Early Rehabilitation in Patients on Extracorporeal Membrane Oxygenation (ECMO-Rehab)

A Randomised Controlled Trial of Early Rehabilitation in Patients on Extracorporeal Membrane Oxygenation (ECMO-Rehab)

Critically ill patients who require extracorporeal membrane oxygenation (ECMO) are the sickest in the hospital. More patients are surviving but survivors have compromised functional recovery for months or years. This registry-embedded randomised trial aims to determine if early rehabilitation commenced within 72 hours of ECMO is feasible and improves muscle strength and functional status in patients compared to standard practice in a randomised controlled trial of 100 ICU patients. The effect of the intervention on mortality, health status, and function at 180 days will be evaluated, as well as cost-effectiveness. ECMO-Rehab trial is a registry embedded trial and will be utilising EXCEL data.

Study Overview

• Status: Recruiting
• Conditions: Extracorporeal Membrane Oxygenation Complication
• Intervention / Treatment: Other: Early Rehabilitation

Detailed Description

The trial is a 100-patient, multicentre, randomised, controlled, parallel-group, two-sided superiority trial that will randomly allocate eligible patients to early rehabilitation or standard care in a 1:1 ratio to determine if early rehabilitation of critically ill patients receiving ECMO reduces disability when compared with standard care. ECMO-Rehab trial is a registry embedded trial and will be utilising EXCEL data.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Intervention Group; ECMO early rehabilitation is led by a senior physiotherapist who has specialised training in ECMO care and coordinates individualised early physical training from randomisation to day 28 in ICU and liaises with the patient through to hospital discharge. The early rehabilitation intervention involves physical activity, functional retraining, strengthening exercises and mobilisation based on a reproducible, physiological approach.	Other: Early Rehabilitation; The intervention involves a progression of rehabilitation exercises with the objective of rehabilitating the patient at the highest level of exercise possible for the patient for the longest period of time that can be tolerated (up to 60 mins) at each session. The intervention will be administered 5 days per week (weekdays) while the patient remains in ICU, censored at 28 days after randomisation.
No Intervention: Control Group; The control group will receive standard care from nursing and physiotherapy staff not involved in the early, co-ordinated rehabilitation.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame

Organ failure free days to day 28		28 days post randomisation
Delirium-free days to day 28		28 days post randomisation
Activities of Daily Living (ADL) at hospital discharge		up to day of hospital discharge, an average of 3 months
Length of stay on ECMO, in ICU and in hospital		up to day of stay on ECMO, ICU and hospital, an average of 3 months
Mortality rate at ICU and hospital discharge, day 90 and day 180		up to 180 days post randomisation
Instrumental activities of daily living at 180 days	Physical function measured with instrumental activities of daily living	180 days post randomisation
Montreal Cognitive Assessment (MoCA-Blind)	Rapid screening instrument for mild cognitive dysfunction. Normal is equal or more than 18 points.	180 days post randomisation
