Objectives This study reviews the current state of the published peer-reviewed literature related to physician burnout and two quality of care dimensions. The purpose of this systematic literature review is to address the question, ‘How does physician burnout affect the quality of healthcare related to the dimensions of acceptability and safety?’

Design Using a multiphase screening process, this systematic literature review is based on publically available peer-reviewed studies published between 2002 and 2017. Six electronic databases were searched: (1) MEDLINE Current, (2) MEDLINE In-process, (3) MEDLINE Epub Ahead of Print, (4) PsycINFO, (5) Embase and (6) Web of Science.

Setting Physicians practicing in civilian settings.

Participants Practicing physicians who have completed training.

Primary and secondary outcome measures Quality of healthcare related to acceptability (ie, patient satisfaction, physician communication and physician attitudes) and safety (ie, minimising risks or harm to patients).

Results 4114 unique citations were identified. Of these, 12 articles were included in the review. Two studies were rated as having high risk of bias and 10 as having moderate risk. Four studies were conducted in North America, four in Europe, one in the Middle East and three in East Asia. Results of this systematic literature review suggest there is moderate evidence that burnout is associated with safety-related quality of care. Because of the variability in the way patient acceptability-related quality of care was measured and the inconsistency in study findings, the evidence supporting the relationship between burnout and patient acceptability-related quality of care is less strong.

Conclusions The focus on direct care-related quality highlights additional ways that physician burnout affects the healthcare system. These studies can help to inform decisions about how to improve patient care by addressing physician burnout. Continued work looking at the relationship between dimensions of acceptability-related quality of care measures and burnout is needed to advance the field.

Strengths and limitations of this study

  • Few studies have examined the current state of knowledge about the relationship between physician burnout and the patient safety and acceptability dimensions of quality of care.

  • This systematic literature review employed a broad search of six electronic databases: (1) MEDLINE Current, (2) MEDLINE In-process, (3) MEDLINE Epub Ahead of Print, (4) PsycINFO, (5) Embase and (6) Web of Science. A manual search was also conducted. In total, 4114 unique citations were identified and reviewed by three reviewers in pairs.

  • We used a comprehensive search strategy that follows the recommended best practices of incorporating adjacency commands and synonyms for keywords.

  • One of the limitations of the search strategy employed in this systematic review is its focus on English-language publications.

  • Another potential limitation of the search strategy is the focus on published peer-reviewed articles. In doing so, our results may be subject to publication bias.

Reports from around the world indicate that about one-third to one-half of physicians experience at least one dimension of burnout.1–5 Burnout has been conceptualised as a syndrome consisting of three dimensions: emotional exhaustion (EE), depersonalisation (DP) and low personal accomplishment (PA).6 Maslach et al 7 define EE as referring to ‘feelings of being overextended and depleted of one’s emotional and physical resources’. DP is also referred to as cynicism and defined as ‘a negative, callous, or excessively detached response to various aspects’.7 PA is also referred to as professional efficacy and ‘it refers to feelings of incompetence and a lack of achievement and productivity at work’.7 Burnout has been observed to affect personal well-being through low job satisfaction8–10 and decreased mental health.11

Because physicians play an integral role in the healthcare system, the effects of physician burnout are not limited to the physicians experiencing it. Rather, physician burnout potentially impacts the entire healthcare system. For example, a recent systematic literature review reported a negative relationship between burnout and productivity (ie, early retirement, work cutback and quitting).12 The impact of productivity loss related to burnout could lead to fewer available healthcare resources that, in turn, can result in healthcare service waitlists. One estimate of the costs of physician work cutback and early retirement related to burnout suggests it totals to at least $C213 million in patient services losses.8

This raises another question about physicians who continue to practice despite experiencing burnout. Does burnout affect their practice? There is evidence that physician burnout is also related to decreased quality of patient care.5 The WHO13 and the Institute of Medicine (IOM)14 suggest that there are six dimensions for quality of healthcare: effectiveness, efficiency, accessibility, equitability, acceptability and safety.

