Temporal Trends in Cardiac Rehabilitation Participation and Its Core Components

Abstract

Purpose: Patient- and disease-specific data on cardiac rehabilitation (CR) participation and changes over time are limited. The objective of this study was to describe time trends in CR participation between 2013 and 2019 and provides insights into the utilization of CR components. Methods: Patients with cardiovascular disease (CVD) with an indication for CR were enrolled between 2013 and 2019. Dutch health insurance claims data were used to identify CR participation and its components. Results: In total, 106 212 patients with CVD were included of which 37% participated in CR. Participation significantly increased from 28% in 2013 to 41% in 2016 but remained unchanged thereafter. Participation was highest in the youngest age groups (<50 yrs 52%; 50-65 yrs 50%), men (48%), patients with ST-segment elevation myocardial infarction (73%), non–ST-segment elevation myocardial infarction (59%), and coronary artery bypass grafting (82%). In contrast, it was the lowest in the oldest age group (≥85 yrs 8%), women (30%), and in patients with heart failure (11%). Most participants in CR received referral plus an admission session (97%) and exercise training (82%), whereas complementary services related to dietary (14%) and mental health counseling (10%) had a low utilization. Conclusions: CR participation rates increased to 41% in 2016 but remained unchanged thereafter. Participation modulators included age, sex, CVD diagnosis, and undergoing a cardiothoracic procedure. Education and exercise sessions were frequently adopted, but dietary and mental health counseling had a low utilization rate. These findings suggest the need for reinvigorated referral and novel enrollment strategies in specific CVD subgroups to further promote CR participation and its associated underutilized adjunctive services.
