Abstract
BACKGROUND AND OBJECTIVES Medication reconciliation is a complex, but necessary, process to prevent patient harm from medication discrepancies. Locally, the steps of medication reconciliation are completed consistently; however, medication errors still occur, which suggest process inaccuracies. We focused on removal of unnecessary medications as a proxy for accuracy. The primary aim was to increase the percentage of patients admitted to the pediatric hospital medicine service with at least 1 medication removed from the home medication list by 10% during the hospital stay by June of 2022. METHODS Using the Model for Improvement, a multidisciplinary team was formed at a children's hospital, a survey was completed, and multiple Plan-Do-Study-Act cycles were done focusing on: 1. simplifying electronic health record processes by making it easier to remove medications; 2. continuous resident education about the electronic health record processes to improve efficiency and address knowledge gaps; and 3. auditing charts and real-time feedback. Data were monitored with statistical process control charts. RESULTS The project exceeded the goal, improving from 35% to 48% of patients having at least 1 medication removed from their home medication list. Improvement has sustained for 12 months. CONCLUSIONS The combination of interventions including simplifying workflow, improving education, and enhancing accountability resulted in more patients with medications removed from their home medication list.

Abstract
OBJECTIVES Identification of children with sepsis-associated multiple organ dysfunction syndrome (MODS) at risk for poor outcomes remains a challenge. We sought to the determine reproducibility of the data-driven "persistent hypoxemia, encephalopathy, and shock" (PHES) phenotype and determine its association with inflammatory and endothelial biomarkers, as well as biomarker-based pediatric risk strata. DESIGN We retrained and validated a random forest classifier using organ dysfunction subscores in the 2012-2018 electronic health record (EHR) dataset used to derive the PHES phenotype. We used this classifier to assign phenotype membership in a test set consisting of prospectively (2003-2023) enrolled pediatric septic shock patients. We compared profiles of the PERSEVERE family of biomarkers among those with and without the PHES phenotype and determined the association with established biomarker-based mortality and MODS risk strata. SETTING Twenty-five PICUs across the United States. PATIENTS EHR data from 15,246 critically ill patients with sepsis-associated MODS split into derivation and validation sets and 1,270 pediatric septic shock patients in the test set of whom 615 had complete biomarker data. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The area under the receiver operator characteristic curve of the modified classifier to predict PHES phenotype membership was 0.91 (95% CI, 0.90-0.92) in the EHR validation set. In the test set, PHES phenotype membership was associated with both increased adjusted odds of complicated course (adjusted odds ratio [aOR] 4.1; 95% CI, 3.2-5.4) and 28-day mortality (aOR of 4.8; 95% CI, 3.11-7.25) after controlling for age, severity of illness, and immunocompromised status. Patients belonging to the PHES phenotype were characterized by greater degree of systemic inflammation and endothelial activation, and were more likely to be stratified as high risk based on PERSEVERE biomarkers predictive of death and persistent MODS. CONCLUSIONS The PHES trajectory-based phenotype is reproducible, independently associated with poor clinical outcomes, and overlapped with higher risk strata based on prospectively validated biomarker approaches.

Abstract
INTRODUCTION/BACKGROUND Unmet need for seasonal influenza vaccination administration to pediatric patients exists at national and local levels. Vaccination during the perioperative period remains controversial, though opportunity exists to meet vaccination need through perioperative programs. The initial SMART Aim of this quality improvement initiative was to establish and increase seasonal influenza vaccination rate in eligible patients during in person preoperative clinic visits in a pediatric perioperative surgical home (PSH) to 10%. Informed by each prior season's experience, we increased our SMART Aim target for vaccinations in seasons two and three to 15 and 18%, respectively. METHODS Following the Model for Improvement methodology, the PSH team developed and implemented a perioperative pediatric influenza vaccination program. Across three influenza seasons, key interventions included updates to organizational perioperative vaccination policy, obtaining material influenza vaccination supplies, development of EHR tools, PSH staff education, and communication with patient-families. Rate of eligible patients receiving influenza vaccination at their PSH clinic appointment was tracked over time. Influenza vaccination rates were reported monthly during Season 1, then weekly during seasons two and three. The balancing measure was same day surgery case cancellations related to influenza vaccination given at PSH clinic appointment. Statistical analysis methods utilized include Shewart's control chart and statistical process control (SPC) standards. Special cause variation was determined by eight or more consecutive data points above or below the centerline. RESULTS The influenza vaccination rates in each of the three influenza seasons exceeded vaccination rate goals of 10, 15, and 18%, respectively. A total of 695 vaccines have been administered since program inception. No same day surgical case cancellations were observed as balancing measure. CONCLUSIONS Over three consecutive influenza vaccination seasons, we safely established and met vaccination rate goals of 10, 15, and 18% to eligible patients during preoperative clinic visits within a pediatric PSH system. Through iterative PDSA cycles, we continue to identify opportunities for future improvement. This suggests that the perioperative period presents opportunity for seasonal influenza vaccination with potential program expansion to include routine vaccines of childhood.

