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 Results may not be published yet.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.

Summary

This study tested whether special UV light devices placed in common areas of nursing homes can reduce the number of severe respiratory infections (like pneumonia or COVID-19) in elderly residents. Over 1,600 residents in 12 French nursing homes took part. The devices were either active or deactivated (as a placebo) to see if they made a difference. Results are expected by mid-2026.

What this could mean

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

Active substance
Upper-room UVGI (Ultra-Violet Germicidal Irradiation) device
What this could lead to
If it works, this could provide a simple, non-drug way to prevent serious respiratory infections in nursing homes, potentially saving lives and reducing hospitalizations.
What could go wrong
This is a completed trial, but results are not yet published. The devices may not significantly reduce infections, and effectiveness could vary by setting or compliance.
