Development of a risk predication model for critical care needs in patients with intracerebral hemorrhage: a retrospective cohort.

It is very important to provide the correct nursing care for patients with intracerebral hemorrhage (ICH), but the level of critical care needs in patients with intracerebral hemorrhage is not clear. The purpose of this study is to establish a risk model based on the epidemiological and clinical characteristics of ICH patients, to help identify the critical care needs of ICH patients. The clinical data of ICH patients from January 2018 to September 2023 were analyzed retrospectively. The full cohort was used to derive the clinical prediction model and the model was internally validated with bootstrapping. Discrimination and calibration were assessed using the area under curve (AUC) and the Hosmer-Lemeshow tests, respectively. 611 patients with ICH were included for model development. 61.21% (374/611) ICH patients had received critical care interventions. The influencing factors included in the model were Glasgow Coma Scale (GCS) score, intraventricular hemorrhage, past blood pressure control, systolic blood pressure on admission and bleeding volume. The model's goodness-of-fit was evaluated, which yielded a high area under the curve (AUC) value of 0.943, indicating a good fit. For the purpose of model validation, a cohort of 260 patients with ICH was utilized. The model demonstrated a Youden's index of 0.750, with a sensitivity of 90.56% and a specificity of 78.22%. GCS, systolic blood pressure, intraventricular hemorrhage, bleeding volume and past blood pressure control are the main factors affecting the critical care needs of patients with ICH. This study has deduced a clinical predictive model with good discrimination and calibration to provide scoring criteria for clinical health care providers to accurately evaluate and identify the critical care needs of ICH patients, to improve the rational integration and allocation of medical resources.

Trauma Scores Show Limited Utility for Predicting In-Flight Deterioration in Air Medical Patients

ObjectiveThe aim of this study was to determine the utility of the Triage Revised Trauma Score (TRTS), Glasgow Coma Scale/Age/systolic Pressure (GAP) score, and Shock Index (SI) in predicting in-flight hypotension and the need for critical care interventions in air medical trauma patients. MethodsA retrospective review of 3,582 air medical trauma cases from a 3-year period in Queensland was conducted. An initial TRTS, GAP score, and SI were calculated for each patient, and the lowest in-flight mean arterial pressure and systolic blood pressure were determined. The institution of in-flight critical care interventions was also recorded, including fluid resuscitation, vasopressors, and surgical procedures. The utility of the TRTS, GAP score, and SI for predicting in-flight hypotension was then examined using receiver operating characteristic curves. ResultsAll 3 approaches showed minor predictive value, with the GAP score performing slightly better than TRTS and SI for predicting in-flight interventions. The GAP score had a receiver operating characteristic area under the curve of 0.76 compared with 0.74 for the TRTS and SI. ConclusionNo score demonstrated sufficient predictive ability for deterioration in transit to be used clinically.

Augmentative and Alternative Communication Interventions in Critical and Acute Care With Mechanically Ventilated and Tracheostomy Patients: A Scoping Review.

Communication with nonspeaking patients is a critical challenge of person-centered care. This scoping review aimed to map the literature on augmentative and alternative communication (AAC) interventions for nonspeaking mechanically ventilated and tracheostomy patients in critical and acute care settings. Electronic database, ancestry, and forward citation searches were conducted using eligibility criteria established a priori. Data were extracted, synthesized, and summarized according to scoping review methodology. Studies were categorized by type of intervention and summarized in terms of purpose, participants, design, quality appraisal (including validity and reliability of selected efficacy measures), and efficacy. Small-to-large treatment effect sizes indicated demonstrable impact on patient health and communication efficacy with high-tech and no-tech visual interface-based interventions and systematic nurse training interventions. Treatment effects primarily pertained to dependent variables of patient anxiety, communication satisfaction, comfort, symptom self-reporting, and nursing practice changes. There is a paucity of high-quality AAC intervention research for mechanically ventilated and tracheostomy patients in critical and acute care settings. Emergent evidence suggests that select visual interface and nurse training interventions can impact efficacy of patient-provider communication and patients' overall health. https://doi.org/10.23641/asha.26506102.

