Palliative Care in the Intensive Care Unit: The Standard of Care.

Intensive care unit-based palliative care has evolved over the past 30 years due to the efforts of clinicians, researchers, and advocates for patient-centered care. Although all critically ill patients inherently have palliative care needs, the path was not linear but rather filled with the challenges of blending the intensive care unit goals of aggressive treatment and cure with the palliative care goals of symptom management and quality of life. Today, palliative care is considered an essential component of high-quality critical care and a core competency of all critical care nurses, advanced practice nurses, and other intensive care unit clinicians. This article provides an overview of the current state of intensive care unit-based palliative care, examines how the barriers to such care have shifted, reviews primary and specialist palliative care, addresses the impact of COVID-19, and presents resources to help nurses and intensive care unit teams achieve optimal outcomes.

Selection of knowledge translation strategies to implement best practices on nonpharmacological prevention of delirium in intensive care unit / Sélection de stratégies de transfert des connaissances visant à implanter les pratiques recommandées de prévention non pharmacologiques du délirium en soins intensifs.

Background: Delirium prevention in the ICU should focus on a non-pharmacological approach. However, these recommendations are not always applied by care providers. Objective: To select knowledge translation strategies to facilitate the implementation of non-pharmacological best practices to prevent delirium in the ICU. Method: A consensus study was conducted. Barriers and facilitators to the implementation of nonpharmacological methods, and knowledge translation strategies, were identified in two nominal groups. A context assessment was also carried out. Nine professionals and one patient-partner participated. Results: The barriers and facilitators on which consensus was reached were most frequently related to environmental context and resources, intention, and knowledge. The areas of organizational context with the highest levels of agreement were interpersonal relations, culture and leadership. Consequently, knowledge translation strategies were selected to facilitate practices, as well as to modify the environment and improve knowledge. Conclusion: A structured method was used during this study to guide the selection of knowledge translation strategies. The application of these strategies could potentially improve clinical practice in intensive care.

Introduction: La prévention du délirium aux soins intensifs devrait être axée sur les méthodes non pharmacologiques. Toutefois, ce type de recommandation n'est pas toujours appliqué. Objectif: Sélectionner des stratégies de transfert des connaissances afin de faciliter l'implantation des pratiques non pharmacologiques pouvant prévenir le délirium en soins intensifs. Méthode: Une étude de consensus a été réalisée autour de deux thèmes. Deux groupes nominaux ont été constitués pour identifier les barrières et les facilitateurs à l'implantation des méthodes et les stratégies de transfert des connaissances. Une évaluation du contexte a aussi été réalisée. Neuf professionnels et une patiente-partenaire ont participé. Résultats: Les barrières et les facilitateurs ayant fait l'objet d'un consensus étaient plus fréquemment reliés au contexte environnemental et aux ressources, à l'intention et aux connaissances. Les domaines du contexte organisationnel qui ont obtenu le plus haut niveau d'accord sont les relations interpersonnelles, la culture et le leadership. Conséquemment, des stratégies de transfert des connaissances pour faciliter les pratiques, modifier l'environnement et améliorer les connaissances ont été sélectionnées. Conclusion: Une méthode structurée a été utilisée afin de guider la sélection de stratégies de transfert des connaissances. L'application de ces stratégies pourrait potentiellement améliorer la pratique clinique en soins intensifs.

Ischemic Stroke in the Cardiac Surgery Intensive Care Unit: A Quality Improvement Study.

