Outpatient-based physical rehabilitation for survivors of prolonged critical illness: A randomized controlled trial

Effect of Home Care on Physical Function in Post-Intensive Care Unit Patients: A Meta-Analysis

BACKGROUND

A decline in physical function is commonly observed after patients transition to their homes following hospital admission; this is especially true for patients requiring mechanical ventilation in an intensive care unit (ICU).

OBJECTIVE

This meta-analysis examines characteristics and effects of home-based or outpatient+home-based interventions used to improve physical function post-discharge in patients who received mechanical ventilation in an ICU.

METHODS

PRISMA guidelines were utilized. The literature search was conducted with the assistance of a medical librarian. Study inclusion criteria were post-ICU adult patients receiving mechanical ventilation who then had home-based or outpatient+home-based care to improve physical function after discharge. Effect size (Hedges' g) was calculated with random effects models.

RESULTS

Our search yielded 11 studies that met the inclusion criteria. The majority were randomized controlled trials, with 1 quasi-experimental study. All studies included physical therapists, and 2 included nurses. The 11 studies reported results for 39 physical function measurements. The overall pooled intervention effect across the 4 studies that utilized the 6-minute walk test was 0.32 (95% confidence intervals [CI]: 0.05 to 0.58), for the 3 studies that utilized the Timed Up and Go test it was 1.38 (95% CI: -0.09 to 2.84), and for the 8 studies that used the SF-36 Physical Function subscale, it was 0.31 (95% CI: 0.09 to 0.52).

CONCLUSIONS

This review's findings show that patients may improve their physical function after participating in specific intervention programs that are home-based alone or outpatient+home-based care. However, the effect sizes are small, so it may be useful to explore how to maximize the gains in physical function.

Muscle Dysfunction and Physical Recovery After Critical Illness

During critical illness, patients experience significant and rapid onsets of muscle wasting and dysfunction with loss of strength, mass, and power. These deficits often persist long after the ICU, leading to impairments in physical function including reduced exercise capacity and increased frailty and disability. While there are numerous studies describing the epidemiology of impaired muscle and physical function in the ICU, there are significantly fewer data investigating mechanisms of prolonged and persistent impairments in ICU survivors. Additionally, while several potential clinical risk factors associated with poor physical recovery have been identified, there remains a dearth of interventions that have effectively improved outcomes long-term among survivors. In this article, we aim to provide a thorough, evidence-based review of the current state of knowledge regarding muscle dysfunction and physical function after critical illness with a focus on post-ICU and post-hospitalization phase of recovery.

Transitioning to a virtual post-intensive care rehabilitation service in response to the COVID-19 pandemic: results of multidisciplinary focus-groups

Background

Telehealth has vastly expanded since the SARS-CoV-2 (COVID-19) pandemic and has been widely implemented as an efficient, cost-effective and accepted means of health care delivery, including rehabilitation. Although telerehabilitation is recommended across national guidelines, there is a lack of practical guidance to support clinicians with virtual adaptations.

Aims

This study aimed to describe the key components of a safe and effective virtual post-intensive-care rehabilitation service, through qualitative exploration.

Methods

This is a qualitative study using a focus-group design based upon grounded theory. This study is nested within a service development project, taking place during the COVID-19 pandemic. Focus groups were held after the first wave of the COVID-19 pandemic with key stakeholders from the physiotherapy and critical care departments of a large tertiary hospital in the United Kingdom. Semi-structured questions were used to guide discussions, led by a facilitator and scribe. Transcripts were thematically analysed using an exploratory inductive approach by two researchers then crosschecked.

Findings

Three focus groups were attended by 12 multidisciplinary stakeholders, including six physiotherapists, two administration staff members, two critical-care follow-up nurses and two critical care consultants. Thematic analysis identified seven critical elements for virtual adaptations: (1) safety and risk assessment, (2) assessment and outcome measures, (3) virtual platform, (4) resources and equipment, (5) exercise programme adaptation, (6) exercise monitoring and safety, and (7) privacy and information governance.

Conclusion

Our findings provide practical recommendations for virtual rehabilitation service development and delivery.

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.

