초록

본 연구는 고혈압 환자의 일차의료 지속성 수준을 파악하고, 일차 의료 지속성 수준이 환자의 입원 및 응급실이용에 미치는 영향을 실증하는 융복합적 결과연구(outcome research)이다. 후향적 코호트(retrospective cohort study)연구로써 건강보험 청구자료를 사용하여 고혈압을 주상병으로 진단받은 315,791명을 3년 동안 추척 관찰하였다. 지속성지표는 MFPC, MMCI, COC를 적용하였고 결과변수는 입원 및 응급실 방문을 고려하였다. 일차의료의 지속성 수준과 입원 및 응급실이용의 위험도를 분석한 결과, 지속성 낮은 군이 지속성 높은 군 보다 입원 할 위험도가 1.655배(95% CI: 1.547-1.771), 응급실이용은 1.669배(95% CI: 1.465-1.903) 높았다. 따라서 우리나라 고혈압 환자의 진료지속성을 높이는 정책은 급증하는 만성질환 의료비를 줄일 수 있을 것이다.

This paper examines the level of the primary care continuity for patients with high blood pressure and the effects of the primary care continuity on their convergence health outcomes. We conducted a retrospective cohort study. A total of 315,791 patients who had received new diagnoses of hypertension. We determined standard indices of continuity of care-MFPC, MMCI, and COC and evaluated their association with study outcomes over three years of follow-up. Outcome measures included hospitalization and emergency room visits. The result of the primary care continuity levels and hazard ratios of health outcome showed that, comparing continuity group, non-continuity group had higher rates of hospitalization by 1.655(95% CI: 1.547-1.771) and emergency room visits by 1.669(95% CI: 1.465-1.903). This paper argues that medical costs of chronic diseases will reduce if low continuity of care turns into high continuity of care.