Abstract
BACKGROUND Free thyroxine (fT4) is often ordered when not indicated. The goal of the current study was to use quality improvement tools to identify and implement an optimal approach to reduce inappropriate fT4 testing throughout a large pediatric hospital system. METHODS After reviewing evidence-based guidelines and best practices, a thyroid-stimulating hormone with reflex to fT4 test and an outpatient thyroid order panel with clinical decision support at order entry, along with several rounds of provider education and feedback, were implemented. Outpatient and inpatient order sets and system preference lists were reviewed with subject matter experts and revised when appropriate. Tracking metrics were identified. Automated monthly run charts and statistical process control charts were created using data retrieved from the electronic health record. Charts established baseline data, balancing measure data, monitored the impact of interventions, and identified future interventions. RESULTS Over a 44-month period, among nonendocrinology providers, a reduction in fT4 and thyroid-stimulating hormone co-orders from 67% to 15% and an increase in reflex fT4 tests from 0% to 77% was obtained in inpatient and outpatient settings. Direct cost savings as a result of performing 5179 fewer fT4 tests over 3 years was determined to be $45 800. CONCLUSIONS After implementation of a reflex fT4 test, a novel order panel with clinical decision support, provider education, and changes to ordering modes, a large and sustainable reduction in fT4 tests that was associated with significant cost savings was achieved among nonendocrinology providers.

Abstract
ABSTRACT Background: Multiple-organ dysfunction syndrome disproportionately contributes to pediatric sepsis morbidity. Humanin (HN) is a small peptide encoded by mitochondrial DNA and thought to exert cytoprotective effects in endothelial cells and platelets. We sought to test the association between serum HN (sHN) concentrations and multiple-organ dysfunction syndrome in a prospectively enrolled cohort of pediatric septic shock. Methods: Human MT-RNR2 ELISA was used to determine sHN concentrations on days 1 and 3. The primary outcome was thrombocytopenia-associated multiorgan failure (TAMOF). Secondary outcomes included individual organ dysfunctions on day 7. Associations across pediatric sepsis biomarker (PERSEVERE)-based mortality risk strata and correlation with platelet and markers of endothelial activation were tested. Results: One hundred forty subjects were included in this cohort, of whom 39 had TAMOF. The concentration of sHN was higher on day 1 relative to day 3 and among those with TAMOF phenotype in comparison to those without. However, the association between sHN and TAMOF phenotype was not significant after adjusting for age and illness severity in multivariate models. In secondary analyses, sHN was associated with presence of day 7 sepsis-associated acute kidney injury ( P = 0.049). Furthermore, sHN was higher among those with high PERSEVERE-mortality risk strata and correlated with platelet counts and several markers of endothelial activation. Conclusion: Future investigation is necessary to validate the association between sHN and sepsis-associated acute kidney injury among children with septic shock. Furthermore, mechanistic studies that elucidate the role of HN may lead to therapies that promote organ recovery through restoration of mitochondrial homeostasis among those critically ill.

Abstract
OBJECTIVES Post-ICU admission cumulative positive fluid balance (PFB) is associated with increased mortality among critically ill patients. We sought to test whether this risk varied across biomarker-based risk strata upon adjusting for illness severity, presence of severe acute kidney injury (acute kidney injury), and use of continuous renal replacement therapy (CRRT) in pediatric septic shock. DESIGN Ongoing multicenter prospective observational cohort. SETTING Thirteen PICUs in the United States (2003-2023). PATIENTS Six hundred and eighty-one children with septic shock. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Cumulative percent PFB between days 1 and 7 (days 1-7 %PFB) was determined. Primary outcome of interest was complicated course defined as death or persistence of greater than or equal to two organ dysfunctions by day 7. Pediatric Sepsis Biomarker Risk Model (PERSEVERE)-II biomarkers were used to assign mortality probability and categorize patients into high mortality (n = 91), intermediate mortality (n = 134), and low mortality (n = 456) risk strata. Cox proportional hazard regression models with adjustment for PERSEVERE-II mortality probability, presence of sepsis-associated acute kidney injury on day 3, and use of CRRT, demonstrated that time-dependent variable days 1-7%PFB was independently associated with an increased hazard of complicated course. Risk-stratified analyses revealed that each 10% increase in days 1-7 %PFB was associated with increased hazard of complicated course only among patients with high mortality risk strata (adjusted hazard ratio 1.24 (95% CI, 1.08-1.43), p = 0.003). However, this association was not causally mediated by PERSEVERE-II biomarkers. CONCLUSIONS Our data demonstrate the influence of cumulative %PFB on the risk of complicated course in pediatric septic shock. Contrary to our previous report, this risk was largely driven by patients categorized as having a high mortality risk based on PERSEVERE-II biomarkers. Incorporation of such prognostic enrichment tools in randomized trials of restrictive fluid management or early initiation of de-escalation strategies may inform targeted application of such interventions among at-risk patients.

