Pediatric Risk Of Mortality Research Articles

An observational study to evaluate the outcome of patients admitted in pediatric intensive care unit (PICU) using pediatric risk of mortality (PRISM-III) score in a tertiary care hospital of West Bengal

Background: Pediatric risk of mortality (PRISM III) score is used across the globe to predict the mortality of hospitalized children by an objective method based on 17 variables measured during first 24 h of admission in pediatric intensive care unit (PICU). Aims and Objectives: We have done this study to evaluate the cause, management and outcome of PICU admissions and also to find out the statistical significance of PRISM III score in predicting mortality. Materials and Methods: This observational prospective study was conducted for a period of 1 year in the PICU of a district Medical College of West Bengal among children 1–12 years age. They were divided into 4 groups according to the PRISM III scores of 1–10, 11–20, 21–30, and >30 and outcome in all the groups were recorded and analyzed. Results: Respiratory (25%), neurological (20.1%), and infectious (17.3%) etiology were major cause of PICU admission. About 17.4% patients needed mechanical ventilation, 31.2% Continuous Positive Airway Pressure and 66% patients inotropic support. Out of 144 cases, 117 discharged and 27 expired. Percentage of death is 100%, 44.4%, 21.6%, and 4.6% among child with PRISM III score of >30, 21–30, 11–21, and ≤10, respectively. Significant increase in mortality noted with increase in number of organ failures. Specificity and positive predictive value increases with higher PRISM III score and sensitivity and negative predictive value is more with low PRISM III score. Conclusion: PRISM III score can be used as a triage tool in limited resource settings for early initiation of intense management to high risk and salvageable cases.

Association Between Race/Ethnicity and Severity of Illness in Pediatric Cardiomyopathy and Myocarditis.

Previous reports demonstrate racial/ethnic differences in survival for children hospitalized with cardiomyopathy and myocarditis. The impact of illness severity, a potential mechanism for disparities, has not been explored. Using the Virtual Pediatric Systems (VPS, LLC), we identified patients ≤ 18 years old admitted to the intensive care unit (ICU) for cardiomyopathy/myocarditis. Multivariate regression models were used to evaluate the association between race/ethnicity and Pediatric Risk of Mortality (PRISM 3). Multivariate logistic and competing risk regression was used to examine the relationship between race/ethnicity and mortality, CPR, and ECMO. Black patients had higher PRISM 3 scores on first admission (𝛽 = 2.02, 95% CI: 0.15, 3.90). There was no difference in survival across race/ethnicity over multiple hospitalizations. Black patients were less likely to receive a heart transplant (SHR = 0.65, 95% CI: 0.45-0.92). Black and unreported race/ethnicity had higher odds of CPR on first admission (OR = 1.64, 95% CI: 1.01-2.45; OR = 2.12, 95% CI: 1.11-4.08, respectively). Black patients have higher severity of illness on first admission to the ICU, which may reflect differences in access to care. Black patients are less likely to receive a heart transplant. Additionally, Black patients and those with unreported race/ethnicity had higher odds of CPR, which was not mediated by severity of illness, suggesting variations in care may persist after admission.

The Various Scoring Systems in Pediatric Intensive Care Units: A Prospective Observational Study.

The discrimination power of the pediatric risk of mortality (PRISM), pediatric index of mortality (PIM), sequential organ failure assessment (SOFA), and pediatric logistic organ dysfunction (PELOD) may not always be true for countries such as India due to differences in factors from those nations where these scoring systems were validated. Therefore, this study was undertaken to determine and compare severity, course of illness, and outcomes in critically ill children admitted to the pediatric intensive care unit (PICU) using different scoring systems such as PRISM 4, PIM 3, PELOD 2, and the pediatric sequential organ failure assessment (pSOFA ) score, and to analyze the clinical spectrum and demographic profile of children admitted to the PICU. This was a prospective, single-center, observational study conducted in the PICU of the Indira Gandhi Institute of Medical Science, Patna, India, over two years. Two hundred children in the age group of one month to 14 years admitted to the PICU were recruited into the study. Prognostic scoring systems, including PRISM4 and PIM3, were used to compare the outcome, mortality, and length of PICU stay, whereas PELODS and pSOFA were descriptive scores that assessed the multiorgan dysfunction. A correlation between the different scoring systems and the outcome was determined. The majority of children (26.5%, n=53) were one to three years of age. The maximum number of patients was male (66.5%, n=133). Renal complications were the predominant admission diagnosis in 19% (n=38) of children. The mortality rate was found to be 18.5%. The mortality was most common in infants <1 year of age (n=11, 29.73%) and those of the male sex (n=22, 59.46%). A significant correlation was found between length of stay and mortality (p<0.00001). A significant positive correlation was observed between mortality and PRISM 4, PIM 3, PELOD 2, and pSOFA scores on the first day of admission (p<0.00001). The pSOFA and PELOD2 showed better discrimination power (area under the curve (AUC): 0.77 and 0.74, respectively). The study concluded that the pSOFA and PELOD2 scores are reliable predictors of mortality in critically ill children.

