There is systematic evidence that community-based education is effective in the recruitment of rural physicians to remote communities. However, various obstacles may exist that prevent rural physicians from sustaining their mentoring activities. The aim of this study was to explore ways for rural physicians to overcome such adversities and continue their mentoring activities. We interviewed four nominated physicians (all male, mean age 48 years) based in Hokkaido, Japan, who practiced in an area with less than 10,000 inhabitants. Semi-structured interviews of approximately 60 minutes were performed and focused on topics rural physicians’ found necessary for their teaching activities. All interviews were tape-recorded and transcribed, the verbatim transcripts were analyzed and repeated themes were identified. Three themes that emerged as needs were 1. sustained significant human relationship, including the formation of a network between students and university faculty, as well as developing partnerships with many community relationships, or other medical professions; 2. intrinsic motivations and satisfaction, including pleasure in mentoring the younger generations; and 3. rewards, including financial compensation. Rural physicians as preceptors require nonremunerative, intrinsic motivational factors, such as a sense of satisfaction regarding the education of medical students and being able to relate to residents and others health-care professions, when pursuing their educational activities. To support them, focusing only on monetary facets may be unsuccessful in encouraging them to continue their educational work.
