Effectiveness of Nirsevimab Immunoprophylaxis Against Respiratory Syncytial Virus-related Outcomes in Hospital Care Settings: A Seasonal Cohort Study of Infants in Catalonia (Spain).

In Catalonia, infants <6 months old were eligible to receive nirsevimab, a novel monoclonal antibody against respiratory syncytial virus (RSV). We aimed to analyze nirsevimab's effectiveness in hospital-related outcomes of the seasonal cohort (born during the RSV epidemic from October to January 2024) and compared them with the catch-up cohort (born from April to September 2023). Retrospective cohort study of all infants born between October 1, 2023, and January 21, 2024, according to their immunization with nirsevimab (immunized and nonimmunized). We followed individuals until the earliest of an outcome-hospital emergency visits, hospital admission or pediatric intensive care unit (PICU) admission due to RSV-associated or all-causes bronchiolitis-death or the end of the study. We used the Kaplan-Meier estimator and fitted Cox regression models using a calendar time scale to estimate hazard ratios (HRs) and their 95% confidence interval (CI). Sensitivity analysis was performed through matching. Among 15,341 infants, a dose of nirsevimab led to an adjusted HR for hospital admission, PICU admission and emergency visits due to RSV bronchiolitis of 0.26 (95% CI: 0.17-0.39), 0.15 (95% CI: 0.07-0.28) and 0.46 (95% CI: 0.23-0.90), respectively. For all-causes bronchiolitis, the former adjusted HRs were 0.45 (95% CI: 0.31-0.63), 0.23 (95% CI: 0.13-0.41) and 0.49 (95% CI: 0.35-0.68), respectively. Nirsevimab was associated with reductions of 74% and 85% hospitalizations and PICU admissions regarding RSV-associated bronchiolitis, respectively. These percentages are slightly lower than those for the catch-up cohort. This information may help the implementation of RSV-immunization campaigns by public health authorities.

Nasal microbiota predictors for methicillin resistant Staphylococcus colonization in critically ill children.

Surveillance cultures to identify patients colonized with methicillin-resistant Staphylococcus aureus (MRSA) is recommended at pediatric intensive care unit (PICU) admission but doesn't capture other methicillin-resistant Staphylococcus and is resource intensive. We determined the prevalence and identified nasal microbiome predictors for methicillin-resistant Staphylococcus colonization at the time of PICU admission. A prospective cohort study was performed in a 20-bed pediatric intensive care unit (PICU) between 2020-2021. Anterior nares nasal swabs processed for MRSA culture, nasal microbiome and mecA+ qPCR were obtained within first five days after PICU admission. Predictive values of methicillin-resistant Staphylococcus carriage on symptoms of infection and for nasal microbiome attributes were calculated. A total of 5 (8.0%) of 62 patients had a nares culture positive for MRSA and 22 (35.5%) of 63 patients had methicillin-resistant Staphylococcus (MRSA or methicillin-resistant coagulase-negative Staphylococci). In univariate analysis, carriage with MRSA or MRCoNS was associated with having a fever during PICU stay. Colonization with a distinct set of microbes (including Haemophilus, Streptococcus, Prevotella and Corynebacterium sp.) was predictive of having methicillin-resistant Staphylococcus colonization. Carriage with methicillin-resistant Staphylococcus may lead to transmission in critically ill pediatric patients. Carriage of particular nasal microbes appears to facilitate colonization with methicillin-resistant Staphylococcus.

The Incidence and Outcomes of Acute Kidney Disease in Critically Ill Children.

Acute kidney disease (AKD) includes abnormalities of kidney function present for <90 days. Acute kidney injury (AKI) is defined as a subset of AKD, with onset within seven days. There is scant data on the rates of AKD in children and its association with outcomes. Our primary objective was to examine the rates of AKD with and without AKI and compare major adverse events (MAKE) in children in the pediatric intensive care unit (PICU). This is a retrospective cohort study of patients ≤18 years old who were admitted to a quaternary care PICU between 2009 and 2016 using the high-density pediatric database. All patients included in the primary analysis had a known baseline serum creatinine. Patients who had a baseline estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m2 or a history of dialysis dependence or kidney transplant were excluded. AKI and AKD were defined by Kidney Disease: Improving Global Outcomes definitions. MAKE-90 was defined as a composite outcome of death, dialysis, or persistent kidney dysfunction 90 days after PICU admission. Among 5,922 children included in this study, 1,199 (20.2%) had AKD, of which 1,092 (91%) had AKD with AKI and 107 (8.9%) had AKD without AKI. MAKE-90 occurred in 26% (308/1,199) of those with AKD compared to 3.6% (172/4723) without (p=<0.001). MAKE-90 occurred in 26% (279/1,092) of AKD with AKI and 27% (29/107) of AKD without AKI. After adjusting for age, sex, and illness severity, compared to patients that had no AKD, patients with AKD with AKI (aOR: 14.39, 95% CI: 11.06-18.72) and patients with AKD without AKI (aOR: 7.83, 95% CI: 4.54-13.51) had a greater odds of MAKE-90. More than a quarter of pediatric critically ill patients with AKD develop MAKE-90. Even in the absence of AKI, AKD is an independent risk factor for MAKE-90.