OBJECTIVE: To investigate the frequency of stroke and code stroke activation and the factors influencing code stroke management in postoperative cardiac surgical patients. DESIGN: A retrospective quality improvement study was conducted between January 1, 2016, and December 31, 2021. SETTING: The Cardiac Surgery Recovery Unit (CSRU) at London Health Sciences Centre in London, Ontario, Canada. PARTICIPANTS: Postcardiac surgery patients aged 18 years or older who developed ischemic stroke during their admission to the CSRU. INTERVENTIONS: No specific interventions were administered as part of this study. Code stroke activation mobilizes a specialized team. The objectives include assessment by a physician within 10 minutes, obtaining neuroimaging and interpretation within 45 minutes, and beginning treatment within 60 minutes. MEASUREMENTS AND MAIN RESULTS: The incidence rate of stroke in the CSRU was 1.3%, and 34% of these patients had code stroke activated. The time since the last known well status was 11 ± 8 hours. The most common reasons for not activating code stroke were not meeting both timing and clinical criteria. The average time for computed tomography (CT) scan was 36 ± 22 minutes. Among patients who had code stroke activated, 24% had large- vessel occlusion (LVO), and 67% of those with LVO had an established stroke on their initial CT. CONCLUSION: Code stroke was activated in only one-third of patients who experienced a stroke following cardiac surgery. Additionally, out of those who had code stroke activated, only one-fourth were diagnosed with LVO. Among those with LVO, two-thirds were found to have a well-established stroke on noncontrast CT scans and were deemed ineligible for intervention.

Utilisation of palliative/ end-of-life care practice recommendations in the burn intensive care unit of a Ghanaian tertiary healthcare facility: An observational study.

BACKGROUND: The need to integrate palliative/end-of-life care across healthcare systems is critical considering the increasing prevalence of health-related suffering. In burn care, however, a general lack of practice recommendations persists. Our burn unit developed practice recommendations to be implemented and this study aimed to examine the components of the practice recommendations that were utilised and aspects that were not to guide further training and collaborative efforts. METHODS: We employed a prospective clinical observation approach and chart review to ascertain the utilisation of the recommendations over a 3-year period for all burn patients. We formulated a set of trigger parametres based on existing literature and burn care staff consultation in our unit. Additionally, a checklist based on the practice recommendations was created to record the observations and chart review findings. All records were entered into a secure form on Google Forms following which we employed descriptive statistics in the form of counts and percentages to analyse the data. RESULTS: Of the 170 burn patients admitted, 66 (39%) persons died. Although several aspects of each practice recommendation were observed, post-bereavement support and collaboration across teams are still limited. Additionally, though the practice recommendations were comprehensive to support holistic care, a preponderance of delivering physical care was noted. The components of the practice recommendations that were not utilised include undertaking comprehensive assessment to identify and resolve patient needs (such as spiritual and psychosocial needs), supporting family members across the injury trajectory, involvement of a palliative care team member, and post-bereavement support for family members, and burn care staff. The components that were not utilised could have undoubtedly helped to achieve a comprehensive approach to care with greater family and palliative care input. CONCLUSION: We find a great need to equip burn care staff with general palliative care skills. Also, ongoing collaboration/ partnership between the burn care and palliative care teams need to be strengthened. Active family engagement, identifying, and resolving other patient needs beyond the physical aspect also needs further attention to ensure a comprehensive approach to end of life care in the burn unit.

Assessing quality of critical care during an ongoing health emergency-a novel approach to evaluate quality of care at Lebanese public ICUs during COVID-19.

BACKGROUND: Quality of care has been systematically monitored in hospitals in high-income countries to ensure adequate care. However, in low- and middle-income countries, quality indicators are not readily measured. The primary aim of this study was to assess to what extent it was feasible to monitor the quality of intensive care in an ongoing health emergency, and the secondary aim was to assess a quality of care intervention (twinning project) focused on Intensive Care Unit (ICU) quality of care in public hospitals in Lebanon. METHODS: We conducted a retrospective cohort study nested within an intervention implemented by the World Health Organization (WHO) together with partners. To assess the quality of care throughout the project, a monitoring system framed in the Donabedian model and included structure, process, and outcome indicators was developed and implemented. Data collection consisted of a checklist performed by external healthcare workers (HCWs) as well as collection of data from all admitted patients performed by each unit. The association between the number of activities within the interventional project and ICU mortality was evaluated. RESULTS: A total of 1679 patients were admitted to five COVID-19 ICUs during the study period. The project was conducted fully across four out of five hospitals. In these hospitals, a significant reduction in ICU mortality was found (OR: 0.83, P < 0.05, CI: 0.72-0.96). CONCLUSION: We present a feasible way to assess quality of care in ICUs and how it can be used in assessing a quality improvement project during ongoing crises in resource-limited settings. By implementing a quality of care intervention in Lebanon's public hospitals, we have shown that such initiatives might contribute to improvement of ICU care. The observed association between increased numbers of project activities and reduced ICU mortality underscores the potential of quality assurance interventions to improve outcomes for critically ill patients in resource-limited settings. Future research is needed to expand this model to be applicable in similar settings.

