de Morton Mobility Index Is Feasible, Reliable, and Valid in Patients With Critical Illness

Metabolic load during morning care and active bed exercises in critically ill patients: An explorative study

BACKGROUND

To avoid overexertion in critically ill patients, information on the physical demand, i.e., metabolic load, of daily care and active exercises is warranted.

OBJECTIVE

The objective of this study was toassess the metabolic load during morning care activities and active bed exercises in mechanically ventilated critically ill patients.

METHODS

This study incorporated an explorative observational study executed in a university hospital intensive care unit. Oxygen consumption (VO2) was measured in mechanically ventilated (≥48 h) critically ill patients during rest, routine morning care, and active bed exercises. We aimed to describe and compare VO2 in terms of absolute VO2 (mL) defined as the VO2 attributable to the activity and relative VO2 in mL per kilogram bodyweight, per minute (mL/kg/min). Additional outcomes achieved during the activity were perceived exertion, respiratory variables, and the highest VO2 values. Changes in VO2 and activity duration were tested using paired tests.

RESULTS

Twenty-one patients were included with a mean (standard deviation) age of 59 y (12). Median (interquartile range [IQR]) durations of morning care and active bed exercises were 26 min (21-29) and 7 min (5-12), respectively. Absolute VO2 of morning care was significantly higher than that of active bed exercises (p = 0,009). Median (IQR) relative VO2 was 2.9 (2.6-3.8) mL/kg/min during rest; 3.1 (2.8-3.7) mL/kg/min during morning care; and 3.2 (2.7-4) mL/kg/min during active bed exercises. The highest VO2 value was 4.9 (4.2-5.7) mL/kg/min during morning care and 3.7 (3.2-5.3) mL/kg/min during active bed exercises. Median (IQR) perceived exertion on the 6-20 Borg scale was 12 (10.3-14.5) during morning care (n = 8) and 13.5 (11-15) during active bed exercises (n = 6).

CONCLUSION

Absolute VO2 in mechanically ventilated patients may be higher during morning care than during active bed exercises due to the longer duration of the activity. Intensive care unit clinicians should be aware that daily-care activities may cause intervals of high metabolic load and high ratings of perceived exertion.

Protein and energy intake in intensive care unit survivors during the first year of recovery: A descriptive cohort study

BACKGROUND

Many intensive care unit (ICU) survivors suffer long-term health issues that affect their quality of life. Nutrition inadequacy can limit their rehabilitation potential. This study investigates nutrition intake and support during ICU admission and recovery.

METHODS

In this prospective cohort study, 81 adult ICU patients with stays ≥48 h were included. Data on dietary intake, feeding strategies, baseline and ICU characteristics, and 1-year outcomes (physical health and readmission rates) were collected. The number of patients achieving 1.2 gram per kilogram per day of protein and 25 kilocalories per kilogram per day at 3 months, 6 months, and 12 months after ICU admission was recorded. The impact of dietary supplementation during the year was assessed. Baseline characteristics, intake barriers, and rehabilitation's influence on nutrition intake at 12 months were evaluated, along with the effect of inadequate intake on outcomes.

RESULTS

After 12 months, only 10% of 60 patients achieved 1.2 g/kg/day protein intake, whereas 28% reached the advised 25 kcal/kg/day energy target. Supplementary feeding significantly increased protein intake at 3, 6, and 12 months (P = 0.003, P = 0.012, and P = 0.033, respectively) and energy intake at 3 months (P = 0.003). A positive relation was found between female sex and energy intake at 12 months after ICU admission (β = 4.145; P = 0.043) and taste issues were independently associated with higher protein intake (β = 0.363; P = 0.036). However, achieving upper-quartile protein or energy intake did not translate into improved physical health outcomes.

CONCLUSION

Continuous and improved nutrition care is urgently needed to support patients in reaching nutrition adequacy.

Clinimetric properties of the Turkish version of the De-Morton Mobility Index (DEMMI) in intensive care unit survivors - a cross-sectional observational study

PURPOSE

To investigate the intra-rater reliability and the construct validity of the Turkish version of the De-Morton Mobility Index (DEMMI) in intensive care unit (ICU) survivors.

METHODS

Construct validity of the DEMMI was measured by correlating it with physical functioning scales. Known group comparison was made according to the Medical Research Council Sum Score (MRC-SS). Internal consistency was determined by measuring Cronbach α coefficient. Test-retest reliability was assessed by performing the DEMMI by the same researcher after 24 h and calculating the intraclass correlation coefficient (ICC). The minimal detectable change (MDC) value was calculated.

