Low Medication Persistence for Older STEMI Patients
(HealthDay News) — For older patients with non-ST-segment elevation myocardial infarction, evidence-based medication (EBM) persistence is similar after discharge from academic and nonacademic hospitals, according to a study published in the November 15 issue of The American Journal of Cardiology.
Jennifer Rymer, MD, MBA, from the Duke University Medical Center in Durham, NC, and colleagues examined whether there is a difference in medication persistence between patients discharged from academic vs. nonacademic hospitals. Medicare pharmacy claims data were obtained for 3,184 patients with non-ST segment elevation myocardial infarction, aged >65 years, who were treated at 253 hospitals in 2006.
The researchers found that, at discharge, composite persistence to all EBMs was low and did not differ significantly between those discharged from academic vs. nonacademic hospitals at 90 days (46 vs. 45%; adjusted incidence rate ratio, 0.99; 95% confidence interval, 0.95–1.04) or at one year (39 vs. 39%; adjusted incidence rate ratio, 1.02; 95% confidence interval, 0.98–1.07).
"Rates of persistence to EBMs were similar between patients with myocardial infarction >65 years old treated at academic vs. nonacademic hospitals; however, persistence rates are low both early and late postdischarge, highlighting a continued need for quality improvement efforts to optimize post-myocardial infarction management," the authors write.
