DRG 지불제도 적용수술에 투입되는 재료비 산출 및 분석에 관한 연구

Abstract

Purpose: This research analyzed the material cost of the operation adapted to DRG payment system. Method: This research was performed from April. 1, 2003 to Oct. 27, 2003 for 342 patients. We analyzed the output of operation material cost and the resulting factor of the difference by the research table about consumed materials. The 8 groups of operation that adapted in DRG system were divided into 12 lists and 3 factors ; disease-dependent factor, operatordependent factor, and staff-dependent factor which induced the cost difference. Result: The most expensive operation was cataract surgery( 482,746) and the cheapest surgery was tonsillectomy( 7,217). Cesarean sections represented the greatest difference between the highest and the lowest cost, about 152,177, and tonsillectomy represented the smallest difference, about 3,128. The factors contributing to the difference were the operator-dependent factor(46.7%), the disease-dependent factor(37.5%), and the staff-dependent factor(15.8%). Conclusion: It is expected that the material cost of the operation can be reduced when all operator change their cognition about DRG payment system and voluntarily participate to reduce the cost of material.
