Recovery from Sepsis: Management beyond Acute Care

Recovery from sepsis is a key global health issue, impacting 38 million sepsis survivors worldwide per year. Sepsis survivors face a wide range of physical, cognitive, and psychosocial sequelae. Readmissions to hospital following sepsis are an important driver of global healthcare utilization and cost. Family members of sepsis survivors also experience significant stressors related to their role as informal caregivers. Increasing recognition of the burdens of sepsis survivorship has led to the development of postsepsis recovery programs to better support survivors and their families, although optimal models of care remain uncertain. The goal of this article is to perform a narrative review of recovery from sepsis from the perspective of patients, families, and health systems.

Progress on the Effects of Permissive Hypercapnia on the CNS During the Intraoperative Period: A Narrative Review

Previous experimental findings and clinical evidence have shown the important role of carbon dioxide (CO2) in regulating cerebral vascular tension. CO2 can affect the CNS through various mechanisms. With factors such as patient physiology or surgical interventions potentially causing increased arterial partial pressure of carbon dioxide (PaCO2) levels during mechanical ventilation in general anesthesia, it is important to explore the potential risks or benefits of intraoperative permissive hypercapnia on brain function. In November 2023, we conducted a thorough review of PubMed to establish the article outline. Articles that were non-English or repetitive were eliminated. We collected information on the year, topic, key findings, and opinions of each article. This review not only comprehensively summarizes the factors that contribute to the elevation of intraoperative PaCO2, but also explores the impact of fluctuations in PaCO2 levels on the CNS and the underlying mechanisms involved. At the same time, this article provides our understanding of the potential clinical significance of actively regulating PaCO2 levels. In addition, we propose that the aspects of permissive hypercapnia can be further studied to provide a reliable basis for clinical decision-making. The effects of permissive hypercapnia on the CNS remain a topic of debate. Further prospective randomized controlled studies are needed to determine if permissive hypercapnia can be safely promoted during mechanical ventilation in general anesthesia.

Impact of Protein Intake after Intensive Care Unit on Discharge Destination for Critically Ill Patients: A Single-Center Prospective Observational Study

INTRODUCTION

Although nutritional therapy may be able to enable intensive care unit (ICU) survivors to return home instead of being discharged to a rehabilitation facility, post-ICU discharge nutritional therapy lacks investigation. This study evaluated the impact of nutritional therapy after ICU on discharge destination in critically ill patients.

METHODS

We enrolled consecutive adult patients who spent >72 h in the ICU from December 2020 to March 2023. The primary outcome was discharge destination. Energy and protein intake during the ICU stay and on days 7 and 14 after ICU discharge were evaluated. The target protein intake during the intensive treatment and general ward phases were 0.8 and 1.0 g/kg/day, respectively. Patients were categorized into home discharge (group A) and rehabilitation transfer (group B) groups. Factors affecting the discharge destination were evaluated using logistic regression analysis.

RESULTS

Of the 183 patients included, 134 belonged to group A and 49 to group B. In group A, more patients reached the protein intake target than in group B. Logistic regression analysis identified achieving the protein intake target as an independent predictor of home discharge.

CONCLUSION

Further studies are required to confirm the relationship between nutritional therapy during general ward and patient outcomes.

The Role of Mechanistic Biomarkers in Understanding Acetaminophen Hepatotoxicity in Humans

Our understanding of the fundamental molecular mechanisms of acetaminophen (APAP) hepatotoxicity began in 1973 to 1974, when investigators at the US National Institutes of Health published seminal studies demonstrating conversion of APAP to a reactive metabolite that depletes glutathione and binds to proteins in the liver in mice after overdose. Since then, additional groundbreaking experiments have demonstrated critical roles for mitochondrial damage, oxidative stress, nuclear DNA fragmentation, and necrotic cell death as well. Over the years, some investigators have also attempted to translate these mechanisms to humans using human specimens from APAP overdose patients. This review presents those studies and summarizes what we have learned about APAP hepatotoxicity in humans so far. Overall, the mechanisms of APAP hepatotoxicity in humans strongly resemble those discovered in experimental mouse and cultured hepatocyte models, and emerging biomarkers also suggest similarities in liver repair. The data not only validate the first mechanistic studies of APAP-induced liver injury performed 50 years ago but also demonstrate the human relevance of numerous studies conducted since then. SIGNIFICANCE STATEMENT: Human studies using novel translational, mechanistic biomarkers have confirmed that the fundamental mechanisms of acetaminophen (APAP) hepatotoxicity discovered in rodent models since 1973 are the same in humans. Importantly, these findings have guided the development and understanding of treatments such as N-acetyl-l-cysteine and 4-methylpyrazole over the years. Additional research may improve not only our understanding of APAP overdose pathophysiology in humans but also our ability to predict and treat serious liver injury in patients.

In vivo effects of balanced, low molecular 6% and 10% hydroxyethyl starch compared with crystalloid volume replacement on the coagulation system in major pancreatic surgery-a sub-analysis of a prospective double-blinded, randomized controlled trial

BACKGROUND

The outcome of patients undergoing major surgery treated with HES for hemodynamic optimization is unclear. This post-hoc analysis of a randomized clinical pilot trial investigated the impact of low-molecular balanced HES solutions on the coagulation system, blood loss and transfusion requirements.

METHODS

The Trial was registered: EudraCT 2008-004175-22 and ethical approval was provided by the ethics committee of Berlin. Patients were randomized into three groups receiving either a 10% HES 130/0.42 solution, a 6% HES 130/0.42 solution or a crystalloid following a goal-directed hemodynamic algorithm. Endpoints were parameters of standard and viscoelastic coagulation laboratory, blood loss and transfusion requirements at baseline, at the end of surgery (EOS) and the first postoperative day (POD 1).

RESULTS

Fifty-two patients were included in the analysis (HES 10% (n = 15), HES 6% (n = 17) and crystalloid (n = 20)). Fibrinogen decreased in all groups at EOS (HES 10% 338 [298;378] to 192 [163;234] mg dl-1, p<0.01, HES 6% 385 [302;442] to 174 [163;224] mg dl-1, p<0.01, crystalloids 408 [325;458] to 313 [248;370] mg dl-1, p = 0.01). MCF FIBTEM was decreased for both HES groups at EOS (HES 10%: 20.5 [16.0;24.8] to 6.5 [5.0;10.8] mm, p = <0.01; HES 6% 27.0 [18.8;35.2] to 7.0 [5.0;19.0] mm, p = <0.01). These changes did not persist on POD 1 for HES 10% (rise to 16.0 [13.0;24.0] mm, p = 0.88). Blood loss was not different in the groups nor transfusion requirements.

CONCLUSION

Our data suggest a stronger but transient effect of balanced, low-molecular HES on the coagulation system. Despite the decline of the use of artificial colloids in clinical practice, these results may help to inform clinicians who use HES solutions.

Predictive Factors for Physiotherapy Session Length at an Adult Intensive Care Unit: A Longitudinal Panel Study

OBJECTIVE

To identify predictive factors for the length of physiotherapy sessions for adult intensive care unit (ICU) patients.

DESIGN

Longitudinal panel study.

SETTING

ICU of a secondary-care public teaching hospital, the University Hospital at the University of Sao Paulo, Brazil.

PARTICIPANTS

Medical and surgical patients who received physiotherapy (N=181) assessed in 339 physiotherapy sessions.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The study investigator followed physiotherapists during their work shift and timed the physiotherapy session's length with a stopwatch. The association between session length and patient, physiotherapist, and service-related factors was evaluated by a mixed model.

RESULTS

Assessed in this study were 339 physiotherapy sessions during 79 periods of observation that involved 181 patients and 19 physiotherapists. Median session length was 29 (interquartile range: 22.6-38.9) minutes; median number of patients assisted per physiotherapist per 6-hour shift was 5 (4-5). Physiotherapist's median age was 35 (26-39) years old, and median ICU experience was 13.0 (0.4-16.0) years. Patients were mostly older adults who were post surgery and had been at the ICU for 5 (2-9) days. Factors associated with physiotherapy session length (min) were the following: performing both motor- and respiratory-related physiotherapy procedures during the session (β=6.5; 95% confidence interval [CI], 3.8-9.2), altered chest x-ray (β=2.8; 95% CI, 0.3-5.3), ICU mobility scale (IMS) (β=1.2; 95% CI, 0.4-2.0), contraindication to any level of out-of-bed mobilization (β=-6.9; 95% CI, -10.5 to -3.3), afternoon shift (β=-4.0; 95% CI, -6.7 to -1.4), and Barthel index (β=-0.2; 95% CI, -0.3 to -0.1).

CONCLUSIONS

The factors associated with longer session lengths were performing both motor- and respiratory-related physiotherapy procedures during the session, altered chest x-ray, and the IMS. Contraindication to any level of out-of-bed mobilization and sessions performed during the afternoon shift (vs the morning shift) were associated with shorter session lengths.

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.

