OBJECTIVE

The authors' objective with this narrative review is to explore the impact of rehabilitative interventions at each stage of liver disease. TYPE: Narrative review.

LITERATURE SURVEY

Literature search conducted in Medline, Embase, and Google Scholar databases.

METHODOLOGY

Articles were included if they were identified in one of the three database, written in English, peer-reviewed, and involved human participants without any restrictions on the publication date. Reference lists of these publications were also scrutinized for other articles that might be relevant. Elibigle articles were reviewed to determine whether they met inclusion crtieria.

SYNTHESIS

Authors synthesized findings in the eligible articles to create a narrative summary.

CONCLUSIONS

Chronic liver disease is a major cause of morbidity and mortality across the globe. Cirrhosis causes alterations in metabolic and circulatory functions that negatively affect nutritional status and exercise capacity. Frailty is identified in nearly half of patients with advanced liver disease and bears a poor prognosis. Exercise and nutritional interventions improve key components of physical frailty and quality of life in chronic liver disease and after liver transplantation. Early mobility is generally recommended following liver transplantation and deemed to be safe and feasible. Inpatient rehabilitation may be considered in patients who require ongoing daily medical management by a physician, demonstrate a significant functional decline from their baseline, tolerate intensive rehabilitation, and have functional goals that can be addressed by at least two skilled therapies. Rehabilitation is safe and improves outcomes at every stage of liver disease from cirrhosis to following transplantation. This literature review explores the impact of rehabilitative interventions at each stage of liver disease from cirrhosis to transplantation and beyond.

Reporting of nutritional screening, status, and intake in trials of nutritional and physical rehabilitation following critical illness: a systematic review

BACKGROUND

Surviving critical illness leads to prolonged physical and functional recovery with both nutritional and physical rehabilitation interventions for prevention and treatment being investigated. Nutritional status and adequacy may influence outcome, but no consensus on which nutritional-related variables should be measured and reported in clinical trials exists.

OBJECTIVES

This study aimed to undertake a systematic review investigating the reporting of nutritional screening, nutritional status, and nutritional intake/delivery in randomized controlled trials (RCTs) evaluating nutritional and/or physical rehabilitation on physical and functional recovery during and following critical illness.

METHODS

Five electronic databases (MEDLINE, Web of Science, EMBASE, CINAHL, and Cochrane) were searched (last update 9 August, 2023). Search terms included both free text and standardized indexed terms. Studies included were RCTs assessing nutritional and/or physical interventions either during or following intensive care unit (ICU) admission in adults (18 y or older) with critical illness, and who required invasive mechanical ventilation for any duration during ICU admission. Study quality was assessed using the Cochrane Collaboration Risk of Bias tool for RCTs and descriptive data synthesis was performed and presented as counts (%). n t RESULTS: In total, 123 RCTs (30 nutritional, 87 physical function, and 6 combined) were included. Further, ≥1 nutritional variable was measured and/or reported in 99 (80%) of the studies including BMI (n = 69), body weight (n = 57), nutritional status (n = 11), nutritional risk (n = 10), energy delivery (n = 41), protein delivery (n = 35), handgrip strength (n = 40), and other nutritional-related muscle variables (n = 41). Only 3 studies were considered to have low risk of bias in all categories.

CONCLUSIONS

Few RCTs of physical rehabilitation measure and report nutritional or related variables. Future studies should measure and report specific nutritional factors that could impact physical and functional recovery to support interpretation where studies do not show benefit. This protocol was preregistered at PROSPERO as CRD42022315122.

A Focused Update to the Clinical Practice Guidelines for the Prevention and Management of Pain, Anxiety, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the ICU

RATIONALE

Critically ill adults are at risk for a variety of distressing and consequential symptoms both during and after an ICU stay. Management of these symptoms can directly influence outcomes.

OBJECTIVES

The objective was to update and expand the Society of Critical Care Medicine's 2018 Clinical Practice Guidelines for the Prevention and Management of Pain, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the ICU.

PANEL DESIGN

The interprofessional inclusive guidelines task force was composed of 24 individuals including nurses, physicians, pharmacists, physiotherapists, psychologists, and ICU survivors. The task force developed evidence-based recommendations using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. Conflict-of-interest policies were strictly followed in all phases of the guidelines, including task force selection and voting.

METHODS

The task force focused on five main content areas as they pertain to adult ICU patients: anxiety (new topic), agitation/sedation, delirium, immobility, and sleep disruption. Using the GRADE approach, we conducted a rigorous systematic review for each population, intervention, control, and outcome question to identify the best available evidence, statistically summarized the evidence, assessed the quality of evidence, and then performed the evidence-to-decision framework to formulate recommendations.

RESULTS

The task force issued five statements related to the management of anxiety, agitation/sedation, delirium, immobility, and sleep disruption in adults admitted to the ICU. In adult patients admitted to the ICU, the task force issued conditional recommendations to use dexmedetomidine over propofol for sedation, provide enhanced mobilization/rehabilitation over usual mobilization/rehabilitation, and administer melatonin. The task force was unable to issue recommendations on the administration of benzodiazepines to treat anxiety, and the use of antipsychotics to treat delirium.

CONCLUSIONS

The guidelines task force provided recommendations for pharmacologic management of agitation/sedation and sleep, and nonpharmacologic management of immobility in critically ill adults. These recommendations are intended for consideration along with the patient's clinical status.

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.

Neuromuscular electrical stimulation, muscle mass, and physical function decline in the early phase after living donor liver transplantation

This study aims to investigate the effects of neuromuscular electrical stimulation (NMES) in addition to conventional early mobilization in the early postoperative period after living donor liver transplantation (LTx) on body composition and physical function. This was a retrospective single-center cohort study. Adult subjects who were admitted for living donor LTx from 2018 to 2023 were included in the analysis. After April 2020, patients underwent 4 weeks of NMES in addition to conventional rehabilitation. The skeletal muscle mass index, body cell mass, and physical function, including the 6-minute walking distance, were assessed before surgery and at discharge, and changes in these outcomes were compared before and after the introduction of NMES. Sixty-one patients were in the NMES group, and 53 patients before the introduction of NMES were in the control group. ANCOVA with etiology, obstructive ventilatory impairment, Child-Pugh classification, and initial body composition value as covariates demonstrated that there was a significantly smaller decline of body cell mass (-2.9±2.7 kg vs. -4.4±2.7 kg, p = 0.01), as well as of the skeletal muscle mass index (-0.78±0.73 kg/m 2 vs. -1.29±1.21 kg/m 2 , p = 0.04), from baseline to discharge in the NMES group than in the control group; thus, the decline after surgery was suppressed in the NMES group. Four weeks of NMES, in addition to conventional rehabilitation in the early period after LTx, may attenuate the deterioration of muscle mass. It is suggested that NMES is an option for developing optimized rehabilitation programs in the acute postoperative period after LTx.

