Background: The November 2013 AHA/ACC prevention guidelines recommend the use of a fixed dose high potency statin (HPS) for patients with established atherosclerotic cardiovascular disease (ASCVD), irrespective of low-density lipoprotein cholesterol levels. We sought to determine how these guidelines are being adopted at the Veterans Affairs (VA) Health System and identify treatment gaps in patient groups. Methods: We examined administrative data from the VA 6 months prior to the index dates of 4/1/2013 and 4/1/2014 to identify patients with at least one outpatient visit for a diagnosis of established ASCVD, defined as coronary heart disease, cerebrovascular disease, or peripheral arterial disease. Statin use was assessed 6 months following the index date, and HPS was defined as atorvastatin 40mg or 80mg, rosuvasatin 20mg or 40mg, and simvastatin 80mg. Patient and facility-level predictors of statin use for secondary prevention were analyzed using multivariate logistic regressions. Results: Our study sample included 507,072 and 489,754 eligible adults with established ASCVD, in 4/1/2013 and 4/1/2014, respectively. The sample consisted of approximately 190,035 (2%) women and 200,461 (19%) non-white patients. HPS use was lowest in Hispanics and Native Americans, though all groups showed an increase over time (Figure 1). After adjustment for clinical and facility characteristics, there was a 40% increase in the use of HPS during the study period [OR=1.4; 95%CI (1.39-1.42)]. However, the racial differences shown in Figure 1 persisted and women were less likely to receive HPS than men (Odds Ratios [OR]=0.85; 95% CI 0.83-0.87). Conclusion: HPS use has increased following release of the ACC/AHA prevention guideline in the VA, though racial and gender disparities persist. Our findings highlight the continued need for targeted efforts to increase HPS use for women and certain minority groups.
