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.

Completed
The trial has finished. Results may not be published yet.
Stopped early

Summary

This study looks at whether changing the filter in a kidney dialysis machine more often than usual can lower the chance of new infections in critically ill patients with severe acute kidney injury. About 100 adults in intensive care will be randomly assigned to have their filter changed every 36 hours or every 48-72 hours. The goal is to see if the shorter filter lifespan is practical and helps reduce infections.

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.

Expected to start

Jun 2026

An estimate. Start dates often move.

Expected to finish

Jun 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