Evaluation of Patients with Acute Respiratory Distress Syndrome Followed on Mechanical Ventilator in a Tertiary Pediatric Intensive Care and the Factors That May Be Associated with Death in These Patients.

We aimed to evaluate the clinical, demographic, and laboratory characteristics of the patients followed up with pediatric acute respiratory distress syndrome in our pediatric intensive care unit and to determine the factors that have an effect on the outcomes. The medical records of 40 patients with acute respiratory distress syndrome who were followed up on mechanical ventilators in the pediatric intensive care unit of Adıyaman University were retrospectively scanned. From the medical records, the demographic data, clinical features, and laboratory characteristics were recorded. Eighteen of the patients were female and 22 were male. The mean age was 45.25 ± 56.63 months. A total of 27 (67.5%) of the patients were classified as pulmonary and 13 (32.5%) as extrapulmonary acute respiratory distress syndrome. Sixteen (40%) patients were followed in pressure-controlled mode only, 2 (5%) patients in volume-controlled mode only, and 22 (55%) patients in alternate modes. A total of 17 (42.5%) patients died. The median pediatric index of mortality, pediatric index of mortality-II, pediatric risk of mortality, and pediatric logistic organ dysfunction score values of the surviving patients were significantly lower than the dead patients. Median aspartate aminotransferase (P = .003) and lactate dehydrogenase (P = .008) values were found to be significantly higher in patients who died, while median pH values (P = .049) were found to be lower. The median length of stay in pediatric intensive care unit and duration of mechanical ventilators were significantly shorter in patients who died. Also, the median pediatric index of mortality, pediatric index of mortality-II, pediatric risk of mortality, and pediatric logistic organ dysfunction values of pulmonary acute respiratory distress syndrome patients were significantly lower than those of extrapulmonary acute respiratory distress syndrome patients. Despite advances in follow-up and management, mortality due to acute respiratory distress syndrome is still high. Mechanical ventilator duration, length of stay in pediatric intensive care unit, some mechanical ventilator parameters, mortality scores, and laboratory tests were associated with mortality. Alternatively, mechanical ventilator applications may reduce mortality rates.

Asthma Cases Treated With Inhaled Anesthetics or Extracorporeal Membrane Oxygenation: A Virtual Pediatric Systems Database Study of Outcomes.

Extracorporeal membrane oxygenation (ECMO) and/or inhaled anesthetics (IAs) are considered in the management of asthma when refractory to conventional therapy. We aimed to compare the outcomes of these two modalities in asthma PICU care and determine associated survival to hospital discharge among patients in a United States database. Retrospective analysis using the Virtual Pediatric Systems (VPS, LLC) database. PICUs participating in the VPS database. Patients less than 18 years old with diagnosis of asthma treated with IA and/or ECMO from January 2010 to December 2020. None. A total of 221 patients were included; 149 (67%) received ECMO, 62 (28%) received IA, and 10 (5%) received both interventions. We failed to identify any difference between the ECMO and IA groups in demographics, Pediatric Index of Mortality 2 percentage, Pediatric Risk of Mortality 3 score, Pediatric Logistic Organ Dysfunction score, or pre-intervention pH and Pa co2 levels. Use of ECMO versus IA was associated with lower pre-intervention Pa o2 (60 torr [7.99 kPa] vs 78 torr [10.39 kPa]; p < 0.001) and higher utilization of high-frequency oscillatory ventilation. We failed to identify an association between type of intervention (IA vs ECMO) and greater odds of survival (57/62 [92%] vs 128/149 [86%]; odds ratio [OR], 1.87; 95% CI, 0.67-5.21; p = 0.23). However, these data do not exclude the possibility that IA use is associated with more than five-fold greater odds of survival. ECMO use was associated with longer duration of intervention (5 vs 1.3 d; p < 0.001) and PICU length of stay (LOS) (13 vs 7 d; p < 0.001). As expected, ECMO versus IA was also associated with greater odds of undergoing bronchoscopy (34% vs 11%; OR, 3.7; 95% CI, 1.5-9.4; p = 0.004). In the VPS database of asthma management cases, we failed to identify an association between ECMO versus IA use and survival to hospital discharge. However, ECMO was associated with longer duration of intervention and PICU LOS.

