Severe acute respiratory syndrome coronavirus-2-related and imputable deaths in children: results from the French pediatric national registry.

BACKGROUND: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is responsible for an important mortality rate worldwide. We aimed to evaluate the actual imputability of SARS-CoV-2 on the mortality rate associated with SARS-CoV-2-related illnesses in the pediatric intensive care unit (PICU). Secondary objectives were to identify risk factors for death. METHODS: This national multicenter comparative study comprised all patients under 18 years old with positive SARS-CoV-2 polymerase chain reactions (PCRs) [acute corona virus disease 2019 (COVID-19) or incidental SARS-CoV-2 infection] and/or pediatric inflammatory multisystem syndrome (PIMS) recorded in the French PICU registry (PICURe) between September 1, 2021, and August 31, 2022. Included patients were classified and compared according to their living status at the end of their PICU stay. Deceased patients were evaluated by four experts in the field of pediatric infectiology and/or pediatric intensive care. The imputability of SARS-CoV-2 as the cause of death was classified into four categories: certain, very probable, possible, or unlikely, and was defined by any of the first three categories. RESULTS: There were 948 patients included of which 43 died (4.5%). From this, 26 deaths (67%) could be attributed to SARS-CoV-2 infection, with an overall mortality rate of 2.8%. The imputability of death to SARS-CoV-2 was considered certain in only one case (0.1%). Deceased patients suffered more often from comorbidities, especially heart disease, neurological disorders, hematological disease, cancer, and obesity. None of the deceased patients were admitted for pediatric inflammatory multisystem syndrome (PIMS). Mortality risk factors were male gender, cardiac comorbidities, cancer, and acute respiratory distress syndrome. CONCLUSIONS: SARS-CoV-2 mortality in the French pediatric population was low. Even though the imputability of SARS-CoV-2 on mortality was considered in almost two-thirds of cases, this imputability was considered certain in only one case.

NT-proBNP course during MIS-C post-COVID-19: an observational study.

Multisystem inflammatory syndrome in children (MIS-C or PIMS-TS) is a severe disease. N-terminal pro-B-type natriuretic peptide (NT-proBNP) is used for positive and differential diagnosis, diagnosis of complications and severity, and cardiogenic shock prediction. However, contrasting cut-offs have been suggested. The aims of the present study were to compare NT-proBNP values depending on the time of measurement and to describe the NT-proBNP course during the MIS-C episode. The data from a single-centre cohort observational study on the impact of time to diagnosis, defined as the time from first symptom to diagnosis of MIS-C, were used for the purpose of this study, with an extended period of inclusion from May 2020 to April 2023. The timing and level of all NT-proBNP samples available for each patient were retrospectively collected. Thirty-seven children (18 (49%) females, median age 8.8 years, 14 (38%) with shock) were included. Until diagnosis, NT-proBNP increased with time and was significantly higher at 6 days from first symptoms than at 3 days (median (interquartile range) 32,933 (7773-61,592) versus 1994 (1291-4190) pg/mL, respectively, p = 0.031). From diagnosis, NT-proBNP decreased by at least 50% after 3.0 (2.1-5.3) days (n = 12) when NT-proBNP at diagnosis was low ≤ 11,000 pg/mL versus 1.8 (0.7-3.4) days (n = 16) when NT-proBNP at diagnosis was high (p = 0.040), and after 3.6 (2.4-5.9) days (n = 7) when fever persisted after 48 h versus 1.8 (0.8-3.0) days (n = 21) when fever resolved before 48 h (p = 0.004).  Conclusions: During the MIS-C episode, NT-proBNP increased over time until diagnosis and treatment. It dropped faster thereafter in children with high NT-proBNP at diagnosis > 11,000 pg/mL and slower in case of persistent fever. What is Known: • NT-proBNP is useful in MIS-C for positive and differential diagnosis, diagnosis of complications and severity, and cardiogenic shock prediction. • Contrasting cut-offs for differential diagnosis and severity assessment have been suggested. What is New: • Before diagnosis, NT-proBNP increases with time and is significantly higher at 6 days from first symptoms than at 3 days suggesting different cut-offs depending on the timing of measurement. • From diagnosis and treatment initiation, the 50% NT-proBNP drop occurs earlier in children with high NT-proBNP at diagnosis > 11,000 pg/mL and later in children with persistent fever.

Patient Characteristics and Severity Trajectories in a Pediatric Intermediate Care Unit.

