Abstract P310: Predictors of Phase III Enrollment in Participants Completing Phase II Cardiac Rehabilitation in a Large Urban Cardiac Rehabilitation Center
Background: Short duration of outpatient Phase II cardiac rehabilitation (CR) program is not sufficient to sustain benefits of CR. Participation in long-term Phase III CR improves exercise capacity and lipoprotein profile.
Hypothesis: We examined the factors predicting Phase III CR enrollment in those who have successfully completed Phase II CR in a large urban CR center.
Methods: 4714 participants who completed structured 36-session Phase II CR program from the year 2000 to 2014 were included in this retrospective study. Multivariable logistic regression model was used to identify demographic, socio-economic factors predicting Phase III CR enrollment. The Cochran-Armitage test was used to assess temporal trends in Phase III CR enrollment.
Results: A total of 901, out of 4714 participants completing Phase II CR, enrolled into Phase III CR. Mean age was 65 years and 31% were females. Univariate predictors include age, race, education, occupation, income, return to work obligation, insurance status, weight loss, depression and anxiety, exercise duration, and metabolic equivalents (METs). On multivariable logistic regression, those with at least college education (Odds Ratio [OR] 1.5,95% confidence interval [CI], 1.07-2), depression (OR,1.5, 95% CI, 1.07-1.96), weight loss (OR, 1.03, 95% CI, 1.01-1.05) and attending more Phase II sessions (OR,1.06, 95% CI, 1.02-1.10) were more likely to enroll whereas those living > 30 minutes from CR center (OR, 0.40, 95% CI, 0.20-0.75), with higher METs (OR,0.93, 95% CI, 0.87-0.99) and exercising longer (OR, 0.96, 95% CI, 0.93-0.99) were less likely to enroll. There is significantly increased temporal trend for Phase III CR enrollment (Z=11.34, P<0.0001).
Conclusion: In participants completing Phase II CR, higher education, depression and weight loss predict increased Phase III CR enrollment whereas increased distance from CR center or better exercise capacity predict decreased Phase III CR enrollment.
