Abstract

Objectives: The purpose of this study was to analyze whether there are differences in medical expenses according to medical security type in the use of medical services with high disease burden such as coronary intervention. Methods: Chi-square test and covariance analysis(ANCOVA) were conducted to identify the differences in the characteristics and costs according to medical security type of 1,904 patients who underwent coronary intervention in a university hospital from 2011 to 2012. Hierarchical regression analysis was conducted to determine whether the cost affects medical expenses. Results: In the medical aid group, the proportion of women, those without a job, those without a spouse, and those who received hemodialysis was high, length of stay was high, patients using the emergency room and those who died was high. The medical aid patients were significantly higher in the non-benefit medical expenses, optional medical expenses, physician and admission, meals, medications and injections. National health insurance patients were significantly higher in procedure. The medical security type was found to be significant as a variable affecting the medical expenses. Conclusions: Provision of medical expenses should be managed in advance by providing prevention and education services for the vulnerable, and care services in the region should be provided to suppress the occurrence of medical expenses due to the increase in the number of days spent. In addition, it is necessary to support medical expenses to prevent unsatisfactory medical services from occurring for non-benefit and optional care.

의료급여수급권자는 낮은 본인부담으로 인해 공급자에 의한 유발의료수요가 발생하거나 수급권자의 도덕적 해이가 발생하여, 의료서비스 남용으로 인한 의료급여 재정의 건전성을 저해한다는 지적을 받고 있다. 이 연구는 관상동맥중재술과 같은 질병부담이 높은 의료서비스 이용에 있어서 우리나라의 대표적인 의료보장형태인 건강보험환자와 의료급여환자의 진료비 발생 구조를 분석하여 진료비 관리의 정책적 방향을 제시하고자 수행되었다. 관상동맥중재술 시행을 받은 환자에서 의료보장형태에 따라 의료서비스 이용 양상 및 진료비 구조에 차이가 있었다. 의료급여군이 건강보험군에 비해 재원일수가 길고, 응급실을 경유하여 입원한 환자의 비율이 높았으며, 비급여진료비, 선택진료비, 일당 비급여진료비가 적게 발생하였고, 재원일수와 관련 있는 진찰료 및 입원료, 식대, 투약 및 주사료 항목에서는 총 진료비가 많이 발생하였다. 따라서, 국가차원의 효율적인 진료비 관리를 위해서 취약계층에 대한 예방과 교육서비스를 제공하여 사전적 진료비관리가 이루어져야 하며, 의료급여 환자의 재원일수 증가에 따른 급여진료비 발생을 관리하는 전략이 필요할 것으로 보인다. 또한, 비급여 진료비에 있어서 의료급여환자의 미충족 의료서비스가 발생하지 않도록 의료비 지원방안도 마련되어야 한다.