Abstract
Background Sepsis poses a grave threat, especially among children, but treatments are limited due to clinical and biological heterogeneity among patients. Thus, there is an urgent need for precise subclassification of patients to guide therapeutic interventions. Methods We used clinical, laboratory, and biomarker data from a prospective multi-center pediatric septic shock cohort to derive phenotypes using latent profile analyses. Thereafter, we trained a support vector machine model to assign phenotypes in a hold-out validation set. We tested interactions between phenotypes and common sepsis therapies on clinical outcomes and conducted transcriptomic analyses to better understand the phenotype-specific biology. Finally, we compared whether newly identified phenotypes overlapped with established gene-expression endotypes and tested the utility of an integrated subclassification scheme. Findings Among 1,071 patients included, we identified two phenotypes which we named 'inflamed' (19.5%) and an 'uninflamed' phenotype (80.5%). The 'inflamed' phenotype had an over 4-fold risk of 28-day mortality relative to those 'uninflamed'. Transcriptomic analysis revealed overexpression of genes implicated in the innate immune response and suggested an overabundance of developing neutrophils, pro-T/NK cells, and NK cells among those 'inflamed'. There was no significant overlap between endotypes and phenotypes. However, an integrated subclassification scheme demonstrated varying survival probabilities when comparing endophenotypes. Interpretation Our research underscores the reproducibility of latent profile analyses to identify clinical and biologically informative pediatric septic shock phenotypes with high prognostic relevance. Pending validation, an integrated subclassification scheme, reflective of the different facets of the host response, holds promise to inform targeted intervention among those critically ill.

Abstract
BACKGROUND Acute kidney injury (AKI) occurs commonly in pediatric septic shock and increases morbidity and mortality. Early identification of high-risk patients can facilitate targeted intervention to improve outcomes. We previously modified the renal angina index (RAI), a validated AKI prediction tool, to improve specificity in this population (sRAI). Here, we prospectively assess sRAI performance in a separate cohort. METHODS A secondary analysis of a prospective, multicenter, observational study of children with septic shock admitted to the pediatric intensive care unit from 1/2019 to 12/2022. The primary outcome was severe AKI (≥ KDIGO Stage 2) on Day 3 (D3 severe AKI), and we compared predictive performance of the sRAI (calculated on Day 1) to the original RAI and serum creatinine elevation above baseline (D1 SCr > Baseline +). Original renal angina fulfillment (RAI +) was defined as RAI ≥ 8; sepsis renal angina fulfillment (sRAI +) was defined as RAI ≥ 20 or RAI 8 to < 20 with platelets < 150 × 103/µL. RESULTS Among 363 patients, 79 (22%) developed D3 severe AKI. One hundred forty (39%) were sRAI + , 195 (54%) RAI + , and 253 (70%) D1 SCr > Baseline + . Compared to sRAI-, sRAI + had higher risk of D3 severe AKI (RR 8.9, 95%CI 5-16, p < 0.001), kidney replacement therapy (KRT) (RR 18, 95%CI 6.6-49, p < 0.001), and mortality (RR 2.5, 95%CI 1.2-5.5, p = 0.013). sRAI predicted D3 severe AKI with an AUROC of 0.86 (95%CI 0.82-0.90), with greater specificity (74%) than D1 SCr > Baseline (36%) and RAI + (58%). On multivariable regression, sRAI + retained associations with D3 severe AKI (aOR 4.5, 95%CI 2.0-10.2, p < 0.001) and need for KRT (aOR 5.6, 95%CI 1.5-21.5, p = 0.01). CONCLUSIONS Prediction of severe AKI in pediatric septic shock is important to improve outcomes, allocate resources, and inform enrollment in clinical trials examining potential disease-modifying therapies. The sRAI affords more accurate and specific prediction than context-free SCr elevation or the original RAI in this population.