Impacto de la implementación de la estrategia multimodal de la OMS para mejorar la higiene de manos en una Unidad de Cuidados Intensivos / Impact on implementation of multimodal of World Health Organization strategies to improve hand hygiene in an Intensive Care Unit

INTRODUCCIÓN: La higiene de manos (HM) es la principal medida para disminuir las IAAS, las que en las Unidades de Cuidados Intensivos (UCI) presentan una alta prevalencia. En Chile no existe información sobre el impacto de la estrategia multimodal de la OMS para la HM en adultos. El objetivo fue evaluar el impacto de la implementación de la estrategia en una UPC. METODOLOGÍA: Estudio longitudinal con evaluación pre y post-intervención, entre los años 2018 y 2021, en la UCI del Hospital del Trabajador (HT), Santiago, Chile. La implementación se evaluó con pautas de cumplimiento de HM, consumo de jabón y productos en base alcohólica (PBA). El impacto se midió con las tasas de neumonía asociada a ventilación mecánica (NAVM), infecciones del torrente sanguíneo asociadas a CVC (ITS- CVC) y del tracto urinario por CUP (ITU-CUP), y la incidencia anual de dermatitis. RESULTADOS: El cumplimiento de pautas aumentó de 91 a 96% (p < 0,05). El consumo total de productos para la HM aumentó de 0,17 a 0,31 L/día/cama y de PBA en 10%. Las tasas de IAAS pre y post-intervención fueron para NAVM de 10,3 y 8,4; ITS-CVC de 0,8 y 1,5 e ITU-CUP de 4,2 y 5,3 por 1.000 días de exposición. La incidencia anual de dermatitis disminuyó en 30% (p < 0,05). CONCLUSIONES: La implementación de la estrategia multimodal se asoció a una disminución de las tasas de NAVM y de dermatitis en la UCI del HT.

INTRODUCTION: Hand hygiene is the main measure to decrease infections related to healthcare and the Intensive Care Unit has a high prevalence. In Chile there aren't reports about the impact of the World Health Organization multimodal hand hygiene improvement strategy. AIM: To assess the implementation impact of this strategy at the ICU. METHODOLOGY: Longitudinal study with pre- and postintervention evaluation during the years 2018-2021 at ICU. The implementation was assessed against hand hygiene compliance guidelines, soap consumption and alcohol-based products. The impact was evaluated with the rates of ventilator-associated pneumonia (VAP), catheter related bloodstream infection (CRBSI) and catheter associated urinary tract infection (CAUTI) and the annual dermatitis incidence. RESULTS: The guidelines compliance increased from 91% to 96% (p < 0.05). The total product consumption increased from 0.17 to 0.31 Liters/day/bed. The use of alcohol-based products increased by 10%. HAI rates pre- and post-intervention were for VAP 10.3 and 8.4, CRBSI 0.8 and 1.5 and CAUTI 4.2 and 5.3. The annual dermatitis incidence decreased by 30.8% (p < 0.05). CONCLUSIONS: The strategy implementation benefited the decrease of VAP and the dermatitis prevention in ICU.

Are patient volume and care level in teaching hospitals variables affecting clinical outcomes in adult intensive care units?

