Investigating the safety of physical rehabilitation with critically ill patients receiving vasoactive drugs: An exploratory observational feasibility study

BACKGROUND

Physical rehabilitation of critically ill patients may improve physical outcomes; however, the relative benefits and risks with patients requiring vasoactive drugs is currently unknown. A feasibility study is needed to inform the design of a future trial required to address this issue.

METHODS

A two-phase exploratory observational feasibility study was carried out: A retrospective study to clarify the current practice of rehabilitation with patients receiving vasoactive drugs to inform future trial interventions and design.A prospective study exploring recruitment and outcome measurement. Intensive care patients receiving vasoactive drugs were recruited and asked about the acceptability of a future trial. The feasibility of using an adverse event tool was measured during rehabilitation. Patients were followed up after 60 days to describe the feasibility of measuring outcomes for a future trial.

RESULTS

Retrospective study (n = 78): Twenty-one percent of patients took part in physical rehabilitation whilst receiving vasoactive drugs. Of 321 days with vasoactive drugs administered, physical rehabilitation occurred on 27 days (8%). Prospective study (n = 40): Eighty-one percent of participants indicated acceptability of being recruited into a future trial (n = 37). Eighty-eight percent of clinicians found it acceptable to randomise patients into either early rehabilitation or standard care. The adverse event tool was implemented by researchers with 2% loss of information. Finally, a 100% follow-up rate at day 60 was achieved for mortality outcomes. Follow-up rates were 70% for the EQ-5D (5 level), 65% for the World Health Organisation's Disability Assessment Schedule 2.0 and RAND 36-item Health Survey 1.0 and 26% for the 6-minute walk test.

CONCLUSIONS

This study found a low frequency of physical rehabilitation occurring with intensive care patients receiving vasoactive drugs. A high proportion of clinicians and patients found a future RCT within this patient group acceptable. Mortality and patient-reported outcomes were the most feasible to measure.

Identification and quantification of physical activity in critically ill burn patients: A feasibility study

BACKGROUND

Physical activity is essential in burn care to counteract the effects of severe burns and inactivity during hospitalization. However, detailed knowledge of performed physical activities is lacking. This study evaluated the feasibility of a dual accelerometer-based method to assess type, frequency, and duration of physical activity in critically ill burn patients during hospitalization.

METHODS

A prospective observational study was conducted at the burn center of the Martini Hospital, Groningen, The Netherlands. Eligible were patients with a total body surface area (TBSA) burned of ≥ 15 % or an indication for intensive care. Patients wore two accelerometers, one on the chest and one on the diagonally opposite thigh. An algorithm converted accelerometer data into type, frequency, and duration of activities common for intensive care patients. An activity diary was used to assess non-wear time and its content, e.g., surgery.

RESULTS

Five patients (20-60 years, 13-31 % TBSA burned, LOS 30-65 days) were included. Per patient, 14-49 days (17,380-61,796 min) could be analyzed of which 7-14 % was non-wear time. During wear time, 86-95 % of activities could be identified and quantified. However, processing the data was labor-intensive.

CONCLUSION

The dual accelerometer-based method proved feasible for research purposes. For clinical application, further refinement of data processing is required.

Investigating Dose Level and Duration of Rehabilitation of Mechanically Ventilated Patients in the ICU

Background: The dose level and duration needed for early rehabilitation of mechanically ventilated patients in the ICU need to be characterized. Therefore, this study aimed to assess the association between mobilization level, rehabilitation time, and dose (defined as the mean mobilization quantification score [MQS]) during ICU admission and the end point walking independence at hospital discharge in subjects needing ICU admission. Methods: This prospective, multi-center, cohort study included 9 ICUs. Consecutive subjects admitted to the ICU between September 2022-March 2023 receiving mechanical ventilation for >48 h were included in the study. The mean MQS score, highest ICU mobility score (IMS) during the ICU stay, time to the first mobilization day, ICU rehabilitation time (minutes of each rehabilitation physical activity from start to finish), frequency/d, baseline characteristics, and walking independence at hospital discharge were assessed. Results: Among the 116 subjects, 64 did and 51 did not walk independently at hospital discharge, respectively. Multiple logistic regression analysis revealed that the mean MQS and time to first mobilization were significantly associated with walking independence at hospital discharge. We observed that mean MQS was better than IMS, rehabilitation time, frequency, and time to first mobilization predicted walking independence based on receiver operating characteristic (ROC) curve comparison. Comparison of the mean MQS with that on the first mobilization day revealed superior predicting power of the mean MQS. The ROC curve cutoff value for the mean MQS was 4.0. Conclusions: This study shows that in subjects mechanically ventilated for >48 h the dose of rehabilitation calculated using the mean MQS during ICU was a better predictor of walking independence at hospital discharge than intensity, duration, or frequency of the mobilization therapy. Mean MQS during ICU stay may be used to measure and titrate optimal mobilization therapy.

Experience in Rehabilitation Treatment for Patients Repeatedly Admitted to Intensive Care Units After Dual Graft Living-Donor Liver Transplantation: A Case Report

Living-donor liver transplantation (LDLT) has become a common procedure in Japan, allowing patients to maintain their activities of daily living (ADL) after surgery. However, complications, such as bile leakage and septic shock, often occur, necessitating intensive rehabilitation. This case report details the rehabilitation of a woman in her 60s who experienced peritonitis and recurrent septic shock after LDLT, with the goal of providing insights for future rehabilitation protocols. The patient had a preoperative Child-Pugh class C and Model for End-Stage Liver Disease score of 21. Preoperative rehabilitation included gait and muscle-strengthening exercises. After a 15-hour dual-graft LDLT, she experienced multiple postoperative complications, including bile leakage on day X+22, requiring resuturing and multiple intensive care unit (ICU) admissions. Rehabilitation was adjusted to suit her ICU condition, with exercises, such as range-of-motion and assisted walking, based on her ICU mobility score. After her final ICU discharge on day X+55, she continued rehabilitation in a general ward, progressing from wheelchair transfer to walking with a walker, which resulted in Barthel index improvement from 0 to 55 on day X+133. Despite improved ADL, she experienced muscle atrophy, particularly in the psoas muscle, due to ICU-acquired weakness and prolonged inactivity. This case highlights the importance of individualized rehabilitation approaches in patients with LDLT and associated complications. Given the lack of specific post-LDLT guidelines, particularly for patients with ICU-AW, this report highlights the need for objective indicators, such as heart rate control and muscle strength assessments, to guide rehabilitation. Traditional methods have proven effective in improving ADL; however, further strategies are needed to address muscle mass recovery. This case suggests that a tailored approach can improve patient outcomes and provide valuable insights into the development of LDLT-specific rehabilitation guidelines.

Leg Cycle Ergometry in Critically Ill Patients - An Updated Systematic Review and Meta-Analysis

BACKGROUND

Cycle ergometry is a rehabilitation strategy used in the intensive care unit (ICU) which may help mitigate post-ICU impairments. We aimed to systematically review and summarize evidence examining the efficacy and safety of cycle ergometry in the ICU.

METHODS

We included randomized controlled trials (RCTs) of critically ill adults with any diagnosis admitted to the ICU for >24 hours, comparing cycling interventions to control (no cycling). The primary outcome was physical function, using a hierarchical approach to standardize this outcome across trials. We performed random-effects meta-analyses and assessed the certainty of effect estimates using the Grading of Recommendations Assessment, Development, and Evaluation approach.

RESULTS

We included 33 RCTs that enrolled 3274 patients. Cycling may improve physical function at ICU discharge (12 RCTs, 1291 patients, standardized mean difference [SMD], 0.33 [95% confidence interval (CI), 0.05 to 0.62], low certainty) and posthospital discharge (8 RCTs, 865 patients, SMD, 0.23, [95% CI, 0.04 to 0.42], low certainty). Cycling may decrease ICU length of stay (29 RCTs, 2575 patients, mean difference [MD], 1.06 days fewer [95% CI, 0.33 to 1.80 days fewer], low certainty) and probably decreases hospital length of stay (22 RCTs, 2060 patients, MD, 1.48 days fewer [95% CI, 0.47 to 2.49 days fewer], moderate certainty). Cycling may have no effect on ICU mortality (17 RCTs, 2039 patients, risk ratio, 12 fewer deaths per 1000 [95% CI, 43 fewer to 23 more], low certainty). The pooled rate of adverse events in the intervention group was 1% (11 RCTs, 4623 sessions, [95% CI, 0 to 2%], low certainty) and in the comparison group, 2% (6 RCTs, 3365 sessions, [95% CI, 0 to 5%], low certainty).

CONCLUSIONS

In this meta-analysis, we found that cycling with critically ill patients may improve physical function at ICU discharge and after hospital discharge, may reduce ICU length of stay, and probably reduces hospital length of stay, with no effect on other outcomes including mortality. We observed low to very low certainty of evidence for all but one outcome of interest. Adverse events were uncommon. (PROSPERO number, CRD 42018092132.).

Association Between Verbal Communication With Families and Delirium in Mechanically Ventilated Patients: A Retrospective Study

Introduction Delirium in the intensive care unit (ICU) significantly impacts patient outcomes. While family involvement may help prevent delirium in ICU patients, its effect during mechanical ventilation remains unclear. This study investigated the association between verbal communication during family visits and early post-extubation delirium in mechanically ventilated ICU patients. Materials and methods This retrospective, analytical observational study used data from the hospital's standard electronic health record (EHR) system, which includes routine medical and nursing documentation. We conducted this study in a 10-bed emergency ICU at an academic hospital in rural Japan from April 1, 2019, to December 31, 2020. We included patients aged ≥18 years who received invasive positive pressure ventilation for >48 hours. We excluded patients who were discharged while intubated, required a tracheostomy, or were unable to be assessed using the intensive care delirium screening checklist (ICDSC). The primary outcome was the maximum ICDSC score within 24 hours post-extubation. We conducted multiple regression analyses with ICDSC as the outcome. Results A total of 110 patients were analyzed. The mean age was 64.7 years (standard deviation ± 14.3), and 73 patients were male (66.4%). The median duration of intubation was five days (interquartile range (IQR), 4-8), and the median sequential organ failure assessment (SOFA) score was 8 (IQR, 6-11). The median ICDSC within 24 hours post-extubation was 3 (IQR, 2-5). Of the total 110 patients, 28 (25.5%) could communicate verbally. Patients who could communicate verbally had lower SOFA scores, longer duration of intubation, more frequent family visits, and higher intensive care mobility scale (IMS) scores during intubation. Neither single nor multiple regression showed a significant association between verbal communication and post-extubation ICDSC. Conclusions We did not find a statistically significant association between verbal communication during family visits with patients and ICDSC within 24 hours post-extubation. Potential confounders and variations in care practices may have influenced the results. Further studies are needed to address these limitations.