Abstract
ABSTRACT Background: Endothelial activation is a key driver of multiple organ dysfunction syndrome (MODS). Soluble endoglin (sENG) is expressed by mature and progenitor endothelial cells and thought to have angiogenic properties. We sought to determine the association between sENG and pediatric sepsis-associated MODS. Methods: Prospective observational study of pediatric septic shock. Primary outcome of interest was complicated course-a composite of death by (or) MODS on day 7 of illness. Secondary outcomes included individual organ dysfunctions. Endothelial biomarkers including sENG were measured using multiplex Luminex assays among patients with existing data on the Pediatric Sepsis Biomarker Risk Model (PERSEVERE-II) data. Multivariable regression was used to test the independent association between sENG and clinical outcomes. Serum sENG concentrations across PERSEVERE-II mortality risk strata and correlations with established markers of endothelial dysfunction were determined. Results: Three hundred six critically ill children with septic shock were included. Serum sENG concentrations were higher among those with primary and secondary outcomes of interest, with the exception of acute neurological dysfunction. Soluble endoglin was independently associated with increased odds of complicated course (adjusted odds ratio, 1.53; 95% confidence interval, 1.02-2.27; P = 0.038) and acute renal dysfunction (adjusted odds ratio, 1.84; 95% confidence interval, 1.18-2.876; P = 0.006). Soluble endoglin demonstrated graded responses across PERSEVERE-II risk strata and was positively correlated with endothelial biomarkers, except angiopoietin-1. Conclusions: Serum sENG is independently associated with complicated course and acute renal dysfunction in pediatric septic shock. Future studies are required to validate our observational data, and mechanistic studies are necessary to elucidate whether endoglin plays an organ-specific role in the development or resolution of acute renal dysfunction in sepsis.

Abstract
Objective Identification of children with sepsis-associated multiple organ dysfunction syndrome (MODS) at risk for poor outcomes remains a challenge. Data-driven phenotyping approaches that leverage electronic health record (EHR) data hold promise given the widespread availability of EHRs. We sought to externally validate the data-driven 'persistent hypoxemia, encephalopathy, and shock' (PHES) phenotype and determine its association with inflammatory and endothelial biomarkers, as well as biomarker-based pediatric risk-strata. Design We trained and validated a random forest classifier using organ dysfunction subscores in the EHR dataset used to derive the PHES phenotype. We used the classifier to assign phenotype membership in a test set consisting of prospectively enrolled pediatric septic shock patients. We compared biomarker profiles of those with and without the PHES phenotype and determined the association with established biomarker-based mortality and MODS risk-strata. Setting 25 pediatric intensive care units (PICU) across the U.S. Patients EHR data from 15,246 critically ill patients sepsis-associated MODS and 1,270 pediatric septic shock patients in the test cohort of whom 615 had biomarker data. Interventions None. Measurements and Main Results The area under the receiver operator characteristic curve (AUROC) of the new classifier to predict PHES phenotype membership was 0.91(95%CI, 0.90-0.92) in the EHR validation set. In the test set, patients with the PHES phenotype were independently associated with both increased odds of complicated course (adjusted odds ratio [aOR] of 4.1, 95%CI: 3.2-5.4) and 28-day mortality (aOR of 4.8, 95%CI: 3.11-7.25) after controlling for age, severity of illness, and immuno-compromised status. Patients belonging to the PHES phenotype were characterized by greater degree of systemic inflammation and endothelial activation, and overlapped with high risk-strata based on PERSEVERE biomarkers predictive of death and persistent MODS. Conclusions The PHES trajectory-based phenotype is reproducible, independently associated with poor clinical outcomes, and overlap with higher risk-strata based on validated biomarker approaches.

