Burnout Assessment Among Surgeons and Surgical Trainees During the COVID-19 Pandemic: A Systematic Review.

BACKGROUND: The objective of the current study was to summarize current research on burnout among surgical trainees and surgeons during the COVID-19 pandemic.
METHODS: PubMed, SCOPUS, Embase, and Psych INFO were systematically searched for studies that evaluated burnout during the COVID-19 pandemic among surgical trainees and surgeons.
RESULTS: A total of 29 articles met inclusion criteria, most of which originated from the United States (n = 18, 62.1%). Rates of burnout ranged from 6.0% to 86.0%. Personal factors responsible for burnout were fear of contracting/transmitting COVID-19 (8 studies, 27.6%), female gender (8, 27.6%), and younger age (5, 17.2%). Professional factors contributing to burnout included increased COVID-19 patient clinical load (6, 20.7%), limited work experience (6, 20.7%), reduction in operative cases (5, 17.2%) and redeployment to COVID-19 wards (4, 13.8%). The COVID-19 pandemic negatively impacted surgical education due to reduced number of operative cases (11, 37.9%), decreased hands-on experience (4, 13.8%), and not being able to complete case requirements (3, 10.34%). The shift of didactics to virtual formats (3, 10.3%), increased use of telemedicine (2, 6.9%), and improved camaraderie among residents (1, 3.4%) were viewed as positive consequences.
CONCLUSION: COVID-19 related burnout was reported in as many as 1 in 2 surgical trainees and attending surgeons. Intrinsic- (i.e., gender, age), family- (i.e., family/being married/having children or being single/not having children), as well as work-related extrinsic- (i.e., work-force deployment, risk of infection/spread, changes in educational format) factors were strongly associated with risk of burnout. These factors should be considered when designing interventions to ameliorate burnout among surgical trainees and surgeons.

Introduction

With over 220 million confirmed cases and 4 million deaths to date, the COVID-19 pandemic has placed a heavy burden on health care providers, trainees, and medical delivery systems worldwide. Front-line workers were expected to provide high-quality patient care despite limited resources, staffing shortages, and potential exposure to COVID-19. , Emerging evidence suggests that these working conditions had a detrimental psychological impact on health care workers, including increased rates of depression, anxiety, and insomnia. In the context of surgery, a paradigm shift led to constantly evolving clinical guidelines, including the delay of non-emergent surgical procedures. For these reasons, the impact of the COVID-19 pandemic on the well-being of surgical trainees and surgeons, and the resulting occupational “burnout” (i.e., a negative psychological reaction to chronic occupational stressors), has become a matter of great concern.

Prior to the COVID-19 pandemic, surgeons were already vulnerable to burnout due to long work hours, challenges in patient care, and difficulties with work-life balance. Factors associated with risk of burnout can be at the individual and/or institutional level and consequences of burnout can impact both individual providers (i.e., depression, substance abuse and suicide), as well as organizations (i.e., higher staff attrition, increased risk of medical errors).6, 7, 8 The COVID-19 pandemic, and unique circumstances associated with its various waves/phases, may have exacerbated these conditions, exposing surgeons to an even higher risk of burnout. While several studies have examined the impact of the COVID-19 pandemic on burnout among physicians in general, no attempt has been made to synthesize the findings of these studies to assess the impact on surgeons specifically. Therefore, the objective of the current study was to conduct a systematic review of the literature to summarize data on burnout among surgical trainees and attending surgeons during the COVID-19 pandemic.

Methods

A systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Literature searches were performed using the following databases: PubMed/Medline, SCOPUS, Embase and Psych INFO. The search strategies are provided in Supplemental Table 1 and included the following terms and variations listed in the Medical Subject Headings index: “Surgeons'' (e.g., surgical trainee or resident), “Burnout” (e.g., occupational stress) AND “COVID-19” (e.g., coronavirus).

Selection Criteria and Eligibility

Included articles were published in English between January 1, 2020, and August 30, 2021, and had empirical qualitative and quantitative research designs. Articles related to burnout among surgical trainees and practicing surgeons during the COVID-19 pandemic with burnout mentioned in the abstract, keywords, introduction, and/or methods were included. All studies assessing burnout in surgical trainees and surgeons were included, regardless of the surgical subspecialty, as well as reports that included other healthcare providers in addition to surgeons. As the COVID-19 pandemic is a global event, articles were not excluded based on location. Summaries, reviews, commentaries, and poster presentation abstracts were excluded. Studies assessing burnout exclusively in health care providers other than surgical trainees or surgeons or including only medical students were also excluded. Table 1 includes a summary of study inclusion and exclusion criteria.

