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 This study
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 Results may not be published yet.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

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 tests whether an AI-powered app can improve follow-up for patients recovering from surgery with a continuous nerve block for pain. 166 adults will use either the AI app or a standard automated messaging system. The goal is to see if the AI reduces the number of times patients need to contact their doctor, while keeping satisfaction high.

What this could mean

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

Active substance
AI-driven follow-up platform
What this could lead to
If successful, this could provide a more efficient and personalized way to monitor patients after surgery, reducing unnecessary calls to doctors while keeping patients safe and satisfied.
What could go wrong
This is a small, early-stage study (166 participants) comparing two digital tools, not a new treatment. The AI may not reduce re-consultations as hoped, and results may not apply to all surgical patients.

This is an AI summary of the original study and may miss details. Read our disclaimer.
