치과의사의 진료행태와 지표연동자율개선제의 중재활동 효과

Abstract

The Health Insurance Review and Assessment Service has implemented the Indicator Linkage Management System (ILMS), which is designed to increase quality of care in healthcare organizations. We analyzed the effects of intervention activities under ILMS on dentists’ practice patterns and explored the factors affect the practice patterns. The visit index and costliness index were used to measure practice patterns. We used a randomized control group pre-post study design. The intervention activities were applied during the second quarter in 2016. The indices in the first quarter in 2016 were compared to the fourth quarter. The total of 994 dental clinics in Seoul metropolitan city were selected as the study sample. We used t-test for the pre-post comparison and performed multivariate ordinary least squares regression analysis to determine the predictors of dentists’ practice patterns. Both indices decreased after the intervention activities were applied. The most significant predictors of practice patterns were the types and the cumulative number of intervention activities. The findings of the study show that intervention activities under ILMS leads to the changes in dentists’ practice patterns. Results have implications for efforts to influence practice patterns in dental clinics and administering the ILMS standards in healthcare organizations.
