Workplace microaggressions are a longstanding but understudied problem in the surgical specialties. Microaggressions in health care are linked to negative emotional and physical health outcomes and can contribute to burnout and suboptimal delivery of patient care. They also negatively impact recruitment, retention, and promotion, which often results in attrition. Further attrition at the time of an impending surgical workforce shortage risks compromising the delivery of health care to the diverse US population, and may jeopardize the financial stability of health care organizations. To date, studies on microaggressions have consisted of small focus groups comprising women faculty or trainees at a single institution. To our knowledge, there are no large, multiorganizational, gender-inclusive studies on microaggressions experienced by practicing surgeons. This study aimed to examine the demographic and occupational characteristics of surgeons who do and do not report experiencing workplace microaggressions and whether these experiences would influence a decision to pursue a career in surgery again. We developed and internally validated a web-based survey to assess surgeon experiences with microaggressions and the associated sequelae. The survey was distributed through a convenience sample of 9 American College of Surgeons online Communities from November 2022 to January 2023. All American College of Surgeons Communities comprised members who had completed residency or fellowship training and had experience in the surgical workforce. The survey contained demographic, occupational, and validated microaggression items. Analyses include descriptive and chi-square statistics, t tests, and bivariable and multivariable logistic regression. The survey was completed by 377 American College of Surgeons members with the following characteristics: working as a surgeon (80.9%), non-Hispanic White (71.8%), general surgeons (71.0%), aged ≥50 years (67.4%), fellowship-trained (61.0%), and women (58.4%). A total of 254 (67.4%) respondents reported experiencing microaggressions. Younger surgeons (P=.002), women (P<.001), and fellowship-trained surgeons (P=.001) were more likely to report experiencing microaggressions than their counterparts. Surgeons working in academic medical centers or health care systems with teaching responsibilities were more likely to experience microaggressions than those in private practice (P<.01). Surgeons currently working as a surgeon or those who are unable to work reported more experience with microaggressions (P=.003). There was no difference in microaggressions experienced among respondents based on surgical specialty, race/ethnicity, or whether the surgeons reported having a disability. In multivariable logistic regression, women had higher odds of experiencing microaggressions compared with men (adjusted odds ratio, 15.9; 95% confidence interval, 7.7-32.8), and surgeons in private practice had significantly lower odds of experiencing microaggressions compared with surgeons in academic medicine (adjusted odds ratio, 0.3; 95% confidence interval, 0.1-0.8) or in health care systems with teaching responsibilities (adjusted odds ratio, 0.2; 95% confidence interval, 0.1-0.6). Among surgeons responding to an online survey, respondents reporting microaggressions were less likely to say that they would choose a career in surgery again (P<.001). Surgeons reporting experience with microaggressions represent a diverse range of surgical specialties and subspecialties. With the continued expansion of surgeon gender and race/ethnicity representation, deliberate efforts to address and eliminate workplace microaggressions could have broad implications for improving recruitment and retention of surgeons.