Published globally.5. Published in English.	1. Related to burnout in nurses and medical students, without inclusion of surgeons in training or surgeons.2. Summaries, reviews, commentaries and poster presentation abstracts.3. Related to burnout of physicians in non-surgical specialties.

Burnout Assessment Scales

Studies were included in the systematic review regardless of which burnout assessment tool was used. The tool used most often was the Maslach Burnout Inventory (MBI). The MBI is a psychological assessment instrument including 22 items pertaining to occupational burnout that includes 3 subscales: emotional exhaustion (EE), depersonalization (DP), and personal accomplishment (PA). Other tools included the Mini-Z burnout assessment scale, the Professional Fulfilment Index (PFI), the Utrecht Burnout Scale (UBOS), the Professional Quality of Life Measure V5, the Resident Fellow Well-Being Index (RSWBI), and the Shirom-Melamed Burnout Measure (SMBM). Studies were also included that utilized investigator-created assessments (ICA) tool.

Data Extraction

All articles returned from the formal search strategy were imported into Covidence, a web-based software designed to aid in systematic review management and recommended by Cochrane. Literature screening took place in two phases. In the first phase, two authors (CFS, AP) independently screened article titles and abstracts. In the second phase, the same authors screened full-text articles for inclusion and exclusion criteria. In both phases, a third author (EPK) resolved any conflicts or discrepancies. Full text interrater reliability was Κ = 0.87.

Data was abstracted by two study team members (CFS, BM). The following data was abstracted: article title, year, journal, authors, country, abstract results, abstract conclusions, conflict of interest statement, inclusion criteria, exclusion criteria, type of study, study design, aim, recruitment procedure, impact on personal/professional life, number of providers included, number of surgical trainees/surgeons, types of providers included, surgical specialties, years in practice, age, gender, race, family composition, healthcare setting, primary and secondary outcomes, measure of burnout used, operational definition, rates of burnout, factors associated with burnout (personal or professional), risk mitigation, risk intervention, and consequences of COVID-19. Data were extracted around the variable “conflict of interest” to detect any biases in the included studies.

Results

A total of 283 titles/abstracts were imported into Covidence to be considered during the initial title and abstract screening phase. Among these reports, 88 were identified as duplicates and removed. After 195 article titles and abstracts were screened, 132 were considered irrelevant based on study inclusion and exclusion criteria. The remaining 63 articles underwent the full-text screening procedure, during which articles were excluded because they were not about surgeons (n = 15), were not empirical studies (n = 6), did not explicitly assess burnout (n = 5) or only mentioned burnout in the context of the discussion (n = 4) or because the full-text article was not available (n = 4). The remaining 29 studies comprised the final sample and underwent data extraction by two members of the team. The study search and screening procedure are illustrated in Figure 1 .

Overall Study Characteristics

Among the 29 included studies conducted between April 2020 and December 2021, most were published in 2020 (n = 16, 55.2%),18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33 whereas the remaining papers (n = 13, 44.8%) were published in 2021. , 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45 The majority of studies utilized cross-sectional, quantitative methods (n = 27),18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33 , 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45 with only a small minority being qualitative (n = 2). , The sample size varied widely across studies, ranging from 24 to 2040 for quantitative studies and from 16 to 870 for qualitative studies. Most of the studies were about the healthcare system in the United States (n = 17), , , , 26, 27, 28, 29 , 32, 33, 34, 35, 36, 37, 38, 39 , , while the remaining reports were from Singapore (n = 3), , , Egypt (n = 2), , the United Kingdom (n = 1),4 France (n = 1), Brazil (n = 1), Pakistan (n = 1), the Netherlands (n = 1), Romania (n = 1), and the Czech Republic (n = 1). Almost all studies included surgical trainees (residents, fellows) as part of the studied population (28 studies, 96.6%). However, a minority of articles also included attendings and/or consultants in the studied population (10 studies, 34.5%). , , 27, 28, 29 , , , , , Slightly more than half of surgical trainees/surgeons involved were female (n = 5486, 54.3%), while 45.6% (n = 4599) of the total sample were male. None of the articles declared any conflicts of interest related to the studies. A brief summary of all included articles and the respective results can be found in Table 2 .