Impact of Adding Bedside Cycling to Intensive Care Unit Rehabilitation on Physical Function and Length of Stay After Liver Transplantation: A Randomized Controlled Trial

OBJECTIVE

To assess the effectiveness of early bedside cycling training in enhancing recovery among patients following liver transplantation.

METHODS

A total of 64 patients who underwent liver transplantation were randomly assigned to either an experimental group or a control group, with 32 patients in each group. Patients in the control group received routine rehabilitation training after postoperative consciousness recovery and tracheal extubation. The experimental group received supplemental lower limb bedside cycling training in addition to the routine rehabilitation. Differences in physical function, length of intensive care unit, and hospital stays were compared between the two groups.

RESULTS

The experimental group showed significantly greater improvements in physical function, such as activities of daily living scores and Berg Balance Scale scores, compared to the control group (P < .05). While the experimental group also exhibited decreased length of intensive care unit and hospital stays compared to the control group, these differences lacked statistical significance.

CONCLUSION

Early bedside cycling training contributes to enhanced physical function, such as balance function and activities of daily living, among patients undergoing liver transplantation.

Estimation of lifetime costs for patients receiving a transplant: the case of liver transplantation related to hepatitis B in Italy

Introduction

In Italy, post-liver transplant (LT) hepatitis B virus (HBV) reinfection prophylaxis is frequently based on a combined regimen of anti-HBV immunoglobulin (HBIG) and oral antivirals. However, little information is available at the national level on the cost of LT and the contribution of HBV prophylaxis. This study aimed to quantify the direct healthcare cost for adult patients undergoing LT for HBV-related disease over a lifetime horizon and from the perspective of a National Healthcare Service.

Methods

A pharmaco-economic model was implemented with a 4-tiered approach consisting of 1) preliminary literature research to define the research question; 2) pragmatic literature review to retrieve existing information and inform the model; 3) micro-simulated patient cycles; and 4) validation from a panel of national experts.

Results

The average lifetime healthcare cost of LT for HBV-related disease was €395,986. The greatest cost drivers were post-transplant end-stage renal failure (31.9% of the total), immunosuppression (20.6%), and acute transplant phase (15.8%). HBV reinfection prophylaxis with HBIG and antivirals accounted for 12.4% and 6.4% of the total cost, respectively; however, lifetime HBIG prophylaxis was only associated with a 6.6% increase (~€422 k). Various sensitivity analyses have shown that discount rates have the greatest impact on total costs.

Conclusion

This analysis showed that the burden of LT due to HBV is not only clinical but also economic.

Early mobility and family partnerships in the intensive care unit: A scoping review of reviews

BACKGROUND

Critical illness significantly impacts the well-being of patients and families. Previous studies show that family members are willing to participate in patient care. Involving families in early mobility interventions may contribute to improved recovery and positive outcomes for patients and families.

AIM

In this scoping review, we investigated early mobility interventions for critically ill patients evaluated in randomized controlled trials and the extent to which family engagement in those interventions are reported in the literature.

STUDY DESIGN

In this scoping review of reviews, EMBASE, CINAHL, PubMed and Cochrane Central databases were searched in October 2019 and updated in February 2022. Systematic reviews were included and assessed using A MeaSurement Tool to Assess Systematic Reviews (AMSTAR) 2. Data were synthesized using a narrative approach. PRISMA-ScR guidelines were adhered to for reporting.

RESULTS

Thirty-three reviews were included which described a range of early mobility interventions for critically ill patients; none explicitly mentioned family engagement. Almost half of the reviews were of low or critically low quality. Insufficient detail of early mobility interventions prompted information to be extracted from the primary studies.

CONCLUSIONS

There are a range of early mobility interventions for critically ill patients but few involve families. Given the positive outcomes of family participation, and family willingness to participate in care, there is a need to explore the feasibility and acceptability of family participation in early mobility interventions.

RELEVANCE TO CLINICAL PRACTICE

Family engagement in early mobility interventions for critically ill patients should be encouraged and supported. How to best support family members and clinicians in enacting family involvement in early mobility requires further investigation.

Association of active mobilisation variables with adverse events and mortality in patients requiring mechanical ventilation in the intensive care unit: a systematic review and meta-analysis

BACKGROUND

Mobilisation during critical illness is now included in multiple clinical practice guidelines. However, a large, randomised trial and systematic review have recently identified an increased probability of adverse events and mortality in patients who received early active mobilisation in the intensive care unit (ICU). We aimed to determine the effects of mobilisation compared with usual care on adverse events and mortality in an acute ICU setting. In subgroup analyses, we specifically aimed to investigate possible sources of harm, including the timing and duration of mobilisation achieved, ventilation status, and admission diagnosis.

METHODS

In this systematic review with frequentist and Bayesian analyses, we searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials, CINAHL, SPORTDiscus, SCOPUS, Web of Science, and PEDro electronic databases, as well as clinical trial registries (ICTRP and ClinicalTrials.gov), from inception to March 16, 2023, without language restrictions. Eligible studies were randomised controlled trials that examined active mobilisation compared with either no mobilisation or mobilisation commencing later, or at a lower frequency or intensity, in adults who were critically ill during or after a period of mechanical ventilation in an acute ICU setting. Two authors independently screened reports, extracted data, and assessed the risk of bias using the Cochrane risk-of-bias tool (version 1). The primary outcome was the number of adverse events that occurred during the implementation of mobilisation, with the effect of mobilisation on mortality being the secondary outcome. Risk ratios (RRs) with 95% CIs were calculated in R (version 4.0.3) using random-effects modelling, with Bayesian analysis completed to calculate the probability of treatment harm (ie, RR >1). Subgroup analyses were completed to investigate the association of various factors of mobilisation on adverse events and mortality: duration of mobilisation (longer [≥20 min per day] vs shorter [<20 min per day]), timing of commencement (early [≤72 h from ICU admission] vs late [>72 h from ICU admission]), ventilation status at commencement (all patients mechanically ventilated vs all patients extubated), and ICU admission diagnosis (surgical vs medical). This study was registered with PROSPERO, CRD42022369272.

FINDINGS

After title and abstract screening of 14 440 studies and review of 466 full texts, 67 trials with 7004 participants met inclusion criteria, with 59 trials contributing to the meta-analysis. Of the 67 included studies, 15 (22%) did not mention adverse events and 13 (19%) reported no adverse events occurring across the trial period. Overall, we found no effect of mobilisation compared with usual care on the occurrence of adverse events (RR 1·09 [95% CI 0·69-1·74], p=0·71; I2 91%; 32 731 events, 20 studies; very low certainty), with a 2·96% occurrence rate (693 events in 23 395 intervention sessions; 25 studies). Mobilisation did not have any effect on mortality (RR 0·98 [95% CI 0·87-1·12], p=0·81; I2 0%; n=6218, 58 studies; moderate certainty). Subgroup analysis was hindered by the large amount of data that could not be allocated and analysed, making the results hypothesis generating only.

INTERPRETATION

Implementation of mobilisation in the ICU was associated with a less than 3% chance of an adverse event occurring and was not found to increase adverse events or mortality overall, providing reassurance for clinicians about the safety of performing this intervention. Subgroup analyses did not clearly identify any specific variable of mobilisation implementation that increased harm.

