Summary

This single-center observational study aims to explore the relationship between the CPAx score (Chelsea Critical Care Physical Assessment Tool), measured at ICU discharge, and the 6-minute walk test (6MWT) distance performed 3 months after discharge. The study targets patients who experienced prolonged mechanical ventilation and were admitted to the ICU at CHI Elbeuf-Louviers-Val-de-Reuil. Eligible participants must show signs of malnutrition, muscular weakness, or post-traumatic stress symptoms. Data collection includes the CPAx score, 6MWT distance, MRC score, and relevant clinical and demographic information. The primary objective is to determine whether the CPAx score can predict long-term functional recovery and guide post-ICU rehabilitation strategies. Participants will be evaluated during routine follow-up in the day hospital. This non-interventional study poses minimal risk to participants.
