Is the manchester mobility score a valid and reliable measure of physical function within the intensive care unit

Does the level of mobility on ICU discharge impact post-ICU outcomes? A retrospective analysis

PURPOSE

Mobilisation is a common intervention in Intensive Care (ICU). However, few studies have explored the relationship between mobility levels and outcomes. This study assessed the association of the level of mobility on ICU discharge with discharge destination from the hospital and hospital length of stay.

MATERIALS AND METHODS

A retrospective analysis of data from 522 patients admitted to a single UK general ICU who were ventilated for ≥5 days was performed. The level of mobility was assessed using the Manchester Mobility Score (MMS). Multivariable regression analysed demographic and clinical variables for the independence of association with discharge destination and hospital length of stay.

RESULTS

MMS ≥5 on ICU discharge was independently associated with discharge destination and hospital LOS (p < 0.001). Patients achieving MMS ≥5 on ICU discharge were more likely to be discharged home (OR 3.86 95% CI 2.1 to 6.9, p < 0.001), and had an 11.8 day shorter hospital LOS (95% CI -17.6 to -6.1, p < 0.001).

CONCLUSIONS

The ability to step transfer to a chair (MMS ≥5) before ICU discharge was independently associated with discharge to usual residence and hospital LOS, irrespective of preadmission morbidity. Increasing the level of patient mobility at ICU discharge should be a key focus of rehabilitation interventions.

Early rehabilitation and mobilisation of neonatal and paediatric extracorporeal membrane oxygenation patients: A UK and Ireland consensus document

Despite increasing early rehabilitation and mobilisation (ERM) in paediatric intensive care, current evidence for ERM of neonatal and paediatric patients receiving extracorporeal membrane oxygenation (ECMO) is limited. The proposed benefits of ERM in neonatal and paediatric ECMO patients are multifaceted, including reduced immobility related issues and maintenance of functional ability. However, ECMO presents additional safety and logistical challenges, and currently there are no published neonatal or paediatric guidelines. A consensus document was developed to provide guidance for ERM with neonatal and paediatric ECMO patients. The document was developed by specialist physiotherapists from nine ECMO centres within the UK and Ireland, together with the UK Paediatric Critical Care Society ECMO group and members of the multidisciplinary team. The document covers key considerations and practicalities for completing ERM in this population including, acuity level measurement, activity level guidance, safety and risk assessment, and goal setting. Risk assessment and safety checklist bedside tools are also included and designed to be adapted as required to meet specific unit policies and protocols.

Mobilisation in the EveNing to prevent and TreAt deLirium (MENTAL): a mixed-methods, randomised controlled feasibility trial

Background

Delirium is common in critically ill patients and associated with longer hospital stays, increased morbidity and higher healthcare costs. Non-pharmacological interventions have been advocated for delirium management, however there is little evidence evaluating feasibility and acceptability of physical interventions administered in the evening. The aim of this study was to conduct a feasibility trial of evening mobilisation to prevent and treat delirium in patients admitted to intensive care.

Methods

In this mixed-methods, randomised controlled feasibility trial we recruited participants from intensive care units at two university hospitals in the United Kingdom. Eligible participants who were able to respond to verbal stimulus (Richmond agitation and sedation scale ≥3) and expected to stay in intensive care for at least 24 h were randomly assigned (1:1) to receive usual care or usual care plus evening mobilisation. The evening mobilisation was delivered between 19:00 and 21:00, for up to seven consecutive evenings or ICU discharge, whichever was sooner. All outcome assessments were completed by a team member blinded to randomisation and group allocation. Primary objective was to assess feasibility and acceptability of evening mobilisation. Primary feasibility outcomes were recruitment, consent and retention rates, and intervention fidelity. Intervention acceptability was evaluated through semi-structured interviews of participants and staff. Secondary outcomes included prevalence in incidence and duration of delirium, measured using the Confusion Assessment Method for ICU. This trial is registered at ClinicalTrials.gov, NCT05401461.

Findings

Between July 16th, 2022, and October 31st, 2022, 58 eligible patients (29 usual care; 29 usual care plus evening mobilisation) were enrolled. We demonstrated the feasibility and acceptability of both the trial design and evening mobilisation intervention. Consent and retention rates over three months were 88% (58/66) and 90% (52/58) respectively, with qualitative analysis demonstrating good acceptability reported by both participants and staff. Secondary outcomes for the evening intervention group compared with the control group were: delirium incidence 5/26 (19%; 95% CI: 6-39%) vs 8/28 (29%; 95% CI: 13-49%) and mean delirium duration 2 days (SD 0.7) vs 4.25 days (SD 2.0).

