Assessing the medium-term effects of a community-based medical education program with homestay practice: a cohort study in Tamba, Japan

Introduction This study intended to evaluate the medium-term effectiveness of a community-based medical education (CBME) program and to determine the program’s influence on the application rates of regional-quota students seeking to become residents in Tamba, Japan.Materials and Methods We conducted a cohort study of regional-quota students. Exposure factors included (1) experience compared to no experience of CBME in the Tamba area; (2) CBME experience compared to no experience in Tamba in the senior years (4–6 years of medical school) and experience in the junior years (1–3 years of medical school); and (3) experience in the senior years compared with those in the junior years. Outcome measures were applications to become a medical resident and actually becoming a medical resident at the Hyogo Prefectural Tamba Medical Center.Results Of 94 participants, 58 (61.7%) were male and 37 students (39.4%) had previous CBME experience in the Tamba area. In applying to become a resident at the Hyogo Prefectural Tamba Medical Center, students who had experienced CBME in the Tamba area in their senior years had significantly higher adjusted risk ratios compared to those who experienced it in their junior years. Regarding applications to become a resident, students who had experienced CBME in the Tamba area in their senior years had a significantly higher adjusted risk ratio than students who had not experienced CBME and students who had experienced CBME in their junior years.Conclusions There was a statistically significant application rate for residency programs among medical students who participated in the CBME program in their senior years compared with those who did not. This is the first study to confirm the medium-term effects of CBME after several years in short-term CBME programs of three days and two nights.
