Abstract
OBJECTIVES To compare catheter-related outcomes of individuals who received a tunnelled femorally inserted central catheter (tFICC) with those who received a peripherally inserted central catheter (PICC) in the upper extremities. DESIGN A propensity-score matched cohort study. SETTING A 980-bed tertiary referral hospital in South West Sydney, Australia. PARTICIPANTS In-patients referred to the hospital central venous access service for the insertion of a central venous access device. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome of interest was the incidence of all-cause catheter failure. Secondary outcomes included the rates of catheters removed because of suspected or confirmed catheter-associated infection, catheter dwell and confirmed upper or lower extremity deep vein thrombosis (DVT). RESULTS The overall rate of all-cause catheter failure in the matched tFICC and PICC cohort was 2.4/1000 catheter days (95% CI 1.1 to 4.4) and 3.0/1000 catheter days (95% CI 2.3 to 3.9), respectively, and when compared, no difference was observed (difference -0.63/1000 catheter days, 95% CI -2.32 to 1.06). We found no differences in catheter dwell (mean difference of 14.2 days, 95% CI -6.6 to 35.0, p=0.910); or in the cumulative probability of failure between the two groups within the first month of dwell (p=0.358). No significant differences were observed in the rate of catheters requiring removal for confirmed central line-associated bloodstream infection (difference 0.13/1000 catheter day, 95% CI -0.36 to 0.63, p=0.896). Similarly, no significant differences were found between the groups for confirmed catheter-related DVT (difference -0.11 per 1000 catheter days, 95% CI -0.26 to 0.04, p=1.00). CONCLUSION There were no differences in catheter-related outcomes between the matched cohort of tFICC and PICC patients, suggesting that tFICCs are a possible alternative for vascular access when the veins of the upper extremities or thoracic region are not viable for catheterisation.

Abstract
OBJECTIVES There was no evidence regarding the relationship between septic shock and tracheal injury scores. Investigate whether septic shock was independently associated with tracheal injury scores in intensive care unit (ICU) patients with invasive ventilation. DESIGN Prospective observational cohort study. SETTING Our study was conducted in a Class III hospital in Hebei province, China. PARTICIPANTS Patients over 18 years of age admitted to the ICU between 31 May 2020 and 3 May 2022 with a tracheal tube and expected to be on the tube for more than 24 hours. PRIMARY AND SECONDARY OUTCOME MEASURES Tracheal injuries were evaluated by examining hyperaemia, ischaemia, ulcers and tracheal perforation by fiberoptic bronchoscope. Depending on the number of lesions, the lesions were further classified as moderate, severe or confluent. RESULTS Among the 97 selected participants, the average age was 56.6±16.5 years, with approximately 64.9% being men. The results of adjusted linear regression showed that septic shock was associated with tracheal injury scores (β: 2.99; 95% CI 0.70 to 5.29). Subgroup analysis revealed a stronger association with a duration of intubation ≥8 days (p=0.013). CONCLUSION Patients with septic shock exhibit significantly higher tracheal injury scores compared with those without septic shock, suggesting that septic shock may serve as an independent risk factor for tracheal injury.

Abstract
INTRODUCTION Fever treatment is commonly applied in patients with sepsis but its impact on survival remains undetermined. Patients with respiratory and haemodynamic failure are at the highest risk for not tolerating the metabolic cost of fever. However, fever can help to control infection. Treating fever with paracetamol has been shown to be less effective than cooling. In the SEPSISCOOL pilot study, active fever control by external cooling improved organ failure recovery and early survival. The main objective of this confirmatory trial is to assess whether fever control at normothermia can improve the evolution of organ failure and mortality at day 60 of febrile patients with septic shock. This study will compare two strategies within the first 48 hours of septic shock: treatment of fever with cooling or no treatment of fever. METHODS AND ANALYSIS SEPSISCOOL II is a pragmatic, investigator-initiated, adaptive, multicentre, open-label, randomised controlled, superiority trial in patients admitted to the intensive care unit with febrile septic shock. After stratification based on the acute respiratory distress syndrome status, patients will be randomised between two arms: (1) cooling and (2) no cooling. The primary endpoint is mortality at day 60 after randomisation. The secondary endpoints include the evolution of organ failure, early mortality and tolerance. The target sample size is 820 patients. ETHICS AND DISSEMINATION The study is funded by the French health ministry and was approved by the ethics committee CPP Nord Ouest II (Amiens, France). The results will be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT04494074.