FUNDING

None.

Adverse events related to physiotherapy practice: a scoping review

Introduction

While adverse events related to physiotherapy are possible, the type of adverse event and the area of physiotherapy practice in which they occur are not well understood. The purpose of this scoping review was to establish adverse events related to physiotherapy practice and understand the nature of these events and the circumstances in which they occurred.

Methods

Relevant literature from January 2014 to February 2024 was gathered from five electronic databases. Studies reporting adverse events within any physiotherapy practice (intervention or assessment) were eligible. Two reviewers independently assessed title and abstract, and full texts. Findings were synthesised by clinical streams.

Results

A total of 58 studies met the inclusion criteria. Common adverse events described in musculoskeletal physiotherapy involving manual therapy, exercise and electrotherapy were increased pain and stiffness. Cardiorespiratory physiotherapy interventions involving early mobilisation, exercise and airway clearance therapy reported desaturation and haemodynamic instability. Neurological physiotherapy studies reported falls and fatigue during gait and balance training and exercise. Oncology and aged care interventions involving exercise, balance training and lymphoedema management reported increased pain and muscle strain while studies including pelvic floor muscle training reported the adverse event of vaginal discomfort.

Conclusion

This review identified adverse events occurring during physiotherapy interventions or assessment procedures. Increased monitoring and proactive safety measures may be necessary to ensure patient safety during these treatments.

Japanese Clinical Practice Guidelines for Rehabilitation in Critically Ill Patients 2023 (J-ReCIP 2023)

Providing standardized, high-quality rehabilitation for critically ill patients is a crucial issue. In 2017, the Japanese Society of Intensive Care Medicine (JSICM) promulgated the "Evidence-Based Expert Consensus for Early Rehabilitation in the Intensive Care Unit" to advocate for the early initiation of rehabilitations in Japanese intensive care settings. Building upon this seminal work, JSICM has recently conducted a rigorous systematic review utilizing the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology. This endeavor resulted in the formulation of Clinical Practice Guidelines (CPGs), designed to elucidate best practices in early ICU rehabilitation. The primary objective of this guideline is to augment clinical understanding and thereby facilitate evidence-based decision-making, ultimately contributing to the enhancement of patient outcomes in critical care settings. No previous CPGs in the world has focused specifically on rehabilitation of critically ill patients, using the GRADE approach. Multidisciplinary collaboration is extremely important in rehabilitation. Thus, the CPGs were developed by 73 members of a Guideline Development Group consisting of a working group, a systematic review group, and an academic guideline promotion group, with the Committee for the Clinical Practice Guidelines of Early Mobilization and Rehabilitation in Intensive Care of the JSICM at its core. Many members contributed to the development of the guideline, including physicians and healthcare professionals with multiple and diverse specialties, as well as a person who had been patients in ICU. Based on discussions among the group members, eight important clinical areas of focus for this CPG were identified. Fourteen important clinical questions (CQs) were then developed for each area. The public was invited to comment twice, and the answers to the CQs were presented in the form of 10 GRADE recommendations and commentary on the four background questions. In addition, information for each CQ has been created as a visual clinical flow to ensure that the positioning of each CQ can be easily understood. We hope that the CPGs will be a useful tool in the rehabilitation of critically ill patients for multiple professions.

Novel Endpoints in Solid Organ Transplantation: Targeting Patient-reported Outcome Measures

Although solid organ transplantation improves survival and quality of life in many patients with organ failure, treatment complications and side effects can have debilitating consequences for patients. Patient-reported outcome measures (PROMs) capture how patients feel and function, including quality of life, symptoms, and side effects that are assessed directly by patients. Yet, they remain infrequently reported in trials in solid organ transplantation. Barriers to implementing PROMs in trials include uncertainty in selecting appropriate PROMs, concerns about resources limitations, patient burden, and limited evidence to support the psychometric robustness of measures for use in transplant recipients. In recent years, there have been increasing efforts to include patient-reported outcomes that are important to patients in trials to ensure that trials provide patient-centered information for decision-making. This article will provide an overview of PROMs, discuss PROs that are important to solid organ transplant recipients and those that are used in trials in solid organ transplantation, and outline approaches for selecting PROMs for clinical trials.

A systematic review of the effect of early mobilisation on length of stay for adults in the intensive care unit

BACKGROUND

EM has been hypothesized to help prevent the development of ICU acquired weakness and may therefore result in positive outcomes for ICU patients.

AIM

To establish the impact of Early mobilisation (EM) on adult Intensive Care Unit (ICU) patients in terms of ICU length of stay (LOS), as well as hospital LOS, duration of mechanical ventilation, mortality, and functional independence.

STUDY DESIGN

A Systematic Review. EMBASE, MEDLINE, CINAHL, and the Cochrane Library were searched on 24th November 2020. Included studies and other systematic reviews were hand-searched for further includable studies. The primary outcome was ICU LOS whilst secondary outcomes were duration of MV, mortality, hospital LOS and functional independence. The PRISMA guidelines were utilized to perform the review. Ten randomized controlled trials with a combined total of 1291 patients met inclusion criteria and were scrutinized using the Joanna Briggs Institute (JBI) Checklist for Systematic Reviews. Revman 5.4.1 was used to conduct meta-analysis were possible.

RESULTS

Results were limited by the evidence available for inclusion, in particular small sample sizes. However, a trend towards a shorter duration of ICU LOS and duration of mechanical ventilation emerged. There was also a trend towards higher rates of functional independence for intervention groups. Mortality rates appeared unaffected and results of meta-analysis were statistically non-significant (p = 0.90).

CONCLUSION

By applying a stricter time limit than previous systematic reviews a trend emerged that the commencement of EM has a positive effect on patient outcomes, in particular ICU LOS.

RELEVANCE TO CLINICAL PRACTICE

The evidence base surrounding EM remains poor; however on the balance of the available evidence the application of EM should not be delayed.

Exercise interventions for adults after liver transplantation

BACKGROUND

The finding that exercise is inversely related to metabolic syndrome after transplantation is novel and suggests that exercise interventions might provide a means for reducing metabolic syndrome complications in liver transplantation recipients. The use of exercise for increasing the physical activity daily levels by more frequent, higher intensity, and longer duration of training sessions, or the sum of these components may be necessary to counteract the effects of the pretransplant reduced activity, metabolic disturbances, and post-transplant immunosuppression, as well as improve physical function and aerobic capacity following liver transplantation. Regular physical activity has a long-term positive impact on recovery following various surgical procedures including transplantation, giving people the opportunity to return to an active life with their families, in society, and in their professional life. Likewise, specific muscle strength training may attenuate the loss of strength after liver transplantation.

OBJECTIVES

To evaluate the benefits and harms of exercise-based interventions in adults after liver transplantation compared to no exercise, sham interventions, or another type of exercise.

SEARCH METHODS

We used standard, extensive Cochrane search methods. The latest search date was 2 September 2022.