PROGNOSTIC ACCURACY OF MACHINE LEARNING MODELS FOR IN-HOSPITAL MORTALITY AMONG CHILDREN WITH PHOENIX SEPSIS ADMITTED TO THE PEDIATRIC INTENSIVE CARE UNIT.

Objective: The Phoenix sepsis criteria define sepsis in children with suspected or confirmed infection who have ≥2 in the Phoenix Sepsis Score. The adoption of the Phoenix sepsis criteria eliminated the Systemic Inflammatory Response Syndrome criteria from the definition of pediatric sepsis. The objective of this study is to derive and validate machine learning models predicting in-hospital mortality for children with suspected or confirmed infection or who met the Phoenix sepsis criteria for sepsis and septic shock. Materials and Methods: Retrospective cohort analysis of 63,824 patients with suspected or confirmed infection admission diagnosis in two pediatric intensive care units (PICUs) in Atlanta, Georgia, from January 1, 2010, through May 10, 2022. The Phoenix Sepsis Score criteria were applied to data collected within 24 h of PICU admission. The primary outcome was in-hospital mortality. The composite secondary outcome was in-hospital mortality or PICU length of stay (LOS) ≥ 72 h. Model-based score performance measures were the area under the precision-recall curve (AUPRC) and the area under the receiver operating characteristic curve (AUROC). Results: Among 18,389/63,824 (29%) children with suspected infection (median age [25th - 75th interquartile range [IQR]): 3.9 [1.1,10.9]; female, 45%, a total of 5,355 met Phoenix sepsis criteria within 24 h of PICU admission. Of the children with Phoenix sepsis, a total of 514 (9.6%) died in the hospital, and 2,848 (53.2%) died or had a PICU stay of ≥72 h. Children with Phoenix septic shock had an in-hospital mortality of 386 (16.4%) and 1,294 (54.9%) had in-hospital mortality or PICU stay of ≥72 h. For children with Phoenix sepsis and Phoenix septic shock, the multivariable logistic regression, light gradient boosting machine, random forest, eXtreme Gradient Boosting, support vector machine, multilayer perceptron, and decision tree models predicting in-hospital mortality had AUPRCs of 0.48-0.65 (95% CI range: 0.42-0.66), 0.50-0.70 (95% CI range: 0.44-0.70), 0.52-0.70 (95% CI range: 0.47-0.71), 0.50-0.70 (95% CI range: 0.44-0.70), 0.49-0.67 (95% CI range: 0.43-0.68), 0.49-0.66 (95% CI range: 0.45-0.67), and 0.30-0.38 (95% CI range: 0.28-0.40) and AUROCs of 0.82-0.88 (95% CI range: 0.82-0.90), 0.84-0.88 (95% CI range: 0.84-0.90), 0.81-0.88 (95% CI range: 0.81-0.90), 0.84-0.88 (95% CI range: 0.83-0.90), 0.82-0.87 (95% CI range: 0.82-0.90), 0.80-0.86 (95% CI range: 0.79-0.89), and 0.76-0.82 (95% CI range: 0.75-0.85), respectively. Conclusion: Among children with Phoenix sepsis admitted to a PICU, the random forest model had the best AUPRC for in-hospital mortality compared to the light gradient boosting machine, eXtreme Gradient Boosting, logistic regression, multilayer perceptron, support vector machine, and decision tree models or a Phoenix Sepsis Score ≥ 2. These findings suggest that machine learning methods to predict in-hospital mortality in children with suspected infection predict mortality in a PICU setting with more accuracy than application of the Phoenix sepsis criteria.

Factors affecting intensive care length of stay in critically ill pediatric patients with burn injuries.

Burns in children are often complex injuries, leading to prolonged length of stay (LOS) and significant morbidity. LOS in pediatric intensive care units (PICUs) is a key measure for evaluating illness severity, clinical outcomes, and quality of care. Accurate prediction of LOS is vital for improving care planning and resource allocation. There is limited data for predicting LOS in severely burned children in PICU. This study aims to identify significant factors associated with prolonged PICU stays and offer a simple LOS-predicting model. This historical cohort study included all patients < 18years, admitted for severe burn injuries to Israel's largest tertiary hospital PICU, from 2015 to 2020. Statistical analyses were conducted to identify factors linked to prolonged LOS and a predictive model was designed. The study included 39 pediatric burn patients and identified several factors associated with longer PICU stays. Patients with LOS of ˃7days (i.e.-"long LOS") had significantly higher %TBSA (33.11 ± 17.87% vs. 16.67 ± 7.98%, p < 0.001. During the first 24 and 48h, the "long LOS" group had lower minimal systolic blood pressure (SBP) (70.67 ± 17.49mmHg vs. 84.38 ± 16.73mmHg, p = 0.015 and 69.39mmHg ± 16.44 vs. 81.10mmHg ± 19.67, p = 0.018). Although serum lactate levels were higher in the "long LOS" group, the difference was not significant, and platelet counts in this group were significantly lower during the first 48h (184K/µL vs. 264.5K/µL, p = 0.003). A predictive model based on %TBSA, SBP, lactate, and platelet count was developed, demonstrating 100% specificity and positive predictive value for predicting LOS over 7days in severely burned children. Key clinical indicators at PICU admission in severely burned children were associated with LOS > 7days. The resulting predictive model, although requiring further validation in multi-site studies, offers a promising tool for enhancing care planning in this population.