Abstract
Background and aim Assessing the knowledge of healthcare professionals regarding the Airway, Breathing, Circulation, Disability, and Exposure (ABCDE) approach is crucial since it prioritizes the initial assessment and treatment of patients who are critically ill, regardless of the underlying cause or their age. Since adherence requires knowledge, this study aimed to evaluate the knowledge level of the ABCDE approach among healthcare professionals. Methods This cross-sectional study among healthcare professionals was performed from April to August 2023 in Taif City, Saudi Arabia. The study included healthcare professionals employed in departments exposed to patients with critical illnesses and excluded those from other specialties and individuals from outside Taif City. Data was collected via Google Forms using a previously validated questionnaire designed to assess the ABCDE approach knowledge among healthcare professionals. Statistical analysis was conducted using IBM SPSS, version 26. Results The study included 242 healthcare professionals with a mean (SD) age of 35.77 (9.93) years. About half of the participants were female (52.5%) nurses (50.8%) and had been working in intensive care units (ICU) and neonate intensive care units (NICU) (41.4%). The mean (SD) of the participants' working experience was 9.28 (8.295) years. The overall mean test score was 52.94 % (SD 16.27). The mean knowledge score among males was significantly higher than females (56.37% vs. 49.85%, respectively) (p-value= 0.001). The mean knowledge score was significantly higher among medical specialists and residents (63.308% and 55.67%) than among nurses (46.34%) (p-value <0.001). Attending an advanced trauma life support course and theoretical lecture significantly impacted the total knowledge score among the participants (p-values= 0.001 and <0.001, respectively). The total knowledge significantly increased with age (r: 0.265, p-value <0.001). Years of experience correlated with total knowledge score; with increasing years of experience, the total knowledge was significantly increased (r: 0.248, p-value <0.001). Conclusion The ABCDE approach is a valuable tool for the initial examination and treatment of patients in acute medical and surgical emergencies. The findings indicate that there is a need for further awareness programs and training on the ABCDE approach, as the total knowledge score among healthcare professionals was found to be suboptimal. Further research is needed to assess the association between knowledge level and clinical performance in different healthcare settings within Saudi Arabia.

Abstract
In the Philippines, acute cerebrovascular disease is a common neurologic complication in coronavirus disease 2019 (COVID-19) patients. Because of sedation and limited neurological examination, the diagnosis of stroke in critically ill patients with COVID-19 may be delayed. This retrospective analysis was done on the medical records of adult patients with critical COVID-19 in 2021-2022 who were brought to a tertiary hospital in the Philippines, placed on mechanical ventilation, and later discovered to have had an ischemic or hemorrhagic stroke while under deep sedation. The study aimed to explore the delayed diagnosis of cerebrovascular disease clinically concealed by deep sedation and emphasizes the importance of a collaborative, multi-specialty approach to managing such patients. There were nine patients with strokes discovered on imaging after deep sedation due to severe COVID-19 infection. The median age of the cases was 63 years, and 55.5% (n=5) were males. Three of the nine patients had an ischemic stroke with hemorrhagic conversion, three with ischemic infarction, and the other three had a primary intracerebral hemorrhage. This series shows a pattern of delayed diagnosis of cerebrovascular disease clinically concealed by deep sedation that was essential in managing acute respiratory distress syndrome in the background of severe COVID-19 infection before the emergence of severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) variants and the discovery of COVID-19 vaccines. The study demonstrates the significance of managing this unique population of patients in a collaborative and multi-specialty manner. With the continuing threat of SARS-CoV-2 and its variants, there is a need to strike a balance between the risks of ischemic and hemorrhagic stroke in COVID-19 infection and the care of this patient population.

A prospective observational vignette-based study to determine the cognitive-behavioural effects of rapid diagnostic PCR-based point-of-care test results on antibiotic cessation in ICU infections. BMJ Open 2023; 13:e073577. [PMID: 37989388 PMCID: PMC10668237 DOI: 10.1136/bmjopen-2023-073577] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2023] [Accepted: 10/19/2023] [Indexed: 11/23/2023] Open
Abstract
OBJECTIVES Point-of-care tests (POCTs) for infection offer accurate rapid diagnostics but do not consistently improve antibiotic stewardship (ASP) of suspected ventilator-associated pneumonia. We aimed to measure the effect of a negative PCR-POCT result on intensive care unit (ICU) clinicians' antibiotic decisions and the additional effects of patient trajectory and cognitive-behavioural factors (clinician intuition, dis/interest in POCT, risk averseness). DESIGN Observational cohort simulation study. SETTING ICU. PARTICIPANTS 70 ICU consultants/trainees working in UK-based teaching hospitals. METHODS Clinicians saw four case vignettes describing patients who had completed a course of antibiotics for respiratory infection. Vignettes comprised clinical and biological data (ie, white cell count, C reactive protein), varied to create four trajectories: clinico-biological improvement (the 'improvement' case), clinico-biological worsening ('worsening'), clinical improvement/biological worsening ('discordant clin better'), clinical worsening/biological improvement ('discordant clin worse'). Based on this, clinicians made an initial antibiotics decision (stop/continue) and rated confidence (6-point Likert scale). A PCR-based POCT was then offered, which clinicians could accept or decline. All clinicians (including those who declined) were shown the result, which was negative. Clinicians updated their antibiotics decision and confidence. MEASURES Antibiotics decisions and confidence were compared pre-POCT versus post-POCT, per vignette. RESULTS A negative POCT result increased the proportion of stop decisions (54% pre-POCT vs 70% post-POCT, χ2(1)=25.82, p<0.001, w=0.32) in all vignettes except improvement (already high), most notably in discordant clin worse (49% pre-POCT vs 74% post-POCT). In a linear regression, factors that significantly reduced clinicians' inclination to stop antibiotics were a worsening trajectory (b=-0.73 (-1.33, -0.14), p=0.015), initial confidence in continuing (b=0.66 (0.56, 0.76), p<0.001) and involuntary receipt of POCT results (clinicians who accepted the POCT were more inclined to stop than clinicians who declined it, b=1.30 (0.58, 2.02), p<0.001). Clinician risk averseness was not found to influence antibiotic decisions (b=-0.01 (-0.12, 0.10), p=0.872). CONCLUSIONS A negative PCR-POCT result can encourage antibiotic cessation in ICU, notably in cases of clinical worsening (where the inclination might otherwise be to continue). This effect may be reduced by high clinician confidence to continue and/or disinterest in POCT, perhaps due to low trust/perceived utility. Such cognitive-behavioural and trajectorial factors warrant greater consideration in future ASP study design.