Efficacy of Enhanced Rehabilitation Initiated After Hospital Discharge to Improve Quality of Life in Survivors of Critical Care: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

This systematic review and meta-analysis evaluated the effects of enhanced rehabilitation initiated after hospital discharge on the quality of life (QOL) in survivors of critical care. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) procedure. MEDLINE, CENTRAL, Ichushi, Embase, PEDro, and Cumulated Index to Nursing and Allied Health Literature (CINAHL) databases and the International Clinical Trials Registry Platform and ClinicalTrials.gov (for ongoing or unpublished trials) were searched till January 2024. We identified randomized controlled trials (RCTs) with intensive care unit (ICU) survivors focusing on the effects of enhanced rehabilitation initiated after hospital discharge. Enhanced rehabilitation encompasses protocolized programs offering more intensive, frequent, or longer sessions than standard care. Primary outcomes were physical and mental components of the summary of the standardized QOL scale (SF-36) and adverse events. We calculated pooled-effect estimates for these components, expressing the mean difference (MD) and 95% confidence interval (CI). Risk of bias was evaluated using the Risk of Bias 2 tool. Certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Nine RCTs (573 patients) were included. Enhanced rehabilitation resulted in no difference in the physical component-summary score (two studies: n=79, MD=3.03, 95% CI: -1.37 to 7.43, I2=0%, low-certainty evidence) and a higher mental component-summary score (two studies: n=79, MD=7.27, 95% CI: 2.08-12.46, I2=0%, low-certainty evidence). The evidence on the effect of enhanced rehabilitation on adverse events was very uncertain (nine studies: n=558, risk difference: 0.04, 95% CI: 0.00-0.07, I2=65%, very low-certainty evidence). Seven studies reported no adverse event occurrence, one reported a serious event requiring hospitalization in the intervention group, and another reported a minor event in the intervention group with none in controls. Enhanced rehabilitation initiated after hospital discharge may improve the mental component of QOL for survivors in the critical care. Due to the smaller number of studies included, the results need further confirmation.

The impact of musculoskeletal ill health on quality of life and function after critical care: a multicentre prospective cohort study

Physical disability is a common component of post-intensive care syndrome, but the importance of musculoskeletal health in this population is currently unknown. We aimed to determine the musculoskeletal health state of intensive care unit survivors and assess its relationship with health-related quality of life; employment; and psychological and physical function. We conducted a multicentre prospective cohort study of adults admitted to intensive care for > 48 h without musculoskeletal trauma or neurological insult. Patients were followed up 6 months after admission where musculoskeletal health state was measured using the validated Musculoskeletal Health Questionnaire score. Of the 254 participants, 150 (59%) had a musculoskeletal problem and only 60 (24%) had received physiotherapy after discharge. Functional Comorbidity Index, Clinical Frailty Scale, duration of intensive care unit stay and prone positioning were all independently associated with worse musculoskeletal health. Musculoskeletal health state moderately correlated with quality of life, rs = 0.499 (95%CI 0.392-0.589); anxiety, rs = -0.433 (95%CI -0.538 to -0.315); and depression, rs = -0.537 (95%CI -0.631 to -0.434) (all p < 0.001). Patients with a musculoskeletal problem were less physically active than those without a problem (median (IQR [range]) number of 30 min physical activity sessions per week 1 (0-3.25 [0-7]) vs. 4 (1-7 [0-7]), p < 0.001, respectively). This study found that musculoskeletal health problems were common after intensive care unit stay. However, we observed that < 25% of patients received physical rehabilitation after discharge home. Our work has identified potential high-risk groups to target in future interventional studies.

Effects of exercise interventions on functioning and health-related quality of life following hospital discharge for recovery from critical illness: A systematic review and meta-analysis of randomized trials

OBJECTIVE

This systematic review and meta-analysis aimed to analyze the published randomized controlled trials (RCTs) that investigated the effects of exercise interventions on functioning and health-related quality of life following hospital discharge for recovery from critical illness.

DESIGN

Systematic review and meta-analysis of RCTs.

DATA SOURCES

We searched PubMed/MEDLINE, Cochrane Central Register of Controlled Trials, PEDro data base, and SciELO (from the earliest date available to January 2023) for RCTs that evaluated the effects of physical rehabilitation interventions following hospital discharge for recovery from critical illness.

REVIEW METHODS

Study quality was evaluated using the PEDro Scale. Mean differences (MDs), standard MDs (SMD), and 95% confidence intervals (CIs) were calculated.