OBJECTIVES: To describe the characteristics of patients admitted to Pediatric Intermediate Care Units (PImCU) and to assess their illness severity trajectories. METHODS: This prospective, observational, multicentre cohort study was conducted in seven French PImCUs between September 2012 and January 2014. All consecutive patients aged under 18 were included. The severity of illness was evaluated through the Paediatric Advanced Warning Score (PAWS), measured every 8 h for each patient. A latent class mixed model was used to identify severity trajectory classes. RESULTS: A total of 2868 patients were included. The median [interquartile range] age was 29 [5-103] mo and the median length of stay was 1 [1-3] d. The primary indication for admission was respiratory (44%). Almost 3% of the patients were subsequently transferred to a pediatric intensive care unit. Three severity trajectory classes were identified. In one class, comprising the largest proportion of patients, the PAWS was low on admission and did not change markedly over time. In this class, patients were older and had a shorter length of stay. The other two classes were characterized by a higher PAWS on admission and rapid or slow improvement. These patients were more severely ill, mostly due to respiratory failure. CONCLUSIONS: A large proportion of patients had a stable profile and no signs of severity which suggests that the stay in PImCU was not indicated but a part of these patients have remained stable perhaps because of the advanced monitoring and intensive nursing in these units. CLINICAL TRIAL REGISTRATION: The study was registered with ClinicalTrials.gov Protocol, Identifier: NCT02304341, ClinicalTrials.gov .

Anti-infective prescribing practices in critically ill children on continuous renal replacement therapy: a multicenter survey of French-speaking countries.

BACKGROUND: Use of continuous renal replacement therapy in children receiving anti-infective drugs may lead to inappropriate concentrations with risks related to treatment failure, toxicity and emergence of multidrug-resistant bacteria. We aimed to describe anti-infective prescribing practices in critically ill children undergoing continuous renal replacement therapy. METHODS: An online survey to assess continuous renal replacement therapy, anti-infective prescribing and therapeutic drug monitoring practices was sent by e-mail to physicians working in pediatric intensive care units through the French-speaking Group of Pediatric Intensive Care and Emergency medicine (GFRUP). RESULTS: From April 1st, 2021 to May 1st, 2021, 26/40 pediatric intensive care units participated in the survey, corresponding to a response rate of 65%. Twenty-one were located in France and five abroad. All pediatric intensive care units administered continuous renal replacement therapy, primarily with Prismaflex™ System. Anti-infective prescriptions were adjusted to the presence of continuous renal replacement therapy in 23 (88%) pediatric intensive care units mainly according to molecular weight in 6 (23%), molecule protein binding in 6 (23%) and elimination routes in 15 (58%) including residual diuresis in 9 (35%), to the continuous renal replacement therapy flow in 6 (23%) and to the modality of continuous renal replacement therapy used in 15 (58%), pediatric intensive care units. There was broad variability among pediatric intensive care units and among physicians within the same unit. Barriers to therapeutic drug monitoring were mainly an excessive delay in obtaining results in 11 (42%) and the lack of an on-site laboratory in 8 (31%) pediatric intensive care units. CONCLUSIONS: Our survey reported wide variability in anti-infective prescribing practices in children undergoing continuous renal replacement therapy, thus highlighting a gap in knowledge and the need for education and recommendations.

Visiting Policies and Parental Presence During PICU Admission: A Survey in French Units.

OBJECTIVES: To describe the policies about parent visiting and involvement in care during admission to French PICUs. DESIGN: A structured questionnaire was emailed to the chief of each of 35 French PICUs. Data about visiting policies, involvement in care, evolution of policies, and general characteristics were collected from April 2021 to May 2021. A descriptive analysis was conducted. SETTING: Thirty-five PICUs in France. PATIENTS: None. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Twenty-nine of 35 (83%) PICUs replied. Twenty-four-hour access for parents was reported for all PICUs responding. Other allowed visitors were grandparents (21/29, 72%) and siblings (19/29, 66%) with professional support. Simultaneous visits were restricted to two visitors in 83% (24/29) of PICUs. Family presence was always permitted during medical rounds for 20 of 29 (69%) PICUs. Most of the units rarely or never allowed parental presence during the most invasive procedures, such as central venous catheter placement (18/29, 62%) and intubation (22/29, 76%). CONCLUSIONS: Unrestricted access to the PICU, for both parents, was available in all responding French units. There were, however, restrictions on the number of visitors and the presence of other family members at the bedside. Moreover, permission for parental presence during care procedures was heterogenous, and mainly restricted. National guidelines and educational programs are needed to support family wishes and promote acceptance by healthcare providers in French PICUs.