Interpretation

Results of this trial will inform the development of a definitive full-scale randomised controlled trial investigating the effects of evening mobilisation to treat delirium and improve health-related outcomes.

Mobilisation in the EveNing to TreAt deLirium (MENTAL): protocol for a mixed-methods feasibility randomised controlled trial

INTRODUCTION

Delirium is common in critically ill patients and is associated with longer hospital stays, increased mortality and higher healthcare costs. A number of risk factors have been identified for the development of delirium in intensive care, two of which are sleep disturbance and immobilisation. Non-pharmacological interventions for the management of intensive care unit (ICU) delirium have been advocated, including sleep protocols and early mobilisation. However, there is a little published evidence evaluating the feasibility and acceptability of evening mobilisation.

METHODS AND ANALYSIS

Mobilisation in the EveNing to TreAt deLirium (MENTAL) is a two-centre, mixed-methods feasibility randomised controlled trial (RCT). Sixty patients will be recruited from ICUs at two acute NHS trusts and randomised on a 1:1 basis to receive additional evening mobilisation, delivered between 19:00 and 21:00, or standard care. The underpinning hypothesis is that the physical exertion associated with evening mobilisation will promote better sleep, subsequently having the potential to reduce delirium incidence. The primary objective is to assess the feasibility and acceptability of a future, multicentre RCT. The primary outcome measures, which will determine feasibility, are recruitment and retention rates, and intervention fidelity. Acceptability of the intervention will be evaluated through semi-structured interviews of participants and staff. Secondary outcome measures include collecting baseline, clinical and outcome data to inform the power calculations of a future definitive trial.

ETHICS AND DISSEMINATION

Ethical approval has been obtained through the Wales Research and Ethics Committee 6 (22/WA/0106). Participants are required to provide written informed consent. We aim to disseminate the findings through international conferences, international peer-reviewed journals and social media.

Time to active sitting position: One-year findings from a temporary COVID-19 intensive care unit

Objective

To investigate the association between time to active sitting position and clinical features in people with COVID-19 admitted to intensive care unit (ICU) and referred to physiotherapists.

Method

Prospective study conducted in the largest temporary ICU in Lombardy (Italy) between April 2020 and June 2021. All individuals with COVID-19 who received physiotherapy were included. Multivariable Cox proportional hazard model was fitted to explore the statistical association between active sitting position and characteristics of patients referred to physiotherapists, also accounting for the different multidisciplinary teams responsible for patients.

Results

284 individuals over 478 (59.4%) had access to physiotherapy, which was performed for a median of 8 days, without difference between multidisciplinary teams (P = 0.446). The active sitting position was reached after a median of 18 (IQR: 10.0–32.0) days. Sex was the only characteristic associated with the time to active sitting position, with males showing a reduced hazard by a factor of 0.65 (95% CI: 0.48–0.87; P = 0.0042) compared to females. At ICU discharge, nearly 50% individuals increased Manchester Mobility Score by 3 points. During physiotherapy no major adverse event was recorded.

Conclusion

Individuals with COVID-19 take long time to reach active sitting position in ICU, with males requiring longer rehabilitation than females.

Safety and feasibility of physiotherapy in ICU-admitted severe COVID-19 patients: an observational study

Early physiotherapy could play an important role in the management of severe COVID-19 subjects with consequences of prolonged ICU stay, although its effectiveness is still unclear. Aim of this study is to describe physiotherapy performed in severe COVID-19 patients and to evaluate its safety and feasibility. Consecutive adults with confirmed SARS-CoV-2 infection, admitted to the ICU, needing invasive mechanical ventilation for >24 hours and receiving early physiotherapy, have been enrolled. Adverse events occurred during physiotherapy sessions and timing and type of physiotherapy delivered were analysed, to identify the interventions most frequently performed and to determine the time taken to first mobilize, stand and walk. Functional and clinical assessment of patients was also performed at hospital discharge. Eighty-four severe COVID-19 subjects were enrolled. Few minor adverse events were recorded. Active mobilization was promoted over passive mobilization and independence in daily life activities was supported. Time interval from patients' intubation to the first physiotherapy treatment was 13 days and to walking was 27 days. Forty-eight (57.1%) subjects returned at home, whereas 29 (34.5%) were discharged to in-patient rehabilitation. Patients with tracheostomy experienced a delay in time from ICU admission until sit out of bed and ambulation, if compared with subjects without tracheostomy, although no differences were found in 6MWT and 1m-STST performances. This study reporting early physiotherapy during pandemic suggests that this intervention is feasible and safe for severe COVID-19 subjects, as well as healthcare workers, although delayed compared to other critically ill patients.

