Studies have shown the importance of managing chronic diseases, such as cardiovascular disease (CVD), at the primary treatment level. Here, we aimed to evaluate the association between medical treatment institutions and health outcomes in patients with dyslipidemia, a major risk of CVD, to provide evidence for increasing chronic disease management at the primary care level in Korea. We used National Health Insurance Sampling cohort data, of which 37 506 patients were newly diagnosed with dyslipidemia during 2009-14. CVD risk and changes in serum cholesterol level after dyslipidemia diagnosis were outcome variable examined. A generalized estimating equation model was used to identify associations between initial medical institution, CVD risk and changes in serum cholesterol levels. The Cox proportional-hazard ratio was used to assess the association between initial medical institutions and detailed CVD risk. Subgroup analyses were conducted to assess CVD risk following treatment with prescription medication. Our analyses demonstrate that CVD risk was lower at primary care-level community health centers and clinics compared to tertiary hospitals, with a statistically significant difference observed in clinics. Ischemic heart disease was lower at community health centers and clinics. However, all medical institution types were associated with significantly lower serum cholesterol levels compared to the baseline. Management of patients with dyslipidemia at primary care institutions was associated with reduced CVD risk and decreased serum cholesterol levels. Therefore, policymakers should strengthen the quality of healthcare at primary care institutions and educate patients that these institutions are appropriate for managing chronic disease. © The Author(s) 2020.
