Understanding recovery after acute respiratory distress syndrome

Longitudinal Recovery Trajectories After an Acute Respiratory Distress Syndrome, a New Understanding. The TENACITY Study

Observational Institut de Recerca Biomèdica de Lleida · NCT06083363

This study looks at how well people recover after surviving acute respiratory distress syndrome, especially those affected by COVID-19, to see how their lung function, symptoms, and overall quality of life change over a year.

What this trial studies

This observational study aims to explore the long-term recovery trajectories of patients who have survived acute respiratory distress syndrome (ARDS), particularly focusing on those affected by COVID-19 compared to other causes. It will assess various dimensions of recovery, including lung function, symptoms, quality of life, neurocognitive status, exercise capacity, and molecular profiles. The study seeks to identify risk factors for pulmonary sequelae and understand the underlying mechanisms of severe lung injury over a one-year follow-up period after hospital discharge.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have been admitted to the ICU with a diagnosis of severe pneumonia or ARDS.

Not a fit: Patients with a life expectancy of less than a year or those unable to participate in pulmonary function tests due to severe mental disabilities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of long-term respiratory complications in ARDS survivors.

How similar studies have performed: While there have been studies on ARDS recovery, this specific comparison between COVID-19 and non-COVID-19 ARDS recovery trajectories is novel and has not been extensively tested.
