Abstract

Despite strong evidence for the use of statins for patients with atherosclerotic cardiovascular disease (ASCVD), statin prescription is still suboptimal. We aimed to determine the rates and factors that influence statin prescription using national survey data. This is a cross-sectional retrospective study on 8,468 patients with clinical ASCVD who were drawn from the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey from years 2011 to 2015. Survey-weighted analysis was conducted to estimate weighted prevalence and odds ratios for statin prescription. There was a significant increase in statin prescription from the years 2011 to 2015. Nevertheless, only 52% of ASCVD patients (55.4% in coronary heart disease and 37.7% in noncoronary heart disease) were prescribed a statin. Based on multivariable regression analysis, after adjusting for covariates, males had 1.28 (1.06, 1.55) higher odds of statin prescription, in coronary heart disease patients only. In the overall study population, Black n on-Hispanics had 31% lower odds of statin prescription compared with White non-Hispanics, and patients seen only by a healthcare provider other than a physician were 80% less likely to have a statin prescribed to them. In conclusion, the disparity in statin prescription in patients with ASCVD exists across minority groups, and our findings underscore existing variations in healthcare delivery.