Teixeira et al. showed that patients admitted to the intensive care unit of a teaching hospital in a non-metropolitan region needed more support, had worse prognostic indices, and had a higher nursing workload in the first 24 hours of admission. In addition, worse outcomes, including mortality, need for dialysis, pressure injury, infection, prolonged mechanical ventilation, and prolonged hospital stay, were observed in the teaching hospital. Worse outcomes were more prevalent in the teaching hospital. Understanding the importance of teaching hospitals to implement well-established care protocols is critical. OBJECTIVE: To compare the clinical outcomes of patients admitted to the intensive care unit of teaching (HI) and nonteaching (without an academic affiliation; H2) hospitals. METHODS: In this prospective cohort study, adult patients hospitalized between August 2018 and July 2019, with a minimum length of stay of 24 hours in the intensive care unit, were included. Patients with no essential information in their medical records to evaluate the study outcomes were excluded. Resuslts: Overall, 219 patients participated in this study. The clinical and demographic characteristics of patients in H1 and H2 were similar. The most prevalent clinical outcomes were death, need for dialysis, pressure injury, length of hospital stay, mechanical ventilation >48 hours, and infection, all of which were more prevalent in the teaching hospital. CONCLUSION: Worse outcomes were more prevalent in the teaching hospital. There was no difference between the institutions concerning the survival rate of patients as a function of length of hospital stay; however, a difference was observed in intensive care unit admissions.

Clinical guidelines for stroke management: chapter 3 of 8: acute medical and surgical management

The Stroke Foundation is a national charity that partners with the community to prevent, treat and beat stroke. We stand alongside stroke survivors and their families, healthcare professionals and researchers. We build community awareness and foster new thinking and innovative treatments. We support survivors on their journey to live the best possible life after stroke. We are the voice of stroke in Australia and we work to: • Raise awareness of the risk factors, signs of stroke and promote healthy lifestyles. • Improve treatment for stroke to save lives and reduce disability. • Improve life after stroke for survivors. • Encourage and facilitate stroke research. • Advocate for initiatives to prevent, treat and beat stroke. • Raise funds from the community, corporate sector and government to continue our mission. The Stroke Foundation has been developing stroke guidelines since 2002 and in 2017 released the fourth edition. In order for the Australian Government to ensure up-to-date, best-practice clinical advice is provided and maintained to healthcare professionals, the NHMRC requires clinical guidelines be kept current and relevant by reviewing and updating them at least every five years. As a result, the Stroke Foundation, in partnership with Cochrane Australia, have moved to a model of living guidelines, in which recommendations are continually reviewed and updated in response to new evidence. This approach was piloted in a three year project (July 2018 -June 2021) funded by the Australian Government via the Medical Research Future Fund. This online version of the Clinical Guidelines for Stroke Management updates and supersedes the Clinical Guidelines for Stroke Management 2017. The Clinical Guidelines have been updated in accordance with the 2011 NHMRC Standard for clinical practice guidelines and therefore recommendations are based on the best evidence available. The Clinical Guidelines cover the whole continuum of stroke care, across 8 chapters. Review of the Clinical Guidelines used an internationally recognised guideline development approach, known as GRADE (Grading of Recommendations Assessment, Development and Evaluation), and an innovative guideline development and publishing platform, known as MAGICapp (Making Grade the Irresistible Choice). GRADE ensures a systematic process is used to develop recommendations that are based on the balance of benefits and harms, patient values, and resource considerations. MAGICapp enables transparent display of this process and access to additional practical information useful for guideline recommendation implementation.

Panorama da qualidade biológica da água destinada ao tratamento dialítico em pacientes sob cuidados críticos em Unidades de Terapia Intensiva / Overview of the biological quality of water intended for dialysis treatment in patients under critical care in Intensive Care Units

A incidência da lesão renal aguda caracteriza-se como evento frequente em pacientes críticos internados em Unidades de Terapia Intensiva e está associada ao aumento de mortalidade, causando grande impacto à Saúde Pública. As intercorrências clínicas são minimizadas com intervenções dialíticas, acarretando a exposição do paciente a volumes expressivos de água tratada durante a terapia renal em leito. As análises microbiológicas e de determinação de endotoxinas bacterianas em amostras de água tratada e em soluções de dialisato foram executadas em dois hospitais públicos do município de São Paulo, seguindo metodologias analíticas preconizadas em compêndios oficiais. A avaliação demonstrou que a porcentagem de resultados satisfatórios no período de 2010 a 2022 variou entre 35,2 a 100% e de 40 a 100% para as unidades hospitalares I e II para a água tratada, respectivamente; e, 100% para as soluções de dialisato para a unidade hospitalar I. A eficácia de ações delineadas pelas equipes técnicas das unidades hospitalares, na adequação da água destinada à terapia dialítica, aponta para a importância em estimular outras instituições hospitalares na padronização e implantação de melhoria contínua de seus sistemas de tratamento de água para uso em procedimento dialítico, prevenindo riscos adicionais aos pacientes expostos à terapia renal.

