Brief summary
The objective of this study is to determine the feasibility of delivering a very early mobility rehabilitation program in Intensive Care Units (ICU), within the context of a randomised controlled trial (RCT). This will inform the design of a future RCT investigating very early ICU rehabilitation in the UK National Health Service.
Detailed description
Early ICU-based physical rehabilitation may benefit patients with acute severe respiratory failure by attenuating the development of severe and persistent weakness and impaired physical function seen in these patients. Muscle wasting occurs early (within 12 hours) and progresses rapidly after ICU admission. Patients may suffer from consequent physical impairment for months or years following their discharge. ICU based rehabilitation has the potential to improve physical function outcomes, through mitigating muscle wasting. The investigators have successfully introduced a very early ICU mobility program in their institution, which results in increased ventilator free days and reduced length of ICU stay. The primary aim is to investigate whether this method will work in other ICUs. EMPRESS will test the feasibility of running this intervention as an RCT. The results and a concurrent process evaluation will inform the design of a future, multi-centre randomised controlled trial.
Interventions
OTHEREarly mobility
This progressive mobility pathway commenced with passive cycling within 48 hours of intubation and ventilation and progressing through assisted cycling, active cycling, bed exercises, sitting, mobilising out of bed to walking

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Physical Function ICU Test-scored | Up to 28 days | This is a reliable and valid 4 item scale ( arm strength, leg strength, ability to stand and step cadence),with a score range of 0-10 and is responsive to change and predictive of key outcomes. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Hand held dynamometry (HHD) | Up to 12 weeks | Assessment of hand grip strength |
| Chelsea Critical Care Physical Assessment tool (CPAX) | Up to 28 days | This validated tool reliably grades physical morbidity from complete dependence on admission though progressive independence. Scores on ICU discharge may predict recovery trajectory. |
| ICU Mobility Scale | Up to 28 days | Best level of function achieved in ICU using an 11-point ordinal scale |
| Timed up and go | Up to 6 months | The Timed Up and Go test is a simple test used to assess a person's mobility and requires both static and dynamic balance. It uses the time that a person takes to rise from a chair, walk three meters, turn around, walk back to the chair, and sit down. |
| Clinical Frailty Score | Up to 6 months | An 8 point score to classify patients as fit, vulnerable or frail and correlates with outcome in both elderly and younger patients. Pre illness frailty will be assessed by proxy on admission from information gathered from family member /NOK and from patient at the 3 follow-up assessment |
| Medical Research Council Manual Muscle Test Sum Score ( MRC-ss) | Up to 28 days | Test of muscle strength and function, where full strength is defined as a score of 60/60 and ICU-AW as a score of \<48/60 |
| Six minute walk test | Up to 6 months | Widely used to assess functional exercise capacity in patients following an ICU admission |
| The Hospital Anxiety and Depression Scale - HADS | 6 months | Measure of anxiety and depression in general medical population of patients. Each item on the questionnaire is scored from 0-3 and this means that a person can score between 0 and 21 for either anxiety or depression. |
| WHO Disability Assessment Schedule 2.0 (WHODAS 2.0) | 6 months | A generic assessment instrument for health and disability |
| EQ-5D-5L | 6 months | The descriptive system comprises self-assessment of five dimensions of health: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. |
| Barthel Index for Activities of Daily Living | Up to 6 months | Barthel ADL index is an ordinal scale used to measure performance in activities of daily living (ADL). Each performance item is rated on this scale with a given number of points assigned to each level or ranking. It uses ten variables describing ADL and mobility. A higher number is associated with a greater likelihood of being able to live at home with a degree of independence following discharge from hospital. |