Muscle strength and functional outcome after prone positioning in COVID-19 ICU survivors

Objective

To evaluate the muscle strength and functional level of patients discharged from intensive care unit (ICU) in relation to the swimmer position as a nurse intervention during pronation.

Methods

Prospective study conducted in the hub COVID-19 center in Milan (Italy), between March and June 2020. All patients with COVID-19 discharged alive from ICU who received invasive mechanical ventilation were included. Forward continuation ratio model was fitted to explore the statistical association between muscle strength grades and body positioning during ICU stay.

Results

Over the 128 patients admitted to ICU, 87 patients were discharged alive from ICU, with available follow-up measures at hospital discharge. Thirty-four patients (39.1%) were treated with prone positioning as rescue therapy, for a total of 106 pronation cycles with a median duration of 72 (IQR 60–83) hours. Prone positioning did not influence the odds of showing particular level of muscle strength, in any of the evaluated districts, namely shoulder (OR 1.34, 95%CI:0.61–2.97), elbow (OR 1.10, 95%CI:0.45–2.68) and wrist (OR 0.97, 95%CI:0.58–1.63). Only in the shoulder district, age showed evidence of association with strength (OR 1.06, 95%CI:1.02–1.10), affecting people as they get older. No significant sequalae related to swimmer position were reported by physiotherapists or nurses.

Conclusion

Swimmer position adopted during prone ventilation is not associated with worse upper limb strength or poor mobility level in COVID-19 survivors after hospital discharge.

Evaluating physical functioning in critical care: considerations for clinical practice and research

The evaluation of physical functioning is valuable in the intensive care unit (ICU) to help inform patient recovery after critical illness, to identify patients who may require rehabilitation interventions, and to monitor responsiveness to such interventions. This viewpoint article discusses: (1) the concept of physical functioning with reference to the World Health Organization International Classification of Functioning, Disability and Health; (2) the importance of measuring physical functioning in the ICU; and (3) methods for evaluating physical functioning in the ICU. Recommendations for clinical practice and research are made, along with discussion of future directions.

A comparison of earlier and enhanced rehabilitation of mechanically ventilated patients in critical care compared to standard care (REHAB): study protocol for a single-site randomised controlled feasibility trial

BACKGROUND

Mortality from critical illness is improving, but survivors suffer from prolonged weakness and psychological and cognitive impairments. Maximising the recovery after critical illness has been highlighted as a research priority, especially in relation to an ageing population who present with higher rates of pre-morbid disability. Small studies have shown that starting rehabilitation early within the intensive care unit (ICU) improves short-term outcomes. Systematic reviews have highlighted the need for robust multicentre randomised controlled trials with longer term follow-up.

METHODS

The study design is a randomised controlled study to explore the feasibility of providing earlier and enhanced rehabilitation to mechanically ventilated patients at high risk of ICU-acquired weakness within the ICU. The rehabilitation intervention involves a structured programme, with progression along a functionally based mobility protocol according to set safety criteria. The overall aim of the intervention is to commence mobilisation at an earlier time point in the patient's illness and increase mobility of the patient through their recovery trajectory. Participants will be randomised to enhanced rehabilitation or standard care, with the aim of recruiting at least 100 patients over 16 months. The trial design will assess recruitment and consent rates from eligible patients, compliance with the intervention, and assess a range of possible outcome measures for use in a definitive trial, with follow-up continuing for 12 months post hospital discharge.

DISCUSSION

This study will evaluate the feasibility of providing an earlier and enhanced rehabilitation intervention to mechanically ventilated patients in critical care. We will identify strengths and weaknesses of the proposed protocol and the utility and characteristics of the outcome measures. The results from this study will inform the design of a phase III multicentre trial of enhanced rehabilitation for critically ill adults.