Association between serum albumin levels at admission and clinical outcomes in pediatric intensive care units: a multi-center study

BackgroundAlbumin, a vital component in regulating human blood oncotic pressure, plays an important role in the prediction of prognosis in pediatric patients.Previous research identified significant differences in serum albumin levels of healthy and critically ill children.MethodsThe present study aims to investigate the correlation between albumin levels measured during pediatric intensive care unit(PICU) admission and clinical outcomes. In 2022, a comprehensive analysis of the records was conducted retrospectively in four tertiary hospital PICUs in different cities in the south-east region of Turkey. We then conducted a ROC analysis to predict mortality based on hypoalbuminemia.A cut-off value was determined, and the patients were divided into two groups: hypoalbuminemic and normoalbuminemic.Based on this cut-off level, we evaluated the association between admission serum albumin levels and mortality, length of stay, laboratories, need for mechanical ventilation, and extracorporeal treatments.ResultsA total of 1329 patients admitted to the PICUs between January 1, 2022 and January 1, 2023 were included. The mortality rate amounted to 16.2%.The mean albumin level was 4.03 ± 0.69 g/dl in the surviving and 3.35 ± 0.90 g/dl in the non-surviving group(p < 0.001).The average length of stay in the PICU amounted to 8.98 ± 17.07, while the mean length of hospital stay was 11.23 ± 18.81days.Patients with hypoalbuminemia had significantly longer stays in the PICU and hospital as compared to those with normal albumin levels(p = 0.025 and p < 0.001,respectively).We found robust evidence that albumin levels are a strong predictor of mortality, with a predictive rate of 84.5%(OR:0.322, 95% CI:0.263–0.395, p < 0.001).The cut-off value was 3.785(AUC:0.731, Sensitivity:68.3%, Specificity:67%). A negative correlation was identified between albumin levels and lactate, C- reactive protein (CRP), and Blood urea nitrogen (BUN) levels across all patients. Conversely, a positive correlation was observed between neutrophil, lymphocyte, platelet, hemoglobin, sodium, and glucose levels. However, in patients with a cut-off point of 3.785 for albumin levels, a negative correlation was observed between albumin and lactate, CRP, and creatine levels. Conversely, a positive correlation was found between bicarbonate, platelet, hemoglobin, and glucose levels. Based on these findings, we conclude that hypoalbuminemia is associated with a higher rate of inotrope therapy and mechanical ventilation support. Furthermore, the rates of plasmapheresis, continuous renal replacement therapy, and extracorporeal membrane oxygenation initiation were markedly reduced in patients with elevated albumin levels (p < 0.001).ConclusionThe serum albumin, which is an excellent and cost-effective biomarker that can be readily and economically evaluated in any center worldwide, as evidenced by the findings of our study, is a highly efficacious indicator of admission albumin levels for the prediction of mortality and outcomes in PICUs. Furthermore, it predicts the selection of appropriate treatment and mechanical supports. It is straightforward to utilise, as it does not necessitate the use of scoring systems or tests that require lengthy and intricate analyses, and it is readily available.

Predicting the risk of mortality in children with dengue-induced hepatitis admitted to the paediatric intensive care unit.

Dengue-associated acute liver failure (PALF) accounts for a high mortality rate in children admitted to the pediatric intensive care unit (PICU). To date, there is a lack of data on clinical algorithms for estimating the risk of mortality in pediatric patients with dengue-induced severe hepatitis (DISH). To determine the prevalence of PALF and identify the predictors of mortality among patients with DISH. This single-institution retrospective study was performed at a tertiary pediatric hospital in Vietnam between 2013 and 2022. The primary outcome was in-hospital mortality in pediatric patients with DISH, which was defined as either aspartate aminotransferase > 350 IU/L or alanine aminotransferase > 400 IU/L. Prognostic models for estimating the risk of death among patients with DISH were developed using a predefined set of clinical covariables and hepatic biomarkers on PICU admission and during the first 72 hours of admission. Area under the curve, multivariable logistic regression, and multiple imputation using the chained equation for missing values were performed. Backward stepwise model selection based on the Akaike information criterion was employed. Bootstrapping, calibration slope, and Brier score were used to assess the final models. A total of 459 children with DISH were included in the analysis. The median patient age was 7.7 years (interquartile range: 4.3-10.1 years). The prevalence of dengue-associated PALF in children with DISH was 18.3%. Thirty-nine DISH patients developing PALF (8.5%) died. Hepatic biomarkers, including the international normalized ratio (INR) ≥ 2.11 and total serum bilirubin (≥ 1.7 mg/dL), showed high predictive values for mortality (all P values < 0.001). Multivariable models showed the significant clinical predictors of death from dengue-induced PALF in patients with DISH, including reduced level of consciousness (pain and unresponsive levels on the Alert, Verbal, Pain, Unresponsive scale), high vasoactive-inotropic score (> 30), and elevated levels of blood lactate, INR, and serum bilirubin. The final prognostic model demonstrated high discrimination, Brier score, and an acceptable calibration slope. The prevalence of PALF in children with DISH is 18.3%. We developed robust prognostic models to estimate the risk of death in hospitalized children with severe dengue-induced hepatitis.