SELECTION CRITERIA

We included randomised clinical trials in liver transplantation recipients comparing any type of exercise with no exercise, sham interventions, or another type of exercise.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our primary outcomes were 1. all-cause mortality; 2. serious adverse events; and 3. health-related quality of life. Our secondary outcomes were 4. a composite of cardiovascular mortality and cardiac disease; 5. aerobic capacity; 6. muscle strength; 7. morbidity; 8. non-serious adverse events; and 9. cardiovascular disease post-transplantation. We assessed risk of bias of the individual trials using RoB 1, described the interventions using the TIDieR checklist, and used GRADE to assess certainty of evidence.

MAIN RESULTS

We included three randomised clinical trials. The trials randomised 241 adults with liver transplantation, of which 199 participants completed the trials. The trials were conducted in the USA, Spain, and Turkey. They compared exercise versus usual care. The duration of the interventions ranged from two to 10 months. One trial reported that 69% of participants who received the exercise intervention were adherent to the exercise prescription. A second trial reported a 94% adherence to the exercise programme, with participants attending 45/48 sessions. The remaining trial reported a 96.8% adherence to the exercise intervention during the hospitalisation period. Two trials received funding; one from the National Center for Research Resources (US) and the other from Instituto de Salud Carlos III (Spain). The remaining trial did not receive funding. All trials were at an overall high risk of bias, derived from high risk of selective reporting bias and attrition bias in two trials. The results on all-cause mortality showed a higher risk of death in the exercise group versus the control group, but these results are very uncertain (risk ratio (RR) 3.14, 95% confidence interval (CI) 0.74 to 13.37; 2 trials, 165 participants; I² = 0%; very low-certainty evidence). The trials did not report data on serious adverse events excluding mortality or non-serious adverse events. However, all trials reported that there were no adverse effects associated with exercise. We are very uncertain on whether exercise compared with usual care has a beneficial or harmful effect on health-related quality of life assessed using the 36-item Short Form Physical Functioning subscale at the end of the intervention (mean difference (MD) 10.56, 95% CI -0.12 to 21.24; 2 trials, 169 participants; I² = 71%; very low-certainty evidence). None of the trials reported data on composite of cardiovascular mortality and cardiovascular disease, and cardiovascular disease post-transplantation. We are very uncertain if there are differences in aerobic capacity in terms of VO2peak at the end of the intervention between groups (MD 0.80, 95% CI -0.80 to 2.39; 3 trials, 199 participants; I² = 0%; very low-certainty evidence). We are very uncertain if there are differences in muscle strength at end of the intervention between groups (MD 9.91, 95% CI -3.68 to 23.50; 3 trials, 199 participants; I² = 44%; very low-certainty evidence). One trial measured perceived fatigue using the Checklist Individual Strength (CIST). Participants in the exercise group showed a clinically important lower degree of fatigue perception than participants in the control group, with a mean reduction of 40 points in the CIST (95% CI 15.62 to 64.38; 1 trial, 30 participants).  We identified three ongoing studies.

AUTHORS' CONCLUSIONS

Based on very low-certainty evidence in our systematic review, we are very uncertain of the role of exercise training (aerobic, resistance-based exercises, or both) in affecting mortality, health-related quality of life, and physical function (i.e. aerobic capacity and muscle strength) in liver transplant recipients. There were few data on the composite of cardiovascular mortality and cardiovascular disease, cardiovascular disease post-transplantation, and adverse event outcomes. We lack larger trials with blinded outcome assessment, designed according to the SPIRIT statement and reported according to the CONSORT statement.

Clinically ill patients' experiences of early mobilisation after liver transplantation: a qualitative study using Pender's health promotion model

The aim of this study is to explore the factors influencing early mobilisation behaviours and patients' needs in critically ill patients after liver transplantation (LT). This interview study used phenomenological research, and Pender's health promotion model (HPM) was used to construct the interview guide. With the use of purposeful sampling, a total of 19 critically ill patients who experienced early mobilisation after LT were recruited at three tertiary hospitals in Beijing from August to November 2022. Data were collected through semi-structured interviews and analysed using Colaizzi's seven-step method. Nine themes were categorised into the three domains of Pender's HPM. The first domain was individual characteristics and experiences: (1) symptoms of end-stage liver disease limiting premobility behaviours and (2) previous treatment experience affecting understanding of early mobilisation after LT. The second domain was behaviour-specific cognition and affect: (3) coexistence of benefits and concerns in early mobilisation after LT, (4) barriers to early mobilisation after LT, (5) high self-efficacy in early mobilisation after LT, (6) individual differences in early mobilisation and (7) support and encouragement from family, wardmates and medical staff. The final domain was behavioural outcomes: (8) the need for sufficient staff, a quiet environment, safety, goals, guidance and family participation and (9) a strong willingness to comply with early mobilisation plans. The three areas and nine themes extracted in this study are helpful for the long-term development of early mobilisation in patients after LT.

Clinical Practice Guideline: Early Mobilization and Rehabilitation of Critically Ill Burn Patients

This Clinical Practice Guideline addresses early mobilization and rehabilitation (EMR) of critically ill adult burn patients in an intensive care unit (ICU) setting. We defined EMR as any systematic or protocolized intervention that could include muscle activation, active exercises in bed, active resistance exercises, active side-to-side turning, or mobilization to sitting at the bedside, standing, or walking, including mobilization using assistance with hoists or tilt tables, which was initiated within at least 14 days of injury, while the patient was still in an ICU setting. After developing relevant PICO (Population, Intervention, Comparator, Outcomes) questions, a comprehensive literature search was conducted with the help of a professional medical librarian. Available literature was reviewed and systematically evaluated. Recommendations were formulated through the consensus of a multidisciplinary committee, which included burn nurses, physicians, and rehabilitation therapists, based on the available scientific evidence. No recommendation could be formed on the use of EMR to reduce the duration of mechanical ventilation in the burn ICU, but we conditionally recommend the use of EMR to reduce ICU-acquired weakness in critically ill burn patients. No recommendation could be made regarding EMR's effects on the development of hospital-acquired pressure injuries or disruption or damage to the skin grafts and skin substitutes. We conditionally recommend the use of EMR to reduce delirium in critically ill burn patients in the ICU.

Factors associated with early postoperative exercise tolerance after living-donor liver transplantation

BACKGROUND

Physical dysfunction, including exercise intolerance, is a major factor for delayed societal reintegration for patients who underwent living-donor liver transplantation (LDLT). However, what may contribute to early postoperative physical function is not well known. The purpose of this study is to elucidate the perioperative factors affecting early posttransplant exercise intolerance.

METHODS

103 consecutive patients who underwent LDLT were enrolled, and 68 patients were retrospectively analyzed. We examined the relationship between postoperative exercise tolerance evaluated by a 6-minute walking distance (6MWD) at discharge after surgery and demographic data, surgical information, preoperative physical function, clinical course, and the postoperative decline in physical function with univariate and multivariate analyses.