WP3.15 - National Emergency Laparotomy (NELA) deaths within 90 days: A cohort study

Abstract Aims NELA is committed to enhancing quality of care of patients undergoing emergency laparotomy. NELA care pathways include: initial clinical assessment, resuscitation, prompt diagnosis, early surgery, peri-operative care. NELA emphasizes the importance of identifying high risk patients, who are associated with significant morbidity & mortality. Aim of study is to review the NELA 90-day deaths. Methods Cohort study of NELA deaths within 90 days, from Jan'2014 to Jan'2024 at single centre. Descriptive demography, outcomes were evaluated. NELA survivors beyond 90 days were controls. Results 90 Day (n = 113) Others (n = 751) Mann Whitney U (p value) Age(yrs) 74.3 66.6 < 0.0001 Sex(M:F) 58 : 55 334 : 417 NS ASA 3 2 < 0.0001 BMI(kg/m2) 25.1 25.7 NS Lap(n) 16 218 Ns Open(n) 97 533 < 0.01 Op time(mins) 120.2 119.1 NS LOS(days) 17 12 NS ITU/HDU 70 318 < 0.001 ITU stay(day) 3 2 < 0.05 Lactate(mmol/L) 3.0 1.9 0.0002 WCC(x109/L) 13.2 12.3 NS CRP(mg/L) 93.6 68.8 < 0.0001 Physiological score 28.2 21.6 < 0.0001 Operative severity score 20.0 16.4 < 0.0001 Pre possum score 29.4 11.9 < 0.0001 PP mortality score 23.4 6.1 < 0.0001 PP morbidity score 82.9 63.5 < 0.0001 Survival Rate (%) 1styear 81.4 5thyear 63.0 10thyear 50.7 Conclusion 90-day NELA mortality rate is 13.1 %. NELA deaths occurred in older, frail, multi-comorbid & higher ASA status Patient survival appears to plateau out beyond 90-days (natural deaths). NELA risk scores were greater amongst the 90-day deaths. NELA risk scores can identify high risk patients, where early collaborative senior assessment by consultant surgeons, anaesthetist and intensivists may identify and allocate appropriate surgical & critical care intervention.

Veno-venous extracorporeal membrane oxygenation-assisted treatment of severe airway stenosis due to goiter: Two case reports.

Extracorporeal membrane oxygenation (ECMO) is a critical care intervention that acts as a temporary substitute for the heart and lungs, facilitating adequate tissue perfusion and gas exchange. The 2 primary configurations, veno-arterial and veno-venous ECMO, are tailored to support either the heart and lungs or the lungs alone, respectively. The case report details patients with tumor-induced airway stenosis who encountered limitations with standard treatments, which were either insufficient or carried the risk of severe complications such as hypoxia and asphyxia. Patients were diagnosed with severe airway stenosis caused by goiter, a condition that required innovative treatment approaches to prevent complications during the management process. Veno-venous ECMO was implemented as a bridging therapy to provide vital respiratory support during the tumor resection procedure. This intervention was crucial in reducing the risks associated with airway edema or tumor rupture. With the use of veno-venous ECMO, the patients successfully underwent tumor resection. They were subsequently weaned off the ECMO support, and after a course of treatment, they were discharged in good condition. The case demonstrates the efficacy of veno-venous ECMO as a bridging therapy for managing severe airway stenosis caused by goiter. Its use facilitated the successful resection of tumors and led to positive patient outcomes, highlighting its potential as a valuable treatment option in similar scenarios.

Optimising Clinical Epidemiology in Disease Outbreaks: Analysis of ISARIC-WHO COVID-19 Case Report Form Utilisation.

Standardised forms for capturing clinical data promote consistency in data collection and analysis across research sites, enabling faster, higher-quality evidence generation. ISARIC and the World Health Organization have developed case report forms (CRFs) for the clinical characterisation of several infectious disease outbreaks. To improve the design and quality of future forms, we analysed the inclusion and completion rates of the 243 fields on the ISARIC-WHO COVID-19 CRF. Data from 42 diverse collaborations, covering 1886 hospitals and 950,064 patients, were analysed. A mean of 129.6 fields (53%) were included in the adapted CRFs implemented across the sites. Consistent patterns of field inclusion and completion aligned with globally recognised research priorities in outbreaks of novel infectious diseases. Outcome status was the most highly included (95.2%) and completed (89.8%) field, followed by admission demographics (79.1% and 91.6%), comorbidities (77.9% and 79.0%), signs and symptoms (68.9% and 78.4%), and vitals (70.3% and 69.1%). Mean field completion was higher in severe patients (70.2%) than in all patients (61.6%). The results reveal how clinical characterisation CRFs can be streamlined to reduce data collection time, including the modularisation of CRFs, to offer a choice of data volume collection and the separation of critical care interventions. This data-driven approach to designing CRFs enhances the efficiency of data collection to inform patient care and public health response.