The incidence of acute kidney is high among critically ill patients admitted to Intensive Care Units and is associated with increased mortality, having a major impact on public health. Clinical complications are minimized with dialysis interventions, which expose patients to significant volumes of treated water during in-bed renal therapy. Microbiological analyzes and determination of bacterial endotoxins were performed on treated water samples and dialysate solutions in two public hospitals in São Paulo city, using analytical methodologies recommended in official compendia. The evaluation showed that the percentage of satisfactory results for treated water ranged from 35.2% to 100% in Hospital Unit I and from 40% to 100% in Hospital Unit II between 2010 and 2022. For dialysate solutions in Hospital Unit I, the percentage of satisfactory results was 100% during the same period. The effectiveness of actions implemented by the technical hospital teams, in adapting water for dialysis therapy, points to the importance of encouraging other hospital institutions to standardize and implement a program of continuous improvement for their water treatment systems used in dialysis procedures. This will help to prevent additional risks to patients exposed to renal therapy.

Evaluation of ICUs and weight of quality control indicators: an exploratory study based on Chinese ICU quality data from 2015 to 2020.

This study aimed to explore key quality control factors that affected the prognosis of intensive care unit (ICU) patients in Chinese mainland over six years (2015-2020). The data for this study were from 31 provincial and municipal hospitals (3425 hospital ICUs) and included 2 110 685 ICU patients, for a total of 27 607 376 ICU hospitalization days. We found that 15 initially established quality control indicators were good predictors of patient prognosis, including percentage of ICU patients out of all inpatients (%), percentage of ICU bed occupancy of total inpatient bed occupancy (%), percentage of all ICU inpatients with an APACHE II score ⩾15 (%), three-hour (surviving sepsis campaign) SSC bundle compliance (%), six-hour SSC bundle compliance (%), rate of microbe detection before antibiotics (%), percentage of drug deep venous thrombosis (DVT) prophylaxis (%), percentage of unplanned endotracheal extubations (%), percentage of patients reintubated within 48 hours (%), unplanned transfers to the ICU (%), 48-h ICU readmission rate (%), ventilator associated pneumonia (VAP) (per 1000 ventilator days), catheter related blood stream infection (CRBSI) (per 1000 catheter days), catheter-associated urinary tract infections (CAUTI) (per 1000 catheter days), in-hospital mortality (%). When exploratory factor analysis was applied, the 15 indicators were divided into 6 core elements that varied in weight regarding quality evaluation: nosocomial infection management (21.35%), compliance with the Surviving Sepsis Campaign guidelines (17.97%), ICU resources (17.46%), airway management (15.53%), prevention of deep-vein thrombosis (14.07%), and severity of patient condition (13.61%). Based on the different weights of the core elements associated with the 15 indicators, we developed an integrated quality scoring system defined as F score=21.35%xnosocomial infection management + 17.97%xcompliance with SSC guidelines + 17.46%×ICU resources + 15.53%×airway management + 14.07%×DVT prevention + 13.61%×severity of patient condition. This evidence-based quality scoring system will help in assessing the key elements of quality management and establish a foundation for further optimization of the quality control indicator system.

Result of the implementation of a quality management system based on the ISO 9001:2015 standard in a surgical intensive care unit.