Association between changes in disease severity and physical function after surviving a critical illness: A multicentre retrospective observational study

BACKGROUND

Whilst disease severity can significantly impact functional outcomes, the ability to predict the scale of this impact has not been consistent.

AIM

We aimed to investigate whether changes in disease severity within the first 48 h of ICU admission are more strongly associated with physical dysfunction than a single-time assessment of disease severity at ICU admission.

METHODS

A multicentre retrospective study in seven tertiary ICUs in Japan, including all consecutive adult ICU patients (>48 h ICU stay) between September 2019 and February 2020. The primary outcome was physical function defined as the Barthel Index, which is an ordinal scale (0-100: larger indicates better function) to measure physical independence and performance. The association between Barthel Index score at hospital discharge and the Sequential Organ Failure Assessment (SOFA) scores, measured at ICU admission, the highest recorded score within 48 h of ICU admission, and the level of change between these two timepoints were investigated in multivariable analysis.

RESULTS

A total of 199 patients were included. Median SOFA score at ICU admission and the highest recorded score within the first 48 h were 6 (interquartile range: 5-10) and 8 (interquartile range: 6-11), respectively. A quarter of patients had a Barthel Index score of 60 or less at hospital discharge. The highest SOFA score within 48 h of ICU admission and the level of change in SOFA scores between ICU admission and the highest recorded score within 48 h were significantly associated with lower Barthel Index scores at hospital discharge. No significant association was identified with regard to Barthel Index scores and SOFA score at ICU admission. An increase in SOFA score of 1 or more within the first 48 h of ICU admission was the threshold to predict a Barthel Index score of 60 or less at hospital discharge. Larger changes in SOFA scores over the first 48 h of ICU admission were also significantly associated with smaller changes in Barthel Index scores from ICU discharge to hospital discharge.

CONCLUSIONS

The level of change in SOFA score between ICU admission and the highest recorded score within the first 48 h of ICU stay can more accurately predict the presence of physical dysfunction at hospital discharge than a single-time assessment of disease severity at ICU admission. The larger worsening in SOFA potentially indicates lower recovery after a critical illness.

Characterizing usual-care physical rehabilitation in Canadian intensive care unit patients: a secondary analysis of the Canadian multicentre Critical Care Cycling to Improve Lower Extremity Strength pilot randomized controlled trial

PURPOSE

Physical rehabilitation (PR) in the intensive care unit (ICU) may improve outcomes for survivors but clinical trial results have been discordant. We hypothesized that discordant results may reflect treatment heterogeneity received by "usual care" comparator groups in PR studies. Usual-care PR is typically underspecified, which is a barrier to comparing results across treatment studies. The primary objective of the present study was to describe the usual-care PR received by critically ill patients enrolled in the Canadian multicentre Critical Care Cycling to Improve Lower Extremity Strength (CYCLE) pilot randomized controlled trial (RCT) of PR. Other objectives were to help contextualize current research and provide data for international comparison.

METHODS

In this secondary analysis of the CYCLE pilot RCT, patients were randomized to in-bed cycling and usual-care PR or usual-care PR alone. Physiotherapists documented usual-care PR including therapy received, type of activity, duration, adverse events and consequences, reasons for no PR, and concurrent relevant medical interventions. We characterized usual care using descriptive statistics at the cohort and patient levels.

RESULTS

Across seven Canadian centres, 30 patients were randomized to usual-care PR. The median [interquartile range (IQR)] ICU stay was 10 [9-24] days and patients received PR on a median [IQR] of 5 [3-9] days for 23 [17-30] min per day. Eighteen patients (60%) stood, marched, or walked during usual care. Transient adverse events occurred in three patients on 1.5% (3/198) of days and none prompted session termination.

CONCLUSIONS

In the usual-care arm of the CYCLE pilot RCT, PR was delivered on half of ICU days and over half of patients stood, marched, or walked. Adverse events during usual-care PR were uncommon.

Neuromuscular Electrical Stimulation Under Deep Sedation Reduces the Incidence of ICU-Acquired Weakness in Critically Ill Patients With COVID-19 With Acute Respiratory Distress Syndrome

BACKGROUND

The COVID-19 pandemic has led to an unprecedented increase in cases of acute respiratory distress syndrome (ARDS). In such cases, deep sedation using sedatives and muscle relaxants is commonly used to prevent patient self-inflicted lung injury during the early phase. However, such sedation limits the ability to perform early rehabilitation, leading to ICU-acquired muscle weakness (ICU-AW) and a worse prognosis.

SUBJECTS

This study aimed to clarify the preventive effect of neuromuscular electrical stimulation (NMES) during deep sedation on ICU-AW and physical function at discharge in critically ill patients with COVID-19 with ARDS.

METHODS

A retrospective, single-center study was conducted on patients admitted to the ICU or advanced critical care center with severe COVID-19 with ARDS between March 1, 2020, and March 31, 2022. Patients who were managed with the Richmond Agitation-Sedation Scale between -4 and -5 for at least three days were included. Patients in the NMES group received NMES within two days of deep sedation, whereas those in the non-NMES group did not. The primary endpoint was the incidence of ICU-AW at discharge from the ICU, and the secondary endpoints included physical activity levels, skeletal muscle mass index, time to active mobilization, and Barthel index (BI) at discharge. Statistical analyses included Pearson's chi-squared test, Fisher's exact test, and multiple logistic and linear regression analyses.

RESULTS

Of the 129 patients, 68 (54 males and 14 females) were included after applying the exclusion criteria, with 38 in the NMES group and 30 in the non-NMES group. The incidence of ICU-AW was significantly lower in the NMES group (28.95% vs. 56.67%, p = 0.0211). NMES implementation (OR: 0.20, p = 0.03), ventilator weaning (OR: 0.10, p = 0.01), and duration of deep sedation (OR: 0.81, p < 0.01) were significant predictors of ICU-AW. Higher ICU Mobility Scale scores and shorter time to active mobilization were associated with a higher BI at discharge.

CONCLUSIONS

Early rehabilitation using NMES during deep sedation may prevent ICU-AW in critically ill patients with COVID-19 with ARDS. NMES is associated with a reduced risk of ICU-AW and improved functional independence at discharge. This procedure can be safely performed in sedated patients and may help prevent ICU-AW, supporting early mobilization strategies in ARDS rehabilitation.

Utilization of the pericapsular nerve group block in preoperative rehabilitation of patients with femoral neck fractures -a case series

BACKGROUND

Elderly patients with femoral neck fractures, particularly those with severe comorbidities or living in regions with limited medical resources, may experience delays in surgical treatment. Although the benefits of preoperative rehabilitation (prehabilitation) in hip arthroplasty have been reported, pain management remains a challenge. The pericapsular nerve group (PENG) block, known for its exceptional analgesic effect and motor function preservation, may be a promising intervention during prehabilitation in these patients.

CASE

We enrolled ten patients with Garden classification 3-4 femoral neck fractures scheduled for hip arthroplasty. After receiving a PENG block with 20 ml of 0.375% ropivacaine, all patients underwent initial prehabilitation sessions comprising 9 mobility levels, ranging from bed-sitting to walking. One patient was excluded due to experiencing high blood pressure during prehabilitation. Six of the nine remaining patients (66.7%) were successfully transferred from bed to wheelchair.

CONCLUSIONS

The PENG block enhanced prehabilitation for patients with femoral neck fractures undergoing hip arthroplasty.

Evaluating optimal rehabilitation strategies in ICU: study protocol for a multicentre cohort study to assess Physical Activity dosing, Muscle mass, and physICal outcomeS (IPAMICS study)

BACKGROUND

Many patients who get discharged from the intensive care unit experience physical dysfunction that persists even after discharge. Physical dysfunction is associated with skeletal muscle atrophy and accompanying intensive care unit-acquired weakness in the early stages of intensive care unit admission, and early diagnosis and prevention with early mobilization are crucial. However, the amount of physical activity required for early mobilization remains controversial in critically ill patients. This study aims to reveal the optimal mobilization quantification score dose associated with physical dysfunction after hospital discharge.

METHODS

This is a multicenter prospective cohort study planned in 22 facilities; all consecutive patients admitted to the participating facilities between June 2024 and May 2025 will be included. Adult patients on ventilator management for at least 2 days and who will consent to this study will be included. Patients' mobility level and duration will be documented by the mobilization quantification score during their intensive care unit stay, and physical dysfunction will be assessed using muscle mass changes from day one to seven with ultrasonography and the Short-Form 12 Health Survey at 3 months after hospital discharge. The primary outcome is physical dysfunction at 3 months.

RESULTS AND CONCLUSION

Mobilization quantification score dose and muscle mass evaluation with ultrasonography will enable the quantification of the early mobilization intervention. This study will lay the foundation for future randomised studies.

Characteristics of longitudinal changes in quality of life and associated factors in patients post cardiac and thoracic aortic surgery: insights from a prospective cohort study

BACKGROUND

Although quality of life (QOL) is an outcome of postoperative cardiac rehabilitation (CR), its course and related factors from postoperative hospitalization to the post-discharge period have not been adequately investigated. Additionally, the EuroQol-5Dimension-5Level (EQ-5D-5L) index score has not been characterized over the same period. We aimed to characterize QOL changes assessed by the EQ-5D-5L, over the period from hospitalization to 1 year post-discharge, in patients post-cardiac and thoracic aortic surgery, and investigate the factors associated with these temporal changes.

