Development of Casemix Based Evaluation System in Japan

抄録

In order to ameliorate the transparency of acute in-patient services in Japan, we have developed the Japanese original casemix system, so called DPC (Diagnosis Procedure Combination) after the two years’ intensive researches of other countries. This casemix system has been used for payment of acute care hospital since 2003. As the DPC system has been organized based on the already existed Fee-for-service system, its application for payment has been smoothly conducted. The introduction of DPC system has ameliorated the transparency of clinical activities and facilitated the managerial innovation of acute care hospital both at facility level and regional level. In this article, the authors would like to introduce the overview of Japanese casemix system.
