Referral to and enrolment in cardiac rehabilitation after open-heart surgery in the Netherlands

Aim: Although referral to phase 2 cardiac rehabilitation (CR) following open-heart surgery is recommended in professional guidelines, according to the literature, participation rates are suboptimal. This study investigates the referral and enrolment rates, as well as determinants for these rates, for phase 2 CR following open-heart surgery via sternotomy. Methods: A cross-sectional survey study was conducted among patients who underwent open-heart surgery via sternotomy in a university hospital. Data on referral and enrolment rates and possible factors associated with these rates (age, sex, type of surgery, educational level, living status, employment, income, ethnicity) were collected by a questionnaire or from the patient’s medical file. Univariate logistic regression analysis (odds ratio) was used to study associations of patient characteristics with referral and enrolment rates. Results: Of the 717 eligible patients, 364 (51%) completed the questionnaire. Their median age was 68 years (interquartile range 61–74) and 82 (23%) were female. Rates for referral to and enrolment in phase 2 CR were 307 (84%) and 315 (87%), respectively. Female sex and older age were independently associated with both non-referral and non-enrolment. Additional factors for non-enrolment were surgery type (coronary artery bypass grafting with valve surgery and miscellaneous types of relatively rare surgery), living alone and below-average income. Conclusion: Phase 2 CR referral and enrolment rates for patients following open-heart surgery were well over 80%, suggesting adequate adherence to professional guidelines. During consultation, physicians and specialised nurses should pay more attention to certain patient groups (at risk of non-enrolment females and elderly). In addition, in-depth qualitative research to identify reasons for non-referral and/or non-enrolment is needed.
