included.Similarly, there have been multiple reviews of physician-patient communication in critical caremedicine,31-33 a discipline in which specific types of communication, such as end-of-life

communication34,35 and communication strategies for difficult decision-making,36-38 have beenbroadly evaluated.
Based on the data in this review, several hypotheses follow regarding strategies to improvepatient-anesthesiologist communication. First, if anesthesia professionals adapt to patients’individual communication needs, patient participation and satisfaction may improve, although thisstrategy has not led to measurable improvement in communication about end-of-life issues in ICU.39
Second, while there is tension between providing too much information (risking informationoverload) and not providing enough information (risking inadequate patient understanding andinformed consent), the data suggest that communication may improve if anesthesia professionalsidentify and emphasize important nontechnical information specific to each individual patient.Lastly, for anesthesiologists involved in perioperative medicine, patients who are at high risk ofincomplete recovery may benefit from elicitation of values and preferences regarding postoperativecare during preoperative consultations. Shifting the focus of anesthetic care to perioperativemedicine and specifically improving preoperative communication about goals of care is likely to be asignificant challenge for the specialty of anesthesiology. Several interventions aimed at perioperativeadvance care planning have been developed and evaluated,40-42 providing some guidance foranesthesiologists expanding their practice into perioperative medicine.
LimitationsThis systematic review has several limitations. First, the search was limited to studies published inEnglish from 1980 to April 2020. Although additional data may have been published earlier orindexed elsewhere, they are not likely to be relevant to current practice. The search only found 12studies with different designs, settings, and outcomes, making synthesis challenging. Commonlimitations for the studies that were reviewed included unavoidable selection bias due to selectiveparticipation; the Hawthorne effect in studies that employed direct observation (2 of 12 studies), andthe infrequent use of validated analysis or coding tools (only 4 of 12 studies used validated tools).The survey-based studies (3 of 12 studies) were limited by recall bias of patients and health careprofessionals. Nine studies implemented mitigation strategies for these biases. Lastly, only 3 studiesprovided data about the risk category of the patients in their analyses, and most patients wereconsidered low risk for complications. Preoperative communication with patients with higher riskmay be substantially different compared with the communication patterns found in this review.These limitations make it difficult to draw concrete conclusions about communication in anesthesiaand implications for patients who have incomplete recovery.
Conclusions
This systematic review of the literature on patient-anesthesiologist communication found thatcommunication in anesthesia rarely includes discussion of postoperative care or patient values andpreferences, but rather is dominated by anesthetic planning and perioperative logistics. Thesefindings, coupled with similar data from surgical literature, suggest that most patients who arrive inthe critical care unit following a major operation have not had a preoperative discussion about values,preferences, and goals of care specific to protracted recovery or prolonged intensive care.
