The cost-effectiveness of a digitally enabled telerehabilitation program delivered nationally to patients in Australia

Abstract

Abstract Introduction Traditionally delivered cardiac rehabilitation (CR) programs have considerable benefits, yet access and participation remains low. Emerging digital health models offer promise in healthcare delivery, but their benefits and impact on healthcare utilization and cost-effectiveness are uncertain. We conducted a cost-effectiveness analysis of a telehealth program with a CR mobile app for post-hospitalization coronary heart disease (CHD) patients. Purpose To assess whether a digitally enabled CR program is cost-effective compared with a propensity matched usual care control group in the Australian health system. Methods Patients were recruited nationally, through a health insurer, following hospitalization for CHD. Participants received weekly telehealth consultations for up to 8 weeks, supplemented by use of an mHealth app. Using administrative private health insurance claims data, we assessed differences in hospital costs, mortality rates and bed days at 12-months post discharge. Incremental cost effectiveness ratios (ICERS) were calculated to determine the cost per deaths prevented and cost per bed days saved for the digital-CR group (n=133) compared with usual care (n=266). Results Among the cohort, 36% lived in regional/rural areas, 70% were male and the mean age was 68 years. The mean total hospital all cause readmission costs at 12-months were $1,488 AUD less in the digital-CR group ($16,411) compared to the usual care group ($17,899). Digital-CR had fewer total hospital days relative to the usual care group (median of 2 vs 3 days) and patients in the digital-CR group had a significantly lower mortality rate at 12-months post discharge. The ICERs were -$337 per 100 patient deaths prevented and -$3,033 per median bed days saved. Conclusion The implementation of a digital-CR program demonstrates cost-effectiveness for patients with CHD when compared to usual care. Thus, advocating for the widespread availability of digital-CR programs as an option for CHD patients following hospital discharge is warranted.