Fluid balance in pediatric postoperative liver transplant recipients.

Positive fluid balance (FB) is associated with poor outcomes in critically ill children but has not been studied in pediatric liver transplant (LT) recipients. Our goal is to investigate the relationship between postoperative FB and outcomes in pediatric LT recipients. We performed a retrospective cohort study of first-time pediatric LT recipients at a quaternary care children's hospital. Patients were stratified into three groups based on their FB in the first 72h postoperatively: <10%, 10-20%, and > 20%. Outcomes were pediatric intensive care unit (PICU) and hospital length of stay, ventilator-free days (VFD) at 28 days, day 3 severe acute kidney injury, and postoperative complications. Multivariate analyses were adjusted for age, preoperative admission status, and Pediatric Risk of Mortality (PRISM)-III score. We included 129 patients with median PRISM-III score of 9 (interquartile range, IQR 7-15) and calculated Pediatric End-stage Liver Disease score of 15 (IQR 2-23). A total of 37 patients (28.7%) had 10-20% FB, and 26 (20.2%) had >20% FB. Greater than 20% FB was associated with an increased likelihood of an additional PICU day (adjusted incident rate ratio [aIRR] 1.62, 95% CI: 1.18-2.24), an additional hospital day (aIRR 1.39, 95% CI: 1.10-1.77), and lower likelihood of a VFD at 28 days (aIRR 0.85, 95% CI: 0.74-0.97). There were no differences between groups in the likelihood of postoperative complications. In pediatric LT recipients, >20% FB at 72hpostoperatively is associated with increased morbidities, independent of age and severity of illness. Additional studies are needed to explore the impact of fluid management strategies on outcomes.

Major morbidity and mortality associated with delays to emergent surgery in children: a risk-adjusted analysis.

Delay of emergency surgery contributes to morbidity and mortality, and physiologic status affects outcomes of patients requiring emergent surgery. Our purpose was to determine whether delays to emergent surgery in children were associated with increased major morbidity or mortality in a risk-adjusted population. We performed a retrospective review of class 1 (≤ 60 min to operating room) surgical procedures from July 11, 2011, to July 30, 2016, at BC Children's Hospital, Vancouver. Data sources included the operating room database, patient charts, American Society of Anesthesiologists classification, Neonatal Acute Physiology (SNAP II) and Pediatric Risk of Mortality (PRISM III) scores, time from booking to operating room and outcome. Patients were classified as being at low or high risk for death. We defined major morbidity as unintended loss of an organ, limb or function related to surgery, and delay to surgery as more than 60 minutes from booking to in room. We used the χ2 test for univariate analysis and logistic regression for multivariate analysis. There were 384 cases (367 patients), 223 high-risk and 161 low-risk. The median age was 4 years (range 0 d-18 yr). Overall, 184 cases (47.9%) were delayed. Major morbidity occurred in 94 cases (24.5%), and 28 patients (7.6%) (all in the high-risk group) died. The mean time to the operating room was 1.46 hours for patients with major morbidity/mortality and 1.17 hours for those without. After adjustment for risk level, multivariate analysis showed delay to surgery to be associated with 85% increased odds of morbidity and/or mortality (adjusted odds ratio 1.85, 95% confidence interval 1.20-2.94) compared to no delay. Delay to emergent surgery was associated with a significant increase in major morbidity and/or mortality. Children who require emergency surgery need their care prioritized by not only operating room teams but also hospitals and government; otherwise, they will continue to experience unintended consequences.

