Speedy bug ID: new tests aim to cut antibiotic guesswork in ICU blood infections

NCT ID NCT05741424

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 Results may not be published yet.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.

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This status has not been confirmed recently, so it may be out of date.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 study tested whether three new diagnostic tools could help doctors pick the best antibiotic faster for ICU patients with Gram-negative bloodstream infections. Researchers compared standard lab methods to the new tests in 100 patients. The goal was to see if more patients got the right, narrowest antibiotic within 24 hours of a blood sample.

What this could mean

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

Active substance
Diagnostic tests (BacT/Alert VIRTUO, BioFire BCID2, REVEAL)
What this could lead to
If successful, this could show that using these advanced tests helps doctors pick the most effective antibiotic sooner, potentially improving patient outcomes in the ICU.
What could go wrong
This is a small, single-center study with only 100 patients, so results may not apply to all hospitals. The tests themselves don't treat the infection—they only guide treatment decisions.

Other sponsor

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

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