Sepsis Epidemiology and Outcomes in Pediatric Intensive Care Unit of Alkhadra Hospital, Tripoli, Libya

Despite the various interventions and therapies that have been implemented to improve the quality of life for children with sepsis, the prevalence and death rates continue to increase. This issue is a major public health problem that requires the continuous improvement of the guidelines and the identification of new strategies. The aim of the study was to identify the prevalence and outcomes of severe sepsis among children admitted to the Pediatric Intensive Care Unit (PICU). This study was conducted in PICU of Alkhadra Hospital in 2023 as a hospital-based retrospective study. All children who were admitted to the PICU from 2017 to 2022 were included. Data was collected from hospital file records, which included the following: age of patient, gender, comorbidities of patients, and source of admission; origin of sepsis; type of PICU admission; primary site of infection; organ dysfunction present at screening; and patient outcomes. Of the 1284 total admissions to the PICU, 128 patients (9.96%) met the definition of sepsis. Most patients (78.9%) were less than 6 years old. Respiratory problems and congenital malformations were the most common co-morbidities, with reported rates of 18.8% and 10.2%, respectively. The emergency department was the most common source of admission (67.2%). Nearly all patients had good overall performance, whereas (21.1%) of the patients were in a coma. 77.3% discharged during the study, and 22.7% died. Although decreasing the incidence through preventive measures is ideal, early recognition and treatment of sepsis will decrease both short- and long-term complications and related mortality of at-risk infants and children.

Bloodstream Infection in Children Managed at a Tertiary Hospital in Oman.

This study aimed to assess the local epidemiology and outcome of bloodstream infection (BSI) among Omani children. This retrospective study was conducted at Sultan Qaboos University Hospital, Muscat, Oman, over 5 years (2014-2018) and included laboratory-confirmed BSI among children aged 0-12 years old. Patients' demographic, clinical and laboratory data were extracted from the hospital's electronic records and used to assess BSI rates and outcomes. A total of 1,253 positive blood cultures were identified, of which 592 (47.2%) were regarded as contaminants. Overall, 404 (32.2%) significant episodes of BSI were identified in 272 patients; 346 (85.6%) significant episodes were in children aged ≤5 years and 366 (90.6%) had comorbidities. The 5-year incidence of BSI was 13 per 1,000 admissions. Furthermore, 333 (82.4%) episodes were healthcare-related infections. Enterobacterales (n = 152; 37.6%) were the most common organisms identified followed by coagulase-negative staphylococci (n = 63; 15.6%). Approximately 40% of Gram-negative organisms were resistant to third-generation cephalosporins. The crude mortality rate at 30 days was 9.2%. Paediatric intensive care unit admission (crude odds ratio [COR] = 2.24, 95% confidence interval [CI]: 0.98-4.78) and the presence of graft-versus-host disease (COR = 7.99, 95% CI: 1.52-37.76) were associated with increased death within 30 days. The multivariate logistic regression analysis showed that Pseudomonas aeruginosa (adjusted odds ratio = 18.46, 95% CI: 3.96-97.84) was the only independent predictor of increasing 30-day mortality in this cohort. A high rate of hospital-related BSI was found in children in Oman, highlighting the need to optimise infection control strategies and the care of central vein access devices.

Kidney and blood pressure outcomes 11years after pediatric critical illness and longitudinal impact of AKI: a prospective cohort study.

Acute kidney injury (AKI) is common in critically ill children and associated with adverse short-term outcomes; however, long-term outcomes are not well described. This longitudinal prospective cohort study examined the prevalence of chronic kidney disease (CKD) and hypertension (HTN) 11 vs. 6years after pediatric intensive care unit (PICU) admission and association with AKI. We examined children (age < 19years) without pre-existing kidney disease 11 ± 1.5years after PICU admission at a single center. AKI was defined using serum creatinine criteria. The primary outcome was a composite of CKD or HTN. CKD was defined as estimated glomerular filtration rate (eGFR) < 90mL/min/1.73 m2 or albuminuria. Multivariable analyses compared outcomes at 11- vs. 6-year follow-up and association with AKI during PICU admission. Of 96 children evaluated 11years after PICU admission, 16% had evidence of CKD or HTN (vs. 28% at 6years, p < 0.05). Multivariable analysis did not show improvement in outcomes from 6- to 11-year follow-up. eGFR decreased from 6- to 11-year follow-up (adjusted coefficient - 11.7, 95% CI - 17.6 to - 5.9) and systolic and diastolic blood pressures improved. AKI was associated with composite outcome at 6-year (adjusted odds ratio (aOR) 12.7, 95% CI 3.2-51.2, p < 0.001), but not 11-year follow-up (p = 0.31). AKI was associated with CKD (aOR 10.4, 95% CI 3.1-34.7) at 11years. This study provides novel data showing that adverse kidney and blood pressure outcomes remain highly prevalent 10years after critical illness in childhood. The association with AKI wanes over time.