Performance of Brazilian Pediatric Risk of Severity Model for Illness (Brprism) Compared to Pediatric Index of Mortality and Pediatric Risk of Mortality 2

Introduction: The best prognosis score with which to evaluate high-risk patients upon admission into pediatric intensive care is not well established in resource-limited settings. The objective of study was to formulate a risk-of-illness severity model for pediatric mortality to be applied upon PICU admission in resource-limited settings. Methods: Our study was designed to develop an illness severity index and a prognostic model for critically ill children. A prospective, observational multicenter pilot study, performed between February 1995 and October 1999, evaluated the variables, methodology and statistical techniques for the development of a model. A single-center prospective cohort study, performed between November 1999 and October 2004, collected information from consecutive admissions into the Pediatric Intensive Care Unit (PICU) at a high-complexity university, teaching, and reference hospital in São Paulo, Brazil. Results: In the pilot study, 1,459 patients (a PICU mortality rate of 16%) were included, and in the second study, 1,033 patients (a PICU mortality rate of 13.9% and a hospital mortality rate of 6.9% after PICU discharge) were included. We used multivariable regression to determine two probabilistic models; the first addressed survival and the overall probability of death (hospital plus PICU deaths), and the second was conditional (i.e., PICU death). An illness severity index stratified these probabilities into three risk strata: low-, medium- and high-risk patients. In the final step, the new death probabilities were estimated using a Bayesian adjustment. Conclusions: The model estimates three probabilities (survival, death in the PICU and death in the hospital after PICU discharge) stratified into three risk categories. To the best of our knowledge, this is the first study using a Bayesian adjustment to determine a prognosis and illness severity, and it should enable us to make therapeutic adjustments and provide appropriate counseling for high-risk patients in resource-limited settings.

Clinical Features and Management of Status Epilepticus in the Pediatric Intensive Care Unit.

Status epilepticus (SE) is associated with significant morbidity and mortality in children. SE in the pediatric intensive care unit (PICU) are not well characterized. The aim of this study is to retrospectively investigate the clinical features and treatment of seizures in children admitted to the PICU of our hospital. We retrospectively examined the clinical characteristics of patients aged between 1 month and 18 years who were admitted to our hospital with SE or who were diagnosed with SE after hospitalization and were followed up with continuous electroencephalographic monitoring between January 2015 and December 2019. A total of 88 patients with SE, 50 (56.8%) boys and 38 (43.2%) girls, were included. The median age was 24 months (interquartile range, 12-80 months). When we evaluate the continuous electroencephalographic monitoring data, 27 (30.7%) were lateralized, 20 (22.7%) were multifocal, 30 (34.1%) were generalized, and 11 (12.5%) were bilateral independent epileptic activity. Seventy nine patients (89.8%) were evaluated as convulsive status epilepticus (CSE) and 9 (10.2%) as nonconvulsive status epilepticus (NCSE). Pediatric Risk of Mortality (PRISM III) score and mortality of patients with NCSE were higher ( P = 0.004 and P = 0.046, respectively). Thirteen eight patients (43.1%) were diagnosed as SE, 38 patients (43.1%) as refractory SE, and 12 patients (13.6%) as super-refractory SE. The overall mortality rate was 10.2%. Status epilepticus is a neurological emergency that causes mortality and morbidity. Electroencephalographic monitoring is important for the recognition of seizures and rapid intervention. No superiority of second-line treatments or combined treatments was demonstrated in patients with SE.

The end-tidal alveolar dead space fraction for risk stratification during the first week of invasive mechanical ventilation: an observational cohort study

BackgroundThe end-tidal alveolar dead space fraction (AVDSf = [PaCO2−PETCO2]/PaCO2) is a metric used to estimate alveolar dead space. Higher AVDSf on the first day of mechanical ventilation is associated with mortality and fewer ventilator-free days. It is not clear if AVDSf is associated with length of ventilation in survivors, how AVDSf performs for risk stratification beyond the first day of ventilation, or whether AVDSf adds predictive value to oxygenation (oxygenation index [OI]) or severity of illness (Pediatric Risk of Mortality [PRISM III]) markers.MethodsRetrospective single-center observational cohort study of children and young adults receiving invasive mechanical ventilation. In those with arterial or capillary blood gases, AVDSf was calculated at the time of every blood gas for the first week of mechanical ventilation.ResultsThere were 2335 children and young adults (median age 5.8 years [IQR 1.2, 13.2]) enrolled with 8004 analyzed AVDSf values. Higher AVDSf was associated with mortality and longer length of ventilation in survivors throughout the first week of ventilation after controlling for OI and PRISM III. Higher OI was not associated with increased mortality until ≥ 48 h of ventilation after controlling for AVDSf and PRISM III. When using standardized variables, AVDSf effect estimates were generally higher than OI for mortality, whereas OI effect estimates were generally higher than AVDSf for the length of ventilation in survivors. An AVDSf > 0.3 was associated with a higher mortality than an AVDSf < 0.2 within each pediatric acute respiratory distress syndrome severity category.The maximum AVDSf within 12 h of intensive care unit admission demonstrated good risk stratification for mortality (AUC 0.768 [95% CI 0.732, 0.803]). AVDSf did not improve mortality risk stratification when added to PRISM III but did improve mortality risk stratification when added to the gas exchange components of PRISM III (minimum 12-h PaO2 and maximum 12-h PCO2) (p < 0.00001).ConclusionsAVDSf is associated with mortality and length of ventilation in survivors throughout the first week of invasive mechanical ventilation. Some analyses suggest AVDSf may better stratify mortality risk than OI, whereas OI may better stratify risk for prolonged ventilation in survivors than AVDSf.

