The impact of remote monitoring of implanted cardioverter-defibrillator (ICD) and cardiac resynchronisation therapy device (CRT-D) patients on healthcare costs in the Silesian population: three-year follow-up

Background: The population of patients with implanted cardioverter-defibrillators (ICD) and cardiac resynchronisation therapy devices (CRT-D) is constantly growing. The use of remote-monitoring (RM) techniques in this group can significantly improve clinical outcomes, but there are limited data about the impact of RM on healthcare costs from a payer's perspective. Aim: The aim of the study was to assess the impact on costs for the healthcare system of RM in patients with ICD or CRT-D. Methods: We examined a cohort of 842 patients with ICD or CRT-D. The group was divided into two groups based on RM (or no RM [NRM]), matched according to important clinical characteristics. The subjects were followed for a maximum of three years after implantation (mean follow-up 2.11 +/- 0.83 years). The overall costs for the healthcare provider in the follow-up were defined as the primary endpoint. The secondary endpoint was the use of different types of medical contact events: hospitalisation and number of in-clinic and general practitioner visits (without the number of remote transmissions). Results: In the three-year follow-up, the reduction in the costs of treatment for National Health Care in the RM group was 33.5% (median value, p < 0.001). In patients with implanted CRT-D, the reduction reached 42.7% (p = 0.011), and with ICD it was 31.3% (p = 0.007). We observed no significant reduction in the median hospitalisation costs in the three-year follow-up in the RM group (p = NS), despite a 25% drop in the mean value. The costs of outpatient visits were slightly higher in the RM group (p = NS). In the follow-up period, there was no reduction in the number of medical contact events (p = NS). Conclusions: Remote monitoring in patients with implanted ICD or CRT-D devices reduces the cost for the national healthcare provider.