METHODOLOGY

This prospective, single-center study included 117 patients who underwent open cardiovascular surgery (median age, 72 years; men, 69%). Patients were assessed for QOL status when transferred to the general ward; at discharge; and at 6 and 12 months after discharge, using the EQ-5D-5L index score and a generalized linear mixed model with random intercepts. Patients were classified into two groups based on score changes post-discharge. Logistic regression analysis evaluated factors associated with QOL decrease post-discharge.

RESULTS

The EQ-5D-5L index score significantly increased over time, except between 6 and 12 months post-discharge; "Common activities" was the most common dimension showing score improvement. In 25 patients (21%), the EQ-5D-5L index scores were lower after discharge compared to their scores at discharge. In the logistic regression analysis, Barthel Index pre-admission, preoperative hemoglobin level, and Mini-Mental State Examination-Japanese scores pre-discharge were significantly associated with QOL decline after adjusting for the European System for Cardiac Operative Risk Evaluation II score.

CONCLUSIONS

Most patients post-cardiac or thoracic aortic surgery experienced improved QOL from postoperative hospital stay to 1 year post-discharge. However, in patients with pre-operative basic activities of daily living, hemoglobin and post-operative cognitive decline may require ongoing comprehensive CR because of reduced QOL. Given the potential selection bias introduced by the relatively small sample size in this study, future research involving larger populations is necessary.

Association Between Early Mobilization and Postoperative Pneumonia Following Robot-assisted Minimally Invasive Esophagectomy in Patients with Thoracic Esophageal Squamous Cell Carcinoma

OBJECTIVE

The objective of this study was to confirm that early mobilization (EM) could reduce pneumonia in patients undergoing robot-assisted minimally invasive esophagectomy (RAMIE) for thoracic esophageal squamous cell carcinoma (TESCC).

METHODS

Postoperative pneumonia was defined as physician-diagnosed pneumonia using the Esophagectomy Complications Consensus Group definition of pneumonia with a Clavien-Dindo classification grade II-V on postoperative day (POD) 3-5. EM was defined as achieving an ICU Mobility Scale (IMS) ≥7 by POD 2. Patients were divided into EM (n = 36) and non-EM (n = 35) groups. Barriers to EM included pain, orthostatic intolerance (OI), and orthostatic hypotension.

RESULTS

The overall incidence of postoperative pneumonia was 12.7%, with a significant difference between the EM (2.8%) and non-EM (22.9%) groups (P = 0.014). The odds ratio was 0.098 in the EM group compared to the non-EM group. A significant difference was found between the two groups in terms of the barriers to EM at POD 2 only for OI, with a higher incidence in the non-EM group. Multivariate logistic regression analysis showed that patients with OI were more likely to be unable to achieve EM than those without OI (odds ratio, 7.030; P = 0.006).

CONCLUSION

EM within POD 2 may reduce the incidence of postoperative pneumonia in patients undergoing RAMIE for TESCC. Furthermore, it was suggested that OI can have a negative impact on the EM after RAMIE.

Study of the intensive care unit activity scale in the early rehabilitation of patients after direct cardiac surgery

BACKGROUND

Direct cardiac surgery often necessitates intensive post-operative care, and the intensive care unit (ICU) activity scale represents a crucial metric in assessing and guiding early rehabilitation efforts to enhance patient recovery.

AIM

To clarify the clinical application value of the ICU activity scale in the early recovery of patients after cardiac surgery.

METHODS

One hundred and twenty patients who underwent cardiac surgery between September 2020 and October 2021 were selected and divided into two groups using the random number table method. The observation group was rated using the ICU activity scale and the corresponding graded rehabilitation interventions were conducted based on the ICU activity scale. The control group was assessed in accordance with the routine rehabilitation activities, and the postoperative rehabilitation indexes of the patients in both groups were compared (time of tracheal intubation, time of ICU admission, occurrence of complications, and activity scores before ICU transfer). The two groups were compared according to postoperative rehabilitation indicators (time of tracheal intubation, length of ICU stay, and occurrence of complications) and activity scores before ICU transfer.

RESULTS

In the observation group, tracheal intubation time lasted for 18.30 ± 3.28 h and ICU admission time was 4.04 ± 0.83 d, which were significantly shorter than the control group (t-values: 2.97 and 2.038, respectively, P < 0.05). The observation group also had a significantly lower number of complications and adverse events compared to the control group (P < 0.05). Before ICU transfer, the observation group (6.7%) had few complications and adverse events than the control group (30.0 %), and this difference was statistically significant (P < 0.05). Additionally, the activity score was significantly higher in the observation (26.89 ± 0.97) compared to the control groups (22.63 ± 1.12 points) (t-value; -17.83, P < 0.05).

CONCLUSION

Implementation of early goal-directed activities in patients who underwent cardiac surgery using the ICU activity scale can promote the recovery of cardiac function.

Rehabilitation and Physiotherapy Action Strategy for an Acute Case of Lateral Medullary Syndrome: A Case Report

Lateral medullary syndrome (LMS) may result from a failure in either the vertebral artery or the posterior inferior cerebellar artery. Stroke is the most common cause of LMS. To achieve bronchial hygiene and improve the patient's condition, chest physiotherapy was initiated due to his confined condition during the acute stage. As a result, a four-week physiotherapy program was established and administered twice daily to the patient, with noticeable results. A physical examination revealed that the patient exhibited tachycardia, dyspnea, intracranial nerve palsies on the left side, thermoanesthesia on the right, horizontal nystagmus, and ptosis and miosis in the left eye associated with Horner syndrome. After receiving appropriate conservative care, the patient was discharged from the hospital with the fewest possible disabilities.

Nutrition delivery and the relationship with changes in muscle mass in adult patients receiving extracorporeal membrane oxygenation: A retrospective observational study

BACKGROUND

Adverse changes in muscle health (size and quality) are common in patients receiving extracorporeal membrane oxygenation (ECMO). Nutrition delivery may attenuate such changes, yet the relationship with muscle health remains poorly understood. This study explored the association between energy and protein delivery and changes in muscle health measured using ultrasound from baseline to day 10 and 20 in patients receiving ECMO.

METHODS

A secondary analysis of data from a prospective study quantifying changes in muscle health using ultrasound in adults receiving ECMO was completed. Patients were eligible for inclusion if they were prescribed artificial nutrition within 3 days of enrolment and had >1 ultrasound measurement. The primary outcome was the association between protein delivery (grams delivered and percentage of targets received) and change in rectus femoris cross-sectional area (RF-CSA) till day 20. Secondary outcomes were the association between energy and protein delivery and change in RF-CSA till day 10, RF-echogenicity, and quadriceps muscle layer thickness to day 10 and 20. Associations were assessed using Spearman's rank correlation.

RESULTS

Twenty-three patients (age: 48 [standard deviation {SD}: 14], 44% male) were included. Mean energy and protein delivery were 1633 kcal (SD: 374 kcal) and 70 g (SD: 17 g) equating to 79% (SD: 19%) of energy and 73% (SD: 17%) of protein targets. No association was observed between protein delivery (r = 0.167; p = 0.495) or the percentage of targets received (r = 0.096; p = 0.694) and change in RF-CSA till day 20. No other significant associations were found between energy or protein delivery and change in RF-CSA, echogenicity, or quadriceps muscle layer thickness at any time point.

CONCLUSIONS

This exploratory study observed no association between nutrition delivery and changes in muscle health measured using ultrasound in patients receiving ECMO. Larger prospective studies are required to investigate the association between nutrition delivery and changes in muscle health in patients receiving ECMO.

Outcome Measures to Evaluate Functional Recovery in Survivors of Respiratory Failure: A Scoping Review

BACKGROUND

Respiratory failure is a life-threatening condition affecting millions of individuals in the United States annually. Survivors experience persistent functional impairments, decreased quality of life, and cognitive impairments. However, no established standard exists for measuring functional recovery among survivors of respiratory failure.

RESEARCH QUESTION

What outcomes are being used to measure and characterize functional recovery among survivors of respiratory failure?

STUDY DESIGN AND METHODS

In this scoping review, we developed a review protocol following International Prospective Register of Systematic Reviews (PROSPERO) guidelines. Two independent reviewers assessed titles and abstracts, followed by full-text review. Articles were included if study participants were aged 18 years or older, survived a hospitalization for acute respiratory failure, and received invasive mechanical ventilation as an intervention; identified function or functional recovery after respiratory failure as a study outcome; were peer-reviewed; and used any type of quantitative study design.

RESULTS

We reviewed 5,873 abstracts and identified 56 eligible articles. Among these articles, 28 distinct measures were used to assess functional recovery among survivors, including both performance-based measures (n = 8) and self-reported and proxy-reported measures (n = 20). Before 2019, 12 of the 28 distinct outcome measures (43%) were used, whereas 25 distinct measures (89%) were used from 2019 through 2024. The 6-min walk test appeared most frequently (46%) across the studies, and only 34 of 56 studies measured outcomes ≥ 6 months after discharge or study enrollment.

INTERPRETATION

Heterogeneity exists in how functional recovery is measured among survivors of respiratory failure, which highlights a need to establish a gold standard to ensure effective and consistent measurement. CHEST Critical Care 2024; 2(3):100084.

Behavioral Assessment With the Coma Recovery Scale-Revised Is Safe and Feasible in Critically Ill Patients With Disorders of Consciousness

OBJECTIVES

Accurate classification of disorders of consciousness (DoC) is key in developing rehabilitation plans after brain injury. The Coma Recovery Scale-Revised (CRS-R) is a sensitive measure of consciousness validated in the rehabilitation phase of care. We tested the feasibility, safety, and impact of CRS-R-guided rehabilitation in the ICU for patients with DoC after acute hemorrhagic stroke.

DESIGN

Retrospective cohort study.

SETTING

This single-center study was conducted in the neurocritical care unit at the University of Maryland Medical Center.