RESULTS

Fourteen studies met the study criteria, including 1259 patients. Exercise interventions improved aerobic capacity SMD 0.2 (95% CI: 0.03-0.3, I2 = 0% N = 880, nine studies, high-quality evidence), and physical component score of health-related quality of life MD 3.3 (95% CI: 1.0-5.6, I2 = 57%, six studies N = 669, moderate-quality evidence). In addition, a significant reduction in depression was observed MD -1.4 (95% CI: -2.7 to -0.1, I2 = 0% N = 148, three studies, moderate-quality evidence). No serious adverse events were reported.

CONCLUSION

Exercise intervention was associated with improvement of aerobic capacity, depression, and physical component score of health-related quality of life after hospital discharge for survivors of critical illness.

A randomized clinical trial to evaluate the effect of post-intensive care multidisciplinary consultations on mortality and the quality of life at 1 year

PURPOSE

Critical illness is associated with long-term increased mortality and impaired quality of life (QoL). We assessed whether multidisciplinary consultations would improve outcome at 12 months (M12) after intensive care unit (ICU) discharge.

METHODS

We performed an open, multicenter, parallel-group, randomized clinical trial. Eligible are patients discharged alive from ICU in 11 French hospitals between 2012 and 2018. The intervention group had a multidisciplinary face-to-face consultation involving an intensivist, a psychologist, and a social worker at ICU discharge and then at M3 and M6 (optional). The control group had standard post-ICU follow-up. A consultation was scheduled at M12 for all patients. The QoL was assessed using the EuroQol-5 Dimensions-5 Level (Euro-QoL-5D-5L) which includes five dimensions (mobility, self-care, usual activities, pain, and anxiety/depression), each ranging from 1 to 5 (1: no, 2: slight, 3: moderate, 4: severe, and 5: extreme problems). The primary endpoint was poor clinical outcome defined as death or severe-to-extreme impairment of at least one EuroQoL-5D-5L dimension at M12. The information was collected by a blinded investigator by phone. Secondary outcomes were functional, psychological, and cognitive status at M12 consultation.

RESULTS

540 patients were included (standard, n = 272; multidisciplinary, n = 268). The risk for a poor outcome was significantly greater in the multidisciplinary group than in the standard group [adjusted odds ratio 1.49 (95% confidence interval, (1.04-2.13)]. Seventy-two (13.3%) patients died at M12 (standard, n = 32; multidisciplinary, n = 40). The functional, psychological, and cognitive scores at M12 did not statistically differ between groups.

CONCLUSIONS

A hospital-based, face-to-face, intensivist-led multidisciplinary consultation at ICU discharge then at 3 and 6 months was associated with poor outcome 1 year after ICU.

Models of intensive care unit follow-up care and feasibility of intervention delivery: A systematic review

BACKGROUND

The optimal model of outpatient intensive care unit (ICU) follow-up care remains uncertain, and there is limited evidence of benefit.

RESEARCH QUESTION

The objective of this research is to describe existing models of outpatient ICU follow-up care, quantify participant recruitment and retention, and describe facilitators of patient engagement.

STUDY DESIGN & METHODS

A systematic search of the MEDLINE and EMBASE databases was undertaken in June 2021. Two independent reviewers screened titles, abstracts, and full texts against eligibility criteria. Studies of adults with any outpatient ICU follow-up were included. Studies were excluded if published before 1990, not published in English, or of paediatric patients. Quantitative data were extracted using predefined data fields. Key themes were extracted from qualitative studies. Risk of bias was assessed.

RESULTS

A total of 531 studies were screened. Forty-seven studies (32 quantitative and 15 qualitative studies) with a total of 5998 participants were included. Of 33 quantitative study interventions, the most frequently reported model of care was in-person hospital-based interventions (n = 27), with 10 hybrid (part in-hospital, part remote) interventions. Literature was limited for interventions without hospital attendance (n = 6), including telehealth and diaries. The median ranges of rates of recruitment, rates of intervention delivery, and retention to outcome assessment for hospital-based interventions were 51.5% [24-94%], 61.9% [8-100%], and 52% [8.1-82%], respectively. Rates were higher for interventions without hospital attendance: 82.6% [60-100%], 68.5% [59-89%], and 75% [54-100%]. Facilitators of engagement included patient-perceived value of follow-up, continuity of care, intervention accessibility and flexibility, and follow-up design. Studies had a moderate risk of bias.