INTRODUCTION: The implementation of Quality Management Systems (QMS) is one of the fundamental and future-oriented elements for the improvement of modern health systems. The objective of implementing a QMS in accordance with the requirements of the ISO 9001: 2015 Standard is to effectively carry out its activities, covering both technical and management aspects, guaranteeing the satisfaction of the needs and expectations of all its stakeholders, as well as compliance with legal and regulatory requirements. It must contemplate all those aspects that have an impact on the final quality of the product or service provided by the organization. OBJECTIVE: The main objective is to describe the process of implementing a QMS under the ISO 9001: 2015 Standard in the Surgical Intensive Care Unit of the General University Hospital of Elche and evaluate its results. METHODOLOGY: Carrying out and implementing a QMS in the Surgical Intensive Care Unit of the General University Hospital of Elche applying the points of the ISO 9001: 2015 Standard. The SGC has followed the benchmark of management by processes, identifying from its strategic core of mission, vision and values, the different processes involved and their interrelation reflected in the process map. Based on it, the necessary documents have been developed to describe the operation of the Unit both at an operational level through the key processes (admission and initial assessment of the patient, stabilization, follow-up, complementary tests, interconsultations, transfers and discharge) as well as which refers to procedures of a strategic or support type. RESULTS: The strategic lines that marked the beginning of the deployment of our QMS were defined with the drafting of 7 objectives, achieving 100% compliance. The key processes (7) that described the functioning of our organization were elaborated, as well as those of a strategic type (14) and support or support (5), complemented with 55 medical and nursing protocols. 20 monitoring indicators were analyzed: 6 organizational and planning type, and 14 clinical. 46 incidents were detected in the first year of implementation of the QMS that were analyzed by the Quality Commission, emerging 7 corrective actions. 14 improvement actions were developed after the application of the AMFE methodology for key processes, achieving an average of greater than 70% effectiveness after reassessment. From the analysis of patient and family satisfaction through SAIP case management, 41 of a total of 52 cases were acknowledgments in writing. CONCLUSIONS: Implementing a QMS in our Surgical Intensive Care Unit has made it possible to define the strategic lines of our organization, develop objectives, establish monitoring indicators, standardize the work of the Unit through procedures and protocols, increase safety at work through the use of lists of verification, initiate improvement actions to strengthen the weak points of the QMS itself, as well as know the degree of satisfaction and needs of our patients and the personnel who work in it.

Prevention of unplanned endotracheal extubation in intensive care unit: An overview of systematic reviews.

AIMS: This study was performed to identify and summarize systematic reviews focusing on the prevention of unplanned endotracheal extubation in the intensive care unit. DESIGN: Overview of systematic reviews. METHODS: This overview was conducted according to the Preferred Reporting Items for Overviews of Systematic Reviews, including the harms checklist. A literature search of PubMed, the Cochrane Library, CINAH, Embase, Web of Science, SINOMED and PROSPERO was performed from January 1, 2005-June 1, 2021. A systematic review focusing on unplanned extubation was included, resulting in an evidence summary. RESULTS: Thirteen systematic reviews were included. A summary of evidence on unplanned endotracheal extubation was developed, and the main contents were risk factors, preventive measures and prognosis. The most important nursing measures were restraint, fixation of the tracheal tube, continuous quality improvement, psychological care and use of a root cause analysis for the occurrence of unplanned endotracheal extubation. CONCLUSIONS: This overview re-evaluated risk factors and preventive measures for unplanned endotracheal extubation in the intensive care unit, resulting in a summary of evidence for preventing unplanned endotracheal extubation and providing direction for future research. TRIAL REGISTRATION DETAILS: The study was registered on the PROSPERO website.

Effectiveness of nonpharmacological interventions to prevent adverse events in the intensive care unit: A review of systematic reviews.

BACKGROUND: Different types of interventions have been assessed for the prevention of adverse events. However, determining which patient-safety practice is most effective can be challenging when there is no systematised evidence synthesis. An overview following the best methodological standards can provide the best reliable integrative evidence. OBJECTIVES: The objective of this study was to provide an overview of effectiveness nonpharmacological interventions aimed at preventing adverse events in the intensive care unit. METHODS: A review of systematic reviews (SRs) was conducted according to the Cochrane Handbook and PRISMA recommendations. PubMed, CINAHL, and Cochrane Library were searched for SRs published until March 2022. Two reviewers independently assessed the study's quality, using AMSTAR-2, and extracted data on intervention characteristics and effect on prevention of adverse events. RESULTS: Thirty-seven SRs were included, and 27 nonpharmacological interventions were identified to prevent 11 adverse events. Most of the reviews had critically low methodological quality. Among all the identified interventions, subglottic secretion drainage, semirecumbent position, and kinetic bed therapy were effective in preventing ventilator-associated pneumonia; the use of earplugs, early mobilisation, family participation, and music in reducing delirium; physical rehabilitation in improving muscle strength; use of respiratory support in preventing reintubation; the use of a computerised physician order entry system in reducing risk of medication errors; and the use of heated water humidifier was effective in reducing artificial airway occlusion. CONCLUSIONS: Some nonpharmacological interventions reduced adverse events in the intensive care setting. These findings should be interpreted carefully due to the low methodological quality. SRs on preventing adverse events in the intensive care unit should adhere to quality assessment tools so that best evidence can be used in decision-making.

