Validity of A new Weaning Index of Discontinuation From Mechanical Ventilation in Intensive Care Unit

Abstract Background Failure to wean from mechanical ventilation (MV) is a frequent problem in the intensive care unit (ICU) setting. Herein, we investigate a new WI measured at the initial spontaneous breathing trial (SBT) in order to predict successful liberation from MV in mechanically ventilated ICU cases. Patients and methods This prospective cross-sectional study consisted of two phases; Phase I was designed to create a new WI from the criteria of 60 mechanically ventilated patients, while Phase II aimed to assess the accuracy of that index in another 40 patients. Patients aged older than 18 years who were receiving controlled-mode MV from day 3 to day 14 and planned to be weaned off MV were included in our study. Contrarily, patients with prior history of poor tolerance to SBT, weaning failure were excluded. Additionally, we also excluded patients with neurological or neuromuscular disorders, tracheostomy, pregnancy, or an active COVID-19 infection. Results The incidence of failed weaning was 33.3% in phase I, and 35% in phase II. Pulmonary causes were the most common indication in both groups. Multivariate regression analysis was done for phase I variables, and the following equation was created; (((Cough strength* 0.743) - 1.927) *0.05 + ((PaCO2 (mmHg)* - 0.126) + 6.786) *0.08 + ((mean airway pressure (CmH2O) * -1.304) + 14.119) *0.193 + ((PaO2/FIO2 * 0.268) - 58.555) *0.328 + ((rapid shallow breathing index * -0.485) + 24.406) *0.353). Using a cut-off value of > 0.69 and applying this index in phase II, it showed a mean value of -1.43 and 4.67 in the failure and success groups, respectively (p < 0.001). This new WI with cutoff value (> 0.69) had 88.5% sensitivity, 57.1% specificity, and a 77.5% accuracy to predict the success of weaning from MV. Conclusion We developed a new WI with good sensitivity and moderate specificity for predicting successful weaning from MV in ICU patients. Its use should be encouraged in the ICU setting, especially by less experienced ICU physicians.

Implementation of a cardiogenic shock team in a tertiary academic center

ObjectiveObservational studies have shown that the management of patients with cardiogenic shock (CS) by dedicated multidisciplinary teams improves clinical outcomes. Nevertheless, these studies reflect a specific organizational setting with most patients being transferred from referring hospitals, hospitalized in cardiac intensive care units (ICU), or treated with mechanical circulatory support (MCS) devices. The purpose of this study was to document the organization and outcomes of a CS team offering acute care in an all-comer population. MethodsA CS team was developed in a large academic tertiary institution. The team consisted of emergency care physicians, critical care cardiologists, interventional cardiologists, cardiac surgeons, ICU physicians, and heart failure specialists and was supported by a predefined operating protocol, a dedicated communication platform, and regular team meetings. ResultsOver 12 months, 70 CS patients (69 ± 13 years old, 67% males) were included. Acute myocardial infarction (AMI-CS) was the most common cause (64%); 31% of the patients presented post-resuscitated cardiac arrest and 56% needed invasive mechanical ventilation (IMV). Coronary angiography was performed in 70% and 53% had percutaneous coronary intervention. MCS was used in 10% and 6% were referred for urgent cardiac surgery. The in-hospital mortality in our center was 40% with 39% of the patients dying within 24 h from presentation. Overall, 76% of the live patients were discharged home. ConclusionAcross an all-comer population, AMI was the most common cause of CS. A significant number of patients presented post-cardiac arrest, and the majority required IMV. Mortality was high with a significant number dying within hours of presentation.

A Culture of Early Mobilization in Adult Intensive Care Units: Perspective and Competency of Physicians.

Early mobility (EM) is vital in the intensive care unit (ICU) to counteract immobility-related effects. A multidisciplinary approach is key, as it requires precise initiation knowledge. However, physicians' understanding of EM in adult ICU settings remains unexplored. This study was conducted to investigate the knowledge and clinical competency of physicians working in adult ICUs toward EM. This cross-sectional study enrolled 236 physicians to assess their knowledge of EM. A rigorously designed survey comprising 30 questions across the demographic, theoretical, and clinical domains was employed. The criteria for knowledge and competency were aligned with the minimum passing score (70%) stipulated for physician licensure by the medical regulatory authority in Saudi Arabia. Nearly 40% of the respondents had more than 5 years of experience. One-third of the respondents received theoretical knowledge about EM as part of their residency training, and only 4% of the respondents attended formal courses to enhance their knowledge. Almost all the respondents (95%) stated their awareness of EM benefits and its indications and contraindications and considered it safe to mobilize patients on mechanical ventilators. However, 62.3% of the respondents did not support EM for critically ill patients on mechanical ventilators until weaning. In contrast, 51.7% of respondents advised EM for agitated patients with RASS > 2. Only 113 (47.9%) physicians were competent in determining the suitability of ICU patients for EM. For critically ill patients who should be mobilized, nearly 60% of physicians refused to initiate EM. This study underscores insufficient practical knowledge of ICU physicians about EM criteria, which leads to suboptimal decisions, particularly in complex ICU cases. These findings emphasize the need for enhanced training and education of physicians working in adult ICU settings to optimize patient care and outcomes in critical care settings.