PATIENTS

We analyzed records from consecutive patients with subarachnoid hemorrhage (SAH) or intracerebral hemorrhage (ICH), who underwent serial CRS-R assessments during ICU admission from April 1, 2018, to December 31, 2021, where CRS-R less than 8 is vegetative state/unresponsive wakefulness syndrome (VS/UWS); CRS-R greater than or equal to 8 is a minimally conscious state (MCS).

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Outcomes included adverse events during CRS-R evaluations and associations between CRS-R and discharge disposition, therapy-based function, and mobility. We examined the utility of CRS-R compared with other therapist clinical assessment tools in predicting discharge disposition. Seventy-six patients (22 SAH, 54 ICH, median age = 59, 50% female) underwent 276 CRS-R sessions without adverse events. Discharge to acute rehabilitation occurred in 4.4% versus 41.9% of patients with a final CRS-R less than 8 and CRS-R greater than or equal to 8, respectively (odds ratio [OR] 13.4; 95% CI, 2.7-66.1; p < 0.001). Patients with MCS on final CRS-R completed more therapy sessions during hospitalization and had improved mobility and functional performance. Compared with other therapy assessment tools, the CRS-R had the best performance in predicting discharge disposition (area under the curve: 0.83; 95% CI, 0.72-0.94; p < 0.0001).

CONCLUSIONS

Early neurorehabilitation guided by CRS-R appears to be feasible and safe in the ICU following hemorrhagic stroke complicated by DoC and may enhance access to inpatient rehabilitation, with the potential for lasting benefit on recovery. Further research is needed to assess generalizability and understand the impact on long-term outcomes.

Frailty, Outcomes, Recovery and Care Steps of Critically Ill Patients (FORECAST): a prospective, multi-centre, cohort study

PURPOSE

Frailty is common in critically ill patients but the timing and optimal method of frailty ascertainment, trajectory and relationship with care processes remain uncertain. We sought to elucidate the trajectory and care processes of frailty in critically ill patients as measured by the Clinical Frailty Scale (CFS) and Frailty Index (FI).

METHODS

This is a multi-centre prospective cohort study enrolling patients ≥ 50 years old receiving life support > 24 h. Frailty severity was assessed with a CFS, and a FI based on the elements of a comprehensive geriatric assessment (CGA) at intensive care unit (ICU) admission, hospital discharge and 6 months. For the primary outcome of frailty prevalence, it was a priori dichotomously defined as a CFS ≥ 5 or FI ≥ 0.2. Processes of care, adverse events were collected during ICU and ward stays while outcomes were determined for ICU, hospital, and 6 months.

RESULTS

In 687 patients, whose age (mean ± standard deviation) was 68.8 ± 9.2 years, frailty prevalence was higher when measured with the FI (CFS, FI %): ICU admission (29.8, 44.8), hospital discharge (54.6, 67.9), 6 months (34.1, 42.6). Compared to ICU admission, aggregate frailty severity increased to hospital discharge but improved by 6 months; individually, CFS and FI were higher in 45.3% and 50.6% patients, respectively at 6 months. Compared to hospital discharge, 18.7% (CFS) and 20% (FI) were higher at 6 months. Mortality was higher in frail patients. Processes of care and adverse events were similar except for worse ICU/ward mobility and more frequent delirium in frail patients.

CONCLUSIONS

Frailty severity was dynamic, can be measured during recovery from critical illness using the CFS and FI which were both associated with worse outcomes. Although the CFS is a global measure, a CGA FI based may have advantages of being able to measure frailty levels, identify deficits, and potential targets for intervention.

Early In-Bed Cycle Ergometry in Mechanically Ventilated Patients

BACKGROUND

Critical illness requiring invasive mechanical ventilation can precipitate important functional disability, contributing to multidimensional morbidity following admission to an intensive care unit (ICU). Early in-bed cycle ergometry added to usual physiotherapy may mitigate ICU-acquired physical function impairment.

METHODS

We randomly assigned 360 adult ICU patients undergoing invasive mechanical ventilation to receive 30 minutes of early in-bed Cycling + Usual physiotherapy (n=178) or Usual physiotherapy alone (n=182). The primary outcome was the Physical Function ICU Test-scored (PFIT-s) at 3 days after discharge from the ICU (the score ranges from 0 to 10, with higher scores indicating better function).

RESULTS

Cycling began within a median (interquartile range) of 2 (1 to 3) days of starting mechanical ventilation; patients received 3 (2 to 5) cycling sessions for a mean (±standard deviation) of 27.2 ± 6.6 minutes. In both groups, patients started Usual physiotherapy within 2 (2 to 4) days of mechanical ventilation and received 4 (2 to 7) Usual physiotherapy sessions. The duration of Usual physiotherapy was 23.7 ± 15.1 minutes in the Cycling + Usual physiotherapy group and 29.1 ± 13.2 minutes in the Usual physiotherapy group. No serious adverse events occurred in either group. Among survivors, the PFIT-s at 3 days after discharge from the ICU was 7.7 ± 1.7 in the Cycling + Usual physiotherapy group and 7.5 ± 1.7 in the Usual physiotherapy group (absolute difference, 0.23 points; 95% confidence interval, -0.19 to 0.65; P=0.29).

CONCLUSIONS

Among adults receiving mechanical ventilation in the ICU, adding early in-bed Cycling to usual physiotherapy did not improve physical function at 3 days after discharge from the ICU compared with Usual physiotherapy alone. Cycling did not cause any serious adverse events.

Reliability and validity of the Chinese version of the functional status score for the ICU (FSS-ICU) after translation and cross-cultural adaptation

PURPOSE

The Functional Status Score for the Intensive Care Unit (FSS-ICU) is designed to assess the physical functional status of patients in ICU settings. This study aimed to translate and culturally adapt the FSS-ICU for the Chinese context and to evaluate its reliability and validity.

METHODS

Following Beaton's translation model, the original FSS-ICU was subjected to forward translation, back-translation, and synthesis. After cultural adaptation and preliminary testing, the Chinese version of the FSS-ICU was established, and then two rehabilitation therapists assessed the functional status of 51 ICU patients using this scale, evaluating its reliability and validity.

RESULTS

The Chinese version of the FSS-ICU exhibits excellent internal consistency with a Cronbach's alpha coefficient of 0.934. The inter-rater and intra-rater correlation coefficients are 0.995 and 0.997, respectively. Both item-level and scale-level content validity indices are 1.00. The FSS-ICU demonstrates good convergent validity with other physical function assessment tools (Medical Research Council Sum-Score, grip strength, the Intensive Care Unit Mobility Scale), with |rs| values all above 0.5, and satisfactory discriminant validity with non-physical function assessment indicators (body mass index, blood glucose), with |rs| values all below 0.2. Additionally, it demonstrated no ceiling or floor effects.

CONCLUSION

The Chinese FSS-ICU, demonstrating strong reliability and validity, can serve as an effective assessment tool for physical function in ICU patients.

Effects of Vibration Therapy on the Physical Function of Critically Ill Adults Trial: A Randomized Controlled Trial

OBJECTIVES

Vibration therapy uses vibration to rehabilitate physical functions. Recently, it has been demonstrated to be safe for critically ill patients. However, its effects on physical functions are unclear.

DESIGN

Randomized controlled trial.

SETTING

A single-center, ICU.

PATIENTS

Patients were randomly assigned to either vibration therapy coupled with protocolized mobilization or protocolized mobilization alone. We included patients who could sit at the edge of the bed or in a wheelchair during their ICU stay. The exclusion criteria were based on the early mobilization inhibition criteria.

INTERVENTIONS

The primary outcome was the Functional Status Score for the ICU (FSS-ICU) at ICU discharge. Secondary outcomes were the Medical Research Council score, ICU-acquired weakness, delirium, ICU Mobility Scale (IMS), and ventilator- and ICU-free days. For safety assessment, vital signs were monitored during the intervention.

MEASUREMENTS AND MAIN RESULTS

Among 180 patients, 86 and 90 patients remained in the vibration therapy and control groups, respectively. The mean age was 69 ± 13 vs. 67 ± 16 years in the vibration therapy and control groups, and the Acute Physiology and Chronic Health Evaluation (APACHE) II score was 19 (14-25) vs. 18 (13-23). The total FSS-ICU at ICU discharge was 24 (18-27) and 21 (17-26) in the intervention and control groups, respectively ( p = 0.09), and the supine-to-sit ability significantly improved in the intervention group ( p < 0.01). The secondary outcomes were not significantly different. Vital signs remained stable during vibration therapy. In the predefined subgroup analysis, FSS-ICU improved in the population with a higher body mass index (≥ 23 kg/m 2 ), lower APACHE II scores (< 19), and higher IMS scores (≥ 6).

CONCLUSIONS

Vibration therapy did not improve the total FSS-ICU. However, the supine-to-sit ability in the FSS-ICU improved without any adverse event.

Early Mobilization Using a Mobile Patient Lift in the ICU: A Randomized Controlled Trial

OBJECTIVES

To ascertain whether a mobile patient lift facilitates early mobilization in ventilated ICU patients.

DESIGN

A single-center, open-label, randomized controlled trial.

SETTING

An academic ICU in Tokyo.

PATIENTS

Eighty patients were admitted to ICU and expected ventilation for at least 48 hours.

INTERVENTIONS

In the intervention group, in addition to the rehabilitation protocol received by the control group, patients were assisted in sitting, standing, transfers, and walking using the mobile patient lift.

MEASUREMENTS AND MAIN RESULTS

The intervention group predominantly stood faster than the control group (1.0 vs. 3.0 d, p < 0.01). The Intervention group also had significantly higher Functional Status Score-ICU scores at ICU discharge. However, the Medical Research Council score and Barthel index at discharge, length of ICU stay, and number of ventilator-free days did not differ between the two groups.

CONCLUSIONS

The use of mobile patient lifts facilitates the earlier standing of patients on ventilators. This may contribute to patients improved physical function in the ICU.

