BACKGROUND: Although immunomodulators have established benefit against the new coronavirus disease (COVID-19) in general, it is uncertain whether such agents improve outcomes without increasing the risk of secondary infections in the specific subgroup of previously immunocompromised patients. We assessed the effect of immunomodulators on outcomes of immunocompromised patients hospitalized for COVID-19. METHODS: The protocol was prospectively registered with PROSPERO (CRD42022335397). MEDLINE, Cochrane Central Register of Controlled Trials and references of relevant articles were searched up to 01-06-2022. Authors of potentially eligible randomized controlled trials were contacted to provide data on immunocompromised patients randomized to immunomodulators vs control (i.e., placebo or standard-of-care). FINDINGS: Eleven randomized controlled trials involving 397 immunocompromised patients hospitalized for COVID-19 were included. Ten trials had low risk of bias. There was no difference between immunocompromised patients randomized to immunomodulators vs control regarding mortality [30/182 (16.5%) vs 41/215 (19.1%); RR 0.93, 95% CI 0.61-1.41; p = 0.74], secondary infections (RR 1.00, 95% CI 0.64-1.58; p = 0.99) and change in World Health Organization ordinal scale from baseline to day 15 (weighed mean difference 0.27, 95% CI -0.09-0.63; p = 0.15). In subgroup analyses including only patients with hematologic malignancy, only trials with low risk of bias, only trials administering IL-6 inhibitors, or only trials administering immunosuppressants, there was no difference between comparators regarding mortality. INTERPRETATION: Immunomodulators, compared to control, were not associated with harmful or beneficial outcomes, including mortality, secondary infections, and change in ordinal scale, when administered to immunocompromised patients hospitalized for COVID-19.

Background: Medical devices commonly used for the treatment and care of critically ill patients can cause pressure injuries in intensive care units (ICUs). The endotracheal tube (ETT) is one of the most common medical devices to cause pressure injuries. Aim: This study investigated the incidence of, characteristics of and risk factors for ETT‐related pressure injuries for ICU patients. Study Design: This study adopted a prospective descriptive research design. The sample consisted of 146 endotracheally intubated patients. Data were collected using a patient information form, an Endotracheal Tube‐Related Pressure Injuries Assessment Form, the Braden Risk Assessment Tool and the Nutritional Assessment Test. Results: The study revealed that 80.14% of the patients developed ETT‐related pressure injuries. Over half of the ETT‐related pressure injuries appeared on Day 3 or 4 (56.41%). High body mass index was found to be associated with the development of ETT‐related pressure injuries (OR: 1.15, 95% CI: 1.05–1.26, p =.003). None of the other variables were statistically significant in the development of pressure injuries. Conclusions: The incidence of ETT‐related pressure injuries was quite high in the internal, surgical and anaesthesia ICUs. High body mass index was associated with the development of ETT‐related pressure injuries. Intensive care nurses should implement interventions to prevent ETT‐related pressure injuries in critically ill patients receiving mechanical ventilation support. Relevance to Clinical Practice: ETT‐related pressure injuries are common in ICU patients. High body mass index was associated with the development of ETT‐related pressure injuries in critically ill patients. The skin and mucosa should be assessed for the development of ETT‐related pressure injuries during the daily assessment of the patients receiving mechanical ventilation support. The ETT should be repositioned regularly, and the most suitable ETT fixation method should be used. [ABSTRACT FROM AUTHOR]

Patients in delirium require trustful communication and re‐orientation. We developed a flyer with positive, re‐orientating suggestions for families of delirious patients in intensive care units. Suggestions include creating a safe environment, interpreting unusual behaviours positively and fostering mental resilience. Additionally, families are encouraged to prioritize their own well‐being, recognizing their crucial role in supporting their loved ones. This flyer offers practical strategies across four key areas: ensuring security and orientation, reframing noises and body experiences, managing agitation and reshaping perceptions. By equipping families with knowledge and tools, this resource aims to promote understanding, resilience and strength to humanize delirium care. [ABSTRACT FROM AUTHOR]

Background: High‐flow nasal cannula (HFNC) therapy is a non‐invasive respiratory treatment characterized by high tolerability, which largely derives from the patient's comfort. Aim: The primary aim of this study was to explore whether the patient's perceived comfort was the same regardless of different approaches used to reach the target humidification temperature. The secondary aim was to assess the patient's perceived nasal dryness and humidity. Study Design: This single‐centre, pragmatic, randomized trial was registered at clinicaltrials.gov (NCT05688189). Patients in the intensive care unit (ICU) in need of HFNC therapy were randomly assigned to one of three study arms: a two‐step increase (31 to 34 to 37°C), a one‐step increase in temperature (34–37°C) or no temperature increase (started and remained at 37°C). The patients were asked to rate their perceived comfort, as well as their perceived nasal dryness and humidity on a scale from 1 (lowest value) to 5 (highest value). Results: We enrolled 21 patients, aged 34–85 years. The mean (±1 standard deviation) comfort level was 3.3 (1.3) for patients who received a one‐step increase, 3.1 (1.3) for those who received no increase and 2.7 (1.7) for those who received a two‐step increase (p =.714). There was also no difference in nasal dryness (p =.05) or humidity (p =.612) across the study arms. Greater comfort was fairly correlated with less nasal humidity (ρ = −0.34, 95% confidence interval −0.68 to 0.07) but not with nasal dryness (ρ = 0.01, p =.94). Conclusions: After 30 min of HFNC therapy at a target temperature of 37°C, overall comfort was rated similarly in the three study arms. Additional studies are needed to accumulate evidence corroborating the findings of this study. Relevance to Clinical Practice: The temperature of the mixture of air and oxygen is a fundamental component of HFNC therapy. A pragmatic approach irrespective of the initial temperature setting seems to yield a similar comfort score in hospitalized patients with mild respiratory failure because of extrapulmonary causes.

Background: In recent decades, intra‐aortic balloon pump (IABP) technology has made significant progress (sheathless insertion technique, different balloon diameters, percutaneous technique and fibre optic IABP) in reducing complications and increasing patient support. Nonetheless, IABP‐related complications are still frequent and are associated with a poor prognosis. Aim: The aim of this systematic review was to identify complications associated with IABP treatment in critically ill patients with a compromised cardiac function. Study Design: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines based on searches in CINAHL (EBSCO), Medline and Embase (Ovid) from January 2012 to April 2023. Quantitative studies were included if they reported as their primary outcome(s) complications of IABP in adult patients because of cardiovascular conditions and were published in English, Norwegian, Swedish or Danish. Study selection, methodological quality assessment and data extraction were performed independently by two authors. The results were synthesized narratively. Results: A total of nine studies were included in the review, most of which were retrospective (eight of nine). Bleeding was the most frequently occurring complication, followed by limb ischaemia, stroke, infection, IABP malfunction, haematoma and other vascular complications. In addition, a correlation between IABP duration and vascular complications was found in three out of nine studies. Lastly, the incidence rate of stroke was higher in patients with axillary IABP than in those with femoral IABP. Conclusions: This systematic review revealed that bleeding and limb ischaemia were the two most frequent complications associated with IABP therapy. We identified a correlation between (a) IABP support time and the development of vascular complications and (b) stroke and implantation of IABP catheter in the axillary artery. Further studies are needed to explore these findings directly. Relevance to Clinical Practice: Increasing critical care nurses' knowledge regarding complications related to IABP support could lead to early identification, potentially lowering the incidence rate of complications.

Background: The primary goal of the intensive care unit is to the anxiety of conscious patients is often ignored in the care unit. Aim: The purpose of this study was to assess the efficacy of various non‐pharmacological therapies for anxiety disorders in adult patients in the intensive care unit, in order to enhance humanistic care in the intensive care unit and to promote the patients' physical and mental recovery together. Study Design: We conducted a systematic and comprehensive search of the literature in five databases (including the Cochrane Library, PubMed, EBSCO, Web of Science, and Embase) covering nearly a decade for randomized controlled trials of non‐pharmacological therapies to reduce anxiety in adult intensive care unit patients. Two researchers independently assessed the quality of the literature, collected and condensed the data, and used STATA software to perform a network meta‐analysis. The ranking probabilities for each intervention were calculated using the Surface under the Cumulative Ranking (SUCRA) method. The study protocol was registered with PROSPERO. Results: This study ultimately included 26 randomized controlled trials involving 2791 adult ICU patients. Non‐pharmacological interventions for anxiety in adult ICU patients included music therapy, aromatherapy, ICU diary, virtual reality, massage therapy, monitoring room diary, and health education. when compared to the control group (usual care), aromatherapy + music therapy [MD = −2.65, 95% CI (−4.76, −0.54)] (P = 0.0137) and music therapy [MD = −1.77, 95% CI (−3.40, −0.13)] (P = 0.0338) were superior in reducing anxiety in adult ICU patients. The results of the network meta‐analysis showed that aromatherapy combined with music therapy significantly alleviated anxiety in adult ICU patients (SUCRA: 99.8%). Conclusions: Music therapy combined with aromatherapy has demonstrated superior effectiveness compared to other non‐pharmacological interventions for reducing anxiety in awake adults in the ICU. However, the underlying mechanisms of this combined therapy require further exploration. Relevance to Clinical Practice: Future research on the use of music therapy combined with aromatherapy in the care unit may help reduce anxiety in patients while fostering their physical and mental healing; however, individual variances and unique clinical circumstances must be considered.

