What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether mailing a simple postcard to patients with heart devices (like pacemakers or defibrillators) that had lost remote monitoring connection could help them reconnect. Over 1,300 VA patients received either a tailored postcard with tips or no postcard. The goal was to see if the postcard reduced the time to reconnection and improved adherence to scheduled transmissions.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
tailored postcards
What this could lead to
If it works, this simple approach could help more patients stay connected to their heart device monitoring, potentially preventing complications.
What could go wrong
This is a completed trial testing a low-cost intervention, so the main risk is that postcards may not significantly improve reconnection rates.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

1,312 people

The number who actually took part.

Started

Aug 2024

Finished

Lead sponsor

A government agency

The lead sponsor is a US federal agency other than the NIH.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

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 Monitor). Once a patient reconnects but then becomes disconnected again, cannot be included again
