Associated Factors of Trauma Severity and Mortality in Pediatric Patients Admitted to Intensive Care Unit; a 10-Year Retrospective Study.

Introduction: Trauma is a significant global public health concern and the leading cause of morbidity and mortality in children. This study aimed to assess the independent predictors of trauma severity as well as mortality in pediatric patients admitted to the intensive care unit (ICU). Methods: In this cross-sectional study, following the STROBE checklist, we retrospectively analyzed the clinical and baseline characteristics of pediatric patients with trauma injuries admitted to the ICU of Children's Hospital of Zhejiang University School of Medicine, China, over a decade. Results: 951 pediatric patients with a mean age of 4.79 ± 3.24 years (60.78% Boys) were studied (mortality rate 8.41%). Significant associations were observed between ISS and place of residence (p = 0.021), location of the injury (p = 0.010), year of injury (p <0.001), and injury mechanism (p <0.001). The two independent factors of trauma severity were the year of injury (ß = 0.47; 95%CI: 0.28 - 0.65) and injury mechanism (ß = -0.60; 95%CI: -0.88 - -0.31). Significant differences were observed between survived and non-survived regarding age (p <0.001), ISS score (p <0.001), time elapsed from injury to ICU (p <0.001), duration of mechanical ventilation (p <0.001), GCS score (p <0.001), and the proportion of patients requiring mechanical ventilation (p <0.001 ). The results of multivariate analysis indicated that age (OR = 0.805; 95%CI: 0.70 - 0.914; p = 0.001) and GCS score at ICU admission (OR = 0.629; 95%CI: 0.53 - 0.735; p < 0.001) acted as protective factors, whereas mechanical ventilation in the ICU (OR = 7.834; 95%CI: 1.766 - 34.757; p = 0.007) and ISS score at ICU admission (OR = 1.088; 95%CI: 1.047 - 1.130; p < 0.001) served as risk factors for mortality. Conclusion: Automobile-related injuries represent the leading cause of trauma in children, with escalating severity scores year over year among pediatric patients admitted to the ICU with trauma injuries. Based on the findings the independent predictors of mortality of pediatric trauma patients admitted to the ICU were age, GCS score at ICU admission; mechanical ventilation in the ICU, and ISS score at ICU admission. Also, the year of injury and injury mechanism were independent predictors of trauma severity.

Percepción de los familiares de pacientes críticos en relación a la comunicación que le brinda el profesional de enfermería de la unidad de cuidados intensivos / Perception of the relatives of critically ill patients in relation to the communication pro-vided by the nursing professional of the intensive care unit

Introducción: cuando un individuo es hospitalizado en UCI para control y monitorización permanente de su salud, su cuidado está orientado específicamente a la asistencia plena de médicos y personal de enfermería. La complejidad de estos cuidados genera una crisis situacional y emocional en la familia que causa ansiedad, estrés, miedo y duda.

Introduction: health is the condition in which every living being enjoys absolute well-being both physically and mentally and socially, when it is affected either by a pathology or by general accidents; Given the physical condition of the individual, he or she is often hospitalized in the ICU for permanent control and monitoring. Your care is specifically oriented towards the full assistance of Doctors and Nurses. The complexity of this care generates a situational and emotional crisis in the immediate family that causes anxiety, stress, fear and doubt. The way in which the nurse supports the family member in critical or distressing situations is what will determine the perception of the family members towards the nurses, since communication and emotional support are part of the professional competence and contribute to the holistic care of the patient. patient and family. It is a care that is reflected in the feeling that the nurses have that when they do it, the families are very grateful and that, without a doubt, it is their job. Objective: Determine the perception of the patient's relatives regarding the communication provided by the nursing professional in the critical care unit of a private institution. Materials and Methods: A quantitative, descriptive and cross-sectional study was carried out. The sample was made up of 40 adult relatives responsible for the patient hospitalized in the Adult intensive care unit, during the months of June - September 2023. The information collection instrument was a questionnaire on "Perception of relatives of Critical Patients, regarding to Nursing intervention during their Situational Crisis"; It was used and validated by the author Franco Canales Rosa applied at the Edgardo Rebagliati National Hospital, April 2003. Results:The results show that the overall perception of family members is favorable, regarding verbal communication, non-verbal communication and emotional support[AU]

No substantial neurocognitive impact of COVID-19 across ages and disease severity: a multicenter biomarker study of SARS-CoV-2 positive and negative adult and pediatric patients with acute respiratory tract infections.