Background: Mechanical ventilation is a core intervention in critical care, but may also lead to negative consequences. Therefore, ventilator weaning is crucial for patient recovery. Numerous weaning interventions have been investigated, but an overview of interventions to evaluate different foci on weaning research is still missing. Aim: To provide an overview of interventions associated with ventilator weaning. Study Design: We conducted a scoping review. A systematic search of the Medline, CINAHL and Cochrane Library databases was carried out in May 2023. Interventions from studies or reviews that aimed to extubate or decannulate mechanically ventilated patients in intensive care units were included. Studies concerning children, outpatients or non‐invasive ventilation were excluded. Screening and data extraction were conducted independently by three reviewers. Identified interventions were thematically analysed and clustered. Results: Of the 7175 records identified, 193 studies were included. A total of six clusters were formed: entitled enteral nutrition (three studies), tracheostomy (17 studies), physical treatment (13 studies), ventilation modes and settings (47 studies), intervention bundles (42 studies), and pharmacological interventions including analgesic agents (8 studies), sedative agents (53 studies) and other agents (15 studies). Conclusions: Ventilator weaning is widely researched with a special focus on ventilation modes and pharmacological agents. Some aspects remain poorly researched or unaddressed (e.g. nutrition, delirium treatment, sleep promotion). Relevance to Clinical Practice: This review compiles studies on ventilator weaning interventions in thematic clusters, highlighting the need for multidisciplinary care and consideration of various interventions. Future research should combine different interventions and investigate their interconnection. [ABSTRACT FROM AUTHOR]

Background: Intensive care unit (ICU) patients are at an increased risk of ocular surface injuries because of various factors such as reduced tear production and impaired protective mechanisms. Despite the significance of ocular care in ICU settings, there is a lack of consensus on effective interventions, leading to inadequate prevention of ocular surface disease (OSD). Aim: This systematic review aimed to assess the effectiveness of nursing eye care in preventing OSD in ICU patients. Secondary objectives included identifying primary risk factors for ocular injuries and examining the most effective preventive methods. Study Design: A systematic review following PRISMA guidelines was conducted, encompassing a literature search, article selection, quality assessment and data synthesis. Studies meeting inclusion criteria were observational studies and clinical trials, focusing on adults admitted to ICUs under sedation and receiving mechanical ventilation. Results: Of 3545 initially identified articles, 12 studies met inclusion criteria. These studies involved a total of 1853 participants. Various interventions were assessed, including saline rinsing, lubricating drops, gel lubricants, occlusion with polyethylene dressing, passive blinking and eyelid closure with tape. Moist chamber occlusion every 6 h combined with gel lubrication emerged as the most effective method in preventing OSD. Conclusions: Gel lubrication along with moist chamber occlusion proved to be the most effective strategy in preventing ocular injuries in ICU patients. Conversely, the routine use of physiological saline was associated with increased severity of corneal lesions. Properly defined protocols and well‐trained nursing teams are crucial for reducing ocular injuries in ICU settings. Relevance to Clinical Practice: The findings underscore the importance of implementing evidence‐based eye care protocols in ICUs, emphasizing the use of gel lubrication and ocular surface protection to mitigate the risk of OSD. This highlights the need for comprehensive training programmes for ICU nursing staff to ensure optimal ocular care delivery. [ABSTRACT FROM AUTHOR]

Background: The quality of the sleep in the intensive care unit (ICU) is generally poor. It is known that several factors contribute to this situation. Aim: To describe the experiences of adult patients during night‐time sleep in the ICU. Design: A qualitative study using a phenomenological approach was conducted from May to October 2021. Patients were intensive care patients (n = 10) who were treated for at least 24 h in tertiary ICUs. Methods: The data were obtained through semi‐structured interviews based on an interview guide. A qualitative content analysis using an inductive approach was performed. Results: The analysis resulted in three main themes: (a) inadequate sleep at night; (b) factors negatively affecting night‐time sleep; and (c) patient expectations for improved night‐time sleep. Night‐time sleep of patients treated in intensive care were determined to generally have inadequate and be interrupted. Patients associated the cause of this situation with the physical environment conditions in the ICU, loud noises made by health employees and emotional reactions. It was stated that some physical environment changes that can be made in ICUs and psychological support will positively affect sleep. Conclusions: Intensive care patients may not have quality night‐time sleep because of multifactorial reasons. Noise in the ICU is a significant factor preventing patients from sleeping. In addition to reorganization of the physical environment to ensure adequate sleep, there is a need for an integrated approach dealing with patients' feelings and concerns. Relevance to Clinical Practice: Each patient has their own unique sleep pattern. To ensure effective management of sleep problems, health professionals should organize care and physical conditions in line with guidelines and create patient‐specific night‐time sleep management programmes.

Background: During the COVID‐19 pandemic, intensive care units (ICUs) were under heavy pressure, with a significantly increased number of severely ill patients. Hospitals introduced restrictions, and families could not visit their ill and dying family members. Patients were cared for without privacy, and several died in shared patient rooms, leaving the intensive care nurse to protect the patient's need for loving care in a vulnerable situation at the end of life. Aim: This study aimed to investigate how piloting and watch over were revealed in end‐of‐life care for patients with COVID‐19 in intensive care COVID‐19. Study Design: A qualitative study was conducted with an abductive approach was conducted. Data were collected via semi‐structured interviews to cover the research area while allowing the informant to talk freely about the topic; 11 informants were interviewed. Results: The findings are presented based on four categories: The road to the decision, End‐of‐life care, Farewell of close family members and Closure. Each category and subcategory reveal how piloting and watch over were addressed in the end‐of‐life care of patients with COVID‐19 in the ICU during the pandemic. Overall findings indicated that workload and organization of care directly affect the quality of care given, the acceptance of privacy and the possibility of dignified end‐of‐life care. Conclusions: Workload directly affects the quality of care, risking dehumanization of the patient. Visiting restrictions hindered supporting family members through the various piloting phases. Visiting restrictions also forced the ICU nurses to take on the role of the relative in watching over the patient. Relevance to Clinical Practice: Collaboration with family members is essential for the intensive care nurse to be able to provide a person‐centred and dignified end‐of‐life care.

Background: The care processes of cardiac surgery patients are difficult, complex and stressful. Nurses, who have an important role in the care of these patients, may experience burnout or poor quality of work life may be affected because of difficult care processes, and professional difficulties. Aim: This study analysed burnout and quality of work life in cardiac surgery nurses. Study Design: This cross‐sectional study was conducted with 68 nurses in the clinic and intensive care unit of a university hospital's cardiovascular surgery department. Clinical nurses care for inpatients in this department, while intensive care nurses care for patients in the intensive care unit. The 'Sociodemographic and Descriptive Characteristics of Nurses Form', 'Maslach Burnout Inventory' and 'Nursing Work Quality of Life Scale' were used to collect the data. Results: The mean score of emotional exhaustion sub‐dimension of Maslach Burnout Inventory was 15.25 ± 5.08 (min: 7, max: 27), the mean score of the personal accomplishment sub‐dimension was 17.48 ± 4.90 (min: 8, max: 27), and the mean score of depersonalization sub‐dimension was 5.60 ± 2.70 (min: 0, max: 13). The mean scores of the emotional exhaustion sub‐dimension (t: −2.380, p:.020, risk ratio [RR]: 1.67, confidence interval [CI]: [14.21, 18.82]) and the personal accomplishment sub‐dimension (t: −2.604, p:.011, RR: 1.00, CI: [16.08, 19.92]) were higher in intensive care nurses. The mean total score of the nursing quality of work life scale was 107.20 ± 14.60 (min: 72, max: 149). A negative statistically significant relationship was found between the mean scores of emotional exhaustion (r: −0.243, p:.045) and depersonalization sub‐dimension (r: −0.325, p:.007) of the Maslach Burnout Scale and the mean total score of the nursing quality of work life scale. Conclusion: In this study, it can be said that cardiac surgery nurses had moderate levels of emotional burnout, personal accomplishment and quality of work life, and low levels of depersonalization. At the same time, it can be seen that intensive care nurses have higher levels of emotional burnout. The increased emotional burnout and depersonalization in nurses decreased the quality of work life. Relevance to Clinical Practice: This study provided an understanding of burnout and quality of work life of cardiac surgery nurses. Strategies can be developed to reduce burnout and improve the quality of the work life of cardiac surgery nurses. Particular attention should be paid to intensive care nurses who experience more burnout on several sub‐dimensions. This may be a good approach to improving the quality of patient care.

Background: Decision aids (DAs) have been proposed to support patients and families with disease information processing and decision‐making, but their effectiveness for critically ill patients and their families is incompletely understood. Aim: To systematically synthesize evidence on the effectiveness of the DAs on the prognosis of critically ill patients and knowledge, anxiety, depression and decisional conflict of their family members. Study Design: Systematic review and meta‐analysis. We conducted a systematic search of literature using PubMed, Embase, Cochrane Library, Web of Science, Cumulative Index to Nursing and Allied Health Literature database, Scopus, PsycNet, CNKI and Wanfang Database from the inception of the databases until May 2023 to identify randomized clinical trials (RCTs) describing DAs interventions targeted at adult intensive care unit (ICU) patients or their families. We also searched grey literature in four databases: Chinese Clinical Trials Registry, Chinese Cochrane Center, Open Grey and GreyNet International. Results: Seven RCTs were included in the review. Meta‐analysis identified longer hospital length of stay (LOS) among all patients compared with usual care (mean difference [MD] = 5.64 days, 95% confidence interval, CI [0.29, 10.98], p =.04), but not in surviving patients (MD = 2.09 days, 95% CI [−3.70, 7.89], p =.48). However, there was no evidence of an effect of DAs on hospital mortality (RR = 1.25, 95% CI [0.92, 1.70], p =.15), ICU LOS (MD = 3.77 days, 95% CI [−0.17, 7.70], p =.06) and length of mechanical ventilation (MD = 0.88 days, 95% CI [−2.22, 3.97], p =.58). DAs led to a statistically significant improvement in family members' knowledge (standard mean difference = 0.84, 95% CI [0.12, 1.56], p =.02). We found no significant effect of DAs on anxiety, depression, post‐traumatic stress disorder, decisional conflict and quality of communication of family members. Conclusions: This review provides effective evidence that DAs can potentially improve the knowledge level of family members while prolonging the hospital LOS among critically ill patients. Relevance to Clinical Practice: Well‐designed large‐scale studies with DAs tailored to the individuals' preferences and existing cultural values are warranted. [ABSTRACT FROM AUTHOR]

