Abstract

In this study, issues related to changes in base year, which have controversial effects on fees in service contracts, were reviewed. In this regard, sensitivity analysis was conducted on the effects of changes in base year on conversion factor by type. The benefits and disadvantages of each specific type of medical institution were examined. Main conclusions are as follows. First, changing the base year to be closer to the present time had a beneficial effect on the conversion factor of hospitals. Second, changing the base year to be closer to the current point of time had an adverse effect on the conversion factor of pharmacies and clinics and had a significant adverse effect on clinics. Third, assuming that a single conversion factor is collectively applied to all types, a favorable effect occurred in all cases when the base year was changed to be closer to the present time. Base year changes can bring about conflicts of interest between insurer and providers, and within providers. Therefore, changing the base year should be pursued upon mutual agreement on a reasonable basis for resource allocation. In addition, it is necessary to provide incentives for temporary compensation for the types of losses incurred.

본 연구에서는 최근 수가계약 과정에서 논란이 되고 있는 기준연도 변경과 관련된 이슈를 살펴보았다. 이와 관련하여 기준연도 변경이 유형별 환산지수에 미치는 영향과 관련해 민감도분석을 실시하였다. 그리고 기준연도변경이 특정유형에 미치는 유리하거나 불리한 상황을 분석하였다. 또한 단일 환산지수 체계라고 가정하는 경우 기준연도 변경에 따른 환산지수 변동도 고찰하였다. 본 연구의 주요한 결론은 다음과 같다. 첫째, 기준연도를 현재시점에 가깝게 변경하는 경우 병원의 환산지수에는 유리한 효과가 발생한다. 둘째, 기준연도를 현재 시점에 가깝게 변경하는 경우 약국과 의원의 환산지수에는 불리한 효과가 발생하며 의원의 경우 불리한 효과가 크다. 셋째, 유형 전체에 단일 환산지수를 일괄적으로 적용한다고 가정하면 기준연도를 현재 시점에 가깝게 변경하는 경우 모든 유형에 유리한 효과가 발생한다. 기준연도 변동은 보험자와 의료공급자, 의료공급자 사이에 이해충돌을 가지고 올 수 있다. 따라서 자원 배분의 합리적인 근거를 바탕으로 상호 합의에 추진되어야 하며 손실이 초래되는 유형에 대해서는 한시적 보상을 위한 인센티브를 제시할 필요가 있다.