RESULTS

One hundred and two patients discharged from the ICU were included. The ICC for intra-reliability was 0.972. The internal consistency was excellent (Cronbach = 0.991). The DEMMI total score was correlated with the Barthel Index (r = 0.791), Katz Index of Independence in Activities of Daily Living (r = 0.722), MRC-SS (0.614), ICU length of stay (r = -0.515), and total mechanical ventilation duration (r = -0.488). The DEMMI was able to differentiate between MRC-SS subgroups (p < 0.001), whereby higher strength was associated with higher DEMMI scores. The MDC was determined to be 6.82 out of 100 points.

CONCLUSION

The Turkish version of the DEMMI is reliable and valid for measuring mobility in ICU survivors.

TRIAL REGISTRATION NUMBER

NCT05196997Implications for RehabilitationThe Turkish version of the de-Morton Mobility Index (DEMMI) is a reliable and valid outcome measure for the assessment of functional mobility in intensive care unit survivors.The Turkish version of the DEMMI could guide clinicians working in the field of intensive care in the planning of rehabilitation programs after discharge.

Health-related quality-of-life during rehabilitation in patients with critical illness neuropathy/myopathy after severe coronavirus disease 2019

Our aim was to evaluate health-related quality-of-life (HRQoL) of the patients with critical illness neuropathy and/or myopathy after severe COVID-19 during their rehabilitation. The prospective cohort study included 157 patients (median age 64 years) admitted to rehabilitation. HRQoL was assessed the using European Quality 5-Dimensions questionnaire [EQ-5D index , range 0(or exceptionally less) to 1, and Visual Analogue Scale (VAS), range 0-100], which was completed by the patients at admission and discharge. Additionally, they were assessed with the de Morton Mobility Index (DEMMI), the 6-Minute Walk Test (6MWT), and the Functional Independence Measure (FIM). Median EQ-5D index was 0.32 and median EQ VAS was 48 at admission, and median EQ-5D index was 0.61 and median EQ VAS 80 at discharge. Some or extreme problems were reported by 154 (98%) patients regarding the mobility dimension, 151 (96%) regarding usual activities, 136 (87%) regarding self-care, 84 (54%) regarding pain or discomfort dimension, and 52 patients (34%) regarding anxiety or depression at admission. At discharge, some or extreme problems were still reported by 96 patients (61%) regarding mobility, 95 (61%) regarding usual activities, 70 patients (45%) regarding pain or discomfort, 46 (29%) regarding self-care, and 19 patients (12%) regarding anxiety or depression. At the same time, the patients exhibited significant improvements in the DEMMI (median increased from 41 to 67 points), 6MWT (from 60 to 293 m) and motor FIM (from 56 to 84 points). The improvement of the self-reported HRQoL was, thus, paralleled by the improvements in clinician-assessed mobility, walking endurance and functional independence.

Physical recovery across care pathways up to 12 months after hospitalization for COVID-19: A multicenter prospective cohort study (CO-FLOW)

Backgroud

The sudden COVID-19 pandemic forced quick development of care pathways for patients with different needs. Trajectories of physical recovery in hospitalized patients for COVID-19 following different care pathways are unknown. We aimed to assess trajectories of physical recovery and levels of physical function reached within the different care pathways. Additionally, we assessed differences in physical function across care pathways at follow-up visits.

Methods

This multicenter prospective cohort study of adults who had been hospitalized for COVID-19 was performed in 10 centers, including 7 hospitals (1 academic and 6 regional hospitals) and 3 rehabilitation centers (1 medical rehabilitation center and 2 skilled nursing facilities), located in the Netherlands. Study visits were performed at 3, 6, and 12 months post-hospital discharge and included assessment of cardiorespiratory fitness (6 min walk test [6MWT], 1 min sit-to-stand test [1MSTST]), muscle strength (maximum handgrip strength [HGS]) and mobility (de Morton Mobility Index [DEMMI]).

Findings

We report findings for 582 patients who had been discharged from hospital between March 24, 2020 and June 17, 2021. Patients had a median age of 60·0 years, 68·9% (401/582) were male, 94·6% (561/582) had received oxygen therapy, and 35·2% (205/582) mechanical ventilation. We followed patients across four different rehabilitation settings: no rehabilitation (No-rehab, 19·6% [114/582]), community-based rehabilitation (Com-rehab, 54·1% [315/582]), medical rehabilitation (Med-rehab, 13·7% [80/582]), and rehabilitation in a skilled nursing facility (SNF-rehab, 12·5% [73/582]). Overall, outcomes in 6MWT (14·9 meters [95% CI 7·4 to 22·4]), 1MSTST (2·2 repetitions [1·5 to 2·8]), and HGS (3·5 kg [2·9 to 4·0]) improved significantly (p<0·001) from 3 to 6 months and only HGS from 6 to 12 months (2·5 kg [1·8 to 3·1]; p<0·001). DEMMI scores did not significantly improve over time. At 3 months, percentage of normative values reached in 1MSTST differed significantly (p<0.001) across care pathways, with largest impairments in Med- and SNF-rehab groups. At 12 months these differences were no longer significant, reaching, overall, 90·5% on 6MWD, 75·4% on 1MSTST, and 106·9% on HGS.

