Abstract:

BACKGROUND: Intensive statins are superior to moderate statins in reducing morbidity and mortality after an acute myocardial infarction. Although studies have documented rates of statin prescription as a quality performance measure, variations in hospitals'' rates of initiating, intensifying, and maximizing statin therapy after acute myocardial infarction are unknown. METHODS AND RESULTS: We assessed statin use at admission and discharge among 4340 acute myocardial infarction patients from 24 US hospitals (2005-2008). Hierarchical models estimated site variation in statin initiation in naïve patients, intensification in those undergoing submaximal therapy, and discharge on maximal therapy (defined as a statin with expected low-density lipoprotein cholesterol lowering = 50%) after adjustment for patient factors, including low-density lipoprotein cholesterol level. Site variation was explored with a median rate ratio, which estimates the relative difference in risk ratios of 2 hypothetically identical patients at 2 different hospitals. Among statin-naïve patients, 87% without a contraindication were prescribed a statin, with no variability across sites (median rate ratio, 1.02). Among patients who arrived on submaximal statins, 26% had their statin therapy intensified, with modest site variability (median rate ratio, 1.47). Among all patients without a contraindication, 23% were discharged on maximal statin therapy, with substantial hospital variability (median rate ratio, 2.79). CONCLUSIONS: In a large, multicenter acute myocardial infarction cohort, statin therapy was begun in nearly 90% of patients during hospitalization, with no variability across sites; however, rates of statin intensification and maximization were low and varied substantially across hospitals. Given that more intense statin therapy is associated with better outcomes, changing the existing performance measures to include the intensity of statin therapy may improve care.