BACKGROUND: Compared to intensive care unit patients with SARS-CoV-2 negative acute respiratory tract infections, patients with SARS-CoV-2 are supposed to develop more frequently and more severely neurologic sequelae. Delirium and subsequent neurocognitive deficits (NCD) have implications for patients' morbidity and mortality. However, the extent of brain injury during acute COVID-19 and subsequent NCD still remain largely unexplored. Body-fluid biomarkers may offer valuable insights into the quantification of acute delirium, brain injury and may help to predict subsequent NCD following COVID-19. METHODS: In a multicenter, observational case-control study, conducted across four German University Hospitals, hospitalized adult and pediatric patients with an acute COVID-19 and SARS-CoV-2 negative controls presenting with acute respiratory tract infections were included. Study procedures comprised the assessment of pre-existing neurocognitive function, daily screening for delirium, neurological examination and blood sampling. Fourteen biomarkers indicative of neuroaxonal, glial, neurovascular injury and inflammation were analyzed. Neurocognitive functions were re-evaluated after three months. RESULTS: We enrolled 118 participants (90 adults, 28 children). The incidence of delirium [85 out of 90 patients (94.4%) were assessable for delirium) was comparable between patients with COVID-19 [16 out of 61 patients (26.2%)] and SARS-CoV-2 negative controls [8 out of 24 patients (33.3%); p > 0.05] across adults and children. No differences in outcomes as measured by the modified Rankin Scale, the Short-Blessed Test, the Informant Questionnaire on Cognitive Decline in the Elderly, and the pediatrics cerebral performance category scale were observed after three months. Levels of body-fluid biomarkers were generally elevated in both adult and pediatric cohorts, without significant differences between SARS-CoV-2 negative controls and COVID-19. In COVID-19 patients experiencing delirium, levels of GFAP and MMP-9 were significantly higher compared to those without delirium. CONCLUSIONS: Delirium and subsequent NCD are not more frequent in COVID-19 as compared to SARS-CoV-2 negative patients with acute respiratory tract infections. Consistently, biomarker levels of brain injury indicated no differences between COVID-19 cases and SARS-CoV-2 negative controls. Our data suggest that delirium in COVID-19 does not distinctly trigger substantial and persistent subsequent NCD compared to patients with other acute respiratory tract infections.

Epidemiology and outcomes of patients with tuberculosis requiring extracorporeal membrane oxygenation: An ELSO registry analysis.

PURPOSE: This study aimed to analyze data from the Extracorporeal Life Support Organization (ELSO) registry to elucidate the epidemiology and outcomes of patients with tuberculosis necessitating extracorporeal membrane oxygenation (ECMO), an intervention typically employed in treating severe acute respiratory distress syndrome (ARDS), but infrequently reported in tuberculosis contexts. METHODS: A retrospective analysis was conducted utilizing the ELSO registry data spanning from 2003 to 2022, specifically targeting patients with tuberculosis who underwent ECMO. Primary outcomes included survival to hospital discharge, while secondary outcomes encompassed pre-ECMO support, ECMO duration, complications, and discharge destinations. Univariate and multivariate Cox proportional hazard regression analyses were employed to identify factors influencing survival rates. RESULTS: The analysis included 169 patients with tuberculosis, with a median ECMO support duration of 233 h. The weaning success rate was recorded at 62.7 %, and 55 % of patients achieved survival to hospital discharge. Complications arose in 69.8 % of cases, predominantly mechanical complications (46.6 %). Multivariate Cox regression analysis identified complications (HR: 0.448, 95 % CI: 0.222-0.748, P=0.001), infections (HR: 0.483, 95 % CI: 0.241-0.808, P=0.001), and prolonged intervals from admission to ECMO initiation (HR: 0.698, 95 % CI: 0.396-0.901, P=0.018) as significant factors correlated with decreased survival likelihood. CONCLUSION: ECMO presents as a viable treatment option for patients with tuberculosis; however, timely initiation and meticulous management are critical to mitigate complications and enhance patient outcomes. IMPLICATION FOR CLINICAL PRACTICE: Accurate identification of optimal ECMO initiation timing for eligible patients with tuberculosis can significantly enhance clinical outcomes in critical care settings, such as intensive care units.