Interpretation

Overall, physical function improved after hospitalization for COVID-19, with largest improvement within 6 months post-discharge. Patients with rehabilitation after hospital discharge improved in more than one component of physical function, whereas patients without rehabilitation improved solely in muscle strength. Patients who received rehabilitation, and particularly patients with Med- and SNF-rehab, had more severe impairment in physical function at 3 months, but reached equal levels at 12 months compared to patients without follow-up treatment. Our findings indicate the importance of rehabilitation.

Functional assessment and rehabilitation protocol in acute patients affected by SARS-CoV-2 infection hospitalized in the Intensive Care Unit and in the Medical Care Unit

BACKGROUND

Coronavirus disease (COVID-19) is characterized by different clinical pictures that may require prolonged hospitalization and produce disabilities challenging the recovery of previous independence.

AIM

The aim is to evaluate the impact of an early assisted rehabilitation program on the functional status of an acutely hospitalized population affected by COVID-19.

DESIGN

Single-institution retrospective longitudinal study.

SETTING

Inpatient intensive care units (ICU) and medical care units (MCU).

POPULATION

Acute COVID-19 patients.

METHODS

General information was collected; age-adjusted Charlson Comorbidity Index was used for comorbidities. Duration of hospital stay, the length of stay in ICU and/or MCU, the length of the rehabilitative treatment, and the destination at the discharge were collected. Evaluation was performed when patients were clinically stable (T0), and at hospital discharge (T1); for subjects enrolled in ICU functional status was assessed at the time of transfer to the MCU. Muscle strength of the four limbs was measured with the Medical Research Council (MRC) sum-score. Functional status was assessed using the 3-item Barthel Index (BI-3) and the General Physical Mobility Score (GPMS). Early assisted-tailored rehabilitation protocol was applied in ICU and in MCU: the aims were the maintenance (or recovery) of the range of motion and of the strength and the recovery of sitting/standing position and gait.

RESULTS

We evaluated 116 patients (mean age 65, SD 11) (65% male), 68 in ICU (mean age 60, SD 10), 48 in MCU (mean age 73, SD 9). At discharge, BI-3 and GPMS significantly improved in both ICU (P<0.001) and MCU (P<0.001) subgroups of patients. MRC sum-score significantly improved in ICU patients (P<0.001). Patients hospitalized in ICU had a significantly longer hospital stay. At discharge, patients admitted to the ICU reach a functional state that is close to that of patients admitted to the MCU.

CONCLUSIONS

The results suggest that an early assisted rehabilitation program may be helpful in improving the short-term functional status of an acutely hospitalized population affected by COVID-19, with discharge at home of 48% CLINICAL REHABILITATION IMPACT: this study focuses on a functional assessment method to be used to identify the rehabilitation needs and verify the results of an early rehabilitation protocol applied to the acute COVID-19 patient admitted to ICU and MCU.

Rehabilitation of COVID-19 patients with respiratory failure and critical illness disease in Slovenia: an observational study

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection often causes pneumonia and respiratory failure that may lead to postintensive care syndrome, including critical illness neuropathy (CIN) and critical illness myopathy (CIM). The data on the rehabilitation outcomes of post-novel coronavirus disease (COVID) patients with CIN and CIM following respiratory failure and mechanical ventilation are still limited. To address this, we enrolled in our prospective observational study a sample of 50 consecutive COVID-19 patients admitted to our facility between 2 November 2020 and 3 May 2021 with electrophysiologically confirmed or clinically suspected diagnosis of CIN/CIM. The functional abilities were assessed at admission and discharge with the Functional Independence Measure (FIM), The Canadian Occupational Performance Measure, 10-metre walk test, 6-min walk test and the de Morton Mobility Index. The gain in motor FIM and the length of stay were used as an index of rehabilitation efficiency. Nutritional status was also assessed using anthropometric measurements and bioelectrical Impedance analysis. Psychologic evaluation was performed at admission only. At admission, functional limitations and severe malnutrition were present in all patients with psychologic problems in about one third. At discharge (42 ± 16 days later), clinically important and statistically significant improvements were found in all outcome measures, which was also noted by the patients. The gain in motor FIM was larger with the longer length of stay up to 2 months and plateaued thereafter. We conclude that post-COVID-19 patients who develop CIN/CIM following respiratory failure can improve functional and nutritional status during inpatient rehabilitation.

