Abstract
Objective: This study examined the long-term effectiveness of the national diabetes quality assessment program (NDQAP) in diabetes.
Research design and methods: From the Health Insurance Review and Assessment Service database, 399,984 individuals with diabetes who visited a primary care clinic from 1 July 2012 to 30 June 2013 were included and followed up until 31 May 2021. The NDQAP included five quality assessment indicators: regular outpatient visits, continuity of prescriptions, regular testing of glycated hemoglobin and lipids, and regular fundus examination. Cox proportional hazards models estimated hazard ratios (HRs) and 95% confidence intervals (CIs) for diabetes complications and all-cause mortality by the achievement of quality assessment indicators.
Results: During the mean follow-up duration of 7.6 ± 1.8 years, 20,054 cases (5.0%) of proliferative diabetic retinopathy (PDR), 6,281 end-stage kidney diseases (ESKD; 1.6%), 1,943 amputations (0.5%), 9,706 myocardial infarctions (MIs; 2.4%), 26,975 strokes (6.7%), and 35,799 all-cause mortality (8.9%) occurred. Each achievement of quality assessment indicator was associated with a decreased risk of diabetes complications and all-cause mortality. Individuals who were managed in high-quality institutions had a lower risk of PDR (HR 0.82; 95% CI 0.80-0.85), ESKD (HR 0.77; 95% CI 0.73-0.81), amputation (HR 0.75; 95% CI 0.69-0.83), MI (HR 0.85; 95% CI 0.82-0.89), stroke (HR 0.86; 95% CI 0.84-0.88), and all-cause mortality (HR 0.96; 95% CI 0.94-0.98) than those who were not managed in high-quality institutions.
Conclusions: In Korea, the achievement of NDQAP indicators was associated with a decreased risk of diabetes complications and all-cause mortality.