Background: Clinical practice guidelines for the prevention of catheter associated urinary tract infection (CAUTI) recommend urinary catheter securement in critical patients although there is scant research on its effectiveness. Aim: To analyse whether securement of an indwelling urinary catheter (IUC) reduces the risk of CAUTI and meatal pressure injury among intensive care unit (ICU) patients and assess medical adhesive‐related skin injury (MARSI) associated with the securement device. Study Design: Open randomized controlled trial involving patients admitted to two ICUs in Spain. In the intervention group (n = 169 patients), the IUC was secured to the thigh using an in‐house device piloted as part of this trial. Controls (n = 181) received standard care, including non‐securement of the IUC. Barrier film spray was applied to the securement site with the aim of preventing MARSI. The definitions of the main outcomes were: CAUTI was diagnosed according to the criteria of the European Centre for Disease Prevention and Control, meatal pressure injury was categorized into four grades and MARSI was classified as either erythema or skin tears. Bivariate analysis and multivariate logistic regression were performed. Log‐rank and Cox regressions were used to compare risk over time to CAUTI and meatal pressure injury in the two groups. Results: Data from 350 patients were analysed, 169 (48.29%) from IG and 181 (51.71%) from CG. In the multiple logistic regression analysis, IUC securement was an independent protective factor against both CAUTI (RR = 0.2, 95% CI [0.05, 0.67]) and meatal pressure injury (RR = 0.31, 95% CI [0.15, 0.58]). The incidence of MARSI was 7.1%. Conclusion: Effective IUC securement significantly reduces the risk of CAUTI and meatal pressure injury among ICU patients. The in‐house device piloted in the present trial is simple for nurses to use, and the incidence of MARSI was low. These results underline the benefits of IUC securement. Relevance to Clinical Practice: Indwelling urinary catheter (IUC) securement reduces the risk of urinary tract infection. IUC securement helps prevent meatal pressure injury. IUC securement with in‐house devices is safe and effective. [ABSTRACT FROM AUTHOR]

Background: Post‐extubation dysphagia (PED) is a common post‐extubation complication that may lead to serious problems, such as malnutrition and longer hospital and intensive care unit (ICU) stays. Aim: To explore factors associated with the readiness for oral intake in post‐extubated critically ill adult patients. Study Design: This prospective observational study involved 125 extubated patients. Readiness for oral intake was assessed using the Gugging Swallowing Screen (GUSS), and regression analysis was used to determine its predictors. Results: The median age of the participants was 40.0 years, and 51.2% were female. The median GUSS score was 12.0 (possible range, 0–20), and 35.2% of the studied patients had severe dysphagia (scored 0–9). Bivariate regression analysis showed that older age, male, higher APACHE II score, body mass index (BMI) ≥30, smoking history, longer ICU stay, muscle relaxants use, large‐bore endotracheal and orogastric tubes and frequent intubation attempts were associated with lower GUSS score (p‐value <.05). Multivariate regression analysis showed that age, BMI and smoking history predicted 37.2% of the variability in the GUSS score (F = 23.865, p‐value <.001). Adding the ICU length of stay, muscle relaxants use, size of the endotracheal tube, size of the orogastric tube and frequency of intubation attempts to the regression model raised the predictability to 86.0% (F = 88.809, p‐value <.001). Conclusions: More than one‐third of extubated patients have severe PED with a high risk of aspiration. Several modifiable factors, such as muscle relaxant use and endotracheal and orogastric tube size, predict post‐extubation readiness for oral intake. Relevance to Clinical Practice: Using endotracheal and orogastric tubes of appropriate sizes, careful assessment of patients with a high risk for difficult intubation, and minimal use of muscle relaxants may help increase patients' readiness for post‐extubation oral intake.

Background: The surge in critically ill COVID‐19 patients caused a shortage of intensive care unit (ICU) beds. Some hospitals temporarily transformed general wards into ICUs to meet this pressing health care demand. Aim: This study aims to evaluate and analyse the risk factors in temporary ICU from the perspective of nurses. By identifying these factors, the goal is to provide actionable insights and recommendations for effectively establishing and managing temporary ICUs in similar crisis scenarios in the future. Study Design: The study was conducted in China within a public hospital. Specifically, it focused on examining 62 nurses working in a temporary ICU that was converted from an infectious disease ward. The research utilized the Hazard Vulnerability Analysis (HVA) scoring method to identify potential threats, evaluate their probability, estimate their impact on specific organizations or regions and calculate the relative risk associated with such occurrences. Results: Staff demonstrated the highest risk percentage (32.74%), with Stuff (16.11%), Space (15.19%) and System (11.30%) following suit. The most critical risk factors included insufficient knowledge and decision‐making competence in critical care (56.14%), lacking decision‐making abilities and skills in renal replacement therapy care (55.37%), inadequate decision‐making capacity and relevant skills in respiratory support care (50.64%), limited decision‐making capability in circulatory support care (45.73%) and unfamiliarity with work procedures or systems (42.09%). Conclusions: Urgent implementation of tailored training and support for temporary ICU nurses is paramount. Addressing capability and skill‐related issues among these nurses supersedes resource availability, infrastructure, equipment and system considerations. Essential interventions must target challenges encompassing nurses' inability to perform critical treatment techniques autonomously and ensure standardized care. These measures are designed to heighten patient safety and elevate care quality during emergencies. These findings offer a viable avenue to mitigate potential moral distress, anxiety and depression among nurses, particularly those transitioning from non‐critical care backgrounds. These nurses swiftly assimilate into temporary ICUs, and the study's insights offer practical guidance to alleviate their specific challenges. Relevance to Clinical Practice: The study on risk factors for converting traditional wards into temporary ICU during the COVID‐19 pandemic, especially from the perspective of nurses, provides crucial insights into the challenges and requirements for effectively establishing and managing these emergency settings. The findings highlight several key areas of concern and opportunities for improvement directly related to clinical practice, particularly in situations where there is a rapid need to adapt to increased demands for critical care. By addressing the identified risk factors through enhanced training, support systems, resource management, process improvements and cultivating a culture of adaptability, not only can the quality of care in temporary ICUs be improved, but also can the health care system be better prepared for future emergencies. These actions will help mitigate the risks associated with such conversions, ultimately benefiting patient safety, staff well‐being and the overall effectiveness of health care services in crises.

Background: Although there are many reasons for extubation failure, maintaining negative or lower positive fluid balances 24 hours before extubation may be a key measure for successful extubation. Aim: To assess the predictive value of fluid balance before extubation and its outcome in mechanically ventilated cases in the intensive care unit (ICU). Study Design: This retrospective cohort study involved collecting clinical data from patients undergoing mechanical ventilation in Lanzhou general adult ICU from January 2022 to December 2022. Based on extubation outcomes, the patients were divided into a successful extubation group and a failed extubation group. Their fluid balance levels 24 h before extubation were compared with analyse the predictive value of fluid balance on extubation outcomes in patients undergoing mechanical ventilation. Results: In this study, clinical data from 545 patients admitted to a general adult ICU were collected. According to the inclusion and exclusion criteria, 265 (48.6%) patients were included, of which 197 (74.3%) were successfully extubated; extubation was unsuccessful in 68 (25.7%) patients. The total intake and fluid balance levels in patients in the failed extubation group 24 h before extubation were significantly higher than those in the successful extubation group, with a median of 2679.00 (2410.44–3193.50) mL versus 2435.40 (1805.04–2957.00) mL, 831.50 (26.25–1407.94) mL versus 346.00 (−163.00–941.50) mL. Receiver operating characteristic (ROC) curve analysis showed that the optimal cut‐off value for predicting extubation outcomes was 497.5 mL (sensitivity 64.7%, specificity 59.4%) for fluid balance 24 h before extubation. The area under the ROC curve was 0.627 (95% confidence interval [CI] 0.547–0.707). Based on the logistic regression model, cumulative fluid balance >497.5 mL 24 h before extubation could predict its outcomes in mechanically ventilated patients in the ICU (OR = 5.591, 95% CI [2.402–13.015], p <.05). Conclusions: The fluid balance level 24 h before extubation was correlated with the outcome of extubation in mechanically ventilated patients in the ICU. The risk of extubation failure was higher when the fluid balance level was >497.5 mL. Relevance to Clinical Practice: Tracheal intubation is a crucial life support technique for many critically ill patients, and determining the appropriate time for extubation remains a challenge for clinicians. Although there are many reasons for extubation failure, acute pulmonary oedema caused by continuous positive fluid balance and volume overload is one of the main reasons for extubation failure. Therefore, it is very important to study the relationship between fluid balance and extubation outcome to improve the prognosis of patients with invasive mechanical ventilation in ICU.

Background: Ventilator‐associated pneumonia (VAP) is one of the common complications in patients in the intensive care unit. Abdominal massage may prevent the development of VAP by reducing residual gastric volume in enterally fed patients. Aim: The purpose of this study is to review the literature on randomized controlled and quasi‐experimental studies evaluating the effectiveness of abdominal massage in preventing VAP. Methods: The PRISMA‐P (Preferred Reporting Items for Systematic Review and Meta‐Analysis Protocols) criteria were taken as the basis for creating the protocol of the systematic review and writing the article. The systematic review was performed using the Google Scholar, PubMed, Web of Science, Scopus, CINAHL and Cochrane Library databases from December 2023 to January 2024. Studies were selected by determining inclusion and exclusion criteria according to the PICOS method. The studies were evaluated using the Joanna Briggs Institute (JBI) tool for quality assessment. Results: Three randomized controlled and one quasi‐experimental study with a total of 225 participants met the inclusion criteria. The four studies conducted on patients in the intensive care unit showed that abdominal massage reduced VAP. The studies reported no adverse effects of abdominal massage. Conclusion: Promising evidence was found for the effect of abdominal massage in preventing VAP. However, scientific studies with larger samples, of higher quality, and using randomized controls and blinding methods are needed to evaluate the unknown dimensions of abdominal massage and determine its beneficial effects on patients. Relevance to Clinical Practice: Several non‐pharmacological methods may decrease VAP incidence and mortality. Abdominal massage may decrease VAP incidence and mortality. [ABSTRACT FROM AUTHOR]

Background: Delirium, which is prevalent in critical care settings, remains underexplored in acute coronary syndrome (ACS) patients in the cardiac intensive care unit (CICU). Aim: To investigate the prevalence and clinical significance of delirium in patients with ACS admitted to the CICU. Study Design: A prospective study (n = 106, mean age 74.2 ± 5.7 years) assessed delirium using the confusion assessment method‐intensive care unit (CAM‐ICU) tool in 21.7% of ACS patients during their CICU stay. Baseline characteristics, geriatric conditions and clinical procedures were compared between delirious and nondelirious patients. The outcomes included in‐hospital mortality, 30‐day and 6‐month mortality, acute adverse events and length of CICU stay and hospital stay (LOS). Results: Delirious patients who were older and had a higher incidence of coronary artery disease underwent more complex procedures (e.g., pacemaker placement). Multivariate analysis identified central venous catheter insertion, urinary catheterization and benzodiazepine use as independent predictors of delirium. Delirium was correlated with prolonged LOS (p <.001) and increased in‐hospital, 30‐day and 6‐month mortality (p <.001). Conclusions: Delirium in ACS patients in the CICU extends hospitalization and increases in‐hospital, 30‐day and 6‐month mortality. Early recognition and targeted interventions are crucial for mitigating adverse outcomes in this high‐risk population. Relevance to Clinical Practice: This study highlights the critical impact of delirium on outcomes in hospitalized patients with ACS in the CICU. Delirium, often overlooked in ACS management, significantly extends hospitalization and increases mortality rates. Nurses and physicians must be vigilant in identifying delirium early, particularly in older ACS patients or those with comorbidities. Recognizing independent predictors such as catheterization and benzodiazepine use allows for targeted interventions to reduce delirium incidence. Integrating routine delirium assessments and preventive strategies into ACS management protocols can improve outcomes, optimize resource utilization and enhance overall patient care in the CICU setting.

