Abstract

Purpose: There is a growing concern for the cost management of medical institutions. The purpose of this study was to estimate Activity-Based Costing (ABC) for dental implant cost. ABC refers to allocating resources or cost based on the activities of services. Materials and methods: A dental institution located in the metropolitan area was selected in this study. The tax accounting data of the institution were utilized to confirm total cost, and the institution was asked to make out clinical activities to figure out what activities were carried out. The direct cost and indirect cost for dental implant were separately estimated, and cost driver was analyzed to estimate the indirect cost accurately. Results: The rates of the direct and indirect cost respectively stood at 35.8 and 49.5 percent. The cost for a dental implant was found to be approximately 1,579 won, and the cost of prosthetic surgery and treatment that included implant surgery accounted for the largest portion of the cost, which was 470 thousand won (30%). And the weight of training and education on dentistry was relatively higher than that of the other kinds of treatment. Conclusion: In order to ensure accurate and scientific costing for dental implant, not only direct medical procedure but every pre- and post-procedure activity should fully be taken into account. Pre-activities, post-activities, education and training are included in the indirect cost, but all these activities are mandatory and associated with the quality of treatment and the satisfaction level of patients.

연구 목적: 의료환경의 변화에 따라 새로운 의료관리에 대한 필요성과 함께 의료기관의 원가관리에 대한 관심이 증가되었다. 본 연구는 치과의료기관에서 빈번하게 제공되는 치과 임플란트 서비스를 직원의 활동에 근거하여 자원 또는 원가를 배부하는 활동기준원가(Activity-Based Cost, ABC) 방법을 적용하여 원가를 산정하기 위해 시행되었다. 연구 대상 및 방법: 수도권 소재의 A 치과의료기관을 대상으로 치과 임플란트 원가산정을 실시하였다. 해당 기관의 총비용을 확인하기 위해 1사분기 세무회계자료를 사용하였고 기관 내에서 이루어지는 활동을 파악하기 위하여 활동분석표 작성을 요청하였다. 자료를 바탕으로 치과 임플란트에 해당하는 직접원가와 간접원가를 분리하고, 간접원가의 왜곡을 최소화하기 위해 원가동인(Cost driver)을 파악하여 활동별로 비용을 배분하는 활동기준원가 분석을 실시하였다. 결과:치과 임플란트 원가를 직접비와 간접비로 나누어 비교한 결과 각각 35.8%, 49.5%로 나타났다. 치과 임플란트 1개당 원가는 1,579천원 정도로 산정되었고, 임플란트 수술 및 시술 전 후 활동이 포함된 보철 시술 진료영역에 47만원(30%)이 소요되어 가장 많은 부분을 차지하였다. 연수 및 치과학 교육 등의 활동도 기타 진료에 비해 상대적으로 높은 비중을 나타내었다. 결론: 과학적인 치과 임플란트의 수가 산정을 위해서 치과 임플란트와 관련된 직접적인 진료 술식 이외에 시술 전 후 준비활동 등에 대한 고려가 충분히 이루어져야 한다. 임플란트 시술 전 후의 활동 및 교육, 연수활동 등은 간접비에 포함되는 부분이나 진료의 질을 담보하고 환자의 만족도를 향상시키기 위해 반드시 필요할 활동으로 이러한 활동들을 고려한 합리적 수가 산정이 필요하다.