Abstract
BACKGROUND Sepsis-associated acute kidney injury (SA-AKI) is associated with high morbidity, with no current therapies available beyond continuous renal replacement therapy (CRRT). Systemic inflammation and endothelial dysfunction are key drivers of SA-AKI. We sought to measure differences between endothelial dysfunction markers among children with and without SA-AKI, test whether this association varied across inflammatory biomarker-based risk strata, and develop prediction models to identify those at highest risk of SA-AKI. METHODS Secondary analyses of prospective observational cohort of pediatric septic shock. Primary outcome of interest was the presence of ≥ Stage II KDIGO SA-AKI on day 3 based on serum creatinine (D3 SA-AKI SCr). Biomarkers including those prospectively validated to predict pediatric sepsis mortality (PERSEVERE-II) were measured in Day 1 (D1) serum. Multivariable regression was used to test the independent association between endothelial markers and D3 SA-AKI SCr. We conducted risk-stratified analyses and developed prediction models using Classification and Regression Tree (CART), to estimate risk of D3 SA-AKI among prespecified subgroups based on PERSEVERE-II risk. RESULTS A total of 414 patients were included in the derivation cohort. Patients with D3 SA-AKI SCr had worse clinical outcomes including 28-day mortality and need for CRRT. Serum soluble thrombomodulin (sTM), Angiopoietin-2 (Angpt-2), and Tie-2 were independently associated with D3 SA-AKI SCr. Further, Tie-2 and Angpt-2/Tie-2 ratios were influenced by the interaction between D3 SA-AKI SCr and risk strata. Logistic regression demonstrated models predictive of D3 SA-AKI risk performed optimally among patients with high- or intermediate-PERSEVERE-II risk strata. A 6 terminal node CART model restricted to this subgroup of patients had an area under the receiver operating characteristic curve (AUROC) 0.90 and 0.77 upon tenfold cross-validation in the derivation cohort to distinguish those with and without D3 SA-AKI SCr and high specificity. The newly derived model performed modestly in a unique set of patients (n = 224), 84 of whom were deemed high- or intermediate-PERSEVERE-II risk, to distinguish those patients with high versus low risk of D3 SA-AKI SCr. CONCLUSIONS Endothelial dysfunction biomarkers are independently associated with risk of severe SA-AKI. Pending validation, incorporation of endothelial biomarkers may facilitate prognostic and predictive enrichment for selection of therapeutics in future clinical trials among critically ill children.

Abstract
Introduction Post-ICU admission cumulative positive fluid balance (PFB) is associated with increased mortality among critically ill patients. We sought to test whether this risk varied across biomarker-based risk strata upon adjusting for illness severity, presence of severe acute kidney injury (AKI), and use of renal replacement therapy (CRRT) in pediatric septic shock. Design Ongoing multi-center prospective observational cohort. Setting Thirteen pediatric ICUs in the United States (2003-2023). Patients Six hundred and eighty-one children with septic shock. Interventions None. Measurements and Main Results Cumulative percent positive fluid balance between day 1-7 (Day 1-7%PFB) was determined. Primary outcome of interest was complicated course defined as death or persistence of ≥ 2 organ dysfunctions by day 7. PERSEVERE-II biomarkers were used to assign mortality probability and categorize patients into high (n = 91), intermediate (n = 134), and low (n = 456) mortality risk strata. Cox proportional hazard regression models with adjustment for PERSEVERE-II mortality probability, presence of sepsis associated acute kidney injury (SA-AKI) on Day 3, and any use of CRRT, demonstrated that time-dependent variable Day 1-7%PFB was independently associated with increased hazard of complicated course in the cohort. Risk stratified analyses revealed that each 10% increase in Day 1-7%PFB was independently associated with increased hazard of complicated course among patients with high mortality risk strata (adj HR of 1.24 (95%CI: 1.08-1.42), p = 0.002), but not among those categorized as intermediate- or low- mortality risk. Conclusions Our data demonstrate the independent influence of cumulative %PFB on the risk of complicated course. Contrary to our previous report, this risk was largely driven by patients categorized as having a high-mortality risk based on PERSEVERE-II biomarkers. Further research is necessary to determine whether this subset of patients may benefit from targeted deployment of restrictive fluid management or early initiation of de-escalation therapies upon resolution of shock.

Abstract
BACKGROUND Sepsis is associated with significant mortality. Yet, there are no efficacious therapies beyond antibiotics. PCSK9 loss-of-function (LOF) and inhibition, through enhanced low-density lipoprotein receptor (LDLR) mediated endotoxin clearance, holds promise as a potential therapeutic approach among adults. In contrast, we have previously demonstrated higher mortality in the juvenile host. Given the potential pleiotropic effects of PCSK9 on the endothelium, beyond canonical effects on serum lipoproteins, both of which may influence sepsis outcomes, we sought to test the influence of PCSK9 LOF genotype on endothelial dysfunction. METHODS Secondary analyses of a prospective observational cohort of pediatric septic shock. Genetic variants of PCSK9 and LDLR genes, serum PCSK9, and lipoprotein concentrations were determined previously. Endothelial dysfunction markers were measured in day 1 serum. We conducted multivariable linear regression to test the influence of PCSK9 LOF genotype on endothelial markers, adjusted for age, complicated course, and low- and high-density lipoproteins (LDL and HDL). Causal mediation analyses to test impact of select endothelial markers on the association between PCSK9 LOF genotype and mortality. Juvenile Pcsk9 null and wildtype mice were subject to cecal slurry sepsis and endothelial markers were quantified. RESULTS A total of 474 patients were included. PCSK9 LOF was associated with several markers of endothelial dysfunction, with strengthening of associations after exclusion of those homozygous for the rs688 LDLR variant that renders it insensitive to PCSK9. Serum PCSK9 was not correlated with endothelial dysfunction. PCSK9 LOF influenced concentrations of Angiopoietin-1 (Angpt-1) upon adjusting for potential confounders including lipoprotein concentrations, with false discovery adjusted p value of 0.042 and 0.013 for models that included LDL and HDL, respectively. Causal mediation analysis demonstrated that the effect of PCSK9 LOF on mortality was mediated by Angpt-1 (p = 0.0008). Murine data corroborated these results with lower Angpt-1 and higher soluble thrombomodulin among knockout mice with sepsis relative to the wildtype. CONCLUSIONS We present genetic and biomarker association data that suggest a potential direct role of the PCSK9-LDLR pathway on Angpt-1 in the developing host with septic shock and warrant external validation. Further, mechanistic studies on the role of PCSK9-LDLR pathway on vascular homeostasis may lead to the development of pediatric-specific sepsis therapies.