Assessing the impact of early progressive mobilization on moderate-to-severe traumatic brain injury: a randomized controlled trial

INTRODUCTION

Traumatic brain injury (TBI) is a major cause of neurodisability worldwide, with notably high disability rates among moderately severe TBI cases. Extensive previous research emphasizes the critical need for early initiation of rehabilitation interventions for these cases. However, the optimal timing and methodology of early mobilization in TBI remain to be conclusively determined. Therefore, we explored the impact of early progressive mobilization (EPM) protocols on the functional outcomes of ICU-admitted patients with moderate to severe TBI.

METHODS

This randomized controlled trial was conducted at a trauma ICU of a medical center; 65 patients were randomly assigned to either the EPM group or the early progressive upright positioning (EPUP) group. The EPM group received early out-of-bed mobilization therapy within seven days after injury, while the EPUP group underwent early in-bed upright position rehabilitation. The primary outcome was the Perme ICU Mobility Score and secondary outcomes included Functional Independence Measure motor domain (FIM-motor) score, phase angle (PhA), skeletal muscle index (SMI), the length of stay in the intensive care unit (ICU), and duration of ventilation.

RESULTS

Among 65 randomized patients, 33 were assigned to EPM and 32 to EPUP group. The EPM group significantly outperformed the EPUP group in the Perme ICU Mobility and FIM-motor scores, with a notably shorter ICU stay by 5.9 days (p < 0.001) and ventilation duration by 6.7 days (p = 0.001). However, no significant differences were observed in PhAs.

CONCLUSION

The early progressive out-of-bed mobilization protocol can enhance mobility and functional outcomes and shorten ICU stay and ventilation duration of patients with moderate-to-severe TBI. Our study's results support further investigation of EPM through larger, randomized clinical trials. Clinical trial registration ClinicalTrials.gov NCT04810273 . Registered 13 March 2021.

A comprehensive physical functional assessment of survivors of critical care unit stay due to COVID-19

OBJECTIVE

To examine the physical function and respiratory muscle strength of patients - who recovered from critical COVID-19 - after intensive care unit discharge to the ward on Days one (D1) and seven (D7), and to investigate variables associated with functional impairment.

METHODS

This was a prospective cohort study of adult patients with COVID-19 who needed invasive mechanical ventilation, non-invasive ventilation or high-flow nasal cannula and were discharged from the intensive care unit to the ward. Participants were submitted to Medical Research Council sum-score, handgrip strength, maximal inspiratory pressure, maximal expiratory pressure, and short physical performance battery tests. Participants were grouped into two groups according to their need for invasive ventilation: the Invasive Mechanical Ventilation Group (IMV Group) and the Non-Invasive Mechanical Ventilation Group (Non-IMV Group).

RESULTS

Patients in the IMV Group (n = 31) were younger and had higher Sequential Organ Failure Assessment scores than those in the Non-IMV Group (n = 33). The short physical performance battery scores (range 0 - 12) on D1 and D7 were 6.1 ± 4.3 and 7.3 ± 3.8, respectively for the Non-Invasive Mechanical Ventilation Group, and 1.3 ± 2.5 and 2.6 ± 3.7, respectively for the IMV Group. The prevalence of intensive care unit-acquired weakness on D7 was 13% for the Non-IMV Group and 72% for the IMV Group. The maximal inspiratory pressure, maximal expiratory pressure, and handgrip strength increased on D7 in both groups, but the maximal expiratory pressure and handgrip strength were still weak. Only maximal inspiratory pressure was recovered (i.e., > 80% of the predicted value) in the Non-IMV Group. Female sex, and the need and duration of invasive mechanical were independently and negatively associated with the short physical performance battery score and handgrip strength.

CONCLUSION

Patients who recovered from critical COVID-19 and who received invasive mechanical ventilation presented greater disability than those who were not invasively ventilated. However, they both showed marginal functional improvement during early recovery, regardless of the need for invasive mechanical ventilation. This might highlight the severity of disability caused by SARS-CoV-2.

Photobiomodulation therapy (red/NIR LEDs) reduced the length of stay in intensive care unit and improved muscle function: A randomized, triple-blind, and sham-controlled trial

CONTEXT

Photobiomodulation therapy (PBMT) has been widely used to improve strength, fatigue resistance and increase muscle mass in healthy individuals. These effects could help critically ill patients admitted to intensive care units (ICUs) who show reduced mobility and muscle strength. ICU-acquired weakness lessens overall health and increases the patient's length of stay in the ICU.

OBJECTIVE

This study evaluated the effects of PBMT using low intensity light-emitting diodes (LEDs) on the mobility and muscle strength (functional capacity) and length of stay of patients admitted to hospital ICU.

METHODS

This randomized, triple-blind, sham-controlled trial was conducted in a hospital ICU. Sixty patients were randomly assigned to two equal groups: (a) PBMT and (b) Sham. PBMT was applied daily to patients until their discharge from the ICU, using a flexible neoprene array of 264 LEDs (120 at 635 nm, 1.2 mW each; 144 at 880 nm, 15 mW each) for 90s (207.36 Joules) at each site. Ten sites were located bilaterally on the thighs, legs, arms, and forearms ventrally and dorsally, 15 min totaling 2,073.6 Joules per session. Outcomes were length of stay (in h) until discharge from the ICU, muscle strength by the Medical Research Council (MRC) score and handgrip dynamometry (HGD), patient mobility by Intensive Care Unit Mobility Scale (IMS) and the Simplified Acute Physiology Score 3 (SAPS 3) for predicting mortality of patients admitted to the ICU.

RESULTS

PBMT reduced the average length of stay in the ICU by ~30% (p = 0.028); increased mobility (IMS: 255% vs. 110% p = 0.007), increased muscle strength (MRC: 12% vs. -9% p = 0.001) and HGD (34% vs. -13% p < 0.001), and the SAPS3 score was similar (p > 0.05).

CONCLUSION

The results suggest that daily PBMT can reduce the length of stay of ICU patients and increase muscle strength and mobility.

Robotic-Assisted In-Bed Mobilization in Ventilated ICU Patients With COVID-19: An Interventional, Randomized, Controlled Pilot Study (ROBEM II Study)

OBJECTIVES

The COVID-19 pandemic significantly impacted global healthcare systems, particularly in managing critically ill mechanically ventilated patients. This study aims to assess the feasibility of robotic-assisted mobilization in COVID-19 patients.

DESIGN

Randomized controlled pilot study.

SETTING

Four COVID-19 specialized ICUs at Charité-Universitätsmedizin Berlin (March 2021 to February 2022).

PATIENTS

Twenty critically ill COVID-19 patients expected to require greater than 24 hours of ventilation.

INTERVENTIONS

A 5-day intervention phase with bid robotic-assisted mobilization greater than or equal to 20 minutes and follow-up at day 180, compared with standard care.

MEASUREMENTS AND MAIN RESULTS

Intervention sessions were conducted in 98.9% according to protocol, with one session missing due to staff shortage. Primary outcome was the mobilization level measured with the ICU Mobility Scale (IMS) and Surgical ICU Optimal Mobilization Score (SOMS), assessed until day 5 or extubation. Safety events were recorded during mobilization. The median IMS and SOMS were 0 (0-0.16) and 1 (1-1.03) in the intervention group, and 0 (0-0.15) ( p = 0.77) and 0.8 (0.65-1.20) ( p = 0.08) in the standard care group, respectively. Significant secondary outcomes included average number of mobilization sessions (intervention: 8.5 [7.75-10] vs. standard care: 4.5 [3.5-5]; p = 0.001), total mobilization time (intervention: 232.5 min [187.25-266.5 min] vs. standard care: 147.5 min [107.5-167.5 min]; p = 0.011), and healthcare providers per session (intervention: 2 [2-2] vs. standard care: 1 [1-1.4]; p = 0.001) during intervention. Four safety events (hypertension and agitation, n = 2 each) in the intervention group and none in the standard care group were reported.

CONCLUSIONS

Robotic-assisted mobilization in mechanically ventilated COVID-19 patients appears to be safe and feasible.

Functional Dependence Prior to ICU Admission is Associated with Worse Clinical and Functional Outcomes in Individuals with COVID-19: A Prospective Observational Study

Objectives: To determine whether low functional capacity (FC) prior to intensive care unit (ICU) admission due to coronavirus disease 2019 (COVID-19) might be associated with worse clinical outcomes. To monitor FC until discharge from the ICU. To identify associations between physical outcomes and decreased FC at discharge from the ICU. Design: Prospective observational study conducted from March to August 2021. Setting: ICU for adult patients with COVID-19. Participants: Adults (≥18 years) with COVID-19. Interventions: Not applicable. Main outcome measures: Clinical and demographic data were obtained from medical records. At ICU admission, evaluation was made of FC using the Barthel index (BI), and of the level of mobility using the ICU mobility scale. At ICU discharge, FC and mobility level were reassessed, and muscle strength was measured using the Medical Research Council (MRC) scale and the handgrip test. Results: The study was performed with 108 individuals. At the initial assessment, 73.1% of the patients were functionally independent. Length of hospital stay (odds ratio [OR]  =  1.05; 95%confidence interval [CI]  =  1.00-1.10) and death (OR  =  5.27; 95%CI  =  1.37-20.28) were related to functional status prior to ICU admission. Between ICU admission and discharge, the BI evaluation indicated a functional decline of 22.5 points. Low mobility level (P  =  .003) and low muscle strength assessed by the MRC scale (P < .001), measured at ICU discharge, were associated with a greater decrease of FC during the ICU stay. Conclusions: Patients with COVID-19 who were functionally dependent prior to ICU admission presented worse clinical outcomes, with low functional status being associated with longer hospitalization and higher mortality. However, irrespective of the initial functionality status, the surviving individuals suffered from functional decline at ICU discharge. Greater functional decline during the ICU stay was associated with lower muscle strength and lower mobility level at ICU discharge.

Association of Psoas Muscle Mass at Intensive Care Unit Admission With Physical Function and Post-discharge Destination in Survivors of Critical Illness

OBJECTIVE

Survivors of critical illness may have physical impairments, known as post-intensive care syndrome (PICS). Early screening for the risk of PICS is recommended to prevent PICS. Skeletal muscle mass is a clinically important indicator associated with various outcomes. This study aimed to examine the association of psoas muscle mass at intensive care unit (ICU) admission with the destination and physical function at hospital discharge.