The purpose of this systematic literature review is to address the question, ‘How does physician burnout affect the quality of healthcare related to the dimensions of acceptability and safety?’ In this review, we focus on two dimensions of quality: acceptability (ie, patient satisfaction, perceived quality of care and communication) and safety (ie, minimising risks or harm to patients). We chose these two dimensions because they reflect the quality of patient–physician interactions.15 That is, if a clinician’s well-being is compromised, their patient interactions may also be negatively affected.16 In contrast, effectiveness, efficiency, accessibility and equitability reflect the systems (ie, infrastructure, information technology and payment policies) in which practice is conducted.14


There has been growing interest in the relationship between healthcare professional well-being and quality of patient care. Although the WHO13 and IOM14 identify six dimensions of quality of healthcare, attention has focused on the dimension of patient safety. Recently, there have been four published reviews that focus on the relationship between healthcare professional well-being and patient safety.17–20 For example, Hall et al 18 consider healthcare staff well-being and Salyers et al 20 examine staff burnout as opposed to specifically examining physician burnout as our review does. de Jong et al 17 examine common mental disorders as opposed to burnout. Williams and Skinner19 look at physician satisfaction rather than burnout. Each of these published reviews answers questions that are different from the one addressed in our review. Because they seek to answer different questions, they employ search strategies and inclusion/exclusion criteria that are different from those used in our review. Consequently, they include different articles. For example, Hall et al’s18 review does not include nine articles that are in included in our systematic review. Among these, there are six articles related to acceptability and three articles related to patient safety that were not included in Hall et al’s18 review. In comparison to de Jong et al’s review,17 our review has six articles on acceptability and five on patient safety that are unique to our systematic review. None of the articles included in our review were included in Williams and Skinner’s review.19Compared with the papers included in Salyers et al’s20 review, there are four papers related to physician burnout and safety that are unique to our review and two focused on acceptability that are unique to our review. Thus, our review includes papers that have not been considered together to look at quality of care related to physician interactions with patients and the impact of burnout on physicians.

In addition, none of the published reviews considers the quality of care dimension of acceptability for physicians who have completed training. Yet, along with patient safety, this dimension reflects the quality of interactions between providers and patients. The physician–patient interactions are one of the fundamental interactions in healthcare.15 19 Furthermore, the IOM14 asserts that the rise in chronic illnesses necessitates quality interactions to enhance the collaboration between the physician and patient. Quality of physician–patient interactions is reflected in communication, perceived quality of care and patient satisfaction.14 15 It is the physician–patient interaction that supports the collaboration that will lead to better patient outcomes.15

Wallace et al 16 assert that physician well-being could be used as a quality indicator. The argument could be strengthened by also understanding how well-being is associated with the physician–patient interaction-related quality dimensions of safety and acceptability. In particular, burnout could be a focus because it reflects well-being and there are standardised measures to identify it. Furthermore, it is a facet of well-being that can be influenced by organisational factors and is under the influence of the healthcare system.16 21 22 Thus, this systematic review of the literature extends our knowledge about the dimensions of quality of care that reflect physician interactions with patients and a dimension of well-being that is affected by the work environment.


A systematic review of the literature was reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (online supplementary file 1: PRISMA checklist).23 Ethics board review was not sought because this review relied solely on publicly available sources of information.

PRISMA Checklist

Information sources

Six databases were searched: (1) MEDLINE Current (index of biomedical research and clinical sciences journal articles); (2) MEDLINE In-Process (index of biomedical research and clinical sciences journal articles awaiting to be indexed into MEDLINE Current); (3) MEDLINE Epub Ahead of Print (index of articles that appear on publisher websites in advance of the journal release); (4) PsycINFO (an index of journal articles, books, chapters and dissertations in psychology, social sciences, behavioural sciences and health sciences); (5) Embase (index of biomedical research and abstracts from biomedical, drug and medical device conferences); and (6) Web of Science (index of journal articles, editorially selected books and conference proceedings in life sciences and biomedical research).

