Use of Health Care System-Supplied Aspirin by Veterans With Postoperative Heart Attack or Unstable Angina
Abstract
Evidence-based guidelines for the use of aspirin in secondary prevention of cardiovascular disease events are well established. Despite this, the prevalence of aspirin use for secondary prevention is suboptimal. The study aimed to determine the prevalence of aspirin use for secondary prevention of cardiovascular disease events when it is dispensed as a prescription, as is performed in the Veterans Affairs (VA) managed care system. VA patients who had undergone major surgery and experienced a postoperative myocardial infarction (MI) or unstable angina between the years 2005 and 2009 were identified from administrative databases. VA pharmacy records were used to determine whether a prescription for aspirin was filled after the postoperative MI or unstable angina. Multivariable logistic regression models estimated odd ratios of filling aspirin prescriptions for the predictors of interest. Of the 321,131 men and women veterans who underwent major surgery, 7,700 experienced a postoperative MI or unstable angina. Among those 7,700, 47% filled an aspirin prescription. Only 59% of veterans with no co-pay filled an aspirin prescription. Aspirin fills were more common in younger veterans, Blacks, Hispanics, males, hypertensive veterans, ...Continue Reading