Family-Led Coaching of Patients During Weaning From Sedation and Mechanical Ventilation in the ICU.

BACKGROUND: ICU patients are weaned from sedation and mechanical ventilation through spontaneous awakening trials (SATs) and spontaneous breathing trials (SBTs). Weaning can be distressing for patients and their families. Family-led coaching could reassure patients and reduce stress for families by engaging them in patient care. This study developed and piloted a family-led coaching tool to support patients undergoing SATs/SBTs. METHODS: Patient and family member dyads were recruited from 2 medical-surgical ICUs in Calgary, Canada (February 3-August 1, 2023). Surveys were administered to collect family (1) demographics, (2) anxiety and satisfaction with ICU care, (3) feedback on the tool, and (4) attitudes about family presence during SATs/SBTs (also collected from clinicians). Tool feasibility was determined by calculating the proportions of (1) eligible patients who were recommended for participation in the study by clinicians and (2) families approached who consented to participate in the study. RESULTS: One thousand one hundred fifty patients were admitted to the study ICUs during the study period of which 819 received mechanical ventilation, and 42 were recommended by bedside clinicians for participation in the study. Twenty-five dyads were approached, 21 dyads consented to participate, and one withdrew consent before data collection. Of the enrolled families, 12 (60%) reported the coaching tool to be useful, and 5 (25%) recommended minor suggestions such as "shortening" the tool. Fourteen (70%) families reported positive experiences (through open-ended feedback) with being present for the SAT/SBT. State-Trait Anxiety Inventory (Y1) scores (scale range 20-80 points) significantly decreased in families from the first (pre coaching) to the second (post coaching) measures (mean decrease 8.2 points, SD 10.3, P = .001). All clinicians indicated they were comfortable with family presence and/or coaching during SATs/SBTs. CONCLUSION: Family-led coaching of patients during SATs/SBTs appears to be feasible, favorably perceived by families and clinicians, and potentially associated with lower family anxiety.

Evaluation of Dexmedetomidine Withdrawal and Management After Prolonged Infusion.

PURPOSE: Dexmedetomidine is often used for longer than its labeled indication of 24 hours, raising concerns for potential withdrawal. Data are limited regarding this syndrome in adult patients. This study aimed to further characterize dexmedetomidine withdrawal in critically ill adult patients after prolonged use. METHODS: This was an institutional review board-approved, single-center, retrospective chart review conducted at a tertiary academic medical center. Adult intensive care unit (ICU) patients on dexmedetomidine for ≥72 hours in 2019 were screened for inclusion. Exclusion criteria were interruption of dexmedetomidine for >6 hours, indications for dexmedetomidine other than sedation, or patients with neurological or burn injury. The major end point was the incidence of dexmedetomidine withdrawal, defined as meeting ≥2 of the following criteria within 24 hours of discontinuation: newly positive Confusion Assessment Method for ICU, Richmond Agitation Sedation Scale score of ≥+2, hypertension, and tachycardia. Minor end points were incidence of individual withdrawal signs as previously described, additional sedatives or antipsychotics required, dose and duration of dexmedetomidine infusion, length of ventilation, ICU and hospital length of stay, and new onset of the following: fever, vomiting, loose stools/diarrhea, diaphoresis, or seizure. FINDINGS: Of the 152 patients included, dexmedetomidine withdrawal occurred in 54 patients (35.5%). Rebound hypertension was the most common withdrawal sign (47 patients [87.0%]). In the withdrawal group, significantly more patients required additional ß-blockers (29 [53.7%] vs 10 [10.2%]; P < 0.01), were reinitiated on dexmedetomidine (16 [29.6%] vs 10 [10.2%]; P < 0.01), and required a start or increased dose of clonidine (6 [11.1%] vs 3 [3.1%]; P = 0.04). There was no significant difference in the cumulative dose or duration of dexmedetomidine between the groups. Length of ventilation was longer in the withdrawal group (171 hours [83.7-280.8 hours] vs 159 hours [149.0-335.7 hours]; P < 0.01), but there was no difference in ICU or hospital length of stay. IMPLICATIONS: Prolonged use of dexmedetomidine was associated with withdrawal syndrome in 35.5% of patients in our study. Larger trials are needed to confirm the risk factors for dexmedetomidine withdrawal and identify measures to prevent withdrawal.