Background: Multiple risk assessment scales are available for predicting the development of pressure injuries (PIs) in patients in the intensive care unit (ICU). Most PI risk assessment tools have been validated at the time of admission; however, another time point during treatment could better reflect clinical changes and therefore, the risk of PIs. Aim: The study aimed to examine the predictive validity of PI risk assessment scale designed for ICU patients, the conscious level, mobility, haemodynamic, oxygenation and nutrition (COMHON) index, at several time points or intervals during ICU stay. Study Design: This was an observational prospective study undertaken over a period of 1 year (July 2021–June 2022). Patients admitted to ICU for >3 days were included. The number, location and degree of the PIs were recorded. The level of risk for developing PIs during the stay was determined by calculating the COMHON scores at admission, and 72 h, as well as the highest and mean score. Predictive validity was studied using accuracy parameters and areas under the receiver operating characteristic curve (AUC). The best cutoff point was also determined and used to compare risk between categories. Results: Of the 286 patients included in the study, 160 (59%) were male. The level of severity evaluated using the APACHE II scale was 18.4 ± 5.8 points. Invasive mechanical ventilation was used in 32.1% (n = 92) of the patients and 20.6% (n = 59) received high flow oxygen therapy. The incidence of PI was 15.4% (n = 44), with sacral location in 47.7% (n = 21) and grade II in 75% (n = 33) of the patients. The AUC was 0.907 (0.872–0.942); 0.881 (0.842–0.920); 0.877 (0.835–0.920) and 0.749 (0.667–0.831) at the mean, the highest, 72 h and ICU admission scores, respectively. The best cutoff point was 13 in all patients. The risk of developing a PI was 6.4 times higher in the high‐risk group (>13 points). Conclusions: The best predictive capacity for the COMHON index risk assessment was the mean and highest scores. The predictive accuracy was higher on the third day of the patient's stay than on admission, and this was attributed to the clinical changes observed in some patients over the course of their critical illness. Relevance for Clinical Practice: Patients in ICU are at high risk of developing PIs, therefore, preventive measures should be maximized. Risk assessment should be carried out sequentially owing to the changes that patients present throughout their ICU stay and preventive measures should be used according to the risk level.

Background: Post‐extubation dysphagia deserves attention because it places patients at risk following extubation, especially critically ill patients in intensive care unit. However, there are limited studies of post‐extubation dysphagia in the early stages after extubation. Aim: To investigate the incidence and factors associated with post‐extubation dysphagia among patients in intensive care unit within 24 h of extubation. Study Design: A prospective descriptive study was carried out with 173 adult patients in intensive care unit with tracheal extubation at a tertiary hospital in Guangzhou, China. The Gugging Swallowing Screen was used to evaluate the swallowing function of patients 1, 4 and 24 h after extubation. Demographic and clinical data were retrieved from medical records. Results: The incidence of post‐extubation dysphagia in patients within 1, 4 and 24 h after extubation was 86.71% (n = 150), 63.01% (n = 109) and 43.35% (n = 75), respectively. The risk factors included older age (OR = 1.057, 95%CI [1.039, 1.072], p <.001), cardiovascular disease (OR = 0.098, 95%CI [0.082, 0.127], p =.012), thyroid dysfunction (OR = 5.042, 95%CI [1.527, 13.684], p <.001), non‐post‐operative admission (OR = 3.186, 95%CI [1.142, 14.422], p =.036), mechanical ventilation duration >48 h (OR = 3.558, 95%CI [1.217, 10.385], p =.020), intubation duration >24 h (OR = 0.533, 95%CI [0.278, 0.898], p =.048) and intubation model size ≤7 (OR = 0.327, 95%CI [0.158, 0.788], p <.01). Conclusions: This study revealed a high incidence of post‐extubation dysphagia in critical patients in the 24 h after extubation, with the incidence decreasing over time. Screening of early post‐extubation dysphagia after extubation is needed, but the specific evaluation time point requires further investigation. Patients with older age, cerebrovascular disease, thyroid dysfunction, post‐operative admission, longer mechanical ventilation time, thicker intubation models and longer intubation time have a higher risk of the occurrence of post‐extubation dysphagia. Relevance to Clinical Practice: The incidence of post‐extubation dysphagia is very high in the early stage. Within 24 h after extubation, the patient's swallowing function should be actively evaluated, and the occurrence of aspiration should be vigilant. Patients with older age, cerebrovascular disease, thyroid dysfunction, post‐operative admission, longer mechanical ventilation time, thicker intubation models and longer intubation time should receive more attention.

Background: Incontinence‐associated dermatitis (IAD) is a common problem among critically ill patients with faecal incontinence (FI). However, there are few studies comparing the effects of different faecal collection devices impact the prevention of moderate to severe IAD in this patient population. Aim: This review aims to compare the effectiveness of various devices for collecting faecal matter in preventing moderate to severe IAD in critically ill patients suffering from FI through a network meta‐analysis. Study Design: We conducted a systematic search of PubMed, Embase, ProQuest, CENTRAL, CINAHL Plus with Full Text, China National Knowledge Infrastructure (CNKI), Wan fang, Wei Pu, and China Biomedicine (CBM) from their inception until May 4, 2023. The selected studies were randomized controlled trials (RCTs). Two researchers independently performed study selection and data extraction. We assessed the risk of bias using the Cochrane risk of bias tool Version 2.0. RevMan 5.4 was utilized for conventional pairwise meta‐analysis of direct comparisons, while Stata16.0 was employed for network meta‐analysis. Results: A total of 14 studies, involving 1345 patients, were included in the analysis. Pairwise meta‐analysis showed that an anal bag[odds ratio(OR): 0.07(0.03, 0.20)], a balloon catheter[(OR:0.30(0.15, 0.62)], and an anal bag connected to negative pressure and flushing [(OR: 0.09(0.01,0.68)] all reduced the incidence of moderate to severe IAD in critically ill patients compared with usual care measures, respectively. The cumulative rank probabilities indicated that moderate to severe IAD prevention was more effective when employing balloon catheters connected to negative pressure [surface under the cumulative ranking curve(SUCRA): 20.8%] and anal bags connected to negative pressure (SUCRA: 27.0%) among critically ill patients with FI. Conclusion: FI is a common problem among severely ill patients, and the reduction of moderate and severe IAD incidence is deemed essential. In this review, it is suggested that both balloon catheters connected to negative pressure and anal bags connected to negative pressure are associated with a higher effectiveness in preventing moderate and severe IAD. Relevance to Clinical Practice: The findings of this review can assist healthcare professionals in the selection of suitable stool management devices for the prevention of moderate to severe IAD in critically ill patients with FI.

Background: Deep sedation may be indicated in the intensive care unit (ICU) for the management of acute organ failure, but leads to sedative‐induced delirium. Whether processed electroencephalography (p‐EEG) is useful in this setting is unclear. Aim: To describe the PSI index in deeply sedated critically ill patients with acute organ failure, and to examine a potential association between low PSI values and ICU delirium. [Correction added on 16 October 2024, after first online publication: Aim subsection in Abstract has been added on this version.] Methods: We conducted a single‐centre observational study of non‐neurological ICU patients sedated according to a standardized guideline of deep sedation (Richmond Agitation Sedation Scale [RASS] between −5 and −4) during the acute phase of respiratory and/or cardio‐circulatory failure. The SedLine (Masimo Incorporated, Irvine, California) was used to monitor the Patient State Index (PSI) (ranging from 0 to 100, <25 = very deep sedation and >50 = light sedation to full awareness) during the first 72 h of care. Delirium was assessed with the Confusion Assessment Method for the Intensive Care Unit (CAM‐ICU). Results: The median duration of PSI monitoring was 43 h. Patients spent 49% in median of the total PSI monitoring duration with a PSI <25. Patients with delirium (n = 41/97, 42%) spent a higher percentage of total monitored time with PSI <25 (median 67% [19–91] vs. 47% [12.2–78.9]) in non‐delirious patients (p.047). After adjusting for the cumulative dose of analgesia and sedation, increased time spent with PSI <25 was associated with higher delirium (odds ratio 1.014; 95% CI 1.001–1.027, p =.036). Conclusions: A clinical protocol of deep sedation targeted to RASS at the acute ICU phase may be associated with prolonged EEG suppression and increased delirium. Whether PSI‐targeted sedation may help reducing sedative dose and delirium deserves further clinical investigation. Relevance to Clinical Practice: Patients requiring deep sedation are at high risk of being over‐sedated and developing delirium despite the application of an evidence‐based sedation guideline. Development of early objective measures are essential to improve sedation management in these critically ill patients. [ABSTRACT FROM AUTHOR]

The invasive intra‐arterial approach is the gold standard for measuring blood pressure in intensive care units where accuracy is crucial. However, invasive procedures increase the risk of infections and mortality. This evidence‐based review aimed to determine whether continuous non‐invasive blood pressure (CNIBP) monitoring, using Radial Artery Applanation Tonometry (RAAT) devices, is as accurate as invasive methods. Six papers were included: three prospective cohort studies and three comparative studies. Most studies showed that mean arterial pressure is accurately recorded through RAAT monitoring; however, more research is needed to assess the accuracy of non‐invasive readings of systolic and diastolic blood pressures, as data are not always concordant.