Development and validation of a deep learning model to predict the survival of patients in ICU.

BACKGROUND: Patients in the intensive care unit (ICU) are often in critical condition and have a high mortality rate. Accurately predicting the survival probability of ICU patients is beneficial to timely care and prioritizing medical resources to improve the overall patient population survival. Models developed by deep learning (DL) algorithms show good performance on many models. However, few DL algorithms have been validated in the dimension of survival time or compared with traditional algorithms. METHODS: Variables from the Early Warning Score, Sequential Organ Failure Assessment Score, Simplified Acute Physiology Score II, Acute Physiology and Chronic Health Evaluation (APACHE) II, and APACHE IV models were selected for model development. The Cox regression, random survival forest (RSF), and DL methods were used to develop prediction models for the survival probability of ICU patients. The prediction performance was independently evaluated in the MIMIC-III Clinical Database (MIMIC-III), the eICU Collaborative Research Database (eICU), and Shanghai Pulmonary Hospital Database (SPH). RESULTS: Forty variables were collected in total for model development. 83 943 participants from 3 databases were included in the study. The New-DL model accurately stratified patients into different survival probability groups with a C-index of >0.7 in the MIMIC-III, eICU, and SPH, performing better than the other models. The calibration curves of the models at 3 and 10 days indicated that the prediction performance was good. A user-friendly interface was developed to enable the model's convenience. CONCLUSIONS: Compared with traditional algorithms, DL algorithms are more accurate in predicting the survival probability during ICU hospitalization. This novel model can provide reliable, individualized survival probability prediction.

Intensive Care Unit- Acquired Weakness and Hospital Functional Mobility Outcomes Following Invasive Mechanical Ventilation in Patients with COVID-19: A Single-Centre Prospective Cohort Study.

Background: Acute physical function outcomes in ICU survivors of COVID-19 pneumonia has received little attention. Critically ill patients with COVID-19 infection who require invasive mechanical ventilation may undergo greater exposure to some risk factors for ICU-acquired weakness (ICUAW). Purpose: To determine incidence and factors associated with ICUAW at ICU discharge and gait dependence at hospital discharge in mechanically ventilated patients with COVID-19 pneumonia. Methods: Single-centre, prospective cohort study conducted at a tertiary hospital in Madrid, Spain. We evaluated ICUAW with the Medical Research Council Summary Score (MRC-SS). Gait dependence was assessed with the Functional Status Score for the ICU (FSS-ICU) walking subscale. Results: During the pandemic second wave, between 27 July and 15 December, 2020, 70 patients were enrolled. ICUAW incidence was 65.7% and 31.4% at ICU discharge and hospital discharge, respectively. Gait dependence at hospital discharge was observed in 66 (54.3%) patients, including 9 (37.5%) without weakness at ICU discharge. In univariate analysis, ICUAW was associated with the use of neuromuscular blockers (crude odds ratio [OR] 9.059; p = 0.01) and duration of mechanical ventilation (OR 1.201; p = 0.001), but not with the duration of neuromuscular blockade (OR 1.145, p = 0.052). There was no difference in corticosteroid use between patients with and without weakness. Associations with gait dependence were lower MRC-SS at ICU discharge (OR 0.943; p = 0.015), older age (OR 1.126; p = 0.001), greater Charlson Comorbidity Index (OR 1.606; p = 0.011), longer duration of mechanical ventilation (OR 1.128; p = 0.001) and longer duration of neuromuscular blockade (OR 1.150; p = 0.029). Conclusions: In critically ill COVID-19 patients, the incidence of ICUAW and acute gait dependence were high. Our study identifies factors influencing both outcomes. Future studies should investigate optimal COVID-19 ARDS management and impact of dyspnea on acute functional outcomes of COVID-19 ICU survivors.