Inadequate intensive care physician supply in France: a point-prevalence prospective study

BackgroundThe COVID-19 pandemic has highlighted the importance of intensive care units (ICUs) and their organization in healthcare systems. However, ICU capacity and availability are ongoing concerns beyond the pandemic, particularly due to an aging population and increasing complexity of care. This study aimed to assess the current and future shortage of ICU physicians in France, ten years after a previous evaluation. A national e-survey was conducted among French ICUs in January 2022 to collect data on ICU characteristics, medical staffing, individual physician characteristics, and education and training capacities.ResultsAmong 290 ICUs contacted, 242 responded (response rate: 83%), representing 4943 ICU beds. The survey revealed an overall of 300 full time equivalent (FTE) ICU physician vacancies in the country. Nearly two-thirds of the participating ICUs reported at least one physician vacancy and 35% relied on traveling physicians to cover shifts. The ICUs most affected by physician vacancies were the ICUs of non-university affiliated public hospitals. The retirements expected in the next five years represented around 10% of the workforce. The median number of physicians per ICU was 7.0, corresponding to a ratio of 0.36 physician (FTE) per ICU bed. In addition, 27% of ICUs were at risk of critical dysfunction or closure due to vacancies and impending retirements.ConclusionThe findings highlight the urgent need to address the shortage of ICU physicians in France. Compared to a similar study conducted in 2012, the inadequacy between ICU physician supply and demand has increased, resulting in a higher number of vacancies. Our study suggests that, among others, increasing the number of ICM residents trained each year could be a crucial step in addressing this issue. Failure to take appropriate measures may lead to further closures of ICUs and increased risks to patients in this healthcare system.

Semiotics of ICU Physicians' Views on End-of-life Care and Quality of Dying in a Critical Care Setting: A Qualitative Study.

While intensive care unit (ICU) mortality rates in India are higher when compared to countries with more resources, fewer patients with clinically futile conditions are subjected to limitation of life-sustaining treatments or given access to palliative care. Although a few surveys and audits have been conducted exploring this phenomenon, the qualitative perspectives of ICU physicians regarding end-of-life care (EOLC) and the quality of dying are yet to be explored. There are 22 eligible consultant-level ICU physicians working in multidisciplinary ICUs were purposively recruited and interviewed. The study data was analyzed using reflexive thematic analysis (RTA) with a critical realist perspective, and the study findings were interpreted using the lens of the semiotic theory that facilitated the development of themes. About four themes were generated. Intensive care unit physicians perceived the quality of dying as respecting patients' and families' choices, fulfilling their needs, providing continued care beyond death, and ensuring family satisfaction. To achieve this, the EOLC process must encompass timely decision-making, communication, treatment guidelines, visitation rights, and trust-building. The contextual challenges were legal concerns, decision-making complexities, cost-related issues, and managing expectations. To improve care, ICU physicians suggested amplifying patient and family voices, building therapeutic relationships, mitigating conflicts, enhancing palliative care services, and training ICU providers in EOLC. Effective management of critically ill patients with life-limiting illnesses in ICUs requires a holistic approach that considers the complex interplay between the EOLC process, its desired outcome, the quality of dying, care context, and the process of meaning-making by ICU physicians.

ICU Staffing in the United States

BackgroundThe last national estimates of US intensive care unit (ICU) physician staffing are 25 years old and lack information about interprofessional teams. Research QuestionHow are US adult ICUs currently staffed? Study Design and MethodsWe conducted a cross-sectional survey (05/04/2022-02/02/2023) of adult ICU clinicians (targeting nurse/physician leadership) contacted using 2020 American Hospital Association (AHA) database information and, secondarily, through professional organizations. The survey included questions about interprofessional ICU staffing availability and roles at steady-state (pre-COVID-19). We linked survey data to hospital data in the AHA database to create weighted national estimates by extrapolating ICU staffing data to non-respondent hospitals based on hospital characteristics. ResultsThe cohort consisted of 596 adult ICUs (response rates—AHA contacts: 2.1%; professional organizations: unknown) with geographic diversity and size variability (median [interquartile range]: 20 [12,25] beds); most cared for mixed populations (414 [69.5%]), yet medical (55 [9.2%]), surgical (70 [11.7%]), and specialty (57 [9.6%]) ICUs were well represented. 554 (93.0%) had intensivists available, with intensivists covering all patients in 75.6% of these and onsite 24 hours/day in half (53.3% weekdays; 51.8% weekends). Of all ICUs, 69.8% had physicians-in-training and 77.7% nurse practitioners/physician assistants. For mechanically ventilated patients, nurse:patient ratios were 1:2 in 89.6%. Clinical pharmacists were available in 92.6%, and respiratory therapists in 98.8%. We estimated 85.1% (95% confidence interval: 85.7%, 84.5%) of hospitals nationally had ICUs with intensivists, 51.6% (50.6%, 52.5%) with physicians-in-training, 72.1% (71.3%, 72.9%) with nurse practitioners/physician assistants, 98.5% (98.4%, 98.7%) with respiratory therapists, and 86.9% (86.4%, 87.4%) with clinical pharmacists. For mechanically ventilated patients, 86.4% (85.8%, 87.0%) used 1:2 nurses:patients. InterpretationIntensivist presence in adult US ICUs has greatly increased over 25 years. Intensivists, respiratory therapists, and clinical pharmacists are commonly available, and each nurse usually provides care for two mechanically ventilated patients. However, team composition and workload vary.