Search strategy

Collaborating with the professional health science librarian (SB) member of this research team, search strategies were developed and tailored for each database following the Peer Review of Electronic Search Strategies guidelines24 (online supplementary file 2: search terms used in search strategy). Because recommended guidelines were used for this review’s search strategies, the search strategy that we used is also a contribution to the literature. As this literature grows, the strategy can be used in future searches on the topic. The searches were conducted in February 2017. The OVID platform was used to search MEDLINE Current, MEDLINE In-Process, MEDLINE Epub Ahead of Print, PsycINFO and Embase. Web of Science was searched using the Thomson Reuters search interface. The search period covered January 2002–February 2017; all searches were limited to English-language journals. The time frame was chosen to represent the current healthcare environments in which physicians are practicing. For example, the year 2002 was the year after the IOM’s report14 on the quality of healthcare that discussed the six dimensions of quality of care. By beginning in 2002, we have allowed for a 1-year lag after publication of this report during which healthcare settings and researchers could have incorporated the IOM’s quality of healthcare framework into their work.

Search terms used in search strategy

Our searches sought to identify articles about practicing physicians regardless of specialty working in civilian settings (ie, non-military settings). In this review, the physician search included: allergists, anaesthesiologists, cardiologists, clinical pharmacologists, clinical toxicologists, dermatologists, doctors, endocrinologists, gastroenterologists, gynaecologists, haematologists, immunologists, medical biochemists, medical geneticists, medical microbiologists, nephrologists, neurologists, neuropathologists, neuroradiologists, occupational physicians, oncologists, ophthalmologists, pathologists, paediatricians, physicians, psychiatrists, radiologists, rheumatologists, surgeons and urologists. The search strategy did not seek to exclude residents and medical students. Rather, a broad search strategy was employed to increase the likelihood that all studies on physician burnout would be found. The reference lists of all accepted full-text articles were hand searched.

Screening process

Relevant articles were identified using a multiphase screening process that involved reviewer pairs using the inclusion and exclusion criteria for this review. In the first step, titles were screened. Next, abstracts of the articles that remained after the first step were screened. The final step of the process involved screening the full text of all articles that passed the first and second phases. In the full-text screening, papers for which there was insufficient information in the title and abstract to determine relevancy were also included. Two pairs of reviewers (CSD and LT, CSD and DL) independently completed the multiphase screening process. The inter-rater reliability corrected for chance25 between CSD and LT, and CSD and DL was κ=0.96 and κ=0.98, respectively. Before moving onto each stage, disagreements were discussed until consensus was reached.

For this review, burnout was defined as a syndrome of EE, cynicism (DP) and reduced feelings of PA related to work.6 Quality of care related to acceptability was identified with measures reflecting physician–patient interactions such as patient satisfaction, perceived quality of care, physician communication with patients and physician attitudes towards patients. In addition, safety was identified by measures that reflected risks or harm to patients such as medical errors.

Study inclusion criteria were:

  1. Studies reported quality of care outcomes related to acceptability and/or safety.

  2. The sample population was comprised of practicing physicians regardless of specialty who worked in civilian settings. That is, the results were reported such that the practicing physician (as opposed to resident) outcomes were reported separately.

  3. Burnout was assessed based on a psychometrically validated measure.

  4. Paper reports original research.

Exclusion criteria were:

  1. The study sample was comprised only of residents and medical students.

  2. The study did not examine the relationship between burnout and one of the two quality of care dimensions.

  3. Burnout was not assessed based on a validated measure.

  4. The paper was a review article or commentary.

Risk of bias assessment

All included articles were assessed for risk of bias by both pairs of reviewers (CSD and LT, and CSD and DL). Disagreements between the pairs of reviewers were discussed until consensus was reached.

To assess the risk of bias in observational studies, Sanderson et al 26 recommend the use of a transparent checklist that concentrates on the ‘few, principal, and potential sources of bias in a study’s findings’. They assert that the fundamental domains should include: (1) the appropriate selection of participants, (2) appropriate measurement of variables and (3) appropriate control of confounding. In accordance with their recommendations and the Strengthening of Observational Studies in Epidemiology criteria,27 a nine-item risk of bias checklist with the following criteria adapted from Lagerveld et al 28 was used:

  1. Study population is well described to facilitate understanding about the generalisability of the results based on the study sample (eg, age, sex, location of the study, physician specialty and practice location).