Pediatric sepsis diagnostic and prognostic biomarkers: pancreatic stone protein, copeptin, and apolipoprotein A-V

BackgroundWe assessed serum concentrations of pancreatic stone protein (PSP), copeptin, and apolipoprotein A-V (APOA5) biomarkers for the diagnosis and prognosis of pediatric sepsis, a condition associated with high mortality.MethodsThis prospective study included 180 children admitted to the Pediatric Intensive Care Unit and 100 healthy controls at Menoufia University Hospital. Pediatric Risk of Mortality (PRISM), Pediatric Index of Mortality-2 (PIM2), and Pediatric Sequential Organ Failure Assessment (pSOFA) scores were calculated. Serum PSP, copeptin and APOA5 were measured once within 24 h of admission.ResultsPSP, copeptin, and APOA5 were significantly higher in the patients than in the controls (p < 0.001). PSP and copeptin were increased among children who required mechanical ventilation (MV), had multiple organ dysfunctions, and were non-survivors, but APOA5 was decreased in those children. Logistic regression analyses showed that high pSOFA, high PSP and copeptin, low APOA5, and use of MV were associated with mortality. The receiver operating characteristic revealed that the area under the curve (AUC) for APOA5, copeptin, and PSP (0.965, 0.960, and 0.868, respectively) demonstrated high sensitivity (96%, 94%, and 80%) for sepsis diagnosis. The AUC values for PSP, copeptin, and APOA5 were 0.709, 0.705, and 0.571, respectively, with sensitivities of 74%, 58%, and 58% for mortality prediction.ConclusionsPSP, copeptin, and APOA5 are promising diagnostic biomarkers for pediatric sepsis but inadequate predictors of mortality.ImpactApolipoprotein A-V (APOA5), copeptin, and pancreatic stone protein (PSP) are acute-phase proteins with diagnostic value in evaluating critically ill pediatric patients with sepsis and detecting sepsis severity.PSP and copeptin had the power to discriminate non-survivors from survivors.APOA5 was less powerful than the other biomarkers in discriminating between survivors and non-survivors.

Nutritional Support in Children Meeting the At-Risk for Pediatric Acute Respiratory Distress Syndrome Criteria.

To examine associations between early enteral nutrition (EN) and PICU outcomes in a cohort of children meeting the 2015 Pediatric Acute Lung Injury Consensus Conference "at-risk" for pediatric acute respiratory distress syndrome (ARF-PARDS) criteria. This was a single-center, electronic health record-based retrospective chart review. We included children less than or equal to 18 years-old admitted to our mixed medical-surgical PICU from January 2017 to December 2018 who met ARF-PARDS criteria within 48 hours of admission. Children were categorized as receiving "early" EN if feeds were initiated within 48 hours of admission. All others were categorized as "delayed" EN. Extracted data included demographics, illness characteristics including primary diagnosis and Pediatric Risk of Mortality (PRISM) III score, respiratory support and oxygenation indices, nutritional data, and PICU length of stay (LOS). The primary outcome of interest was subsequent diagnosis of PARDS. Of 201 included children, 152 (75.6%) received early EN. The most common admission diagnoses were pneumonia, bronchiolitis, and influenza. Overall, 21.4% (n = 43) of children developed PARDS. Children receiving early EN had a subsequent diagnosis of PARDS less often then children receiving delayed EN (15.1% vs 40.8%; p < 0.001), an association that persisted after adjusting for patient demographics and illness characteristics, including PRISM III and diagnosis (adjusted odds ratio, 0.24; 95% CI, 0.10-0.58; p = 0.002). Early EN was also associated with a shorter PICU LOS in univariate analysis (2.2 d [interquartile range, 1.5-3.4 d] vs 4.2 d [2.7-8.9 d]; p < 0.001). In this single-center, retrospective cohort study, compared with children with ARF-PARDS who received late EN, those who received early EN demonstrated a reduced odds of subsequent diagnosis of PARDS, and an unadjusted reduction in PICU LOS when compared with delayed EN. Prospective studies should be designed to confirm these findings.

