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.

To provide optimal, equitable care to patients, hospital systems must have intentional efforts to advance health equity. We present both intentional and actionable steps that our senior executive leadership prioritized to improve the health equity of the children and families we serve and to create a more inclusive working and learning environment for our employees, staff, faculty and trainees in our academic pediatric medical center. The four key concepts or lessons learned that we found essential to successfully advancing and sustaining equity, diversity, and inclusion (EDI) in our academic pediatric medical center were to: 1) Prioritize the strategy for EDI at the levels of the Board of Trustees and senior executive hospital leadership, 2) Collaborate with multi-disciplinary departments, offices, programs, and subject matter experts, 3) Take an Academic Approach by creating educational initiatives and scholarship in EDI, and (4) Commit to intentionality and accountability in the work by developing and tracking metrics for EDI and health equity safety disparities. Our hospital’s approach to its EDI goals and initiatives can serve as a roadmap for other academic medical centers and healthcare organizations in their efforts to improve health equity for all patients, families, and communities.

CONTEXT Cardiovascular dysfunction is associated with poor outcomes in critically ill children. OBJECTIVE We aim to derive an evidence-informed, consensus-based definition of cardiovascular dysfunction in critically ill children. DATA SOURCES Electronic searches of PubMed and Embase were conducted from January 1992 to January 2020 using medical subject heading terms and text words to define concepts of cardiovascular dysfunction, pediatric critical illness, and outcomes of interest. STUDY SELECTION Studies were included if they evaluated critically ill children with cardiovascular dysfunction and assessment and/or scoring tools to screen for cardiovascular dysfunction and assessed mortality, functional status, organ-specific, or other patient-centered outcomes. Studies of adults, premature infants (≤36 weeks gestational age), animals, reviews and/or commentaries, case series (sample size ≤10), and non–English-language studies were excluded. Studies of children with cyanotic congenital heart disease or cardiovascular dysfunction after cardiopulmonary bypass were excluded. DATA EXTRACTION Data were abstracted from each eligible study into a standard data extraction form, along with risk-of-bias assessment by a task force member. RESULTS Cardiovascular dysfunction was defined by 9 elements, including 4 which indicate severe cardiovascular dysfunction. Cardiopulmonary arrest (>5 minutes) or mechanical circulatory support independently define severe cardiovascular dysfunction, whereas tachycardia, hypotension, vasoactive-inotropic score, lactate, troponin I, central venous oxygen saturation, and echocardiographic estimation of left ventricular ejection fraction were included in any combination. There was expert agreement (>80%) on the definition. LIMITATIONS All included studies were observational and many were retrospective. CONCLUSIONS The Pediatric Organ Dysfunction Information Update Mandate panel propose this evidence-informed definition of cardiovascular dysfunction.

Atrial fibrillation (AFib) is the most common tachyarrhythmia of the heart in adults and is associated with an increased risk for stroke and heart failure. It can be described as irregularly irregular, foci in the atrium that set up chaotic atrial circuits and irregular rapid contraction of the atrium with loss of consistent atrio-ventricular synchrony due to decremental conduction at the atrio-ventricular node. The challenge was to identify predictive features of ECG signals with variable time and spatial components. These features were extracted from 8528 single lead ECG recordings and then input to a gradient boosting classifier. The trained model could classify AFib with an F1 score of 0.83. Present in the dataset were three other rhythm classes; Normal Sinus Rhythm, Other, and Noisy. The F1 scores achieved for these classes were 0.91, 0.77, and 0.66 respectively.

ObjectivesWe sought to identify risk factors for mortality and morbidity during the Norwood hospitalization in newborn infants with hypoplastic left heart syndrome and other single right ventricle anomalies enrolled in the Single Ventricle Reconstruction trial.MethodsPotential predictors for outcome included patient- and procedure-related variables and center volume and surgeon volume. Outcome variables occurring during the Norwood procedure and before hospital discharge or stage II procedure included mortality, end-organ complications, length of ventilation, and hospital length of stay. Univariate and multivariable Cox regression analyses were performed with bootstrapping to estimate reliability for mortality.ResultsAnalysis included 549 subjects prospectively enrolled from 15 centers; 30-day and hospital mortality were 11.5% (63/549) and 16.0% (88/549), respectively. Independent risk factors for both 30-day and hospital mortality included lower birth weight, genetic abnormality, extracorporeal membrane oxygenation (ECMO) and open sternum on the day of the Norwood procedure. In addition, longer duration of deep hypothermic circulatory arrest was a risk factor for 30-day mortality. Shunt type at the end of the Norwood procedure was not a significant risk factor for 30-day or hospital mortality. Independent risk factors for postoperative renal failure (n=46), sepsis (n=93), increased length of ventilation, and hospital length of stay among survivors included genetic abnormality, lower center/surgeon volume, open sternum, and post-Norwood operations.ConclusionsInnate patient factors, ECMO, open sternum, and lower center/surgeon volume are important risk factors for postoperative mortality and/or morbidity during the Norwood hospitalization.