Abstract
Introduction Cystitis and pyelonephritis are common bacterial infections in infants and children, and initial treatment is usually empirical. Antimicrobial stewardship advocates using narrow-spectrum antibiotics with consideration for local resistance patterns. Narrow-spectrum antibiotic use is critical in addressing the global issue of bacterial antimicrobial resistance, associated with approximately 5 million annual deaths. Methods The antimicrobial stewardship committee developed a guideline for diagnosing and managing urinary tract infections and distributed it to all primary care providers. A standardized order set provided clinical decision support regarding appropriate first-line antibiotic therapy. A chief complaint of dysuria prompted the use of the order set. Prescription rates for the most common antimicrobials were tracked on a control chart. Results From March 2018 through March 2020, there were 4,506 antibiotic prescriptions for urinary tract infections. Utilization of the recommended first-line therapy, cephalexin, increased from 27.5% to 74.8%. Over the same period, trimethoprim-sulfamethoxazole, no longer recommended due to high local resistance, decreased from 31.8% to 8.1%. Providers have maintained these prescribing patterns since the conclusion of the project. Conclusion Using clinical decision support as a standardized order set can sustainably improve the use of first-line antimicrobials for treating pediatric urinary tract infections.

Abstract
Healthcare institutions are placing greater emphasis on equitable care. To accurately track and validate equity metrics, Akron Children's Hospital evaluated how key fields are collected, analyzed, and visualized throughout the organization. Standardized recommendations in this area vary, and this investigation provided specific ways to advance analytics in this field. In addition, the technical infrastructure needed a comprehensive evaluation to increase confidence in using demographic data. Methods First, we reviewed how staff are trained to collect data at registration. Next, the electronic health record team standardized race and ethnicity fields with federal definitions. We found that fields were not consistently accessible across reporting tools. However, when present, all fields are sourced from the same electronic health record field. Finally, 6 months of encounters were analyzed and validated, with limitations to a seldom-populated Race 2 field. Results We compared data, including and excluding null values, to provide concise recommendations for standard visualizations. We uncovered many consistencies and a few inconsistencies that informed the next steps. Conclusions The results informed 7 recommendations to align Akron Children's Hospital's advancement in analytics for health equity data: standardize race and ethnicity fields across all reporting tools, add Child Opportunity Index 2.0 to the enterprise data warehouse, utilize data at the time of the patient's encounter, include null fields (patient refused, unknown, and not specified) in analysis, increase reporting capabilities for social determinants of health (SDOH), standardize multiracial data visualizations, and optimize reliable upstream data collection to increase reliability for all health equity measures.

