title: Effect of an American Heart Association Get With the Guidelines program-based clinical pathway on referral and enrollment into cardiac rehabilitation after acute myocardial infarction.
abstract: Cardiac rehabilitation (CR)/secondary prevention programs are an important part of patient care after acute myocardial infarction (AMI). However, only 10% to 15% of eligible patients enroll in such programs. The purpose of this study was to evaluate the effect of an American Heart Association Get With the Guidelines (GWTG)-based clinical pathway on referral and enrollment into CR after AMI. Patients (n = 780) admitted to a single center during an 18-month period with AMI and discharged to home were evaluated retrospectively for referral and enrollment into CR programs. A total of 714 patients (92%) were on the GWTG pathway; 392 (55%) were referred and 135 (19%) were enrolled into CR. Higher referral was associated with pathway use (odds ratio [OR] 2.3, 95% confidence interval [CI] 1.1 to 4.9, p = 0.03), percutaneous coronary intervention (OR 3.1, 95% CI 1.9 to 5.2, p <0.0001), and in-patient physical therapy consultation (OR 13, 95% CI 8.2 to 20.5, p <0.0001). Ethnicity did not affect referral, but was the only variable associated with lower enrollment. Hispanic and black patients had 92% (OR 0.08, 95% CI 0.01 to 0.55, p = 0.02) and 57% (OR 0.43, 95% CI 0.19 to 1.05, p = 0.06) lower odds to enroll compared with white patients, respectively. In conclusion, use of the American Heart Association GWTG pathway showed a significantly higher referral rate to CR after AMI than previously reported in the literature. Nonetheless, most referred patients did not enroll. Strategies to bridge the gap between referral and enrollment in CR should be incorporated into AMI clinical pathways, with special emphasis on increasing enrollment in ethnic minorities.