Early period intensive care follow-up after liver transplantation in children: a single center experience.

Liver transplantation (LT) is a well-established, life-saving treatment for children with irreversible acute and chronic liver failure (LF). We aimed to evaluate the factors associated with morbidity and mortality in the early period of LT in children by reviewing our pediatric intensive care unit (PICU) experience. We reviewed children`s medical records followed in the PICU after LT between May 2015-August 2021, including demographic parameters, indications for LT, operative variables, respiratory and circulatory support requirements, LT-related complications and survival. During this period, 40 pediatric patients who underwent LT were evaluated. LT was performed in 35 (87.5%) cases of chronic liver disease and 5 (12.5%) cases of acute liver failure. Twenty-four patients had chronic liver failure due to cholestatic liver disease. The patients` Pediatric Risk of Mortality (PRISM) III score was 18.82±SD (2-58) at PICU admission. 1-year survival was 87.5%, and overall survival was 85%. Younger age, low body weight, preoperative pediatric end-stage liver disease (PELD), and model for end-stage liver disease (MELD) values of 20 and higher were important risk factors for unfavorable outcomes after living donor liver transplantation (LDLT). These risk factors are both associated with technically more challenging vascular and bile duct reconstruction and higher complication rates, and increased mortality during the early period after LT. The early period of optimum PICU management in pediatric LT recipients is crucial for successful outcomes, which is also related to the patients` characteristics, disease severity scores, and surgical procedures.

Mortality Rate and Risk Factors in Pediatric Intensive Care Unit of Imam Hossein Children's Hospital in Isfahan: A Prospective Cross-Sectional Study.

Various studies have conducted to report the mortality rates and its risk factors in pediatric intensive care unit. This study aimed to determine the mortality prevalence and risk factors in PICU of Imam Hossein Children's Hospital in Isfahan, which is the main referral pediatric hospital in the center of Iran. This study was performed on 311 patients during a period of 9 months. The questionnaire which included age, gender, length of stay in the PICU and hospital, mortality, history of resuscitation in other wards and readmission, the causes and sources of hospitalization, pediatric risk of mortality (PRISM)-III score, respiratory supports, morbidities like nosocomial infections, acute kidney injury (AKI), multiple organ dysfunction syndrome (MODS) confirmed by pediatric sequential organ failure assessment score (P-SOFA) and glycemic disorders was filled out. One hundred and seventy-seven (56.9%) were males and 103 (33%) were belonged to the age group of 12-59 months. The most prevalent causes of hospitalization were status epilepticus (12.9%) and pneumonia (11.2%). Mortality rate was 12.2%. The significant factors associated with mortality were readmission and history of resuscitation. PRISM-III index showed a significant difference between nonsurvivors and survivors (7.05 ± 6.36 vs. 3.36 ± 4.34, P = 0.001). Complications like AKI, hypoglycemia, MODS and disseminated intravascular coagulation (DIC), length of mechanical ventilation significantly correlated with mortality. Mortality rate was less than that of other developing countries (12.2%) and this was associated with some risk factors included readmission, history of resuscitation, PRISM-III Index; complications like AKI, acute respiratory distress syndrome (ARDS), DIC, mechanical ventilation duration, MODS, hypoglycemia, and P-SOFA index.

PRISM III Score Predicts Short-Term Outcome in Children with ARDS on Conventional and High-Frequency Oscillatory Ventilation.