Weaning-associated interventions for ventilated intensive care patients: A scoping review.

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. To provide an overview of interventions associated with ventilator weaning. 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. 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). 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). 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.

Simulation as Proof of Concept to Assess the Feasibility and Address Uncertainties Regarding Cardiopulmonary Resuscitation in an Adolescent Patient With Viral Hemorrhagic Fever.

While general management guidelines exist for patients with viral hemorrhagic fevers (VHF), uncertainty surrounds the extent to which critical care interventions should be provided. There has been significant concern in providing cardiopulmonary resuscitation (CPR) to a patient with VHF due to concerns regarding CPR efficiency and the safety of the healthcare team. However, data on CPR feasibility, efficiency, and latent safety threats (LSTs) to the healthcare team in patients with VHF needing CPR are lacking. Our team proactively studied this in the simulation environment as the first step to guiding evidence-based and ethically informed decisions about CPR for these patients. We studied CPR metrics, times to critical interventions, and LSTs using systems-focused debriefing in an adolescent patient with VHF who had pulseless electrical activity. This exercise included 3 members inside the patient room in full PPE and special pathogens team members in modified PPE outside the room. We found that CPR is feasible in full PPE. The chest compression fraction was 72%, with an average manual rate of 129 compressions per minute and an average manual depth of 2.1 inches. We identified multiple LSTs in the debriefing and video analysis. This simulation study showed that CPR in a patient with VHF is possible in full PPE with a minimum of 3 team members. However, we identified physical and psychological LSTs with the systems-focused debriefing. Therefore, refining roles and responsibilities would be necessary to improve the safety of the healthcare team and improve the quality of CPR.

Health Disparities in Cardiac Critical Care: Understanding Inequities, Barriers, and Pathways Toward Equitable Access and Enhanced Outcomes.

Health disparities in cardiac critical care continue to pose significant challenges in achieving equitable access and outcomes for diverse populations. This literature review examines the disparities in access to and outcomes of cardiac critical care interventions across different populations, identifies barriers contributing to these disparities, and explores strategies to address them. A literature review was conducted by searching electronic databases for relevant articles published between January 2000 and May 2023. Studies focusing on health disparities in cardiac critical care, access to interventions, outcomes, and equity were included. Data were extracted and synthesized using a narrative approach. Disparities in access to cardiac critical care interventions were identified, including socioeconomic factors, lack of health insurance, geographic barriers, racial and ethnic disparities, language and cultural barriers, limited health literacy, and lack of awareness and education. These barriers led to delayed diagnoses, suboptimal utilization of interventions, and limited access to specialized cardiac care. Disparities in outcomes were also observed, with certain populations experiencing worse clinical outcomes and higher morbidity and mortality rates. This review emphasizes the existence of disparities in cardiac critical care and emphasizes the necessity for interventions to address these disparities. Specific strategies should concentrate on enhancing healthcare access, diminishing financial obstacles, expanding health insurance coverage, fostering patient-centered approaches, and harnessing telemedicine and technology. Collaborative efforts among policymakers, healthcare providers, researchers, and patient advocates are vital to advocate for policy changes and implement evidence-based interventions that foster equitable care. Future research should prioritize longitudinal studies, implementation science, patient engagement, global perspectives, and rigorous evaluation of intervention strategies to advance our knowledge and guide endeavors in reducing health disparities in cardiac critical care.