Workplace violence against physicians in intensive care units in Turkey: A cross-sectional study.

Background Although there are many studies on violence against physicians in the literature, there are few studies on violence against physicians working in intensive care units (ICUs). We aimed to investigate the frequency, type and underlying factors of violence against physicians working in ICUs in Turkey in the past 1 year. Methods We collected data by sending a questionnaire about violence against physicians working in ICUs via e-mail and WhatsApp between 1 and 15 May 2022. IBM SPSS Statistics V.24.0 was used for data analysis. The chi-square test and Fisher precision test were used to compare categorical data. Results Over one-third (38.6%) of the 354 physicians participating in our study reported that they had been exposed to violence in the past year, while 20.7% reported that they had been exposed to violence more than once in the past year. There was a significant relationship between the frequency of exposure to violence, female gender, age group, title, subspecialization status, working style and duration of working in the ICU (p<0.05). There was no relationship between the working area, type of hospital and ICU and exposure to violence (p>0.05). The presence of restriction and control points at the entrance to ICUs prevented violence (p<0.05). Conclusion Physicians working in ICUs encounter violence against them. The frequency of violence increased after the Covid-19 pandemic. A significant relationship was found between the frequency of violence and female gender, age group, title, subspecialization status, working style and duration of working in ICUs.

Clinical impact of a cardiac intensivist in an adult cardiac care unit from the RESCUE registry

Abstract Funding Acknowledgements None. Purpose Dedicated intensive care unit (ICU) physician staffing is assocated with a reduction in ICU mortality rates in general medical and surgical ICUs. However, limited data area available on the role of cardiac intensivist in the cardiac intensive care unit (CICU). We investigated the association of cardiac intensivist-directed care with clinical outcomes in adult patients admitted to the CICU. Methods The SMART-RESCUE study is a multicenter, retrospective and prosective registry of patients that presented witth cardiogenic shock (CS). Between January 2014 and December 2018, 1,247 patients with CS were enrolled from 12 major centers in Korea. The study population was divided into 2 groups, according to the presence of a cardiac intensivist. The primary outcome was in-hospital mortality. Results THe analysis with SMART-RESCUE registry included 1,247 patients with CS (n=552 in the group with cardiac intensivist and n=695 in the group without cardiac intensivist) (Table 1). The in-hospital survival rate was significant higher in the group with intensivist than that in the group without intensivist (72.1% vs 59.2%, p &amp;lt; 0.001) (Figure 1). Cardiac intensive care with cardiac intensivist was associated with a reduction in risk-adjusted in-hospital mortality (adjusted odds ratio for in hospital death, 0.53; 95% confidence interval: 0.401 to 0.704; p &amp;lt; 0.001). Survival analysis also revealed significantly higher death free survival in te group with intensitivst. In multivariable analysis, cardiac intensivist, chronic kidney disease, ECMO-cardiopulmonary resuscitation, ST elevation myocardial infarction presentation and vasotrope-inotrope score were selected to be significant prognostic predictors for death in the CICU. Concluison: The presence of a dedicated cardiac intensivist was associated with a reduction in hospital mortality rates in patients with cardiovascular disease who required critical care.

Identifying the risk factors of ICU-acquired fungal infections: clinical evidence from using machine learning.