INTERPRETATION

Models of post-ICU care without in-person attendance at the index hospital potentially have higher rates of recruitment, intervention delivery success, and increased participant retention when compared to hospital-based interventions.

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.

Follow-up focused on psychological intervention initiated after intensive care unit in adult patients and informal caregivers: a systematic review and meta-analysis

Psychological dysfunction is one of the considerable health-related outcomes among critically-ill patients and their informal caregivers. Follow-up of intensive care unit (ICU) survivors has been conducted in a variety of different ways, with different timing after discharge, targets of interest (physical, psychological, social) and measures used. Of diverse ICU follow-up, the effects of follow-ups which focused on psychological interventions are unknown. Our research question was whether follow-up with patients and their informal caregivers after ICU discharge improved mental health compared to usual care. We published a protocol for this systematic review and meta-analysis in https://www.protocols.io/ (https://dx.doi.org/10.17504/protocols.io.bvjwn4pe). We searched PubMed, Cochrane Library, EMBASE, CINAHL and PsycInfo from their inception to May 2022. We included randomized controlled trials for follow-ups after ICU discharge and focused on psychological intervention for critically ill adult patients and their informal caregivers. We synthesized primary outcomes, including depression, post-traumatic stress disorder (PTSD), and adverse events using the random-effects method. We used the Grading of Recommendations Assessment, Development and Evaluation approach to rate the certainty of evidence. From the 10,471 records, we identified 13 studies (n = 3, 366) focusing on patients and four (n = 538) focusing on informal caregivers. ICU follow-up for patients resulted in little to no difference in the prevalence of depression (RR 0.89, 95% CI [0.59-1.34]; low-certainty evidence) and PTSD (RR 0.84, 95% CI [0.55-1.30]; low-certainty evidence) among patients; however, it increased the prevalence of depression (RR 1.58 95% CI [1.01-2.46]; very low-certainty evidence), PTSD (RR 1.36, 95% CI [0.91-2.03]; very low-certainty evidence) among informal caregivers. The evidence for the effect of ICU follow-up on adverse events among patients was insufficient. Eligible studies for informal caregivers did not define any adverse event. The effect of follow-ups after ICU discharge that focused on psychological intervention should be uncertain.

Post-intensive care syndrome (PICS): recent updates

An increasing number of patients are surviving critical illness, but some experience new or worsening long-lasting impairments in physical, cognitive and/or mental health, commonly known as post-intensive care syndrome (PICS). The need to better understand and improve PICS has resulted in a growing body of literature exploring its various facets. This narrative review will focus on recent studies evaluating various aspects of PICS, including co-occurrence of specific impairments, subtypes/phenotypes, risk factors/mechanisms, and interventions. In addition, we highlight new aspects of PICS, including long-term fatigue, pain, and unemployment.

Post Hospital Discharge Functional Recovery of Critical Illness Survivors. Systematic Review

Background

Millions of people face critical illnesses and need to be hospitalized in an Intensive Care Unit (ICU) annually worldwide. Despite the fact that survival rates of these patients have increased, they develop various cognitive, psychological and functional impairments. This study aims to investigate the significance of the recovery interventions following intensive care unit discharge, the effectiveness of the rehabilitative protocols and their possible deficits.

Methods

MEDLINE (PubMed) and Physiotherapy Evidence Database (PEDro) were searched for studies analyzing the recovery potentials post-ICU among adults, who spent at least 48 hours at the ICU. Methodological quality of the studies was assessed via PEDro Scale.

Results

Nine randomized controlled trials were included. These took place mainly at specialized rehabilitation gyms as well as patients home environments. Studies analyses showed that treatment group showed improvement in functional ability in relation to control group. Nevertheless, differences between two groups were not statistically significant (P<0.05). The majority of studies assessed cardiorespiratory endurance and muscular strength.

Conclusions

The included rehabilitation programs were determined to be effective. Although they didn't prove any statistically significant difference between groups, quality of life enhancements and stress reduction were reported. Hence, new randomized controlled trials are required in order to provide more accurate data on the potential benefits of rehabilitation strategies among post-ICU patients.