Abstract
OBJECTIVE To clarify the reasons for consultation, advice sought by frontline physicians and relationship between the patient's pathology and the type of advice provided to guide the future development of telecritical care services. DESIGN Secondary analysis of transcripts of telephone calls originally recorded for quality control purposes was conducted using a thematic content analysis. The calls were conducted between December 2019 and April 2021 (total cases: 70; total time: ~15 hour). SETTINGS Intensivists provided consultation services to frontline physicians at secondary care institutions in the Kansai and Chubu regions. PARTICIPANTS Non-intensive care frontline physicians working in five secondary care institutions in the Kansai and Chubu regions and intensivists providing a consultation service (n=26). INTERVENTIONS Not applicable. PRIMARY AND SECONDARY OUTCOME MEASURES The main outcome was the themes emerging from the language used during telephone and video consultations, indicating the gap filled by the telecritical care service. FINDINGS We analysed 70 cases and approximately 15 hours of anonymised audio data. We identified the following reasons for consultation: 'lack of competence in treatment and diagnostic testing' and 'lack of access to consultation in their own hospital'. Frontline physicians most often sought advice related to 'treatment', followed by 'patient triage and transfer', 'diagnosis' and 'diagnostic testing and evaluation'. Regarding the relationship between the patient's pathology and type of advice provided, the most commonly sought advice by frontline physicians varied based on the patient's pathology. CONCLUSION This study explored the characteristics of 70 telecritical sessions and identified the reasons for and nature of the consultations. These findings can be used to guide the future provision and scale up of telecritical services.

Abstract
OBJECTIVES This study sought to estimate the effect of dexmedetomidine (DEX) administration on mortality in critically ill patients with acute kidney injury (AKI). DESIGN A retrospective cohort study. SETTING The study sourced its data from the Multiparameter Intelligent Monitoring in Intensive Care Database IV (MIMIC-IV), a comprehensive database of intensive care unit patients. PARTICIPANTS A total of 15 754 critically ill patients with AKI were enrolled from the MIMIC-IV database. PRIMARY AND SECONDARY OUTCOME Primary outcome was in-hospital mortality and secondary outcome was 180-day mortality. RESULTS 15 754 critically ill AKI patients were included in our analysis. We found that DEX use decreased in-hospital mortality risk by 38% (HR 0.62, 95% CI 0.55 to 0.70) and 180-day mortality risk by 23% (HR 0.77, 95% CI 0.69 to 0.85). After adjusting for confounding factors, DEX can reduce all three stages of AKI in in-hospital mortality. CONCLUSIONS Our retrospective cohort study suggests that DEX significantly correlates with decreased risk-adjusted in-hospital and 180-day mortality in critically ill AKI patients. Nonetheless, future randomised controlled trials are warranted to validate our findings.

Abstract
INTRODUCTION Simulation-based studies indicate that crisis checklist use improves management of patients with critical conditions in the emergency department (ED). An interview-based study suggests that use of an emergency manual (EM)-a collection of crisis checklists-improves management of clinical perioperative crises. There is a need for in-depth prospective studies of EM use during clinical practice, evaluating when and how EMs are used and impact on patient management. METHODS AND ANALYSIS This 6-month long study prospectively evaluates a digital EM during management of priority 1 patients in the Skåne University Hospital at Lund's ED. Resuscitation teams are encouraged to use the EM after a management plan has been derived ('Do-Confirm'). The documenting nurse activates and reads from the EM, and checklists are displayed on a large screen visible to all team members. Whether the EM is activated, and which sections are displayed, are automatically recorded. Interventions performed thanks to Do-Confirm EM use are registered by the nurse. Fifty cases featuring such interventions are reviewed by specialists in emergency medicine blinded to whether the interventions were performed prior to or after EM use. All interventions are graded as indicated, of neutral relevance or not indicated. The primary outcome measures are the proportions of interventions performed thanks to Do-Confirm EM use graded as indicated, of neutral relevance, and not indicated. A secondary outcome measure is the team's subjective evaluation of the EM's value on a Likert scale of 1-6. Team members can report events related to EM use, and information from these events is extracted through structured interviews. ETHICS AND DISSEMINATION The study is approved by the Swedish Ethical Review Authority (Dnr 2022-01896-01). Results will be published in a peer-reviewed journal and abstracts submitted to national and international conferences to disseminate our findings. TRIAL REGISTRATION NUMBER NCT05649891.

