Factors related to the resignation and migration of physicians in public health administration agencies using nationwide survey data in Japan

Abstract

Abstract Background Physicians in public health administration agencies (public health physicians: PHP) play important roles in public health; however, there are not enough such physicians in Japan. This study aimed to elucidate the factors related to the resignation and migration of PHPs using nationwide survey data. Methods Data from the Survey of Physicians, Dentists, and Pharmacists (2010, 2012, 2014, and 2016) were analyzed. The outcome was the resignation of PHPs or migration to public health administration agencies. The explanatory variables in the resignation analysis were age, sex, workplace, and board certification status. The type of work was added as an explanatory variable in the migration analysis, and clinical specialty was added to the clinical doctor-restricted analysis. The odds ratios (ORs) of the explanatory variables were calculated using generalized estimation equations. Results In the resignation analysis among PHPs, women had a significantly lower OR, whereas younger PHPs and those with board certifications had significantly higher ORs. In the migration to public health administration agencies analysis among medical doctors, women and those aged between 35 and 39 years had significantly higher ORs, but those with board certifications had significantly lower ORs. Hospital/clinic founders or directors had significantly lower ORs, but the clinic staff and ‘others/not working’ had significantly higher ORs. In the migration to public health administration agencies analysis among clinical physicians, those aged between 35 and 39 years had significantly higher ORs. Still, those with two or more board certifications had significantly lower ORs. Hospital/clinic founders or directors had significantly lower ORs, but the clinic staff had significantly higher ORs. Clinical doctors specializing in surgery and other specialties had significantly lower ORs, but those specializing in pediatrics and psychiatry/psychosomatic medicine had significantly higher ORs. Conclusions Having board certifications were significantly related to the resignation of PHPs and migration to public health administration agencies. Women migrated to public health administration agencies more than men and younger PHPs were more likely to resign. However, medical doctors aged between 35 and 39 years were more likely to migrate to public health administration agencies. Similarly, clinic staff, non-clinical physicians, and those whose specialties were pediatrics and psychiatry/psychosomatic medicine were more likely to migrate to public health administration agencies.