Fungal infections are associated with high morbidity and mortality in the intensive care unit (ICU), but their diagnosis is difficult. In this study, machine learning was applied to design and define the predictive model of ICU-acquired fungi (ICU-AF) in the early stage of fungal infections using Random Forest. This study aimed to provide evidence for the early warning and management of fungal infections. We analyzed the data of patients with culture-positive fungi during their admission to seven ICUs of the First Affiliated Hospital of Chongqing Medical University from January 1, 2015, to December 31, 2019. Patients whose first culture was positive for fungi longer than 48 h after ICU admission were included in the ICU-AF cohort. A predictive model of ICU-AF was obtained using the Least Absolute Shrinkage and Selection Operator and machine learning, and the relationship between the features within the model and the disease severity and mortality of patients was analyzed. Finally, the relationships between the ICU-AF model, antifungal therapy and empirical antifungal therapy were analyzed. A total of 1,434 cases were included finally. We used lasso dimensionality reduction for all features and selected six features with importance ≥0.05 in the optimal model, namely, times of arterial catheter, enteral nutrition, corticosteroids, broadspectrum antibiotics, urinary catheter, and invasive mechanical ventilation. The area under the curve of the model for predicting ICU-AF was 0.981 in the test set, with a sensitivity of 0.960 and specificity of 0.990. The times of arterial catheter (p = 0.011, OR = 1.057, 95% CI = 1.053-1.104) and invasive mechanical ventilation (p = 0.007, OR = 1.056, 95%CI = 1.015-1.098) were independent risk factors for antifungal therapy in ICU-AF. The times of arterial catheter (p = 0.004, OR = 1.098, 95%CI = 0.855-0.970) were an independent risk factor for empirical antifungal therapy. The most important risk factors for ICU-AF are the six time-related features of clinical parameters (arterial catheter, enteral nutrition, corticosteroids, broadspectrum antibiotics, urinary catheter, and invasive mechanical ventilation), which provide early warning for the occurrence of fungal infection. Furthermore, this model can help ICU physicians to assess whether empiric antifungal therapy should be administered to ICU patients who are susceptible to fungal infections.

The current state of intensive care unit discharge practices - Results of an international survey study.

Increasing pressure on limited intensive care capacities often requires a subjective assessment of a patient's discharge readiness in the absence of established Admission, Discharge, and Transfer (ADT) guidelines. To avoid suboptimal care transitions, it is important to define clear guidelines for the admission and discharge of intensive care patients and to optimize transfer processes between the intensive care unit (ICU) and lower care levels. To achieve these goals, structured insights into usual ICU discharge and transfer practices are essential. This study aimed to generate these insights by focusing on involved stakeholders, established processes, discharge criteria and tools, relevant performance metrics, and current barriers to a timely and safe discharge. In 2022, a structured, web-based, anonymous cross-sectional survey was conducted, aimed at practicing ICU physicians, nurses, and bed coordinators. The survey consisted of 29 questions (open, closed, multiple choice, and scales) that were divided into thematic blocks. The study was supported by several national and international societies for intensive care medicine and nursing. A total of 219 participants from 40 countries (105 from Germany) participated in the survey. An overload of acute care resources with ~90% capacity utilization in the ICU and the general ward (GW) leads to not only premature but also delayed patient transfers due to a lack of available ward and intermediate care (IMC) beds. After multidisciplinary rounds within the intensive care team, the ICU clinician on duty usually makes the final transfer decision, while one-third of the panel coordinates discharge decisions across departmental boundaries. By the end of the COVID-19 pandemic, half of the hospitals had implemented ADT policies. Among these hospitals, nearly one-third of the hospitals had specific transfer criteria established, consisting primarily of vital signs and laboratory data, patient status and autonomy, and organization-specific criteria. Liaison nurses were less common but were ranked right after the required IMC capacities to bridge the care gap between the ICU and normal wards. In this study, 80% of the participants suggested that transfer planning would be easier if there was good transparency regarding the capacity utilization of lower care levels, a standardized transfer process, and improved interdisciplinary communication. To improve care transitions, transfer processes should be managed proactively across departments, and efforts should be made to identify and address care gaps.

A novel nomogram for the prediction of subsyndromal delirium in patients in intensive care units: A prospective, nested case-controlled study

BackgroundSubsyndromal delirium is a dynamic, recognizable condition commonly observed in intensive care unit (ICU) patients that can lead to poor patient prognosis, and its prompt recognition and management can prevent disease progression. However, no evidence-based predictive tool has been developed specifically to assess the occurrence of subsyndromal delirium in the ICU. ObjectiveTo develop and validate a novel, simple and effective tool for estimating the risk of subsyndromal delirium among ICU patients. DesignA prospective, nested case-controlled study. Data sourcesA total of 731 patients were recruited from the central ICU of a tertiary hospital in southwestern China from August 2021 to November 2022. MethodsThe least absolute shrinkage and selection operator was applied to screen potential features for univariate and multivariate logistic regression. A nomogram was constructed using the selected variables. The performance of the nomogram was evaluated by combining the area under the receiver operating characteristic curve (AUC), calibration curves and decision curve analysis (DCA). ResultsThe prevalence of subsyndromal delirium among ICU patients was 23.06 %. Multiple logistic regression analysis revealed that the independent predictive factors for subsyndromal delirium among ICU patients were vision impairment, a history of falls, the use of restraint, blood transfusion, the use of antibiotics, surgery, the Caprini score, and the Braden score, all of which were used to construct the nomogram. The AUCs for the model were 0.710 (95 % CI, 0.654–0.766, P < 0.001) and 0.825 (95 % CI, 0.732–0.917, P < 0.001) in the training and validation cohorts, respectively, indicating that the model had high accuracy in distinguishing patients with and without subsyndromal delirium. The calibration curve of the nomogram showed good consistency between the predicted and actual probabilities. The DCA indicated that the nomogram has clinical application for patients in the ICU. ConclusionsWe developed an easy-to-use nomogram for identifying subsyndromal delirium in ICU patients with satisfactory predictive ability based on simple and easily accessible clinical features. The nomogram can identify ICU patients at high-risk for subsyndromal delirium and may be a useful subsyndromal delirium tool for current ICU physicians.