A generic outcome assessment of mobility capacity in neurorehabilitation: measurement properties of the de Morton Mobility Index

Background

Mobility capacity is a key outcome domain in neurorehabilitation. The de Morton Mobility Index (DEMMI), an established and generic outcome assessment of mobility capacity in older patients, is promising for use in neurorehabilitation. The aim of this study was to examine the measurement properties of the DEMMI in rehabilitation inpatients with neurological conditions.

Methods

Cross-sectional study including a mixed sample of adult inpatients in a neurorehabilitation hospital. Structural validity, unidimensionality and measurement invariance (Rasch analysis), construct validity, internal consistency reliability, and inter-rater reliability of the DEMMI (scale range: 0–100 points) were established. The minimal detectable change, the 95% limits of agreement, and possible floor and ceiling effects were calculated to indicate interpretability.

Results

We analyzed validity (n = 348) and reliability (n = 133) in two samples. In both samples, the majority of participants had a sub-acute stroke or Parkinson’s disease.

Rasch analysis indicated unidimensionality with an overall fit to the model (chi-square = 59.4, P = 0.074). There was no relevant measurement invariance by disease group. Hypotheses-based correlation analyses (DEMMI and other functional outcome assessments) showed sufficient construct validity. Internal consistency reliability (Cronbach’s alpha = 0.94) and inter-rater reliability (intraclass correlation coefficient = 0.94; 95% confidence interval: 0.91–0.95) were sufficient. The minimal detectable change with 90% confidence was 15.0 points and the limits of agreement were 39%. No floor or ceiling effects were observed.

Conclusions

Results indicate sufficient measurement properties of the DEMMI in rehabilitation inpatients with neurological conditions. The DEMMI can be used as a generic outcome assessment of mobility capacity in neurorehabilitation.

Functional Status After Pulmonary Rehabilitation as a Predictor of Weaning Success and Survival in Patients Requiring Prolonged Mechanical Ventilation

Background: Comprehensive rehabilitation programs are recommended for patients with prolonged mechanical ventilation (PMV) to facilitate functional recovery and ventilator weaning, but whether the functional status after rehabilitation influences outcome has not been clearly evaluated. This study aimed to investigate the association between post-rehabilitation functional status and weaning and survival outcome in PMV patients. Methods: We retrospectively enrolled PMV patients admitted to the respiratory care center (RCC), a post-ICU weaning facility with protocolized rehabilitation program, from January 2016 through December 2017. Functional status was measured by the de Morton Mobility Index (DEMMI), with a cut-off value set at 20 points. The primary outcomes were the weaning status at RCC discharge and hospital survival. The secondary outcomes were overall survival and survival at 3 months after RCC discharge. We followed patients until 3 months after RCC discharge or death. Logistic and Cox regressions were performed to identify significant parameters associated with weaning success and survival. Results: In total, 320 patients were enrolled. The weaning success rate was 71.6%. The survival rate at RCC discharge, hospital discharge, and 3 months after RCC discharge was 89.1, 77.5, and 66.6%, respectively. Post-rehabilitation DEMMI ≥ 20 (odds ratio [OR], 3.514; 95% confidence interval [CI], 1.436-8.598; P = 0.006) was the most significantly associated with weaning success. The weaning success and higher post-rehabilitation DEMMI were the two most significant independent factors associated with both hospital survival (weaning success, OR, 12.272; 95% CI, 5.281-28.517; P < 0.001; post-rehabilitation DEMMI ≥ 20, OR, 6.298; 95% CI, 1.302-30.477; P = 0.022) and survival at 3 months after RCC discharge (weaning success, OR, 38.788; 95% CI, 11.505-130.762; P < 0.001; post-rehabilitation DEMMI ≥ 20, OR, 4.830; 95% CI, 1.072-21.756; P = 0.040). Post-rehabilitation DEMMI ≥ 20 remained significantly association with overall survival at 3 months after RCC discharge (hazard ratio, 0.237; 95% CI, 0.072-0.785; P = 0.018). Conclusions: Post-rehabilitation functional status of PMV patients was independently associated with weaning success, as well as hospital and 3-month overall survival after RCC discharge. Post-rehabilitation, but not pre-rehabilitation, functional status was a significant parameter associated with weaning success and survival in patients requiring PMV.