Background: There is scarcity of data on the incidence and factors associated with the occurrence of ocular lesions in critically ill children. Aim: Test the applicability and utility of an ocular assessment scale and to identify risk factors of ocular lesions. Study Design: Prospective observational study. A tertiary care medical‐surgical Paediatric Intensive Care Unit. 194 children without previous ocular disease who stayed in the Paediatric Intensive Care Unit for more than 48 h. An ocular lesions risk scale was designed including risk factors lagophthalmos, eye dryness, conjunctival hyperemia, slow blinking, intubation, sedation, relaxation, face mask and hemodynamic instability. Patients were classified as high‐, medium‐, and low‐risk patients. Corneal lesions were examined by fluorescein staining according to their risk and were confirmed by an ophthalmologist. Results: 76 patients were examined with fluorescein staining. Thirty‐two ocular lesions were detected by nursing staff, 26 confirmed by the ophthalmologist. 53.6% of the high‐risk patients developed a corneal lesion. Univariate analysis revealed an association between ocular damage and all factors included in the scale, except for face mask. In the multivariate analysis, ocular lesions were associated with lagophthalmos, hyperemia, invasive mechanical ventilation and inotropic support. Conclusions: The scale was useful to detect corneal lesions in critically ill children. The identification of risk factors will enable the development of measures to reduce the incidence of ocular lesions. Relevance for Clinical Practice: A new, non‐validated scale allowed staff to detect eye injuries, study this problem and improve future prevention. [ABSTRACT FROM AUTHOR]

Background: Delirium is the most common psychiatric diagnosis in the intensive care unit (ICU), and 55%‐80% of delirium cases are unrecognized and undocumented the most popular validated instruments available to diagnose delirium for critically ill patients are the Confusion Assessment Method for the ICU (CAM‐ICU). [Correction added on 16 October 2024, after first online publication: The Background section in Abstract has been added in this version.] Aim: To identify the validity and predictability of the confusion assessment method for the intensive care unit (CAM‐ICU) for delirium in critically ill patients in the ICU. Study Design: In this systematic review, PubMed, Embase, Cochrane Central Register of Controlled Trials, and MEDLINE databases were searched for observational studies investigating delirium screening tools for ICU patients. In the meta‐analysis, we combined the sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio, and area under the curve (AUC) of SROC to analysis the predictive value of CAM‐ICU. Results: Twenty‐nine articles met the inclusion criteria. The pooled sensitivity and specificity values were 0.82 (95% confidence interval [CI]: 0.75–0.87) and 0.95 (95% CI: 0.93–0.97), respectively. The AUC point estimate of the SROC curve was 0.96 (95% CI: 0.94–0.97). Race (Asian or Others) could affect the pooled sensitivity and specificity, and the analysis method (Patient‐ or Scan‐based) and study design were not sources of heterogeneity for pooled sensitivity and specificity. Conclusions: The CAM‐ICU is a valid and reliable tool for delirium prediction among ICU patients. When introducing CAM‐ICU to assess delirium, it is necessary to localize its language and content to improve its predictive efficacy in different countries and different ethnic groups. Relevance to Clinical Practice: In clinical practice, nurses can use CAM‐ICU to evaluate delirium in critically ill patients in ICU. However, it is necessary to debug the language and content according to the application population. [ABSTRACT FROM AUTHOR]

The intensive care unit (ICU) is the most important department for critically ill patients. Different scoring systems are used to assess the severity of the disease and evaluate organ failure during the patient's stay in ICU. Our purpose was to evaluate the C‐reactive protein/Albumin (CRP/Alb) ratio and SOFA score as indicators of 28‐day mortality in ICU patients. A total of 55 patients were enrolled in this study. CRP and CRP/Alb rates, SOFA scores, and demographic data were used to evaluate 28‐day mortality in a referral hospital. Survived and dead patients were significantly different in the CRP, CRP/Alb rates, and SOFA scores. However, in the adjusted model, the SOFA score was the predictor of 28‐day mortality in ICU patients. SOFA score was also confirmed as a predictor of mortality in ICU patients. Besides, the role of CRP and CRP/Alb in the prediction of disease prognosis or mortality requires further studies. [ABSTRACT FROM AUTHOR]

Background: Diaries have been used regularly in international settings as an evidence‐based and easily applicable intervention following a person‐centred approach in the intensive care unit (ICU). In addition, a diary web application known as 'Post‐ICU' has been implemented. Aim: To explore the usability of an innovative digital diary from the perspectives of intensive care patients' relatives. Study Design: A cross‐sectional online survey study was applied among a convenience sample of relatives in the ICUs of two hospitals in the Netherlands. The investigator‐developed questionnaire included, among other things, items with the appreciation of the layout, user friendliness and functionality of the diary. Relevance and applicability were rated between 1 and 10. Data were analysed with SPSS© software, version 27, and reported as the means (±standard deviation [SD]) and percentages. Results: Sixty‐three relatives with an average age of 51 years (SD ± 14.3) participated in the study; there was a slight predominance of women (57%). All but one participant found using the digital diary easy and were able to upload photos to the diary. The participants had invited other relatives (75%) and nurses (61%) to write in the diary, which they viewed as easily feasible (89%). The relevance and applicability of the diary were rated with mean scores of 8.1 (SD ± 1.9) and 8.3 (SD ± 1.6), respectively. Conclusions: The participants found the Post‐ICU diary web application highly valuable and easily feasible. Perceived ease of use, perceived usefulness and technophobia were not found to influence the usability of the digital diary. Relevance to Clinical Practice: The implementation of this new digital tool supports a person‐centred ICU policy because of its focus on the personal diary entries of the patient and the collaborative writing process featuring relatives and professionals.

OBJECTIVES: Given the uncertainty regarding the optimal approach to laryngoscopy for the intubation of critically ill adult patients, we conducted a systematic review and meta-analysis to compare video laryngoscopy (VL) vs. direct laryngoscopy (DL) for intubation in emergency department and ICU patients. DATA SOURCES: We searched MEDLINE, PubMed, Embase, Cochrane Library, and unpublished sources, from inception to February 27, 2024. STUDY SELECTION: We included randomized controlled trials (RCTs) of critically ill adult patients randomized to VL compared with DL for endotracheal intubation. DATA EXTRACTION: Reviewers screened abstracts, full texts, and extracted data independently and in duplicate. We pooled data using a random-effects model, assessed risk of bias using the modified Cochrane tool and certainty of evidence using the Grading Recommendations Assessment, Development, and Evaluation approach. We pre-registered the protocol on PROSPERO (CRD42023469945). DATA SYNTHESIS: We included 20 RCTs (n = 4569 patients). Compared with DL, VL probably increases first pass success (FPS) (relative risk [RR], 1.13; 95% CI, 1.06-1.21; moderate certainty) and probably decreases esophageal intubations (RR, 0.47; 95% CI, 0.27-0.82; moderate certainty). VL may result in fewer aspiration events (RR, 0.74; 95% CI, 0.51-1.09; low certainty) and dental injuries (RR, 0.46; 95% CI, 0.19-1.11; low certainty) and may have no effect on mortality (RR, 0.97; 95% CI, 0.88-1.07; low certainty) compared with DL. CONCLUSIONS: In critically ill adult patients undergoing intubation, the use of VL, compared with DL, probably leads to higher rates of FPS and probably decreases esophageal intubations. VL may result in fewer dental injuries as well as aspiration events compared with DL with no effect on mortality. [ABSTRACT FROM AUTHOR]

Extracorporeal membrane oxygenation (ECMO) support of critically ill pediatric patients is associated with increased risk of thromboembolic events, and unfractionated heparin is used commonly for anticoagulation. Given reports of acquired antithrombin (AT) deficiency in this patient population and associated concern for heparin resistance, AT activity measurement and off‐label AT replacement have become common in pediatric ECMO centers despite limited optimal dosing regimens. We conducted a retrospective cohort study of pediatric ECMO patients (0 to <18 years) at a single academic center to characterize the pharmacokinetics (PK) of human plasma‐derived AT. We demonstrated that a two‐compartment turnover model appropriately described the PK of AT, and the parameter estimates for clearance, central volume, intercompartmental clearance, peripheral volume, and basal AT input under non‐ECMO conditions were 0.338 dL/h/70 kg, 38.5 dL/70 kg, 1.16 dL/h/70 kg, 40.0 dL/70 kg, and 30.4 units/h/70 kg, respectively. Also, ECMO could reduce bioavailable AT by 50% resulting in 2‐fold increase of clearance and volume of distribution. To prevent AT activity from falling below predetermined thresholds of 50% activity in neonates and 80% activity in older infants and children, we proposed potential replacement regimens for each age group, accompanied by therapeutic drug monitoring.

Background: Feeding intolerance is common in critically ill patients and can lead to malnutrition. Prokinetic agents may be used to enhance the uptake of nutrition. However, the evidence on the effectiveness and safety of prokinetic agents is sparse, and there is a lack of data on their use in intensive care units (ICU). Methods: We will conduct an international 14‐day inception cohort study of 1000 acutely admitted adult ICU patients. Data will be collected from ICU admission and daily during ICU stay for up to 90 days. The primary outcome will be the proportion of ICU patients who receive prokinetic agents. Secondary outcomes include mortality, days alive without life support, days alive out of ICU, days alive out of hospital (all within 90 days) and the number of patients with one or more serious adverse events. Results: We will present data on the use of prokinetic agents descriptively and use Cox regressions with death and ICU discharge as competing events to evaluate the association between patient characteristics and the use of prokinetic agents. We will use extended Cox models with time‐varying covariates and linear regression models to assess the associations between the use of prokinetic agents and the secondary outcomes. Conclusion: The outlined international cohort study will provide valuable epidemiological data on the use of prokinetic agents in adult, acutely admitted ICU patients. [ABSTRACT FROM AUTHOR]

