Purpose: The purpose of this study was to determine the difference in the rate of statin prescribing based on the Adult Treatment Panel (ATP) III and 2013 American College of Cardiology (ACC)/American Heart Association cholesterol guidelines across sex in Federally Qualified Health Centers (FQHCs), and to determine the proportion of patients on recommended statin dosage based on the 2013 cholesterol guideline. Methods: The Office Guidelines Applied to Practice (Office-GAP) study is a quasi-experimental, 2 FQHCs center study that enrolled patients with coronary heart disease and diabetes mellitus (DM). We computed 10-year atherosclerotic cardiovascular disease (ASCVD) risks scores based on ACC guidelines and determined the rate of statin prescribing across sex in FQHCs using both guidelines. Main outcomes measures were (1) rate of statin prescribing based on ATPIII and 2013 cholesterol guidelines across sex and (2) proportion of patients on recommended statin dosage based on the 2013 cholesterol guideline. Results: The 2013 cholesterol guideline did not increase the rate of eligibility of statin for men and women compared to ATPIII guideline. No significant difference between men and women in statin prescribing under ATPIII (67% vs 57%, P = .13) and 2013 cholesterol guidelines (66% vs 63%, P = .69) and in the recommended dosage of statin per the 2013 cholesterol guidelines between men and women in FQHCs (12% vs 22%, P = .22). Conclusions: We found statin underprescribing for both men and women with ASCVD and DM in FQHCs. Utilizing both the ATPIII and the 2013 cholesterol guidelines, men with ASCVD and DM were prescribed statin more than women. However, fewer men were found to be on the recommended dosage of statin based on the 2013 cholesterol guideline. Our findings suggest that Office-GAP may have improved the prescription/use of statin in both men and women.