Analysis of clinical treatment of acute respiratory distress syndrome assisted by artificial intelligence

To evaluate the clinical practice of intensive care unit (ICU) physicians at Hebei General Hospital in identifying patients meeting the diagnostic criteria for acute respiratory distress syndrome (ARDS) and the current status of invasive mechanical ventilation management and adjunctive therapy in these patients, and to analyze the incidence and clinical outcomes of ARDS. A retrospective cohort study was conducted. The patients who were hospitalized in the ICU of Hebei General Hospital from April 10, 2017 to June 30, 2022 and met the Berlin definition diagnostic criteria for ARDS were enrolled as study subjects. Artificial intelligence (AI) technology was applied to search the basic information (age, gender, height, body weight, etc.), auxiliary examination, electronic medical record, non-drug doctor's advice, drug doctor's advice, critical report, scoring system, monitoring master table and other data of the above medical records in the electronic medical record system of the hospital. The first set of laboratory indicators sequentially retrieved from the system daily from 05:00 to 10:00 and vital signs and mechanical ventilation-related parameters recorded in the "critical care report" at 06:00 daily were extracted, and outcome indicators of the patients were collected. After screening and analysis, a total of 255 patients who met the ARDS diagnostic criteria were finally enrolled. The overall incidence of ARDS in the ICU accounted for 3.4% (255/7 434) of the total number of ICU patients, of which mild, moderate and severe ARDS accounted for 22.4% (57/255), 49.0% (125/255), and 28.6% (73/255), respectively, while the recognition rates of clinical doctors were 71.9% (41/57), 58.4% (73/125) and 71.2% (52/73), respectively. During the ICU stay, 250 patients (98.0%) received only invasive mechanical ventilation, while 5 patients (2.0%) received both non-invasive and invasive mechanical ventilation. The tidal volume/ideal body weight of ARDS patients was 7.64 (6.49, 9.01) mL/kg, and the positive end-expiratory pressure (PEEP) was 8.0 (5.0, 10.0) cmH2O (1 cmH2O ≈ 0.098 kPa). In addition, during the diagnosis and detection of ARDS, only 7 patients were recorded the platform pressure and 6 patients were recorded the drive pressure. Regarding adjunctive therapies, 137 patients (53.7%) received deep sedation, 26 patients (10.2%) underwent lung recruitment, 55 patients (21.6%) received prone ventilation, 42 patients (16.5%) were treated with high-dose steroids, 19 patients (7.5%) were treated with neuromuscular blockade, and 8 patients (3.1%) were treated with extracorporeal membrane oxygenation (ECMO). Finally, 70 patients (27.5%) were discharged automatically, while 50 patients (19.6%) died in the ICU, of which the ICU mortality of mild, moderate, and severe ARDS patients were 15.8% (9/57), 22.4% (28/125), and 17.8% (13/73), respectively. After follow-up, it was found that all 70 patients discharged automatically died within 28 days after discharge, and the overall ICU mortality adjusted accordingly was 47.1% (120/255). The overall incidence of ARDS in ICU patients at Hebei General Hospital is relatively low, with a high recognition rate by clinical physicians. Despite the high level of compliance and implementation of lung protective ventilation strategies and auxiliary treatment measures, it is still necessary to further improve the level of standardization in the implementation of small tidal volume and respiratory mechanics monitoring. For the implementation of auxiliary measures such as prone ventilation, it is necessary to further improve the enthusiasm of medical staff. The mortality in ICU is relatively low in ARDS patients, while the rate of spontaneous discharge is relatively high.

Perceptions of Quality of Interprofessional Collaboration, Staff Well-Being and Nonbeneficial Treatment: A Comparison between Nurses and Physicians in Intensive and Palliative Care.

This study assessed differences in interprofessional collaboration, perception of nonbeneficial care, and staff well-being between critical care and palliative care teams. In six German hospitals, a staff survey was conducted between December 2013 and March 2015 among nurses and physicians in intensive and palliative care units. To allow comparability between unit types, a matching was performed for demographic characteristics of staff. N = 313 critical care and 79 palliative care staff participated, of which 72 each were successfully matched. Critical care nurses perceived the poorest overall quality of collaboration compared with critical care physicians and palliative care physicians and nurses. They also reported less inclusive leadership from attendings and head nurses, and the least collaboration on care decisions with physicians. They were most likely to perceive nonbeneficial care, and they reported the lowest levels of job satisfaction and the highest intention to leave the job. In partial correlations, aspects of high-quality collaboration were associated with less perceived nonbeneficial care and higher staff well-being for both critical care and palliative care staff. Our findings indicate that critical care teams could improve collaboration and enhance well-being, particularly among nurses, by adopting principles of collaborative work culture as established in palliative care.