RESULTS

Almost all patients were discharged within 3 months after surgery. The postoperative 6MWD was 408 ± 94 m (68 [61-84]% of the predicted value), and patients who had a low %6MWD at discharge had significantly lower preoperative physical function than patients who had a high %6MWD at discharge (grip strength: 29.8 ± 8.9 kgf vs. 23.0 ± 8.8 kgf, P < .01, knee extensor strength: 138.9 ± 59.4 Nm vs. 95.2 ± 42.1 Nm, P < .01). Multivariate analysis revealed that preoperative knee extensor strength (standardized β = 0.35, P < .01) and first postoperative walking day (standardized β = -0.22, P = .04) were independently associated with the postoperative %6MWD.

CONCLUSION

These results suggest that maintaining preoperative muscle strength and allowing for early postoperative mobilization might help to enhance the recovery of physical function and facilitate the patient's social reintegration after LDLT.

Attenuating Muscle Mass Loss in Critical Illness: the Role of Nutrition and Exercise

PURPOSE OF REVIEW

Impaired recovery following an intensive care unit (ICU) admission is thought related to muscle wasting. Nutrition and physical activity are considered potential avenues to attenuate muscle wasting. The aim of this review was to present evidence for these interventions in attenuating muscle loss or improving strength and function.

RECENT FINDINGS

Randomised controlled trials on the impact of nutrition or physical activity interventions in critically ill adult patients on muscle mass, strength or function are presented. No nutrition intervention has shown an effect on strength or function, and the effect on muscle mass is conflicting. RCTs on the effect of physical activity demonstrate conflicting results; yet, there is a signal for improved strength and function with higher levels of physical activity, particularly when commenced early. Further research is needed to elucidate the impact of nutrition and physical activity on muscle mass, strength and function, particularly in combination.

New ERAS in liver transplantation - Past, present, and next steps

There are parallels between the history of Enhanced Recovery after Surgery (ERAS) and liver transplantation. Both have been established and advanced by innovative individuals, often going against perceived wisdom and convention. Liver transplantation has traditionally been considered too complex for ERAS pathways, despite a small number of trials showing them to be both safe and of benefit. To date, there are very few randomized controlled trials and cohort studies publishing outcomes on liver transplant patients enrolled in comprehensive ERAS pathways. To progress our field, the 2022 International Liver Transplantation Society's Consensus Conference has created expert panels to analyze the evidence in 32 domains of the liver transplantation pathway using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach to generate expert recommendations. These recommendations will be voted on by the international community to gain consensus using the Danish model, and create the ERAS4OLT.org Enhanced Recovery after Liver Transplantation Pathway.

The role of acute in-patient rehabilitation on short-term outcomes after liver transplantation: A systematic review of the literature and expert panel recommendations

BACKGROUND

The indication and surgical complexity of orthotopic liver transplantation underscore the need for strategies to optimize the recovery for transplant recipients. We conducted a systematic review aimed at identifying, evaluating, and synthesizing the evidence examining the effect of in-patient rehabilitation for liver transplant recipients and provide related practice recommendations.

METHODS

Health research databases were systematically reviewed for studies that included adults who received liver transplantation and participated in acute, post-transplant rehabilitation. Postoperative morbidity, mortality, length of hospital stay, length of intensive care unit stay, and other markers of surgical recovery were extracted. Practice recommendations are provided by an international panel using GRADE.

RESULTS

Twelve studies were included in the review (including 3901 participants). Rehabilitation interventions varied widely in design and composition; however, details regarding intervention delivery were poorly described in general. The quality of evidence was rated as very low largely owing to "very serious" imprecision, poor reporting, and limited data from comparative studies. Overall, the studies suggest that in-patient rehabilitation for recipients of liver transplantation is safe, tolerable, and feasible, and may benefit functional outcomes.

CONCLUSION

Two practice recommendations related to in-patient rehabilitation following LT were yielded from this review: (1) it is safe, tolerable, and feasible; and (2) it improves postoperative functional outcomes. Each of the recommendations are weak and supported by low quality of evidence. No recommendation could be made related to benefits or harms for clinical, physiological, and other outcomes. Adequately powered and high quality randomized controlled trials are urgently needed in this area.

Expert consensus on liver transplantation perioperative evaluation and rehabilitation for acute-on-chronic liver failure

Acute-on-chronic liver failure (ACLF) can be cured by liver transplantation; however, perioperative complications still affect posttransplant outcomes. In recent years, early rehabilitation for critical illness, liver disease, and surgery have significantly improved organ reserve function, surgery tolerance, and postoperative quality of life. They could also be applied in the perioperative period of liver transplantation in patients with ACLF. Therefore, the Transplantation Immunology Committee of Branch of Organ Transplantation Physician of Chinese Medical Doctor Association, the Organ Transplant Committee of China Association Rehabilitation Medicine, and the Guangdong Medical Doctor Association of Organ Transplantation conducted a comprehensive review of rehabilitation in end-stage liver disease, critical illness and surgical patients by summarizing current evidence and best clinical practices and proposed a practice consensus on evaluation of cardiopulmonary and physical function, rehabilitation or physiotherapies, as well as the safety concerns in perioperative liver transplant recipients. It will be a valuable resource for hepatologists, transplant surgeons, and intensivists as they care for ACLF patients during transplantation.

The validity, reliability and feasibility of four instruments for assessing the consciousness of stroke patients in a neurological intensive care unit compared

Background

Early rehabilitation is the foundation for recovery for those admitted to an intensive care unit. Appropriate assessment of consciousness is needed before any rehabilitative intervention begins.

Methods

This prospective study compared the validity, reliability and applicability of the sedation-agitation scale, the Richmond Agitation-Sedation Scale, the motor activity assessment scale and the Glasgow Coma Scale in a working neurological intensive care unit. Eighty-three stroke patients were assessed with the four scales by the same 3 raters acting independently: a senior physician, a senior therapist and a trainee. That generated 996 assessment records for comparison.

Results

Good agreement (r=0.98–0.99) was found among the sedation-agitation scale, the Richmond Agitation-Sedation Scale, the motor activity assessment scale scores, but the Glasgow Coma Scale ratings correlated less well (r=0.72–0.76) with the others. Consistent results were also found among the three raters. After stratification of the ratings by age, gender, level of consciousness and Acute Physiology and Chronic Health Evaluation score, the scales reported significant differences among the levels of consciousness and among those with different Acute Physiology and Chronic Health Evaluation results, but not with different age or gender strata.

Conclusions

The four instruments tested are all reliable enough and feasible for use as a tool for consciousness screening in a neurological intensive care unit.

Guidelines for Perioperative Care for Liver Transplantation: Enhanced Recovery After Surgery (ERAS) Recommendations

BACKGROUND

Enhanced Recovery After Surgery (ERAS) is a multimodal, evidence-based, program of care developed to minimize the response to surgical stress, associated with reduced perioperative morbidity and hospital stay. This study presents the specific ERAS Society recommendations for liver transplantation (LT) based on the best available evidence and on expert consensus.

