title: Predictors for not completing exercise-based rehabilitation following cardiac surgery.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  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.
