Six in 10 US physicians reported burnout- a syndrome resulting from poorly managed chronic workplace stress characterized by feelings of exhaustion, increased mental distance from work and reduced professional efficacy. From February to July 2023, an electronic survey exploring burnout, coping mechanisms and intended retention in the military was disseminated to military physician alumni of the Uniformed Services University of the Health Sciences (who graduated between 2003-2018). A total of 116 alumni from (Air Force (42%), Army (29%) and Navy (29%)) respondents were mostly physicians (94%), married (86%), white (82%), males (64%), and deployed at least once (57%) with >10 years of service (82%) and clinical experience (38%) respectively. About a third worked over 60 hours/ week (29%) or in a hectic/chaotic environment (35%) while 43% claimed they were overworked. Only about a third had favorable perceptions about their work (36%) while 47% noted the presence of five or more negative job-related symptoms such as insomnia (60%), apathy (62%), forgetfulness (60%). Only a third of respondents typically demonstrated positive coping approaches to stress in general (34%). Several providers currently had definite, unrelenting or complete burnout (63%) or ranked highly on the burnout experience scale (49%). After controlling for demographic and psychosocial factors, burnout rates were significantly higher among providers working in hectic environments (Adjusted Odds Ratio (AOR): 8.67, 95% CI: 1.76-42.59), as well as those with negative job-related symptoms (AOR: 7.36, 95% CI: 1.78-30.29). On the other hand, burnout rates were lower among Army (AOR: 0.12, 95% CI: 0.02-0.66) and Navy (AOR: 0.03; 95% CI: 0.00-0.24 ) health providers compared to the Air Force. Burnout was also lower among health providers with over five years versus less experience (AOR: 0.08; 95% CI: 0.01- 0.58) and among providers with positive coping approaches to stress in general (AOR: 0.12, 95% CI: 0.24-0.60). Respondents’ coping mechanisms in response to burnout/stress were observed at the individual (exercise (74%), taking time off (68%)) and interpersonal (time with friends/family or confiding in others (71% each)). Few respondents noted organizational efforts to combat burnout/stress including social events (40%) and workshops (16%). Intended retention among respondents was low. Two-thirds (67%) thought of quitting their current job in the past year and only 42% expressed a desire to remain in the military until retirement. Study findings may corroborate the US Surgeon General advisory on the ongoing health worker burnout and projected shortage of physicians by 2033. Burnout and among military health workers may affect the readiness, including access to and quality of much needed health services. Study findings also suggest that multi-level interventions are needed in response to the intense professional pressure of health service provision. Such interventions need to be contextually relevant as military health providers undergo combat training and deployments, in addition to their own personal or household stress. Subsequent research aims to identify and test feasible solutions that can be implemented at scale.
