본 연구는 일 종합병원 산부인과 환자를 대상으로 2013년 7월 1일 포괄수가제가 확대시행 전 후의 재원일수와 진료비를 비교 분석하여 포괄수가제 시행의 효과를 파악하고자 수행되었다. G광역시 소재 일 종합병원에서 2013년 1년간 산부인과 포괄수가제 질병군의 수술(자궁 및 자궁부속기 수술, 제왕절개술)을 받고 퇴원한 환자로, 행위별 수가제 적용 대상자는 2013년 1월~6월까지 입원한 환자 204명이었고, 포괄수가제 적용 대상자는 2013년 7월~12월까지 입원한 환자 194명으로 총 398명의 재원일수 및 진료비를 공분산분석(ANCOVA)하였다. 본 연구결과 재원일수는 행위별수가제에서 6.65(0.13)일, 포괄수가제에서 6.40(0.12)일로 감소하였고(p=0.013), 급여총진료비는 행위별수가제에서 1,726,333(46,331)원, 포괄수가제에서 2,271,115(37,069)으로 증가하였고(p<0.001), 보험자부담금은 행위별수가제에서 1,387,142(41,938)원, 포괄수가제에서 1,800,914(28,300)원으로 증가였다(p<0.001). 급여본인부담금은 행위별수가제에서 339,190(8,404)원, 포괄수가제에서 70,201(9,255)원으로 감소하였고(p<0.001), 비급여비용은 행위별수가제에서 642,243(22,039)원, 포괄수가제에서 197,507(9,091)원으로 감소하였고(p<0.001), 환자 총본인부담금도 행위별수가제에서 981,433(25,947)원, 포괄수가제에서 667,708(13,286)원으로 감소하였다(p<0.001). 본 연구결과 산부인과 환자에 대한 포괄수가제 적용은 재원일수, 비급여비용, 총본인부담금을 감소시켰고, 급여본인부담금, 보험자부담금, 급여총진료비를 증가시키는 효과를 보였다.
