Background: Supplier induced demand (SID) indicates the case when doctors increase the demand of the patients, following their (physicians') own best interests rather than patients'. This may occur when asymmetry of information exists between suppliers and consumers. This study aims to confirm whether SID exists in the Korean setting, particularly by dividing SID into both 'induced demand effect' and 'availability effect.' Methods: Induced demand effect and availability effect are differentiated following Carlsen & Grytten's theoretical frame which divides doctor density regions into high and low ones. Results: Positive correlation between doctors' density and utilization of their services was found, which could be interpreted as 'availability effect.' Conclusion: The result suggests that additional medical use for additional doctor, particularly in the area of low doctor density, can be interpreted to occur to meet the basic medical need of the people rather than as a result of unnecessary induced demand. It is important to make more medical doctors provided and to distribute them appropriately across the region in such a country like Korea where doctor's density is relatively low.

Background: A need arises to efficiently control health expenditure for medical aid due to a sharp increase in medical aid expenditure. This study experimently analyzes the impact of physician behavior on medical use for medical aid beneficiaries using supplier induced demand (SID) theory. Methods: This study looks into analyze SID effect using expenditure factor analysis of medical aid for the years between 2003 and 2010 in comparison with health insurance. Moreover, this study analyzes the existence and scale of SID using econometrics modeling with panel data on 16 cities and provinces's health expenditure data for medical aid from 2003 1/4 to 2010 4/4. Results: This study finds that the growth rate of visit days per capita and treatment amount per visit days for medical aid is higher than health insurance. Furthermore, the result of econometrics modeling analysis shows the existence of SID in general hospital, hospital, clinic, oriental clinic. Conclusion: In order to efficiently control expenditure for medical aid, it is required to reinforce macro polices such as the introduction of 'target management' and micro policies such as the strengthen of management on medical institutes in the perspective of suppliers as well as regulations of demanders.

본 연구는 의과 일부 상병에 국한된 지역간 의료이용변이 연구의 범위를 한방으로 확대하여 다양한 실증적 연구기반을 마련하고 의과 상병의 지역간 의료이용변이가 한방에서도 존재하는지, 존재한다면 그 요인은 무엇인지를 파악하여 한방 의료서비스의 합리적 이용을 위한 정책수립에 필요한 기초 자료를 제공하는데 그 목적이 있다. 2010~2011년 건강보험 자료에서 의과, 한방외래 다빈도 10대 상병을 선정하고 86개 군 지역을 대상으로 지역 간 의료이용 변이여부를 분석하였다. 분석결과 한방에서도 지역별의료이용변이가 존재하는 것으로 나타났는데 내원일당진료비는 공급자측면 보다는 수요자특성이 주요한 요인으로 작용하였고 수진자당진료비는 공급자와 수요자특성이 동시에 주요한 요인으로 작용하였다. 따라서 한방 의료서비스의 합리적 이용을 위한 의료의 과다이용과 미 충족 방지를 위해 한방 의료서비스 표준화, 한방의료 역할강화, 올바른 의료이용과 불필요한 의료행위를 줄이기 위한 정보제공 및 정보공유 확대정책이 필요하다.
