Purpose: Atherosclerotic cardiovascular disease (ASCVD) is a leading cause of mortality worldwide. Statins, which are effective in preventing ASCVD, are underused, particularly for primary prevention. This study examined trends in statin use for primary ASCVD prevention from 1999 to 2020, focusing on demographic variations. Methods: Utilizing data from the National Health and Nutrition Examination Survey, the present study includes individuals aged 18 years and older who had a greater than 10% risk of ASCVD over 10 years, and excluded patients with existing ASCVD. Subgroup analyses by demographic categories were performed. We calculated the changes in statin usage and used linear and quadratic tests to assess the linear and nonlinear trends in those changes. Results: A total of 10,037 participants were included. Statin usage increased from 16.16% in 1999 to 36.24% in 2010, and 41.74% in 2020 (quadratic P-value < 0.001). In the 18–44 years age group, statin usage increased from 2.52% in 1999 to 8.14% in 2020 (linear P-value = 0.322), showing no significant linear trend. In the "never-married" group, statin usage increased from 19.16% in 1999 to 30.05% in 2020 (linear P-value = 0.256). Conclusion: Statin usage has shown a positive trend among populations requiring primary prevention for ASCVD. Currently, health policies are proving effective. However, the overall statin usage rate remains less than 50%. Additionally, young and never-married individuals should also receive special attention regarding statin usage as primary treatment for ASCVD. [ABSTRACT FROM AUTHOR]

Importance Drug coupons are widely used, but their effects are not well understood. Objective To quantify the effect of coupons on statin use and expenditures. Design Retrospective cohort analysis of IMS Health LRx LifeLink database. Setting U.S. retail pharmacy transactions. Participants Incident statin users who initiated branded atorvastatin or rosuvastatin between June 2006 and February 2013. Main Outcomes and Measures Monthly statin utilization (pill-days of therapy), switching (filling a different statin), termination (failure to refill statin for 6 mo), and out-of-pocket and total costs. Results Of 1.1 million incident atorvastatin and rosuvastatin users, 2% used a coupon for at least one statin fill. At 1 year, compared with noncoupon users, those who used a statin coupon on their first fill were dispensed an equal number of monthly pill-days (23.7 vs 23.8), were less likely to switch statins (14.4% vs 16.3%), and were less likely to have terminated statin therapy (31.3% vs 39.2%). At 4 years, coupon users were more likely to have switched (45.5% vs 40.8%) and less likely to have terminated statin therapy (50.6% vs 61.1%) compared with noncoupon users. Those who used greater numbers of coupons were substantially less likely to switch and terminate statin therapies. Monthly out-of-pocket costs were lower among coupon than noncoupon users at 1 year ($9.7 vs $15.1), but total monthly costs were qualitatively similar ($115.5 vs $116.9). At 4 years, monthly out-of-pocket costs among coupon users remained lower ($14.3 vs $16.6) compared with noncoupon users. Sensitivity analyses supported the main results. Conclusions Coupons for branded statins are associated with higher utilization and lower rates of discontinuation and short-term switching to other statin products. [ABSTRACT FROM AUTHOR]
