Bittner V, et al. - Researchers investigated factors that drive variation in high-intensity statin use after acute myocardial infarction among older adults. For this retrospective cohort analysis, they used Medicare administrative claims and enrollment data to identify a cohort of 139 643 Medicare fee-for-service beneficiaries hospitalized for myocardial infarction. The analysis revealed an increase in post-discharge high-intensity statin use from 23.4% in 2011 to 55.6% in 2015. Multivariable-adjusted models suggested a more strong correlation of geographic region with high-intensity statin use after myocardial infarction than hospital or patient characteristics.