Abstract
Introduction Venovenous extracorporeal membrane oxygenation (V-V ECMO) can be considered in critically ill patient in severe pulmonary failure. However, the mobilization of patients on V-V ECMO can be challenging due to logistic and safety concerns. This study aimed to investigate whether 30 days survival was improved in patients who were mobilized during V-V ECMO support. Methods We conducted a retrospective cohort all-comer study that included all patients cannulated for V-V ECMO at a single center. Patients with a V-V ECMO duration below 24 h were excluded from the analysis. The patients were grouped based on the ICU mobility scale documented during V-V ECMO support. The primary endpoint was 30 days survival, and secondary endpoints included weaning from ECMO and mechanical ventilation, as well as hospital survival. Results A total of 343 patients were included in the study, with a median age of 56 years and 32% were female. Among them, 28% had chronic lung disease. The ICU mobilization scale ≥2 during ECMO was documented in 62/343 (18%) patients. There were no significant differences in age, gender and preexisting lung disease. Duration of ICU stay (13.1 vs. 15.6 days), time on ECMO (186 vs. 190 h) and mechanical ventilation (11.2 vs. 13.6 days) were slightly shorter in patients with ICU mobility scale <2 compared to those with ≥2 (all p = 0.0001). However, patients with ICU mobilization scale ≥2 showed significantly better 30 days survival (71.0 vs. 48.0%, OR 2.6 (1.5 to 4.8), p = 0.0012) compared to those with <2. In the ≥2 mobility scale group, a significantly higher number of patients were successfully weaned from the ventilator (61.3 vs. 46.6%, OR 1.8 (1.0 to 3.2), p = 0.049). A stronger correlation was observed between more intense mobilizations, such as being in a standing position (OR 5.0 (1.7 to 14.0), p = 0.0038), and higher 30 days survival. Conclusion The findings of this study suggest that active mobilization during V-V ECMO support is associated with improved 30 days survival and successful weaning from the respirator. Incorporating mobilization as part of the therapeutic approach during ECMO support may offer potential benefits for critically ill patients.

Abstract
Blood pressure management is a critical aspect of patient care, particularly in surgical and critical care settings. Closed-loop systems, which utilize real-time data and feedback to adjust treatment interventions, have gained attention for their potential to enhance blood pressure control. This review explores the application of closed-loop systems in blood pressure management. We discuss various closed-loop approaches, including their mechanisms, benefits, and limitations. By harnessing real-time patient data and feedback, closed-loop systems can tailor interventions dynamically, thus enhancing blood pressure regulation. Additionally, we examine the integration of advanced monitoring technologies and artificial intelligence algorithms in closed-loop systems. The review highlights recent studies and their findings, emphasizing the evolving landscape of closed-loop blood pressure management across different clinical scenarios. From the perioperative period to critical care settings, closed-loop systems hold the potential to optimize patient outcomes by precisely adjusting vasopressor administration in response to continuous blood pressure fluctuations. By providing insights into the current state of closed-loop systems for blood pressure control, this review offers a comprehensive overview of their potential contributions to improved patient outcomes and future directions for research and implementation.

Abstract
While macrocytic anemia is common in vitamin B12 deficiency, rarely, pancytopenia and hemolytic anemia can occur. Homocysteine levels are elevated in severe B12 deficiency, and this is linked to thrombus formation with potentially life-threatening complications. We present a patient with severe vitamin B12 deficiency complicated by hyperhomocysteinemia and obstructive shock from pulmonary embolism. A 56-year-old male with no medical history presented to the hospital with altered mentation. The patient's family stated he was experiencing bilateral paresthesias of his lower extremities, progressive depression, anxiety, and insomnia. Initial vitals were blood pressure of 76/36, heart rate of 70 beats per minute, respiratory rate of 14, and temperature of 36.3 degrees Celsius. He was intubated due to severe encephalopathy. Relevant labs indicated severe macrocytic anemia, thrombocytopenia, decreased B12 levels, elevated methylmalonic acid, and elevated homocysteine. Imaging demonstrated a right common femoral vein thrombosis and subsegmental pulmonary emboli. Peripheral blood smear revealed schistocytes, anisopoikilocytosis, and decreased platelet count. The patient required fluid resuscitation, antibiotics, and multiple blood products. Vitamin B12 was administered intramuscularly, which improved the anemia. Esophagogastroduodenoscopy (EGD) demonstrated gastritis. Gastric and duodenal biopsies were negative for Helicobacter pylori and celiac disease. He was negative for intrinsic factor (IF) antibodies but had elevated gastrin levels. An intravenous unfractionated heparin infusion was started when the platelet count was above 50000. The patient was extubated after seven days. Heparin was transitioned to apixaban and an inferior vena cava (IVC) filter was placed. Hyperhomocysteinemia is a known pro-thrombotic factor that can lead to the development of venous thromboembolism. B12 malabsorption can stem from inflammatory bowel disease, celiac disease, gastritis, pancreatic insufficiency, gastrectomy, gastric bypass surgery, or antibodies to IF. While this case showed gastritis and negative IF antibodies, gastrin levels were elevated, indicating a mixed picture. This highlights the challenge of definitively diagnosing pernicious anemia as the cause of vitamin B12 deficiency. Vitamin B12 deficiency may lead to critical illness in which thromboembolism develops secondary to hyperhomocysteinemia.