Musculoskeletal health state and physical function of intensive care unit survivors: protocol for a UK multicentre prospective cohort study (the MSK-ICU study)

INTRODUCTION

Survivors of critical illness frequently experience long-term physical impairment, decreased health-related quality of life and low rates of return to employment. There has been limited investigation of the underlying problems affecting physical function post-intensive care unit (ICU) admission. Musculoskeletal (MSK) conditions may be complex in presentation, with ICU survivors potentially at greater risk of their development due to the rapid muscle mass loss seen in ICU. The MSK health state of ICU survivors and its impact on physical function remain largely unknown. The aim of the MSK-ICU study is to determine and characterise the MSK health state of ICU survivors 6 months following admission to ICU, in order to inform development of targeted rehabilitation interventions.

METHODS AND ANALYSIS

The MSK-ICU study is a multicentre prospective longitudinal cohort study, evaluating the MSK health state of ICU survivors 6 months after admission to ICU. The study consists of a primary study and two substudies. The primary study will be a telephone follow-up of adults admitted to ICU for more than 48 hours, collecting data on MSK health state, quality of life, employment, anxiety and depression and symptoms of post-traumatic stress disorder. The planned sample size is 334 participants. Multivariable regression will be used to identify prognostic factors for a worse MSK health state, as measured by the MSK-Health Questionnaire. In substudy 1, participants who self-report any MSK problem will undergo a detailed, in-person MSK physical assessment of pain, peripheral joint range of movement and strength. In substudy 2, participants reporting a severe MSK problem will undergo a detailed physical assessment of mobility, function and muscle architecture.

ETHICS AND DISSEMINATION

Ethical approval has been obtained through the North of Scotland Research Ethics Committee 2 (21/NS/0143). We aim to disseminate the findings through international conferences, international peer-reviewed journals and social media.

Musculoskeletal complications following critical illness: A scoping review

PURPOSE

To explore the extent to which musculoskeletal (MSK) complications have been reported following critical illness, identifying evidence gaps and providing recommendations for future research.

MATERIALS AND METHODS

We searched five databases from January 1st 2000 to March 31st 2021. We included published original research reporting MSK complications in patients discharged from hospital following an admission to an intensive care unit (ICU). Two reviewers independently screened English language articles for eligibility. Data extracted included the MSK area of investigation and MSK outcome measures. The overall quality of study was evaluated against standardised reporting guidelines.

RESULTS

4512 titles were screened, and 32 met the inclusion criteria. Only one study included was interventional, with the majority being prospective cohort studies (n = 22). MSK complications identified included: muscle weakness or atrophy, chronic pain, neuromuscular dysfunction, peripheral joint impairment and fracture risk. The quality of the overall reporting in the studies was deemed adequate.

CONCLUSIONS

We identified a heterogenous body of literature reporting a high prevalence of a variety of MSK complications extending beyond muscle weakness, therefore future investigation should include evaluations of more than one MSK area. Further investigation of MSK complications could inform the development of future post critical illness rehabilitation programs.

Application of Nanosystems Synergized by Optics and Chemotherapy in the Treatment of Sports Rehabilitation Diseases

With the rapid development of sports in my country, many athletes will have mild or severe diseases. Physical rehabilitation can improve their physical pain, and some more serious diseases require optical and chemotherapy treatments. This article mainly studies the application of nanosystems that cooperate with optical and chemotherapy in the treatment of sports rehabilitation diseases. In the experiment, the bacteria-infected mice in the wound were divided into 5 groups (n = 4), and the mouse wound model was made. After that, the number of bacteria remaining in the wound was determined by the plate count method. At the same time, a cytotoxicity test was performed, and a control experiment was performed on the cell culture of the polymer at a concentration below the VCR and CMC values. The final sections were used for tissue analysis of serine and epoxy staining. It was found from the experimental data that the cumulative release of free CLB molecules within 3 hours almost reached 100%, and its rapid release was attributed to its small molecular size. In contrast, the release of CLB-HDH micelles in 3 h is 62%, which has a certain relaxation effect. The results showed that CLB-HDH micelles significantly inhibited tumor growth, had good safety in vivo, and had low systemic toxicity. CLB-HDH micelles provide new ideas for efficient CLB tumor treatment.