Predictive model for the risk of paediatric intensive care utilization in children with medical complexity: A longitudinal retrospective cohort study.

BACKGROUND: Children with medical complexity (CMC) are at increased risk of admission in intensive care. Despite improvements in mortality rates, there remains a burden of morbidity, long-term health care needs and hospital readmissions. Beyond clinical factors, socio-demographic determinants could impact utilization of acute services. AIM: To identify risk factors that can differentiate CMC who are admitted to the paediatric intensive care unit (PICU). STUDY DESIGN: A 6-year longitudinal retrospective cohort study evaluated clinical, socio-demographic and health care utilization. RESULTS: A total of 248 CMC were included, with a median age of 13 years (9.75-17.00). Intensive care admission rate was 47.2%. The risk of PICU admission was higher for children undergoing surgical interventions (HR = 1.58, 95% CI 1.34-1.86, p < .001) and those using medical devices (HR = 1.81, 95% CI 1.54-2.13, p < .001). Mother's higher educational level was a protective factor (HR = 0.66, 95% CI 0.55-0.79, p < .001). Multivariable analysis revealed significant associations between risk of admission and the presence of malignancy, comorbidities, home medical devices, surgical procedures and higher health care utilization. Children's age and higher maternal educational level acted as protective factors. CONCLUSION: Socio-demographic factors should be considered in the provision of care to CMC. Individualized assessments to guide supportive interventions adapted to socio-economic factors may prevent PICU admissions. RELEVANCE TO CLINICAL PRACTICE: This study highlights the importance of integrating individualized assessments of socio-demographic risk factors, such as maternal educational level, into the clinical practice of paediatric nurses. Moreover, targeted interventions, including educational resources and community support programmes, may optimize care.

Parenteral nutrition customization in pediatrics: A descriptive cohort study.

OBJECTIVES: The main objective of this study was to analyze the reasons for customizing parenteral nutrition (PN) in pediatric patients admitted to a quaternary hospital. METHODS: We performed a descriptive cohort study on 264 hospitalized children receiving PN. Anthropometric, biochemical, and hospitalization data were collected from patient records. Unequivocal reasons for customizing PN were defined as situations precluding prescription of a standard adult/teenager PN and included renal and/or liver failure, energy-protein adequacy, and elevated mineral and triglyceride levels. RESULTS: A total of 264 patients, with a median age of 2.2 years (IQR: 0.3-9.0 years), comprising intensive care (n = 216; 81.8%) and malnourished (n = 91; 36.1%) patients, were evaluated. In the first 48 h, 87.9% (n = 232) of the sample required customized PN for energy-protein adequacy (210 of 232), maintained over subsequent days in most cases. Among patients requiring second individualization, mineral disturbance was the main reason observed, especially within the first 4 days of PN use (n = 21; 60%). Unequivocal reasons for customizing PN occurred in 97.4% (n = 226) of cases in the first 48 h; 96.2% (n = 177) of cases on the fourth day; and 90.1% (n = 92) of cases on the seventh day of PN use. An inverse correlation was found between weight/age z score and number of second individualizations (r = -0.222; P = 0.002). CONCLUSION: Customized PN proved essential, especially for younger, malnourished, and intensive care patients. Investment in training a Nutritional Multidisciplinary Therapy Team and acquiring a specific electronic system for prescribing PN is suggested.

Multitask learning to predict successful weaning in critically ill ventilated patients: A retrospective analysis of the MIMIC-IV database.

