N2 - Purpose: This study sought to investigate gender-based disparities in statin prescription rates and adherence among patients with peripheral arterial disease (PAD) and ischemic cerebrovascular disease (ICVD). Methods: We identified patients with PAD or ICVD seeking primary care between 2013 and 2014 in the VA healthcare system. We assessed any statin use, high-intensity statin (HIS) use, and statin adherence among women with PAD or ICVD compared with men. We also compared proportion of days covered (PDC) as a measure of statin adherence; PDC ≥ 0.8 deemed a patient statin adherent. Association between statin use (or adherence) and odds of death or myocardial infarction (MI) at 12-month follow-up was also ascertained. Results: Our analyses included 192,219 males and 3188 females with PAD and 331,352 males and 10,490 females with ICVD. Women with PAD had lower prescription rates of any statin (68.5% vs. 78.7%, OR 0.68, 95% confidence interval (CI) 0.62–0.75), HIS (21.1% vs. 23.7%, OR 0.88, 95% CI 0.79–0.97), and lower statin adherence (PDC ≥ 0.8: 34.6% vs. 45.5%, OR 0.75, 95% CI 0.69–0.82) compared with men. Similar disparities were seen in ICVD patients. Among female patients with PAD or ICVD, statin adherence was associated with lower odds of MI (OR 0.76, 95% CI 0.59–0.98), while use of any statin (OR 0.71, 95% CI 0.56–0.91) and HIS (OR 0.68, 95% CI 0.48–0.97) was associated with lower odds of death at 12 months. Conclusions: Women with PAD or ICVD had lower odds of receiving any statins, HIS, or being statin adherent. Targeted clinician- and patient-level interventions are needed to study and address these disparities among patients with PAD and ICVD.