Evaluation of children with acute central nervous system infections admitted to the pediatric intensive care unit and pediatric ward: a retrospective study

ObjectivesAcute central nervous system (CNS) infections in children can lead to neurological complications and mortality. This study aimed to identify the clinical manifestations, laboratory parameters, and cerebrospinal fluid characteristics indicative of CNS infections and define the risk factors that lead to pediatric intensive care unit (PICU) admission in the pediatric population of Şanlıurfa, a city in southeastern Turkey.MethodsThis retrospective analysis included patients aged 1 month to 18 years who were treated for acute CNS infections in the Şanlıurfa Training and Research Hospital between January 2020 and May 2023. Clinical data were obtained from the hospital electronic medical records.ResultsA total of 68 patients with acute CNS infections were included in this study. The median patient age was 3 (0.94–8.75) years. Fever was the most prevalent symptom in 92.6% of the patients. Of the total, 25% (n = 17) of the patients had an identified causative agent and 35.3% (n = 24) were admitted to the PICU. Serum C-reactive protein (CRP) levels were significantly higher in patients with bacterial meningitis than in those with viral meningitis (p = 0.007). Patients with impaired consciousness and seizure were significantly more likely to require admission to the PICU than patients without these conditions (both p < 0.001). Patients requiring PICU admission had significantly higher platelet counts (p = 0.01).ConclusionsImpaired consciousness, seizure, and thrombocytosis on admission were important risk factors for PICU admission. Serum CRP levels can serve as an indicator of bacterial meningitis. A combination of physical findings from clinical evaluations and laboratory data is necessary to accurately diagnose bacterial CNS infections.

Outcomes within 100 days of hematopoietic cell transplantation in pediatric patients: insights from an intensive care unit in Colombia.

Hematopoietic cell transplantation (HCT) has become an essential therapeutic modality for pediatric patients with malignant and non-malignant conditions. Despite its effectiveness, many patients experience post-transplant complications often leading into life-threatening conditions requiring specialized care in a Pediatric Intensive Care Unit (PICU). This study aims to describe clinical characteristics associated with mortality in pediatric HCT patients who needed PICU care within 100 days post-transplant in a resource-limited country. A retrospective cohort study was conducted involving pediatric HCT patients (<18 years old) admitted to our PICU from January 2012 to December 2021. Variables were characterized according to their nature, employing appropriate measures of central tendency and dispersion. The relationship between mortality and patient clinical characteristics was assessed using the Chi-square test or the Mann-Whitney U test, as applicable. A p-value of <0.05 was considered statistically significant. A Kaplan Meier survival curve was performed considering the days from HCT to death during PICU admission and a Cox regression analysis was conducted to analyze the association between PRISM III score and risk of death. Data analysis was executed utilizing the STATA SE v18 statistical software package. Of 316 HCTs, 69 patients required admission to the PICU. Haploidentical transplants from related donors were performed in 72.5% of these patients. The primary cause of PICU admission was infection, accounting for 68.1% (n = 47) of cases. Factors significantly associated with mortality included a PRISM III score > 20 (p < 0.002), mechanical ventilation (p < 0.007), renal replacement therapy (p < 0.002) and vasoactive support (p < 0.001). A total of 27 patients succumbed during their PICU stay. Kaplan Meier curve showed a survival rate of 51.6% at100-days post-transplant. A PRISM III score higher than 20 points was related with mortality (Hazard ratio 5.71 CI 95% 2.09-15.5). This study examines critical factors associated with mortality in pediatric HCT recipients who required admission to our PICU within the first 100 days post-transplant. Our findings indicate that infectious complications, alongside the need for advanced cardiovascular, respiratory, and renal support are strongly correlated with mortality. These results underscore the importance of early risk factor identification and targeted interventions to optimize patient outcomes.