Burnout Rates and Specialties

The overall rate of burnout among surgical trainees/surgeons across all studies ranged from as low as 6.0% to as high as 86.0%. , Of note, the reported rates of burnout varied considerably based on the scale used to assess them. Specifically, the 10 studies using the MBI reported rates of burnout ranging from 6.0% to 86.0%.21, 22, 23 , , , , , , , Additionally, the 2 studies that used the Mini-Z burnout assessment scale reported rates of burnout of 14.7% and 21.8%. , Two other studies assessed burnout rates through the PFI, and reported burnout rates of 15.9% and 34.0%. , Less commonly used tools to measure burnout included the UBOS (1 study, burnout = 9.0%), the Professional Quality of Life Measure V5 (1 study, burnout = 48.9%) and the RSWBI (1 study, burnout = 51.5%). However, not all studies used previously validated tools to measure rates of burnout. In 8 studies (27.6%), investigators instead opted to design and implement their own tools or investigator created assessment (ICA). Rates of burnout measured using the investigator created assessment tools varied widely, ranging from 12.7% to 68.0%. , , , , , , , Chou et al. compared the rate of self-reported burnout (24.4%) with the rate of burnout assessed via SMBM (10.9%).

Reported burnout rates varied by surgical subspecialty. Among 4 studies including only ENT trainees and attending surgeons, reported burnout rates ranged from 10.9% to 21.8% (SMBM 10.9%, ICA 12.7%, single-item Mini-Z 14.7% and 21.8%). , , , Among 4 studies including only neurosurgery trainees and attending surgeons, reported burnout rates ranged from 20.4% to 68.0% (aMBI 20.4%, aMBI 26.1%, ICA 35%, ICA 68%). , , , Among 3 studies including only orthopedic surgery trainees and attending surgeons, reported burnout rates ranged from 15.9% to 57.3% (PFI 15.9%, EE & DP from MBI 19.6%, MBI and ICA 57.3%). , , The highest reported rate of burnout was among a cohort of plastic surgery residents related specifically to their experience with virtual education: 88% of residents expressed being always, often or occasionally burned out and 79% were emotionally drained from videoconferencing.

Factors Associated with Burnout

Studies included in the current review identified both personal and professional factors associated with burnout in surgical trainees/surgeons during the COVID-19 pandemic. Personal factors contributing to burnout most often were fear of a family member potentially contracting COVID-19 (8 studies, 27.6%) , 23, 24, 25 , , , , and female gender (8 studies, 27.6%),27, 28, 29 , , , , , followed by concerns for one's own safety (6 studies, 20.7%), , , , , , and younger age or fewer years of practice (5 studies, 17.2%). , , , , Other less commonly cited personal factors associated with burnout during the pandemic are noted in Table 3 . The findings from the qualitative studies by Abdelsattar et al. and Al-Ghunaim et al. were consistent with these results, as demonstrated in their thematic analysis. For example, in the study by Al-Ghunaim et al. several comments focused on anxiety about the disease, including the “fear of bringing the virus home and infecting my family.” In turn, measures aimed at avoiding transmission of COVID-19 affected communication with family: “Not being able to live with my wife [...] makes communication harder.” As one participant from the study by Abdelsattar et al. mentioned, “[the pandemic] had a major impact on my relationships, [...] it will never go back.” ,

Several professional factors also contributed to the risk of burnout. In particular, having to care for a larger number of COVID-19-positive patients and having fewer years of clinical experience were the two most commonly reported professional factors associated with burnout (both mentioned in 6 separate studies, 20.7%). , , , , , , , , Additionally, redeployment to COVID-19 wards, an increased workload and limited availability of personal protective equipment were cited by 4 studies each (13.8%). , , , , , , , , , These and other professional factors associated with higher burnout rates are noted in Table 3. The qualitative themes highlighted by Abdelsattar et al. and Al-Ghunaim et al. echoed these results. Al-Ghunaim et al. identified a “changing and challenging work environment” as one of the most prevalent subthemes in their analysis. For example, respondents commented on the “reduced capacity for operative surgery,” the “increased workload,” and the “lack of PPE”. Similarly, participants in the study by Abdelsattar et al. complained about being “in charge of 10 to 20 intubated COVID-19 patients on a daily basis,” “[not knowing] when I would return to the OR,” “[being] pulled away from my education [that is] operating to manage these COVID-19 patients,” and “[reusing] PPE for 20 to 30 days.” ,