Evaluating Physical Functioning in Survivors of Critical Illness: Development of a New Continuum Measure for Acute Care

OBJECTIVES

Evaluation of physical functioning is central to patient recovery from critical illness-it may enable the ability to determine recovery trajectories, evaluate rehabilitation efficacy, and predict individuals at highest risk of ongoing disability. The Physical Function in ICU Test-scored is one of four recommended physical functioning tools for use within the ICU; however, its utility outside the ICU is poorly understood. The De Morton Mobility Index is a common geriatric mobility tool, which has had limited evaluation in the ICU population. For the field to be able to track physical functioning recovery, we need a measurement tool that can be used in the ICU and post-ICU setting to accurately measure physical recovery. Therefore, this study sought to: 1) examine the clinimetric properties of two measures (Physical Function in ICU Test-scored and De Morton Mobility Index) and 2) transform these measures into a single measure for use across the acute care continuum.

DESIGN

Clinimetric analysis.

SETTING

Multicenter study across four hospitals in three countries (Australia, Singapore, and Brazil).

PATIENTS

One hundred fifty-one ICU patients.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Physical function tests (Physical Function in ICU Test-scored and De Morton Mobility Index) were assessed at ICU awakening, ICU, and hospital discharge. A significant floor effect was observed for the De Morton Mobility Index at awakening (23%) and minimal ceiling effects across all time points (5-12%). Minimal floor effects were observed for the Physical Function in ICU Test-scored across all time points (1-7%) and a significant ceiling effect for Physical Function in ICU Test-scored at hospital discharge (27%). Both measures had strong concurrent validity, responsiveness, and were predictive of home discharge. A new measure was developed using Rasch analytical principles, which involves 10 items (scored out of 19) with minimal floor/ceiling effects.

CONCLUSIONS

Limitations exist for Physical Function in ICU Test-scored and De Morton Mobility Index when used in isolation. A new single measure was developed for use across the acute care continuum.

Chinesisation, adaptation and validation of the Chelsea Critical Care Physical Assessment Tool in critically ill patients: a cross-sectional observational study

PURPOSE

To translate and adapt the Chelsea Critical Care Physical Assessment Tool (CPAx) into Chinese version ('CPAx-Chi'), test the reliability and validity of CPAx-Chi, and verify the cut-off point for the diagnosis of intensive care unit-acquired weakness (ICU-AW).

STUDY DESIGN

Cross-sectional observational study.

METHODS

Forward and back translation, cross-cultural adaptation and pretesting of CPAx into CPAx-Chi were based on the Brislin model. Participants were recruited from the general ICU of five third-grade class-A hospitals in western China. Two hundred critically ill adult patients (median age: 53 years; 64% men) with duration of ICU stay ≥48 hours and Glasgow Coma Scale ≥11 were included in this study. Two researchers simultaneously and independently assessed eligible patients using the Medical Research Council Muscle Score (MRC-Score) and CPAx-Chi.

RESULTS

The content validity index of items was 0.889. The content validity index of scale was 0.955. Taking the MRC-Score scale as standard, the criterion validity of CPAx-Chi was r=0.758 (p<0.001) for researcher A, and r=0.65 (p<0.001) for researcher B. Cronbach's α was 0.939. The inter-rater reliability was 0.902 (p<0.001). The area under the receiver operating characteristic curves of CPAx-Chi for diagnosing ICU-AW based on MRC-Score ≤48 were 0.899 (95% CI 0.862 to 1.025) and 0.874 (95% CI 0.824 to 0.925) for researcher B. The best cut-off point for CPAx-Chi for the diagnosis of ICU-AW was 31.5. The sensitivity was 87% and specificity was 77% for researcher A, whereas it was 0.621, 31.5, 75% and 87% for researcher B, respectively. The consistency was high when taking CPAx-Chi ≤31 and MRC-Score ≤48 as the cut-off points for the diagnosis of ICU-AW. Cohen's kappa=0.845 (p=0.02) in researcher A and 0.839 (p=0.04) for researcher B.

CONCLUSIONS

CPAx-Chi demonstrated content validity, criterion-related validity and reliability. CPAx-Chi showed the best accuracy in assessment of patients at risk of ICU-AW with good sensitivity and specificity at a recommended cut-off of 31.