Association between out-of-hospital cardiac arrest and survival in paediatric traumatic population: results from the French national registry.

BACKGROUND AND IMPORTANCE: Trauma is an important cause of paediatric out-of-hospital cardiac arrest (OHCA) with a high mortality rate. OBJECTIVES: The first aim of this study was to compare the survival rate at day 30 and at hospital discharge following paediatric traumatic and medical OHCA. The second aim was to compare the rates of return of spontaneous circulation and survival rates at hospital admission (Day 0). SETTING AND PARTICIPANTS: This multicentre comparative post-hoc study was conducted between July 2011 and February 2022 based on the French National Cardiac Arrest Registry data. All patients aged <18 years with OHCA were included in the study. OUTCOME MEASURES AND ANALYSIS: Patients with traumatic aetiology were matched with those with medical aetiology using propensity score matching. Endpoint was the survival rate at day 30. MAIN RESULTS: There were 398 traumatic and 1061 medical OHCAs. Matching yielded 227 pairs. In non-adjusted comparisons, days 0 and 30 survival rates were lower in the traumatic aetiology group than in the medical aetiology group [19.1% vs. 24.0%, odds ratio (OR) 0.75, 95% confidence interval (CI) 0.56-0.99, and 2.0% vs. 4.5%, OR 0.43, 95% CI, 0.20-0.92, respectively]. In adjusted comparisons, day 30 survival rate was lower in the traumatic aetiology group than in the medical aetiology group (2.2% vs. 6.2%, OR 0.36, 95% CI, 0.13-0.99). CONCLUSION: In this post-hoc analysis, paediatric traumatic OHCA was associated with a lower survival rate than medical cardiac arrest.

Risk of Admission to the Pediatric Intensive Care Unit for SARS-CoV-2 Delta and Omicron Infections.

BACKGROUND: The severity of SARS-CoV-2-related diseases in children remains unclear. This study aimed to describe the incidence of French pediatric intensive care units (PICUs) admissions with acute COVID-19, incidental positive SARS-CoV-2 test result, and multisystem inflammatory syndrome in children (MIS-C) during the delta and omicron variant periods. METHODS: This study used the French PICU registry to obtain data on all patients admitted to 41 French PICUs diagnosed with acute COVID-19, incidental positive SARS-CoV-2 test result, or MIS-C between August 30, 2021 and April 20, 2022. Data regarding the total number of positive SARS-CoV-2 polymerase chain reaction results according to the type of variants were obtained from the French National Public Health Agency. RESULTS: Of 745 children, 244 (32.8%) were admitted for acute COVID-19, 246 (33.0%) for incidental positive SARS-CoV-2 test results, and 255 (34.2%) for MIS-C. The incidence of each group was higher with delta than with omicron. The incidence rate ratios with the delta variant were 7.47 (95% CI, 4.22-13.26) for acute COVID-19, 4·78 (95% CI, 2.30-9.94) for incidental positive SARS-CoV-2 test results, and 10.46 (95% CI, 5.98-18.31) for MIS-C compared to the omicron variant. The median age was 66 (7.7-126.8) months; 314 (42%) patients had comorbidities. Patients with acute COVID-19 and incidental positive SARS-CoV-2 test results had similar proportions of comorbidities. No patient with MIS-C died, whereas the mortality rates in the acute COVID-19 and incidental positive SARS-CoV-2 test results groups were 6.8% and 3.8%, respectively. CONCLUSIONS: The incidence of acute COVID-19, incidental positive SARS-CoV-2 test results, and MIS-C admitted to the PICU were significantly higher with the delta variant than with the omicron variant.

Impact of time to diagnosis on the occurrence of cardiogenic shock in MIS-C post-COVID-19 infection.