Objective: Weaning is an essential issue in critical care. This study explores the efficacy of multitask learning models in predicting successful weaning in critically ill ventilated patients using the Medical Information Mart for Intensive Care (MIMIC) IV database. Methods: We employed a multitask learning framework with a shared bottom network to facilitate common knowledge extraction across all tasks. We used the Shapley additive explanations (SHAP) plot and partial dependence plot (PDP) for model explainability. Furthermore, we conducted an error analysis to assess the strength and limitation of the model. Area under receiver operating characteristic curve (AUROC), calibration plot and decision curve analysis were used to determine the performance of the model. Results: A total of 7758 critically ill patients were included in the analyses, and 78.5% of them were successfully weaned. Multitask learning combined with spontaneous breath trial achieved a higher performance to predict successful weaning compared with multitask learning combined with shock and mortality (area under receiver operating characteristic curve, AUROC, 0.820 ± 0.002 vs 0.817 ± 0.001, p < 0.001). We assessed the performance of the model using calibration and decision curve analyses and further interpreted the model through SHAP and PDP plots. The error analysis identified a relatively high error rate among those with low disease severities, including low mean airway pressure and high enteral feeding. Conclusion: We demonstrated that multitask machine learning increased predictive accuracy for successful weaning through combining tasks with a high inter-task relationship. The model explainability and error analysis should enhance trust in the model.

Mortality Risk Stratification Utilizing Artificial Intelligence Electrocardiogram for Hyperkalemia in Cardiac Intensive Care Unit Patients.

Background: Hyperkalemia has been associated with increased mortality in cardiac intensive care unit (CICU) patients. An artificial intelligence (AI) enhanced electrocardiogram (ECG) can predict hyperkalemia, and other AI-ECG algorithms have demonstrated mortality risk-stratification in CICU patients. Objectives: The authors hypothesized that the AI-ECG hyperkalemia algorithm could stratify mortality risk beyond laboratory serum potassium measurement alone. Methods: We included 11,234 unique Mayo Clinic CICU patients admitted from 2007 to 2018 with a 12-lead ECG and blood potassium (K) level obtained at admission with K ≥5 mEq/L defining hyperkalemia. ECGs underwent AI evaluation for the probability of hyperkalemia (probability >0.5 defined as positive). Hospital mortality was analyzed using logistic regression, and survival to 1 year was estimated using Kaplan-Meier and Cox analysis. Results: In the final cohort (n = 11,234), the mean age was 69.6 ± 10.5 years, 37.8% were females, and 92.4% were White. Chronic kidney disease was present in 20.2%. The mean laboratory potassium value for the cohort was 4.2 ± 0.3 mEq/L. The AI-ECG predicted hyperkalemia in 33.9% (n = 3,810) of CICU patients and 12.9% (n = 1,451) of patients had laboratory-confirmed hyperkalemia (K ≥5 mEq/L). In-hospital mortality increased in false-positive, false-negative, and true-positive patients, respectively (P < 0.001), and each of these patient groups had successively lower survival out to 1 year. Conclusions: AI-ECG-based prediction of hyperkalemia, even with a normal laboratory potassium value, was associated with higher in-hospital mortality and lower 1-year survival in CICU patients. This study demonstrated that AI-ECG probability of hyperkalemia may enable rapid individualized risk stratification in critically ill patients beyond laboratory value alone.

Platelet aggregates in lung capillaries in severely decompensated pulmonary hypertension.

The mechanism of thrombocytopenia during acute pulmonary hypertension (PH) decompensation may be partly due to platelet aggregation in the lung. Platelet aggregates in explanted lung from 16 lung transplant patients during acute PH decompensation with and without thrombocytopenia were identified by immunohistochemistry. Scanning electron microscopy (SEM) was performed. 7 explant lung controls without PH and thrombocytopenia were also examined. Compared with controls, the median number of platelet aggregates was higher in patients with acute PH decompensation with thrombocytopenia (19.4 [IQR 3.4-38.3] vs 147.5 [IQR 26.5-203.2]). SEM showed capillaries filled with platelet aggregates. Our study suggests that platelets may aggregate in the lungs during acute PH decompensation.

Derivation and validation of generalized sepsis-induced acute respiratory failure phenotypes among critically ill patients: a retrospective study.