Patient-reported physical functioning is limited in almost half of critical illness survivors 1-year after ICU-admission: A retrospective single-centre study

Post-intensive care unit (ICU) sequelae, including physical and mental health problems, are relatively unexplored. Characteristics commonly used to predict outcome lack prognostic value when it comes to long-term physical recovery. Therefore, the objective of this study was to assess the incidence of non-recovery in long-stay ICU-patients. In this single-centre study, retrospective data of adults with an ICU stay >48 hours who visited the specialized post-ICU clinic, and completed the Dutch RAND 36-item Short Form questionnaire at 3 and 12 months post-ICU, were retrieved from electronic patient records. In cases where physical functioning scores at 12 months were below reference values, patients were allocated to the physical non-recovery (NR) group. Significantly different baseline and (post-)ICU-characteristics were assessed for correlations with physical recovery at 12 months post-ICU. Of 250 patients, 110 (44%) fulfilled the criteria for the NR-group. Neither the severity of illness, type of admission, nor presence of sepsis did not differ between groups. However, NR-patients had a higher age, were more often female, and had a higher incidence of co-morbidities. Shorter LOS ICU, lower incidence of medical comorbidities, and better physical performance at 3 months were significantly correlated with 1-year physical recovery. Comorbidities and reduced physical functioning at 3 months were identified as independent risk-factors for long-term physical non-recovery. In conclusion, a substantial proportion of long-stay ICU-patients who visited the standard care post-ICU clinic did not fulfil the criteria for full physical recovery at 12 months post-ICU. Commonly used ICU-characteristics, such as severity of illness, do not have sufficient prognostic value when it comes to long-term recovery of health-related quality of life.

Steps to recovery: body weight-supported treadmill training for critically ill patients: a randomized controlled trial

BACKGROUND

Early mobilization has been proven effective for patients in intensive care units (ICUs) to improve functional recovery. However, early mobilization of critically ill, often mechanically ventilated, patients is cumbersome because of the attachment to tubes, drains, monitoring devices and muscle weakness. A mobile treadmill with bodyweight support may help to initiate mobilization earlier and more effectively. The aim of this study is to assess the effectiveness of weight-supported treadmill training in critically ill patients during and after ICU stay on time to independent functional ambulation.

METHODS

In this randomized controlled trial, a custom-built bedside body weight-supported treadmill will be used and evaluated. Patients are included if they have been mechanically ventilated for at least 48 hours, are able to follow instructions, have quadriceps muscle strength of Medical Research Council sum-score 2 (MRC 2) or higher, can sit unsupported and meet the safety criteria for physical exercise. Exclusion criteria are language barriers, no prior walking ability, contraindications for physiotherapy or a neurological condition as reason for ICU admission. We aim to include 88 patients and randomize them into either the intervention or the control group. The intervention group will receive usual care plus bodyweight-supported treadmill training (BWSTT) daily. The BWSSTT consists of walking on a mobile treadmill while supported by a harness. The control group will receive usual care physiotherapy treatment daily consisting of progressive activities such as bed-cycling and active functional training exercises. In both groups, we will aim for a total of 40 minutes of physiotherapy treatment time every day in one or two sessions, as tolerated by the patient. The primary outcome is time to functional ambulation as measured in days, secondary outcomes include walking distance, muscle strength, status of functional mobility and symptoms of post-traumatic stress. All measurements will be done by assessors who are blinded to the intervention on the regular wards until hospital discharge.

DISCUSSION

This will be the first study comparing the effects of BWSTT and conventional physiotherapy for critically ill patients during and after ICU stay. The results of this study contribute to a better understanding of the effectiveness of early physiotherapy interventions for critically ill patients.

Mobility and clinical outcome of patients admitted to an intensive care unit

Abstract Introduction: The hospital environment exacerbates the effects of immobility due to several exposure factors, and the functional assessment of individuals using reliable instruments is vital. Objective: To determine the relationship between functional mobility and the clinical outcome of patients admitted to an intensive care unit. Method: This is a prospective quantitative longitudinal study, approved by the institutional research ethics committee, carried out in the intensive care unit of a University Hospital. Clinical data and the Acute Physiology and Chronic Health Evaluation (APACHE II) score were collected 24 hours after admission. The Perne Score was used to analyze patient mobility. Results: 33 patients participated, 63% female. With respect to mobility and transfers, 69.7% required total assistance from the supine to the sitting position and 70% to maintain balance, 9.1% needed minimum assistance from sitting to standing, and 100% total assistance for walking and endurance exercises. The main barriers to mobility were invasive ventilation (60%), assistive devices and intravenous infusion (100%). The following Perne Score domains were significantly associated with the outcome: mental status (p = 0.040), barriers to mobility (p = 0.016), strength (p = 0.010), mobility in bed (p = 0.024) and the total Perme Score ( p = 0.002). There were also significant associations between invasive ventilation and low Perme Scores (p = 0.000), and the Richmond Agitation-Sedation Scale (RASS) (-5 and -4) and death in 66.7% of patients (p = 0.011). The Perme Score and RASS (R = 0.745) were moderately correlated and APACHE II and Perme Score inversely moderately correlated (R = -0.526). Conclusion: Mobility assessed by the Perme Score was related to the clinical outcome and strongly associated with sedation level and patient severity.