BACKGROUND: In multisystem inflammatory syndrome in children (MIS-C), diagnostic delay could be associated with severity. This study aims to measure the time to diagnosis in MIS-C, assess its impact on the occurrence of cardiogenic shock, and specify its determinants. METHODS: A single-center prospective cohort observational study was conducted between May 2020 and July 2022 at a tertiary care hospital. Children meeting the World Health Organization MIS-C criteria were included. A long time to diagnosis was defined as six days or more. Data on time to diagnosis were collected by two independent physicians. The primary outcome was the occurrence of cardiogenic shock. Logistic regression and receiver operating characteristic curve analysis were used for outcomes, and a Cox proportional hazards model was used for determinants. RESULTS: Totally 60 children were assessed for inclusion, and 31 were finally analyzed [52% males, median age 8.8 (5.7-10.7) years]. The median time to diagnosis was 5.3 (4.2-6.2) days. In univariable analysis, age above the median, time to diagnosis, high C-reactive protein, and high N-terminal pro-B-type natriuretic peptide (NT-proBNP) were associated with cardiogenic shock [odds ratio (OR) 6.13 (1.02-36.9), 2.79 (1.15-6.74), 2.08 (1.05-4.12), and 1.70 (1.04-2.78), respectively]. In multivariable analysis, time to diagnosis ≥ 6 days was associated with cardiogenic shock [adjusted OR (aOR) 21.2 (1.98-227)]. Time to diagnosis ≥ 6 days had a sensitivity of 89% and a specificity of 77% in predicting cardiogenic shock; the addition of age > 8 years and NT-proBNP at diagnosis ≥ 11,254 ng/L increased the specificity to 91%. Independent determinants of short time to diagnosis were age < 8.8 years [aHR 0.34 (0.13-0.88)], short distance to tertiary care hospital [aHR 0.27 (0.08-0.92)], and the late period of the COVID-19 pandemic [aHR 2.48 (1.05-5.85)]. CONCLUSIONS: Time to diagnosis ≥ 6 days was independently associated with cardiogenic shock in MIS-C. Early diagnosis and treatment are crucial to avoid the use of inotropes and limit morbidity, especially in older children.

Severity of illness and organ dysfunction scoring systems in pediatric critical care: The impacts on clinician's practices and the future.

Severity and organ dysfunction (OD) scores are increasingly used in pediatric intensive care units (PICU). Therefore, this review aims to provide 1/ an updated state-of-the-art of severity scoring systems and OD scores in pediatric critical care, which explains 2/ the performance measurement tools and the significance of each tool in clinical practice and provides 3/ the usefulness, limits, and impact on future scores in PICU. The following two pediatric systems have been proposed: the PRISMIV, is used to collect data between 2 h before PICU admission and the first 4 h after PICU admission; the PIM3, is used to collect data during the first hour after PICU admission. The PELOD-2 and SOFApediatric scores were the most common OD scores available. Scores used in the PICU should help clinicians answer the following three questions: 1/ Are the most severely ill patients dying in my service: a good discrimination allow us to interpret that there are the most severe patients who died in my service. 2/ Does the overall number of deaths observed in my department consistent with the severity of patients? The standard mortality ratio allow us to determine whether the total number of deaths observed in our service over a given period is in adequacy with the number of deaths predicted, by considering the severity of patients on admission? 3/ Does the number of deaths observed by severity level in my department consistent with the severity of patients? The calibration enabled us to determine whether the number of deaths observed according to the severity of patients at PICU admission in a department over a given period is in adequacy with the number of deaths predicted, according to the severity of the patients at PICU admission. These scoring systems are not interpretable at the patient level. Scoring systems are used to describe patients with PICU in research and evaluate the service's case mix and performance. Therefore, the prospect of automated data collection, which permits their calculation, facilitated by the computerization of services, is a necessity that manufacturers should consider.

High dose of epinephrine does not improve survival of children with out-of-hospital cardiac arrest: Results from the French National Cardiac Arrest Registry.

Objectives: The pediatric resuscitation guidelines recommend the use of 0. 01 mg kg-1 epinephrine during a cardiac arrest; an epinephrine dose higher than that is not recommended. The first aim of this study was to determine the administration rate of high epinephrine dose during pediatric out-of-hospital cardiac arrest. The second aim was to compare the survival status in patients who received high or standard doses of epinephrine. Methods: This was a multicenter comparative post-hoc study conducted between January 2011 and July 2021 based on the French National Cardiac Arrest Registry data. All prepubescent (boys < 12 years old, girls < 10 years old) victims of an out-of-hospital cardiac arrest were included. To compare survival status and control bias, patients who received a high epinephrine dose were matched with those who received a standard epinephrine dose using propensity score matching. Results: The analysis included 755 patients; 400 (53%) received a high dose and 355 (47%) received a standard dose of epinephrine. The median dose (mg kg-1) per bolus was higher in the high-dose group than that in the standard dose group (0.04 vs. 0.01 mg kg-1, P < 0.001). Before matching, there was no between-group difference in the 30-day survival rate or survival status at hospital discharge. Matching yielded 288 pairs; there was no between-group difference in the 30-day survival rate or survival at hospital discharge (High dose, n = 5; standard dose, n = 12; Odds ratios: 2.40, 95% confidence interval: 0.85-6.81). Only 2 patients in the standard dose group had a good neurological outcome. Conclusion: More than 50% of the patients did not receive the recommended epinephrine dose during resuscitation. There was no association between patients receiving a high dose or standard dose of epinephrine with the 30-day survival or survival status at hospital discharge. Collaboration across multiple cardiac arrest registries is needed to study the application of pediatric guidelines.