BACKGROUND: Septic patients who develop acute respiratory failure (ARF) requiring mechanical ventilation represent a heterogenous subgroup of critically ill patients with widely variable clinical characteristics. Identifying distinct phenotypes of these patients may reveal insights about the broader heterogeneity in the clinical course of sepsis, considering multi-organ dynamics. We aimed to derive novel phenotypes of sepsis-induced ARF using observational clinical data and investigate the generalizability of the derived phenotypes. METHODS: We performed a multi-center retrospective study of ICU patients with sepsis who required mechanical ventilation for ≥ 24 h. Data from two different high-volume academic hospital centers were used, where all phenotypes were derived in MICU of Hospital-I (N = 3225). The derived phenotypes were validated in MICU of Hospital-II (N = 848), SICU of Hospital-I (N = 1112), and SICU of Hospital-II (N = 465). Clinical data from 24 h preceding intubation was used to derive distinct phenotypes using an explainable machine learning-based clustering model interpreted by clinical experts. RESULTS: Four distinct ARF phenotypes were identified: A (severe multi-organ dysfunction (MOD) with a high likelihood of kidney injury and heart failure), B (severe hypoxemic respiratory failure [median P/F = 123]), C (mild hypoxia [median P/F = 240]), and D (severe MOD with a high likelihood of hepatic injury, coagulopathy, and lactic acidosis). Patients in each phenotype showed differences in clinical course and mortality rates despite similarities in demographics and admission co-morbidities. The phenotypes were reproduced in external validation utilizing the MICU of Hospital-II and SICUs from Hospital-I and -II. Kaplan-Meier analysis showed significant difference in 28-day mortality across the phenotypes (p < 0.01) and consistent across MICU and SICU of both Hospital-I and -II. The phenotypes demonstrated differences in treatment effects associated with high positive end-expiratory pressure (PEEP) strategy. CONCLUSION: The phenotypes demonstrated unique patterns of organ injury and differences in clinical outcomes, which may help inform future research and clinical trial design for tailored management strategies.

Central versus peripheral VA ECMO for cardiogenic shock: an 8-year experience of a tertiary cardiac surgery center in Greece.

BACKGROUND: VA ECMO has emerged as an effective rescue therapy in patients with cardiogenic shock refractory to standard treatment protocols and its use is rising worldwide in the last decade. Although experience and availability are growing, outcomes remain poor. There is need for evidence to ameliorate clinical practice and improve outcomes. METHODS: We retrospectively reviewed the medical records of all patients who were supported with VA ECMO for cardiogenic shock at our institution between January 2015 and January 2023. The study purpose was to compare outcomes between patients who were supported with central versus peripheral configuration. RESULTS: ECMO was applied in 108 patients of whom central configuration in 48 (44%) and peripheral in 60 (56%). Patients supported with central VA ECMO were more likely to be supported for post cardiotomy shock [OR 4.6 (CI 95% 2.03 - 10.41)], while patients in the peripheral group for chronic heart failure decompensation [OR 9.4 (CI 95% 1.16 - 76.3]. Central VA ECMO had worse survival during ECMO support (29.2% vs 51.7%, p=0.018) and at discharge (8% vs 37%, p=0.001). These patients were at high risk of complications, such as acute kidney injury (AKI), [OR 2.37 (CI 95% 1.06 - 5.3), p = 0.034] and major bleeding [OR 3.08 (CI 95% 1.36 - 6.94), p<0.001]. CONCLUSIONS: Patients on central VA ECMO were supported mainly for post cardiotomy shock, presented with more complications such as major bleeding and AKI and had worse survival to hospital discharge, compared with patients on peripheral VA ECMO. Patient selection, timing of implementation, cannulation strategy and configuration remain main determinants of clinical outcome.

Impact of rapid response system in mortality and complications post-orthopedic surgery: a retrospective cohort study.