Abstract
OBJECTIVES Medical decision-making at the end of life is common and should be as patient-centred as possible. Our study investigates older adults' preferences towards three medical treatments that are frequently included in advance directive forms and their association with social, regional and health characteristics. SETTING A cross-sectional study using population-based data of wave 8 (2019/2020) of the Swiss component of the Survey of Health, Ageing and Retirement in Europe. PARTICIPANTS 1430 adults aged 58 years and older living in Switzerland. PRIMARY AND SECONDARY OUTCOME MEASURES Three questions on the preferences regarding cardiopulmonary resuscitation (CPR); life-prolonging treatment in case of high risk of permanent mental incapacity; reduced awareness (sedation) to relieve unbearable pain and symptoms. Their associations with individuals' social, regional and health characteristics. RESULTS Most older adults expressed a wish to receive CPR (58.6%) and to forgo life-prolonging treatment in case of permanent mental incapacity (92.2%). Most older adults also indicated that they would accept reduced awareness if necessary to receive effective treatment for pain and distressing symptoms (59.2%). Older adults' treatment preferences for CPR and life-prolonging treatment differed according to sex, age, partnership status, linguistic region and health status, while willingness to accept reduced awareness for effective symptom treatment was more similarly distributed across population groups. CONCLUSIONS Simultaneous preferences for CPR and refusal of life-prolonging treatment might appear to be conflicting treatment goals. Considering individuals' values and motivations can help clarify ambivalent treatment decisions. Structured advance care planning processes with trained professionals allows for exploring individuals' motivations and values and helps to identify congruent care and treatment goals.

Assessment of redundancy, methodological and reporting quality, and potential discrepancies of results of systematic reviews of early mobilisation of critically ill adults: a meta-research protocol. BMJ Open 2023; 13:e074615. [PMID: 37474166 PMCID: PMC10360432 DOI: 10.1136/bmjopen-2023-074615] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Accepted: 06/28/2023] [Indexed: 07/22/2023] Open
Abstract
INTRODUCTION Several systematic reviews (SRs) have been conducted to determine the effectiveness of early mobilisation in critically ill adults with heterogeneous methodology and results. Redundancy in conducting SRs, unclear justification when leading new SRs or updating, and discordant results of SRs on the same research question may generate research waste that makes it difficult for clinicians to keep up to date with the best available evidence. This meta-research aims to assess the redundancy, methodological and reporting quality, and potential reasons for discordance in the results reported by SRs conducted to determine the effectiveness of early mobilisation in critically ill adult patients. METHODS AND ANALYSIS A meta-research of early mobilisation SRs in critically ill adult patients will be conducted. A search of MEDLINE (Ovid), Embase (Ovid), CINAHL (EBSCOhost), Cochrane Library, Epistemonikos and other search resources will be conducted. Two independent reviewers will perform study selection, data extraction and quality appraisal. Discrepancies will be resolved by consensus or a third reviewer. The redundancy of SRs will be assessed by the degree of overlap of primary studies. In addition, the justification for conducting new SRs will be evaluated with the 'Evidence-Based Research' framework. The methodological quality of the SRs will be assessed with the A MeaSurement Tool to Assess systematic Reviews 2 tool, and the quality of the reports through compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. To assess the potential reasons for discordance in the results of the SRs considering divergence in results and their interpretation. ETHICS AND DISSEMINATION As meta-research, this study does not involve the participation of people whose rights may be violated. However, this overview will be developed rigorously and systematically to achieve valid and reliable results. The findings of this meta-research study will be presented at conferences and published in a peer-reviewed journal related to rehabilitation, critical care or research methodology.