Impact on Surgical Education

Almost all studies involved surgical trainees (i.e., residents and fellows; 28 studies, 96.6%), and several commented on the impact of the COVID-19 pandemic on surgical education. Eleven out of 29 (38.0%) articles mentioned a marked reduction in the elective and emergent operative cases. , 18, 19, 20 , , , , , , , The decrease in surgical case volume became a matter of great concern for the residents (FIGURE 2, FIGURE 3 ).19 While surgical personnel were redeployed (4 studies, 13.8%) , , , to other areas of COVID-19 care within the hospitals, hands-on experience (4 studies, 13.8%) , , , was also felt to be compromised. Furthermore, 3 out of 29 studies (10.3%) highlighted that the residents in their program were worried about not fulfilling the minimum requirements for Accreditation Council for Graduate Medical Education (ACGME) certification. , , Of note, surgical and clinical education were rated to be of higher concern than worries about PPE shortage (p < 0.00001).

Due to implementation of public health policies, didactics were shifted to virtual platforms. Residents in 5 (17.2%) of the studies noted that the virtual format had a markedly negative impact on surgical education. , , , , In contrast, 3 studies (10.3%) suggested that the move to a virtual education format was one of the successes pertaining to the COVID-19 pandemic. , , Additional factors that were considered positive included use of telehealth (2 studies, 7.0%), , flexibility in schedules (1 study, 3.4%),34 work from home (1 study, 3.4%)4 and increased comradery among residents (1 study, 3.4%).

Discussion

The COVID-19 pandemic has created unprecedented challenges across a vast array of areas both inside and outside the field of medicine. These challenges have generated significant stress and strain on physicians and health care professionals. In fact, one survey of 20,947 physicians and other healthcare workers reported that 43% suffered from work overload and 49% had burnout. Burnout can be associated with extreme physical and emotional exhaustion. While traditionally burnout among healthcare workers is not a newly recognized crisis, and has been associated with higher rates of anxiety, depression, and substance abuse, COVID-19 has presented unique challenges, leading to increased mental health issues among healthcare workers. Although several previous publications have reported on the prevalence of stress and burnout among US healthcare workers, to our knowledge, the current study is the first systematic review to examine burnout specifically among surgical trainees and surgeons during the COVID-19 pandemic. We defined burnout rates among surgeons and identified personal and professional factors associated with burnout relative to the COVID-19 pandemic. Of note, reported burnout rates among surgical trainees and attending surgeons varied widely in the literature, likely due to the different study populations and the varied burnout assessment tools used. The most commonly reported personal factors contributing to burnout included fear of contracting/transmitting COVID-19 and being female whereas professional factors related to increased COVID-19 patient clinical load, limited work experience, reduction in operative cases and redeployment to COVID-19 wards. The COVID-19 pandemic was also noted to have a negative impact on surgical education including reduced hands-on experience and concern about completing case requirements.

Personal factors associated with burnout during COVID-19 were complex and multifactorial. Interestingly, data on the impact of having family/children were somewhat conflicting. Specifically, in the pre-pandemic setting, “having children” (especially older children) was associated with decreased rates of burnout. , Several studies similarly noted that “having children” was a protective factor against burnout during COVID-19. , , , Specifically, Khalafallah and colleagues reported that neurosurgeons who did not have children were at 3-times higher odds of burnout versus individuals who did have children. In contrast, other studies highlighted the additional stress associated with finding childcare, inconsistent schooling schedules, and worries about virus transmission among young children. , These data highlight how the COVID-19 specific context impacted the relative effect of children/family on individual risk of burnout among different individuals. In addition to children/family, female sex was also associated with a higher risk of COVID-19 related burnout across several medical subspecialties. Females may experience higher rates of burnout due to gender- related pay gap inequities, a lack of female role models, less advancement opportunities, sexual harassment, and poor work-life balance. The unique challenges experienced by providers and patients on COVID-19 wards, including the experience of illness and death without visitation from friends and family members, may put female surgeons at higher risk of emotional exhaustion and occupational burnout. Interestingly, Purvanova and Muros argued that it may be the expression of burnout, not the incidence of burnout itself that is different between genders. According to the authors, women are more likely to suffer from emotional exhaustion whereas men are more likely to describe depersonalization.