Timing of Neonatal Discharge and Unplanned Readmission to PICUs Among Infants Born Preterm

Children born very preterm (<32 weeks) are at risk of ongoing morbidity and admission to pediatric intensive care units (PICUs) in childhood. However, the influence of the timing of neonatal discharge on unplanned PICU admission has not been established. To examine whether the timing of neonatal discharge (postmenstrual age and season) is associated with subsequent unplanned PICU admission. This retrospective cohort study used linked national data from the National Neonatal Research Database and Paediatric Intensive Care Audit Network (PICANet) for children born from January 2013 to December 2018 at 22 to 31 weeks' gestational age who were admitted to a neonatal unit in England and Wales and were discharged home at 34 weeks' postmenstrual age or later. All National Health Service (NHS) neonatal units and PICUs in England and Wales were included. Children were followed up until 2 years of chronological age. Data analysis was conducted from October 2023 to August 2024. Timing of discharge. The primary outcome was unplanned PICU admission between neonatal discharge and chronological age 2 years to any PICU within England and Wales. Survival analysis using a flexible parametric model was conducted with season of discharge (time-dependent factor), gestation, sex, birth weight less than the 10th centile, bronchopulmonary dysplasia, necrotizing enterocolitis, brain injury, and earlier neonatal discharge (lower quartile of postmenstrual age at discharge for gestation) as variables. Of 39 938 children discharged home (median [IQR] gestational age, 29 [27-31] weeks; 21 602 [54.1%] male), 1878 (4.7%) had unplanned PICU admission. More than half of admissions occurred within 50 days of neonatal discharge (1080 [57.5%]). Compared with summer, the risk of unplanned PICU admission following neonatal discharge was 2.58 times higher in winter and 2.35 times higher in autumn (winter: adjusted hazard ratio [aHR], 2.58; 95% CI, 1.68-3.95; autumn: aHR, 2.35; 95% CI, 1.84-2.99). Among children born at 28 to 31 weeks' gestational age, earlier neonatal discharge was associated with increased risk (aHR, 1.30; 95% CI, 1.13-1.49), but this was not true for children born younger than 28 weeks' gestational age. In this retrospective cohort study of preterm children, autumn and winter discharge were associated with the highest risk of unplanned PICU admission following neonatal discharge. For children born at 28 to 31 weeks' gestational age, discharge at lower postmenstrual age was also associated with increased risk. Further work is required to understand whether delaying neonatal discharge for some children born at 28 to 31 weeks' gestational age is beneficial and to consider the wider costs and implications of prolonging neonatal care.

Disease Pattern and Clinical Profile of Admitted Patients in Pediatric Intensive Care Unit of a Tertiary Care Hospital in Chattogram

Background: The care of critically ill children remains one of the most demanding and challenging aspects in the field of pediatrics. Pediatric Intensive Care Unit (PICU) aims at promoting early intervention and quality care for achieving good results and better prognosis. With the advancement in intensive care facilities, there is a dramatic increase in survival of critically ill children. It is usually offered to patients whose condition is potentially reversible and who have a good chance of surviving with intensive care support. Since these patients are critically ill, the outcome of intervention is sometimes difficult to predict. This study is aimed to assess the clinical profile of critically ill children presenting to the pediatric emergency room and then their admission pattern to the pediatric intensive care unit. This may help to assist intensivist and planners to pay due attention for better utilization of healthcare facilities. Better understanding leads to better management. Materials and methods: This is a cross-sectional study, conducted at the Pediatric Intensive Care Unit of Chattagram Maa Shishu-O-General Hospital from January to June of 2019. A total of 100 admitted cases were recruited and their symptoms and signs, clinical findings and diagnosis were recorded accordingly. All the patients were aged within 28 days to below 14 years. Results: Among the 100 study subjects, 66 were male and 34 were female. The mean age was 1.73 ± 2.6 years. Most children were admitted with respiratory distress though there were other accompanying signs and symptoms. The symptoms subjects commonly presented with were respiratory distress(76%), tachycardia(70%), lung crepitations (69%), tachypnea (68%), fever (67%), lethargy (59%), feeding difficulty (59%), convulsions (48%), low blood pressure (24%), hepatomegaly (19%), cyanosis (14%), edema (6%), congenital anomalies (4%). The clinical findings that led them to PICU admissions were bronchiolitis (4%), bronchopneumonia (42%), respiratory failure of any cause (4%), heart failure (7%), cyanotic congenital heart disease (8%), acyanoticcongenital heart disease (7%), meningitis (13%), encephalitis (12%), cerebral palsy with seizure disorder (21%), status epilepticus (2%), Gullein Barre Syndrome (3%), hyponatremic dehydration (6%), acute kidney injury (2%), acute leukemia (2%).In this study, neurological disorders such as cerebral palsy with seizure disorder and encephalitis and meningitis were among the top five in the diagnosis list. Septicemia with shock was also a very common finding promoting admission to PICU. GCS was found to be significantly lower in the above-mentioned disease conditions making admission to the ICU quite plausible. Conclusion: Children admitted to PICU may have multiple clinical findings and disease patterns. However, some diseases predominate the patient population admitted to PICU.The knowledge of clinical spectrum and epidemiological profile of critically ill children plays a significant role in the planning of health policies that would mitigate various factors related to the evolution of diseases prevalent in these sectors. Descriptive epidemiology focuses on identifying and reporting the pattern and frequency of events related to the health of a population. IAHS Medical Journal Vol 7(1), June 2024; 44-49

Incidence and factors associated with prolonged use of mechanical ventilation in pediatric intensive care unit in a single tertiary care hospital.