Clinical Outcomes of Early vs. Late Tracheostomy in Ventilated COVID-19 Patients

Background The coronavirus disease 2019 (COVID-19) global pandemic prompted a significant use of intensive care resources for managing hypoxic respiratory failure. A substantial portion of these patients required mechanical ventilation. While intubation is common, its impact on mortality improvement has been questionable. Tracheostomies have become crucial for patients needing prolonged ventilation. However, tracheostomies also risk infections, ranging from early-stage mild cellulitis to later-stage nosocomial pneumonia. Our study evaluates the incidence of bacterial infections in COVID-19 patients who underwent tracheostomy early (within 14 days) versus late (more than 14 days after initiation of mechanical ventilation) during their stay in the intensive care unit (ICU). Methods We conducted a retrospective single-center study at Royal Medical Services Military Hospital. The study included COVID-19 patients who underwent tracheostomy and were admitted to the ICU from March 2020 to March 2022. We analyzed the incidence of ventilator-associated pneumonia, the timing of weaning from mechanical ventilation, and outcomes between early and late tracheostomized patients. Analyzed variables included demographics, comorbidities, use of steroids, tocilizumab, inflammation parameters, tracheostomy timing, incidence of bacterial infections, complications, and outcomes. Results The study comprised 36 patients. We found no statistically significant difference in the incidence of bacterial infections between the early and late tracheostomy groups (P>0.05). Complications and overall outcomes did not show significant statistical associations. Inotropes use was more frequent in the late tracheostomy group (P=0.122). In contrast, continuous renal replacement therapy was higher in the early tracheostomy group, showing no significant association (P>0.05). Mortality was higher in the early tracheostomy group, with nine deaths compared to seven in the late tracheostomy group. Interestingly, infection with Acinetobacter baumannii was associated with a statistically significant lower mortality rate, with 75% survival following tracheostomy. Conclusions Findings suggest that tracheostomy timing does not significantly impact the incidence of bacterial pneumonia or other complications, such as the use of inotropes, continuous renal replacement therapy, or mortality rates. These results support the use of personalized decision-making while conducting tracheostomies. Further research is necessary to determine the impacts of tracheostomy timing on patient outcomes more definitively.

Limited Generalizability of Retrospective Single-Center Cohort Study in Comparison to Multicenter Cohort Study on Prognosis of Hepatocellular Carcinoma

Introduction

We aimed to evaluate the generalizability of retrospective single-center cohort studies on prognosis of hepatocellular carcinoma (HCC) by comparing overall survival (OS) after various treatments between a nationwide multicenter cohort and a single-center cohort of HCC patients.

Methods

Patients newly diagnosed with HCC between January 2008 and December 2018 were analyzed using data from the Korean Primary Liver Cancer Registry (multicenter cohort, n=16,443), and the Asan Medical Center HCC registry (single-center cohort, n=15,655). The primary outcome, OS after initial treatment, was compared between the two cohorts for both the entire population and for subcohorts with Child-Pugh A liver function (n=2797 and n=5151, respectively) treated according to the Barcelona-Clinic-Liver-Cancer (BCLC) strategy, using Log rank test and Cox proportional hazard models.

Results

Patients of BCLC stages 0 and A (59.3% vs 35.2%) and patients who received curative treatment (42.1% vs 32.1%) were more frequently observed in the single-center cohort (Ps<0.001). Multivariable analysis revealed significant differences between the two cohorts in OS according to type of treatment: the multicenter cohort was associated with higher risk of mortality among patients who received curative (adjusted hazard ratio [95% confidence interval], 1.48 [1.39-1.59]) and non-curative (1.22 [1.17-1.27]) treatments, whereas the risk was lower in patients treated with systemic therapy (0.83 [0.74-0.92]) and best supportive care (0.85 [0.79-0.91]). Subcohort analysis also demonstrated significantly different OS between the two cohorts, with a higher risk of mortality in multicenter cohort patients who received chemoembolization (1.72 [1.48-2.00]) and ablation (1.44 [1.08-1.92]).

Conclusion

Comparisons of single-center and multicenter cohorts of HCC patients revealed significant differences in OS according to treatment modality after adjustment for prognostic variables. Therefore, the results of retrospective single-center cohort studies of HCC treatments may not be generalizable to real-world practice.

Validation of a Novel Mobile Application for Assessing Pediatric Tracheostomy Emergency Simulations

Objective

Pediatric tracheostomy is associated with high morbidity and mortality, yet clinician knowledge and quality of tracheostomy care may vary widely. In situ simulation is effective at detecting and mitigating related latent safety threats, but evaluation via retrospective video review has disadvantages (eg, delayed analysis, and potential data loss). We evaluated whether a novel mobile application is accurate and reliable for assessment of in situ tracheostomy emergency simulations.

Methods

A novel mobile application was developed for assessment of tracheostomy emergency in situ simulation team performance. After 1.25 hours of training, 6 raters scored 10 tracheostomy emergency simulation videos for the occurrence and timing of 12 critical steps. To assess accuracy, rater scores were compared to a reference standard to determine agreement for occurrence or absence of critical steps and a timestamp within ±5 seconds. Interrater reliability was determined through Cohen's and Fleiss' kappa and intraclass correlation coefficient.

Results

Raters had 86.0% agreement with the reference standard when considering step occurrence and timing, and 92.8% agreement when considering only occurrence. The average timestamp difference from the reference standard was 1.3 ± 18.5 seconds. Overall interrater reliability was almost perfect for both step occurrence (Fleiss' kappa of 0.81) and timing of step (intraclass correlation coefficient of 0.99).

Discussion

Using our novel mobile application, raters with minimal training accurately and reliably assessed videos of tracheostomy emergency simulations and identified areas for future refinement.

Implications for Practice

With refinements, this innovative mobile application is an effective tool for real-time data capture of time-critical steps in in situ tracheostomy emergency simulations.

Quality Improvement Project Reducing Sputum Cultures for Pediatric Patients With a Tracheostomy

BACKGROUND AND OBJECTIVES

Current research implies overuse of diagnostic testing and overtreatment in children with tracheostomies. There are no guidelines for obtaining sputum cultures for these patients, yet they are commonly obtained without significantly affecting management or outcomes. The aim of our quality improvement project was to decrease rate of sputum cultures in this population by 50%, from 64% to 32%.

METHODS

This was a single-center quality improvement project conducted in a pediatric emergency department (ED). Key drivers included: Standardized decision-making, appropriate culture collection, knowledge regarding colonization versus clinically relevant growth, and viral versus bacterial infections in this population. The study team developed an algorithm, used modification to electronic medical records orders, and provided education to drive change. Six months of preintervention and 12 months postintervention data were collected. Run charts/statistical process charts were created for the rate of cultures, length of stay, and return to the ED.

RESULTS

There were 159 patient encounters and the rate of sputum cultures decreased from 64% at baseline to 25% without change in length of stay or increased rate at which patients returned to the ED, including during local coronavirus disease 2019 and respiratory syncytial virus surges. We observed nonrandom data patterns after introduction of algorithm resulting in centerline shifts.

CONCLUSIONS

The study team was able to introduce an algorithm coinciding with a reduction in number of sputum cultures obtained. Next steps would be determining safety and efficacy of such an algorithm over a larger population.

Acute liver failure: Management update and prognosis

Acute liver failure is a rare but serious syndrome, with an incidence of approximately 2,000 to 3,000 cases per year in North America. Its pathophysiology and clinical course vary, depending on the cause of the primary liver injury, and can lead to high morbidity and mortality or the need for liver transplantation, despite available therapies. This syndrome involves excessive activation of the immune system, with damage in other organs, contributing to its high mortality rate. The most accepted definition includes liver injury with hepatic encephalopathy and coagulopathy within the past 26 weeks in a patient with no previous liver disease. The main causes are paracetamol poisoning, viral hepatitis, and drug-induced liver injury, among others. Identifying the cause is crucial, given that it influences prognosis and treatment. Survival has improved with supportive measures, intensive therapy, complication prevention, and the use of medications, such as N-acetylcysteine. Liver transplantation is a curative option for nonresponders to medical treatment, but adequate evaluation of transplantation timing is vital for improving results. Factors such as patient age, underlying cause, and severity of organ failure influence the post-transplant outcomes and survival.

Early In-Bed Cycle Ergometry in Mechanically Ventilated Patients

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

The impact of early rehabilitation in intensive care unit for COVID-19 patients

PURPOSE

To evaluate the impact of early rehabilitation in intensive care unit (ICU) on the survival and functional outcomes of COVID-19 patients admitted to ICU at acute phase.

MATERIALS AND METHODS

We conducted a prospective quasi-experimental study including 346 eligible COVID-19 patients from all admitted cases in an ICU in Vietnam, divided into three groups: no rehabilitation (n = 32), late rehabilitation (n = 109), and early rehabilitation (n = 205). Baseline characteristics and survival information of patient were collected with BORG-CR10 scale and PFIT; the data were collected at different time points: before intervention, when switching to oxygen-therapy, and at discharge.

