Program director (PD) tenure, continuity, and stability may enhance residency program quality, yet many PDs do not stay long in their positions. No prior study has taken a comprehensive census of departing PDs to determine reasons for leaving the role. This study aimed to survey all exiting family medicine (FM) PDs to identify decision factors contributing to their departure. From October 2021 to October 2022, we sent a web-based exit survey to all departing FM PDs. The survey asked departing PDs to rate the strength of 36 factors in the decision to exit the PD role in terms of job satisfaction, accomplishments, career choices, workload, preparation, expectations, and support. We used the Fisher exact test to assess all 36 decision factors and PD characteristics for significant associations with shorter or longer PD tenures. PDs submitted 73 surveys out of 109 invitations (67.0% response). We analyzed 68 with complete data. The median PD tenure was 5.6 years (mean 6.9 years). Most respondents (66/68, 97.1%) identified three or more strong factors in their decision to leave. The strongest factors reflected stable residency programs, an established succession plan, a desire for more personal/family time, and a sense that the time was right. PDs with tenures longer than 3 years were more likely to have completed the National Institute for Program Director Development (P=.001). PDs leave the position for multiple reasons, often positive, and not necessarily due to lack of support and preparation. Further exploration of decision factors may inform strategies to support PDs in their positions.
