Postcards boost heart monitor reconnection by 30% in VA study
NCT ID NCT07464834
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether mailing informational postcards to patients with heart devices (like pacemakers or defibrillators) who had lost remote monitoring connection would help them reconnect. Over 2,700 patients from VA hospitals took part. The goal was to see if a simple reminder could improve how often patients stay linked to their care team.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients followed by the VA National Cardiac Device Surveillance Program for CIED remote monitoring care with a wireless-capable CIED (i.e., does not require manual transmission). * CIEDs: pacemakers, implantable cardioverter-defibrillators, and implantable loop recorders * Patients had a remote monitoring transmission received by VA National Cardiac Device Surveillance Program within past 100 days (representing standard 90-day interval plus additional 10-day buffer in case of travel) * Data from Abbott merlin.net, Biotronik Home Monitoring, Medtronic Carelink, or Boston Scientific Latitude indicating patient disconnected from remote monitoring for ≥16 days but ≤40 days Exclusion Criteria: * Address outside of United States or Puerto Rico * Previously included in the present RCT or a complementary RCT (VANCDSP Disconnected CIED). Once a patient reconnects but then becomes disconnected again, cannot be included again
