Background: Studies have shown that women with acute myocardial infarction (AMI) are less likely to receive evidence-based care compared with men. The American College of Cardiology's AMI Guidelines Applied in Practice (GAP) program has been shown to increase the rates of evidence-based medicine use and reduce mortality in patients with AMI. The objective of this study was to investigate the relative benefits of the GAP program in men and women.
Methods: By using a predesign-postdesign, standard orders, and a discharge tool to improve evidence-based indicator rates and long-term mortality in patients with AMI in Michigan, this study compared the success of GAP in men vs women. Logistic regression was used to develop predictive models for death at 30 days and 1 year in men and women.
Results: Use of evidence-based care, including use of beta-blockers and aspirin in men and women at hospital discharge and lipid-lowering agent use in men, was higher in the post-GAP sample (P<.01 for all). Use of the discharge tool promoted by the GAP program was independently protective against death at 1 year in women (adjusted odds ratio, 0.46; 95% confidence interval, 0.27-0.79), and a trend existed for similar results in men (adjusted odds ratio, 0.62; 95% confidence interval, 0.36-1.06). However, the tool was used slightly less often with women (27.9% vs 33.96%; P=.003).
Conclusions: The GAP program increased the use of evidence-based therapies in male and female patients. In addition, the GAP discharge tool may decrease mortality rates at 1 year in patients with AMI; however, the tool was used less often with women. Greater use of the GAP discharge tool in women might narrow the post-MI sex mortality gap.
