PURPOSE: The six-month prescription-filling rates for key secondary-prevention drugs in Department of Veterans Affairs (VA) patients who had undergone coronary artery bypass grafting (CABG) were studied. METHODS: Patient records for elective CABG from April 2000 through March 2002 (divided into four six-month periods) were analyzed. The study population included 8925 CABG-only patients surviving to hospital discharge. For each six-month period and in aggregate, the primary study endpoint was the six-month prescription-filling rate. RESULTS: Across the four six-month periods, prescription-filling rates increased for all categories of medications studied. There were modest progressive increases for lipid-lowering agents, statins, -blockers, angiotensin-converting-enzyme Inhibitors, and angiotensin-receptor blockers. The antithrombotic-filling rate averaged 88.5%. Filling rates for aspirin were much higher than for aspirin alternatives. CONCLUSION: Prescription-filling rates for post-CABG medications in VA facilities were generally high and suggested compliance with guidelines for the prevention of cardiovascular events.