RESULTS

The control group (patients not using rehabilitation therapy) has worse survival than both early rehabilitation group (hazard ratio [HR] 0.553; 95% confidence interval [CI] 0.380-0.806; p value < 0.001) and late rehabilitation group (HR 0.374; CI 0.235-0.594; p value < 0.001). Regarding functional improvement, during the first five days, rehabilitation did not make a significant impact on the patients (p value > 0.05), however if continued from day 5 to day 20, the early-rehabilitation patients obtained a statistically significant improvement for BORG-CR10 (p value < 0.01). No clear association was found for PFIT (p value > 0.05).

CONCLUSION

The research emphasises the benefits of the early rehabilitation in ICU for COVID-19 patients.

Safety and feasibility of a functional electrical stimulation cycling-based muscular dysfunction diagnostic method in mechanically ventilated patients

BACKGROUND

A nonvolitional diagnostic method based on FES-Cycling technology has recently been demonstrated for mechanically ventilated patients. This method presents good sensitivity and specificity for detecting muscle dysfunction and survival prognosis, even in unconscious patients. As the clinical relevance of this method has already been reported, we aimed to evaluate its safety and feasibility.

METHODS

An observational prospective study was carried out with 20 critically ill, mechanically ventilated patients. The FES-cycling equipment was set in a specific diagnostic mode. For safety determination, hemodynamic parameters and peripheral oxygen saturation were measured before and immediately after the diagnostic protocol, as well as venous oxygen saturation and blood lactate. The creatine phosphokinase level (CPK) was measured before and 24, 48, and 72 h after the test. The time taken to carry out the entire diagnostic protocol and the number of patients with visible muscle contraction (capacity of perceptive muscular recruitment) were recorded to assess feasibility.

RESULTS

Heart rate [91 ± 23 vs. 94 ± 23 bpm (p = 0.0837)], systolic [122 ± 19 vs. 124 ± 19 mm Hg (p = 0.4261)] and diastolic blood pressure [68 ± 13 vs. 70 ± 15 mm Hg (p = 0.3462)], and peripheral [98 (96-99) vs. 98 (95-99) % (p = 0.6353)] and venous oxygen saturation [71 ± 14 vs. 69 ± 14% (p = 0.1317)] did not change after the diagnostic protocol. Moreover, blood lactate [1.48 ± 0.65 vs. 1.53 ± 0.71 mmol/L (p = 0.2320)] did not change. CPK did not change up to 72 h after the test [99 (59-422) vs. 125 (66-674) (p = 0.2799) vs. 161 (66-352) (p > 0.999) vs. 100 (33-409) (p = 0.5901)]. The time taken to perform the diagnostic assessment was 11.3 ± 1.1 min. In addition, 75% of the patients presented very visible muscle contractions, and 25% of them presented barely visible muscle contractions.

CONCLUSIONS

The FES cycling-based muscular dysfunction diagnostic method is safe and feasible. Hemodynamic parameters, peripheral oxygen saturation, venous oxygen saturation, and blood lactate did not change after the diagnostic protocol. The muscle damage marker (CPK) did not increase up to 72 h after the diagnostic protocol.

A Simulated Tracheostomy Tube Change Educational Intervention to Promote Competency Among Novice Healthcare Professionals: A Repeated Measures Study

Objective

To evaluate an educational intervention to promote confidence, knowledge, and skills in tracheostomy tube change among nursing students.

Methods

The study, conducted at the at the Johns Hopkins Center for Immersive Learning and Digital Innovation, enrolled nursing students without prior experience in tracheostomy tube change. The intervention included a pre-recorded presentation, faculty demonstrations with a Tracheostomy Care Training Simulation Model, and participant practice demonstrating skills. Primary outcomes included confidence, knowledge, and competency with tracheostomy tube changes. Secondary outcomes included number of attempts required to achieve competency and time required per attempt. The study followed STROBE guidelines with repeated measure design.

Results

Participants in the study (n=50) had a mean age of 30 years, were predominantly female (83%) with a bachelor's degree (76%), most often in the third semester of nursing school (45%). Participants showed a mean improvement of 3.58 points out of five (SD: 0.56, P<0.001) across 11 pre- and post-test items. Every confidence assessment improved, with the largest increase in assessing tube placement. Knowledge assessments improved across all eight test items in the first test-retest interval, showing an improvement of 1.14 points out of five (SD: 0.89, P<0.001). Competency assessment improved in the first test-retest interval of 1.01 points out of five (SD: 0.65, P<0.001). On serial assessments, time to complete tracheostomy tube change decreased from 2.39 to 0.60 minutes. Faculty deemed 95% of participants competent after only one skill testing iteration.

Conclusion

An educational intervention, combining digital presentations with interactive faculty-led simulations and practical skill assessments, successfully elevated nursing students' confidence, knowledge, and competency in tracheostomy tube changes.

Elevating Tracheostomy Care Through Data-Driven Innovation: What Can Education, Evidence-Based Practice, and Quality Improvement Learn from One Another?

The past decade has witnessed unprecedented progress in tracheostomy care, through communication, dissemination, and implementation of key drivers including interprofessional education, team-based care, standardized protocols, patient and family engagement, and data-driven practice. Improved safety, efficiency, and quality of tracheostomy care reflects contributions from fields of competency-based education, evidence-based practice, and quality improvement. These elements are interconnected, reinforcing one another to enhance patient care. Competency-based interactive education emphasizes active and practical learning through simulations and case studies, which enhance the clinical skills essential for high-quality care. These educational strategies are grounded in clinical research, ensuring that care practices are continually updated and aligned with the latest evidence, thereby bridging the gap between research findings and clinical application. Quality improvement processes such as Plan-Do-Study-Act (PDSA) cycles refine care delivery in real-world settings. Implementation science promotes the uptake of evidence-based practices, ensuring that discoveries translate to improved health outcomes, quality of care, and overall system performance. In each of these domains, patient and family engagement ensures alignment with patient needs and values. The Global Tracheostomy Collaborative leverages this integrated approach through international educational symposia and webinars, comprehensive data analyses, and a learning community that promotes innovative technologies like in situ simulation and augmented and virtual reality. Together, these approaches enhance the learning and application of best practices in tracheostomy care. The continuous, dynamic interaction of education, research, and quality improvement, grounded in patient-centered care, fosters excellence and innovation in care of patients with tracheostomy.

Is comorbidity alone responsible for changes in health-related quality of life among critical care survivors? A purpose-specific review

BACKGROUND

Health-related quality of life (HRQoL) is one of the most important outcome variables for assessing the effectiveness of intensive care, together with mortality and survival, where comorbidity is suggested to have high impact. However, studies are lacking that examine to what extent HRQoL is affected after a general ICU period, beyond that of the effects that may be claimed to be due to comorbidities.

DESIGN

Purpose-specific literature review including literature searches in PubMed, Cinahl, Scopus, and Cochrane library between 2010 and 2021.

MEASUREMENTS AND RESULTS

This Purpose-specific, i.e., task focused review examines HRQoL (assessed by either SF-36 or EQ-5D, > 30 days after leaving the hospital) in adult patients (≥ 18 years) having an ICU length of stay > 24 h. Further, the HRQoL comparisons were adjusted for age or comorbidity. A total of 11 publications were found. A majority comprised observational, prospective cohort studies, except three that were either case-control, cross-sectional comparison, or retrospective cohort studies. A total of 18,566 critically ill patients were included, and the response rate ranged from 16 to 94%. In all studies, a recurrent relevant finding was that HRQoL after ICU care was affected by pre-ICU comorbidities. In three studies (n = 3), which included a comorbidity adjusted control group, there were no effect of the critical care period itself on the registered HRQoL after the critical care period.

CONCLUSION

Health-Related Quality of Life (HRQoL) in former ICU patients appears to be primarily influenced by comorbidity. A notable limitation in this field of research is the high heterogeneity observed in the studies reviewed, particularly in terms of the HRQoL measurement tool employed, the duration of follow-up, the methodology for comorbidity assessment, and the adjustments for age and sex. Despite these variations and the limited number of studies in the review, the findings suggest a minimal HRQoL impact beyond the effects of comorbidity. Given the significant dearth of comprehensive studies in this domain, there is an escalating call for more thorough and detailed research endeavours.

Safety and Feasibility of Neuromuscular Electrical Stimulation in Patients with Extracorporeal Membrane Oxygenation

Background/Objectives: The aim of this study was to investigate the feasibility and safety of neuromuscular electrical stimulation (NMES) in patients on extracorporeal membrane oxygenation (ECMO) and thoroughly assess any potential adverse events. Methods: We conducted a prospective observational study assessing safety and feasibility, including 16 ICU patients on ECMO support who were admitted to the cardiac surgery ICU from January 2022 to December 2023. The majority of patients were females (63%) on veno-arterial (VA)-ECMO (81%), while the main cause was cardiogenic shock (81%) compared to respiratory failure. Patients underwent a 45 min NMES session while on ECMO support that included a warm-up phase of 5 min, a main phase of 35 min, and a recovery phase of 5 min. NMES was implemented on vastus lateralis, vastus medialis, gastrocnemius, and peroneus longus muscles of both lower extremities. Two stimulators delivered biphasic, symmetric impulses of 75 Hz, with a 400 μsec pulse duration, 5 sec on (1.6 sec ramp up and 0.8 sec ramp down) and 21 sec off. The intensity levels aimed to cause visible contractions and be well tolerated. Primary outcomes of this study were feasibility and safety, evaluated by whether NMES sessions were successfully achieved, and by any adverse events and complications. Secondary outcomes included indices of rhabdomyolysis from biochemical blood tests 24 h after the application of NMES. Results: All patients successfully completed their NMES session, with no adverse events or complications. The majority of patients achieved type 4 and 5 qualities of muscle contraction. Conclusions: NMES is a safe and feasible exercise methodology for patients supported with ECMO.

