French Cohort of COVID-19 Patients With Post-intensive Care Syndrome (COREADOM)

September 5, 2025 updated by: Assistance Publique - Hôpitaux de Paris

French Cohort of covid19 Patients With Post-intensive Care Syndrome : Rehabilitation From Intensive Care Unit to Home Return - Spatio-temporal Analysis of Walking Compared to Asymptomatic Participants

The purpose of this study is to describe post-intensive care syndrome (PICS) of patients surviving to coronavirus disease 2019 (COVID19) and their rehabilitation and recovery process from hospital to home return

Study Overview

Detailed Description

The novel coronavirus, Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing the COVID-19 emerged in December 2019 and was declared pandemic in March 2020.

Although the majority of reported COVID-19 cases are mild, approximatively 5% of patients require a stay in intensive care unit, with mechanical ventilation.

Post intensive care syndrome (PICS) consists of physical, cognitive and psychological dysfunctions.

Little is known about the rate and clinical presentations of PCIS among patients surviving to COVID-19.

The objective of this study is to describe the clinical manifestations of PCIS in COVID-19 patients, and their rehabilitation process until home return.