Does enhanced physical rehabilitation following intensive care unit discharge improve outcomes in patients who received mechanical ventilation? A systematic review and meta-analysis

OBJECTIVE

We aimed to determine whether enhanced physical rehabilitation following intensive care unit (ICU) discharge improves activities-of-daily-living function, quality of life (QOL) and mortality among patients who received mechanical ventilation in the ICU.

DESIGN

Systematic review and meta-analysis using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

DATA SOURCES

MEDLINE, Embase, CENTRAL, PEDro and WHO International Clinical Trials Registry Platform searched through January 2019.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

We included randomised controlled trials assessing the effect of post-ICU rehabilitation designed to either commence earlier and/or be more intensive than the protocol employed in the control group. Only adults who received mechanical ventilation for >24 hours were included.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers extracted data and assessed risk of bias. Standard mean differences (SMDs) with 95% CIs were calculated for QOL, and pooled risk ratios (RRs) with 95% CIs are provided for mortality. We assessed heterogeneity based on I² and the certainty of evidence based on the GRADE approach.

RESULTS

Ten trials (enrolling 1110 patients) compared physical rehabilitation with usual care or no intervention after ICU discharge. Regarding QOL, the SMD (95% CI) between the intervention and control groups for the physical and mental component summary scores was 0.06 (-0.12 to 0.24) and -0.04 (-0.20 to 0.11), respectively. Rehabilitation did not significantly decrease long-term mortality (RR 1.05, 95% CI 0.66 to 1.66). The analysed trials did not report activities-of-daily-living data. The certainty of the evidence for QOL and mortality was moderate.

CONCLUSIONS

Enhanced physical rehabilitation following ICU discharge may make little or no difference to QOL or mortality among patients who received mechanical ventilation in the ICU. Given the wide CIs, further studies are needed to confirm the efficacy of intensive post-ICU rehabilitation in selected populations.

Patients' Perceptions of an Exercise Program Delivered Following Discharge From Hospital After Critical Illness (the Revive Trial)

BACKGROUND

The REVIVE randomized controlled trial (RCT) investigated the effectiveness of an individually tailored (personalized) exercise program for patients discharged from hospital after critical illness. By including qualitative methods, we aimed to explore patients' perceptions of engaging in the exercise program.

METHODS

Patients were recruited from general intensive care units in 6 hospitals in Northern Ireland. Patients allocated to the exercise intervention group were invited to participate in this qualitative study. Independent semistructured interviews were conducted at 6 months after randomization. Interviews were audio-recorded, transcribed, and content analysis used to explore themes arising from the data.

RESULTS

Of 30 patients allocated to the exercise group, 21 completed the interviews. Patients provided insight into the physical and mental sequelae they experienced following critical illness. There was a strong sense of patients' need for the exercise program and its importance for their recovery following discharge home. Key facilitators of the intervention included supervision, tailoring of the exercises to personal needs, and the exercise manual. Barriers included poor mental health, existing physical limitations, and lack of motivation. Patients' views of outcome measures in the REVIVE RCT varied. Many patients were unsure about what would be the best way of measuring how the program affected their health.

CONCLUSIONS

This qualitative study adds an important perspective on patients' attitude to an exercise intervention following recovery from critical illness, and provides insight into the potential facilitators and barriers to delivery of the program and how programs should be evolved for future trials.

Telerehabilitation Solution Conceptual Paper for Community-Based Exercise Rehabilitation of Patients Discharged After Critical Illness

A novel service oriented platform has been developed under the framework of the Telerehabilitation Service funded by the Cross Border Cooperation Programme Greece Cyprus 2007 – 2013 to support tele-supervised exercise rehabilitation for patients after hospitalization in intensive care units (ICU). The platform enables multiparty, interregional bidirectional audio/visual communication between clinical practitioners and post-ICU patients. It also enables patient group-based vital sign real time monitoring, patients’ clinical record bookkeeping, and individualized and group-based patient online exercise programs. The exercise programs intended for the service are based on successful cardiorespiratory rehabilitation programs, individualized and monitored by a multidisciplinary team. The eligibility study of former ICU patients to participate in such a service as well as a cost benefit analysis are presented to support the cost effectiveness of the telerehabilitation program in addition to the expected health benefits to a large proportion of former ICU patients.