Whole pulmonary assessment 1 year after paediatric acute respiratory distress syndrome: prospective multicentre study.

BACKGROUND: Long-term pulmonary sequelae, including 1-year thoracic computed tomography (CT) sequelae of paediatric acute respiratory distress syndrome (ARDS) remain unknown. The purpose of the study was to determine pulmonary abnormalities in child survivors of pulmonary (p-ARDS) and extra-pulmonary ARDS (ep-ARDS) 1 year after paediatric intensive care unit discharge (PICUD). METHODS: Prospective multicentre study in four paediatric academic centres between 2005 and 2014. Patients with ARDS were assessed 1 year after PICUD with respiratory symptom questionnaire, thoracic CT and pulmonary function tests (PFT). RESULTS: 39 patients (31 p-ARDS) aged 1.1-16.2 years were assessed. Respiratory symptoms at rest or exercise and/or respiratory maintenance treatment were reported in 23 (74%) of children with p-ARDS but in 1 (13%) of those with ep-ARDS. Thoracic CT abnormalities were observed in 18 (60%) of children with p-ARDS and 4 (50%) of those with ep-ARDS. Diffuse and more important CT abnormalities, such as ground glass opacities or mosaic perfusion patterns, were observed in 5 (13%) of children, all with p-ARDS. PFT abnormalities were observed in 30 (86%) of patients: lung hyperinflation and/or obstructive pattern in 12 (34%) children, restrictive abnormalities in 6 (50%), mild decrease in diffusing capacity in 2 (38%) and 6-min walking distance decrease in 11 (73%). Important PFT abnormalities were observed in 7 (20%) children, all with p-ARDS. Increasing driving pressure (max plateau pressure-max positive end-expiratory pressure) was correlated with increasing CT-scan abnormalities and increasing functional residual capacity (more hyperinflation) (p < 0.005). CONCLUSIONS: Children surviving ARDS requiring mechanical ventilation present frequent respiratory symptoms, significant CT-scan and PFT abnormalities 1 year after PICUD. This highlights the need for a systematic pulmonary assessment of these children. Trial registration The study was registered on Clinical Trials.gov PRS (ID NCT01435889).

Impact of puberty as threshold to differentiate outcome of out-of-hospital cardiac arrest care groups: a nationwide observational study in France.

BACKGROUND: Since 2005, the international guidelines for out-of-hospital cardiac arrest (OHCA) use puberty to differentiate paediatric and adult care. This threshold is mainly relied on the more frequent respiratory aetiologies in children. Hitherto, to the best of our knowledge, no study has compared the characteristics and outcomes of non-pubescent children, adolescents and adult patients with OHCA. In this study, we intended to describe the characteristics, outcome and factors associated with survival of patients who experienced OHCA in the three groups: children, adolescents (pubescent<18 years) and adults (<65 years), to assess the pertinence of the guidelines. METHODS: Data from the French national cardiac arrest registry (2012-2017) were used in this nationwide observational study. Victims of OHCA who were <65 years old were included. The characteristics and outcomes of children and adolescents, and adolescents and adults were compared. Logistic regression was performed in each group to identify factors associated with survival at day 30. RESULTS: We included 934 children, 433 adolescents and 26 952 adults. Respiratory aetiology was more frequent and shockable rhythm less frequent in children compared with adolescents (25.5% vs 17.2%, p=0.025 and 2.4% vs 6.8%, p<0.001, respectively). However, these differences were not observed between adolescents and adults (17.2% vs 14.1%, p=0.266 and 6.8% vs 10%, p=0.055, respectively). Between children and adolescents, and adolescents and adults, there was no significant difference in survival at day 30 (8.6%vs 9.8% and 9.8% vs 8.5%, respectively). For all groups, shockable initial rhythm was a factor of survival. CONCLUSION: Frequency of respiratory aetiologies and shockable rhythm were common in adolescents and adults and different between children and adolescents. These results indicate that puberty as a threshold in international guidelines seems to be relevant.

