Effects of Usual Source of Care by Patients with Diabetes on Use of Medical Service and Medical Expenses

국문 초록 (Abstract)

목적: 상용치료원(usual source of care)은 아프거나 건강문제에 대한 조언이 필요할 때 주로 방문하는 특정 개인의원, 보건소, 혹은 기타 장소로, 상용치료원 보유는 예방서비스를 제공을 더 받게 되며, 보건의료에 대한 전반적인 만족도가 높고, 입원율을 감소시키며 의료급여자의 의료비를 감소시킬 수 있다. 이 연구에서는 당뇨병을 보유하고 있는 20세 이상을 대상으로 상용치료원 보유 여부에 따른 대상자의 현황을 파악하고, 의료이용 횟수 및 의료비의 차이와 이에 영향을 미치는 특성을 분석하였다. 방법: 이 연구는 제7차 한국의료패널 자료를 이용하였다. 상용치료원 보유여부에 따른 의료이용 횟수와 의료비를 비교하기 위해 분산분석을 실시하였으며, 상용치료원 유형에 따른 의료이용 횟수와 의료비용에 영향을 미치는 요인을 파악하기 위해 Tobit 분석을 수행하였다. 결과: Tobit 분석결과, 상용치료원을 보유한 경우 보유하지 않은 경우보다 외래의료비는 증가했으나 입원의료비는 감소하였다. 상용치료원을 보유한 경우 보유하지 않은 경우보다 외래이용횟수와 입원횟수가 증가했으나 통계적으로 유의하지 않았다. 함의: 지속적이고 포괄적인 의료서비스가 제공되는 상용치료원을 당뇨병 환자들이 보유하게 되면, 외래 예방서비스의 이용을 통해 장기적으로 입원의료비의 감소를 기대할 수 있을 것이다.

Purposes: Diabetes is a metabolic disorder that requires continuous care in order to prevent complications, as it can impose a critical burden on families and society due to various complications, including terminal renal failure, non-traumatic lower extremity amputation, and adult blindness. The usual sources of care are "specified private clinics, public health centers, or other facilities to visit when ill or when health-related advice is needed". These usual sources of care offer preventative services, have a high overall satisfaction rate in terms of public health care, and decrease the inpatient rates and medical costs of medical aid recipients. This study analyzed the current status of diabetic patients over 20 years of age based on their possession of a usual source of care, and the effects of this possession on the frequency of their medical service usage and its costs. Methodology: Based on data from the 7th Korea Health Panel, a Tobit analysis was used to analyze the different factors that can affect the frequency of medical service usage and its costs for diabetic patients with and without a usual source of care. Findings: The medical costs of diabetic patients with a usual source of care decreased in terms of inpatient, and the outpatient visits and inpatient costs of the group with a usual source of care in the form of a mainly-visiting doctor decreased more than those of the group with a mainly-visiting medical institution only. Practical Implications: Having a usual source of care can increase the treatment continuity, leading to reduced inpatient, and having a mainly-visiting doctor as the usual source of care further increases the treatment continuity. Based on these results, a new policy is needed to increase and strengthen diabetic patients? possession of a usual source of care.