Invasive mechanical ventilation (IMV) is frequently used as a life-supporting device in Pediatric Intensive Care Units (PICU). To date, there are few studies evaluating the impact of prolonged mechanical ventilation (PMV) in children which is associated with high morbidity and mortality. We aimed to determine the incidence and factors associated with PMV in PICU at our institution. A retrospective review was performed of children aged 1 month to 18 years who were admitted to the PICU at Chiang Mai University Hospital, Thailand between January and December 2020. PMV was defined if the duration of IMV was ≥ 96 hours. Baseline characteristics and factors associated with PMV were analyzed by descriptive statistics, and univariable and multivariable logistic regression analysis, respectively. A p-value of < 0.05 was considered significant. Ninety-two episodes of IMV were performed in 90 children. The median (IQR) age of the children was 22.8 (7.2-111.9) months (male 64.1%). Forty-six of 92 (50%) children received PMV and 32.6% of children with PMV required a tracheostomy. Following multivariable analysis, factors associated with PMV were age <2 years old (OR 2.86, 95% CI 1.04-7.84, p = 0.041), male gender (OR 3.21, 95% CI 1.15-8.94, p = 0.026), and multiple antibiotics administration during PICU admission (OR 7.83, 95% CI 1.87-32.78, p = 0.005), respectively. Pediatric PMV was notably common, with younger age, male gender, and multiple antibiotic use contributing to higher risk. Developing weaning protocols and strategies to reduce PMV duration is crucial.

Musculoskeletal Sepsis in the Pediatric Intensive Care Unit

Background: Childhood bone and joint infection (BJI) ranges in severity, with the most unwell children requiring pediatric intensive care unit (PICU) support. We describe demographic and prehospital features of BJI cases associated with PICU admission and report treatment outcomes and costs for these cases. Methods: This study includes a retrospective cohort of children ≤15 years of age hospitalized with acute hematogenous osteomyelitis or septic arthritis in Auckland between 2018 and 2023. Cases admitted to PICU were compared to non-PICU hospitalized BJI cases. Direct medical hospitalization costs, treatment type and outcomes were described up to 1 year following discharge. Results: Of 563 BJI cases, 43 (8%) were admitted to PICU. PICU cases had shorter prehospital symptom duration (3.78 vs. 5.73 days, P = 0.0002). Sensitive Staphylococcus aureus was equally likely to cause disease in PICU and non-PICU cases (P = 0.86). Average hospitalization was longer (35.78 vs. 8.71 days, P ≤ 0.0001) for those admitted to PICU. Readmission and complication rates were both higher within the first year. Average cost per admission was $378,120 NZ dollars (±$796,891.64) for PICU cases versus $32,219 (±$201,797.33), P = 0.01 for cases not requiring PICU admission. In regression analysis, Māori ethnicity, previous history of infections and congenital conditions were statistically associated with PICU admission. Conclusion: In this study, children admitted to PICU with severe BJIs were more likely to have a history of congenital conditions or previous infections. Those of Māori ethnicity are overrepresented. Children treated in PICU have longer hospitalizations and experience more adverse outcomes at 1 year following discharge.

The association between composite measures of social vulnerability and PICU admission for status asthmaticus.

Current knowledge of the impact of socioeconomic factors on the risk of admission to the pediatric intensive care unit (PICU) for asthma is limited. Using composite measures of social vulnerability-Social Vulnerability Index (SVI) and Child Opportunity Index (COI) 2.0-we compared patients admitted for status asthmaticus to the PICU and pediatric ward at Children's Hospital Los Angeles (CHLA). We hypothesized patients with a high SVI and low COI are at higher risk for PICU admission. Patients were identified using ICD-10 codes for asthma. Primary outcome was admission to PICU versus ward for status asthmaticus. Patient-registered residential street addresses were geocoded and spatially joined to SVI and COI 2.0 data at the census tract level. Univariate and regression analyses using the patient's SVI, COI 2.0, and admission location were conducted. From January 2017 to March 2022, there were 2458 admissions matched to addresses from 1983 distinct patients. The overall median SVI for all patients was 0.86 (IQR 0.6, 0.9). Overall median COI was 25.0 (IQR 10, 50). There was no difference in SVI or COI for admission to the PICU versus the ward. However, children requiring multiple hospital admissions for asthma were associated with higher SVI and lower COI. Children admitted to CHLA for asthma had an elevated SVI and low COI. There was no difference between admission locations based on SVI or COI scores. This indicates we care for children at increased socioeconomic risk, but this did not increase PICU use for asthma.

Mortality following admission to the paediatric intensive care unit: A Swedish longitudinal cohort study.