Abstract
Background: Sepsis is associated with significant mortality, yet there are no efficacious therapies beyond antibiotics and supportive care. In adult sepsis studies, PCSK9 loss-of-function (LOF) and inhibition has shown therapeutic promise, likely through enhanced low-density lipoprotein receptor (LDLR) mediated endotoxin clearance. In contrast, we previously demonstrated higher mortality in septic juvenile hosts with PCSK9 LOF. In addition to direct influence on serum lipoprotein levels, PCSK9 likely exerts pleiotropic effects on vascular endothelium. Both mechanisms may influence sepsis outcomes. We sought to test the influence of PCSK9 LOF genotype on endothelial dysfunction in pediatric sepsis. Methods: Secondary analyses of a prospective observational cohort of pediatric septic shock. Single nucleotide polymorphisms of PCSK9 and LDLR genes were assessed. Serum PCSK9, lipoprotein, and endothelial marker concentrations were measured. Multivariable linear regression tested the influence of PCSK9 LOF genotype on endothelial markers, adjusted for age, complicated course, and low- and high-density lipoproteins (LDL and HDL). Causal mediation analyses assessed impact of select endothelial markers on the association between PCSK9 LOF genotype and mortality. Juvenile Pcsk9 null and wildtype mice were subject to cecal slurry sepsis and endothelial markers were quantified. Results: 474 patients were included. PCSK9 LOF was associated with several markers of endothelial dysfunction, with strengthening of associations after exclusion of patients homozygous for the rs688 LDLR variant that renders it insensitive to PCSK9. Serum PCSK9 levels did not correlate with endothelial dysfunction. PCSK9 LOF significantly influenced concentrations of Angiopoietin-1 (Angpt-1) and Vascular Cell Adhesion Molecule-1 (VCAM-1). However, upon adjusting for LDL and HDL, PCSK9 LOF remained significantly associated with low Angpt-1 alone. Causal Mediation Analysis demonstrated that the effect of PCSK9 LOF on mortality was partially mediated by Angpt-1 (p=0.0008). Murine data corroborated these results with lower Angpt-1 and higher soluble thrombomodulin among knockout mice with sepsis relative to the wildtype. Conclusions: PCSK9 LOF independently influences serum Angpt-1 levels in pediatric septic shock. Angpt-1 likely contributes mechanistically to the effect of PCSK9 LOF on mortality in juvenile hosts. Mechanistic studies on the role of PCSK9-LDLR pathway on vascular homeostasis may lead to the development of novel pediatric-specific sepsis therapies.

Abstract
Background Multiple organ dysfunction syndrome (MODS) is a critical driver of sepsis morbidity and mortality in children. Early identification of those at risk of death and persistent organ dysfunctions is necessary to enrich patients for future trials of sepsis therapeutics. Here, we sought to integrate endothelial and PERSEVERE biomarkers to estimate the composite risk of death or organ dysfunctions on day 7 of septic shock. Methods We measured endothelial dysfunction markers from day 1 serum among those with existing PERSEVERE data. TreeNet® classification model was derived incorporating 22 clinical and biological variables to estimate risk. Based on relative variable importance, a simplified 6-biomarker model was developed thereafter. Results Among 502 patients, 49 patients died before day 7 and 124 patients had persistence of MODS on day 7 of septic shock. Area under the receiver operator characteristic curve (AUROC) for the newly derived PERSEVEREnce model to predict death or day 7 MODS was 0.93 (0.91–0.95) with a summary AUROC of 0.80 (0.76–0.84) upon tenfold cross-validation. The simplified model, based on IL-8, HSP70, ICAM-1, Angpt2/Tie2, Angpt2/Angpt1, and Thrombomodulin, performed similarly. Interaction between variables—ICAM-1 with IL-8 and Thrombomodulin with Angpt2/Angpt1—contributed to the models’ predictive capabilities. Model performance varied when estimating risk of individual organ dysfunctions with AUROCS ranging from 0.91 to 0.97 and 0.68 to 0.89 in training and test sets, respectively. Conclusions The newly derived PERSEVEREnce biomarker model reliably estimates risk of death or persistent organ dysfunctions on day 7 of septic shock. If validated, this tool can be used for prognostic enrichment in future pediatric trials of sepsis therapeutics. Graphical abstract ![]()

Abstract
Background Environmental contamination contributes to hospital associated infections, particularly those caused by multi-drug resistant organisms (MDRO). This study investigated bioburden presence on surfaces in a critical care center’s patient rooms following typical environmental services (EVS) practices and following intervention with hybrid hydrogen peroxide™ (HHP™) fogging. Methods Upon patient discharge, following standard cleaning or cleaning with ultraviolet (UV) light use, patient rooms were sampled by swabbing for adenosine triphosphate (ATP) and aerobic colony counts (ACC) from five preset locations. Rooms were then fogged via HHP technology using chemical indicators and Geobacillus stearothermophilus biological indicators for sporicidal validation monitoring. Following fogging, rooms were sampled again, and results were compared. Results A 98% reduction in ACC was observed after fogging as compared to post EVS practices both with and without UV light use. No statistical difference was seen when comparing cleaning to cleaning with UV light use. Methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa were identified following EVS practices and not detected following HHP fogging. ATP samples were reduced 88% by fogging application. Chemical and biological indicators confirmed correct application of HHP fogging, as seen through its achievement of a 6-log reduction of bacterial spores. Conclusion HHP fogging is a thorough and efficacious technology which, when applied to critical care patient rooms, significantly reduces bioburden on surfaces, indicating potential benefits for implementation as part of infection prevention measures.