Long-term renal function after burn-related acute kidney injury with continuous renal replacement therapy

Acute kidney injury (AKI) is a common complication of severe burn injury and is associated with significant morbidity and mortality. Continuous Renal Replacement Therapy (CRRT) is the preferred treatment for stage 3 AKI due to severe burn. This retrospective cohort study at a single institution aimed to examine the long-term renal outcomes after discharge of burn survivors who underwent CRRT during their ICU stay between 2012–2021 due to burn-related AKI, hypothesizing a return to baseline renal function in the long term. Among the 31 patients meeting inclusion criteria, 22 survived their burn injuries, resulting in a 29 % mortality rate. No significant disparities were observed in demographics, comorbidities, burn characteristics, or critical care interventions between survivors and non-survivors. Serum creatinine and eGFR values normalized for 91 % of patients at discharge. Impressively, 91 % of survivors demonstrated a return to baseline renal function during long-term (>3 years) follow-up. Furthermore, only 18 % underwent dialysis after discharge, primarily within the first year. Cumulative mortality rates were 18.2 %, 22.7 %, and 31.8 % at 1, 3, and > 3 years after discharge, respectively. Causes of death were primarily non-renal. These results suggest that burn-related AKI with CRRT results in lower rates of conversion to ongoing renal dysfunction compared to general ICU cohorts. Despite limitations, this study contributes vital insights into the underexplored issue of long-term outcomes after dicharge in this patient population.

Inpatient burden and clinical outcomes of cytokine release syndrome in patients with cancer: A National Inpatient Sample study.

11067 Background: Cytokine release syndrome (CRS) is a potentially life-threatening complication commonly seen in patients receiving chimeric antigen receptor (CAR)-T cell therapy, allogeneic stem cell transplant, or immunotherapies. This study aims to evaluate the inpatient burden outcomes of CRS leading to hospitalization in patients diagnosed with cancer. Methods: Hospitalizations for cytokine release syndrome (CRS) were identified using ICD-10 coding from the 2020 National Inpatient Sample (NIS), the largest all-payer inpatient database in the US. Only CRS patients with a co-diagnosis of cancer (identified using the Clinical Classification Software (CCS) coding) were included in this study. The underlying severity of illness index was used to verify CRS grading. Sampling weights were applied to generate nationally representative estimates. Results: In 2020, there were 4,765 hospitalizations coded with CRS. 27.2% of these admissions had a co-diagnosis of cancer (n=1,295) and were included in the final analysis. The top co-diagnoses in the patients with CRS without cancer were COVID-19 infection and sepsis. Hematologic malignancies had the highest incidence amongst cancer types (75.7%), the distribution was as follows: 29.6% with diffuse large B-cell lymphoma, 19.9% with acute lymphoblastic leukemia, 12.8% with multiple myeloma, 12.2% with acute myeloid leukemia, and 7.7% with mantle cell lymphoma. The most common procedures in oncology patients hospitalized with CRS were CAR-T cell therapy (29.3%), chemotherapy (28.6%), stem cell transplant (8.5%), or Blinatumomab bispecific antibody (5.4%). 11.4% of patients with CRS received tocilizumab. Of those that received tocilizumab, 10% were CRS grade 2, 56.7% were grade 3, 33.3% were grade 4. 51.7% of tocilizumab was given in the first 48 hours of admission. A minority of CRS patients required critical care interventions: 12.0% requiring intubation, 5.8% requiring vasopressor support, and 2.7% received dialysis. Overall, 10.4% of all oncology admissions with CRS resulted in death during hospitalization (n=135). Of these deaths, 92.6% were in the extreme severity of illness and 63.0% were CRS grade 4. Those with CRS who died during hospitalization had a significantly longer length of stay (24.6 vs 13.6 days, p<0.001). The overall median hospital charges of a CRS-related admission were $531,692. Conclusions: This study represents the inpatient burden of CRS-related admissions in patients diagnosed with cancer. CRS admissions are commonly seen in patients with hematologic malignancies, those undergoing CAR-T cell or immunotherapies (bispecific antibodies). CRS poses a significant healthcare burden, with average hospital charges being greater than 0.5 million US dollars per admission. About 1 in 10 patients with CRS died during hospitalization with higher mortality likely with severe CRS grades and longer length of stay.

Ventilator-induced Lung Injury Promotes Inflammation within the Pleural Cavity.