  2. Data collection methods that address the risk of bias are described.

  3. Participation/response rate was at least 50% on average.

  4. The psychometric properties of the quality of care outcome measure have been tested.

  5. Statistical method was appropriate for the question being answered.

  6. Statistical significance of associations were tested and reported.

  7. Study controlled for at least one confounder such as sex or age in the analyses.

  8. Physician matched with patient.

  9. Longitudinal data was used.

Each item was scored ‘1’ if the criterion had been met. Each article could achieve a maximum score of 9. Based on their total score, articles were categorised either as low (8–9 points), moderate (5–7 points) or high risk of bias (1–4 points).


Article inclusion and exclusion results

The electronic literature search resulted in the identification of 4114 unique citations (figure 1). Based on the title review, 4020 citations were excluded; this left 94 articles for abstract review. During the abstract review, another 28 citations were excluded; this left 66 articles for full-text review. Reasons for article exclusions at full-text review were: (1) not a relevant outcome (n=10), (2) sample not comprised of physicians/cannot distinguish physicians as a group from other clinicians (n=15), (3) it was not original research (n=20), (4) burnout not measured with a validated instrument (n=1) and (5) not published in a peer-reviewed journal (n=8). After the full-text review, 12 articles remained, and their reference lists were hand searched for relevant studies. The hand search identified six additional citations; all six were excluded at full-text review.

Risk of bias assessment results

Our assessment indicated 10 of the 12 studies were of moderate risk of bias; two were of high risk of bias. Figure 2 illustrates the limitations of these studies. Two studies comprehensively5 29 described the study population from which the study sample was drawn. Two studies used longitudinal data.29 30 Other limitations involved not reporting the response rate31–34 and not controlling for possible confounding factors in the statistical analyses.34 35 There was also variability in the use of validated outcome measures; only three studies used validated instruments to measure their outcomes.31 33 35 All included studies employed appropriate statistical tests. All but one29 reported the results of the statistical testing (online supplementary file 3: risk of bias assessment checklist).

Description of the study populations

Six of the studies focused on hospital-based physicians.5 30 34–37 Among these studies, two focused on cancer34 and children’s36 specialty hospitals. In addition, one of these studies recruited surgeons practicing either in general surgery or gynaecological wards.5 One of these studies37 also included people practicing as physicians who did not have graduate educations.

The remaining five studies recruited physicians practicing in a variety of settings. Three studies sought physicians in primary healthcare centres29 31 33; they included physicians practicing in internal medicine, general practice and family practice. One of the studies29 that recruited primary care physicians focused on the quality of care only for patients with diabetes and/or hypertension.

Two studies did not specify the setting.32 38 However, of these two, one focused on surgeons.38 Finally, one study used four health plans to recruit and contained a mixture of community and hospital physicians,39 which included physicians specialising in ophthalmology, dermatology, otolaryngology, community-based gynaecology, general surgery and hospital-based cardiology.

Measuring burnout

In 9 of the 12 studies, burnout was measured using either the 22-item Maslach Burnout Inventory (MBI),6 translated version of the MBI-GS,37 translated version of the MBI-HSS30 31 or selected MBI subscales.30–38 The complete 22-item MBI measures three dimensions of burnout: EE, DP and PA. It is one of the most widely used measures of burnout in the scientific literature.40 41 One study29 used a single-item measure for burnout that correlates with the EE subscale of the MBI.42

The two remaining studies used the Copenhagen Burnout Inventory (CBI)40 and the Shirom-Melamed Burnout Measure (SMBM).41 43 The CBI is a 19-item scale comprised of three subscales that assess personal burnout, work-related burnout and client-related burnout.40 It has been shown to be correlated with mental and general health as well as job satisfaction.40 The SMBM is a 22-item measure with three subscales that assess physical fatigue, EE and cognitive weariness.41 The psychometric properties of these scales continue to be explored.41 44 45

Measuring quality of care related to acceptability and patient safety

Four types of quality of care measures related to acceptability and safety were used in these studies. In terms of patient safety, medical errors were measured. Acceptability-related measures included patient satisfaction, perceived general quality of care and physician communication/attitudes.