BACKGROUND: Rapid response systems (RRSs) are used in hospitals to identify and treat deteriorating patients. However, RRS implementation and outcomes in orthopedic and surgical patients remain controversial. We aimed to investigate whether the RRS affects mortality and complications after orthopedic surgery. METHODS: The National Health Insurance Service of South Korea provided the data for this population-based cohort study. Individuals who were admitted to the hospital that implemented RRS were categorized into the RRS group and those admitted to a hospital that did not implement the RRS were categorized into the non-RRS group. In-hospital mortality and postoperative complications were the endpoints. RESULTS: A total of 931,774 adult patients were included. Among them, 93,293 patients underwent orthopedic surgery in a hospital that implemented RRS and were assigned to the RRS group, whereas 838,481 patients were assigned to the non-RRS group. In multivariable logistic regression analysis, the RRS group was not associated with in-hospital mortality after orthopedic surgery compared with the non-RRS group (odds ratio [OR] 0.93, 95% confidence interval [CI] 0.80, 1.08; P = 0.350). However, the RRS group was associated with a 14% lower postoperative complication rate after orthopedic surgery than the non-RRS group (OR 0.86, 95% CI 0.84, 0.86; P < 0.001). CONCLUSIONS: The RRS was not associated with in-hospital mortality following orthopedic surgery in South Korea. However, RRS deployment was related to a decreased risk of postoperative complications in patients undergoing orthopedic surgery.

Pulmonary Shunt in Critical Care: A Comprehensive Review of Pathophysiology, Diagnosis, and Management Strategies.

Pulmonary shunt, an abnormal passage of blood through the pulmonary circulation without adequate gas exchange, poses significant challenges in critical care. This comprehensive review explores the pathophysiology, diagnostic approaches, and management strategies associated with pulmonary shunt. Pulmonary shunts are classified into anatomical and physiological types, each with distinct mechanisms and implications for gas exchange. Anatomical shunts result from structural heart defects, while physiological shunts arise from ventilation-perfusion (V/Q) mismatches. Both conditions can significantly impair oxygenation and contribute to multi-organ dysfunction. This review delves into various diagnostic modalities, including clinical assessment, imaging techniques such as chest X-ray and CT scans, and advanced diagnostic methods such as V/Q scanning and echocardiography. Challenges in diagnosing pulmonary shunt are discussed, emphasizing the limitations of current tools and the need for accurate differentiation of shunt types. Management strategies are examined, covering pharmacological interventions, non-pharmacological treatments such as mechanical ventilation and prone positioning, and surgical options. Emerging therapies and innovations in treatment are also highlighted. Special considerations are given to different patient populations, including pediatric and elderly patients and those with multiple comorbidities. This review concludes with an analysis of the prognosis and outcomes associated with pulmonary shunt, focusing on short-term and long-term impacts on survival and quality of life. This review aims to enhance understanding and guide effective management practices for pulmonary shunt in critical care settings by synthesizing current knowledge and identifying areas for further research.

Improving Outcomes for ICU Family Members: The Role of Spiritual Care.

Having a family member hospitalized in the intensive care unit (ICU) can be a stressful experience for family members, encompassing both psychological and spiritual distress. With over 5 million ICU admissions annually in the United States, it is imperative to enhance the experiences and coping mechanisms of ICU family members. In particularly challenging situations, some family members even face psychological effects known as post-intensive care syndrome-family, which includes anxiety, depression, and posttraumatic stress. The distress may be worsened when patients and families experience poor communication or medical care, which has been shown to be more common among minoritized populations including Black and Hispanic patients and families. Family members' emotional and spiritual distress also has an effect on the medical decisions they make for the patient. While research has delved into the impact of spiritual care for ICU family members, further investigation is still needed to determine the most effective approaches for delivering such care. This narrative review will describe a conceptual model aimed at guiding future research in this endeavor. The model proposes that chaplains provide emotional, spiritual, and information support to ICU family members. This affects both their ICU experience, decision making, and outcomes for the patient and family. This process is also affected by characteristics of the family such as race, ethnicity, and economic status. This model helps identify gaps in research, including the need for randomized trials of spiritual care that identify mechanisms underlying outcomes and demonstrate impact of spiritual care, and consider race, ethnicity, and other characteristics.

Patient Safety Incident Reporting and Learning Guidelines Implemented by Health Care Professionals in Specialized Care Units: Scoping Review.