Abstract
INTRODUCTION The BALANCE study is a randomised clinical trial (3626 participants) designed to assess the non-inferiority of 7 days (short-course) antibiotic therapy compared with 14 days of therapy for bacteraemia using the pragmatic endpoint of 90-day survival. Based on pilot study data, approximately 30% of enrolees will have a urinary tract infection (UTI) as the source of bacteraemia. METHODS AND ANALYSIS We aim to assess the non-inferiority of short-course antibiotic therapy for patients with bacteraemia UTIs.Participating sites in four countries will be invited to join this substudy. All participants of this substudy will be enrolled in the main BALANCE study. The intervention will be assigned and treatment administered as specified in the main protocol.We will include participants in this substudy if the probable source of their infection is a UTI, as judged by the site principal investigator, and they have a urine microscopy and culture indicative of a UTI. Participants will be excluded if they have an ileal loop, vesicoureteric reflux or suspected or confirmed prostatitis.The primary outcome is the absence of a positive culture on a test-of-cure urine sample collected 6-12 days after cessation of antimicrobials, with a non-inferiority margin of 15%. Secondary outcomes include the clinical resolution of infection symptoms at test-of-cure. ETHICS AND DISSEMINATION The study has been approved in conjunction with the main BALANCE study through the relevant ethics review process at each participating site. We will disseminate the results through the Australasian Society for Infectious Diseases, Canadian Critical Care Trials Group, the Association for Medical Microbiology and Infectious Diseases Canada Clinical Research Network (AMMI Canada CRN) and other collaborators.

Abstract
OBJECTIVES Although platelets have been linked to inflammatory development in sepsis, knowledge on their role as an indicator in sepsis treatment is scarce. Here, we investigated the association between time-dependent changes in platelet counts with mortality rates to reveal the role of platelets in sepsis therapy. DESIGN A retrospective cohort study. SETTING We screened the Medical Information Mart for Intensive Care (MIMIC-IV), a public database comprising data from critical care subjects at the Beth Israel Deaconess Medical Center (BIDMC) in Boston, Massachusetts, USA. PARTICIPANTS A total of 7981 patients, who were admitted to the BIDMC between 2008 and 2019, were analysed based on Sepsis-3 criteria from MIMIC-IV. PRIMARY AND SECONDARY OUTCOME MEASURES Primary and secondary outcomes included 30-day mortality after admission and length of intensive care unit (ICU) stay and hospitalisation, respectively. RESULTS Patients with ≤10% reduction in proportion of platelet counts were associated with significantly lower 30-day mortality (14.1% vs 23.5%, p<0.001, Kaplan-Meier analysis, p<0.0001). Multivariable analysis revealed that decreased platelet-count percentage ≤10% on day 4 after ICU admission was associated with lower probability of 30-day non-survival (OR=0.73, 95% CI 0.64 to 0.82, p<0.001). Patients in the ≤10% group had significantly shorter ICU stays than those in the >10% group (6.8 vs 7.5, p<0.001). Restricted cubic spline curves revealed that mortality rates decreased with increase in proportion of platelet counts. CONCLUSIONS A ≤10% decrease in platelet-count percentage among sepsis patients after treatments is independently associated with decreased 30-day mortality, suggesting that changes in proportion of platelet counts after treatments could be an indicator for assessing the therapeutic effects of sepsis.

Abstract
INTRODUCTION Sepsis, the leading cause of acute kidney injury (AKI), is associated with a high morbidity and mortality. Alkaline phosphatase (ALP) is an endogenous detoxifying enzyme. A recombinant human ALP compound, ilofotase alfa, showed no safety or tolerability concerns in a phase 2 trial. Renal function improvement over 28 days was significantly greater in the ilofotase alfa group. Moreover, a significant relative reduction in 28-day all-cause mortality of >40% was observed. A follow-up trial has been designed to confirm these findings. METHODS AND ANALYSIS This is a phase 3, global, multi-centre, randomised, double-blind, placebo-controlled, sequential design trial in which patients are randomly assigned to either placebo or 1.6 mg/kg ilofotase alfa. Randomisation is stratified by baseline modified Sequential Organ Failure Assessment (mSOFA) score and trial site. The primary objective is to confirm the survival benefit with ilofotase alfa by demonstrating a reduction in 28-day all-cause mortality in patients with sepsis-associated AKI requiring vasopressors. A maximum of 1400 patients will be enrolled at ∼120 sites in Europe, North America, Japan, Australia and New Zealand. Up to four interim analyses will take place. Based on predefined decision rules, the trial may be stopped early for futility or for effectiveness. In addition, patients with COVID-19 disease and patients with 'moderate to severe' chronic kidney disease are analysed as 2 separate cohorts of 100 patients each. An independent Data Monitoring Committee evaluates safety data at prespecified intervals throughout the trial. ETHICS AND DISSEMINATION The trial is approved by relevant institutional review boards/independent ethics committees and is conducted in accordance with the ethical principles of the Declaration of Helsinki, guidelines of Good Clinical Practice, Code of Federal Regulations and all other applicable regulations. Results of this study will determine the potential of ilofotase alfa to reduce mortality in critically ill patients with sepsis-associated AKI and will be published in a peer-reviewed scientific journal.