Burnout may be especially pervasive among physicians who are concerned about their work-place environment, as well as dissatisfied with their work-life balance.53, 54, 55 Contributors to burnout may include excessive workload, loss of autonomy, poor job satisfaction, as well as concerns for patient- and self-safety. , In the current study, several specific work-based factors were associated with an increased risk of burnout. For, excessive example patient workload, as well as fear of acquiring or transmitting the COVID-19 virus were significant contributors to burnout. , The need to redeploy surgical personnel from surgical services to COVID-19 wards was also an important factor associated with burnout among surgical trainees/surgeons, as was the cancellation of elective surgical cases. , , , Utilization of virtual didactic sessions dramatically increased, which had a varied impact on resident education. In addition, decreased time in the OR and more limited exposure to hands-on surgical training generated concern among trainees about meeting case requirements, graduation, and fellowship opportunities. To assuage these concerns, several national organizations made changes to accommodate surgical trainees. Specifically, for the 2019 to 20 academic year, the American Board of Surgery (ABS) lowered the minimum requirement to 44 weeks of clinical time and decreased the minimum case requirement by 10% (i.e., 850-765). , The American Board of Orthopedic Surgery (ABOS) gave the option to defer the written board exam if residents felt uncertain of a successful examination and modified the approach for the practice based oral examination. Longitudinal follow-up is needed to determine how these changes impact the global surgical workforce.

While no studies tested or aimed to develop interventions, several studies suggested ways to mitigate COVID-19 related burnout secondary to the COVID-19 pandemic, including formal PPE training, familiarization with pandemic protocols, and careful workload management. , Other recommendations to reduce or prevent burnout included spending time with family and friends, doing exercise or yoga, keeping pets and listening to music or painting. Within the context of training programs providing meals, residency mentorship and seeking support with increased mental breaks were suggested to alleviate burnout symptoms. , While helpful, these are individual-level interventions, whereas a comprehensive approach to mitigating burnout would also include organizational-level supports. Providing resources for providers mental health support and emergency childcare could be vital steps to maintaining a healthy workforce through the remainder of the pandemic. Additional qualitative research assessing specific needs of healthcare providers by role, specialty and other demographic/occupational factors would provide some much-needed insight.

Several limitations should be considered when interpreting results of the current study. As noted, the heterogeneity of tools used to measure burnout limited the ability to compare burnout rates across different publications and specialties. Additionally, while burnout was assessed in virtually every study with a validated tool, these measures have not been validated within the context of the COVID-19 pandemic. This manuscript aimed to reflect on the global experience of COIVD-19 on surgery, yet most publications included in the systematic review were also from high-income countries. As such, lower/middle-income countries, which had a very different experience with the COVID-19 pandemic due to more limited resources and inadequate PPE, were likely under-represented. In turn, data from the current study cannot be extrapolated to surgeons in those countries/clinical settings. Of note, the current review included studies performed between April 2020 and December 2021, during drastically different phases of disaster as originally defined by Zunin and Myers. The varying phases of the COVID-19 pandemic relative to the timing of any given study undoubtedly contributed to some heterogeneity in the data. Lastly, longitudinal data remain unavailable and therefore the long-term implications of burnout experienced by surgical trainees and surgeons during the COVID-19 pandemic remain unknown.

In conclusion, while there was variation among surgical trainees and surgeons across various studies, reported burnout associated with COVID-19 was high. In fact, numerous studies reported that as many as 1 in 2 surgical trainees and attending surgeons experienced COVID-19 related burnout. Intrinsic- (i.e., gender, age), family- (i.e., family/being married/having children or being single/not having children), as well as work-related extrinsic- (i.e., work-force deployment, risk of infection/spread, changes in educational format) factors were strongly associated with risk of burnout. As the threat of COVID-19 persists, it is important to note that health care workers continue to struggle with burnout and suffering. Interventions to ameliorate burnout among surgical trainees and surgeons should be informed by the factors identified in the current study and focus on those individuals most at risk including women and surgeons-in-training.