Methadone in combination with magnesium, ketamine, lidocaine, and dexmedetomidine improves postoperative outcomes after coronary artery bypass grafting: an observational multicentre study

BACKGROUND

An optimal pharmacological strategy for fast-track cardiac anesthesia (FTCA) is unclear. This study evaluated the effectiveness and safety of an FTCA program using methadone and non-opioid adjuvant infusions (magnesium, ketamine, lidocaine, and dexmedetomidine) in patients undergoing coronary artery bypass grafting.

METHODS

This retrospective, multicenter observational study was conducted across private and public teaching sectors. We studied patients managed by a fast-track protocol or via usual care according to clinician preference. The primary outcome was the total mechanical ventilation time in hours adjusted for hospital, body mass index, category of surgical urgency, cardiopulmonary bypass time and EuroSCORE II. Secondary outcomes included successful extubation within four postoperative hours, postoperative pain scores, postoperative opioid requirements, and the development of postoperative complications.

RESULTS

We included 87 patients in the fast-track group and 88 patients in the usual care group. Fast-track patients had a 35% reduction in total ventilation hours compared with usual care patients (p = 0.007). Thirty-five (40.2%) fast-track patients were extubated within four hours compared to 10 (11.4%) usual-care patients (odds ratio: 5.2 [95% CI: 2.39-11.08; p < 0.001]). Over 24 h, fast-track patients had less severe pain (p < 0.001) and required less intravenous morphine equivalent (22.00 mg [15.75:32.50] vs. 38.75 mg [20.50:81.75]; p < 0.001). There were no significant differences observed in postoperative complications or length of hospital stay between the groups.

CONCLUSION

Implementing an FTCA protocol using methadone, dexmedetomidine, magnesium, ketamine, lignocaine, and remifentanil together with protocolized weaning from a mechanical ventilation protocol is associated with significantly reduced time to tracheal extubation, improved postoperative analgesia, and reduced opioid use without any adverse safety events. A prospective randomized trial is warranted to further investigate the combined effects of these medications in reducing complications and length of stay in FTCA.

TRIALS REGISTRATION

The study protocol was registered in the Australian New Zealand Clinical Trials Registry ( https://www.anzctr.org.au/ACTRN12623000060640.aspx , retrospectively registered on 17/01/2023).

A protocolized five strategies in open repair for ruptured abdominal aortic aneurysm

OBJECTIVES

Although the medical field has made significant progress, there has been little improvement in the survival rate of patients with ruptured abdominal aortic aneurysms (rAAAs). We implemented a protocol consisting of five strategies in the management of rAAA patients who underwent open repair surgery.

METHODS

The protocol comprised the following strategies: intentional hypotension <70 mmHg, lung first and kidney last policy (restricted fluid resuscitation and permissive oligoanuria), immediate postoperative extubation, free-water intake with active ambulation, and open abdomen with the routine second-look operation. The study included 13 patients (11 male) with a mean age of 75.5 ± 7.4 (range: 58-87) years who underwent the procedure from 2016 to 2018, with a mean follow-up of 40.1 ± 9.04 months. Five deteriorating to hemodynamic shock and decreased consciousness requiring intubation and ventilation prior to surgery were observed. Two of these patients required preoperative cardiopulmonary resuscitation (CPR).

RESULTS

All patients regained consciousness after surgery, including the two patients who required cardiopulmonary resuscitation. Immediate postoperative extubation was performed in nine patients, but two (22.2%) of them needed re-intubation due to ventilation/perfusion mismatch. Four patients underwent continuous renal replacement therapy, with three of them having anuria for up to 48 h after surgery. Two of these patients made a full recovery. Daily ambulation was carried out for a mean of 4.77 ± 3.5 (range 1-13) days with an open abdomen, during which no significant events were reported. Four cases of colon ischemia/necrosis were identified in the second-look operation, with two patients requiring Hartman's procedure and the other two undergoing left colon partial resection. There were two in-hospital mortalities (15.4%).

CONCLUSIONS

A protocol-based approach, through multidisciplinary team consensus and the development of optimal surgical strategies, could improve clinical outcomes for patients undergoing emergency surgery for rAAA. Further studies with larger sample sizes are needed to refine the protocols.

The Effect of Colloids versus Crystalloids for Goal-Directed Fluid Therapy on Prognosis in Patients Undergoing Noncardiac Surgery: A Meta-Analysis of Randomized Controlled Trials

Background

Goal-directed fluid therapy (GDFT) contributes to improvements in intraoperative fluid infusion based on objective parameters and has been widely recommended in clinical practice. In addition, increasing evidence reveals that GDFT can improve the prognosis of surgical patients. However, considering the individual characteristics of colloids and crystalloids in clinical use, it is uncertain as to which type of fluids administered is associated with better outcomes in the condition of GDFT.

Objectives

To evaluate the effect of colloids versus crystalloids under GDFT on prognosis in patients undergoing noncardiac surgery. Data Sources. Randomized controlled trials (RCTs) from PubMed, EMBASE, Ovid MEDLINE, CNKI, Cochrane library, and reference lists of relevant articles.

Methods

Two investigators independently screened and reviewed studies for inclusion and performed data extraction. Our primary outcome was a composite of postoperative complications. The secondary outcomes were (1) mortality at the follow-up duration; (2) postoperative complications of several organ systems, including cardiac, pulmonary, digestive, urinary, nervous system, and postoperative infection events; and (3) hospital and ICU length of stay. Heterogeneity was assessed by the I 2 and chi-square tests. The odds ratio (OR) of the dichotomous data, mean difference (MD) of continuous data, and 95% confidence intervals (CI) were calculated to assess the pooled data.

Results

Of 332 articles retrieved, 15 RCTs (involving 2,956 patients undergoing noncardiac surgery) were included in the final analysis. When the data were pooled, patients in the colloids and crystalloids group revealed no difference in postoperative composite complications (OR = 0.84, 95% CI = 0.51-1.38, P=0.49) under GDFT. Regarding the secondary outcomes, patients in the colloids group were associated with fewer digestive system complications (OR = 0.64, 95% CI = 0.41-0.98, P=0.04). However, no difference was found in mortality (OR = 1.37, 95% CI = 0.72-2.58, P=0.34), complications of the cardiac system (OR = 1.49, 95% CI = 0.66-3.37, P=0.34), pulmonary system (OR = 0.89, 95% CI = 0.62-1.28, P=0.53), urinary system (OR = 1.05, 95% CI = 0.61-1.80, P=0.87), nervous system (OR = 1.04, 95% CI = 0.55-1.98, P=0.90), postoperative infection events (OR = 0.89, 95% CI = 0.75-1.07, P=0.22), length of hospital stay (difference in mean = -0.71, 95% CI = -1.49-0.07, P=0.07), and ICU stay (difference in mean = -0.01, 95% CI = -0.20-0.18, P=0.95) between patients receiving GDFT with colloids or crystalloids.

Conclusion

There is no evidence of a benefit in using colloids over crystalloids under GDFT in patients undergoing noncardiac surgery, despite its use resulting in lower digestive system complications.

Safety and quality of parenteral nutrition: Areas for improvement and future perspectives

PURPOSE

This article is based on presentations and discussions held at the International Safety and Quality of Parenteral Nutrition (PN) Summit (held November 8-10, 2021, at Charleston, SC, and Bad Homburg, Germany) and aims to raise awareness concerning unresolved issues associated with the PN process and potential future directions, including a greater emphasis on patients' perspectives and the role of patient support.

SUMMARY

Ensuring that every patient in need receives adequate PN support remains challenging. It is important to have a standardized approach to identify nutritional risk and requirements using validated nutritional screening and assessment tools. Gaps between optimal and actual clinical practices need to be identified and closed, and responsibilities in the nutrition support team clarified. Use of modern technology opens up opportunities to decrease workloads or liberate resources, allowing a more personalized care approach. Patient-centered care has gained in importance and is an emerging topic within clinical nutrition, in part because patients often have different priorities and concerns than healthcare professionals. Regular assessment of health-related quality of life, functional outcomes, and/or overall patient well-being should all be performed for PN patients. This will generate patient-centric data, which should be integrated into care plans. Finally, communication and patient education are prerequisites for patients' commitment to health and for fostering adherence to PN regimes.

