Feasibility and Safety of Medium-Term Remote-Only Monitoring in a Large Cohort of Biotronik Pacemaker Patients.

BACKGROUND: Remote monitoring (RM) enables convenient follow-up of patients with cardiac implantable electronic devices. In remote-only monitoring (RM-only), in-person visits are only scheduled if needed based on RM findings. This study evaluated the feasibility and safety of medium-term RM-only of pacemaker (PM) patients. METHODS: All patients with Biotronik PM were included in the analysis. Data on the number and causes of additional in-office device interrogations, actions due to the transmissions, hospitalizations and performance of RM were collected from a large cohort of PM patients followed by RM-only. RESULTS: In total, 606 patients (302 females) with a mean age of 78 ± 12 years were included in the analysis. During the mean follow-up of 2.8 years, 445 additional in-office device interrogations were made in 287 patients (0.3 interrogations/year), and in 110 (25%) of these cases, changes to device programming were made. In a subgroup analysis of 100 patients with at least one year of prior appointment-based device monitoring, the need for in-office visits was 6.9 times higher per follow-up year than in RM (IRR = 6.9, 95% CI 4.9-9.9; p < 0.001). The hospitalization rate in the entire cohort during RM was 0.3 / year with no difference in the rate of hospitalizations between the two monitoring methods (IRR 1, 95% CI 0.8-1.4, p = 0.8). The success of daily transmissions was 91.7%. CONCLUSION: Our real-world data indicate that RM-only may be a viable option for long-term follow-up of PM patients.