Background: Frailty is strongly correlated with mortality in intensive care unit patients, yet routine screening among intensive care patients is rarely performed. The aim of this study is to assess frailty and health‐related quality of life (HRQoL) in patients before intensive care admission and to compare this with outcomes after 3 and 12‐months. The Clinical Frailty Scale and EQ‐5D‐5L will be used to assess frailty and HRQoL, respectively. Methods: This is an ongoing, prospective observational study including patients from five Norwegian ICU's. Inclusion criteria are patients aged ≥65 years requiring invasive mechanical ventilation for ≥24 h. The Clinical Frailty Scale and EQ‐5D‐5L are administered at baseline (before critical illness) and at 3‐ and 12‐months post‐inclusion. Additional data collected includes patient characteristics, ICU treatment details, illness severity and mortality. The EQ‐5D‐5L will be compared to Norwegian population norms and assessed for measurement properties. Results: Inclusion started July 2022 and will be stopped at 350 patients. The study will be completed in 2025. Conclusion: The study will assess the feasibility and measurement properties of the Clinical Frailty Scale and EQ‐5D‐5L in ICU survivors by telephone at long‐term follow‐up study and will give additional information on the frailty and HRQoL of intensive care survivors. Clinical trial registration: The study is registered in ClinicalTrials.gov NCT06012942. Protocol version 2.7.1, 19.05.2023. [ABSTRACT FROM AUTHOR]

Background: Previous findings support the claim intensive care unit (ICU) patients have a higher rate of comorbidities and reduction of health‐ and functional status compared with the normal population. Aim: In this prospective observational study, our aim was to determine those health‐related factors at the age of 31 years which were associated with a later critical illness among previously un‐hospitalized individuals by exploring data obtained from the Northern Finland Birth Cohort 1966 (NFBC1966). Methods: NFBC1966 is a Finnish birth cohort, which includes 12,058 live births with expected dates of delivery during 1966. The study was conducted among cohort participants who had not been hospitalized for any reason before the cohort follow‐up visit at the age of 31. The study group included NFBC1966 participants who were admitted to the ICU of the Oulu University Hospital. The control group included participants who were treated for any reason in regular hospital wards. The data considering the participants' health status and behavior at the age of 31 were collected from the NFBC1966 database. The gathering of ICU and hospitalization data was concluded on December 31, 2016. Results: 849 NFBC1966 participants met the inclusion criteria: 69 were treated in the ICU (study group) and 780 on regular hospital wards (controls). In the study group, the rate of neurological diseases (26% vs. 16%, 95% CI: −21.8%, −0.2%), malignancy (3% vs. 0.7%, 95% CI: −9.7%, 0.0%), alcohol abuse (4.5% vs. 1%, 95% CI: −11.5%, −0.3%) and smoking (77% vs. 65%, 95% CI: −21.6%, −0.3%) were higher compared with the control group. The patients in the ICU group were also more prone to violent injuries, (17% vs. 7%, 95% CI: −20.2%, −1.9%), practiced less hard physical activity (65% vs. 78%, 95% CI: 2.1%, 25.3%) and had lower maximal muscle strength according to the hand grip test (30 vs. 34 kg, 95% CI: −8.2, 8.6 kg). Conclusions: In this study examining previously un‐hospitalized patients, the main factors associated with future critical illness were neurological comorbidities, malignancy, alcohol misuse, smoking, low maximum muscle strength, and less frequent physical exercise compared with those with hospitalization not requiring ICU admission.

Background: Delirium is an acute and fluctuating disturbance in attention, awareness, and cognition, commonly observed in hospital settings, particularly among older adults, critically ill and surgical patients. Delirium poses significant challenges in patient care, leading to increased morbidity, mortality, prolonged hospital stays, and functional decline. Aim: The aim of this review is to map existing evidence on delirium diagnostic tools suitable for use in patients treated surgically due to hip fracture, to inform clinical practice and enhance patient care protocols in the postoperative setting. Method: We will conduct a scoping review on delirium diagnostic tools used for adult patients in the postoperative setting according to the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses extension for Scoping Reviews (PRISMA‐ScR). Eligibility criteria encompass all languages, publications dates, and study designs, with exception of case‐reports. We will systematically search multiple databases and include unpublished trials, ensuring a comprehensive review based on a predefined protocol. Results: Results will be presented descriptively, with supplementary tables and graphs. Studies will be grouped by design, surgical specialties, and diagnostic tools to identify potential variations. Conclusion: This scoping review will provide an overview of existing delirium diagnostic tools used in the postoperative setting and highlight knowledge‐gaps to support future research. Due to the large number of patients affected by postoperative delirium, evidence mapping is much needed to facilitate evidence‐based practice. [ABSTRACT FROM AUTHOR]

Purpose Introduction of new medications to health-system formularies is often not accompanied by assessments of their clinical impact on the local patient population. The growing availability of electronic health record (EHR) data and advancements in pharmacoepidemiology methods offer institutions the opportunity to monitor the medication implementation process and assess clinical effectiveness in the local clinical context. In this study, we applied novel causal inference methods to evaluate the effects of a formulary policy introducing tocilizumab therapy for critically ill patients with coronavirus disease 2019 (COVID-19). Methods We conducted a medication use evaluation utilizing EHR data from patients admitted to a large medical center during the 6 months before and after implementation of a formulary policy endorsing the use of tocilizumab for treatment of COVID-19. The impact of tocilizumab on 28-day all-cause mortality was assessed using a difference-in-differences analysis, with ineligible patients serving as a nonequivalent control group, and a matched analysis guided by a target trial emulation framework. Safety endpoints assessed included the incidence of secondary infections and liver enzyme elevations. Our findings were benchmarked against clinical trials, an observational study, and a meta-analysis. Results Following guideline modification, tocilizumab was administered to 69% of eligible patients. This implementation was associated with a 3.1% absolute risk reduction in 28-day mortality (odds ratio, 0.86; number needed to treat to prevent one death, 32) attributable to the inclusion of tocilizumab in the guidelines and an additional 8.6% absolute risk reduction (odds ratio, 0.65; number needed to treat to prevent one death, 12) linked to its administration. These findings were consistent with estimates from published literature, although the effect estimates from the difference-in-differences analysis exhibited imprecision. Conclusion Evaluating formulary management decisions through novel causal inference approaches offers valuable estimates of clinical effectiveness and the potential to optimize the impact of new medications on population outcomes.

Purpose Evidence has suggested that clevidipine may provide faster blood pressure (BP) reduction with less volume than nicardipine in stroke and cardiothoracic surgery patients, but its use in hypertensive crises has not been well established. The primary objective of this study was to compare the treatment success of clevidipine and nicardipine in hypertensive crisis. Methods This was a multicenter, retrospective cohort study including patients who received either clevidipine or nicardipine for treatment of hypertensive crisis. The primary outcome was the time from infusion start to attainment of goal BP, defined as the higher value of the guideline-directed 25% reduction in BP or the physician-ordered goal. Secondary outcomes were the time from infusion start to guideline-directed 25% reduction in BP, drug and total volume intake, the time from order entry to BP goal attainment, the number of BP and heart rate excursions, intensive care unit (ICU) length of stay, and study medication cost. Results In total, 182 patients were included in the study (103 receiving nicardipine and 79 receiving clevidipine). Time to goal BP was similar between the groups (35 vs 33 minutes for clevidipine vs nicardipine, respectively; P = 0.37). Time to guideline-directed 25% reduction was also similar (P = 0.42). Volume from study drug was significantly less with clevidipine (222 vs 518 mL; P = 0.01); however, the total volume received in the ICU was similar (3,370 vs 3,383 mL; P = 0.43). Percent time in the goal BP range was similar (43.1% vs 42.3%). The cost of clevidipine was $199.37 per vial (based on the average wholesale price as of June 2023). This cost was 682% higher than that for a bag of nicardipine. Conclusion Time to goal BP was similar for clevidipine and nicardipine in this population. Any decreases in medication-associated volume with clevidipine were no longer evident when all volume sources were considered. These results show that clevidipine may not provide meaningful benefit in this heterogenous population. The difference in cost does not seem justified given the lack of improvement in clinically relevant outcomes. [ABSTRACT FROM AUTHOR]

Background: Pre-existing and new-onset atrial fibrillation (NOAF) is a common arrhythmia in COVID-19 patients and is related to increased mortality. CHA2DS2-VASc score was initially developed to evaluate thromboembolic risk in patients with AF. Moreover, it predicted adverse outcomes in other clinical conditions, including SARS-CoV-2 infection. We aimed to evaluate the association of CHA2DS2-VASc with NOAF, ICU length of stay (LOS) and mortality in critically ill COVID-19 patients. We also examined the relationship of NOAF with mortality. We reviewed the literature to describe the link between cardiovascular risk factors and inflammatory response of severe COVID-19. Methods and results: We retrospectively studied 163 COVID-19 patients admitted to a level 3 general ICU from March 2020 to April 2022. Patients were of advanced age (median 64 years, IQR 56.5-71) and the majority of them were male (67.5%). Regarding NOAF, we excluded 12 patients with AF history. In this group, CHA2DS2VASc score was significantly elevated (3 IQR (1-4) versus 1 IQR (1-2.75), p = 0.003). Specifically, three components of CHA2DS2VASc were notably increased: age (p < 0.001), arterial hypertension (p = 0.042) and stroke (p = 0.047). ICU mortality was raised in the NOAF group [75.8% versus 34.8%, p < 0.001 OR 5.87, 95% CI (2.43, 14.17)]. This was significant even after adjusting for ICU clinical scores (APACHE II and SOFA). About mortality in the entire sample, survivors were younger (p = 0.001). Non-survivors had greater APACHE II (p = 0.04) and SOFA (p = 0.033) scores. CHA2DS2VASc score was positively associated with mortality [p = 0.031, OR 1.28, 95% CI (1.03, 1.6)]. ICU length of stay was associated with mortality (p = 0.016) but not with CHA2DS2VASc score (p = 0.842). Conclusions: NOAF and CHA2DS2VASc score were associated with higher mortality in COVID-19 ICU patients. CHA2DS2VASc score was also associated with NOAF but not with ICU LOS. [ABSTRACT FROM AUTHOR]

