Abstract
BACKGROUND: In Japan, local governments have rural clinics designated for areas without physicians (RCDA) to secure physicians for rural medical care. Moreover, a medical policy of dispatching physicians between the RCDA and core hospitals for rural areas (CHRA) exists. This study aimed to assess the actual situation of physician migration from RCDAs and those who migrated, and examine the factors associated with their migration. METHODS: This retrospective cohort study used biennial national physicians' survey data from 2012 to 2018. It targeted physicians who worked at RCDAs in 2012 and participated in all four surveys (n = 510). The physicians were divided into two groups. One group consisted of physicians who worked continuously at the RCDA over the four study periods (retained physicians, n = 278), and the other included physicians who migrated to other institutions midway through the study period (migrated physicians, n = 232). We tracked the types of facilities where RCDA physicians worked from 2012 to 2018, also examined the factors associated with their migration. RESULTS: Among physicians from RCDAs who migrated to other institutions (n = 151) between 2012 and 2014, many migrated to hospitals (n = 87/151, 57.6%), and some migrated to CHRA (n = 35/87, 40.2%). Physicians in their 40s (Hazard ratio 0.32 [95% CI 0.19-0.55]), 50s (0.20 [0.11-0.35]), and over 60 years (0.33 [0.20-0.56]) were more likely to remain at RCDAs. Changes in their area of practice (1.82 [1.34-2.45]) and an increase in the number of board certifications held by physicians between 2012 and 2018 (1.50 [1.09-2.06]) were associated with migration. CONCLUSIONS: Many migrating physicians choose to work at hospitals after migrating from RCDAs. It was seemed that the physician dispatch system between RCDA and CHRA has been a measure to secure physicians in rural areas. Young age, obtaining board certification, and changes in areas of practice were associated with physician migration from RCDAs.