Patient safety measures: medical errors

Patient safety was examined with medical errors. This outcome was assessed in five studies.5 29 30 37 38 Wen et al 37 asked respondents whether they had made any medical errors including one that resulted in a patient being harmed, a medication error, delay in treatment or incomplete or incorrect item being added to the patient record. Hayashino et al 30 and Shanafelt et al 38 used similar questions about whether the respondent made major medical errors. However, the studies differed in the time frame that the respondent was asked to consider. Hayashino et al 30 asked about the past year, while Shanafelt et al 38 inquired about the past 3 months. In contrast to these studies, Klein et al 5 asked about frequency of diagnostic mistakes and treatment without specifying a time frame. The studies differ in the types of errors that they asked about (ie, major errors rather than any errors). In addition, they depend on recall and self-report. Shanafelt et al 38 note that studies have used this type of question to gather information about medical errors. However, there are also studies that have found that physicians under-report medical errors.46 Furthermore, there is evidence that physicians have a limited ability to self-assess their practice patterns.47

In addition to questions about frequency of diagnostic mistakes and treatment, Klein et al 5 included a questionnaire based on the Canadian Physician Achievement Review to evaluate physician self-perceived quality of psychosocial care, diagnosis/therapy and quality assurance.48 However, the authors note that additional work regarding its validity is warranted.5

There was only one study that did not rely on self-report to gather information about medical errors. Rabatin et al 29 used a chart audit to assess medical errors characterised by adherence to guidelines, responsiveness to ‘recurrent abnormalities’ and missed drug interactions.

Acceptability measures: patient satisfaction/perceived quality of care

With regard to acceptability measures, patient satisfaction was assessed in four studies.31 32 35 39 In two of these studies, the SERVQUAL was used to measure patient satisfaction/quality of care.32 39 The SERVQUAL was developed to measure service quality along five dimensions: (1) tangibles (ie, physical facilities), (2) reliability (ie, performs dependably and accurately), (3) responsiveness (ie, willingness to help), (4) assurance (ie, ability to inspire trust) and (5) empathy (ie, caring).49 Halbesleben and Rathert32 used a healthcare-specific version of the SERVQUAL. The psychometric properties of the scale were examined.50 However, Asubonteng et al 51 have raised questions about the strength of the scale’s psychometric properties.

Shirom and colleagues39 adapted the SERVQUAL by eliminating seven items and revising the language for physicians to rate their own quality of care using the remaining 15 items. The validity of this modified measure was not examined.

Weigl et al 36 looked at physician-perceived quality of care by asking physicians to rate two statements on a five-point scale: ‘My workload frequently leads to reduced quality of work’ and ‘Adverse work conditions frequently lead to a loss of quality.’ The authors reference the German version of the MBI as the source for these questions. However, they do not provide information about the psychometric properties of the individual use of these items.

One study31 used the Consultation Satisfaction Questionnaire (CSQ) scale that was created and validated to assess patient satisfaction with general practitioners.52 It is comprised of 18 items and measures satisfaction along four dimensions: general satisfaction, professional care, depth of relationship, and perceived time.

Finally, in their study, Weng et al 35 used two questions to indicate patient satisfaction, ‘I am satisfied with the care provided by my doctor,’ and ‘I would recommend this doctor to my friends and family.’ The first of Weng et al’s35 questions is similar to one of the CSQ’s52 general satisfaction items, ‘I am totally satisfied with my visit to the doctor.’ However, the use of this single-item has not been validated. A version of the second question has been used to measure satisfaction and was correlated with the EUROPEP patient satisfaction questionnaire.53

Acceptability measures: communication/attitudes

Two studies focused on physician communication/attitudes.33 34 Using audiotapes of physician/patient interactions, Ratanawongsa et al 33 assessed the interactions by employing the Roter Interaction Analysis System (RIAS).54 RIAS is a validated method of categorising these interactions into three categories related either to content, affection or process.55 There is evidence that there is an association between the content and the socioemotional nature of the interactions as categorised using the RIAS and patient satisfaction.54 55

Travado et al 34 examined the association between burnout and communication using two measures: the Self-Confidence in Communications Skills and the Expected Outcomes of Communication.56 In their article, Parle and colleagues56 note that exploration of the psychometric properties of both measures were being conducted but were not yet completed. Both were developed to understand the communication skills of physicians working with cancer patients.

Study outcomes: burnout and quality of care

In this subsection, we report about the quality of care outcomes from the included studies (table 1). This review of outcomes begins by describing the findings regarding the association between burnout and patient safety (ie, medical errors). It is followed by reporting of the acceptability outcomes as measured by patient satisfaction/perceived quality of care and physician communication/attitudes.