Therapeutic recommendations for pediatric acute respiratory distress syndrome (PARDS) include conventional (CMV) and rescue high-frequency oscillatory mode (HFOV) of mechanical ventilation (MV). The pediatric risk of mortality (PRISM) is a frequently used mortality score for critically ill patients. In search of methods to recognize those patients, we analyzed the PRISM III score as a potential predictor of the short-term outcome in MV subjects with PARDS. A retrospective five-year study of PARDS in children on MV was conducted in the Pediatric ICU. Seventy patients were divided into two groups (age group &lt;1 year and age group 1-7 years). The PRISM III score was used to assess the 28-day outcome and possible development of complications. The most common causes of PARDS were pneumonia and sepsis. Male sex, malnourishment, sepsis, and shock were significant indicators of poor outcome. The PRISM III score values were significantly higher in those who died, as well as in subjects requiring HFOV. The score had a significant prognostic value for short-term mortality. There was no significant difference in outcome based on the comparison of two modes of ventilation. A significantly higher score was noted in subjects who developed sepsis and cardiovascular insufficiency. The PRISM III score is a fair outcome predictor during the 28-day follow-up in MV subjects with PARDS, regardless of the ventilation mode.

1314: INCREASED MEDICAL SEVERITY OF TRAUMA ADMISSIONS TO THE PICU DURING THE COVID-19 PANDEMIC

Introduction: It has been suggested that the coronavirus-19 disease (COVID-19) pandemic and associated community containment measures led to hesitancy among patients and their parents/guardians to report to hospitals for care. We hypothesized that the clinical condition of trauma patients admitted to the PICU was more severe during the COVID-19 pandemic in 2020 and early 2021 compared to previous years. Methods: We completed a retrospective, cross-sectional, study at a tertiary children’s hospital by comparing admissions to our PICU between March 2020 – March 2021, during which COVID-19 and community pandemic mitigation measures occurred, to those during the same period in the previous three years. All patients admitted to the PICU for trauma were included. Severity was measured using the pediatric risk of mortality (PRISM) score estimated probability of death. Trauma admissions between COVID-19 and non-COVID-19 epochs were compared using negative binomial regression. Demographic and clinical characteristics of patients admitted during pre-COVID-19 and COVID-19 epochs were compared using Fisher exact and Mann-Whitney U rank sum tests. The normality of data was assessed using the Shapiro-Wilk test. Results: Total trauma PICU admissions during COVID-19 pandemic months were similar to the same months in the preceding three years (mean 4.5/month, 95%-CI: 3.5 – 5.9/month vs. mean 3.6/month 95%-CI: 3.0 – 4.3/month, P = 0.133), although overall PICU admissions per month were lower (-19%, P< 0.001). Trauma patients admitted during COVID-19 had estimated median mortality more than twice as high as patients admitted during the non-COVID epoch (1.1%, interquartile range: 0.6 – 1.8% vs. 0.5%, interquartile range: 0.3 – 1.3%, P = 0.002). Age, sex, race and type of trauma (motor vehicle accident/gunshot wound/fall/all-terrain vehicle or bike accident/assault) were similar between the two time periods (all P > 0.05). Conclusions: These findings suggest that the COVID-19 pandemic was associated with increased severity in pediatric traumatic injuries, and possible hesitation to seek care earlier. These findings add to existing knowledge about increased trauma severity at presentation during a period of communicable disease spread and mitigation measures; these results may provide insight for future outbreak management.

Organ Dysfunction Among Children Meeting Brain Death Criteria: Implications for Organ Donation.

Over 70% of pediatric organ donors are declared deceased by brain death (BD) criteria. Patients with these devastating neurologic injuries often have accompanying multiple organ dysfunction. This study was performed to characterize organ dysfunction in children who met BD criteria and were able to donate their organs compared with those deemed medically ineligible. Retrospective cohort study. PICU at a quaternary care children's hospital. Patients with International Classification of Diseases , 9th Edition codes corresponding to BD between 2012 and 2018 were included. Demographics, comorbidities, Pediatric Risk of Mortality (PRISM)-III, and injury mechanisms were derived from the medical record. Organ dysfunction was quantified by evaluating peak daily organ-specific variables. Fifty-eight patients, from newborn to 22 years old, were included with a median PRISM-III of 34 (interquartile range [IQR], 26-36), and all met criteria for multiple organ dysfunction syndrome (MODS). Thirty-four of 58 BD children (59%) donated at least one organ. Of the donors (not mutually exclusive proportions), 10 of 34 donated lungs, with a peak oxygenation index of 11 (IQR, 8-23); 24 of 34 donated their heart (with peak Vasoactive Inotrope Score 23 [IQR, 18-33]); 31 of 34 donated kidneys, of whom 16 of 31 (52%) had evidence of acute kidney injury; and 28 of 34 patients donated their liver, with peak alanine transferase (ALT) of 104 U/L (IQR, 44-268 U/L) and aspartate aminotransferase (AST) of 165 U/L (IQR, 94-434 U/L). Organ dysfunction was similar between heart and lung donors and respective medically ineligible nondonors. Those deemed medically ineligible to donate their liver had higher peak ALT 1,518 U/L (IQR, 986-1,748 U/L) ( p = 0.01) and AST 2,200 U/L (IQR, 1,453-2,405 U/L) ( p = 0.01) compared with liver donors. In our single-center experience, all children with BD had MODS, yet more than one-half were still able to donate organs. Future research should further evaluate transplant outcomes of dysfunctional organs prior to standardizing donation eligibility criteria.