METHODS

PubMed and ClinicalTrials.gov were searched in April 2019 for published and ongoing randomized clinical trials on LT in the last 15 y. Studies were selected by 5 independent reviewers and were eligible if focusing on each validated ERAS item in the area of adult LT. An e-Delphi method was used with an extended interdisciplinary panel of experts to validate the final recommendations.

RESULTS

Forty-three articles were included in the systematic review. A consensus was reached among experts after the second round. Patients should be screened for malnutrition and treated whenever possible. Prophylactic nasogastric intubation and prophylactic abdominal drainage may be omitted, and early extubation should be considered. Early oral intake, mobilization, and multimodal-balanced analgesia are recommended.

CONCLUSIONS

The current ERAS recommendations were elaborated based on the best available evidence and endorsed by the e-Delphi method. Nevertheless, prospective studies need to confirm the clinical use of the suggested protocol.

Enhanced recovery after surgery programs improve short-term outcomes after liver transplantation - A systematic review and meta-analysis

This systematic review aimed to investigate the available quality of evidence (QOE) of enhanced recovery after surgery (ERAS) for liver transplantation (LT) on short-term outcomes, grade recommendations and identify relevant components for ERAS protocols. A systematic review and meta-analysis were conducted on short-term outcomes after LT when applying comprehensive ERAS protocols (>1 ERAS component) versus control groups (CRD42021210374), following the GRADE approach for grading quality of evidence and strength of recommendations. Endpoints were morbidity, mortality, length of stay and readmission rates after ERAS for LT. Of 858 screened articles, two randomized controlled trials, 2 prospective and 1 retrospective cohort studies were included (2002 - 2020). Frequent ERAS components were early extubation and postoperative antibiotic, fluid and nutrition management. Overall complications were reduced in ERAS versus control cohorts (OR 0.4 (CI 0.2, 0.7), with no significant differences in mortality and hospital readmission rates. Intensive care unit and hospital length of stay were shorter in ERAS groups (percentage decrease, 55% and 29%, respectively). QOE for individual outcomes was rated moderate to low. ERAS protocols in LT are related to improved short-term outcomes after liver transplantation (Quality of Evidence; Moderate to low | Grade of Recommendation; Strong), but currently lack standardization.

Expert consensus on perioperative management of liver transplantation in adults with acute-on-chronic liver failure

Acute-on-chronic liver failure (ACLF) is a syndrome in which acute liver failure with extrahepatic organ failure occurs on chronic liver disease. Recently, liver transplantation is the only effective treatment for ACLF. There is still room for discussion on the optimal surgery timing for ACLF, perioperative infection prevention and control, and maintenance of nutrition and organ function. The Transplantation Immunology Committee of Branch of Organ Transplantation Physician of Chinese Medical Doctor Association and Enhanced Recovery of Liver Transplantation Group of Enhanced Recovery after Surgery Committee of Chinese Research Hospital Association invited relevant experts to discuss the perioperative management of ACLF liver transplantation in areas including surgery timing, organ protection, nutritional support, infection prevention and control, rehabilitation exercises, regulation of the internal environment, etc. An expert consensus was developed as reference for clinicians.

Effects of Rehabilitation Interventions on Clinical Outcomes in Critically Ill Patients: Systematic Review and Meta-Analysis of Randomized Controlled Trials

OBJECTIVES

To assess the impact of rehabilitation in ICU on clinical outcomes.

DATA SOURCES

Secondary data analysis of randomized controlled trials published between 1998 and October 2019 was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

STUDY SELECTION

We have selected trials investigating neuromuscular electrical stimulation or cycling exercises or protocolized physical rehabilitation as compared to standard of care in critically ill adults.

DATA EXTRACTION

Mortality, length of stay in ICU and at hospital, days on mechanical ventilator, and adverse events.

DATA SYNTHESIS

We found 43 randomized controlled trials (nine on cycling, 14 on neuromuscular electrical stimulation alone and 20 on protocolized physical rehabilitation) into which 3,548 patients were randomized and none of whom experienced an intervention-related serious adverse event. The exercise interventions had no influence on mortality (odds ratio 0.94 [0.79-1.12], n = 38 randomized controlled trials) but reduced duration of mechanical ventilation (mean difference, -1.7 d [-2.5 to -0.8 d], n = 32, length of stay in ICU (-1.2 d [-2.5 to 0.0 d], n = 32) but not at hospital (-1.6 [-4.3 to 1.2 d], n = 23). The effects on the length of mechanical ventilation and ICU stay were only significant for the protocolized physical rehabilitation subgroup and enhanced in patients with longer ICU stay and lower Acute Physiology and Chronic Health Evaluation II scores. There was no benefit of early start of the intervention. It is likely that the dose of rehabilitation delivered was much lower than dictated by the protocol in many randomized controlled trials and negative results may reflect the failure to implement the intervention.

CONCLUSIONS

Rehabilitation interventions in critically ill patients do not influence mortality and are safe. Protocolized physical rehabilitation significantly shortens time spent on mechanical ventilation and in ICU, but this does not consistently translate into long-term functional benefit. Stable patients with lower Acute Physiology and Chronic Health Evaluation II at admission (<20) and prone to protracted ICU stay may benefit most from rehabilitation interventions.

Practical model to identify liver transplant recipients at low risk of postoperative haemorrhage, bile leakage and ascites

Background

This study aimed to identify a subgroup of recipients at low risk of haemorrhage, bile leakage and ascites following liver transplantation (LT).

Methods

Factors associated with significant postoperative ascites (more than 10 ml/kg on postoperative day 5), bile leakage and haemorrhage after LT were identified using three separate multivariable analyses in patients who had LT in 2010–2019. A model predicting the absence of all three outcomes was created and validated internally using bootstrap procedure.

Results

Overall, 944 recipients underwent LT. Rates of ascites, bile leakage and haemorrhage were 34.9, 7.7 and 6.0 per cent respectively. The 90-day mortality rate was 7.0 per cent. Partial liver graft (relative risk (RR) 1.31; P = 0.021), intraoperative ascites (more than 10 ml/kg suctioned after laparotomy) (RR 2.05; P = 0.001), malnutrition (RR 1.27; P = 0.006), portal vein thrombosis (RR 1.56; P = 0.024) and intraoperative blood loss greater than 1000 ml (RR 1.39; P = 0.003) were independently associated with postoperative ascites and/or bile leak and/or haemorrhage, and were introduced in the model. The model was well calibrated and predicted the absence of all three outcomes with an area under the curve of 0.76 (P = 0.001). Of the 944 patients, 218 (23.1 per cent) fulfilled the five criteria of the model, and 9.6 per cent experienced postoperative ascites (RR 0.22; P = 0.001), 1.8 per cent haemorrhage (RR 0.21; P = 0.033), 4.1 per cent bile leak (RR 0.54; P = 0.048), 40.4 per cent severe complications (RR 0.70; P = 0.001) and 1.4 per cent 90-day mortality (RR 0.13; P = 0.004).

