The Transition to Independence: A Longitudinal Qualitative Study on Drivers of Burnout and Resilience in Japanese Medical Residents

Background/Objective The transition from postgraduate residency to independent practice is a critical period in medical education, often accompanied by heightened clinical responsibilities. While adequate workload and stress are essential for professional growth, excessive demands can precipitate burnout. This study explores the underlying drivers of burnout and the development of resilience among resident physicians in Japan during this transitional phase. Methods A longitudinal qualitative study was conducted at an urban hospital in Japan. Eight resident physicians participated in semi-structured, in-depth interviews at the end of their two-year training in 2022, followed by a subsequent interview in 2024 after transitioning to their specialties. Additionally, senior attending physicians and support center staff were surveyed to triangulate the findings. Audio data was transcribed and analyzed using a grounded theory approach via NVivo 14. Results Typical burnout was rarely observed during the initial two-year residency, as residents perceived their training environment as highly protected, often citing a lack of autonomy and primary responsibility. However, the follow-up interviews revealed that the abrupt transition to independent practice exposed them to heavy responsibilities and complex patient management, triggering delayed burnout episodes. Crucially, residents who experienced burnout reported that overcoming these challenges ultimately enhanced their professional resilience. Peer communication and appropriate mentoring were identified as vital mitigating factors, whereas simple reductions in working hours were insufficient to prevent emotional exhaustion. Conclusion Burnout among early-career physicians is strongly associated with the abrupt shift in clinical responsibility during the transition to independent practice, rather than the absolute volume of workload during initial training. While appropriate stress is a necessary catalyst for professional development, stakeholders must design transition programs that provide graduated autonomy, robust peer support, and ongoing mentoring to foster resilience and prevent burnout in the post-residency period.