METHODS

In this single-center retrospective cohort study, we reviewed the medical records of adult patients who had required emergency ICU admission and who had been intubated and mechanically ventilated. Psoas major muscle was measured as an indicator of skeletal muscle mass from abdominal computed tomography images at ICU admission. Physical function was assessed using the functional status score for the ICU and ICU mobility scale at hospital discharge. Multinomial logistic and multivariable linear regression were used to analyze the associations of the psoas muscle mass with the discharge destination and physical function at discharge.

RESULTS

We enrolled 124 patients (79 men and 45 women) with a median (interquartile range) age of 72.0 (62.0-80.0) years; 39 (31.5%) were discharged to home, 50 (40.3%) were transferred to rehabilitation wards, and 35 (28.2%) were transferred to long-term care settings. The psoas muscle area and volume were 16.9 (11.3-20.6) cm2 and 228.3 (180.2-282.0) cm3 in home discharge patients, 17.5 (11.5-21.5) cm2 and 248.4 (162.0-311.4) cm3 in rehabilitation ward patients, and 15.9 (10.3-19.5) cm2 and 184.0 (137.0-251.1) cm3 in long-term care patients. The areas and volumes of the psoas muscle were not significantly different in the three groups. Furthermore, psoas muscle mass was not significantly associated with the discharge destination and physical function.

CONCLUSIONS

Discharge destination and physical function at hospital discharge were not significantly associated with psoas muscle mass at ICU admission.

Rehabilitation for adult patients undergoing extracorporeal membrane oxygenation

BACKGROUND AND PURPOSE

Current information on the latest rehabilitative practices is limited, with previous reviews only covering data up to October 2021, and some considering only patients on awake ECMO or with COVID-19. This review aims to present a concise overview of the latest findings on rehabilitation and highlight emerging trends for patients undergoing ECMO support.

METHODS

This integrative review was conducted by searching the National Library of Medicine - PubMed database. Two different search strings "extracorporeal membrane oxygenation" AND "rehabilitation" and "extracorporeal membrane oxygenation" AND "physiotherapy" were used to search the published literature. Articles that did not describe rehabilitation techniques, editorials, conference proceedings, letters to editor, reviews and research protocols were excluded. Studies conducted on pediatric populations were also excluded. The search process was completed in December 2023.

RESULTS

Thirteen articles were included in the final analysis. Eight hundred and thirty-nine patients aged between 27 and 63 years were included; 428 were men (51%). In 31% of the included studies, patients had COVID-19; nevertheless, rehabilitative activities did not differ from non-COVID-19 patients. In most studies, rehabilitation commenced within the first 48-96 h and consisted of progressive exercise and out-of-bed activities such as sitting, standing and walking.

CONCLUSION

Current practice focuses on rehabilitative protocols that incorporate exercise routines with progressive intensity, greater emphasis on out-of-bed activities, and a multidisciplinary approach to patient mobilization.

Mobilisation during mechanical ventilation: A qualitative study exploring the practice of conscious patients, nurses and physiotherapists in intensive care unit

AIM

To explore the practice of mobilisation of conscious and mechanically ventilated patients and the interaction between patients, nurses and physiotherapists.

BACKGROUND

Long-term consequences of critical illness can be reduced by mobilisation starting in Intensive Care Units, but implementation in clinical practice is presently sparse.

DESIGN

A qualitative study with a phenomenological-hermeneutic approach.

METHODS

Participant observations in three Intensive Care Units involved twelve conscious mechanically ventilated patients, thirty-one nurses and four physiotherapists. Additionally seven semi-structured patient interviews, respectively at the ward and after discharge and two focus group interviews with healthcare professionals were conducted. The data analysis was inspired by Ricoeur's interpretation theory. The study adhered to the COREQ checklist.

FINDINGS

Healthcare professionals performed a balance of support and guidance to promote mobilisation practice. The complexity of ICU mobilisation required a flexible mobility plan. Furthermore, interaction with feedback and humour was found to be 'a leverage' for patient's motivation to partake in mobilisation. The practice of mobilisation found patients striving to cope and healthcare professionals promoting a 'balanced standing by' and negotiating the flexible mobility plan to support mobilisation.

CONCLUSION

The study revealed a need to clarify interprofessional communication to align expectations towards mobilisation of conscious and mechanically ventilated patients.

RELEVANCE TO CLINICAL PRACTICE

The study demonstrated the important role of healthcare professionals to perform a stepwise and 'balanced standing by' in adequately supporting and challenging the mobilisation of mechanically ventilated patients. Furthermore, a synergy can arise when nurses and physiotherapists use supplementary feedback and humour, and cooperate based on a flexible situation-specific mobility plan in intensive care.

Feasibility and Inter-rater Reliability of the Japanese Version of the Intensive Care Unit Mobility Scale

Purpose The purpose of this study was to verify the feasibility and inter-rater reliability of the Japanese version of the Intensive Care Unit Mobility Scale (IMS). Methods A prospective observational study was conducted at two intensive care units (ICUs) in Japan. The feasibility of the Japanese version of the IMS was assessed by 25 ICU staff (12 physical therapists and 13 nurses) using a 10-item questionnaire. Inter-rater reliability was assessed by two experienced physical therapists and two experienced nurses working with 100 ICU patients using the Japanese version of the IMS. Results In the questionnaire survey assessing feasibility, a high agreement rate was shown in 8 out of the 10 questions. All respondents could complete the IMS evaluation, and most respondents were able to complete the scoring of the IMS in a short time. The inter-rater reliability of the Japanese version of the IMS on the first day of physical therapy for ICU patients was 0.966 (95% CI: 9.94-9.99) for the weighted kappa coefficient and 0.985 (95% CI: 9.97-9.99) on the ICU discharge date assessment. The weighted κ coefficient showed an "almost perfect agreement" of 0.8 or higher. Conclusion The Japanese version of the IMS is a feasible tool with strong inter-rater reliability for the measurement of physical activity in ICU patients.

Early Mobilization and Rehabilitation of Critically-Ill Patients

Post-intensive care unit (ICU) syndrome may occur after ICU treatment and includes ICU-acquired weakness (ICU-AW), cognitive decline, and mental problems. ICU-AW is muscle weakness in patients treated in the ICU and is affected by the period of mechanical ventilation. Diaphragmatic weakness may also occur because of respiratory muscle unloading using mechanical ventilators. ICU-AW is an independent predictor of mortality and is associated with longer duration of mechanical ventilation and hospital stay. Diaphragm weakness is also associated with poor outcomes. Therefore, pulmonary rehabilitation with early mobilization and respiratory muscle training is necessary in the ICU after appropriate patient screening and evaluation and can improve ICU-related muscle weakness and functional deterioration.

The effects of inspiratory muscle training on physical function in critically ill adults: Protocol for a systematic review and meta-analysis

INTRODUCTION

Inspiratory muscle training (IMT) is one possible strategy to ameliorate respiratory muscle weakness due to invasive mechanical ventilation. Recent systematic reviews have focused on respiratory outcomes with minimal attention to physical function. The newest systematic review searched the literature until September 2017 and a recent preliminary search identified 5 new randomized controlled trials focusing on IMT in critical care. As such, a new systematic review is warranted to summarize the current body of evidence and to investigate the effect of IMT on physical function in critical care.

MATERIALS AND METHODS

We will search for three main concepts ("critical illness", "inspiratory muscle training", "RCT") across six databases from their inception (MEDLINE, EMBASE, Emcare, AMED, CINAHL, CENTRAL) and ClinicalTrials.gov. Two reviewers will independently screen titles, abstracts, and full texts for eligibility using the Covidence web-based software. Eligible studies must include: (1) adult (≥18 years) patients admitted to the intensive care unit (ICU) who required invasive mechanical ventilation for ≥24 hours, (2) an IMT intervention using a threshold device with the goal of improving inspiratory muscle strength, with or without usual care, and (3) randomized controlled trial design. The primary outcome of interest will be physical function. We will use the Cochrane Risk of Bias Tools (ROB2) and will assess the quality of the evidence using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) tool. This protocol has been reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA- P) guidelines and is registered with the International Prospective Register of Systematic Reviews (PROSPERO).

CONCLUSION

Results will summarize the body of evidence of the effect of IMT on physical function in critically ill patients. We will submit our findings to a peer-reviewed journal and share our results at conferences.

Effects of the High-Intensity Early Mobilization on Long-Term Functional Status of Patients with Mechanical Ventilation in the Intensive Care Unit

Objective

Intensive care unit (ICU)-acquired weakness often occurs in patients with invasive mechanical ventilation (IMV). Early active mobility may reduce ICU-acquired weakness, improve functional status, and reduce disability. The aim of this study was to investigate whether high-intensity early mobility improves post-ICU discharge functional status of IMV patients.

Methods

132 adult patients in the ICU who were undergoing IMV were randomly assigned into two groups with a ratio of 1 : 1, with one group received high-intensity early mobility (intervention group, IG), while the other group received conventional treatment (control group, CG). The functional status (Barthel Index (BI)), capacity of mobility (Perme score and ICU Mobility Scale (IMS)), muscle strength (Medical Research Council sum scores (MRC-SS)), mortality, complication, length of ICU stay, and duration of IMV were evaluated at ICU discharge or after 3-month of ICU discharge.

Results

The patient's functional status was improved (BI scores 90.6 ± 18.0 in IG vs. 77.7 ± 27.9 in CG; p=0.005), and capacity of mobility was increased (Perme score 17.6 ± 7.1 in IG vs. 12.2 ± 8.5 in CG, p < 0.001; IMS 4.7 ± 2.6 in IG vs. 3.0 ± 2.6 in CG, p < 0.001). The IG had a higher muscle strength and lower incidence of ICU-acquired weakness (ICUAW) than that in the CG. The incidence of mortality and delirium was also lower than CG at ICU discharge. However, there were no differences in terms of length of ICU stay, duration of IMV, ventilator-associated pneumonia, and venous thrombosis.