Mechanical ventilation contributes to the morbidity and mortality of patients in intensive care, likely through the exacerbation and dissemination of inflammation. Despite the proximity of the pleural cavity to the lungs and exposure to physical forces, little attention has been paid to its potential as an inflammatory source during ventilation. Here, we investigate the pleural cavity as a novel site of inflammation during ventilator-induced lung injury. Mice were subjected to low or high tidal volume ventilation strategies for up to 3 hours. Ventilation with a high tidal volume significantly increased cytokine and total protein levels in BAL and pleural lavage fluid. In contrast, acid aspiration, explored as an alternative model of injury, only promoted intraalveolar inflammation, with no effect on the pleural space. Resident pleural macrophages demonstrated enhanced activation after injurious ventilation, including upregulated ICAM-1 and IL-1β expression, and the release of extracellular vesicles. In vivo ventilation and invitro stretch of pleural mesothelial cells promoted ATP secretion, whereas purinergic receptor inhibition substantially attenuated extracellular vesicles and cytokine levels in the pleural space. Finally, labeled protein rapidly translocated from the pleural cavity into the circulation during high tidal volume ventilation, to a significantly greater extent than that of protein translocation from the alveolar space. Overall, we conclude that injurious ventilation induces pleural cavity inflammation mediated through purinergic pathway signaling and likely enhances the dissemination of mediators into the vasculature. This previously unidentified consequence of mechanical ventilation potentially implicates the pleural space as a focus of research and novel avenue for intervention in critical care.

Emergency critical care: closing the gap between onset of critical illness and intensive care unit admission.

Critical illness is an exquisitely time-sensitive condition and follows adisease continuum, which always starts before admission to the intensive care unit (ICU), in the majority of cases even before hospital admission. Reflecting the common practice in many healthcare systems that critical care is mainly provided in the confined areas of an ICU, any delay in ICU admission of critically ill patients is associated with increased morbidity and mortality. However, if appropriate critical care interventions are provided before ICU admission, this association is not observed. Emergency critical care refers to critical care provided outside of the ICU. It encompasses the delivery of critical care interventions to and monitoring of patients at the place and time closest to the onset of critical illness as well as during transfer to the ICU. Thus, emergency critical care covers the most time-sensitive phase of critical illness and constitutes one missing link in the chain of survival of the critically ill patient. Emergency critical care is delivered whenever and wherever critical illness occurs such as in the pre-hospital setting, before and during inter-hospital transfers of critically ill patients, in the emergency department, in the operating theatres, and on hospital wards. By closing the management gap between onset of critical illness and ICU admission, emergency critical care improves patient safety and can avoid early deaths, reverse mild-to-moderate critical illness, avoid ICU admission, attenuate the severity of organ dysfunction, shorten ICU length of stay, and reduce short- and long-term mortality of critically ill patients. Future research is needed to identify effective models to implement emergency critical care systems in different healthcare systems.

Expert consensus on the application of critical care ultrasonography in invasive procedures

The evolution of critical care medicine is inextricably linked to the development of critical care procedures. These procedures not only facilitate diagnosis and treatment of critically ill patients, but also provide valuable insights into disease pathophysiology. While critical care interventions offer undeniable benefits, the potential for iatrogenic complications necessitates careful consideration. The recent surge in critical care ultrasound (US) utilization is a testament to its unique advantages: non-invasiveness, real-time bedside availability, direct visualization of internal structures, elimination of ionizing radiation exposure, repeatability, and relative ease of learning. Recognizing the need to optimize procedures and minimize complications, critical care utrasound study group of Beijing critical care ultrasound research assocition convened a panel of critical care experts to generate this consensus statement. This document serves as a guide for healthcare providers, aiming to ensure patient safety and best practices in critical care.

Incidence of Weaning Failure in Obese Patients in Intensive Care Unit.

Background The escalating prevalence of obesity worldwide presents unique challenges in critical care management, especially in the context of mechanical ventilation and weaning processes in intensive care units (ICUs). The present study aimed to determine the incidence of weaning failure in obese patients in an ICU. Methods A prospective observational study was carried out to gather data on patients in the ICU of Shifa International Hospital located in Islamabad, Pakistan. The target population consisted of adult patients who were both male and female, ages 18 years and above. These individuals required intubation procedures as well as mechanical ventilation during their hospitalization. The researchers followed these patients prospectively and observed their medical conditions closely to gather data about how obesity might impact critical care interventions and outcomes. Results The sample size was 288 bearing a median age of 61.0 with an interquartile range of 19 years. Older age manifested a significantly higher frequency of failed extubation (p=0.065). Higher body mass index (BMI) was significantly associated with failed extubation among the study population. It was found that a higher significant difference was associated with BMI > 30 kg/m2 (obese) in failed and successful extubation. One-half of the patients with failed extubation and only 16 (5.9%) patients with successful extubation had end-stage renal disease (p<0.001). It was found that patients who underwent failed extubation had notably increased ICU mortality (p=0.108), 28-day mortality (p=0.067), as well as mean ICU (p<0.001) and hospital stay (p=0.007). Conclusion Our study revealed some insightful correlations between obesity, age, comorbidities, length of hospitalization, ICU stay, and mortality rate in terms of weaning failure among the study population.