Increasing burden of viral bronchiolitis in the pediatric intensive care unit; an observational study.

PURPOSE: Viral bronchiolitis is a major cause of pediatric intensive care unit (PICU) admission. Insight in the trends of bronchiolitis-associated PICU admissions is limited, but imperative for future PICU resource and capacity planning. MATERIALS AND METHODS: We retrospectively studied trends in PICU admissions for bronchiolitis in six European sites, including three full national registries, between 2000 and 2019 and calculated population-based estimates per 100,000 children where appropriate. Information concerning risk factors for severe disease and use of invasive mechanical ventilation was also collected when available. RESULTS: In total, there were 15,606 PICU admissions for bronchiolitis. We observed an increase in the annual number, rate and estimates per 100,000 children of PICU admissions for bronchiolitis at all sites over the last two decades, while the proportion of patients at high risk for severe disease remained relatively stable. CONCLUSIONS: The international increased burden of bronchiolitis for the PICU is concerning, and warrants further international attention and investigation.

Refining the Pediatric Multiple Organ Dysfunction Syndrome.

Since its introduction into the medical literature in the 1970s, the term multiple organ dysfunction syndrome (or some variant) has been applied broadly to any patient with >1 concurrent organ dysfunction. However, the epidemiology, mechanisms, time course, and outcomes among children with multiple organ dysfunction vary substantially. We posit that the term pediatric multiple organ dysfunction syndrome (or MODS) should be reserved for patients with a systemic pathologic state resulting from a common mechanism (or mechanisms) that affects numerous organ systems simultaneously. In contrast, children in whom organ injuries are attributable to distinct mechanisms should be considered to have additive organ system dysfunctions but not the syndrome of MODS. Although such differentiation may not always be possible with current scientific knowledge, we make the case for how attempts to differentiate multiple organ dysfunction from other states of additive organ dysfunctions can help to evolve clinical and research priorities in diagnosis, monitoring, and therapy from largely organ-specific to more holistic strategies.

Pediatric Organ Dysfunction Information Update Mandate (PODIUM) Contemporary Organ Dysfunction Criteria: Executive Summary.

Prior criteria for organ dysfunction in critically ill children were based mainly on expert opinion. We convened the Pediatric Organ Dysfunction Information Update Mandate (PODIUM) expert panel to summarize data characterizing single and multiple organ dysfunction and to derive contemporary criteria for pediatric organ dysfunction. The panel was composed of 88 members representing 47 institutions and 7 countries. We conducted systematic reviews of the literature to derive evidence-based criteria for single organ dysfunction for neurologic, cardiovascular, respiratory, gastrointestinal, acute liver, renal, hematologic, coagulation, endocrine, endothelial, and immune system dysfunction. We searched PubMed and Embase from January 1992 to January 2020. Study identification was accomplished using a combination of medical subject headings terms and keywords related to concepts of pediatric organ dysfunction. Electronic searches were performed by medical librarians. Studies were eligible for inclusion if the authors reported original data collected in critically ill children; evaluated performance characteristics of scoring tools or clinical assessments for organ dysfunction; and assessed a patient-centered, clinically meaningful outcome. Data were abstracted from each included study into an electronic data extraction form. Risk of bias was assessed using the Quality in Prognosis Studies tool. Consensus was achieved for a final set of 43 criteria for pediatric organ dysfunction through iterative voting and discussion. Although the PODIUM criteria for organ dysfunction were limited by available evidence and will require validation, they provide a contemporary foundation for researchers to identify and study single and multiple organ dysfunction in critically ill children.

Scoring Systems for Organ Dysfunction and Multiple Organ Dysfunction: The PODIUM Consensus Conference.