Alzheimer's disease (AD) patients admitted to intensive care units (ICUs) exhibit varying survival outcomes due to the unique challenges in managing AD patients. Stratifying patient mortality risk and understanding the criticality of nursing care are important to improve the clinical outcomes of AD patients. This study aimed to leverage machine learning (ML) and electronic health records (EHRs) only consisting of demographics, disease history, and routine lab tests, with a focus on nursing care, to facilitate the optimization of nursing practices for AD patients. We utilized Medical Information Mart for Intensive Care III, an open-source EHR dataset, and AD patients were identified based on the International Classification of Diseases, Ninth Revision codes. From a cohort of 453 patients, a total of 60 features, encompassing demographics, laboratory tests, disease history, and number of nursing events, were extracted. ML models, including XGBoost, random forest, logistic regression, and multi-layer perceptron, were trained to predict the 30-day mortality risk. In addition, the influence of nursing care was analyzed in terms of feature importance using values calculated from both the inherent XGBoost module and the SHapley Additive exPlanations (SHAP) library. XGBoost emerged as the lead model with a high accuracy of 0.730, area under the curve (AUC) of 0.750, sensitivity of 0.688, and specificity of 0.740. Feature importance analyses using inherent XGBoost module or SHAP both indicated the number of nursing care within 14 days post-admission as an important denominator for 30-day mortality risk. When nursing care events were excluded as a feature, stratifying patient mortality risk was also possible but the model's AUC of receiver operating characteristic curve was reduced to 0.68. Nursing care plays a pivotal role in the survival outcomes of AD patients in ICUs. ML models can be effectively employed to predict mortality risks and underscore the importance of specific features, including nursing care, in patient outcomes. Early identification of high-risk AD patients can aid in prioritizing intensive nursing care, potentially improving survival rates. [ABSTRACT FROM AUTHOR]

Aim: To understand the status quo of multiprofessional and multidisciplinary collaboration for early mobilization of mechanically ventilated patients in Chinese ICUs and identify any factors that may influence this practice. Design: A multi‐centre cross‐sectional survey. Methods: From October to November 2022, the convenience sampling method was used to select ICU multiprofessional and multidisciplinary early mobility members (including physicians, nurses and physiotherapists) from 27 tertiary general hospitals in 14 provinces, cities and autonomous regions of China. They were asked to complete an author‐developed questionnaire on the status of collaboration and the Assessment of Inter‐professional Team Collaboration Scale. A multiple linear regression model was used to analyse the factors associated with the level of collaboration. Results: Physicians, nurses and physiotherapists mostly suffered from the lack of normative protocols, unclear division of responsibilities and unclear multiprofessional and multidisciplinary teams when using a collaborative approach to early activities. Multiple linear regression analysis showed that the number of ICU patients managed, the existence of norms and processes, the attitude of colleagues around them, the establishment of a team, communication methods and activity leaders were significant influences on the level of collaboration among members of the multiprofessional and multidisciplinary early activities. Conclusion: The collaboration of multiprofessional and multidisciplinary early activity members for mechanically ventilated patients in the ICU remains unclear, and the collaboration strategy needs to be constructed and improved, taking into account China's human resources and each region's economic development level. Impact: This study investigates the collaboration status of multiprofessional and multidisciplinary activity members from the perspective of teamwork, analyses the reasons affecting the level of collaboration and helps to develop better teamwork strategies to facilitate the implementation of early activities. Patient or Public Contribution: The participants in this study were multiprofessional and multidisciplinary medical staff who performed early activities for ICU patients. [ABSTRACT FROM AUTHOR]

This retrospective study aims to analyze the baseline characteristics and factors associated with poor outcomes in patients with necrotizing enterocolitis (NEC) complicating respiratory syncytial virus (RSV) infection. Using the Virtual Pediatric Systems data registry, patients under 2 years admitted to the pediatric intensive care unit (PICU) were screened. Patients with documented RSV infection and NEC, intestinal perforation, noninfectious gastroenteritis/colitis, or pneumatosis intestinalis occurring around the timing of RSV bronchiolitis diagnosis were included. Out of the screened patients, 41 were analyzed. Most patients (93%) were aged 30 days to 2 years, one-third had baseline anatomical cardiac defects, and 20% history of prematurity. Median PICU length of stay was 11.7 days. Seven patients died before hospital discharge. While not statistically significant, nonsurvivors tended to exhibit higher PRISM-3 scores, more acidemia, and lower systolic blood pressure. These findings emphasize the need for cautious assessment of gastrointestinal symptoms in critically ill patients with RSV infection. [ABSTRACT FROM AUTHOR]

Background: Delirium is a state of altered level of consciousness often leading to confusion, inattention, and changes to levels of cognition. Delirium increases average length of stay in the hospital and costs the US health care system approximately $148 billion each year in associated medical costs. Sleep hygiene is an important factor in delirium prevention for all hospitalized patients. Objectives: This quality improvement project was designed to increase implementation of an evidence-based sleep hygiene bundle in the neurocritical care population in order to decrease rates of hospital-acquired delirium. Methods: This project followed the Plan, Do, Study, Act (PDSA) framework to facilitate a continuous quality improvement intervention at amid-Atlantic academicmedical center in the neurocritical care population. The continuous quality improvement included the incorporation of "sleep" as a topic into the daily rounding checklist, thus optimizing the ability to improve adherence to a multicomponent sleep hygiene bundle. The intervention includes the preintervention-postintervention occurrences of delirium and use of the daily rounding checklist. Results: Nursing adherence to documentation of delirium assessments was high at approximately 99%. Following the intervention, there was a 41% decrease in the number of patients who screened positive for hospital-acquired delirium. Discussion: The improvement in cases of hospital-acquired delirium may be attributed to the project intervention. Recommendations for future interventions include analysis of training on sleep plans, focus on nursing education regarding delirium assessment tools, or a measure of staff and/or patient satisfaction related to the intervention.

Patients with serious illnesses often do not engage in discussions about end-of-life care decision-making, or do so reluctantly. These discussions can be useful in facilitating advance care planning and connecting patients to services such as palliative care that improve quality of life. Terror Management Theory, a social psychology theory stating that humans are motivated to resolve the discomfort surrounding their inevitable death, has been discussed in the psychology literature as an underlying basis of human decision-making and behavior. This paper explores how Terror Management Theory could be extended to seriously ill populations and applied to their healthcare decision-making processes and quality of care received.

BACKGROUND: This study sought to estimate the overall cumulative incidence and odds of Hospital-acquired venous thromboembolism (VTE) among critically ill children with and without exposure to invasive ventilation. In doing so, we also aimed to describe the temporal relationship between invasive ventilation and hospital-acquired VTE development. METHODS: We performed a retrospective cohort study using Virtual Pediatric Systems (VPS) data from 142 North American pediatric ICUs among children < 18 y of age from January 1, 2016-December 31, 2022. After exclusion criteria were applied, cohorts were identified by presence of invasive ventilation exposure. The primary outcome was cumulative incidence of hospital-acquired VTE, defined as limb/neck deep venous thrombosis or pulmonary embolism. Multivariate logistic regression was used to determine whether invasive ventilation was an independent risk factor for hospital-acquired VTE development. RESULTS: Of 691,118 children studied, 86,922 (12.4%) underwent invasive ventilation. The cumulative incidence of hospital-acquired VTE for those who received invasive ventilation was 1.9% and 0.12% for those who did not (P < .001). The median time to hospital-acquired VTE after endotracheal intubation was 6 (interquartile range 3-14) d. In multivariate models, invasive ventilation exposure and duration were each independently associated with development of hospital-acquired VTE (adjusted odds ratio 1.64 [95% CI 1.42-1.86], P < .001; and adjusted odds ratio 1.03 [95% CI 1.02-1.03], P < .001, respectively). CONCLUSIONS: In this multi-center retrospective review from the VPS registry, invasive ventilation exposure and duration were independent risk factors for hospital-acquired VTE among critically ill children. Children undergoing invasive ventilation represent an important target population for risk-stratified thromboprophylaxis trials. [ABSTRACT FROM AUTHOR]

Objectives: To evaluate echocardiographic parameters, especially the Tei index as a predictor of outcome in critically ill children on continuous renal replacement therapy (CRRT). Methods: This cohort study included all critically ill patients admitted at the Pediatric intensive care unit (PICU) and underwent CRRT. Functional echocardiography and Pediatric Risk of Mortality Index (PRISM) III were used to evaluate the participants. Both the Tei index and the Vasoactive inotropic score (VIS) were estimated. Results: The study included 35 patients with an age range of 6 mo to 14 y. The Tei indexes, VIS, and PRISM III were reported as predictors of mortality with a sensitivity of 88%, 83%, and 94% and a specificity of 73%, 79%, and 89% respectively. In survivors, the mean Tei index score, median VIS, and mean PRISM values were 0.44 ± 0.1, 3.8 (0–40), and 12.06 ± 3.35, respectively. However, in non-survivors, the mean Tei index, median VIS, and mean PRISM score were 0.59 ± 0.16, 0.60 (0–342.5), and 22.94 ± 8.93, respectively. Conclusions: The Tei index could be used as a predictor for poor outcomes in children receiving CRRT. It is correlated to the PRISM score and VIS. [ABSTRACT FROM AUTHOR]

Background: Short courses of antibiotics (7-10 days) are effective for uncomplicated gram-negative bloodstream infections (GN-BSI). However, prior studies have been limited to small cohorts of critically ill patients. Objective: The objective of this study was to evaluate the safety and efficacy of short courses of therapy compared with longer courses in patients admitted to the intensive care unit (ICU) with GN-BSI. Methods: Propensity-matched, retrospective cohort study of critically ill patients with GN-BSI. The primary outcome was a composite of 30-day mortality or 60-day relapse. Secondary endpoints were components of the composite, 30-day relapse, cure with or without adverse drug events (ADE), and ADEs. Regression analysis was performed to identify factors predictive of the composite outcome. Results: 225 patients were included in the propensity analysis, 145 in the long cohort and 80 in the short cohort. The primary outcome occurred in 3.8% of patients in the short group and 9.0% of patients in the long group (P = 0.24). There was no difference in 30-day mortality (3.8% vs 5.5%, P = 0.79), 60-day relapse (0% vs 3.4%, P = 0.23), or 30-day readmission (20% vs 22.8%, P = 0.76). ADEs were more common in the long group (47.2% vs 34.1%, OR 1.7, 95% CI 1.04-2.9), primarily attributable to diarrhea. Conclusion and Relevance: In critically ill patients with GN-BSI, there were no efficacy outcome differences in patients treated with a short course of antibiotics compared with longer. However, patients in the short group were less likely to experience ADE. These findings suggest that short courses of antibiotics are effective for GN-BSI in critically ill patients.