Feasibility of de Morton Mobility Index for adult patients of all ages at low and basic functioning level: a study using the Slovenian translation

We investigated metric properties of the Slovenian translation of de Morton Mobility Index in patients with musculoskeletal impairments during rehabilitation. The study included 30 inpatients, aged 22-84 years, with musculoskeletal impairments with or without impairment of peripheral nerves. They were assessed repeatedly with de Morton Mobility Index, Functional Ambulation Classification, Ten-metre Walk Test, Six-minute Walk Test, Berg Balance Scale and the motor subscale of the Functional Independence Measure. Convergent validity of de Morton Mobility Index was confirmed by good to very good correlations with the other measurements. Known-groups validity was demonstrated by significant differences in de Morton Mobility Index scores between patients who were not able to walk and those who were able to walk with or without waking aid, at admission and after 4 weeks. Predictive validity of de Morton Mobility Index for functional independence after 4 weeks of rehabilitation was moderate. Minimal clinically important difference of de Morton Mobility Index was estimated to be five points. De Morton Mobility Index was responsive after 2 and 4 weeks of rehabilitation (Cohen's d 1.15 and 0.95, respectively). No floor or ceiling effects were identified. Internal validity of de Morton Mobility Index was confirmed by Rasch analysis. Hence, de Morton Mobility Index is a valid, unidimensional, and responsive measure of mobility for patients with musculoskeletal impairments at rehabilitation regardless of age. Its use is recommended for adult patients at low and basic functioning level.

Feasibility of Muscle Activity Assessment With Surface Electromyography During Bed Cycling Exercise In Intensive Care Unit Patients

Introduction: Intensive care unit (ICU) patients often develop weakness. Rehabilitation is initiated early to prevent physical deterioration, but knowledge of optimal training schedules is lacking. A reliable method to assess muscle activity during exercise is needed. In this study we explored the feasibility of electrical activity measurement by surface electromyography (sEMG) during bed cycling in ICU patients. Methods: SEMG was performed in 9 ICU patients and 6 healthy controls. A standardized 1‐minute incremental resistance bedside cycle ergometer protocol was used. Results: The median cycle time was 5.3 minutes in patients and 12.0 minutes in controls. The maximum sEMG increased in both groups; the minimal sEMG activity remained the same in patients, whereas an increase in the control group was found. Discussion: sEMG is feasible and can detect muscle activity during bed cycling in ICU patients. It may be a useful monitoring tool. Repeated measurements could possibly provide information on the effects of training. Muscle Nerve58: 688–693, 2018

Impact of the Chelsea critical care physical assessment (CPAx) tool on clinical outcomes of surgical and trauma patients in an intensive care unit: An experimental study

Background

Critically ill patients following traumatic injury or major surgery are at risk of loss of skeletal muscle mass, which leads to decreased physical function. Early rehabilitation in an intensive care unit (ICU) is thought to preserve or restore physical functioning. The Chelsea critical care physical assessment (CPAx) is a measurement tool used to assess physical function in the ICU.

Objectives

To determine whether the use of the CPAx tool as part of physiotherapy patient assessment, in two adult trauma and surgical ICU settings where early patient mobilisation forms part of standard physiotherapy practice, had an impact on ICU and hospital length of stay (LOS) through delivery of problem-oriented treatment plans.

Method

A single-centred pre–post quasi-experimental study was conducted. The population was a consecutive sample of surgical and trauma ICU patients. Participants’ functional ability was assessed with the CPAx tool on alternative days during their ICU stay, and rehabilitation goals were modified according to their CPAx score. Intensive care unit and hospital LOS data were collected and compared to data of a matched historical control group. Descriptive and inferential statistics were used.

