Introduction As societies age globally, medical education faces the challenge of adapting to the evolving healthcare needs of an aging population. This study focuses on the education of medical residents in outpatient departments in Japan, a country with a rapidly aging society. The research aims to understand the perceptions and challenges medical residents face in outpatient management, highlighting the areas for potential improvement in their educational framework. Method This study involved first-year medical residents at Fuchu Hospital in Osaka, using thematic analysis based on relativist ontology and constructivist epistemology. Data were collected through field notes and reflection sheets, documenting residents’ interactions with patients, learning difficulties, and personal reflections. Semi-structured interviews were conducted to gain profound insights into their experiences and views on outpatient management education. Results Three main themes emerged from the analysis: The experience of continuity of care, the view regarding comprehensive management, and the gap between purposes and learning content. Residents expressed concerns about the limited opportunities for continuous patient care, leading to challenges in managing chronic diseases effectively. The focus on organ-specific specialties in acute care hospitals resulted in a fragmented understanding of patient care, particularly for elderly patients with multimorbidity. Furthermore, the study identified a discrepancy between the educational goals of outpatient management and the actual content delivered, highlighting the need for more observational experiences and practical guidance in outpatient settings. Conclusion The findings suggest a pressing need for a more structured, comprehensive, and personalized approach to outpatient management education for medical residents. As aging populations continue to grow, it is vital to equip medical professionals with the skills and knowledge to manage a wide range of patient conditions effectively. Improving the educational framework in outpatient departments can enhance patient care quality and prepare medical residents to meet the challenges of an aging society. This study contributes valuable insights into improving medical education in outpatient settings, particularly in aging societies like Japan.Copyright © 2024, Ohta et al.
