Key result
Readmission within 8 weeks (OR 2.50), antidepressant use (OR 2.40), overweight (OR 1.81), and being single (OR 1.12) were significantly associated with not completing cardiac rehabilitation.

What factors are associated with patients not completing exercise-based cardiac rehabilitation following cardiac surgery?
Readmissions, antidepressant use, obesity, and being single are significant predictors of non-completion of exercise-based cardiac rehabilitation after cardiac surgery, highlighting populations that may need targeted adherence interventions.
May flag high-risk patients for adherence support post-surgery; hypothesis-generating in observational data and needs prospective validation.
OBJECTIVES: The beneficial effects of exercise-based cardiac rehabilitation (ECR) are well documented. A substantial proportion of patients fail to complete ECR. The purpose of this study was to identify factors associated with patients not completing ECR. DESIGN: Registry based and data from medical records. The study population was surgically treated heart patients with ischaemic and/or heart valve diseases referred to ECR between August 2008 and January 2011 at Aarhus University Hospital, Denmark. The ECR was an 8-week course with 1-h biweekly sessions. Patients were non-completers when attending ≤ 75% of sessions. Data were analysed in a multivariate logistic regression model. RESULTS: Of 364 patients, 73% were referred to ECR, 42% did not complete the ECR and 28% never showed up. Readmission within 8 weeks post-discharged odds ratio (OR) of 2.50 (95% confidence interval [CI], 1.40-4.46), prescribed antidepressant medication OR of 2.40 (95% CI, 1.21-4.74), overweight OR of 1.81 (95% CI, 1.03-3.18), or being single OR of 1.12 (95% CI, 1.07-1.70) was significantly associated with not completing ECR. CONCLUSION: We identified a high rate of patients not completing ECR. Readmissions, antidepressant medication, marital status and obesity should warrant clinical attention when designing future interventions to improve adherence to ECR.

Laustsen et al. (2013) conducted a cohort in Ischaemic and/or heart valve diseases (n=364). Risk factors (readmission, antidepressant use, overweight, being single) vs. Absence of risk factors was evaluated on Not completing exercise-based cardiac rehabilitation (attending ≤ 75% of sessions) (OR 2.50, 95% CI 1.40-4.46). Readmission within 8 weeks (OR 2.50), antidepressant use (OR 2.40), overweight (OR 1.81), and being single (OR 1.12) were significantly associated with not completing cardiac rehabilitation.