Characteristics and timing of mortality in children dying in pediatric intensive care: a 5-year experience.

Pediatric intensive care units (PICUs), where children with critical illnesses are treated, require considerable manpower and technological infrastructure in order to keep children alive and free from sequelae. In this retrospective comparative cohort study, hospital records of patients aged 1 month to 18 years who died in the study PICU between January 2015 and December 2019 were reviewed. A total of 2,781 critically ill children were admitted to the PICU. The mean±standard deviation age of 254 nonsurvivors was 64.34±69.48 months. The mean PICU length of stay was 17 days (range, 1-205 days), with 40 children dying early (<1 day of PICU admission). The majority of nonsurvivors (83.9%) had comorbid illnesses. Children with early mortality were more likely to have neurological findings (62.5%), hypotension (82.5%), oliguria (47.5%), acidosis (92.5%), coagulopathy (30.0%), and cardiac arrest (45.0%) and less likely to have terminal illnesses (52.5%) and chronic illnesses (75.6%). Children who died early had a higher mean age (81.8 months) and Pediatric Risk of Mortality (PRISM) III score (37). In children who died early, the first three signs during ICU admission were hypoglycemia in 68.5%, neurological symptoms in 43.5%, and acidosis in 78.3%. Sixty-seven patients needed continuous renal replacement therapy, 51 required extracorporeal membrane oxygenation support, and 10 underwent extracorporeal cardiopulmonary resuscitation. We found that rates of neurological findings, hypotension, oliguria, acidosis, coagulation disorder, and cardiac arrest and PRISM III scores were higher in children who died early compared to those who died later.

Time to appropriate antimicrobial therapy serves an independent prognostic indicator in children with nosocomial Klebsiella pneumoniae bloodstream infection

We tend to investigate the connection between time to appropriate therapy (TTAT) and prognosis in pediatric patients with nosocomial Klebsiella pneumoniae (K. pneumoniae) bloodstream infection, and find the optimal cutoff point for the empirical administration of antimicrobials. This retrospective study was conducted in Children’s Hospital of Chongqing Medical University, and inpatients with nosocomial K. pneumoniae bloodstream infection were finally enrolled. We applied the Classification and Regression Tree (CART) analysis to find the TTAT cutoff point and the Logistic Regression analysis to evaluate prognostic indicators. The incidence of septic shock and mortality was 17.91% (12/67) and 13.43% (9/67), respectively. The CART-derived TTAT cutoff point was 10.7 h. The multivariate logistic regression analysis indicated delayed therapy (TTAT ≥ 10.7 h), pediatric risk of mortality (PRISM) III scores ≥ 10, time to positivity (TTP) ≤ 13 h, and requiring for invasive mechanical ventilation were independently associated with the incidence of septic shock (Odds ratio [OR] 9.87, 95% Confidence interval [CI] 1.46–66.59, P = 0.019; OR 9.69, 95% CI 1.15–81.39, P = 0.036; OR 8.28, 95% CI 1.37–50.10, P = 0.021; OR 6.52, 95% CI 1.08–39.51, P = 0.042; respectively) and in-hospital mortality (OR 22.19, 95% CI 1.25–393.94, P = 0.035; OR 40.06, 95% CI 2.32–691.35, P = 0.011; OR 22.60, 95% CI 1.78–287.27, P = 0.016; OR 12.21, 95% CI 1.06–140.67, P = 0.045; respectively).Conclusions TTAT is an independent predictor of poor outcomes in children with nosocomial K. pneumoniae bloodstream infection. Initial appropriate antimicrobial therapy should be administrated timely and within 10.7 h from the onset of bloodstream infection is recommended.