Conclusion

A practical model has been provided to identify patients at low risk of ascites, bile leakage and haemorrhage after LT; these patients could potentially qualify for inclusion in non-abdominal drainage protocols.

Systematic early versus late mobilization or standard early mobilization in mechanically ventilated adult ICU patients: systematic review and meta-analysis

BACKGROUND

This systematic review and meta-analysis aimed to determine the effectiveness of systematic early mobilization in improving muscle strength and physical function in mechanically ventilated intensive care unit (ICU) patients.

METHODS

We conducted a two-stage systematic literature search in MEDLINE, EMBASE and the Cochrane Library until January 2019 for randomized controlled trials (RCTs) examining the effects of early mobilization initiated within 7 days after ICU admission compared with late mobilization, standard early mobilization or no mobilization. Priority outcomes were Medical Research Council Sum Score (MRC-SS), incidence of ICU-acquired weakness (ICUAW), 6-min walk test (6MWT), proportion of patients reaching independence, time needed until walking, SF-36 Physical Function Domain Score (PFS) and SF-36 Physical Health Component Score (PCS). Meta-analysis was conducted where sufficient comparable evidence was available. We evaluated the certainty of evidence according to the GRADE approach.

RESULTS

We identified 12 eligible RCTs contributing data from 1304 participants. Two RCTs were categorized as comparing systematic early with late mobilization, nine with standard early mobilization and one with no mobilization. We found evidence for a benefit of systematic early mobilization compared to late mobilization for SF-36 PFS (MD 12.3; 95% CI 3.9-20.8) and PCS (MD 3.4; 95% CI 0.01-6.8), as well as on the proportion of patients reaching independence and the time needed to walking, but not for incidence of ICUAW (RR 0.62; 95% CI 0.38-1.03) or MRC-SS. For systematic early compared to standard early mobilization, we found no statistically significant benefit on MRC-SS (MD 5.8; 95% CI - 1.4 to 13.0), incidence of ICUAW (RR 0.90; 95% CI 0.63-1.27), SF-36 PFS (MD 8.1; 95% CI - 15.3 to 31.4) or PCS (MD - 2.4; 95% CI - 6.1 to 1.3) or other priority outcomes except for change in 6MWT from baseline. Generally, effects appeared stronger for systematic early compared to late mobilization than to standard early mobilization. We judged the certainty of evidence for all outcomes as very low to low.

CONCLUSION

The evidence regarding a benefit of systematic early mobilization remained inconclusive. However, our findings indicate that the larger the difference in the timing between the intervention and the comparator, the more likely an RCT is to find a benefit for early mobilization.

Effects of Inspiratory Muscle Training and Early Mobilization on Weaning of Mechanical Ventilation: A Systematic Review and Network Meta-analysis

OBJECTIVE

To compare the effectiveness and rank order of physical therapy interventions, including conventional physical therapy (CPT), inspiratory muscle training (IMT), and early mobilization (EM) on mechanical ventilation (MV) duration and weaning duration.

DATA SOURCES

PubMed, The Cochrane Library, Scopus, and CINAHL complete electronic databases were searched through August 2019.

STUDY SELECTION

Randomized controlled trials (RCTs) investigating the effect of IMT, EM, or CPT on MV duration and the weaning duration in patients with MV were included. Studies that were determined to meet the eligibility criteria by 2 independent authors were included. A total of 6498 relevant studies were identified in the search, and 18 RCTs (934 participants) were included in the final analysis.

DATA EXTRACTION

Data were extracted independently by 2 authors and assessed the study quality by the Cochrane risk-of-bias tool. The primary outcomes were MV duration and weaning duration.

DATA SYNTHESIS

Various interventions of physical therapy were identified in the eligible studies, including IMT, IMT+CPT, EM, EM+CPT, and CPT. The data analysis demonstrated that compared with CPT, IMT+CPT significantly reduced the weaning duration (mean difference; 95% confidence interval) (-2.60; -4.76 to -0.45) and EM significantly reduced the MV duration (-2.01; -3.81 to -0.22). IMT+CPT and EM had the highest effectiveness in reducing the weaning duration and MV duration, respectively.

CONCLUSION

IMT or EM should be recommended for improving the weaning outcomes in mechanically ventilated patients. However, an interpretation with caution is required due to the heterogeneity.

Brazilian Guidelines for Early Mobilization in Intensive Care Unit

Immobility can cause several complications, including skeletal muscle atrophy and weakness, that influence the recovery of critically ill patients. This effect can be mitigated by early mobilization. Six key questions guided this research: Is early mobilization safe? Which patients are candidates for early mobilization? What are the contraindications? What is the appropriate dose, and how should it be defined? What results are obtained? What are the prognostic indicators for the use of early mobilization? The objective of this guideline was to produce a document that would provide evidence-based recommendations and suggestions regarding the early mobilization of critically ill adult patients, with the aim of improving understanding of the topic and making a positive impact on patient care. This guideline was based on a systematic review of articles conducted using the PICO search strategy, as recommended by the Guidelines Project of the Associação Médica Brasileira. Randomized clinical trials, prognostic cohort studies, and systematic reviews with or without meta-analysis were selected, and the evidence was classified according to the Oxford Center for Evidence-based Medicine Levels of Evidence. For all the questions addressed, enough evidence was found to support safe and well-defined early mobilization, with prognostic indicators that support and recommend the technique. Early mobilization is associated with better functional outcomes and should be performed whenever indicated. Early mobilization is safe and should be the goal of the entire multidisciplinary team.

Early versus delayed mobilization for in-hospital mortality and health-related quality of life among critically ill patients: a systematic review and meta-analysis

Background

This systematic review and meta-analysis of randomized clinical trials aimed to investigate the efficacy of early mobilization among critically ill adult patients.

Methods

We searched CENTRAL, MEDLINE, and Igaku-Chuo-Zasshi (a Japanese bibliographic database) databases until April 2019 and included randomized control trials to compare early mobilization started within 1 week of intensive care unit (ICU) admission and earlier-than-usual care with the usual care or mobilization initiated later than the intervention. Two authors independently extracted the data of the included studies and assessed their quality. The primary outcomes were in-hospital mortality, length of ICU/hospital stay, and health-related quality of life (QOL).

Results

Among 1085 titles/abstracts screened, 11 studies (including 1322 patients) were included in the meta-analysis, which was conducted using the random-effects model. The pooled relative risk for in-hospital mortality comparing early mobilization to usual care (control) was 1.12 (95% CI [confidence interval]: 0.80 to 1.58, I ² = 0%). The pooled mean differences for duration of ICU and hospital stay were -1.54 (95% CI: -3.33 to 0.25, I ² = 90%) and -2.86 (95% CI: -5.51 to -0.21, I ² = 85%), respectively. The pooled mean differences at 6 months post-discharge, as measured by the Short Form 36-Item Health Survey and Euro-QOL EQ-5D, were 4.65 (95% CI: -16.13 to 25.43, I ² = 86%) for physical functioning and 0.29 (95% CI: -11.19 to 11.78, I ² = 66%) for the visual analog scale.