Experiences with and needs for aftercare following the death of a loved one in the ICU: a mixed-methods study among bereaved relatives

BackgroundBereaved relatives of intensive care unit (ICU) patients are at increased risk of psychological complaints. Aftercare might help them cope with processing the ICU admission and their loved one’s death. There is little (qualitative) evidence on how bereaved relatives experience aftercare. Also, the COVID-19 pandemic likely impacted aftercare provision. We aim to examine how many relatives in Dutch ICUs received aftercare before and during the pandemic and to qualitatively describe their experiences and needs regarding aftercare.MethodsA mixed-methods study among relatives of patients who died in an ICU before or during the COVID-19 pandemic. Bereaved relatives in six ICUs completed a questionnaire (n = 90), including two items on aftercare. These were analyzed using descriptive statistics and Chi-squared tests. Subsequently, both relatives that received and relatives that did not receive aftercare were interviewed about their experiences and needs regarding aftercare. The interviews were thematically analyzed.ResultsAfter the passing of a loved one, 44% of the relatives were asked by a healthcare professional from the hospital how they were doing, and 26% had had a follow-up conversation. Both happened more often during the first wave of the pandemic than during the second wave or before the pandemic. The most common reason for not having had a follow-up conversation was not knowing about this option (44%), followed by not feeling a need (26%). Regarding the latter, interviewed relatives explained that this would not revive their loved one or that they had already discussed everything they wanted. Relatives who wanted a follow-up conversation, wanted this because this would help them realize the severity of their loved one’s illness, to exchange personal experiences, and/or to thank the ICU team. Those with a follow-up conversation said that they had reviewed the medical course of the admission and/or discussed their (mental) well-being.ConclusionsICU healthcare professionals may play a vital role in addressing aftercare needs by asking relatives how they are doing in the weeks following the death of their loved one and offering them a follow-up conversation with an ICU physician. We recommend to include aftercare for bereaved relatives in ICU guidelines.

Bacterial Community- and Hospital-Acquired Pneumonia in Patients with Critical COVID-19-A Prospective Monocentric Cohort Study.

The impact of bacterial pneumonia on patients with COVID-19 infection remains unclear. This prospective observational monocentric cohort study aims to determine the incidence of bacterial community- and hospital-acquired pneumonia (CAP and HAP) and its effect on mortality in critically ill COVID-19 patients admitted to the intensive care unit (ICU) at University Hospital Olomouc between 1 November 2020 and 31 December 2022. The secondary objectives of this study include identifying the bacterial etiology of CAP and HAP and exploring the capabilities of diagnostic tools, with a focus on inflammatory biomarkers. Data were collected from the electronic information hospital system, encompassing biomarkers, microbiological findings, and daily visit records, and subsequently evaluated by ICU physicians and clinical microbiologists. Out of 171 patients suffering from critical COVID-19, 46 (27%) had CAP, while 78 (46%) developed HAP. Critically ill COVID-19 patients who experienced bacterial CAP and HAP exhibited higher mortality compared to COVID-19 patients without any bacterial infection, with rates of 38% and 56% versus 11%, respectively. In CAP, the most frequent causative agents were chlamydophila and mycoplasma; Enterobacterales, which were multidrug-resistant in 71% of cases; Gram-negative non-fermenting rods; and Staphylococcus aureus. Notably, no strains of Streptococcus pneumoniae were detected, and only a single strain each of Haemophilus influenzae and Moraxella catarrhalis was isolated. The most frequent etiologic agents causing HAP were Enterobacterales and Gram-negative non-fermenting rods. Based on the presented results, commonly used biochemical markers demonstrated poor predictive and diagnostic accuracy. To confirm the diagnosis of bacterial CAP in our patient cohort, it was necessary to assess the initial values of inflammatory markers (particularly procalcitonin), consider clinical signs indicative of bacterial infection, and/or rely on positive microbiological findings. For HAP diagnostics, it was appropriate to conduct regular detailed clinical examinations (with a focus on evaluating respiratory functions) and closely monitor the dynamics of inflammatory markers (preferably Interleukin-6).

Spanish Translation and Cultural Adaptation of the Intensive Care Unit Delirium Playbook.