Outcomes: burnout and medical errors

Table 1 contains the outcomes reported by the included papers. In terms of findings for the association between burnout and medical errors, there was a consistently significant relationship between burnout and medical errors among four papers focusing on this relationship.5 30 37 38 Shanafelt et al 38 reported significantly higher odds of a major medical error during the past 3 months among physicians with higher EE and DP but lower odds among physicians with higher PA. Hayashino et al 30 also observed significant associations between a major medical error during the past 12 months and higher levels of EE and DP; however, the relationship with PA was not significant. Klein et al 5 reported significant associations between high burnout and diagnostic error, therapeutic error, suboptimal psychosocial care, suboptimal diagnosis and treatment and suboptimal quality assurance. Wen et al 37 found higher odds of medical errors among physicians with either some or serious burnout symptoms as opposed to no burnout symptoms.

The one paper29 that assessed errors based on chart audits did not find a significant relationship between burnout and medical errors. However, it should be noted that this study focused on treatment for a subgroup of patients with chronic disorders that included diabetes and/or hypertension.

Outcomes: burnout and patient satisfaction/quality of care

Among the four studies that examined the relationship between burnout and patient satisfaction/quality of care, three studies observed a significant relationship between patient satisfaction/quality of care and either burnout or at least one dimension of burnout.31–33 35 The one study33 that combined the MBI EE and PA dimensions to create a single burnout score did not find a significant relationship between the score and patient satisfaction. Because it used only two subscales and one of them was PA rather than DP, it is not clear regarding the extent to which their choice of subscales was consistent with the other measures of burnout.

Among the three studies that reported separate MBI dimensions, there seemed to be a consistent observation that high DP is significantly related to lower patient satisfaction.31 32 35 However, the significance of the association between EE and patient satisfaction varied among studies; Anagnostopoulos et al 31 reported a significant correlation, but Weng et al 35 did not.

At the same time, Shirom et al 39 described a significantly negative relationship between high EE and physician perceived quality of care. Weigl and colleagues36 also found a significant negative relationship with EE but did not find a significant relationship between DP and physician perceived quality of care.

Outcomes: burnout and communication/attitudes

Travado et al 34 found a significantly positive relationship between PA and self-confidence in communication skills as well as with negative expected outcomes of communication. They also observed a significantly negative association between PA and positive expected outcomes of communication. In addition, Ratanawongsa et al 33 reported a higher probability of negative rapport with medium and high burnout.


This systematic literature review identified 12 studies of which 10 had a moderate risk of bias and two had a high risk of bias. The results of these physician burnout studies show that patient safety has been primarily measured by examining medical errors. The acceptability outcomes have been captured using two groups of indicators that measure patient satisfaction/perceived quality of care and physician communication/attitudes towards patients. The majority of these studies examined the relationship between burnout and acceptability. Among the acceptability-related quality of care outcomes, the focus has been on patient satisfaction/perceived quality of care.

The results of four of the five included studies that reported on the relationship between burnout and medical errors suggest there is evidence that burnout is associated with physician self-perceived medical errors and suboptimal care. However, there is equivocal evidence that specific dimensions of burnout are related to the acceptability dimension of quality of care as measured by patient satisfaction, perceived quality of care or physician communication/attitudes. Thus, the current body of evidence suggests there is moderate evidence for the association between burnout and safety aspects of healthcare, whereas the evidence is weaker for the patient-related acceptability aspects of quality.

Strengths and limitations of interpreting the literature

One of the important questions raised by burnout studies in general is highlighted by Klein et al’s5 and Shirom et al’s39 use of non-MBI scales. Klein and colleagues5 used the CBI, while Shirom et al 39 used the SMBM. One of the criticisms that the separate developers of these two scales raise is that the MBI does not fully assess burnout.39 40 Rather, both groups argue that fatigue and exhaustion are fundamental to the definition of burnout.39 40 However, this emphasis on exhaustion may be reflected in the fact that EE is the most widely studied of the MBI dimensions.57 This would argue for the assessment of this dimension in studies of burnout and the individual reporting of it.

