Observing recovery from weakness after severe respiratory and cardiac failure
Official title: Prospective Observational Study Regarding the Determinants of Functional Disability and Quality of Life in Patients Recovering From Severe Acute Cardiac or Respiratory Failure Considered for Mechanical Cardiorespiratory Support (CLEVERER)
Run by Barts & The London NHS Trust · NCT03753412 · Data updated 2026-11-12
This study looks at how people who had severe breathing and heart problems recover from weakness after being in intensive care and on a special life-support machine, to see what helps or hinders their recovery.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults over 18 years old who have experienced severe cardiorespiratory failure requiring ECMO.
✕Probably not a fit
Patients with previous strokes, neuromuscular diseases, malignancies, or those under 18 years old may not benefit from this study.

What this trial studies
This observational pilot study aims to identify the factors influencing recovery from intensive care unit-acquired weakness (ICUAW) in patients who have experienced severe cardiorespiratory failure and required extra-corporeal membrane oxygenation (ECMO). The study will assess the impact of ICUAW on physical function and health-related quality of life (HRQoL) following critical illness. By examining real-life cases, the research seeks to uncover the determinants of recovery and the associated risks of ICUAW, which can significantly affect patient outcomes.
Why it matters
Potential benefit: If successful, this study could lead to improved recovery strategies for patients suffering from ICUAW, enhancing their physical function and quality of life.
How similar studies have gone: While the phenomenon of ICUAW has been recognized, this study aims to explore its determinants in a specific patient population, making it a novel approach in this context.
