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
The trial has finished. Results may not be published yet.
Stopped early This study
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 looked at whether giving antibiotics for 4 days instead of the usual 7 days is safe and effective for patients with ventilator-associated pneumonia (VAP). The goal was to reduce side effects from antibiotics while still treating the infection. The trial was stopped early after enrolling only 27 surgical patients, so the findings are limited.

What this could mean

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

Active substance
antibiotics
What this could lead to
If successful, this could show that a shorter course of antibiotics is safe and effective for early ventilator-associated pneumonia, reducing side effects and antibiotic resistance.
What could go wrong
The trial was terminated early with only 27 participants, so results are limited and may not be reliable. Shorter treatment might not clear the infection in all patients.

Inclusion Criteria: 1. Surgical patient 2. Early VAP, defined as VAP occurring within 2 - 7 days of intubation (via endotracheal or tracheostomy tube) (9). VAP will be defined according to local institutional protocol. 3. Hospital length of stay (LOS) \< 10 days at the time of VAP diagnosis. 4. Patients are willing to provide informed consent or their Legally Authorized Representative (LAR) is willing to provide informed consent on their behalf when the patient is unable (i.e., cognitively impaired from sedation on a ventilator) Exclusion Criteria: 1. Age \< 18 years 2. Prior episode of VAP for the index admission 3. VAP caused by any of the following pathogens: * Methicillin-resistant Staphylococcus aureus (MRSA) * Vancomycin-intermediate Staphylococcus aureus (VISA) * Pseudomonas aeruginosa * Vancomycin-resistant Enterococcus (VRE) * Acinetobacter baumanii * Stenotrophomonas maltophilia * Carbapenem-resistant Enterobacteriaceae (CRE) * Extended-spectrum beta lactamase-producing gram-negative bacilli 4. Causative pathogen not sensitive to choice of initial empiric antibiotic 5. Antibiotic therapy for \> 5 of the last 10 days preceding VAP diagnosis 6. Septic shock, defined as evidence of tissue hypoperfusion after adequate volume expansion, due to infection, and requiring \> 1 vasopressor (17) 7. Current or recent (within 30 days) use of immunosuppressive medications 8. LOS \> 72 hours at a transferring facility 9. Pregnancy or lactation 10. Legal arrest or incarceration 11. Moribund state in which death is imminent 12. ECMO (Extracorporeal membrane oxygenation) 13. Extubation prior to randomization