Conclusions

High-intensity early mobility improved the patient's functional status and increased capacity of mobility with IMV. The benefits to functional status remained after 3 month of ICU discharge. Other benefits included higher muscle strength, lower incidence of ICUAW, mortality, and delirium in IG.

Effects of acute phase intensive electrical muscle stimulation in COVID-19 patients requiring invasive mechanical ventilation: an observational case-control study

We investigated the effects of acute-phase intensive electrical muscle stimulation (EMS) on physical function in COVID-19 patients with respiratory failure requiring invasive mechanical ventilation (IMV) in the intensive care unit (ICU). Consecutive COVID-19 patients requiring IMV admitted to a university hospital ICU between January and April 2022 (EMS therapy group) or between March and September 2021 (age-matched historical control group) were included in this retrospective observational case-control study. EMS was applied to both upper and lower limb muscles for up to 2 weeks in the EMS therapy group. The study population consisted of 16 patients undergoing EMS therapy and 16 age-matched historical controls (median age, 71 years; 81.2% male). The mean period until initiation of EMS therapy after ICU admission was 3.2 ± 1.4 days. The EMS therapy group completed a mean of 6.2 ± 3.7 EMS sessions, and no adverse events occurred. There were no significant differences between the two groups in Medical Research Council sum score (51 vs. 53 points, respectively; P = 0.439) or ICU mobility scale at ICU discharge. Addition of upper and lower limb muscle EMS therapy to an early rehabilitation program did not result in improved physical function at ICU discharge in severe COVID-19 patients.

Age and period of ventilator use are related to walking independence at the time of discharge in patients with severe COVID-19 pneumonia: a single-center retrospective observational study

[Purpose] This study aimed to identify the factors and cutoffs associated with walking independence in patients with severe COVID-19 pneumonia. [Participants and Methods] In total, 112 patients with COVID-19 pneumonia (98 males and 14 females) who were hospitalized between March 2020 and August 2021 and underwent physiotherapy during mechanical ventilation were included in the study. Attributes, respiratory function, physical function, and bed-withdrawal status were compared between two groups of patients, who were classified according to their ability to walk independently at discharge. The independent variables were reduced to four components by principal component analysis. Logistic regression analysis was performed with walking independence at discharge as the dependent variable. Receiver operating characteristic curves for the extracted factors were drawn, and cutoff values were calculated. [Results] At discharge, 76 patients were able to walk independently, while 36 were not. The logistic regression analysis was adjusted according to age and mechanical ventilation time. Cutoffs were an age of 56 years and a ventilation period of 7.5 days. [Conclusion] In cases of patients with severe COVID-19 pneumonia who required ventilators, age and mechanical ventilation time were associated with ambulatory independence at discharge, indicating the importance of reducing the ventilation period by providing respiratory physiotherapy, including expectoration, positioning, and weaning.

Physiotherapy Approach to an Internal Capsule Infarct With Upper Motor Neuron Facial Nerve Palsy: A Case Report

The internal capsule (IC) is a vital brain structure housing descending and ascending fiber tracts, with traditional assumptions about the corticobulbar and corticospinal tracts descending through the genu and anterior third of the posterior limb of internal capsule (PLIC), respectively. However, observations of IC infarctions reveal that symptoms often deviate from the expected fiber pattern, prompting a deeper exploration of these complexities. The posterior limb of the IC receives its blood supply from the lenticulostriate branches of the middle cerebral artery and the anterior choroidal artery (AChA). AChA infarctions present a diverse array of symptoms beyond the classic triad, reflecting the intricate vascular supply and lesion patterns within this region. We present a case of a 74-year-old male farmer with right-hand dominance, who experienced a fall resulting in head and right lower limb injuries. Subsequently, he developed weakness in his left upper and lower limbs, facial deviation, slurred speech, and swelling in the right lower limb. Following these symptoms, his family promptly brought him to the hospital on November 30, 2023. Extensive investigations, including magnetic resonance imaging (MRI), revealed a hyper-acute infarct in the posterior limb of the left IC. The patient was admitted to the intensive care unit (ICU) for three days and later shifted to the neurology ward where medical management was commenced, including physiotherapy protocol that was started on December 2, 2023. Physiotherapy interventions were designed to address the patient's weakness, altered sensation, and diminished reflexes. Therapeutic goals focused on preventing complications, improving posture, enhancing range of motion (ROM), and mitigating breathing difficulties and mobility issues. The physiotherapy aimed to enhance the patient's overall physical and mental well-being, emphasizing independence and improved quality of life. Regular assessments and adjustments to the therapeutic interventions were made based on the patient's progress. This case underscores the importance of tailored physiotherapy interventions in addressing the diverse manifestations of IC infarctions, contributing to a comprehensive understanding of rehabilitation strategies in neurologically compromised individuals.

Survivorship outcomes for critically ill patients in Australia and New Zealand: A scoping review

INTRODUCTION

Impairments after critical illness, termed the post-intensive care syndrome, are an increasing focus of research in Australasia. However, this research is yet to be cohesively synthesised and/or summarised.

OBJECTIVE

The aim of this scoping review was to explore patient outcomes of survivorship research, identify measures, methodologies, and designs, and explore the reported findings in Australasia.

INCLUSION CRITERIA

Studies reporting outcomes for adult survivors of critical illness from Australia and New Zealand in the following domains: physical, functional, psychosocial, cognitive, health-related quality of life (HRQoL), discharge destination, health care use, return to work, and ongoing symptoms/complications of critical illness.

METHODS

The Joanna Briggs Institute scoping review methodology framework was used. A protocol was published on the open science framework, and the search used Ovid MEDLINE, Scopus, ProQuest, and Google databases. Eligible studies were based on reports from Australia and New Zealand published in English between January 2000 and March 2022.

RESULTS

There were 68 studies identified with a wide array of study aims, methodology, and designs. The most common study type was nonexperimental cohort studies (n = 17), followed by studies using secondary analyses of other study types (n = 13). HRQoL was the most common domain of recovery reported. Overall, the identified studies reported that impairments and activity restrictions were associated with reduced HRQoL and reduced functional status was prevalent in survivors of critical illness. About 25% of 6-month survivors reported some form of disability. Usually, by 6 to12 months after critical illness, impairments had improved.

CONCLUSIONS

Reports of long-term outcomes for survivors of critical illness in Australia highlight that impairments and activity limitations are common and are associated with poor HRQoL. There was little New Zealand-specific research related to prevalence, impact, unmet needs, ongoing symptoms, complications from critical illness, and barriers to recovery.

Extracorporeal Life Support Organization Registry International Report 2022: 100,000 Survivors

The Extracorporeal Life Support Organization (ELSO) maintains the world's largest extracorporeal membrane oxygenation (ECMO) registry by volume, center participation, and international scope. This 2022 ELSO Registry Report describes the program characteristics of ECMO centers, processes of ECMO care, and reported outcomes. Neonates (0-28 days), children (29 days-17 years), and adults (≥18 years) supported with ECMO from 2009 through 2022 and reported to the ELSO Registry were included. This report describes adjunctive therapies, support modes, treatments, complications, and survival outcomes. Data are presented descriptively as counts and percent or median and interquartile range (IQR) by year, group, or level. Missing values were excluded before calculating descriptive statistics. Complications are reported per 1,000 ECMO hours. From 2009 to 2022, 154,568 ECMO runs were entered into the ELSO Registry. Seven hundred and eighty centers submitted data during this time (557 in 2022). Since 2009, the median annual number of adult ECMO runs per center per year increased from 4 to 15, whereas for pediatric and neonatal runs, the rate decreased from 12 to 7. Over 50% of patients were transferred to the reporting ECMO center; 20% of these patients were transported with ECMO. The use of prone positioning before respiratory ECMO increased from 15% (2019) to 44% (2021) for adults during the coronavirus disease-2019 (COVID-19) pandemic. Survival to hospital discharge was greatest at 68.5% for neonatal respiratory support and lowest at 29.5% for ECPR delivered to adults. By 2022, the Registry had enrolled its 200,000th ECMO patient and 100,000th patient discharged alive. Since its inception, the ELSO Registry has helped centers measure and compare outcomes across its member centers and strategies of care. Continued growth and development of the Registry will aim to bolster its utility to patients and centers.

Prognostic factors in mobility disability among elderly patients in the emergency department: A single-center retrospective study

Aim

We aimed to evaluate the clinical characteristics and outcomes of elderly critically ill patients and identify prognostic factors for mobility disability at discharge.

Methods

This single-center, retrospective cohort study investigated the period from April 2020 to January 2021. Patients ≥75 years old transferred to our emergency department and admitted to the intensive care unit (ICU) or intermediate unit in our hospital were eligible. Demographics, clinical characteristics, nutritional indicators, and nutritional screening scores were collected from chart reviews and analyzed. The primary outcome was the prevalence of mobility disability, compared to that of no mobility disability.

Results

A total of 124 patients were included in this present study. Median age was 83.0 years (interquartile range [IQR], 79.8-87.0 years) and 48 patients (38.7%) were female. Fifty-two patients (41.9%) could not walk independently at discharge (mobility disability group). The remaining 72 patients were in the no mobility disability group. Multiple logistic regression analyses revealed clinical frailty scale (CFS) score ≥5 (odds ratio [OR] = 6.63, 95% confidence interval [CI] = 2.51-17.52, p < 0.001), SOFA score ≥6 (OR = 6.11, 95% CI = 1.57-23.77, p = 0.009), and neurological disorder as the main cause on admission (OR = 4.48, 95% CI = 1.52-13.20, p = 0.006) were independent and significant prognostic factors for mobility disability at discharge.

Conclusion

Among elderly patients admitted to the emergency department, CFS ≥5, SOFA ≥6, and neurological disorders were associated with mobility disability at hospital discharge.

Effects of mobility dose on discharge disposition in critically ill stroke patients

BACKGROUND

Mobilization in the intensive care unit (ICU) has the potential to improve patient outcomes following acute stroke. The optimal duration and intensity of mobilization for patients with hemorrhagic or ischemic stroke in the ICU remain unclear.