A lack of high-quality provider education hinders the delivery of standard-of-care delirium detection and prevention practices in the intensive care unit (ICU). To fill this gap, we developed and validated an e-learning ICU Delirium Playbook consisting of eight videos and a 44-question knowledge assessment quiz. Given the increasing Spanish-speaking population worldwide, we translated and cross-culturally adapted the playbook from English into Spanish. To translate and culturally adapt the ICU Delirium Playbook into Spanish, the second most common native language worldwide. The translation and cross-cultural adaptation process included double forward and back translations and harmonization by a 14-person interdisciplinary team of ICU nurses and physicians, delirium experts, methodologists, medical interpreters, and bilingual professionals representing many Spanish-speaking global regions. After a preeducation quiz, a nurse focus group completed the playbook videos and posteducation quiz, followed by a semistructured interview. The ICU Delirium Playbook: Spanish Version maintained conceptual equivalence to the English version. Focus group participants posted mean (standard deviation) pre- and post-playbook scores of 63% (10%) and 78% (12%), with a 15% (11%) pre-post improvement (P = 0.01). Participants reported improved perceived competency in performing the Confusion Assessment Method for the ICU and provided positive feedback regarding the playbook. After translation and cultural adaptation, the ICU Delirium Playbook: Spanish Version yielded significant knowledge assessment improvements and positive feedback. The Spanish playbook is now available for public dissemination.

Trainee-supervisor collaboration, progress-visualisation, and coaching: a survey on challenges in assessment of ICU trainees.

Assessing trainees is crucial for development of their competence, yet it remains a challenging endeavour. Identifying contributing and influencing factors affecting this process is imperative for improvement. We surveyed residents, fellows, and intensivists working in an intensive care unit (ICU) at a large non-university hospital in Switzerland to investigate the challenges in assessing ICU trainees. Thematic analysis revealed three major themes. Among 45 physicians, 37(82%) responded. The first theme identified is trainee-intensivist collaboration discontinuity. The limited duration of trainees' ICU rotations, large team size operating in a discordant three-shift system, and busy and unpredictable day-planning hinder sustained collaboration. Potential solutions include a concise pre-collaboration briefing, shared bedside care, and post-collaboration debriefing involving formative assessment and reflection on collaboration. The second theme is the lack of trainees' progress visualisation, which is caused by unsatisfactory familiarisation with the trainees' development. The lack of an overview of a trainee's previous achievements, activities, strengths, weaknesses, and goals may result in inappropriate assessments. Participants suggested implementing digital assessment tools, a competence committee, and dashboards to facilitate progress visualisation. The third theme we identified is insufficient coaching and feedback. Factors like personality traits, hierarchy, and competing interests can impede coaching, while high-quality feedback is essential for correct assessment. Skilled coaches can define short-term goals and may optimise trainee assessment by seeking feedback from multiple supervisors and assisting in both formative and summative assessment. Based on these three themes and the suggested solutions, we developed the acronym "ICU-STAR" representing a potentially powerful framework to enhance short-term trainee-supervisor collaboration in the workplace and to co-scaffold the principles of adequate assessment. According to ICU physicians, trainee-supervisor collaboration discontinuity, the lack of visualisation of trainee's development, and insufficient coaching and feedback skills of supervisors are the major factors hampering trainees' assessment in the workplace. Based on suggestions by the survey participants, we propose the acronym "ICU-STAR" as a framework including briefing, shared bedside care, and debriefing of the trainee-supervisor collaboration at the workplace as its core components. With the attending intensivists acting as coaches, progress visualisation can be enhanced by actively collecting more data points. N/A.

Kalıpyargı Tehditinin Kardiopulmoner Resüsitasyon Performansı Üzerine Etkisi: Bir Randomize Kontrollü Manken Çalışması

Objective: Stereotype threat (ST) can lead to decreased performance when individuals face the possibility of confirming negative stereotypes associated with their group. During the Coronavirus disease 2019 (COVID-19) pandemic, non-Intensive Care Unit physicians (non-ICUp) were assigned to work in ICUs. However, social media emphasized the inadequacy of knowledge and skills among these physicians. Given the negative judgments, the study aimed to evaluate the cardiopulmonary resuscitation (CPR) performances of these physicians and investigate the effect of ST. Methods: A total of 63 non-ICUp and 53 Intensive Care Unit physicians (ICUp) physicians working in COVID-19 ICUs were randomly assigned to control and experimental groups. In the experimental group, ST was manipulated by presenting the study’s aim as measuring the difference in CPR performances between ICUp and non-ICUp physicians. The control group received no information. Participants were videotaped while performing a standard CPR scenario and evaluated by independent instructors and mannequin scores. Results: Overall CPR scores were higher among ICUp. Non-ICUp performed better in the ST condition regarding effective chest compression (p=.02) and correct compression rates per minute (p=.02) compared to the control condition. However, ICUp had lower scores for correctly placing chest compressions in the ST condition (p=.03). Conclusion: The higher CPR performance among ICUp was expected. However, the hypothesis suggesting lower performance for non-ICUp under ST conditions was not supported. Inconsistent results regarding the ST effect could be influenced by moderating factors such as task difficulty, knowledge about the existing stereotype, and motivation to perform well. The interaction between the physicians’ specialty and situational factors highlights the importance of creating realistic training environments that simulate high-pressure situations, ultimately contributing to the development of competent and confident healthcare professionals. Future research should further explore the impact of ST-based training on interactions and performance among different healthcare professionals.

A Novel Continuous Real-Time Vital Signs Viewer for Intensive Care Units: Design and Evaluation Study.