Abstract
OBJECTIVES To agree on the 'top 10' research priorities for environmentally sustainable perioperative practice. DESIGN Surveys and literature review; final consensus workshop using a nominal group technique. SETTING UK-based setting. PARTICIPANTS Healthcare professionals, patients, carers and the public. OUTCOME MEASURES Initial survey-suggested research questions; interim survey-shortlist of 'indicative' questions (the 20 most frequently nominated by patients, carers and the public, and healthcare professionals); final workshop-ranked research priorities. RESULTS Initial survey-1926 suggestions by 296 respondents, refined into 60 indicative questions. Interim survey-325 respondents. Final workshop-21 participants agreed the 'top 10': (1) How can more sustainable reusable equipment safely be used during and around the time of an operation? (2) How can healthcare organisations more sustainably procure (obtain) medicines, equipment and items used during and around the time of an operation? (3) How can healthcare professionals who deliver care during and around the time of an operation be encouraged to adopt sustainable actions in practice? (4) Can more efficient use of operating theatres and associated practices reduce the environmental impact of operations? (5) How can the amount of waste generated during and around the time of an operation be minimised? (6) How do we measure and compare the short-term and long-term environmental impacts of surgical and non-surgical treatments for the same condition? (7) What is the environmental impact of different anaesthetic techniques (eg, different types of general, regional and local anaesthesia) used for the same operation? (8) How should the environmental impact of an operation be weighed against its clinical outcomes and financial costs? (9) How can environmental sustainability be incorporated into the organisational management of operating theatres? (10) What are the most sustainable forms of effective infection prevention and control used around the time of an operation (eg, personal protective equipment, drapes, clean air ventilation)? CONCLUSIONS A broad range of 'end-users' have identified research priorities for sustainable perioperative care.

Abstract
OBJECTIVES Smartphone dispatch of volunteer responders for out-of-hospital cardiac arrest (OHCA) is implemented worldwide. While basic life support courses prepare participants to provide CPR, the courses rarely address the possibility of meeting a family member or relative in crisis. This study aimed to examine volunteer responders' provision of support to relatives of cardiac arrest patients and how relatives experienced the interaction with volunteer responders. DESIGN In this qualitative study, we conducted 16 semistructured interviews with volunteer responders and relatives of cardiac arrest patients. SETTING Interviews were conducted face to face and by video and recorded and transcribed verbatim. PARTICIPANTS Volunteer responders dispatched to cardiac arrests and relatives of cardiac arrest patients were included in the study. Participants were included from all five regions of Denmark. RESULTS A thematic analysis was performed with inspiration from Braun and Clarke. We identified three themes: (1) relatives' experiences of immediate relief at arrival of assistance, (2) volunteer responders' assessment of relatives' needs and (3) the advantage of being healthcare educated. CONCLUSIONS Relatives to out-of-hospital cardiac arrest patients benefited from volunteer responders' presence and support and experienced the mere presence of volunteer responders as supportive. Healthcare-educated volunteer responders felt confident and skilled to provide care for relatives, while some non-healthcare-educated volunteer responders felt they lacked the proper training and knowledge to provide emotional support for relatives. Future basic life support courses should include a lesson on how to provide emotional support to relatives of cardiac arrest patients.

Abstract
OBJECTIVES The Computer-Aided Risk Score for Mortality (CARM) estimates the risk of in-hospital mortality following acute admission to the hospital by automatically amalgamating physiological measures, blood tests, gender, age and COVID-19 status. Our aims were to implement the score with a small group of practitioners and understand their first-hand experience of interacting with the score in situ. DESIGN Pilot implementation evaluation study involving qualitative interviews. SETTING This study was conducted in one of the two National Health Service hospital trusts in the North of England in which the score was developed. PARTICIPANTS Medical, older person and ICU/anaesthetic consultants and specialist grade registrars (n=116) and critical outreach nurses (n=7) were given access to CARM. Nine interviews were conducted in total, with eight doctors and one critical care outreach nurse. INTERVENTIONS Participants were given access to the CARM score, visible after login to the patients' electronic record, along with information about the development and intended use of the score. RESULTS Four themes and 14 subthemes emerged from reflexive thematic analysis: (1) current use (including support or challenge clinical judgement and decision making, communicating risk of mortality and professional curiosity); (2) barriers and facilitators to use (including litigation, resource needs, perception of the evidence base, strengths and limitations), (3) implementation support needs (including roll-out and integration, access, training and education); and (4) recommendations for development (including presentation and functionality and potential additional data). Barriers and facilitators to use, and recommendations for development featured highly across most interviews. CONCLUSION Our in situ evaluation of the pilot implementation of CARM demonstrated its scope in supporting clinical decision making and communicating risk of mortality between clinical colleagues and with service users. It suggested to us barriers to implementation of the score. Our findings may support those seeking to develop, implement or improve the adoption of risk scores.

