Readiness for EXtubation (REXs) score for patients on invasive mechanical ventilation

A New Tool for Extubation Readiness in Mechanically Ventilated Patients: Readiness for EXtubation Score (REXs STUDY)

Observational Medipol University · NCT07098611

This will test the Readiness for EXtubation (REXs) score to see if it can predict which ICU patients on invasive mechanical ventilation can be safely extubated.

What this trial studies

This observational, multi-center study aims to develop and validate a multi-component Readiness for EXtubation (REXs) score using clinical parameters and spontaneous breathing trial results in patients undergoing weaning from invasive mechanical ventilation. The score will be derived and calibrated across participating ICUs, with extubation success defined as not requiring invasive mechanical support within 48 hours. Standard inclusion and exclusion criteria will be applied and sites will report findings following the STROBE guidance. Collected data will be used to test predictive performance and optimize score thresholds before broader validation.

Who should consider this trial

Good fit: ICU patients who are in the weaning process from invasive mechanical ventilation and meet readiness-for-extubation clinical criteria, excluding tracheostomized or pregnant patients, are ideal candidates.

Not a fit: Patients who are tracheostomized, pregnant, have diaphragmatic pacers, lack legal guardian consent, or are enrolled in other studies are not eligible and unlikely to benefit from this score.

Why it matters

Potential benefit: If successful, the REXs score could help clinicians reduce failed extubations and avoid unnecessary prolonged ventilation.

How similar studies have performed: Other multi-component weaning and extubation prediction scores and SBT-based approaches have been used with mixed success, so REXs builds on prior work but is not yet definitive.