Characteristics and critical care interventions in drowning patients treated by the Danish Air Ambulance from 2016 to 2021: a nationwide registry-based study with 30-day follow-up

BackgroundImproving oxygenation and ventilation in drowning patients early in the field is critical and may be lifesaving. The critical care interventions performed by physicians in drowning management are poorly described. The aim was to describe patient characteristics and critical care interventions with 30-day mortality as the primary outcome in drowning patients treated by the Danish Air Ambulance.MethodsThis retrospective cohort study with 30-day follow-up identified drowning patients treated by the Danish Air Ambulance from January 1, 2016, through December 31, 2021. Drowning patients were identified using a text-search algorithm (Danish Drowning Formula) followed by manual review and validation. Operational and medical data were extracted from the Danish Air Ambulance database. Descriptive analyses were performed comparing non-fatal and fatal drowning incidents with 30-day mortality as the primary outcome.ResultsOf 16,841 dispatches resulting in a patient encounter in the six years, the Danish Drowning Formula identified 138 potential drowning patients. After manual validation, 98 drowning patients were included in the analyses, and 82 completed 30-day follow-up. The prehospital and 30-day mortality rates were 33% and 67%, respectively. The National Advisory Committee for Aeronautics severity scores from 4 to 7, indicating a critical emergency, were observed in 90% of the total population. They were significantly higher in the fatal versus non-fatal group (p < 0.01). At least one critical care intervention was performed in 68% of all drowning patients, with endotracheal intubation (60%), use of an automated chest compression device (39%), and intraosseous cannulation (38%) as the most frequently performed interventions. More interventions were generally performed in the fatal group (p = 0.01), including intraosseous cannulation and automated chest compressions.ConclusionsThe Danish Air Ambulance rarely treated drowning patients, but those treated were severely ill, with a 30-day mortality rate of 67% and frequently required critical care interventions. The most frequent interventions were endotracheal intubation, automated chest compressions, and intraosseous cannulation.

Managing End of Life Care for the Critically Ill: A Novel Program to Deliver Bedside Critical Care Without Transfer to the Intensive Care Unit

Background: Navigating medical care at the end of life can be a challenging experience for patients. There are also significant resource burdens, including intensive care unit (ICU) admissions, accompanying terminal illness. For actively dying patients, developing a care plan based on patient goals and delivering care at the bedside can enhance patient well-being, avoid inappropriate transfers or interventions, and improve resource management. Methods: The Rapid Response Team (RRT) is an around the clock intensivist service that responds to all acutely decompensating patients in our hospital. Through the Appropriate Care Escalation (ACE) program, the RRT intensivist identifies amongst decompensating patients, terminally ill individuals for whom prognosis is extremely poor irrespective of available interventions. These patients receive discussions about goals of care, code status, and management options. They receive care on a dedicated stepdown unit without escalation to the ICU. If aligned with patient goals, care plans incorporate critical care interventions including ventilator and vasopressor therapy. Results: Over 5 years, RRT identified 413 terminally ill patients under the ACE program to continue end of life care on the stepdown unit. Following discussions of goals, 60.8% of patients requested DNR/DNI, 30.9% were full code, and 8.5% requested DNR/OK-TO-INTUBATE status. At discharge, 82.1% of ACE patients expired compared to 23% of all RRT consultations. Patients received 233 critical care procedures at bedside including intubations, central access catheters and bronchoscopy. Conclusion: The ACE program helped identify, in real time, actively dying, terminally ill patients, establish patient goals, and expand critical care services outside the ICU.