This study aimed to compare outcomes post-admission to a Swedish paediatric intensive care unit (PICU) in children with complex chronic conditions (CCC) and without CCC. In this observational registry-based study, consecutive admissions to the Astrid Lindgren Children's Hospital PICU from 1 January 2008 to 31 December 2016 were analysed. Data on demographics, predicted death rates (PDR), admission diagnoses and causes of death were collected. Mortality was recorded up to 15 years after admission and compared between groups. Patients with CCC constituted 64.6% (n = 3026) of PICU admissions and 83.5% (n = 111) of PICU deaths. The crude mortality rate in PICU was 2.84% overall. CCC-patients were 2.83 times more likely to die in PICU compared to non-CCC (OR 2.83; 95% CI: 1.78-4.49). Mortality increased in the CCC-cohort up to 5 years after PICU discharge, while non-CCC patients generally survived if they survived in PICU. Of the patients who died in PICU, the median PDR was 22.9% for CCC-patients and 66.5% in the non-CCC cohort. Children with CCC accounted for most admissions and deaths in PICU. Despite lower severity of illness scores upon admission, CCC patients were nearly three times more likely to die in PICU compared to non-CCC patients.

Clinical outcomes and the impact of treatment modalities in children with carbapenem-resistant Enterobacteriaceae bloodstream infections: a retrospective cohort study from a tertiary university hospital.

The increasing prevalence of carbapenem-resistant Enterobacteriaceae (CRE) infections among children represents a significant global concern, leading to elevated mortality rates. The aim of this study was to evaluate the risk factors, outcomes, 30-day mortality rates and contributing factors in children with CRE bloodstream infections (CRE-BSIs). Data regarding demographic characteristics, treatment approaches and outcomes of hospitalized children aged 0-18 years diagnosed with CRE-BSIs between January 2018 and December 2022 were extracted from medical records. Mortality within 30 days of diagnosis and the predictive factors were analysed. A total of 114 children, with a median age of 11 months (range: 6-69.5), were included. All cases of CRE-BSIs were either healthcare associated or hospital acquired and presented with at least one underlying comorbidity. A previous history of CRE colonization or infection rate was 48.2% (55/114). Klebsiella pneumoniae 87.7% (100/114) was the most frequently isolated microorganism, with a 30-day mortality rate of 14% (16/114). Multivariate analysis identified paediatric intensive care unit admission, invasive mechanical ventilation, inotropic support and thrombocytopenia due to CRE-BSIs as the most discriminative predictors for 30-day mortality (P < 0.001). Central venous catheter (CVC) removal was associated with a reduced mortality rate (P = 0.012). High-dose prolonged infusion of MEM-based or polymyxin-based antibiotic combinations did not impact survival. Lower MEM MIC values were associated with improved survival. The mortality rate of CRE-BSI is notably high in childhood. The use of antibiotic combination strategies did not demonstrate a significant impact on 30-day survival; however, the removal of CVCs was found to lower mortality rates.

53 Clinical characteristics and outcomes of children hospitalized with RSV-associated acute respiratory infections

Abstract Background Respiratory syncytial virus (RSV) is one of the most common acute respiratory infections (ARI) in infants and young children. After the relaxation of COVID-19 pandemic restrictions, children’s hospitals worldwide experienced unprecedented volumes and severity in presentation of children admitted with ARIs, such as RSV. It is unknown whether the increase in volumes was also associated with changes in the typical demographic, severity and outcomes of patients with RSV infections. Objectives To describe sociodemographic characteristics, clinical presentation, management including diagnosis and disposition and clinical outcomes of children under the age of 18 years admitted to tertiary care paediatric hospital with RSV-associated ARI. Design/Methods Observational cohort of children and adolescents aged 0-18 years admitted to two large Canadian children’s hospitals between July 1, 2022 - December 31, 2022, who had microbiological evidence of RSV infection. Detailed clinical and demographic information were extracted, including admission and discharge diagnoses, diagnostic tests, viral and bacterial testing, interventions, and respiratory settings. Clinical outcomes and complications were collected, including length of hospital admission, paediatric intensive care unit (PICU) admission, need for invasive mechanical ventilation, disposition, and death. Results There were 455 patients admitted with an RSV infection, of which a third (35.0%, n=146) were transfers from other hospitals. Cases were 41.0% male and the median age was 1.22 years (interquartile range [IQR] 0.19-3.06). Nearly two-thirds of patients (62.0%, n=284) were younger than 2 years of age, 8.6% had a history of prematurity. One third (31.0%, n=142) of patients had at least one documented comorbid condition, the most common diagnosis was asthma (6.6%). In addition to RSV, 3.5% (n=16) of patients had a simultaneous bacterial pathogen identified. Most patients (73%, n=330) were only RSV positive, while 24% (n=109) had two pathogens identified. One quarter (25.9%) were admitted to the PICU. The median length of hospital stay was 3 days (IQR 2.00-5.00) and for those admitted to the PICU, nearly two thirds of patients (63.0%, n=75) were admitted for less than 4 days. 0 patients died. The most common discharge diagnosis in 61.0% of patients (n=279) was bronchiolitis. There were 56 patients (12.3%) who had an unscheduled return visit to the ED within 30 days of discharge with 23.0% (n=13) requiring readmission to the hospital. Conclusion There continues to be a substantial volume of hospitalizations secondary to RSV infection, predominantly in those &amp;lt;2 years of age, with a prominent diagnosis of bronchiolitis. A quarter of patients had notable severity requiring PICU admission.