Abstract
OBJECTIVE To evaluate the association of 25-hydroxyvitamin D (25(OH)D) level on sepsis severity and risk of hospitalisation in emergency department (ED) septic patients when categorised as vitamin D insufficiency according to the level of 25(OH)D<30 ng/mL. DESIGN Cross-sectional observational study. SETTING A 900-bed academic tertiary hospital with an ED residency training programme in Bangkok, Thailand. PARTICIPANTS An observational study of 101 ED septic patients aged ≥18 years was conducted between March 2015 and September 2015. OUTCOME MEASURES The level of 25(OH)D was analysed and correlated with sepsis severity assessed by Acute Physiology Age Chronic Health Evaluation-II (APACHE-II) and Mortality in ED Sepsis (MEDS) scores, and the risk of hospitalisation. RESULTS One hundred and one patients were enrolled, with an average age of 68±18 years, 56% female, APACHE-II score of 14±6, MEDS score of 8±5 and 25(OH)D level was 19±11 ng/mL. The prevalence of vitamin D insufficiency in our ED septic patients was 87% and the admission rate was 88%. A significant association between 25(OH)D level and sepsis severity scores was found, which was measured by APACHE-II and MEDS scores (-0.29; 95% CI -0.41 to -0.17, p<0.001 and -0.15; 95% CI -0.25 to -0.06, p=0.002, respectively). However, vitamin D insufficiency could not determine hospitalisation (OR=1.42; 95% CI 0.27 to 7.34; p=0.68 and OR=1.65; 95% CI 0.07 to 41.7; p=0.76 when adjusted by baseline covariates). CONCLUSIONS The vitamin D insufficiency of septic patients in our ED was high and had a significant negative association with sepsis severity. However, vitamin D insufficiency status cannot predict the hospitalisation of septic patients who were admitted to the ED. Further research is needed to investigate the role of vitamin D supplementation in the ED in affecting sepsis severity. TRIAL REGISTRATION NUMBER TCTR20151127001.

Abstract
OBJECTIVE To develop and validate a mechanical power (MP)-oriented prediction model of weaning failure in mechanically ventilated patients. DESIGN A retrospective cohort study. SETTING Data were collected from the large US Medical Information Mart for Intensive Care-IV (MIMIC-IV) V.1.0, which integrates comprehensive clinical data from 76 540 intensive care unit (ICU) admissions from 2008 to 2019. PARTICIPANTS A total of 3695 patients with invasive mechanical ventilation for more than 24 hours and weaned with T-tube ventilation strategies were enrolled from the MIMIC-IV database. PRIMARY AND SECONDARY OUTCOME Weaning failure. RESULTS All eligible patients were randomised into development cohorts (n=2586, 70%) and validation cohorts (n=1109, 30%). Multivariate logistic regression analysis of the development cohort showed that positive end-expiratory pressure, dynamic lung compliance, MP, inspired oxygen concentration, length of ICU stay and invasive mechanical ventilation duration were independent predictors of weaning failure. Calibration curves showed good correlation between predicted and observed outcomes. The prediction model showed accurate discrimination in the development and validation cohorts, with area under the receiver operating characteristic curve values of 0.828 (95% CI: 0.812 to 0.844) and 0.833 (95% CI: 0.809 to 0.857), respectively. Decision curve analysis indicated that the predictive model was clinically beneficial. CONCLUSION The MP-oriented model of weaning failure accurately predicts the risk of weaning failure in mechanical ventilation patients and provides valuable information for clinicians making decisions on weaning.

Abstract
INTRODUCTION Anaemia is highly prevalent in critical illness and is associated with impaired outcomes during and after hospitalisation. However, the impact of interventions designed to attenuate or treat anaemia during critical illness on post-hospitalisation haemoglobin recovery and functional outcomes is unclear. METHODS AND ANALYSIS The Practical Anemia Bundle for Sustained Blood Recovery (PABST-BR) clinical trial is a pragmatic, open-label, parallel group, single-centre, randomised clinical trial assessing the impact of a multifaceted anaemia prevention and treatment strategy versus standard care for improvement of haemoglobin concentrations and functional outcomes after critical illness. The intervention, which will be delivered early in critical illness for those with moderate-to-severe anaemia (ie, haemoglobin <100 g/L), includes three components: (1) optimised phlebotomy, (2) clinical decision support and (3) pharmacological anaemia treatment directed at the underlying aetiology of anaemia. In-person assessments will occur at 1 and 3 months post-hospitalisation for laboratory evaluations and multidimensional functional outcome assessments. The primary outcome is differences in haemoglobin concentrations between groups, with secondary endpoints of anaemia-related fatigue, physical function, cognition, mental health, quality of life, phlebotomy volumes and frequency, transfusions, readmissions and mortality through 1-year post-hospitalisation. ETHICS AND DISSEMINATION The study has been approved by the Institutional Review Board of the Mayo Clinic in Minnesota, USA. A Data Safety Monitoring Plan has been created in accordance with the policies of the Institutional Review Board and the study funder, the National Heart, Lung and Blood Institute of the National Institutes of Health (NIH). The study will comply with NIH data sharing and dissemination policies. Results will be presented at national and international meetings and published in peer-reviewed journals. Designing and testing strategies to optimise haemoglobin recovery and improve functional outcomes after critical illness remain important research gaps. The PABST-BR trial will inform the development of a larger multicentre clinical trial. TRIAL REGISTRATION NUMBER NCT05167734.
