Abstract

Background: Primary care facilities are the base for hypercholesterolemia treatment. However, data regarding the effectiveness of lipid management in primary care are lacking.

Methods and results: To evaluate lipid management in the primary care setting in China, we compared patients' characteristics and lipid management outcomes between 6100 outpatients treated at primary care versus 19,217 patients in non-primary settings using data from the DYSlipidemia International Study-China (DYSIS-CHINA). Compared to patients treated at non-primary hospitals, patients who received treatment at primary settings were younger, thinner, and were more likely to be female and to have a family history of premature CVD. Overall, 26.8% of very high-risk and 40.8% of high-risk patients achieved the LDL-C target with primary care treatment, whereas these target rates were 41.2% (p<0.001) and 58.6% (p<0.001), respectively, among patients treated at non-primary hospitals. High-dose statin therapy was underused in primary care patients compared to non-primary hospital patients (p<0.001). Logistic regression analysis showed that female gender, diabetes, and obesity were negative factors, whereas life-style modification and use of high-dose statin (40mg/d simvastatin equivalent) were favorable factors in predicting LDL-C target attainment in the primary care setting.

Conclusion: Sedentary life style, alcohol drinking, and use of suboptimal statin dosage are key factors that unfavorably affect the LDL-C target rate among patients treated at primary care facilities in China. Sufficient training for primary care physicians regarding proper statin use and support for the combined use of a statin with ezetimibe could promote LDL-C target attainment in primary care.