OBJECTIVE

To assess the effect of mobilization dose in the ICU on adverse discharge disposition in patients after stroke.

DESIGN

This is an international, prospective, observational cohort study of critically ill stroke patients (November 2017-September 2019). Duration and intensity of mobilization was quantified daily by the mobilization quantification score (MQS).

SETTING

Patients requiring ICU-level care were enrolled within 48 hours of admission at four separate academic medical centers (two in Europe, two in the United States).

PARTICIPANTS

Participants included individuals (>18 years old) admitted to an ICU within 48 hours of ischemic or hemorrhagic stroke onset who were functionally independent at baseline.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

The primary outcome was adverse discharge disposition.

RESULTS

Of the patients screened, 163 were eligible for inclusion in the study. One patient was subsequently excluded due to insufficient data collection (n = 162). The dose of mobilization varied greatly between centers and patients, which could not be explained by patients' comorbidities or disease severity. High dose of mobilization (mean MQS > 7.3) was associated with a lower likelihood of adverse discharge (adjusted odds ratio, [aOR]: 0.14; 95% confidence interval [CI]: 0.06-0.31; p < .01).

CONCLUSION

The increased use of mobilization acutely in the ICU setting may improve patient outcomes.

Passive Movements Do not Appear to Prevent or Reduce Joint Stiffness in Medium to Long-Stay ICU Patients: A Randomized, Controlled, Within-Participant Trial

OBJECTIVES

ICU patients have an increased risk of joint stiffness because of their critical illness and reduced mobility. There is a paucity of evidence evaluating the efficacy of passive movements (PMs). We investigated whether PMs prevent or reduce joint stiffness in ICU patients.

DESIGN

A randomized, controlled, within-participant, assessor-blinded study.

SETTING

A 48-bed tertiary care adult ICU.

PATIENTS

Intubated patients who were expected to be invasively mechanically ventilated for greater than 48 hours with an ICU length of stay greater than or equal to 5 days, and unable to voluntarily move their limbs through full range of motion (ROM).

INTERVENTIONS

The ankle and elbow on one side of each participant's body received PMs (10 min each joint, morning and afternoon, 5 d/wk). The other side acted as the control. The PMs intervention continued for as long as clinically indicated to a maximum of 4 weeks.

MEASUREMENTS

The primary outcome was ankle dorsiflexion ROM at cessation of PMs. Plantarflexion, elbow flexion and extension ROM, and participant-reported joint pain and stiffness (verbal analog scale [VAS]) were also measured. Outcomes were recorded at baseline and cessation of PMs. For participants whose PMs intervention ceased early due to recovery, additional post-early-cessation of PMs review measurements were undertaken as near as possible to 4 weeks.

MAIN RESULTS

We analyzed data from 25 participants with a median (interquartile range) ICU stay of 15.6 days (11.3-25.4). The mean (95% CI) between-side difference for dorsiflexion ROM (with knee extension) at cessation of PMs was 0.4 degrees (-4.4 to 5.2; p = 0.882), favoring the intervention side, indicating there was not a clinically meaningful effect of 5 degrees. No statistically significant differences were found between the intervention and control sides for any ROM or VAS data.

CONCLUSIONS

PMs, as provided to this sample of medium to long-stay ICU patients, did not prevent or reduce joint stiffness.

Relationship of Age And Mobility Levels During Physical Rehabilitation With Clinical Outcomes in Critical Illness

Objective

To determine whether age, mobility level, and change in mobility level across the first 3 physical rehabilitation sessions associate with clinical outcomes of patients who are critically ill.

Design

Retrospective, observational cohort study.

Setting

Medical Intensive Care Unit (MICU).

Participants

Hospitalized adults (n = 132) who received 3 or more, consecutive rehabilitation sessions in the MICU.

Interventions

Not applicable.

Measurements and Main Results

Sample included 132 patients with 60 (45%) classified as younger (18-59 years) and 72 (55%) as older (60+ years). The most common diagnosis was sepsis/septicemia (32.6%). Older relative to younger patients had a significantly slower rate of improvement in ICU Mobility Scale (IMS) scores across rehabilitation sessions (mean slope coefficient 0.3 vs 0.6 points, P<.001), were less likely to be discharged to home (30.6% vs 55.0%, P=.005), and were more likely to die within 12 months (41.7% vs 25.0%, P=.046). Covariate-adjusted models indicated greater early improvement in IMS scores were associated with discharge home (P=.005). Longer time to first rehabilitation session, lower initial IMS scores, and slower improvement in IMS scores were associated with increased ICU days (all P<.03).

Conclusion

Older age and not achieving the mobility milestone of sitting at edge of bed or limited progression of mobility across sessions is associated with poor patient outcomes. Our findings suggest that age and mobility level contribute to outcome prognostication, and can aide in clinical phenotyping and rehabilitative service allocation.

Association Between Mobilization Level And Activity of Daily Living Independence in Critically Ill Patients

OBJECTIVE

To examine the association between the mobilization level during intensive care unit (ICU) admission and independence in activity of daily living (ADL), defined as Barthel Index (BI)≥70.

METHODS

This was a post-hoc analysis of the EMPICS study involving nine hospitals. Consecutive patients who spend >48 hours in the ICU were eligible for inclusion. Mobilization was performed at each hospital according to the shared protocol and the highest ICU mobility score (IMS) during the ICU stay, baseline characteristics, and BI at hospital discharge. Multiple logistic regression analysis, adjusted for baseline characteristics, was used to deter-mine the association between the highest IMS (using the receiver operating characteristic [ROC]) and ADL.

RESULTS

Of the 203 patients, 143 were assigned to the ADL independence group and 60 to the ADL dependence group. The highest IMS score was significantly higher in the ADL independence group than in the dependence group and was a predictor of ADL independence at hospital discharge (odds ratio, 1.22; 95% confidence interval, 1.07-1.38; adjusted p=0.002). The ROC cutoff value for the highest IMS was 6 (specificity, 0.67; sensitivity, 0.70; area under the curve, 0.69).

CONCLUSION

These results indicate that, in patients who were in the ICU for more than 48 hours, that patients with good function in the ICU also exhibit good function upon discharge. However, prospective, multicenter trials are needed to confirm this conclusion.

Early mobilisation in critically ill COVID-19 patients: a subanalysis of the ESICM-initiated UNITE-COVID observational study

BACKGROUND

Early mobilisation (EM) is an intervention that may improve the outcome of critically ill patients. There is limited data on EM in COVID-19 patients and its use during the first pandemic wave.

METHODS

This is a pre-planned subanalysis of the ESICM UNITE-COVID, an international multicenter observational study involving critically ill COVID-19 patients in the ICU between February 15th and May 15th, 2020. We analysed variables associated with the initiation of EM (within 72 h of ICU admission) and explored the impact of EM on mortality, ICU and hospital length of stay, as well as discharge location. Statistical analyses were done using (generalised) linear mixed-effect models and ANOVAs.

RESULTS

Mobilisation data from 4190 patients from 280 ICUs in 45 countries were analysed. 1114 (26.6%) of these patients received mobilisation within 72 h after ICU admission; 3076 (73.4%) did not. In our analysis of factors associated with EM, mechanical ventilation at admission (OR 0.29; 95% CI 0.25, 0.35; p = 0.001), higher age (OR 0.99; 95% CI 0.98, 1.00; p ≤ 0.001), pre-existing asthma (OR 0.84; 95% CI 0.73, 0.98; p = 0.028), and pre-existing kidney disease (OR 0.84; 95% CI 0.71, 0.99; p = 0.036) were negatively associated with the initiation of EM. EM was associated with a higher chance of being discharged home (OR 1.31; 95% CI 1.08, 1.58; p = 0.007) but was not associated with length of stay in ICU (adj. difference 0.91 days; 95% CI - 0.47, 1.37, p = 0.34) and hospital (adj. difference 1.4 days; 95% CI - 0.62, 2.35, p = 0.24) or mortality (OR 0.88; 95% CI 0.7, 1.09, p = 0.24) when adjusted for covariates.

CONCLUSIONS

Our findings demonstrate that a quarter of COVID-19 patients received EM. There was no association found between EM in COVID-19 patients' ICU and hospital length of stay or mortality. However, EM in COVID-19 patients was associated with increased odds of being discharged home rather than to a care facility. Trial registration ClinicalTrials.gov: NCT04836065 (retrospectively registered April 8th 2021).

Functional recovery of chronically critically ill patients in the first days after discharge from the intensive care unit: Feasibility of the 6-minute step test

BACKGROUND

Survivors of chronic critical illness often experience weakness and functional dependence to various degrees after their intensive care unit (ICU) stay. Evaluating their functional status with the traditional six-minute walk test is challenging due to space constraints or patient intolerance.

OBJECTIVE

Our aim was to evaluate the feasibility of using the six-minute step test (6MST) as a measure of functional capacity in chronically critically ill patients early after ICU discharge.

METHODS

This prospective study was undertaken in a private Brazilian hospital. From July 2019 to July 2020, all chronically critically ill patients were asked to participate 48 hours after ICU discharge. On the day of study inclusion and a week later, those who consented underwent functional assessment comprised of the 6MST, peripheral muscle strength using handgrip strength (HGS), and mobility using the ICU mobility scale (IMS).

RESULTS

A total of 40 patients were included. The 6MST was feasible in 40% on the first evaluation and 57% on the second. The median 6MST was 0 [0-5] on the first evaluation and 3.5 [0-7.75] on the second (P = 0.005). The median HGS increased from 11.50 [9.25-18] on the first evaluation to 14.5 [10-20] on the second (P = 0.006). The median IMS was 4.5 [3.25-7] on the first evaluation and 6 [3.25-7] on the second (P<0.001). Despite the significant improvement, all parameters measured remained well below normal.

CONCLUSION

The 6MST was a feasible measure of functional capacity in chronically critically ill patients early after ICU discharge. Patients had functional capacity well below predicted values.