Use of dexmedetomidine for sedation in mechanically ventilated adult ICU patients: a rapid practice guideline

The aim of this Intensive Care Medicine Rapid Practice Guideline (ICM­RPG) was to formulate evidence­based guidance for the use of dexmedetomidine for sedation in invasively mechanically ventilated adults in the intensive care unit (ICU). We adhered to the methodology for trustworthy clinical practice guidelines, including use of the Grading of Recommendations Assessment, Development, and Evaluation approach to assess the certainty of evidence, and the Evidence-to-Decision framework to generate recommendations. The guideline panel comprised 28 international panelists, including content experts, ICU clinicians, methodologists, and patient representatives. Through teleconferences and web­based discussions, the panel provided input on the balance and magnitude of the desirable and undesirable effects, the certainty of evidence, patients' values and preferences, costs and resources, feasibility, acceptability, and research priorities. The ICM­RPG panel issued one weak recommendation (suggestion) based on overall moderate certainty of evidence: "In invasively mechanically ventilated adult ICU patients, we suggest using dexmedetomidine over other sedative agents, if the desirable effects including a reduction in delirium are valued over the undesirable effects including an increase in hypotension and bradycardia". This ICM-RPG provides updated evidence-based guidance on the use of dexmedetomidine for sedation in mechanically ventilated adults, and outlines uncertainties and research priorities.

Impact of MRI on decision-making in ICU patients with disorders of consciousness.

BACKGROUND: Recovery of consciousness is the most important survival factor in patients with acute brain injury and disorders of consciousness (DoC). Since most deaths in the intensive care unit (ICU) occur after withdrawal of life-support, medical decision-making is crucial for acute DoC patients. Neuroimaging informs decision-making, yet the precise effects of MRI on decision-making in the ICU are poorly understood. We investigated the impact of brain MRI on prognostication, therapeutic decisions and physician confidence in ICU patients with DoC. METHODS: In this simulated decision-making study utilizing a prospective ICU cohort, a panel of neurocritical experts first reviewed clinical information (without MRI) from 75 acute DoC patients and made decisions about diagnosis, prognosis and treatment. Following review of the MRI, the panel then decided if the initial decisions needed revision. In parallel, a blinded neuroradiologist reassessed all neuroimaging. RESULTS: MRI led to changes in clinical management of 57 (76%) of patients (Number-Needed-to-Test for any change: 1.32), including revised diagnoses (20%), levels of care (21%), diagnostic confidence (43%) and prognostications (33%). Decisions were revised more often with stroke than with other brain injuries (p = 0.02). However, although MRI revealed additional pathology in 81%, this did not predict revised clinical decision-making (p-values ≥0.08). CONCLUSION: MRI results changed decision-making in 3 of 4 ICU patients, but radiological findings were not predictive of clinical decision-making. This highlights the need to better understand the effects of neuroimaging on management decisions. How MRI influences decision-making in the ICU is an important avenue for research to improve acute DoC management.

Utilizing triage rates to improve ICU admission guidelines of elderly rib fracture patients.

BACKGROUND: Elderly rib fracture patients are generally admitted to an ICU which may result in overutilization of scarce resources. We hypothesized that this practice results in significant overtriage. METHODS: Retrospective study of patients over age 70 with acute rib fracture(s) as sole indication for ICU admission. Primary outcomes were adverse events (intubation, pneumonia, death), which we classified as meriting ICU admission. We utilized Cribari matrices to calculate triage rates. RESULTS: 101 patients met study criteria. 12% had adverse events occurring on average at day 5. Our undertriage rate was 6% and overtriage rate 87%. The 72 overtriaged patients utilized 295 total ICU days. Evaluating guideline modification, ≥3 fractures appears optimal. Changing to this would have liberated 50 ICU days with 3% undertriage. CONCLUSION: Elderly patients with small numbers of rib fractures are overtriaged to ICUs. Modifying guidelines to ≥3 rib fractures will improve resource utilization and save ICU beds.