Conclusions

Our study indicated no apparent differences between early mobilization and usual care in terms of in-hospital mortality and health-related QOL. Detailed larger studies are warranted to evaluate the impact of early mobilization on in-hospital mortality and health-related QOL in critically ill patients.

Early mobilization of critically ill patients in the intensive care unit: A systematic review and meta-analysis

BACKGROUND

Physical therapy can prevent functional impairments and improve the quality of life of patients after hospital discharge. However, the effect of early mobilization on patients with a critical illness remains unclear. This study was performed to assess the evidence available regarding the effect of early mobilization on critically ill patients in the intensive care unit (ICU).

METHODS

Electronic databases were searched from their inception to March 21, 2019. Randomized controlled trials (RCTs) comprising critically ill patients who received early mobilization were included. The methodological quality and risk of bias of each eligible trial were assessed using the Cochrane Collaboration tool. Data were extracted using a standard collection form each included study, and processed using the Mantel-Haenszel (M-H) or inverse-variance (I-V) test in the STATA v12.0 statistical software.

RESULTS

A total of 1,898 records were screened. Twenty-three RCTs comprising 2,308 critically ill patients were ultimately included. Early mobilization decreased the incidence of ICU-acquired weakness (ICU-AW) at hospital discharge (three studies, 190 patients, relative risk (RR): 0.60, 95% confidence interval (CI) [0.40, 0.90]; p = 0.013, I2 = 0.0%), increased the number of patients who were able to stand (one study, 50 patients, 90% vs. 62%, p = 0.02), increased the number of ventilator-free days (six studies, 745 patients, standardized mean difference (SMD): 0.17, 95% CI [0.02, 0.31]; p = 0.023, I2 = 35.5%) during hospitalization, increased the distance the patient was able to walk unassisted (one study, 104 patients, 33.4 (0-91.4) meters vs. 0 (0-30.4) meters, p = 0.004) at hospital discharge, and increased the discharged-to-home rate (seven studies, 793 patients, RR: 1.16, 95% CI [1.00, 1.34]; p = 0.046). The mortality (28-day, ICU and hospital) and adverse event rates were moderately increased by early mobilization, but the differences were statistically non-significant. However, due to the substantial heterogeneity among the included studies, and the low quality of the evidence, the results of this study should be interpreted with caution. Publication bias was not identified.

CONCLUSIONS

Early mobilization appears to decrease the incidence of ICU-AW, improve the functional capacity, and increase the number of ventilator-free days and the discharged-to-home rate for patients with a critical illness in the ICU setting.

Enhanced Recovery in Liver Transplantation: A Feasibility Study

BACKGROUND

Enhanced Recovery After Surgery (ERAS) programmes after surgery are effective in reducing length of stay, functional recovery and complication rates in liver surgery (LS) with the indirect advantage of reducing hospitalisation costs. Preoperative comorbidities, challenging surgical procedures and complex post-operative management are the points that liver transplantation (LT) shares with LS. Nevertheless, there is little evidence regarding the feasibility and safety of ERAS programmes in LT.

METHODS

We designed a pilot, small-scale, feasibility study to assess the impact on hospital stay, protocol compliance and safety of an ERAS programme tailored for LT. The ERAS arm was compared with a 1:2 match paired control arm with similar characteristics. All patients with MELD <25 were included. A dedicated LT-tailored protocol was derived from publications on ERAS liver surgery.

RESULTS

Ten patients were included in the Fast-Trans arm. It was observed a 47% reduction of the total LOS, as compared to the control arm: 9.5 (9.0-10.5) days versus 18.0 (14.3-24.3) days, respectively, p <0.001. The protocol achieved 72.9% compliance. No differences were observed in terms of post-operative complications or readmission rates after discharge between the two arms. Overall, it was observed a reduction of length of stay in ICU and surgical ward in the Fast-Trans arm compared with the control arm.

CONCLUSION

Considered the main points in common between LS and LT, this small-scale study suggests that the application of an ERAS programme tailored to the LT setting is feasible. Further testing will be appropriate to generalise these findings.

Effects of quadriceps muscle neuromuscular electrical stimulation in living donor liver transplant recipients: phase-II single-blinded randomized controlled trial

OBJECTIVE

To evaluate the efficacy of neuromuscular electrical stimulation on quadriceps muscle strength and thickness in liver transplantation patients.

DESIGN

Phase-II, randomized, parallel-group, allocation-concealed, assessor-blinded, single-center controlled trial.

SETTING

Inpatient rehabilitation sector.

SUBJECTS

Patients following living donor liver transplantation.

INTERVENTIONS

The quadriceps muscle stimulation and the control groups received bilateral muscle electrical stimulation on the quadriceps and tibialis anterior muscles, respectively. Neuromuscular electrical stimulation sessions in both groups were conducted for 30 minutes per session, once per day for five weekdays over four weeks by a physical therapist.

MAIN MEASURES

Quadriceps muscle strength and quadriceps muscle thickness.

RESULTS

Neuromuscular electrical stimulation was applied to the quadriceps muscles group ( n = 23) or the tibialis anterior muscle in the control group ( n = 22). The decrease in quadriceps muscle thickness differed significantly between both groups on postoperative day 30 (median -3 vs -8, P < 0.01). The changes in predicted quadriceps strength and 6 minutes walking distance were not significantly different between groups (quadriceps strength median -12% vs -5%, P = 0.40; 6 minutes walking distance median -18 vs -21 m, P = 0.74).

CONCLUSION

Neuromuscular electrical stimulation of the quadriceps muscle for liver transplantation recipients was able to maintain the quadriceps muscle thickness after surgery. Future larger scale studies are needed to consider the effectiveness of neuromuscular electrical stimulation and how to incorporate this intervention in the overall strategy of the physical therapy program.

Recent evidence on early mobilization in critical-Ill patients

PURPOSE OF REVIEW

To examine the benefits of early mobilization and summarize the results of most recent clinical studies examining early mobilization in critically ill patients followed by a presentation of recent developments in the field.

RECENT FINDINGS

Early mobilization of ICU patients, defined as mobilization within 72 h of ICU admission, is still uncommon. In medical and surgical critically ill patients, mobilization is well tolerated even in intubated patients. In neurocritical care, evidence to support early mobilization is either lacking (aneurysmal subarachnoid hemorrhage), or the results are inconsistent (e.g. stroke). Successful implementation of early mobilization requires a cultural change; preferably based on an interprofessional approach with clearly defined responsibilities and including a mobilization scoring system. Although the evidence for the majority of the technical tools is still limited, the use of a bed cycle ergometer and a treadmill with strap system has been promising in smaller trials.

SUMMARY

Early mobilization is well tolerated and feasible, resulting in improved outcomes in surgical and medical ICU patients. Implementation of early mobilization can be challenging and may need a cultural change anchored in an interprofessional approach and integrated in a patient-centered bundle. Scoring systems should be integrated to define daily goals and used to verify patients' achievements or identify barriers immediately.