CONCLUSION

Moving closer to optimal nutritional care requires input from healthcare professionals and patients. Patient-centered care and greater emphasis on patient perspectives and priorities within clinical nutrition are essential to help further improve clinical nutrition.

Association of Arterial Carbon Dioxide Tension Following In-Hospital Cardiac Arrest With Survival and Favorable Neurologic Outcome

BACKGROUND

In-hospital cardiac arrest (IHCA) continues to be associated with high morbidity and mortality. The objective of this study was to study the association of arterial carbon dioxide tension (PaCO2) on survival to discharge and favorable neurologic outcomes in adults with IHCA.

METHODS

The study population included 353 adults who underwent resuscitation from 2011 to 2019 for IHCA at an academic tertiary care medical center with arterial blood gas testing done within 24 hours of arrest. Outcomes of interest included survival to discharge and favorable neurologic outcome, defined as Glasgow outcome score of 4-5.

RESULTS

Of the 353 patients studied, PaCO2 classification included: hypocapnia (PaCO2 <35 mm Hg, n = 89), normocapnia (PaCO2 35-45 mm Hg, n = 151), and hypercapnia (PaCO2 >45 mm Hg, n = 113). Hypercapnic patients were further divided into mild (45 mm Hg < PaCO2 ≤55 mm Hg, n = 62) and moderate/severe hypercapnia (PaCO2 > 55 mm Hg, n = 51). Patients with normocapnia had the highest rates of survival to hospital discharge (52.3% vs. 32.6% vs. 30.1%, P < 0.001) and favorable neurologic outcome (35.8% vs. 25.8% vs. 17.9%, P = 0.005) compared those with hypocapnia and hypercapnia respectively. In multivariable analysis, compared to normocapnia, hypocapnia [odds ratio (OR), 2.06; 95% confidence interval (CI), 1.15-3.70] and hypercapnia (OR, 2.67; 95% CI, 1.53-4.66) were both found to be independently associated with higher rates of in-hospital mortality. Compared to normocapnia, while mild hypercapnia (OR, 2.53; 95% CI, 1.29-4.97) and moderate/severe hypercapnia (OR, 2.86; 95% CI, 1.35-6.06) were both independently associated with higher in-hospital mortality compared to normocapnia, moderate/severe hypercapnia was also independently associated with lower rates of favorable neurologic outcome (OR, 0.28; 95% CI, 0.11-0.73), while mild hypercapnia was not.

CONCLUSIONS

In this prospective registry of adults with IHCA, hypercapnia noted within 24 hours after arrest was independently associated with lower rates of survival to discharge and favorable neurologic outcome.

APASL clinical practice guidelines on the management of acute kidney injury in acute-on-chronic liver failure

Acute-on-chronic liver failure (ACLF) is a syndrome that is characterized by the rapid development of organ failures predisposing these patients to a high risk of short-term early death. The main causes of organ failure in these patients are bacterial infections and systemic inflammation, both of which can be severe. For the majority of these patients, a prompt liver transplant is still the only effective course of treatment. Kidneys are one of the most frequent extrahepatic organs that are affected in patients with ACLF, since acute kidney injury (AKI) is reported in 22.8-34% of patients with ACLF. Approach and management of kidney injury could improve overall outcomes in these patients. Importantly, patients with ACLF more frequently have stage 3 AKI with a low rate of response to the current treatment modalities. The objective of the present position paper is to critically review and analyze the published data on AKI in ACLF, evolve a consensus, and provide recommendations for early diagnosis, pathophysiology, prevention, and management of AKI in patients with ACLF. In the absence of direct evidence, we propose expert opinions for guidance in managing AKI in this very challenging group of patients and focus on areas of future research. This consensus will be of major importance to all hepatologists, liver transplant surgeons, and intensivists across the globe.

What every Intensivist should know about ... Ammonia in liver failure

PURPOSE

Acute liver failure (ALF) or acute-on-chronic liver failure (ACLF) patients have high short-term mortality and morbidity. In the context of liver failure, increased serum ammonia is associated with worse neurological outcomes, including high-grade hepatic encephalopathy (HE), cerebral edema, and intracranial hypertension. Besides its neurotoxicity, hyperammonemia may contribute to immune dysfunction and the risk of infection, a frequent trigger for multi-organ failure in these patients.

MATERIAL AND METHODS

We performed a literature-based narrative review. Publications available in PubMed® up to June 2023 were considered.

RESULTS

In the ICU management of liver failure patients, serum ammonia may play an important role. Accordingly, in this review, we focus on recent insights about ammonia metabolism, serum ammonia measurement strategies, hyperammonemia prognostic value, and ammonia-targeted therapeutic strategies.

CONCLUSIONS

Serum ammonia may have prognostic value in liver failure. Effective ammonia targeted therapeutic strategies are available, such as laxatives, rifaximin, L-ornithine-l-aspartate, and continuous renal replacement therapy.

Physical function and activity of patients after open abdominal surgery: a prospective cohort study comparing the clinimetric properties of two outcome measures

OBJECTIVES

To measure and compare the clinimetric properties of the Chelsea Critical Care Physical Assessment (CPAx) and Physical Function in Intensive Care Test-scored (PFIT-s) for assessment of physical function and activity.

DESIGN

Prospective cohort design using crossover-randomisation of the sequence in which participants were assessed with CPAx and PFIT-s.

SETTING

Surgical and transplant intensive care units (ICU) in an academic hospital.

PARTICIPANTS

Adults who underwent elective open abdominal surgery. Consecutive sampling was used to enrol 69 participants.

INTERVENTIONS

Physical function and activity were assessed on ICU days one, three, five and at ICU discharge using the CPAx and PFIT-s in random order.

MAIN OUTCOME MEASURES

Responsiveness to change, minimal clinically important difference (MCID), floor and ceiling effect, and convergent validity.

RESULTS

CPAx demonstrated a large responsiveness (effect size index (ESI)= 0.83) and PFIT-s moderate responsiveness (ESI=0.73) to change in scores. MCID for CPAx was 2.1 (standard error of measurement (SEM) 1.1) and for PFIT-s 0.6 (SEM=0.3). CPAx had no floor effect and a small ceiling effect (9%, n = 6) at ICU discharge compared to 2% (n = 1) floor and 48% (n = 32) ceiling effects of PFIT-s. Moderate convergent validity was found for both tools at ICU admission (n = 67, r = 0.62, p < 0.001) and discharge (n = 67, r = 0.51, p < 0.001).

CONCLUSION

CPAx is most responsive to changes in physical function and activity scores, has no floor and limited ceiling effects and moderate convergent validity, and is recommended for similar cohorts. CONTRIBUTION OF THE PAPER.

Assessment of postoperative pain in children following sclerotherapy of vascular malformations: a retrospective single centre cohort study

BACKGROUND

Inadequately controlled postprocedural pain following sclerotherapy in patients with vascular malformations is a well recognised problem. Reliable epidemiological data and risk factors associated with postprocedural pain in children are lacking.

OBJECTIVES

To evaluate and quantify postprocedural pain in children and identify possible risk factors based on characteristics of the patient, treatment, and medication.

DESIGN

A retrospective single centre cohort study.

SETTING

A tertiary single centre study in the Netherlands.

PATIENTS

Two hundred and nine chiuldren with 'simple' subtypes of congenital vascular malformation who had undergone sclerotherapy.

PRIMARY OUTCOME MEASURE

Quantifying inadequately controlled postprocedural pain.

SECONDARY OUTCOME MEASURES

Identifying potential patient and treatment characteristics associated with inadequately controlled postprocedural pain.

RESULTS

A total of 209 patients who underwent 679 procedures were included in this study. The mean age at first intervention was 11.8 ± 4.5 years. Inadequately controlled postprocedural pain was found in 34.8% of the 679 procedures. Venous malformations (VM) were the most prevalent subtype of vascular malformation (80%), followed by arteriovenous malformations (AVM) (14.6%) and lymphatic malformations (LM) (5.4%). The odds ratio (OR) (95% confidence intervals), and P values obtained from multivariable mixed effect logistic regression analysis for patient and treatment characteristics found to be associated with inadequately controlled postprocedural pain were: chronic use of analgesics (OR 2.74 (1.40 to 5.34), P = 0.003), treatment with ethanol (OR 2.39 (1.01 to 5.65, P = 0.05) or esketamine (OR 7.43 (1.32 to 41.81), P = 0.02). Patients treated with lauromacrogol (OR 0.42 (0.22 to 0.82, P = 0.01) and patients receiving intra-operative NSAIDs (OR 0.32, (0.12 to 0.85), P = 0.02) were less likely to experience inadequately controlled postprocedural pain.

CONCLUSIONS

Despite aiming to achieve best practice, the 34.8% incidence of unsatisfactory postoperative pain management in the children studied confirms that postprocedural pain after sclerotherapy is a common problem that requires further attention.

Emergent Management of Hypoxic-Ischemic Brain Injury

OBJECTIVE

This article outlines interventions used to improve outcomes for patients with hypoxic-ischemic brain injury after cardiac arrest.

LATEST DEVELOPMENTS

Emergent management of patients after cardiac arrest requires prevention and treatment of primary and secondary brain injury. Primary brain injury is minimized by excellent initial resuscitative efforts. Secondary brain injury prevention requires the detection and correction of many pathophysiologic processes that may develop in the hours to days after the initial arrest. Key physiologic parameters important to secondary brain injury prevention include optimization of mean arterial pressure, cerebral perfusion, oxygenation and ventilation, intracranial pressure, temperature, and cortical hyperexcitability. This article outlines recent data regarding the treatment and prevention of secondary brain injury. Different patients likely benefit from different treatment strategies, so an individualized approach to treatment and prevention of secondary brain injury is advisable. Clinicians must use multimodal sources of data to prognosticate outcomes after cardiac arrest while recognizing that all prognostic tools have shortcomings.

ESSENTIAL POINTS

Neurologists should be involved in the postarrest care of patients with hypoxic-ischemic brain injury to improve their outcomes. Postarrest care requires nuanced and patient-centered approaches to the prevention and treatment of primary and secondary brain injury and neuroprognostication.

Continuous renal replacement therapy and survival in acute liver failure: A systematic review and meta-analysis

OBJECTIVE

Acute liver failure (ALF) is a rare syndrome leading to significant morbidity and mortality. An important cause of mortality is cerebral edema due to hyperammonemia. Different therapies for hyperammonemia have been assessed including continuous renal replacement therapy (CRRT). We conducted a systematic review and meta-analysis to determine the efficacy of CRRT in ALF patients.

MATERIALS AND METHODS

We searched MEDLINE, EMBASE, Cochrane Library, and Web of Science. Inclusion criteria included adult patients admitted to an ICU with ALF. Intervention was the use of CRRT for one or more indications with the comparator being standard care without the use of CRRT. Outcomes of interest were overall survival, transplant-free survival (TFS), mortality and changes in serum ammonia levels.

RESULTS

In total, 305 patients underwent CRRT while 1137 patients did not receive CRRT. CRRT was associated with improved overall survival [risk ratio (RR) 0.83, 95% confidence interval (CI) 0.70-0.99, p-value 0.04, I2 = 50%] and improved TFS (RR 0.65, 95% CI 0.49-0.85, p-value 0.002, I2 = 25%). There was a trend towards higher mortality with no CRRT (RR 1.24, 95% CI 0.84-1.81, p-value 0.28, I2 = 37%). Ammonia clearance data was unable to be pooled and was not analyzable.

CONCLUSION

Use of CRRT in ALF patients is associated with improved overall and transplant-free survival compared to no CRRT.

Bilateral glymphatic dysfunction and its association with disease duration in unilateral temporal lobe epilepsy patients with hippocampal sclerosis

OBJECTIVE

In this study, the diffusion tensor imaging along perivascular space analysis (DTI-ALPS) technique was utilized to evaluate the functional changes in the glymphatic system of the bilateral hemispheres in patients with unilateral temporal lobe epilepsy (TLE) accompanied by hippocampal sclerosis (HS). The aim was to gain insights into the alterations in the glymphatic system function in TLE patients.

METHODS

A total of 61 unilateral TLE patients with HS and 53 healthy controls (HCs) from the Department of Neurosurgery at Xiangya Hospital were included in the study. All subjects underwent DTI using the same 3 T MR Scanner, and the DTI-ALPS index was calculated. Differences in the DTI-ALPS index between TLE patients and HCs were evaluated, along with the correlation between the DTI-ALPS index of TLE and clinical features of epilepsy. These features included age, age of onset, seizure duration, and neuropsychological scores.

RESULTS

Compared to the bilateral means of the HCs, both the ipsilateral and contralateral DTI-ALPS index of the TLE patients were significantly decreased (TLE ipsilateral 1.41 ± 0.172 vs. HC bilateral mean: 1.49 ± 0.116, p = 0.006; TLE contralateral: 1.42 ± 0.158 vs. HC bilateral mean: 1.49 ± 0.116, p = 0.015). The ipsilateral DTI-ALPS index in TLE patients showed a significant negative correlation with disease duration (r = -0.352, p = 0.005).

CONCLUSIONS

The present study suggests the presence of bilateral dysfunctions in the glymphatic system and also highlight a laterality feature in these dysfunctions. Additionally, the study found a significant negative correlation between the ipsilateral DTI-ALPS index and disease duration, underscoring the significance of early effective interventions and indicating potential for the development of innovative treatments targeting the glymphatic system.

Is "Less be More" Still a Valid Concept in Intensive Care? A Review of Critical Care Randomized Clinical Trials from the New England Journal of Medicine

The concept of "Less is more" has been gaining increasing awareness and acceptance in Critical Care. In 2017, we attempted to systematically answer the question "Can less be more in intensive care" with empirical data. We reviewed all the critical care randomized clinical trials (RCTs) between 1 January 2008 and 5 October 2016 in the New England Journal of Medicine (NEJM). This article attempts to repeat the earlier exercise using data from 5 October 2016 to 31 December 2023. This analysis of critical care RCTs in the NEJM has shown three findings. Approximately three-quarter of RCTs in critical care in the NEJM between 2008 and 2023 failed to show benefit or harm. In the years 2008-2016, patients in the intervention cohort had a higher mortality compared to controls, but in the years 2016-2023, the difference in overall mortality in patients in the intervention and control arms was not statistically significant. Compared to the years 2008-2016, in the years from 2016 to 2023, the number of RCTs showing harm decreased and those showing benefit increased.

Cerebral perfusion and metabolism with mild hypercapnia vs. normocapnia in a porcine post cardiac arrest model with and without targeted temperature management

Aim

To determine whether targeting mild hypercapnia (PaCO2 7 kPa) would yield improved cerebral blood flow and metabolism compared to normocapnia (PaCO2 5 kPa) with and without targeted temperature management to 33 °C (TTM33) in a porcine post-cardiac arrest model.

Methods

39 pigs were resuscitated after 10 minutes of cardiac arrest using cardiopulmonary bypass and randomised to TTM33 or no-TTM, and hypercapnia or normocapnia. TTM33 was managed with intravasal cooling. Animals were stabilized for 30 minutes followed by a two-hour intervention period. Hemodynamic parameters were measured continuously, and neuromonitoring included intracranial pressure (ICP), pressure reactivity index, cerebral blood flow, brain-tissue pCO2 and microdialysis. Measurements are reported as proportion of baseline, and areas under the curve during the 120 min intervention period were compared.

Results

Hypercapnia increased cerebral flow in both TTM33 and no-TTM groups, but also increased ICP (199% vs. 183% of baseline, p = 0.018) and reduced cerebral perfusion pressure (70% vs. 84% of baseline, p < 0.001) in no-TTM animals. Cerebral lactate (196% vs. 297% of baseline, p < 0.001), pyruvate (118% vs. 152% of baseline, p < 0.001), glycerol and lactate/pyruvate ratios were lower with hypercapnia in the TTM33 group, but only pyruvate (133% vs. 150% of baseline, p = 0.002) was lower with hypercapnia among no-TTM animals.

Conclusion

In this porcine post-arrest model, hypercapnia led to increased cerebral flow both with and without hypothermia, but also increased ICP and reduced cerebral perfusion pressure in no-TTM animals. The effects of hypercapnia were different with and without TTM.(Institutional protocol number: FOTS, id 14931).

Optimal timing for early mobilization initiatives in intensive care unit patients: A systematic review and network meta-analysis

OBJECTIVES

Analyse the effect of varying start times for early exercise interventions on the prevention of intensive care unit-acquired weakness.

RESEARCH METHODOLOGY

We conducted a comprehensive search on PubMed, Cochrane Library, Web of Science, Embase, China Biology Medicine Disc, China National Knowledge Infrastructure, Wan Fang Database, and reference lists up to May 2023.

SETTING

We systematically searched the literature for all randomized controlled trials on the effect of early mobilization in patients with critical illness.

MAIN OUTCOME MEASURES

The primary outcome assessed was the incidence of intensive care unit-acquired weakness. The secondary outcomes included: the Medical Research Council Score, the Barthel Index, duration of mechanical ventilation, length of intensive care unit stay, total length of hospital stay, mortality and incidence of intensive care unit-related complications.

RESULTS

The results of meta-analysis showed that compared with routine care, less than 24 hours after admission (RR = 0.44, 95 %CI: 0.28-0.68), more than 24 hours (RR = 0.33, 95 %CI: 0.16-0.67), less than 72 hours after admission (RR = 0.33, 95 %CI: 0.20-0.52) may lead to a lower incidence of intensive care unit-acquired weakness. The results of under surface cumulative ranking showed that early mobilization within 72 hours may have the lowest incidence of intensive care unit-acquired weakness (SUCRA = 81.9 %).

CONCLUSIONS

The current empirical evidence from intensive care unit patients suggests that initiating mobilization protocols within 24-72 hours timeframe following admission to the intensive care unit could potentially be the most beneficial strategy to reduce the incidence of intensive care unit-acquired weakness and the related medical complications. Moreover, this strategy seems to significantly improve rehabilitation and treatment outcomes for these patients.

IMPLICATIONS FOR CLINICAL PRACTICE

According to this study, medical and nursing staff in the intensive care unit have the chance to identify the most suitable timing for the implementation of early rehabilitative measures for patients. This can potentially prevent intensive care unit-acquired weakness and enhance various clinical outcomes for patients.

Impact of dynamic parameter of trends in vital signs on the prediction of serious events in hospitalized patients -a retrospective observational study

Aim

Although early detection of patients' deterioration may improve outcomes, most of the detection criteria use on-the-spot values of vital signs. We investigated whether adding trend values over time enhanced the ability to predict adverse events among hospitalized patients.

Methods

Patients who experienced adverse events, such as unexpected cardiac arrest or unplanned ICU admission were enrolled in this retrospective study. The association between the events and the combination of vital signs was evaluated at the time of the worst vital signs 0-8 hours before events (near the event) and at 24-48 hours before events (baseline). Multivariable logistic analysis was performed, and the area under the receiver operating characteristic curve (AUC) was used to assess the prediction power for adverse events among various combinations of vital sign parameters.

Results

Among 24,509 in-patients, 54 patients experienced adverse events(cases) and 3,116 control patients eligible for data analysis were included. At the timepoint near the event, systolic blood pressure (SBP) was lower, heart rate (HR) and respiratory rate (RR) were higher in the case group, and this tendency was also observed at baseline. The AUC for event occurrence with reference to SBP, HR, and RR was lower when evaluated at baseline than at the timepoint near the event (0.85 [95%CI: 0.79-0.92] vs. 0.93 [0.88-0.97]). When the trend in RR was added to the formula constructed of baseline values of SBP, HR, and RR, the AUC increased to 0.92 [0.87-0.97].

Conclusion

Trends in RR may enhance the accuracy of predicting adverse events in hospitalized patients.

Caregiver burden and impact on COVID-19 patient participation and quality of life one year after ICU discharge - A prospective cohort study

OBJECTIVES

to investigate changes in caregiver strain, mental health complaints and QoL in caregivers of COVID-19 ICU survivors in the first year after discharge, and their associations with patients' participation and quality of life.

METHODS

Post-ICU COVID-19 survivors, needing inpatient rehabilitation and their informal caregivers were included. Caregiver self-administered questionnaires included quality of life, self-rated health, caregiver strain, anxiety and depression symptoms, post-traumatic stress and coping style. Patients' participation in society was assessed and quality of life.

RESULTS

67 patients (78% male) and 57 caregivers (23.6% male) were included. Three months post-ICU, caregivers experienced caregiver strain (32%), anxiety (41%), depressive symptoms (16%) and PTSD (24%). One year post-ICU, rates decreased, still being 11%, 26%, 10% and 5%, respectively. Caregiver anxiety symptoms and self-rated health at three months were associated with worse patient levels of participation and quality of life one year after ICU discharge (p < 0.05).

CONCLUSIONS

COVID-19 caregivers experience high levels of mental health complaints one year after a patient's ICU discharge. Furthermore, our results indicate that patient participation levels and quality of life one year after ICU discharge may be negatively associated by caregiver complaints.

PRACTICAL IMPLICATIONS

Counselling and routine assessment of emotional complaints and unmet needs of the informal caregiver should be incorporated and addressed in the rehabilitation treatment of (COVID-19) post-ICU patients.

Transitions in tracheostomy care: from childhood to adulthood

PURPOSE OF REVIEW

The purpose of this review is to explore the evidence around children and young people who require a tracheostomy and transition into adult services, reflecting on the challenges and considerations for clinical practice as these needs increase.

RECENT FINDINGS

There are a lack of data on the incidence and prevalence of children and young people with a tracheostomy transitioning to adult services for ongoing care. There are significant variations in care needs, technology and previous experiences that demand more than a simple handover process. Examples of service models that support the transition of care exist, however these lack specificity for children and young people with a tracheostomy.

SUMMARY

Further exploration of the needs of children and young people requiring airway technology is indicated, particularly considering the short and long-term education, health, and social care needs.

Clinical application of intrapulmonary percussive ventilation: A scoping review

Impaired respiratory function secondary to acute or chronic respiratory disease poses a significant clinical and healthcare burden. Intrapulmonary percussive ventilation (IPV) is used in various clinical settings to treat excessive airway secretions, pulmonary atelectasis, and impaired gas exchange. Despite IPV's wide use, there is a lack of clinical guidance on IPV application which may lead to inconsistency in clinical practice. This scoping review aimed to summarise the clinical application methods and dosage of IPV used by clinicians and researchers to provide guidance. A two-staged systematic search was conducted to retrieve studies that used IPV in inpatient and outpatient settings. MEDLINE, EMBASE, CINAHL, Scopus, and Google scholar were searched from January 1979 till 2022. Studies with patients aged ≥16 years and published in any language were included. Two reviewers independently screened the title and abstract, reviewed full text articles, and extracted data. Search yielded 514 studies. After removing duplicates and irrelevant studies, 25 studies with 905 participants met the inclusion criteria. This is the first scoping review to summarise IPV application methods and dosages from the available studies in intensive care unit (ICU), acute inpatient (non-ICU), and outpatient settings. Some variations in clinical applications and prescribed dosages of IPV were noted. Despite variations, common trends in clinical application and prescription of IPV dosages were observed and summarised to assist clinicians with IPV intervention. Although an evidence-based clinical guideline could not be provided, this review provides detailed information on IPV application and dosages in order to provide clinical guidance and lays a foundation towards developing a clinical practice guideline in the future.

Post-Intensive Care Syndrome in Neurocritical Care Patients

Post-intensive care syndrome (PICS) refers to unintended consequences of critical care that manifest as new or worsening impairments in physical functioning, cognitive ability, or mental health. As intensive care unit (ICU) survival continues to improve, PICS is becoming increasingly recognized as a public health problem. Studies that focus on PICS have typically excluded patients with acute brain injuries and chronic neurodegenerative problems. However, patients who require neurocritical care undoubtedly suffer from impairments that overlap substantially with those encompassed by PICS. A major challenge is to distinguish between impairments related to brain injury and those that occur as a consequence of critical care. The general principles for the prevention and management of PICS and multidomain impairments in patients with moderate and severe neurological injuries are similar including the ICU liberation bundle, multidisciplinary team-based care throughout the continuum of care, and increasing awareness regarding the challenges of critical care survivorship among patients, families, and multidisciplinary team members. An extension of this concept, PICS-Family (PICS-F) refers to the mental health consequences of the intensive care experience for families and loved ones of ICU survivors. A dyadic approach to ICU survivorship with an emphasis on recognizing families and caregivers that may be at risk of developing PICS-F after neurocritical care illness can help improve outcomes for ICU survivors. In this review, we will summarize our current understanding of PICS and PICS-F, emerging literature on PICS in severe acute brain injury, strategies for preventing and treating PICS, and share our recommendations for future directions.

Pressure injuries in mechanically ventilated COVID-19 patients utilising different prone positioning techniques - A prospective observational study

OBJECTIVES

To compare the incidence and distribution of pressure injuries (PIs) with two approaches to prone positioning for mechanically ventilated COVID-19 patients, and to determine the prevalence of these PIs on intensive care unit (ICU) and hospital discharge.

DESIGN

A prospective observational study.

SETTING

Adult patients admitted to a quaternary ICU with COVID-19-associated acute lung injury, between September 2021 and February 2022.

MAIN OUTCOME MEASURES

Incidence and anatomical distribution of PIs during ICU stay for "Face Down" and "Swimmers Position" as well as on ICU and hospital discharge.

RESULTS

We investigated 206 prone episodes in 63 patients. In the Face Down group, 26 of 34 patients (76 %) developed at least one PI, compared to 10 of 22 patients (45 %) in the Swimmers Position group (p = 0.02). Compared to the Swimmers Position group, the Face Down group developed more pressure injuries per patient (median 1 [1, 3] vs 0 [0, 2], p = 0.04) and had more facial PIs (p = 0.002). In a multivariate logistic regression model, patients were more likely to have at least one PI with Face Down position (OR 4.67, 95 % CI 1.28, 17.04, p = 0.02) and greater number of prone episodes (OR 1.75, 95 % CI 1.12, 2.74, p = 0.01). Over 80 % of all PIs were either stage 1 or stage 2. By ICU discharge, 29 % had healed and by hospital discharge, 73 % of all PIs had healed.

CONCLUSION

Swimmers Position had a significantly lower incidence of PIs compared to the Face Down approach. One-quarter of PIs had healed by time of ICU discharge and three-quarters by time of hospital discharge.

IMPLICATIONS FOR CLINICAL PRACTICE

There are differences in incidence of PIs related to prone positioning approaches. This study validates and helps better inform current prone position guidelines recommending the use of Swimmers Position. The low prevalence of PIs at hospital discharge is reassuring.

Re-revision and mortality rate following revision total hip arthroplasty for infection

Aims

This study compares the re-revision rate and mortality following septic and aseptic revision hip arthroplasty (rTHA) in registry data, and compares the outcomes to previously reported data.

Methods

This is an observational cohort study using data from the German Arthroplasty Registry (EPRD). A total of 17,842 rTHAs were included, and the rates and cumulative incidence of hip re-revision and mortality following septic and aseptic rTHA were analyzed with seven-year follow-up. The Kaplan-Meier estimates were used to determine the re-revision rate and cumulative probability of mortality following rTHA.

Results

The re-revision rate within one year after septic rTHA was 30%, and after seven years was 34%. The cumulative mortality within the first year after septic rTHA was 14%, and within seven years was 40%. After multiple previous hip revisions, the re-revision rate rose to over 40% in septic rTHA. The first six months were identified as the most critical period for the re-revision for septic rTHA.

Conclusion

The risk re-revision and reinfection after septic rTHA was almost four times higher, as recorded in the ERPD, when compared to previous meta-analysis. We conclude that it is currently not possible to assume the data from single studies and meta-analysis reflects the outcomes in the 'real world'. Data presented in meta-analyses and from specialist single-centre studies do not reflect the generality of outcomes as recorded in the ERPD. The highest re-revision rates and mortality are seen in the first six months postoperatively. The optimization of perioperative care through the development of a network of high-volume specialist hospitals is likely to lead to improved outcomes for patients undergoing rTHA, especially if associated with infection.

Update on perioperative fluids

Adequate fluid management in the perioperative period in paediatric patients is essential for restoring and maintaining homeostasis and ensuring adequate tissue perfusion. A well-designed infusion regimen is crucial for preventing severe complications such as hyponatraemic encephalopathies. The composition of perioperative fluid solutions is now guided by an understanding of extracellular fluid physiology. Various crystalloid and colloidal products are available for use, but a comprehensive approach requires careful consideration of their drawbacks and limitations. Additionally, the unique characteristics of different patient groups must be taken into account. This review will provide the reader with physiological considerations for perioperative fluids and describe indications for perioperative intravenous fluid therapy in paediatric patients. The current evidence on perioperative fluid therapy is finally summarised in practical recommendations.

Comparison of Continuous Albumin Infusion, Bolus Albumin, and Crystalloid Fluid Administration in Open-Abdomen Surgical-Trauma Patients

Background: The open abdomen (OA), an intentional lack of fascial closure following abdominal cavity opening, is utilized for various indications among surgical-trauma patients. Among intravenous fluid options, administration of albumin as a continuous infusion may improve outcomes in OA. The purpose of this study is to compare the time to abdomen closure among patients with OA according to type of fluid administration. Methods: We conducted a retrospective cohort study of adults with OA from 2012 through 2018 and stratified by intravenous fluid administration into one of three groups: continuous albumin infusion, intermittent bolus albumin, or crystalloid. The primary outcome was median time to abdomen closure. Secondary outcomes included hemodynamic parameters, length of stay (LOS), and mortality. Time to final abdomen closure was analyzed by Cox proportional hazards regression. Results: Eighty-four patients were included with 28 in each cohort. Compared to crystalloids (44.2 [interquartile range, IQR, 36.3-62.9] hours), median time to abdomen closure was significantly longer in bolus albumin (79.0 [IQR, 44.5-130.8] hours; P = .002) and continuous albumin groups (63.6 [IQR, 42.9-139.6] hours; P = .001) in Cox regression analysis. The incidence of hospital mortality was highest in the bolus albumin cohort (continuous albumin: 21.4% vs bolus albumin: 50.0% vs crystalloid: 25.0%; P = .044). All other secondary outcomes were similar between groups. Conclusions: Among patients with OA, administration of intravenous crystalloid was associated with the shortest time to abdomen closure compared to bolus or continuous albumin. Further evaluation of continuous albumin infusion in patients with OA is needed.

Postorotracheal intubation dysphagia in patients with COVID-19: A retrospective study

BACKGROUND

The cause of oropharyngeal dysphagia in patients with coronavirus disease (COVID-19) can be multifactorial and may underly limitations in swallowing rehabilitation.

OBJECTIVE

Analyze the factors related to dysphagia in patients with COVID-19 immediately after orotracheal extubation and the factors that influence swallowing rehabilitation.

DESIGN AND SETTING

A retrospective study.

METHODS

The presence of dysphagia was evaluated using the American Speech-Language Hearing Association National Outcome Measurement System (ASHA NOMS) scale and variables that influenced swallowing rehabilitation in 140 adult patients who required invasive mechanical ventilation for >48 h.

RESULTS

In total, 46.43% of the patients scored 1 or 2 on the ASHA NOMS (severe dysphagia) and 39.29% scored 4 (single consistency delivered orally) or 5 (exclusive oral diet with adaptations). Both the length of mechanical ventilation and the presence of neurological disorders were associated with lower ASHA NOMS scores (odds ratio [OR]: 0.80, 95% confidence interval [CI]: 0.74-0.87 P < 0.05; and OR: 0.13, 95% CI: 0.61-0.29; P < 0.05, respectively). Age and the presence of tracheostomy were negatively associated with speech rehabilitation (OR: 0.92; 95% CI: 0.87--0.96; OR: 0.24; 95% CI: 0.80--0.75), and acute post-COVID-19 kidney injury requiring dialysis and lower scores on the ASHA NOMS were associated with longer time for speech therapy outcomes (β: 1.62, 95% CI, 0.70-3.17, P < 0.001; β: -1.24, 95% CI: -1.55--0.92; P < 0.001).

CONCLUSION

Prolonged orotracheal intubation and post-COVID-19 neurological alterations increase the probability of dysphagia immediately after extubation. Increased age and tracheostomy limited rehabilitation.

Feasibility and safety of in-bed cycling/stepping in critically ill patients: A study protocol for a pilot randomized controlled clinical trial

BACKGROUND

Intensive care unit (ICU)-acquired weakness (ICU-AW) is one of the most common complications of post-ICU syndrome. It is the leading cause of gait disturbance, decreased activities of daily living, and poor health-related quality of life. The early rehabilitation of critically ill patients can reduce the ICU-AW. We designed a protocol to investigate the feasibility and safety of conventional rehabilitation with additional in-bed cycling/stepping in critically ill patients.

METHODS

The study is designed as a single-center, single-blind, pilot, randomized, parallel-group study. After the screening, participants are randomly allocated to two groups, stratified by mechanical ventilation status. The intervention group will be provided with exercises of in-bed cycling/stepping according to the level of consciousness, motor power, and function in addition to conventional rehabilitation. In contrast, the control group will be provided with only conventional rehabilitation. The length of intervention is from ICU admission to discharge, and interventions will be conducted for 20 minutes, a maximum of three sessions per day.

RESULTS

The outcomes are the number and percentage of completed in-bed cycling/stepping sessions, the duration and percentage of in-bed cycling/stepping sessions, and the number of cessations of in-bed cycling/stepping sessions, the interval from ICU admission to the first session of in-bed cycling/stepping, the number and percentage of completed conventional rehabilitation sessions, the duration and percentage of conventional rehabilitation sessions, the number of cessations of conventional rehabilitation sessions, the number of adverse events, level of consciousness, functional mobility, muscle strength, activities of daily living, and quality of life.

DISCUSSION

This study is a pilot clinical trial to investigate the feasibility and safety of conventional rehabilitation with additional in-bed cycling/stepping in critically ill patients. If the expected results are achieved in this study, the methods of ICU rehabilitation will be enriched.

The current status and global trends of clinical trials related to robotic surgery: a bibliometric and visualized study

Conducting clinical trials can evaluate the effectiveness and safety of surgical robots. To promote the advancement of academic robotic programs in surgery, this study captures the development trend and research hotspots of clinical trials related to surgical robots by bibliometric analysis. Bibliometrix package in R software was used to analyze the publication year, authors, countries, institutes, and journals. The visualization maps of keywords were formed using VOSviewer. The keywords with the strongest citation bursts and the institutional collaboration map were created by CiteSpace. Urology dominates with 31.3% of publications and the controlled clinical trials in urology and orthopedic accounted for the highest proportion, reaching 73%. North America, the USA, and Seoul National University lead in productivity. The most productive country, region and institution are North America, USA and Seoul National University, respectively. The trend of collaboration is regional instead of international. Keyword and burst keyword analysis revealed a primary focus in clinical research on robotic surgery: evaluating process improvements, comparing robotic and traditional surgery, and assessing feasibility. Long-term clinical trials assess surgical robots not only intraoperative performance but also postoperative complications and overall surgical outcomes. The development in the field is unbalanced between regions and countries. To promote multi-center clinical trials, governments can streamline review procedures and establish international consensus review standards, while academic institutions can form academic alliances. Also, the study offers recommendations for the development of academic robotic programs and regional collaboration units in robotic surgery, which may provide researchers with a strong reference for future research.

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.
