The healthcare workforce policy planner should consider future dynamic changes in physician numbers. The purpose of this study was to propose a physician supply forecasting methodology by applying system dynamics modeling to estimate future absolute and relative numbers of physicians. Method: We constructed a forecasting model using a system dynamics approach. Forecasting the number of physician was performed for all clinical physician and OB/GYN specialists. Moreover, we conducted evaluation of sufficiency for the number of physicians and sensitivity analysis. Result & conclusion: As a result, it was forecast that the number of physicians would increase during 2008-2030 and the shortage would resolve at 2026 for all clinical physicians. However, the shortage would not resolve for the period covered. This suggests a need for measures for reconsidering the allocation system of new entry physicians to resolve maldistribution between medical departments, in addition, for increasing the overall number of clinical physicians.Biomed central ltdJournal Articleapplication/pdfhttp://hdl.handle.net/2115/53394https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/53394/1/1478-4491-11-41.pdf1478-4491AA12050850Human resources for health111102013-08-27enginfo:doi/10.1186/1478-4491-11-41http://creativecommons.org/licenses/by/2.0/publisher