CONTEXT: Multiple scores exist to characterize organ dysfunction in children. OBJECTIVE: To review the literature on multiple organ dysfunction (MOD) scoring systems to estimate severity of illness and to characterize the performance characteristics of currently used scoring tools and clinical assessments for organ dysfunction in critically ill children. DATA SOURCES: Electronic searches of PubMed and Embase were conducted from January 1992 to January 2020. STUDY SELECTION: Studies were included if they evaluated critically ill children with MOD, evaluated the performance characteristics of scoring tools for MOD, and assessed outcomes related to mortality, functional status, organ-specific outcomes, or other patient-centered outcomes. DATA EXTRACTION: Data were abstracted into a standard data extraction form by a task force member. RESULTS: Of 1152 unique abstracts screened, 156 full text studies were assessed including a total of 54 eligible studies. The most commonly reported scores were the Pediatric Logistic Organ Dysfunction Score (PELOD), pediatric Sequential Organ Failure Assessment score (pSOFA), Pediatric Index of Mortality (PIM), PRISM, and counts of organ dysfunction using the International Pediatric Sepsis Definition Consensus Conference. Cut-offs for specific organ dysfunction criteria, diagnostic elements included, and use of counts versus weighting varied substantially. LIMITATIONS: While scores demonstrated an increase in mortality associated with the severity and number of organ dysfunctions, the performance ranged widely. CONCLUSIONS: The multitude of scores on organ dysfunction to assess severity of illness indicates a need for unified and data-driven organ dysfunction criteria, derived and validated in large, heterogenous international databases of critically ill children.

Endotracheal intubation versus supraglottic procedure in paediatric out-of-hospital cardiac arrest: a registry-based study.

BACKGROUND: Out-of-hospital cardiac arrest (OHCA) in children is associated with a low survival rate. Conclusions in the literature are conflicting regarding the best way to handle ventilation. The purpose of this study was to assess the impact of two airway management strategies, endotracheal intubation (ETI) vs. supraglottic procedure, during cardiopulmonary resuscitation (CPR) on 30-day survival in paediatric OHCA. METHODS: This was a retrospective, observational, multicentre, registry-based study conducted from July 2011 to March 2018. All paediatric OHCA patients under 18 years of age and managed by a mobile intensive care unit were included. The primary endpoint was 30-day survival in a weighted population (based on propensity scores). RESULTS: Of 1579 children, 1355 (85.8%) received ETI and 224 (14.2%) received supraglottic ventilation during CPR. We observe a lower 30-day survival in the ETI group compared to the supraglottic group (7.7% vs. 14.3%, absolute difference, 6.6 percentage points; 95% confidence interval [CI], 2.3-12.0; propensity-adjusted odds ratio [paOR], 0.39; 95% CI, 0.25-0.62; p < 0.001), and also a poorer neurological outcome (paOR, 0.32; 95% CI, 0.19-0.54; p < 0.001). However, we did not identify any significant association between airway management strategy and return of spontaneous circulation (paOR, 1.15; 95% CI, 0.80-1.65; p = 0.46). CONCLUSIONS: The findings of this large cohort study suggest that ETI in paediatric OHCA, although performed by trained physicians, is associated with a worse outcome, regardless of traumatic or non-traumatic aetiology.

Are Nutritional Guidelines Followed in the Pediatric Intensive Care Unit?

Background: French (2014) and American (2017) pediatric guidelines recommend starting enteral nutrition (EN) early in pediatric intensive care. The aims of this study were to compare the applicability of the guidelines in the pediatric intensive care unit (PICU) and to identify risk factors of non-application of the guidelines. Methods: This retrospective, single-center study was conducted in a medical-surgical PICU between 2014 and 2016. All patients from 1 month to 18 years old with a length of stay >48 h and an exclusive EN at least 1 day during the PICU stay were included. The outcome variable was application of the 2014 and 2017 guidelines, defined by energy intakes ≥90% of the recommended intake at least 1 day as defined by both guidelines. The risk factors of non-application were studied comparing "optimal EN" vs. "non-optimal EN" groups for both guidelines. Results: In total, 416 children were included (mortality rate, 8%). Malnutrition occurred in 36% of cases. The mean energy intake was 34 ± 30.3 kcal kg-1 day-1. The 2014 and 2017 guidelines were applied in 183 (44%) and 296 (71%) patients, respectively (p < 0.05). Following the 2017 guidelines, enteral energy intakes were considered as "satisfactory enteral intake" for 335 patients (81%). Hemodynamic failure was a risk factor of the non-application of both guidelines. Conclusion: In our PICU, the received energy intake approached the level of intake recommended by the American 2017 guidelines, which used the predictive Schofield equations and seem more useful and applicable than the higher recommendations of the 2014 guidelines. Multicenter studies to validate the pediatric guidelines seem necessary.