ABSTRACT Aims Methods Results Conclusions Patient Contribution Trial Registration To compare the individual and combined effects on 90‐day mortality among four critically ill survivor groups: normal (without ICU‐acquired delirium or ICU‐acquired weakness), delirium‐only (with ICU‐acquired delirium only), weakness‐only (with ICU‐acquired weakness only) and delirium–weakness (combined ICU‐acquired delirium and weakness).A prospective cohort study consecutively recruited delirium‐free critically ill patients admitted to six medical ICUs at a university hospital. Delirium was assessed once daily for 14 days (or until death or ICU discharge) using the Confusion Assessment Method for the ICU. Participants who were discharged from the ICUs were assessed for weakness using the Medical Research Council scale. A summed score below 48 defines ICU‐acquired weakness. These survivors were evaluated again for 90‐day mortality. The study is reported using the STROBE checklist.Delirium developed in 107 (43.2%) participants during their first 14 days of ICU stay; 55 (22.2%) met criteria for weakness by ICU discharge. Participants with delirium were at increased risk for also developing ICU‐acquired weakness, and the 90‐day mortality was 18.2%. Independent of age and Acute Physiology and Chronic Health Evaluation II score at ICU admission, delirium‐only and weakness‐only were not associated with higher 90‐day mortality, while participants in the delirium–weakness group had a 3.69‐fold higher risk of death, compared to those who were normal during the ICU stay. A non‐significant interaction was found, suggesting the joint effect of delirium and weakness on mortality is not higher than the sum of both effects individually.Mortality is substantially high among critically ill survivors who experience both delirium and weakness, although no additive effect on mortality was observed when these conditions occur together. Our findings highlight the urgent need to optimise ICU care by prioritising the prevention, early identification and management of these two common ICU‐acquired conditions.Study participation and completion of all assessments.ClinicalTrials.gov identifier: NCT04206306 [ABSTRACT FROM AUTHOR]

Background: Ciprofol was approved for use in intensive care unit (ICU) patients requiring sedation during mechanical ventilation in July 2022. A pooled post-hoc analysis of phase 2 and phase 3 trials was conducted primarily to explore hypotension-free outcome in ICU patients who required mechanical ventilation and achieved the target light sedation goal at an early stage after being sedated with ciprofol or propofol. Methods: All eligible ICU patients who were expected to require sedation for 6–24 h were randomly assigned in a 2:1 ratio to either a ciprofol or propofol group. Ciprofol or propofol was initially infused at loading doses of 0.5 or 1.0 mg/kg followed by maintenance doses of 0.3 or 1.5 mg/kg/h. Ciprofol or propofol dosages were adjusted up or down at rates of 0.05–0.10 mg/kg/h or 0.25–0.50 mg/kg/h, respectively, to achieve the target light sedation (a Richmond Agitation-Sedation Scale of -2 to + 1). The primary post-hoc outcome was the hypotension-free rate in patients who had achieved the target sedation goal after 30-min administration of ciprofol or propofol. Results: In total, 174 patients were enrolled for pooled post-hoc analysis, of whom 116 and 58 were assigned to the ciprofol and propofol groups, respectively. The hypotension-free rate was significantly higher in patients who achieved the target sedation goal after 30-min administration of ciprofol (93.0% vs. 81.0%, P = 0.018), and especially in the subgroups of males and patients aged < 65 years. Multivariable analysis revealed that ciprofol treatment, a younger age and lower baseline body mass index were independent favorable predictors for a higher hypotension-free rate in patients who achieved the target sedation goal after 30-min of drug administration. Moreover, hypotension-free patients who reached the target sedation level after 30 min had a more favorable short-term prognosis including a lower incidence of drug-related treatment-emergent adverse events, shorter time to extubation and fewer dose adjustments of ciprofol or propofol (all P < 0.05). Conclusion: ICU patients undergoing mechanical ventilation and sedated with ciprofol had significantly lower rate of hypotension during the early phase of achieving light sedation during a 6–24 h period, leading to a more favorable short-term prognosis (within 24 h).

Background: Reduced muscle mass upon admission and development of muscle wasting are frequent in critically ill patients, and linked to unfavorable outcomes. Muscle ultrasound is a promising instrument for evaluating muscle mass. We summarized the findings of lower limb muscle ultrasound values and investigated how the muscle ultrasound parameters of the examination or the patient characteristics influence the results. Methods: Systematic review and meta-analysis of studies of lower limb ultrasound critically ill adults. PubMed, CINAHL, Embase, PEDro and Web of Science were searched. PRISMA guidelines were followed, and studies evaluated with the appropriate NIH quality assessment tool. A meta-analysis was conducted to compare the values at admission, short and long follow-up during ICU stay, and the association between baseline values and patient characteristics or ultrasound parameters was investigated with a meta-regression. Results: Sixty-six studies (3839 patients) were included. The main muscles investigated were rectus femoris cross-sectional area (RF-CSA, n = 33/66), quadriceps muscle layer thickness (n = 32/66), and rectus femoris thickness (n = 19/66). Significant differences were found in the anatomical landmark and ultrasound settings. At ICU admission, RF-CSA ranged from 1.1 [0.73–1.47] to 6.36 [5.45–7.27] cm2 (pooled average 2.83 [2.29–3.37] cm2) with high heterogeneity among studies (I2 = 98.43%). Higher age, higher BMI, more distal landmark and the use of probe compression were associated with lower baseline muscle mass. Conclusions: Measurements of muscle mass using ultrasound varied with reference to patient characteristics, patient position, anatomical landmarks used for measurement, and the level of compression applied by the probe; this constrains the external validity of the results and highlights the need for standardization.

Introduction: Chloride is the most abundant extracellular anion; however, abnormalities of serum chloride (dyschloremia) are often overlooked. This study aimed to study the association of dyschloremia with AKI and major adverse kidney events at Day 30 (MAKE30) in critically ill patients with sepsis. Materials and Methods: This prospective single‐center cohort study included adult patients with sepsis admitted in a tertiary care hospital in India. Patients with advanced chronic kidney disease, requiring dialysis at admission, or with hospital stay of less than 72 h were excluded. Hyperchloremia and hypochloremia were defined as chloride levels of > 110 mEq/L and < 95 mEq/L, respectively. The primary outcome measure was MAKE30—a composite of death, need for dialysis, or sustained loss of kidney function at Day 30. Results: In a cohort of 400 patients with a mean age of 60 (±15) years, AKI was seen in 301 (75.2%) and MAKE30 in 171 (42.8%). Hyperchloremia and hypochloremia were seen in 19.3% (n = 77) and 32.3% (n = 129), respectively, in the first 72 h of ICU stay. Hypochloremia, but not hyperchloremia, was independently associated with both MAKE30 (OR: 2.56, 95% CI: 1.13–5.79; p = 0.024) and new‐onset or worsening AKI (OR: 2.52, 95% CI: 1.17–5.41; p = 0.019). There was no association between hyperchloremia and either MAKE30 (OR: 1.07, 95% CI: 0.43–2.69; p = 0.882) or new‐onset/worsening AKI (OR: 0.89, 95% CI: 0.38–2.09; p = 0.781). Conclusion: Hypochloremia, but not hyperchloremia, was associated with MAKE30 in this cohort of critically ill patients with sepsis.

Background Methods Results Conclusions Editorial Comment Estimating equations for the assessment of glomerular filtration rate (GFR) have been poorly investigated in the critical care setting. We evaluated the agreement between the GFR measured with 51CrEDTA/iohexol (mGFR) and four estimating equations based on serum concentrations of creatine and/or cystatin C (eGFR) in two cohorts: critically ill patients and outpatients with normal‐to‐moderately reduced GFR.Forty‐three patients in the critical care group and 48 patients in the outpatient group were included. GFR was measured (mGFR) by plasma infusion clearance of 51Cr‐EDTA/iohexol (critical care group) and the single injection, one‐sample plasma 51Cr‐EDTA clearance technique (outpatients). The following estimating equations (eGFR) were used: the Chronic Kidney Disease Epidemiology Collaboration (CKD‐EPI) equation for creatinine (CKD‐EPICr), cystatin C (CKD‐EPICys C), creatinine+cystatin C (CKD‐EPICr + Cys C) and the Lund‐Malmö creatinine+cystatin C equation (LMCr + Cys C). Agreement between mGFR and eGFR was assessed by the Bland–Altman method and accuracy by calculating P30 and P10.In the critically ill group, the bias between the estimating equations and mGFR was −3.6 to 2.8 mL/min/1.73 m2, while the error was 121%–127% and the accuracy (P30) 33%–40%. In the outpatients, the bias between the estimating equations and mGFR was −13.0 to 7.6 mL/min/1.73 m2, while the error was 31%–41% and the accuracy (P30), 67%–96%.All four equations performed poorly in assessing GFR in the critically ill cohort with an unacceptably high error and low accuracy in contrast to the outpatient group. To accurately assess GFR in critically ill patients, GFR must be measured not estimated.For the assessment of glomerular filtration rate (GFR), it can be measured directly, but is frequently estimated using a point measure of serum creatinine concentration. In this study, ICU case GFR estimations, by different adjusted equations, done also for a cohort of outpatients, showed that these serum creatinine‐based estimations for ICU cases are not highly precise or reliable.

Background: Acute exacerbations of COPD (AECOPD) are common and significantly contribute to mortality in patients with COPD. Prognostic scores can assist clinicians in making tailored decisions to manage AECOPD. In the current study, we therefore aimed to evaluate the performance of the Noninvasive Ventilation Outcomes (NIVO) score, originally designed to assess in-ICU mortality, in predicting 1 year mortality and NIV failure in AECOPD. Methods: This retrospective study analyzed data from patients hospitalized for AECOPD requiring mechanical ventilation between January 1st, 2018, and December 31st, 2022. Mortality was assessed at the end of ICU stay and 1 year after admission, while NIV failure was defined as intubation or death without intubation. Results: Among 302 ICU admissions of COPD patients, 190 patients with AECOPD requiring mechanical ventilation were included. Of these, 44 (23%) died in the ICU, 62 out of 184 (34%) failed NIV, and 78 (41%) died within 1 year of admission. Patients who died in ICU or experienced NIV failure had more severe COPD and more impaired blood gas parameters at admission. The NIVO score demonstrated an AUC of 0.68 in predicting 1-year mortality and an AUC of 0.85 in predicting NIV failure. A NIVO score over 7 was associated with higher 1-year mortality and NIV failure (HR of 4.4 [1.8–10.9] and 41.6 [5.6–307.9], respectively). Conclusion: Beyond predicting in-ICU mortality, the NIVO-score is a reliable tool in predicting 1-year mortality and NIV failure in AECOPD. [ABSTRACT FROM AUTHOR]