Clinicians working in intensive care units (ICUs) are immersed in a cacophony of alarms and a relentless onslaught of data. Within this frenetic environment, clinicians make high-stakes decisions using many data sources and are often oversaturated with information of varying quality. Traditional bedside monitors only depict static vital signs data, and these data are not easily viewable remotely. Clinicians must rely on separate nursing charts-handwritten or electric-to review physiological patterns, including signs of potential clinical deterioration. An automated physiological data viewer has been developed to provide at-a-glance summaries and to assist with prioritizing care for multiple patients who are critically ill. This study aims to evaluate a novel vital signs viewer system in a level 1 trauma center by subjectively assessing the viewer's utility in a high-volume ICU setting. ICU attendings were surveyed during morning rounds. Physicians were asked to conduct rounds normally, using data reported from nurse charts and briefs from fellows to inform their clinical decisions. After the physician finished their assessment and plan for the patient, they were asked to complete a questionnaire. Following completion of the questionnaire, the viewer was presented to ICU physicians on a tablet personal computer that displayed the patient's physiologic data (ie, shock index, blood pressure, heart rate, temperature, respiratory rate, and pulse oximetry), summarized for up to 72 hours. After examining the viewer, ICU physicians completed a postview questionnaire. In both questionnaires, the physicians were asked questions regarding the patient's stability, status, and need for a higher or lower level of care. A hierarchical clustering analysis was used to group participating ICU physicians and assess their general reception of the viewer. A total of 908 anonymous surveys were collected from 28 ICU physicians from February 2015 to June 2017. Regarding physicians' perception of whether the viewer enhanced the ability to assess multiple patients in the ICU, 5% (45/908) strongly agreed, 56.6% (514/908) agreed, 35.3% (321/908) were neutral, 2.9% (26/908) disagreed, and 0.2% (2/908) strongly disagreed. Morning rounds in a trauma center ICU are conducted in a busy environment with many data sources. This study demonstrates that organized physiologic data and visual assessment can improve situation awareness, assist clinicians with recognizing changes in patient status, and prioritize care.

Mobile Application–Based Communication Facilitation Platform for Family Members of Critically Ill Patients

Unmet and racially disparate palliative care needs are common in intensive care unit (ICU) settings. To test the effect of a primary palliative care intervention vs usual care control both overall and by family member race. This cluster randomized clinical trial was conducted at 6 adult medical and surgical ICUs in 2 academic and community hospitals in North Carolina between April 2019 and May 2022 with physician-level randomization and sequential clusters of 2 Black patient-family member dyads and 2 White patient-family member dyads enrolled under each physician. Eligible participants included consecutive patients receiving mechanical ventilation, their family members, and their attending ICU physicians. Data analysis was conducted from June 2022 to May 2023. A mobile application (ICUconnect) that displayed family-reported needs over time and provided ICU attending physicians with automated timeline-driven communication advice on how to address individual needs. The primary outcome was change in the family-reported Needs at the End-of-Life Screening Tool (NEST; range 0-130, with higher scores reflecting greater need) score between study days 1 and 3. Secondary outcomes included family-reported quality of communication and symptoms of depression, anxiety, and posttraumatic stress disorder at 3 months. A total of 111 (51% of those approached) family members (mean [SD] age, 51 [15] years; 96 women [86%]; 15 men [14%]; 47 Black family members [42%]; 64 White family members [58%]) and 111 patients (mean [SD] age, 55 [16] years; 66 male patients [59%]; 45 Black patients [41%]; 65 White patients [59%]; 1 American Indian or Alaska Native patient [1%]) were enrolled under 37 physicians randomized to intervention (19 physicians and 55 patient-family member dyads) or control (18 physicians and 56 patient-family member dyads). Compared with control, there was greater improvement in NEST scores among intervention recipients between baseline and both day 3 (estimated mean difference, -6.6 points; 95% CI, -11.9 to -1.3 points; P = .01) and day 7 (estimated mean difference, -5.4 points; 95% CI, -10.7 to 0.0 points; P = .05). There were no treatment group differences at 3 months in psychological distress symptoms. White family members experienced a greater reduction in NEST scores compared with Black family members at day 3 (estimated mean difference, -12.5 points; 95% CI, -18.9 to -6.1 points; P < .001 vs estimated mean difference, -0.3 points; 95% CI, -9.3 to 8.8 points; P = .96) and day 7 (estimated mean difference, -9.5 points; 95% CI, -16.1 to -3.0 points; P = .005 vs estimated mean difference, -1.4 points; 95% CI, -10.7 to 7.8; P = .76). In this study of ICU patients and family members, a primary palliative care intervention using a mobile application reduced unmet palliative care needs compared with usual care without an effect on psychological distress symptoms at 3 months; there was a greater intervention effect among White family members compared with Black family members. These findings suggest that a mobile application-based intervention is a promising primary palliative care intervention for ICU clinicians that directly addresses the limited supply of palliative care specialists.