Another limitation of these studies was the reliance on physician self-report data for the assessment of medical errors. The self-report could be influenced by a number of factors including recall bias and social desirability. There is a potential additional bias introduced if self-report is used for both the outcome and the problem.58 The presence of burnout could also influence perceptions. For example, Fahrenkopf et al 59 observed a discrepancy between the results of chart audits and physician self-report; those with higher burnout scores reported higher numbers of medical errors than the chart audits would suggest.

An alternative to self-report would be observational data. However, watching physicians while they practice could lead to a Hawthorne effect. Another alternative would be to review medical records to identify errors. However, this relies on the accuracy of the records. Also, it is not clear what types of medical errors should be assessed—major errors leading to an adverse event or any medical error regardless of outcome? In their study, Fahrenkopf et al 59 used a standardised method to abstract information from charts and trained reviewers to categorise the errors into groups: (1) preventable adverse event, (2) non-preventable adverse event, (3) potential adverse event and (4) error with little potential for harm. Further work could examine how physicians define errors as well as the reliability of error self-report. In addition, to improve the comparability of outcomes, future studies could incorporate and report severity of medical error scores.

There was a diverse set of measures used in the studies that focused on patient satisfaction and quality of care. They varied in which outcomes were measured and how they were measured. In addition, the majority of the studies did not use validated outcome measures. For example, perceived quality of care was assessed using a variety of measures that ranged from two items for which the psychometric properties were not tested to a scale designed to assess service quality on six dimensions. Thus, it is difficult to discern the extent to which the study results could be attributed to the differences in the dimensions assessed. Further exploration along this line of inquiry could be undertaken to understand the aspects of satisfaction and perceived quality of care that are significantly associated with burnout.

An additional limitation of the existing body of literature is the reliance on cross-sectional study designs. Cross-sectional design limits conclusions regarding causality. Cross-sectional data do not distinguish the sequence of conditions. For example, did burnout cause decreased quality of care? Or, did decreased quality of care cause burnout? At best, the cross-sectional data used in these studies can only be used to determine that there is a relationship. At the same time, there is evidence from studies that have used longitudinal data to examine burnout and medical errors among residents that there is a causal relationship such that burnout causes errors.60 However, the longitudinal data that contribute to the strength of West et al’s study60 are potentially weakened by the self-reported medical errors.

Finally, only two studies5 29 described the population from which the study sample was drawn. Thus, it is difficult to determine whether there was a difference between the study participants and non-participants. To aid in the interpretation of the results (ie, the generalisability), it would be useful for future studies to report this type of information.

Strengths and limitations of the search strategy

Although six databases were used in the search, articles that did not appear in any of the databases would have been missed. To decrease the possibility of this occurring, we employed a broad scope in development of the search terms for each database and followed this with a hand search of included articles. Another potential limitation is the fact that the search focused on articles published in English-language journals. However, despite the English-language constraint, the identified studies originated in European, Middle Eastern, North American and Asian countries. This indicates that although the research was not conducted in countries where English is the first language, at least some of these researchers publish in English-language journals. Finally, there is also a potential limitation associated with focusing on published peer-reviewed articles. In doing so, we may be subject to publication bias.61 At the same time, the quality of the grey literature has been questioned, because it is not necessarily subject to critical assessment prior to being published.62 As a result, unpublished studies may be of lower quality and have greater risk of bias in their study designs.


The focus on quality related to direct care can highlight additional ways that physician burnout affects the healthcare system. These results contribute evidence about whether the effects of physician burnout are limited to physicians or whether consequences of physician burnout are more extensive. They also can help to inform decisions about how to improve patient care by addressing physician burnout. That is, decisions can be informed when confronting a question of how to improve quality of patient care. There are a number of ways in which this may be done through investment in capital such as new technologies. The results of this systematic review suggest that an alternative investment could be in human resources as represented by physician staff.

The results of this systematic literature review suggest that there is moderate evidence that burnout is associated with safety-related quality of care. Because of the variability in the way patient acceptability-related quality of care was measured and the inconsistency in study findings, the evidence supporting the relationship between burnout and patient acceptability-related quality of care is less strong. Future research evaluating burnout interventions for physicians could consider looking at safety-related quality of care to assess the effectiveness of these interventions. Continued work looking at the relationship between dimensions of acceptability-related quality of measures and burnout is warranted.