Results

A total of 26 ICU patients were included in the intervention group (n = 26). They received CPAx-guided therapy, and outcomes were matched with ICU patients in the historical control group (n = 26). The median sequential organ failure assessment (SOFA) score was significantly higher in the control group (p = 0.005) (3.5 [IQR 2–6.3]) versus (2 [IQR 1.8–2.5]) for the intervention group. The median admission CPAx score for the intervention group was 33.5 (IQR 16.1–44), and the median ICU discharge score was 38 (IQR 28.5–43.8). No significant differences were found in ICU days (control 2.7 [IQR 1.1–5.2]; intervention 3.7 [IQR 2.3–5.4]; p = 0.27) or hospital LOS (control 13.5 [IQR 9.3–18.3]; intervention 11.4 [IQR 8.4–20.3], p = 0.42). Chelsea critical care physical assessment scores on ICU admission had a moderate negative correlation with hospital LOS (r = −0.58, p = 0.00, n = 23). Chelsea critical care physical assessment scores at ICU discharge had strong positive correlation with discharge SOFA scores (r = 0.7; p = 0.025; n = 10).

Conclusion

Problem-oriented patient rehabilitation informed by the CPAx tool resulted in improvement of physical function but did not reduce ICU or hospital LOS.

Clinical implications

A higher level of physical function at ICU admission, measured with CPAx, was associated with shorter hospital LOS.

Construct validity and inter-rater reliability of the Dutch activity measure for post-acute care "6-clicks" basic mobility form to assess the mobility of hospitalized patients

To evaluate the construct validity and the inter-rater reliability of the Dutch Activity Measure for Post-Acute Care "6-clicks" Basic Mobility short form measuring the patient's mobility in Dutch hospital care. First, the "6-clicks" was translated by using a forward-backward translation protocol. Next, 64 patients were assessed by the physiotherapist to determine the validity while being admitted to the Internal Medicine wards of a university medical center. Six hypotheses were tested regarding the construct "mobility" which showed that: Better "6-clicks" scores were related to less restrictive pre-admission living situations (p = 0.011), less restrictive discharge locations (p = 0.001), more independence in activities of daily living (p = 0.001) and less physiotherapy visits (p < 0.001). A correlation was found between the "6-clicks" and length of stay (r= -0.408, p = 0.001), but not between the "6-clicks" and age (r= -0.180, p = 0.528). To determine the inter-rater reliability, an additional 50 patients were assessed by pairs of physiotherapists who independently scored the patients. Intraclass Correlation Coefficients of 0.920 (95%CI: 0.828-0.964) were found. The Kappa Coefficients for the individual items ranged from 0.649 (walking stairs) to 0.841 (sit-to-stand). The Dutch "6-clicks" shows a good construct validity and moderate-to-excellent inter-rater reliability when used to assess the mobility of hospitalized patients. Implications for Rehabilitation Even though various measurement tools have been developed, it appears the majority of physiotherapists working in a hospital currently do not use these tools as a standard part of their care. The Activity Measure for Post-Acute Care "6-clicks" Basic Mobility is the only tool which is designed to be short, easy to use within usual care and has been validated in the entire hospital population. This study shows that the Dutch version of the Activity Measure for Post-Acute Care "6-clicks" Basic Mobility form is a valid, easy to use, quick tool to assess the basic mobility of Dutch hospitalized patients.

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.

Surviving critical illness: what is next? An expert consensus statement on physical rehabilitation after hospital discharge

BACKGROUND

The study objective was to obtain consensus on physical therapy (PT) in the rehabilitation of critical illness survivors after hospital discharge. Research questions were: what are PT goals, what are recommended measurement tools, and what constitutes an optimal PT intervention for survivors of critical illness?

METHODS

A Delphi consensus study was conducted. Panelists were included based on relevant fields of expertise, years of clinical experience, and publication record. A literature review determined five themes, forming the basis for Delphi round one, which was aimed at generating ideas. Statements were drafted and ranked on a 5-point Likert scale in two additional rounds with the objective to reach consensus. Results were expressed as median and semi-interquartile range, with the consensus threshold set at ≤0.5.

RESULTS

Ten internationally established researchers and clinicians participated in this Delphi panel, with a response rate of 80 %, 100 %, and 100 % across three rounds. Consensus was reached on 88.5 % of the statements, resulting in a framework for PT after hospital discharge. Essential handover information should include information on 15 parameters. A core set of outcomes should test exercise capacity, skeletal muscle strength, function in activities of daily living, mobility, quality of life, and pain. PT interventions should include functional exercises, circuit and endurance training, strengthening exercises for limb and respiratory muscles, education on recovery, and a nutritional component. Screening tools to identify impairments in other health domains and referral to specialists are proposed.

CONCLUSIONS

A consensus-based framework for optimal PT after hospital discharge is proposed. Future research should focus on feasibility testing of this framework, developing risk stratification tools and validating core outcome measures for ICU survivors.
