What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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

Summary

This study tests whether a mobile health program, including self-measured blood pressure monitoring and help scheduling doctor visits, can lower blood pressure better than usual care. It enrolls adults who have very high blood pressure during a safety-net emergency department visit. The goal is to see if this approach can reduce future heart attacks, strokes, and dementia.

What this could mean

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

Active substance
mobile health intervention with self-measured blood pressure monitoring and appointment scheduling
What this could lead to
If successful, this approach could offer a scalable way to control high blood pressure in underserved populations, potentially reducing heart attacks, strokes, and dementia.
What could go wrong
This is a relatively early-stage trial with 500 participants, and the intervention relies on patient engagement and technology access, which may limit real-world effectiveness.
