Development and Evaluation of the Readiness for EXtubation Score REXs to Predict Extubation Success in Adults Using Mechanical Ventilation in ICU

What this Trial Is About

Researchers are evaluating a new multi-component score called the Readiness for EXtubation score REXs to predict when ICU patients on invasive mechanical ventilation are ready to be extubated. The process of liberation from mechanical ventilation involves weaning, readiness assessment, and extubation, with success defined as not needing invasive support within 48 hours. This study focuses on developing and analyzing REXs to help clinicians assess extubation readiness more accurately in critically ill patients. The study involves daily screening of ICU patients undergoing weaning from invasive mechanical ventilation. Data collected include clinical parameters such as arterial blood gases, ventilation settings, sedation and agitation scores, heart rate, hemoglobin levels, nutritional status, and cough strength, among others. Clinicians will anonymously enter data into an electronic case report form to develop and evaluate the REXs score. Patients prepared for extubation will have their readiness assessed using this score. Participants will be monitored during their ICU stay, with data collected on extubation success or failure at 24, 48, and 72 hours after extubation. Researchers will also track length of ICU and hospital stays and mortality outcomes. The study uses routine clinical data, with anonymization to protect patient confidentiality. Statistical methods will analyze associations between clinical factors and extubation outcomes to validate the REXs scores predictive ability. The total study duration extends until the end of 2026.
