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 This study
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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 trial is testing whether an AI system can measure the area of pressure ulcers (bedsores) as accurately as the traditional manual grid-counting method, but in less time. Adults with pressure ulcers will have a transparent grid film placed on their wound, and a single photo will be taken. The same image will then be measured both by the AI and by trained staff, and the results and time taken will be compared. The goal is to see if AI can offer a reliable, faster way to track wound healing.

What this could mean

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

Active substance
AI grid image recognition measurement using a sterile transparent grid film
What this could lead to
If successful, this could provide a faster, more consistent way to measure wound size in clinical practice, improving pressure ulcer care and monitoring.
What could go wrong
The trial is small and early, and AI accuracy may vary across different wound types or skin tones. It also depends on image quality and may not replace manual methods in all settings.

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

About 100 people

The number the study aims to enrol. It can still change while the study runs.

Started

Jul 2026

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor
