Impact of early mobilization on glycemic control and ICU-acquired weakness in critically ill patients who are mechanically ventilated

Association between protein intake and functional capacity in critically ill patients: A retrospective cohort study

BACKGROUND

Intensive care unit (ICU) protein benchmarks are based on mortality and morbidity; whether these targets also support functional recovery is unknown. We assessed whether different protein doses influenced patients' functional capacity, measured by the Chelsea Physical Assessment score (CPAx).

METHODS

Single-center retrospective cohort study on ICU survivors with length of stay ≥7 days admitted between October 2014 and September 2020. Eligible patients were divided according to protein intake (g/kg/day): low (<0.8), medium (0.8-1.19), high (1.2-1.5), and very high (>1.5). Protein dose effect on CPAx was assessed at ICU discharge with analysis of covariance adjusting for age, illness severity, hospital length of stay before ICU admission, time to start nutrition support, and mechanical ventilation duration. We also investigated effect modification by energy intake and nutrition status.

RESULTS

Enrolled patients (n = 531) were similar for age, nutrition status, and illness severity across groups. CPAxs were nonlinearly associated with protein doses and similar among low, medium, and very high groups. The CPAx for the high group was statistically different (P = 0.014), indicating that the data of three groups could be pooled. Mean CPAx difference remained statistically significant after adjusting for confounding variables (3.9 ± 1.8, P = 0.029 in the four-group model, and 2.7 ± 0.9, P = 0.003 in the pooled two-group model). Energy intake was equivalent between groups and did not modify CPAx. The high group had superior CPAx in both well-nourished and malnourished patients, indicating nutrition status was not an effect modifier.

CONCLUSION

Protein dose 1.2-1.5 g/kg/day was associated with superior functional capacity at ICU discharge compared with other doses. Neither energy intake nor nutrition status modified functional capacity across groups; therefore, the results appear to be influenced by 1.2-1.5 g/kg/day.

Impact of High-Dose Early Mobilization on Outcomes for Patients with Diabetes: A Secondary Analysis of the TEAM Trial

Rationale: Patients with diabetes represent almost 20% of all ICU admissions and might respond differently to high-dose early active mobilization. Objectives: To assess whether diabetes modified the relationship between the dose of early mobilization on clinical outcomes in the TEAM trial. Methods: All TEAM trial patients were included. The primary outcome was days alive and out of the hospital at Day 180. Secondary outcomes included 180-day mortality and long-term functional outcomes at Day 180. Logistic and median regression models were used to explore the effect of high-dose early mobilization on outcomes by diabetes status. Measurements and Main Results: All 741 patients from the original trial were included. Of these, 159 patients (21.4%) had diabetes. Patients with diabetes had fewer days alive and out of the hospital at Day 180 (124 [0-153] vs. 147 [82-164]; P = 0.013) and higher 180-day mortality (30% vs. 18%; P = 0.044). In patients receiving high-dose early mobilization, the number of days alive and out of the hospital at Day 180 was 73.0 (0.0-144.5) in patients with diabetes and 146.5 (95.8-163.0) in patients without diabetes (P value for interaction = 0.108). However, in patients with diabetes, high-dose early mobilization increased the odds of mortality at 180 days (adjusted odds ratio, 3.47; 95% confidence interval, 1.67-7.61; P value for interaction = 0.001). Conclusions: In this secondary analysis of the TEAM trial, in patients with diabetes, a high-dose early mobilization strategy did not significantly decrease the number of days alive and out of the hospital at Day 180, but it increased 180-day mortality.

Association of early oral intake after extubation and independent activities of daily living at discharge among intensive care unit patients: A single centre retrospective cohort study

PURPOSE

We investigated the association between the time to first post-extubation oral intake, barriers to oral intake, and the rate of activities of daily living (ADL) independence at discharge (Barthel Index score <70).

METHOD

Consecutive patients admitted to the intensive care unit, aged ≥18 years, and mechanically ventilated for ≥48 hr were retrospectively enrolled. The time to first oral intake, barriers to oral intake, daily changes, and clinical outcomes were assessed. Multiple logistic regression analysis adjusted for baseline characteristics was used to determine the association between time to first post-extubation oral intake and ADL independence.

RESULT

Among the 136 patients, 74 were assigned to the ADL independence group and 62 to the dependence group. The time to first post-extubation oral intake was significantly associated with ADL independence (adjusted p = < 0.001) and was a predictor of ADL independence at discharge. Respiratory and dysphagia-related factors (odds ratio [OR] 0.35; 95% confidence interval [CI] 0.15-0.82, p = 0.015 and OR 0.07; CI 0.01-0.68, p = 0.021, respectively) were significantly associated with the ADL independence at discharge.

CONCLUSION

Respiratory and dysphagia-related factors, as barriers to the initiation of oral intake after extubation, were significantly associated with ADL independence at discharge.

Early predictive value of ultrasound measurements of rectus femoris cross-sectional area to diagnose ICU-acquired weakness in patients undergoing invasive mechanical ventilation: a prospective cohort study

BACKGROUND

The diagnosis of ICU-acquired weakness (ICUAW) may be delayed due to the complexity of critically ill patients. This study aimed to investigate the value of ultrasound measurements of rectus femoris cross-sectional area (RFCSA) in predicting ICUAW in patients undergoing invasive mechanical ventilation.

METHODS

This was a prospective cohort study of patients undergoing mechanical ventilation for at least 48 h. RFCSA was measured using ultrasound in patients upon ICU admission and followed until discharge. Using the Medical Research Council score as the gold standard, we evaluated the diagnostic value of ultrasound measurements in predicting ICUAW. Kaplan-Meier curves were constructed to evaluate and compare the length of ICU stay and duration of invasive mechanical ventilation between patients with and without ICUAW.

RESULTS

Among the 76 patients, 34 (44.7%) were diagnosed with ICUAW using the Medical Research Council score as the gold standard. The RFCSA atrophy rate between day 1 and day 3 was significantly higher in the ICUAW group (7.9 ± 2.8% vs. 4.3 ± 2.1%, p < 0.001). By utilizing a cutoff point of 6.9%, we discovered that the RFCSA atrophy rate exhibited excellent diagnostic accuracy in predicting ICUAW, with a sensitivity of 76.5% and specificity of 92.9%. In ICUAW patients diagnosed based on an RFCSA atrophy rate, the proportion of patients with an ICU stay longer than 14 days was 42.9%, which was significantly higher compared to 22.9% in the non-ICUAW group (HR: 1.768; 95% CI 1.128-2.772; p = 0.006). Similarly, the proportion of patients continuing mechanical ventilation at 14 days was 28.6% versus 4.2% between the two groups (HR: 1.988; 95% CI 1.266-3.120; p < 0.001).

CONCLUSION

Ultrasound measurements of RFCSA provide a reliable method for diagnosing ICUAW and indicating prognosis in patients undergoing invasive mechanical ventilation.

Risk factors for ICU-acquired weakness in sepsis patients: A retrospective study of 264 patients

Background

Sepsis is a common critical illness in intensive care unit (ICU) and an important risk factor for intensive care unit-acquired weakness (ICU-AW). The objective of the study is to analyze the risk factors of ICU-AW in septic patients.

Methods

A total of 264 septic patients admitted to the General Hospital of the Western Theater Command from January 2018 to April 2022 were included in this study. The cohort was divided into 2 groups according to the presence or absence of ICU-AW. Clinical characteristics included age, sex, body mass index, length of ICU stay, multiple organ dysfunction syndrome, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), mechanical ventilation time, intubation, tracheotomy, protective constraint, lactic acid, fasting blood glucose, etc. The clinical characteristics of sepsis were evaluated using logistic regression analysis.

Results

A total of 114 septic patients suffered ICU-AW during their ICU stay. Multivariate binary logistic regression analysis showed that APACHE Ⅱ score, mechanical ventilation time, protective constraint, and lactic acid were independent risk factors for ICU-AW in septic patients. The areas under the receiver operating characteristic curve (AUCs) were 0.791, 0.740 and 0.812, all P < 0.05, and the optimal cut-off values were 24 points, 5 days and 2.12 mmol/L, respectively.

Conclusions

A high APACHE Ⅱ score, long mechanical ventilation time, protective constraint and high lactate concentration are independent risk factors for ICU-AW in septic patients. An APACHE Ⅱ score greater than 24 points, mechanical ventilation time longer than 5 days and lactate concentration higher than 2.12 mmol/L are likely to cause ICU-AW.

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

OBJECTIVES

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

DESIGN

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

SETTING

An academic ICU in Tokyo.

PATIENTS

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

INTERVENTIONS

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

MEASUREMENTS AND MAIN RESULTS

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

CONCLUSIONS

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

TRIAL REGISTRATION

The study protocol was registered with the University Hospital Medical Information Network (UMIN) under the registration number UMIN000044965. Registered July 30, 2021.

The Evolution of Enhanced Recovery After Surgery: Assessing the Clinical Benefits of Developments Within Enhanced Recovery After Surgery Protocols in Adult Cervical Deformity Surgery

STUDY DESIGN

Retrospective cohort.

OBJECTIVE

To investigate the impact of evolving Enhanced Recovery After Surgery (ERAS) protocols on outcomes after cervical deformity (CD) surgery.

BACKGROUND

ERAS can help accelerate patient recovery and assist hospitals in maximizing the incentives of bundled payment models while maintaining high-quality patient care. However, there remains a paucity of literature assessing how developments have impacted outcomes after adult CD surgery.

METHODS

Patients with operative CD 18 years or older with pre-baseline and 2 years (2Y) postoperative data, who underwent ERAS protocols, were stratified by increasing implantation of ERAS components: (1) early (multimodal pain program), (2) intermediate (early protocol + paraspinal blocks, early ambulation), and (3) late (early/intermediate protocols + comprehensive prehabilitation). Differences in demographics, clinical outcomes, radiographic alignment targets, perioperative factors, and complication rates were assessed through Bonferroni-adjusted means comparison analysis.

RESULTS

A total of 131 patients were included (59.4 ± 11.7 y, 45% females, 28.8 ± 6.0 kg/m 2 ). Of these patients, 38.9% were considered "early," 36.6% were "intermediate," and 24.4% were "late." Perioperatively, rates of intraoperative complications were lower in the late group ( P = 0.036). Postoperatively, discharge disposition differed significantly between cohorts, with late patients more likely to be discharged to home versus early or intermediate cohorts [χ 2 (2) = 37.973, P < 0.001]. In terms of postoperative disability recovery, intermediate and late patients demonstrated incrementally improved 6 W modified Japanese Orthopedic Association scores ( P = 0.004), and late patients maintained significantly higher mean Euro-QOL 5-Dimension Questionnaire and modified Japanese Orthopedic Association scores by 1 year ( P < 0.001, P = 0.026). By 2Y, cohorts demonstrated incrementally increasing SWAL-QOL scores (all domains P < 0.028) domain scores versus early or intermediate cohorts. By 2Y, incrementally decreasing reoperation was observed in early versus intermediate versus late cohorts ( P = 0.034).

CONCLUSIONS

The present study demonstrates that patients enrolled in an evolving ERAS program demonstrate incremental improvement in preoperative optimization and candidate selection, greater likelihood of discharge to home, decreased postoperative disability and dysphasia burden, and decreased likelihood of intraoperative complications and reoperation rates.

Efficacy of the "Start to move" protocol on functionality, ICU-acquired weakness and delirium: A randomized clinical trial

OBJECTIVE

To evaluate the efficacy of the Start to move protocol compared to conventional treatment in subjects over 15 years of age hospitalized in the ICU on an improvement in functionality, decrease in ICU-acquired weakness (DAUCI), incidence of delirium, days of mechanical ventilation (MV), length of stay in ICU and mortality at 28 days.

DESIGN

randomized controlled clinical trial.

SETTING

Intensive Care Unit.

PARTICIPANTS

Includes adults older than 15 years with invasive mechanical ventilation more than 48h, randomized allocation.

INTERVENTIONS

Start to move protocol and conventional treatment.

MAIN VARIABLES OF INTEREST

Functionality, incidence of ICU-acquired weakness, incidence of delirium, days on mechanical ventilation, ICU stay and mortality-28 days, ClinicalTrials.gov number, NCT05053724.

RESULTS

69 subjects were admitted to the study, 33 to the Start to move group and 36 to conventional treatment, clinically and sociodemographic comparable. In the "Start to move" group, the incidence of IUCD at ICU discharge was 35.7% vs. 80.7% in the "conventional treatment" group (p=0.001). Functionality (FSS-ICU) at ICU discharge corresponds to 26 vs. 17 points in favor of the "Start to move" group (p=0.001). The difference in Barthel at ICU discharge was 20% in favor of the "Start to move" group (p=0.006). There were no significant differences in the incidence of delirium, days of mechanical ventilation, ICU stay and 28-day mortality. The study did not report adverse events or protocol suspension.

CONCLUSIONS

The application of the "Start to move" protocol in ICU showed a reduction in the incidence of IUAD, an increase in functionality and a smaller decrease in Barthel score at discharge.

Deep Machine Learning Might Aid in Combating Intensive Care Unit-Acquired Weakness

Secondary muscle weakness in critically ill patients like intensive care unit (ICU)-associated weakness is frequently noted in patients with prolonged mechanical ventilation and ICU stay. It can be a result of critical illness, myopathy, or neuropathy. Although ICU-acquired weakness (ICU-AW) has been known for a while, there is still no effective treatment for it. Therefore, prevention of ICU-AW becomes the utmost priority, and knowing the risk factors is crucial. Nevertheless, the pathophysiology and the attributing causes are complex for ICU-AW, and proper delineation and formulation of a preventive strategy from such vast, multifaceted data are challenging. Artificial intelligence has recently helped healthcare professionals understand and analyze such intricate data through deep machine learning. Hence, using such a strategy also helps in knowing the risk factors and their weight as contributors, applying them in formulating a preventive path for ICU-AW worth trials.

Intensive care unit-acquired weakness: Recent insights

Intensive care unit-acquired weakness (ICU-AW) is a common complication in critically ill patients and is associated with a variety of adverse outcomes. These include the need for prolonged mechanical ventilation and ICU stay; higher ICU, in-hospital, and 1-year mortality; and increased in-hospital costs. ICU-AW is associated with multiple risk factors including age, underlying disease, severity of illness, organ failure, sepsis, immobilization, receipt of mechanical ventilation, and other factors related to critical care. The pathological mechanism of ICU-AW remains unclear and may be considerably varied. This review aimed to evaluate recent insights into ICU-AW from several aspects including risk factors, pathophysiology, diagnosis, and treatment strategies; this provides new perspectives for future research.

Intensive Care Unit-Acquired Weakness after Liver Transplantation: Analysis of Seven Cases and a Literature Review

Intensive Care Unit (ICU)-Acquired Weakness (ICU-AW) is a generalized muscle weakness that is clinically detected in critical patients and has no plausible etiology other than critical illness. ICU-AW is uncommon in patients undergoing orthotopic liver transplantation (OLT). Our report sheds light on the highest number of ICU-AW cases observed in a single center on OLT patients with early allograft dysfunction. Out of 282 patients who underwent OLT from January 2015 to June 2023, 7 (2.5%) developed generalized muscle weakness in the ICU and underwent neurophysiological investigations. The neurologic examination showed preserved extraocular, flaccid quadriplegia with the absence of deep tendon reflexes in all patients. Neurophysiological studies, including electromyography and nerve conduction studies, showed abnormalities with fibrillation potentials and the rapid recruitment of small polyphasic motor units in the examined muscles, as well as a reduced amplitude of the compound muscle action potential and sensory nerve action potential, with an absence of demyelinating features. Pre-transplant clinical status was critical in all patients. During ICU stay, early allograft dysfunction, acute kidney injury, prolonged mechanical ventilation, sepsis, hyperglycemia, and high blood transfusions were observed in all patients. Two patients were retransplanted. Five patients were alive at 90 days; two patients died. In non-cooperative OLT patients, neurophysiological investigations are essential for the diagnosis of ICU-AW. In this setting, the high number of red blood cell transfusions is a potential risk factor for ICU-AW.

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

BACKGROUND

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

OBJECTIVE

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

DESIGN

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

SETTING

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

PARTICIPANTS

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

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

The primary outcome was adverse discharge disposition.

RESULTS

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

CONCLUSION

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

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSION

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

Clinical treatment for persistent inflammation, immunosuppression and catabolism syndrome in patients with severe acute pancreatitis (Review)

Severe acute pancreatitis (SAP) is a severe disease with a high prevalence and a 3-15% mortality worldwide, and premature activation of zymogen for any reason is the initial factor for the onset of SAP. Gallstone disease and heavy alcohol consumption are the two most common etiologies of SAP. Persistent inflammation, immunosuppression and catabolism syndrome (PICS) is a life-threatening illness, and there are no effective treatments. The relapse state of PICS mainly leads to high mortality due to septic shock or severe trauma, both of which are dangerous and challenging conditions for clinicians. Thus, it is important for medical staff to identify patients at high risk of PICS and to master the prevention and treatment of PICS in patients with SAP. The present review aims to increase the understanding of the pathogenesis of PICS, produce evidence for PICS diagnosis and highlight clinical treatment for PICS in patients with SAP. With this information, clinical workers could implement standardized and integrated measures at an early stage of SAP to stop its progression to PICS.

Facial nerve neurographies in intensive care unit-acquired weakness

BACKGROUND

Patients with an intensive care unit-acquired weakness (ICU-AW) often present clinically with severe paresis of the limb and trunk muscles while facial muscles appear less affected. To investigate whether the facial nerves are partially spared from this condition, we performed both peripheral and cranial nerve conduction studies in critically ill patients.

METHODS

In patients requiring prolonged ICU therapy, the motor and sensory nerve conduction velocities of the peroneal, ulnar and facial nerves and the muscle action potentials of the associated muscles, as well as the orbicularis oculi reflexes were assessed shortly after admission, and on ICU days 7 and 14.

RESULTS

Eighteen patients were included in the final data analysis (average age 54.2 ± 16.8 years, 8 females). The amplitudes of the peroneal nerve compound muscle action potentials (CMAPs) were reduced in all patients at ICU days 7 and 14 (F(1.39; 23.63) = 13.85; p < 0.001). There was no similar decrease in the CMAP amplitudes of the ulnar or facial nerve. Other parameters of nerve function (latencies, sensory and motor nerve conduction velocities, sensory nerve action potentials) remained unchanged. The reproducibility of the orbicularis oculi reflex was reduced during the disease course, while its latencies did not change significantly during the disease course.

CONCLUSIONS

There is a relative preservation of CMAPs in facial and hand as opposed to foot muscles. This is compatible with the clinical observation that the facial muscles in patients with ICU-AW are less severely affected. This may be primarily a function of the nerve length, and consequently more robust trophic factors in shorter nerves. Trial registration This study was prospectively registered in the German Clinical Trial Register on April 20th 2020 (DRKS00021467).

Predictive value of glycemic gap and stress glycemia ratio among critically ill patients with acute kidney injury: a retrospective analysis of the MIMIC-III database

BACKGROUND AND AIMS

Acute hyperglycemia has been identified as a risk factor for acute kidney injury occurrence and mortality in various diseases. The aim of the current study was to investigate the relationship between stress-induced hyperglycemia and adverse outcomes in critically ill patients with AKI.

METHODS

We extracted clinical data from Multiparameter Intelligent Monitoring in Intensive Care III version 1.4. Blood glucose and glycosylated hemoglobin during the first 24 h of ICU admission were used to calculate glycemic gap and stress hyperglycemia ratio (SHR). The outcomes included ICU mortality and need for renal replacement therapy. The association of the glycemic gap and SHR with outcomes were determined via logistic regression model and receiver-operating curves. The subgroup analysis of patients with and without diabetes was performed separately.

RESULTS

Higher glycemic gap and SHR were observed in patients who had increased need of RRT, higher mortality rates and longer ICU stay. Multivariate analysis demonstrated that higher glycemic gap (OR 1.01, 95%CI 1.00-1.02, P = 0.015), as well as SHR (OR 1.32; 95%CI 1.07-1.64, P = 0.009), were independently associated with ICU mortality after adjusting for potential covariates. In subgroup analysis, the association of glycemic gap and SHR were only significant in the non-diabetic population as for the outcome of ICU mortality (OR 2.25, 95%CI 1.64-3.08, P < 0.001 and OR 1.99; 95%CI 1.46-2.72, P < 0.001, respectively).

CONCLUSIONS

The glycemic gap and SHR might serve as a potential prognostic indicator of ICU mortality in critically ill patients with AKI, especially in the non-diabetic population.

Identifying Comorbid Subtypes of Patients With Acute Respiratory Failure

BACKGROUND

Patients with acute respiratory failure have multiple risk factors for disability following their intensive care unit stay. Interventions to facilitate independence at hospital discharge may be more effective if personalized for patient subtypes.

OBJECTIVES

To identify subtypes of patients with acute respiratory failure requiring mechanical ventilation and compare post-intensive care functional disability and intensive care unit mobility level among subtypes.

METHODS

Latent class analysis was conducted in a cohort of adult medical intensive care unit patients with acute respiratory failure receiving mechanical ventilation who survived to hospital discharge. Demographic and clinical medical record data were collected early in the stay. Clinical characteristics and outcomes were compared among subtypes by using Kruskal-Wallis tests and χ2 tests of independence.

RESULTS

In a cohort of 934 patients, the 6-class model provided the optimal fit. Patients in class 4 (obesity and kidney impairment) had worse functional impairment at hospital discharge than patients in classes 1 through 3. Patients in class 3 (alert patients) had the lowest magnitude of functional impairment (P < .001) and achieved the earliest out-of-bed mobility and highest mobility level of all subtypes (P < .001).

CONCLUSIONS

Acute respiratory failure survivor subtypes identified from clinical data available early in the intensive care unit stay differ in post-intensive care functional disability. Future research should target high-risk patients in early rehabilitation trials in the intensive care unit. Additional investigation of contextual factors and mechanisms of disability is critical to improving quality of life in acute respiratory failure survivors.

Risk factors and predictive model for pulmonary complications in patients transferred to ICU after hepatectomy

OBJECTIVE

Postoperative pulmonary complications (PPCs) seriously harm the recovery and prognosis of patients undergoing surgery. However, its related risk factors in critical patients after hepatectomy have been rarely reported. This study aimed at analyzing the factors related to PPCs in critical adult patients after hepatectomy and create a nomogram for prediction of the PPCs.

METHODS

503 patients' data were collected form the Peking University People's Hospital. Multivariate logistic regression analysis was used to identify independent risk factors to derive the nomogram. Nomogram's discriminatory ability was assessed using the area under the receiver operating characteristic curve (AUC), and calibration was assessed using the Hosmer-Lemeshow goodness-of-fit test and calibration curve.

RESULTS

The independent risk factor for PPCs are advanced age (odds ratio [OR] = 1.026; P = 0.008), higher body mass index (OR = 1.139; P < 0.001), lower preoperative serum albumin level (OR = 0.961; P = 0.037), and intensive care unit first day infusion volume (OR = 1.152; P = 0.040). And based on this, we created a nomogram to predict the occurrence of PPCs. Upon assessing the nomogram's predictive ability, the AUC for the model was 0.713( 95% CI: 0.668-0.758, P<0.001). The Hosmer-Lemeshow test (P = 0.590) and calibration curve showed good calibration for the prediction of PPCs.

CONCLUSIONS

The prevalence and mortality of postoperative pulmonary complications in critical adult patients after hepatectomy are high. Advanced age, higher body mass index, lower preoperative serum albumin and intensive care unit first day infusion volume were found to be significantly associated with PPCs. And we created a nomogram model which can be used to predict the occurrence of PPCs.

The Effects of Early Mobilization on Acquired Weakness in Intensive Care Units: A Literature Review

BACKGROUND

Intensive care unit (ICU)-acquired weakness (ICUAW) is defined as a clinical syndrome of neuromuscular weakness, and a consequence of critical illness, unrelated to any other etiology. It is associated with difficult weaning from the ventilator, prolonged ICU stay, increased mortality, and other important long-term outcomes. Early mobilization is defined as any active exercise in which patients use their muscle strength actively or passively within the first 2 to 5 days of critical illness. Early mobilization can be safely initiated from the first day of admission to the ICU during mechanical ventilation.

OBJECTIVES

The purpose of this review is to describe the effects of early mobilization on complications from ICUAW.

METHOD

This was a literature review. Inclusion criteria were as follows: observational studies and randomized controlled trials conducted with adult patients (aged ≥18 years) admitted to the ICU were included. Studies selected were published in the last 11 years (2010-2021).

RESULTS

Ten articles were included. Early mobilization reduces muscle atrophy, ventilation, length of hospital stay, and ventilator-associated pneumonia and improves patients' responses to inflammation and hyperglycemia.

DISCUSSION

Early mobilization appears to have a significant impact on the prevention of ICUAW and appears to be safe and feasible. The results of this review could be useful for improving the provision of efficient and effective tailored care for ICU patients.

Association Between Intensive Care Unit-Acquired Weakness and Early Nutrition and Rehabilitation Intensity in Mechanically Ventilated Patients: A Multicenter Retrospective Observational Study

BACKGROUND

Muscle weakness in the intensive care unit (ICU), referred to as ICU-acquired weakness (ICUAW), is a common complication observed in patients receiving mechanical ventilation. This study aimed to investigate whether rehabilitation intensity and nutrition during ICU admission are associated with the incidence of ICUAW.

MATERIALS AND METHODS

Consecutive patients aged ≥18 years who were admitted to the ICU between April 2019 and March 2020 and who received mechanical ventilation for >48 h were eligible. The included patients were divided into two groups: the ICUAW group and the non-ICUAW group. ICUAW was designated by a Medical Research Council score of less than 48 during discharge from the ICU. Patient characteristics, time to achieve ICU mobility scale (IMS) 1 and IMS 3, calorie and protein deliveries, and blood creatinine and creatine kinase levels were evaluated as study data. In this study, the target dose for the first week after admission to the ICU at each hospital was set at 60-70% of the energy requirement calculated by the Harris-Benedict formula. Univariate and multivariate analyses were used to determine the odds ratios (OR) for each factor and to explain the risk factors for the occurrence of ICUAW at ICU discharge.

RESULTS

During the study period, 206 patients were enrolled; 62 of the 143 included patients (43%) had ICUAW. The results of multivariate regression analysis showed that low time to IMS 3 achievement (OR 1.19, 95% confidence interval (CI) 1.01-1.42, p=0.033), and high mean calorie (OR 0.83, 95% CI 0.75-0.93, p<0.001) and protein deliveries (OR 0.27, 95% CI 0.13-0.56, p<0.001) were independently associated with the occurrence of ICUAW.

CONCLUSIONS

Increase in rehabilitation intensity and mean calorie and protein deliveries were associated with a decrease in the occurrence of ICUAW at ICU discharge. Further research is required to validate our results. Our observations, increasing the intensity of physical rehabilitation and the average calorie and protein delivery levels during ICU stay, appear to be the preferred strategies for achieving non-ICUAW.

Insulin signaling in skeletal muscle during inflammation and/or immobilisation

BACKGROUND

The decline in the downstream signal transduction pathway of anabolic hormone, insulin, could play a key role in the muscle atrophy and insulin resistance observed in patients with intensive care unit acquired weakness (ICUAW). This study investigated the impact of immobilisation via surgical knee and ankle fixation and inflammation via Corynebacterium parvum injection, alone and in combination, as risk factors for altering insulin transduction and, therefore, their role in ICUAW.

RESULTS

Muscle weight was significantly decreased due to immobilisation [estimated effect size (95% CI) - 0.10 g (- 0.12 to - 0.08); p < 0.001] or inflammation [estimated effect size (95% CI) - 0.11 g (- 0.13 to - 0.09); p < 0.001] with an additive effect of both combined (p = 0.024). pAkt was only detectable after insulin stimulation [estimated effect size (95% CI) 85.1-fold (76.2 to 94.0); p < 0.001] irrespective of the group and phosphorylation was not impaired by the different perturbations. Nevertheless, the phosphorylation of GSK3 observed in the control group after insulin stimulation was decreased in the immobilisation [estimated effect size (95% CI) - 40.2 (- 45.6 to - 34.8)] and inflammation [estimated effect size (95% CI) - 55.0 (- 60.4 to - 49.5)] groups. The expression of phosphorylated GS (pGS) was decreased after insulin stimulation in the control group and significantly increased in the immobilisation [estimated effect size (95% CI) 70.6-fold (58.8 to 82.4)] and inflammation [estimated effect size (95% CI) 96.7 (85.0 to 108.5)] groups.

CONCLUSIONS

Both immobilisation and inflammation significantly induce insulin resistance, i.e., impair the insulin signaling pathway downstream of Akt causing insufficient GSK phosphorylation and, therefore, its activation which caused increased glycogen synthase phosphorylation, which could contribute to muscle atrophy of immobilisation and inflammation.

Mitochondrial Dysfunction in Intensive Care Unit-Acquired Weakness and Critical Illness Myopathy: A Narrative Review

Mitochondria are key structures providing most of the energy needed to maintain homeostasis. They are the main source of adenosine triphosphate (ATP), participate in glucose, lipid and amino acid metabolism, store calcium and are integral components in various intracellular signaling cascades. However, due to their crucial role in cellular integrity, mitochondrial damage and dysregulation in the context of critical illness can severely impair organ function, leading to energetic crisis and organ failure. Skeletal muscle tissue is rich in mitochondria and, therefore, particularly vulnerable to mitochondrial dysfunction. Intensive care unit-acquired weakness (ICUAW) and critical illness myopathy (CIM) are phenomena of generalized weakness and atrophying skeletal muscle wasting, including preferential myosin breakdown in critical illness, which has also been linked to mitochondrial failure. Hence, imbalanced mitochondrial dynamics, dysregulation of the respiratory chain complexes, alterations in gene expression, disturbed signal transduction as well as impaired nutrient utilization have been proposed as underlying mechanisms. This narrative review aims to highlight the current known molecular mechanisms immanent in mitochondrial dysfunction of patients suffering from ICUAW and CIM, as well as to discuss possible implications for muscle phenotype, function and therapeutic approaches.

Association between the early mobilization of mechanically ventilated patients and independence in activities of daily living at hospital discharge

Physical dysfunction after discharge from the intensive care unit (ICU) is recognized as a common complication among ICU patients. Early mobilization (EM), defined as the ability to sit on the edge of the bed within 5 days, may help improve physical dysfunction. However, the barriers to, and achievement of, EM and their impact on physical dysfunction have not been fully investigated. This study aimed to investigate the achievement of EM and barriers to it and their impact on patient outcomes in mechanically ventilated ICU patients. We conducted this multicenter retrospective cohort study by collecting data from six ICUs in Japan. Consecutive patients who were admitted to the ICU between April 2019 and March 2020, were aged ≥ 18 years, and received mechanical ventilation for > 48 h were eligible. The primary outcome was the rate of independent activities of daily living (ADL), defined as a score ≥ 70 on the Barthel index at hospital discharge. Daily changes in barriers of mobilization, including consciousness, respiratory, circulatory, medical staff factors, and device factors (catheter, drain, and dialysis), along with the clinical outcomes were investigated. The association among barriers, mobilization, and Barthel index ≥ 70 was analyzed using multivariable logistic regression analysis. During the study period, 206 patients were enrolled. EM was achieved in 116 patients (68%) on the fifth ICU day. The primary outcome revealed that achieving EM was associated with a Barthel index ≥ 70 at hospital discharge [adjusted odds ratio (AOR), 3.44; 95% confidence interval (CI), 1.70-6.96]. Device factors (AOR, 0.31; 95% CI, 0.13-0.75, respectively) were significantly associated with EM achievement. EM was associated with independent ADL at hospital discharge. Time to first mobilization and barriers to achieving mobilization can be important parameters for achieving ADL independence at discharge. Further research is required to determine the most common barriers so that they can be identified and removed.

Short-Term Outcomes of the First-Session Prone Position in Patients With Severe Coronavirus Disease 2019: A Retrospective Chart Review

Introduction Prone positioning during ventilation is recommended for patients with severe coronavirus disease 2019 (COVID-19). However, the efficacy of first-session prone positioning in improving short-term outcomes remains unclear. Therefore, we aimed to investigate the impact of the rate of change in partial pressure of oxygen/fraction of inspired oxygen (P/F) ratio before and after initial prone positioning on activities of daily living (ADL) and outcomes at discharge. Methods In this retrospective chart review, 22 patients with severe COVID-19 who required ventilator management between April and September 2021 were analyzed. Patients with an improvement in the P/F ratio (after initial prone positioning, compared to that before the session) by > 16mHg and < 16mmHg were defined as responders and non-responders, respectively. Results Compared with non-responders, responders had a significantly shorter ventilator duration, a higher Barthel Index at discharge, and a higher proportion of discharged patients. There was a significant between-group difference in chronic respiratory comorbidities, with one case (7.7%) among responders and six cases (66.7%) among non-responders. Conclusions This study is the first of its kind to investigate short-term outcomes in patients with COVID-19 requiring ventilator management after initial prone positioning. After initial prone positioning, responders had higher P/F ratios as well as improved ADLs and outcomes at discharge.

A systematic review and meta-analysis of risk factors for intensive care unit acquired weakness

BACKGROUND

The aim of this meta-analysis is to systematically evaluate and summarize the risk factors of intensive care unit acquired weakness (ICU-AW), to provide evidence-based evidence for the formulation of prevention strategies for ICU-AW.

METHODS

PubMed, EMBASE, Web of Science, CBM (China Biology Medicine, China), Chinese National Knowledge Infrastructure, Chinese WANFANG, and VIP will be searched to define relevant risk factors for ICU-AW. The databases search period is from January 1, 2005 to August 13, 2021. The Newcastle Ottawa Scale (NOS) is used to evaluate the quality of the included studies. RevMan 5.3 analysis software will be used for meta-analysis.

RESULTS

This systematic review and meta-analysis included a total of 12 cohort studies, including 9 international journals and 3 Chinese journals, with a total of 1950 patients, of which 856 had ICU-AW. The results showed that the significant risk factors for ICU-AW included female (odds ratio [OR] = 1.34, 95% confidence interval [CI]: 1.06-1.71; P = .02), mechanical ventilation days (OR = 3.04, 95% CI: 1.82-4.26; P < .00001), age (OR = 6.33, 95% CI: 5.05-7.61; P < .00001), length of intensive care unit (ICU) stay (OR = 3.78, 95% CI: 2.06-5.51; P < .0001), infectious disease (OR = 1.67, 95% CI: 1.20-2.33; P = .002), renal replacement therapy (OR = 1.59, 95% CI: 1.11-2.28; P = .01), use of aminoglucoside drugs (OR = 2.51, 95% CI: 1.54-4.08; P = .0002), sepsis related organ failure assessment (SOFA) score (OR = 1.07, 95% CI: 0.24-1.90; P = .01), hyperglycemia (OR = 2.95, 95% CI: 1.70-5.11; P = .0001).

CONCLUSION

This meta-analysis provides comprehensive evidence-based on the assessment of the risk factors for ICU-AW, their multifactorial etiology was confirmed. This study indicated that female, mechanical ventilation days, age, length of ICU stay, infectious disease, renal replacement therapy, use of aminoglucoside drugs, SOFA score, and hyperglycemia are independent risk factors for ICU-AW. We have not found consistent evidence that corticosteroids, neuromuscular blockers, sepsis have any effect on ICU-AW risk.

Prevention of muscle atrophy in ICU patients without nerve injury by neuromuscular electrical stimulation: a randomized controlled study

Background

Extensive muscle atrophy is a common occurrence in orthopaedics patients who are bedridden or immobilized. The incidence is higher in intensive care unit (ICU) inpatients. There is still controversy about how to use neuromuscular electrical stimulation (NMES) in ICU patients. We aim to compare the effectiveness and safety of NMES to prevent muscle atrophy in intensive care unit (ICU) patients without nerve injury.

Methods

ICU patients without central and peripheral nerve injury were randomized into experimental group I (Exp I: active and passive activity training (APAT) + NMES treatment on the gastrocnemius and tibialis anterior muscle), experimental group II (Exp II: APAT + NMES treatment on gastrocnemius alone), and control group (Ctl: APAT alone). Changes in the strength of gastrocnemius, the ankle range of motion, and the muscle cross-section area of the lower leg were evaluated before and after the intervention. Also, changes in prothrombin time, lactic acid, and C-reactive protein were monitored during the treatment.

Results

The gastrocnemius muscle strength, ankle joint range of motion, and cross-sectional muscle area of the lower leg in the three groups showed a downward trend, indicating that the overall trend of muscle atrophy in ICU patients was irreversible. The decrease in gastrocnemius muscle strength in Exp I and Exp II was smaller than that in the control group (P < 0.05), but there was no difference between Exp I and Exp II. The decrease in active ankle range of motion and cross-sectional area of the lower leg Exp I and Exp II was smaller than that in the control group (P < 0.05), and the decrease in Exp I was smaller than that of Exp II (all P < 0.05). The curative effect in Exp I was better than in Exp II. There were no significant differences in the dynamic changes of prothrombin time, lactic acid, and C-reactive protein during the three groups (P > 0.05).

Conclusion

In addition to early exercise training, NMES should be applied to prevent muscle atrophy for patients without nerve injury in ICU. Also, simultaneous NMES treatment on agonist/antagonist muscle can enhance the effect of preventing muscle atrophy.

Evaluation of severe adverse events during rehabilitation for acute-phase patients: A retrospective cohort study

Early mobilization decreases the likelihood of negative outcomes for acute-phase inpatients. Adverse events occurring during intensive care unit rehabilitation have previously been reported; however, no study has reported the incidence rates for adverse events during the acute rehabilitation phase. This study aimed to investigate the incidence of severe adverse events during acute-phase rehabilitation and evaluate them in detail.Reports of adverse events occurring during acute-phase rehabilitation in a university hospital from April 1, 2011 to March 31, 2018 were retrospectively assessed.Nine severe adverse events occurred during this period (incidence rate, 0.032%), comprising 2 cardiopulmonary arrests, 2 pulseless electrical activity events, 2 deterioration in consciousness events, 1 deterioration in consciousness event due to cerebral infarction, 1 fracture due to a fall, and 1 event involving removal of a ventricular drain. Pulmonary thromboembolism was implicated in 1 adverse event involving pulseless electrical activity and 1 deterioration in consciousness event. The causes for the 6 other adverse events could not be identified. The mean days from admission and the onset of rehabilitation to adverse event occurrence were 22.0 ± 18.2 and 17.9 ± 13.5 days (mean ± standard deviation), respectively. Four of 9 patients died, and 5 patients were discharged home or transferred to other stepdown facilities. When assessed retrospectively, there were no conflicts between patient conditions and the cancellation criteria of rehabilitation by the Japanese Association of Rehabilitation Medicine.The occurrences of severe adverse event may not be related to early mobilization (or onset time of rehabilitation) and compliance status of cancellation criteria.

Association between Early Mobilization in the ICU and Psychiatric Symptoms after Surviving a Critical Illness: A Multi-Center Prospective Cohort Study

This is a prospective multicenter cohort study aiming to investigate the association between early mobilization (EM), defined as a rehabilitation level of sitting at the edge of the bed or higher within 72 h of ICU admission, and psychiatric outcome. Consecutive patients, admitted to the ICU for more than 48 h, were enrolled. The primary outcome was the incidence of psychiatric symptoms at 3 months after hospital discharge defined as the presence of any of three symptoms: depression, anxiety, or post-traumatic stress disorder (PTSD). Risk ratio (RR) and multiple logistic regression analysis were used. As a sensitivity analysis, two methods for inverse probability of treatment weighting statistics were performed. Of the 192 discharged patients, 99 (52%) were assessed. The patients who achieved EM had a lower incidence of psychiatric symptoms compared to those who did not (25% vs. 51%, p-value 0.008, odds ratio (OR) 0.27, adjusted p = 0.032). The RR for psychiatric symptoms in the EM group was 0.49 [95% Confidence Interval, 0.29–0.83]. Sensitivity analysis accounting for the influence of death, loss to follow-up (OR 0.28, adjusted p = 0.008), or potential confounders (OR 0.49, adjusted p = 0.046) consistently showed a lower incidence of psychiatric symptoms in the EM group. EM was consistently associated with fewer psychiatric symptoms.

Impact of protocol-based physiotherapy on insulin sensitivity and peripheral glucose metabolism in critically ill patients

BACKGROUND

The impact of physiotherapy on insulin sensitivity and peripheral glucose metabolism in critically ill patients is not well understood.

METHODS

This pooled analysis investigates the impact of different physiotherapeutic strategies on insulin sensitivity in critically ill patients. We pooled data from two previous trials in adult patients with sequential organ failure assessment score (SOFA)≥ 9 within 72 h of intensive care unit (ICU) admission, who received hyperinsulinaemic euglycaemic (HE) clamps. Patients were divided into three groups: standard physiotherapy (sPT, n = 22), protocol-based physiotherapy (pPT, n = 8), and pPT with added muscle activating measures (pPT+, n = 20). Insulin sensitivity index (ISI) was determined by HE clamp. Muscle metabolites lactate, pyruvate, and glycerol were measured in the M. vastus lateralis via microdialysis during the HE clamp. Histochemical visualization of glucose transporter-4 (GLUT4) translocation was performed in surgically extracted muscle biopsies. All data are reported as median (25th/75th percentile) (trial registry: ISRCTN77569430 and ISRCTN19392591/ethics approval: Charité-EA2/061/06 and Charité-EA2/041/10).

RESULTS

Fifty critically ill patients (admission SOFA 13) showed markedly decreased ISIs on Day 17 (interquartile range) 0.029 (0.022/0.048) (mg/min/kg)/(mU/L) compared with healthy controls 0.103 (0.087/0.111), P < 0.001. ISI correlated with muscle strength measured by medical research council (MRC) score at first awakening (r = 0.383, P = 0.026) and at ICU discharge (r = 0.503, P = 0.002). Different physiotherapeutic strategies showed no effect on the ISI [sPT 0.029 (0.019/0.053) (mg/min/kg)/(mU/L) vs. pPT 0.026 (0.023/0.041) (mg/min/kg)/(mU/L) vs. pPT+ 0.029 (0.023/0.042) (mg/min/kg)/(mU/L); P = 0.919]. Regardless of the physiotherapeutic strategy metabolic flexibility was reduced. Relative change of lactate/pyruvate ratio during HE clamp is as follows: sPT 0.09 (-0.13/0.27) vs. pPT 0.07 (-0.16/0.31) vs. pPT+ -0.06 (-0.19/0.16), P = 0.729, and relative change of glycerol concentration: sPT -0.39 (-0.8/-0.12) vs. pPT -0.21 (-0.33/0.07) vs. pPT+ -0.21 (-0.44/-0.03), P = 0.257. The majority of ICU patients showed abnormal localization of GLUT4 with membranous GLUT4 distribution in 37.5% (3 of 8) of ICU patients receiving sPT, in 42.9% (3 of 7) of ICU patients receiving pPT, and in 53.8% (7 of 13) of ICU patients receiving pPT+ (no statistical testing possible).

CONCLUSIONS

Our data suggest that a higher duration of muscle activating measures had no impact on insulin sensitivity or metabolic flexibility in critically ill patients with sepsis-related multiple organ failure.

Intensive Care Unit-acquired Neuromuscular Weakness: A Prospective Study on Incidence, Clinical Course, and Outcomes

Background

Neuromuscular weakness may manifest subsequent to critical illness in intensive care unit (ICU) patients. This weakness termed as “ICU-acquired weakness” (ICUAW) has a significant bearing on the length of mechanical ventilation, duration of ICU stays, long-term disability, and survival rate. Early identification of ICUAW helps in planning appropriate strategies, as well as in predicting the prognosis and long-term outcomes of these patients.

Aims and objectives

To identify the incidence of new-onset neuromuscular weakness developing among patients admitted in the ICU (ICUAW) and study its clinical course and impact on the duration of ICU stay.

Methods

This prospective observational study evaluated patients admitted to the ICU over a period of 1 year and 3 months (November 1, 2015, to January 31, 2017). All patients fulfilling the inclusion and exclusion criteria were evaluated with the Medical Research Council (MRC) score for muscle strength. Patients with an average score <4 were diagnosed with ICUAW. Included patients were examined on alternate days to study the clinical progression of the weakness till ICU discharge or death of the patient. The duration of ICU stay was noted.

Results and conclusion

The study revealed a significant association of ICUAW with age, Acute Physiology And Chronic Health Evaluation (APACHE II) Score, duration of mechanical ventilation, and ICU mortality. The incidence of the weakness was found to be 7.83% among the patients who survived and 50% among those patients who did not survive critical illness.

Effects of the Intensity and Activity Time of Early Rehabilitation on Activities of Daily Living Dependence in Mechanically Ventilated Patients

OBJECTIVES

The aim of this study was to investigate the association between the Rehabilitation Activity Time score (RATs)-a score based on the level and duration of rehabilitation activities-of ventilated patients in the intensive care unit (ICU) and activities of daily living (ADL) dependence at discharge.

METHODS

This retrospective, single-center study evaluated patients aged >18 years who underwent mechanical ventilation in the ICU for at least 48 h. The patients were categorized into the low- and high-dose rehabilitation groups based on the median RATs. The primary outcome was the rate of ADL dependence at discharge, defined as a Barthel index of <70. The association between low or high doses of rehabilitation and the primary outcome was assessed using multiple logistic regression analysis adjusted by baseline factors.

RESULTS

The rate of ADL dependence at discharge was significantly lower in the high-dose rehabilitation group (low dose 81% vs. high dose 22%, P<0.001). Multivariate analysis showed a significantly lower ADL dependence at discharge among those who received high-dose rehabilitation (P<0.001). Increased RATs during the entire ICU admission period and during ICU admission after meeting the criteria for physiological stability was significantly associated with lower ADL dependence at discharge (P<0.001). Moreover, a higher RATs from low-level activity before meeting the criteria for physiological stability also showed a significant association with lower ADL dependence at discharge (P=0.047).

CONCLUSIONS

ADL dependence was significantly lower among those who underwent high-dose rehabilitation. The RATs was consistently associated with ADL dependence at discharge.

Changes in barriers to implementing early mobilization in the intensive care unit: a single center retrospective cohort study

This study was undertaken to investigate the rate of mobilization, defined as a rehabilitation level of sitting on the edge of a bed or higher, and its association with changes in barriers in the intensive care unit (ICU). Consecutive patients from January 2016 to March 2019 admitted to the ICU, 18 years old or older, who did not meet exclusion criteria, were eligible. The primary outcome was the rate of mobilization. Barriers, their changes on a daily basis, and clinical outcomes, such as walking independence at hospital discharge, were also investigated. The association between the barriers and mobilization, and walking independence were analyzed by multivariate logistic regression analysis. During the study period, 177 patients were enrolled. Mobilization was achieved by 116 patients (66%) by the 7th ICU day. The barrier to mobilization was circulatory status on days 1 and 2, consciousness level on days 3 to 5, and medical staff factors on days 6 and 7. Multivariate analysis showed that consciousness level (OR: 0.38, p=0.01), and medical staff factors (OR: 0.49, p=0.01) were significantly associated with mobilization. By hospital discharge 125 patients (71%) could walk independently. Consciousness level was associated (OR: 0.52, p=0.04) with walking independence. In this study, over half of patients could achieve mobilization within the first 7 days. Barriers to mobilization in the ICU change over time. Consciousness level is significantly associated with both mobilization and independent walking at discharge.

Multidisciplinary, early mobility approach to enhance functional independence in patients admitted to a cardiothoracic intensive care unit: a quality improvement programme

Early mobilisation following cardiac surgery is vital for improved patient outcomes, as it has a positive effect on a patient's physical and psychological recovery following surgery. We observed that patients admitted to the cardiothoracic intensive care unit (CTICU) following cardiac surgery had only bed exercises and were confined to bed until the chest tubes were removed, which may have delayed patients achieving functional independence. Therefore, the CTICU team implemented a quality improvement (QI) project aimed at the early mobilisation of patients after cardiac surgery.A retrospective analysis was undertaken to define the current mobilisation practices in the CTICU. The multidisciplinary team identified various practice gaps and tested several changes that led to the implementation of a successful early mobility programme. The tests were carried out and reported using rapid cycle changes. A model for improvement methodology was used to run the project. The outcomes of the project were analysed using standard 'run chart rules' to detect changes in outcomes over time and Welch's t-test to assess the significance of these outcomes.This project was implemented in 2015. Patient compliance with early activity and mobilisation gradually reached 95% in 2016 and was sustained over the next 3 years. After the programme was implemented, the mean hours required for initiating out-of-bed-mobilisation was reduced from 22.77 hours to 11.74 hours. Similarly, functional independence measures and intensive care unit mobility scores also showed a statistically significant (p<0.005) improvement in patient transfers out of the CTICU.Implementing an early mobility programme for post-cardiac surgery patients is both safe and feasible. This QI project allowed for early activity and mobilisation, a substantial reduction in the number of hours required for initiating out-of-bed mobilisation following cardiac surgery, and facilitated the achievement of early ambulation and functional milestones in our patients.

How to Increase Muscle Mass in Critically Ill Patients: Lessons Learned from Athletes and Bodybuilders

PURPOSE OF REVIEW

Decades of research on nutrition and exercise on athletes and bodybuilders has yielded various strategies to promote anabolism and improve muscle health and growth. We reviewed these interventions in the context of muscle loss in critically ill patients.

RECENT FINDINGS

For critically ill patients, ensuring optimum protein intake is important, potentially using a whey-containing source and supplemented with vitamin D and leucine. Agents like hydroxyl β-methylbutyrate and creatine can be used to promote muscle synthesis. Polyunsaturated fatty acids stimulate muscle production as well as have anti-inflammatory properties that may be useful in critical illness. Adjuncts like oxandralone promote anabolism. Resistance training has shown mixed results in the ICU setting but needs to be explored further with specific outcomes. Critically ill patients suffer from severe proteolysis during hospitalization as well as persistent inflammation, immunosuppression, and catabolism syndrome after discharge. High protein supplementation, ergogenic aids, anti-inflammatories, and anabolic adjuncts have shown potential in alleviating muscle loss and should be used in intensive care units to optimize patient recovery.

Can functional electrical stimulation-assisted cycle ergometry replace insulin infusion in patients? A nested substudy in a randomized controlled trial with 6 months' follow-up

BACKGROUND

Functional electrical stimulation-assisted cycle ergometry (FESCE) can deliver active exercise to critically ill patients, including those who are sedated. Aerobic exercise is known to stimulate skeletal muscle glucose uptake. We asked whether FESCE can reduce intravenous insulin requirements and improve insulin sensitivity in intensive care unit (ICU) patients.

METHOD

We performed an a priori-planned secondary analysis of data from an outcome-based randomized controlled trial (NCT02864745) of FESCE-based early-mobility program vs standard of care in mechanically ventilated patients. We analyzed glucose profile, glucose intake, and insulin requirements during ICU stay in all enrolled patients. In a nested subgroup, we performed hyperinsulinemic (120 mIU/min/m² ) euglycemic clamps at days 0, 7, and 180 (n = 30, 23, and 11, respectively).

RESULTS

We randomized 150 patients 1:1 to receive intervention or standard of care. Seventeen (23%) patients in each study arm had a history of diabetes. During ICU stay, patients received 137 ± 65 and 137 ± 88 g/day carbohydrate (P = .97), and 31 vs 35 (P = .62) of them required insulin infusion to maintain blood glucose 8.61 ± 2.82 vs 8.73 ± 2.67 mM (P = .75, n = 11,254). In those treated with insulin, median daily dose was 53 IU (interquartile range [IQR], 25-95) vs 62 IU (IQR, 26-96) in the intervention and control arm, respectively (P = .44). In the subgroup of patients undergoing hyperglycemic clamps, insulin sensitivities improved similarly and significantly from acute and protracted critical illness to 6 months after discharge.

CONCLUSION

The FESCE-based early-mobility program does not significantly reduce insulin requirements in critically ill patients on mechanical ventilation.

Muscle atrophy in critically ill patients : a review of its cause, evaluation, and prevention

Critically ill patients exhibit prominent muscle atrophy, which occurs rapidly after ICU admission and leads to poor clinical outcomes. The extent of atrophy differs among muscles as follows: upper limb: 0.7%-2.4% per day, lower limb: 1.2%-3.0% per day, and diaphragm 1.1%-10.9% per day. This atrophy is caused by numerous risk factors such as inflammation, immobilization, nutrition, hyperglycemia, medication, and mechanical ventilation. Muscle atrophy should be monitored noninvasively by ultrasound at the bedside. Ultrasound can assess muscle mass in most patients, although physical assessment is limited to almost half of all critically ill patients due to impaired consciousness. Important strategies to prevent muscle atrophy are physical therapy and electrical muscular stimulation. Electrical muscular stimulation is especially effective for patients with limited physical therapy. Regarding diaphragm atrophy, mechanical ventilation should be adjusted to maintain spontaneous breathing and titrate inspiratory pressure. However, the sufficient timing and amount of nutritional intervention remain unclear. Further investigation is necessary to prevent muscle atrophy and improve long-term outcomes. J. Med.

Physical Rehabilitation in Critically Ill Children: A Multicenter Point Prevalence Study in the United States

OBJECTIVES

With decreasing mortality in PICUs, a growing number of survivors experience long-lasting physical impairments. Early physical rehabilitation and mobilization during critical illness are safe and feasible, but little is known about the prevalence in PICUs. We aimed to evaluate the prevalence of rehabilitation for critically ill children and associated barriers.

DESIGN

National 2-day point prevalence study.

SETTING

Eighty-two PICUs in 65 hospitals across the United States.

PATIENTS

All patients admitted to a participating PICU for greater than or equal to 72 hours on each point prevalence day.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

The primary outcome was prevalence of physical therapy- or occupational therapy-provided mobility on the study days. PICUs also prospectively collected timing of initial rehabilitation team consultation, clinical and patient mobility data, potential mobility-associated safety events, and barriers to mobility. The point prevalence of physical therapy- or occupational therapy-provided mobility during 1,769 patient-days was 35% and associated with older age (adjusted odds ratio for 13-17 vs < 3 yr, 2.1; 95% CI, 1.5-3.1) and male gender (adjusted odds ratio for females, 0.76; 95% CI, 0.61-0.95). Patients with higher baseline function (Pediatric Cerebral Performance Category, ≤ 2 vs > 2) less often had rehabilitation consultation within the first 72 hours (27% vs 38%; p < 0.001). Patients were completely immobile on 19% of patient-days. A potential safety event occurred in only 4% of 4,700 mobility sessions, most commonly a transient change in vital signs. Out-of-bed mobility was negatively associated with the presence of an endotracheal tube (adjusted odds ratio, 0.13; 95% CI, 0.1-0.2) and urinary catheter (adjusted odds ratio, 0.28; 95% CI, 0.1-0.6). Positive associations included family presence in children less than 3 years old (adjusted odds ratio, 4.55; 95% CI, 3.1-6.6).

CONCLUSIONS

Younger children, females, and patients with higher baseline function less commonly receive rehabilitation in U.S. PICUs, and early rehabilitation consultation is infrequent. These findings highlight the need for systematic design of rehabilitation interventions for all critically ill children at risk of functional impairments.

Environmental Factors Affecting Early Mobilization and Physical Disability Post-Intensive Care: An Integrative Review Through the Lens of the World Health Organization International Classification of Functioning, Disability, and Health

BACKGROUND

Early mobilization (EM) is one of few potential protective factors associated with reduced physical disability post-intensive care (PD PIC). However, only 45% of intensive care units (ICUs) in the United States routinely practice EM despite its recognized benefits.

OBJECTIVES

To analyze the evidence on the relationship between critical care EM, PD PIC, and environmental factors, using the theoretical lens of the World Health Organization's (WHO's) International Classification of Functioning, Disability, and Health (ICF).

METHOD

The Whittemore and Knafl methodology for integrative reviews and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) reporting guidelines were followed. Qualitative, quantitative, and mixed-methods studies (n = 38) that evaluated EM and 1 or more domains of the WHO ICF were included. Quality was appraised using the Mixed-Methods Appraisal Tool. Study characteristics were evaluated for common themes and relationships. The ICF domains and subdomains pertaining to each study were synthesized.

RESULTS

Early mobilization was related to improved functioning on the disability continuum of the WHO ICF. Early mobilization was influenced by several WHO ICF environmental factors. Dedicated physical and occupational therapy teams in the ICU, interdisciplinary rounds, and positive family and staff perception of EM facilitated intervention delivery. However, poor staffing levels, negative unit culture, perceived workload burden, and lack of equipment, education, and financial support impeded delivery of EM.

DISCUSSION

Early mobilization is a promising intervention that may reduce PD PIC. However, environmental factors negatively influence delivery of EM in the ICU. Several gaps in EM research limit its acceptability in ICU practice. Existing EM research is challenged by poor methodological quality. Further study is necessary to better understand the role of EM on PD PIC and improve patient outcomes following critical illness.

Hyperlactacidemia as a risk factor for intensive care unit-acquired weakness in critically ill adult patients

INTRODUCTION/AIMS

Intensive care unit-acquired weakness (ICUAW) is a severe neuromuscular complication of critical illness. Serum lactate is a useful biomarker in critically ill patients. The relationship between serum lactate level and ICUAW remains controversial. This study evaluated whether hyperlactacidemia (lactate level >2 mmol/L) was an independent risk factor for ICUAW in critically ill adult patients.

METHODS

An observational cohort study was performed in a general multidisciplinary intensive care unit (ICU). Sixty-eight consecutive adult critically ill patients without preexisting neuromuscular disease or a poor pre-ICU functional status whose length of ICU stay was 7 or more days were evaluated. Patients were screened daily for signs of awakening. Muscle strength assessment using the Medical Research Council score was performed on the first day a patient was considered awake. Patients with clinical muscle weakness were considered to have ICUAW.

RESULTS

Among the 68 patients who achieved a satisfactory state of consciousness, the diagnosis of ICUAW was made in 30 patients (44.1%). After multivariate analysis, hyperlactacidemia (P = .02), Acute Physiology and Chronic Health Evaluation II score (P = .04), duration of mechanical ventilation (P = .02), and the use of norepinephrine (P = .04) were found to be significantly associated with the development of ICUAW in critically ill patients.

DISCUSSION

This study shows a number of risk factors to be significantly associated with the development of ICUAW in critically ill adults. These factors should be considered when building early prediction models or designing prevention strategies for ICUAW in future studies.

Long-term outcomes after critical illness: recent insights

Intensive care survivors often experience post-intensive care sequelae, which are frequently gathered together under the term “post-intensive care syndrome” (PICS). The consequences of PICS on quality of life, health-related costs and hospital readmissions are real public health problems. In the present Viewpoint, we summarize current knowledge and gaps in our understanding of PICS and approaches to management.

Critical illness myopathy precedes hyperglycaemia and high glucose variability

BACKGROUND

Critical Illness Myopathy (CIM) is a serious ICU complication, and dysglycaemia is widely regarded as a risk factor. Although glucose variability (GV) has been independently linked to ICU mortality, an association with CIM has not been investigated. This study examines the relationship between CIM and GV.

METHODS

Retrospective investigation including ICU patients with SOFA ≥8, mechanical ventilation, and CIM diagnostics. Glucose readings were collected every 6 h throughout the first week of treatment, when CIM is thought to develop. GV was measured using standard deviation (SD), coefficient of variability (CV), mean absolute glucose (MAG), mean amplitude of glycaemic excursions (MAGE), and mean of daily difference (MODD).

RESULTS

74 patients were included, and 50 (67.6%) developed CIM. Time on glycaemic target (70-179 mg/dL), caloric and insulin intakes, mean, maximum and minimum blood glucose values were similar for all patients until the 5th day, after which CIM patients exhibited higher mean and maximum glucose levels. Significantly higher GV in CIM patients were observed on day 5 (SD, CV, MAG, MAGE), day 6 (MODD), and day 7 (SD, CV, MAG).

CONCLUSIONS

CIM patients developed transient increases in GV and hyperglycaemia only late in the first week, suggesting that myopathy precedes dysglycaemia.

Status of adult inpatient burn rehabilitation in Europe: Are we neglecting metabolic outcomes?

BACKGROUND

Hypermetabolism, muscle wasting and insulin resistance are challenging yet important rehabilitation targets in the management of burns. In the absence of concrete practice guidelines, however, it remains unclear how these metabolic targets are currently managed. This study aimed to describe the current practice of inpatient rehabilitation across Europe.

METHODS

An electronic survey was distributed by the European Burn Association to burn centres throughout Europe, comprising generic and profession-specific questions directed at therapists, medical doctors and dieticians. Questions concerned exercise prescription, metabolic management and treatment priorities, motivation and knowledge of burn-induced metabolic sequelae. Odds ratios were computed to analyse associations between data derived from the responses of treatment priorities and knowledge of burn-induced metabolic sequelae.

RESULTS

Fifty-nine clinicians with 12.3 ± 9 years of professional experience in burns, representing 18 out of 91 burn centres (response rate, 19.8%) across eight European countries responded. Resistance and aerobic exercises were only provided by 42% and 38% of therapists to intubated patients, 87% and 65% once out-of-bed mobility was possible and 97% and 83% once patients were able to leave their hospital room, respectively. The assessment of resting energy expenditure by indirect calorimetry, muscle wasting and insulin resistance was carried out by only 40.7%, 15.3% and 7.4% respondents, respectively, with large variability in employed frequency and methods. Not all clinicians changed their care in cases of hypermetabolism (59.3%), muscle wasting (70.4%) or insulin resistance (44.4%), and large variations in management strategies were reported. Significant interdisciplinary variation was present in treatment goal importance ratings, motivation and knowledge of burn-induced metabolic sequelae. The prevention of metabolic sequelae was regarded as the least important treatment goal, while the restoration of functional status was rated as the most important. Knowledge of burn-induced metabolic sequelae was linked to higher importance ratings of metabolic sequelae as a therapy goal (odds ratio, 4.63; 95% CI, 1.50-14.25; p < 0.01).

CONCLUSION

This survey reveals considerable non-uniformity around multiple aspects of inpatient rehabilitation across European burn care, including, most notably, a potential neglect of metabolic outcomes. The results contribute to the necessary groundwork to formulate practice guidelines for inpatient burn rehabilitation.

Hypoalbuminemia on Admission as an Independent Risk Factor for Acute Functional Decline after Infection

The risk of acute functional decline increases with age, and concepts including frailty and post-acute care syndrome have been proposed; however, the effects of the nutritional status currently remain unclear. Patients admitted to the emergency department of Hitachi General Hospital for infectious diseases between April 2018 and May 2019 were included. To identify risk factors for functional decline at discharge, defined as Barthel Index <60, we investigated basic characteristics, such as age, sex, disease severity, the pre-morbid care status, and cognitive impairment, as well as laboratory data on admission, including albumin as a nutritional assessment indicator. In total, 460 surviving patients out of 610 hospitalized for infection were analyzed. In a multivariable logistic regression analysis, factors independently associated with Barthel Index <60 at discharge were age (adjusted OR 1.03, 95%CI 1.01–1.06, p = 0.022), serum albumin (adjusted OR: 0.63, 95%CI: 0.41–0.99, p = 0.043), and the need for care prior to admission (adjusted OR: 5.92, 95%CI: 3.15–11.15, p < 0.001). Hypoalbuminemia on admission in addition to age and the need for care prior to admission were identified as risk factors for functional decline in patients hospitalized for infection. Functional decline did not correlate with the severity of illness.

Mobilization practices in critically ill children: a European point prevalence study (EU PARK-PICU)

Background

Early mobilization of adults receiving intensive care improves health outcomes, yet little is known about mobilization practices in paediatric intensive care units (PICUs). We aimed to determine the prevalence of and factors associated with physical rehabilitation in PICUs across Europe.

Methods

A 2-day, cross-sectional, multicentre point prevalence study was conducted in May and November 2018. The primary outcome was the prevalence of physical therapy (PT)- or occupational therapy (OT)-provided mobility. Clinical data and data on patient mobility, potential mobility safety events, and mobilization barriers were prospectively collected in patients admitted for ≥72 h.

Results

Data of 456 children admitted to one of 38 participating PICUs from 15 European countries were collected (456 patient days); 70% were under 3 years of age. The point prevalence of PT- and/or OT-provided mobility activities was 39% (179/456) (95% CI 34.7–43.9%) during the patient days, with significant differences between European regions. Nurses were involved in 72% (924/1283) of the mobility events; in the remaining 28%, PT/OT, physicians, family members, or other professionals were involved. Of the factors studied, family presence was most strongly positively associated with out-of-bed mobilization (aOR 7.83, 95% CI 3.09–19.79). Invasive mechanical ventilation with an endotracheal tube was negatively associated with out-of-bed mobility (aOR 0.28, 95% CI 0.12–0.68). Patients were completely immobile on 25% (115/456) of patient days. Barriers to mobilization were reported on 38% of patient days. The most common reported patient-related barriers were cardiovascular instability (n = 47, 10%), oversedation (n = 39, 9%), and medical contraindication (n = 37, 8%). Potential safety events occurred in 6% of all documented mobilization events.

Conclusion

Therapists are infrequently consulted for mobilization of critically ill children in European PICUs. This study highlights the need for a systematic and interdisciplinary mobilization approach for critically ill children.

Graphical abstract

Effect of Nighttime Earplugs and Eye Masks on Sleep Quality in Intensive Care Unit Patients

Purpose

Poor sleep quality in intensive care unit (ICU) can be associated with poor outcome. Excessive noise and lights in ICU are known to disrupt patients’ sleep by causing arousals.

Study design

A prospective randomized controlled study.

Materials and methods

The patients admitted to the medical ICU were prospectively included and randomized to receive earplugs and eye masks or no intervention during their first 5 nights in ICU. Their arousal index and other sleep parameters were measured during the first night by polysomnography. Secondary outcomes including wrist actigraphy profiles and subjective sleep quality were recorded during all study nights.

Results

Seventeen patients were enrolled. Eight patients were randomized to earplugs and eye masks group and nine patients were randomized to control group during their first 5 nights in the ICU. The use of earplugs and eye masks demonstrated the trend toward lower arousal index during the first night (21.15 (14.60) vs 42.10 (18.20) events per hour, p = 0.086) and increased activity index (activity count/hour) (16.12 (7.99) vs 10.84 (10.39) count/hour, p = 0.059) compared to control group. Polysomnography and actigraphy did not demonstrate good agreement.

Conclusion

The use of earplugs and eye masks has a trend toward reduction in arousal index and increased activity in patients admitted to ICU. Limited sample size most likely explained insignificant difference in outcomes. Wrist actigraphy did not accurately measure sleep parameters in ICU patients.

Gross motor developmental dysfunctional outcomes in infantile and toddler pediatric intensive care unit survivors

Background

Increasing studies have focused on motor function/dysfunction in PICU survivors; however, most studies have focused on adults and older children. This study investigated gross motor developmental function outcomes in infantile and toddler pediatric intensive care unit (PICU) survivors and the factors associated with gross motor developmental functions.

Methods

This observational study was conducted in the PICU of the First Hospital of Jilin University between January 2019 and March 2019. Thirty-five eligible patients were divided into the dysfunctional (n = 24) or non-dysfunctional (n = 11) group according to the results of the Peabody Developmental Motor Scales, Second Edition (PDMS-2). Baseline gross motor function for all participants before PICU admission was measured via the Age and Stages Questionnaires, Third Edition (ASQ-3). The PDMS-2 was used to evaluate gross motor development function before PICU discharge.

Results

The gross motor developmental dysfunction incidence was 68.6%. Linear correlation analysis showed that the gross motor quotient (GMQ) was positively correlated with the pediatric critical illness score (PCIS, r = 0.621, P < 0.001), and negatively correlated with length of PICU stay (r = − 0.556, P = 0.001), days sedated (r = − 0.602, P < 0.001), days on invasive mechanical ventilation (IMV; r = − 0.686, P < 0.001), and days on continuous renal replacement therapy (CRRT; r = − 0.538, P = 0.001). Linear regression analysis showed that IMV days (β = − 0.736, P = 0.001), sepsis (β = − 18.111, P = 0.003) and PCIS (β = 0.550, P = 0.021) were independent risk factors for gross motor developmental dysfunction.

Conclusions

Gross motor developmental dysfunction in infantile and toddler PICU survivors is more common and may be exacerbated by experiences associated with longer IMV days and increasing illness severity combined with sepsis.

Life after paediatric intensive care unit

Advances in critical care medicine have led to reduced mortality but increased morbidity. Post-intensive care unit syndrome (PICS) develops after critical illness and presents as cognitive, physical and/or psychosocial impairments. PICS is prevalent in 10 - 36% of patients after discharge from paediatric intensive care unit. Multiple risk factors are associated with PICS, but there is no single causal factor. Factors range from clinical illnesses to intensive care intervention. The care plan should be aimed at prevention, early identification and post-ICU management of PICS by a multidisciplinary team.
