Objectives

To enhance adherence to cardiac rehabilitation (CR), a patient education programme called ‘learning and coping’ (LC-programme) was implemented in three hospitals in Denmark. The aim of this study was to investigate the cost–utility of the LC-programme compared with the standard CR-programme. 

Methods

825 patients with ischaemic heart disease or heart failure were randomised to the LC-programme or the standard CR-programme and were followed for 3 years.  A societal cost perspective was applied and quality-adjusted life years (QALY) were based on SF-6D measurements. Multiple imputation technique was used to handle missing data on the SF-6D. The statistical analyses were based on means and bootstrapped SEs. Regression framework was employed to estimate the net benefit and to illustrate cost-effectiveness acceptability curves. 

Results

No statistically significant differences were found between the two programmes in total societal costs (4353 Euros; 95% CI –3828 to 12 533) or in QALY (–0.006; 95% CI –0.053 to 0.042). At a threshold of 40 000 Euros, the LC-programme was found to be cost-effective at 15% probability; however, for patients with heart failure, due to increased cost savings, the probability of cost-effectiveness increased to 91%. 

Conclusions

While the LC-programme did not appear to be cost-effective in CR, important heterogeneity was noted for subgroups of patients. The LC-programme was demonstrated to increase adherence to the rehabilitation programme and to be cost-effective among patients with heart failure. However, further research is needed to study the dynamic value of heterogeneity due to the small sample size in this subgroup.
