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 Results may not be published yet.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.

Summary

This study is testing whether a wearable device can give early warning of complications after chest surgery. The device tracks heart rate, oxygen levels, temperature, and activity from hospital admission to 30 days after discharge. Researchers will first use past data to build a warning model, then test it in 650 new patients to see how early and accurately it predicts problems like infection or irregular heartbeat.

What this could mean

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

Active substance
wearable device (monitors heart rate, oxygen, temperature, activity, sleep)
What this could lead to
If successful, this could lead to a way to catch serious complications like lung infections or heart rhythm problems days earlier than usual, helping doctors intervene sooner.
What could go wrong
This is an early-stage study to develop and test a model, not a proven tool. The device only monitors and does not change care, so it may not actually improve outcomes.