BACKGROUND: Implementing Patient Safety Incident Reporting and Learning (PSIRL) guidelines is critical in guiding clinical practice and improving clinical outcomes in specialized care units (SCUs). There is limited research on the evidence of the implemented PSIRL guidelines in SCUs at the global level. OBJECTIVE: This review aims to map the evidence of PSIRL guidelines implemented by health care professionals in specialized care units globally. METHODS: A scoping review methodology, according to Joanna Briggs Institute, was adopted. The eligibility criteria were guided by the Population, Concept, and Context (PCC) framework, with the Population including health care professionals, the Concept including PSIRL guidelines, and the Context including specialized units globally. Papers written in English were searched from relevant databases and search engines. The PRISMA-ScR (Preferred Reporting Items for Scoping Reviews and Meta-Analyses extension for Scoping Reviews) checklist for used. RESULTS: The 13 selected studies were published from 2003 to 2023. Most articles are from the Netherlands and Switzerland (n=3), followed by South Africa (n=2). The nature of implemented PSIRL guidelines was computer-based (n=11) and paper-based incident reporting (n=2). The reporting system was intended for all the health care professionals within the specialized units, focusing on patients, staff members, and families. The outcomes of implemented incident reporting guidelines were positive, as evidenced by improved reporting of incidents, including medication errors (n=8) and decreased rate of incidents and errors (n=4). Furthermore, 1 study showed no change (n=1) in implementing the incident reporting guidelines. CONCLUSIONS: The implementation of reporting of patient safety incidents (PSIs) in specialized units started to be reported around 2002; however, the frequency of yearly publications remains very low. Although some specialized units are still using multifaceted interventions and paper reporting systems in reporting PSIs, the implementation of electronic and computer-based reporting systems is gaining momentum. The effective implementation of an electronic-based reporting system should extend into other units beyond critical care units, as it increases the reporting of PSIs, reducing time to make an informed reporting of PSIs and immediate accessibility to information when needed for analysis. The evidence on the implementation of PSI reporting guidelines in SCUs comes from 5 different continents (Asia, Africa, Australia, Europe, and North America). However, the number identified for certain countries within each continent is very minimal.

Establishment of seven lung ultrasound phenotypes: a retrospective observational study of an LUS registry.

BACKGROUND: Lung phenotypes have been extensively utilized to assess lung injury and guide precise treatment. However, current phenotypic evaluation methods rely on CT scans and other techniques. Although lung ultrasound (LUS) is widely employed in critically ill patients, there is a lack of comprehensive and systematic identification of LUS phenotypes based on clinical data and assessment of their clinical value. METHODS: Our study was based on a retrospective database. A total of 821 patients were included from September 2019 to October 2020. 1902 LUS examinations were performed in this period. Using a dataset of 55 LUS examinations focused on lung injuries, a group of experts developed an algorithm for classifying LUS phenotypes based on clinical practice, expert experience, and lecture review. This algorithm underwent validation and refinement with an additional 140 LUS images, leading to five iterative revisions and the generation of 1902 distinct LUS phenotypes. Subsequently, a validated machine learning algorithm was applied to these phenotypes. To assess the algorithm's effectiveness, experts manually verified 30% of the phenotypes, confirming its efficacy. Using K-means cluster analysis and expert image selection from the 1902 LUS examinations, we established seven distinct LUS phenotypes. To further explore the diagnostic value of these phenotypes for clinical diagnosis, we investigated their auxiliary diagnostic capabilities. RESULTS: A total of 1902 LUS phenotypes were tested by randomly selecting 30% to verify the phenotypic accuracy. With the 1902 LUS phenotypes, seven lung ultrasound phenotypes were established through statistical K-means cluster analysis and expert screening. The acute respiratory distress syndrome (ARDS) exhibited gravity-dependent phenotypes, while the cardiogenic pulmonary edema exhibited nongravity phenotypes. The baseline characteristics of the 821 patients included age (66.14 ± 11.76), sex (560/321), heart rate (96.99 ± 23.75), mean arterial pressure (86.5 ± 13.57), Acute Physiology and Chronic Health Evaluation II (APACHE II)score (20.49 ± 8.60), and duration of ICU stay (24.50 ± 26.22); among the 821 patients, 78.8% were cured. In severe pneumonia patients, the gravity-dependent phenotype accounted for 42% of the cases, whereas the nongravity-dependent phenotype constituted 58%. These findings highlight the value of applying different LUS phenotypes in various diagnoses. CONCLUSIONS: Seven sets of LUS phenotypes were established through machine learning analysis of retrospective data; these phenotypes could represent the typical characteristics of patients with different types of critical illness.