Safety and Risk in Airway Management During Bariatric Air Medical Retrieval

ObjectiveBariatric anatomy and physiology present added clinical challenges to the provision of safe critical care and patient transport. LifeFlight Retrieval Medicine provides air medical retrieval services in Queensland, Australia, and performs over 6,000 retrieval missions annually using rotary wing, fixed wing, and ground ambulance platforms. MethodsBariatric patient retrievals were identified from the LifeFlight Retrieval Medicine electronic patient database. These cases were interrogated to quantify and describe adverse events during patient transport. ResultsOver the study period from July 2019 to December 2021 11,096 patient retrievals were completed. Of these patients, 816 (7.3%) had a body weight ≥ 120 kg (range, 120-246 kg; median = 146 kg). Bariatric patients were more likely to be male (70%) and to require critical care interventions than nonbariatric patients (25.9% vs. 19.9%). There was an absolute 1.5% increase of high-interest events during patient retrieval, corresponding to a 1.9-fold increased relative risk. Five hundred eleven of 11,096 patients were intubated by the retrieval team, and 61 of these weighed ≥ 120 kg. Bariatric patients undergoing intubation were of similar age and sex, weighed significantly more, had nonsignificant trends toward poorer airway visualization by Cormack-Lehane laryngoscopic grade, and tended toward reduced first-attempt success compared with nonbariatric patients. Rates of airway adverse events (AAEs) were significantly increased for the bariatric group (30/61, 49.2%) compared with the nonbariatric group (135/450, 30.0%) (χ2 likelihood ratio, P = .004). Postintubation desaturation was the most common AAE and was the only criterion significantly increased when comparing bariatric (26%) versus nonbariatric (12%) patients (χ2 likelihood ratio, P = .005). Using patient weight as a continuous variable, nominal logistic regression revealed a significant effect of increasing weight on AAEs (χ2 = 12.9, P = .0003) with a threshold of 105 kg providing an optimal 88% sensitivity for predicting AAEs. The odds of AAEs were increased significantly for those weighing 105 to 119 kg versus those weighing < 105 kg (odds ratio [OR] = 3.4; 95% confidence interval [CI], 1.6-7.5) and for those weighing ≥ 120 kg versus those weighing < 105 kg (OR = 2.5; 95% CI, 1.4-4.3). There was no difference between those weighing ≥ 120 kg versus those weighing 105 to 119 kg (OR = 0.73; 95% CI, 0.3-1.8). ConclusionAir medical retrieval of bariatric patients is safe despite an increased risk of adverse events. Strategies to optimize emergency anesthesia should be used to maximize safe intubation in bariatric patients.

A Comprehensive Review of Extra Corporeal Membrane Oxygenation: The Lifeline in Critical Moments.

Extracorporeal membrane oxygenation (ECMO) has evolved into a pivotal intervention in critical care, offering a lifeline for patients facing severe respiratory or cardiac failure. This review provides a comprehensive exploration of ECMO, spanning its definition and historical background to its contemporary advancements and ongoing impact in critical care. The versatility of ECMO in addressing diverse critical conditions, careful patient selection criteria, and the nuanced management of complications are discussed. Advances in technology, including miniaturization, novel circuit designs, and the integration of remote monitoring, showcase the evolving landscape of ECMO. The review underscores the ongoing impact of ECMO in improving survival rates, enhancing mobility, and enabling remote expertise. As a symbol of hope and innovation, ECMO's lifesaving potential is evident in its ability to navigate the complexities of critical care and redefine the boundaries of life support interventions.

The trajectory of very old critically ill patients.

The demographic shift, together with financial constraint, justify a re-evaluation of the trajectory of care of very old critically ill patients (VIP), defined as older than 80 years. We must avoid over- as well as under-utilisation of critical care interventions in this patient group and ensure the inclusion of health care professionals, the patient and their caregivers in the decision process. This new integrative approach mobilises expertise at each step of the process beginning prior to intensive care unit (ICU) admission and extending to long-term follow-up. In this review, several international experts have contributed to provide recommendations that can be universally applied. Our aim is to define a minimum core dataset of information to be shared and discussed prior to ICU admission and to facilitate the shared-decision-making process with the patient and their caregivers, throughout the patient journey. Documentation of uncertainty may contribute to a tailored level of care and ultimately to discussions around possible limitations of life sustaining treatments. The goal of ICU care is not only to avoid death, but more importantly to maintain an acceptable quality of life and functional autonomy after hospital discharge. Societal consideration is important to highlight, together with alternatives to ICU admission. We discuss challenges for the future and potential areas of research. In summary, this review provides a state-of-the-art current overview and aims to outline future directions to address the challenges in the treatment of VIP.