Abstract
BACKGROUND Pediatric acute care utilization decreased dramatically during the coronavirus disease 2019 (COVID-19) pandemic. This study examined the association between the Child Opportunity Index (COI), a multidimensional neighborhood measure of childhood opportunity, and changes in acute care utilization at US pediatric hospitals during the COVID-19 pandemic compared with the previous 3 years. METHODS This observational study used administrative data across 41 US-based pediatric hospitals. Children aged 0 to 17 years with emergency department (ED) encounters during the study period were included. The COVID-19 pandemic time period (March 15, 2020-March 14, 2021) was the primary exposure. The primary outcome was the relative volume drop in ED encounters and observation/inpatient admissions through the ED by COI quintile. RESULTS Of 12 138 750 encounters, 3 705 320 (30.5%) were among the very low COI quintile. Overall, there was a 46.8% relative volume reduction in the pandemic period compared with the prepandmic period. This drop in volume occurred disproportionately among the very low COI quintile (51.1%) compared with the very high COI quintile (42.8%). The majority of clinical diagnosis groups demonstrated larger relative volume drops among the very low COI quintile. CONCLUSIONS Acute care utilization decreased the most among children from very low COI neighborhoods, narrowing previously described acute care utilization disparities. Additional study of patient perspectives on health care needs and access during this period is required to understand these changes.

Abstract
OBJECTIVES Our goal with this initiative was to reduce discharge opioid prescriptions while maintaining optimal pain management through the use of standardized pain prescribing guidelines for pediatric patients after orthopedic surgical procedures. METHODS Through analysis of established yet inconsistent prescribing practices, we created a 4-tiered guideline for pediatric orthopedic postoperative pain management prescription ordering. Following the Model for Improvement methodology including iterative plan-do-study-act cycles, the team created an electronic medical record order set to be used at discharge from the hospital. The provider compliance with this order set was monitored and analyzed over time by using provider-level and aggregate control charts. A secondary measure of opioid prescriptions (morphine milligram Eq [MME] dosage per patient) was tracked over time. The balancing measure was the analysis of unanticipated opioid prescription refills. RESULTS Greater than 90% compliance with the guidelines was achieved and sustained for 20 months. This resulted in a 54% reduction in opioids prescribed during the improvement period (baseline = 71 MME per patient; postintervention = 33 MME per patient) and has been sustained for 12 months. The percentage of unanticipated opioid prescription refills did not significantly change from the period before the institution of the guidelines and after institution of the guidelines (2017 = 3%; 2019 = 3%). CONCLUSIONS The creation of these guidelines has led to a significant reduction in the number of opioids prescribed while maintaining effective postoperative pain management.

Abstract
Introduction Sepsis-associated acute kidney injury (AKI) is a common diagnosis in children that is associated with poor outcomes. The lack of therapeutic options once present makes early identification of at-risk patients essential. The renal angina index (RAI) has been previously validated to predict severe AKI in heterogeneous populations of critically ill children. The performance of this score specifically in children with septic shock is unknown. Methods A secondary analysis of a multicenter, prospective, observational study of 379 children with septic shock to determine the ability of the RAI to predict severe AKI at day 3, and to assess for the potential need for recalibration of the RAI in this unique subset of patients. Results At the original cutoff of ≥8, the RAI predicted day 3 severe AKI with an area under the receiving operating characteristic (AUROC) curve 0.90 (95% confidence interval [CI]: 0.86 to 93), 95% sensitivity, and 54% specificity. A Youden's index identified a higher optimal cutoff of ≥20 (sensitivity 83%, specificity 80%), and day 1 platelet count <150 × 103/μl was an independent predictor of severe AKI (adjusted odds ratio: 3.2; 95% CI: 1.7 to 6.3; P < 0.001). Recalibration of the RAI to include platelet count and this new threshold restored the sensitivity of the original ≥8 threshold (95%), while improving its specificity (69%). Conclusions The RAI appears to be a sensitive and reliable tool for prediction of severe AKI in children with septic shock, although the use of a recalibrated sepsis-specific RAI using a higher cutoff and platelet count may be beneficial.

Abstract
Sepsis remains a major public health problem with no major therapeutic advances over the last several decades. The clinical and biological heterogeneity of sepsis have limited success of potential new therapies. Accordingly, there is considerable interest in developing a precision medicine approach to inform more rational development, testing, and targeting of new therapies. We previously developed the Pediatric Sepsis Biomarker Risk Model (PERSEVERE) to estimate mortality risk and proposed its use as a prognostic enrichment tool in sepsis clinical trials; prognostic enrichment selects patients based on mortality risk independent of treatment. Here, we show that PERSEVERE has excellent performance in a diverse cohort of children with septic shock with potential for use as a predictive enrichment strategy; predictive enrichment selects patients based on likely response to treatment. We demonstrate that the PERSEVERE biomarkers are reliably associated with mortality in mice challenged with experimental sepsis, thus providing an opportunity to test precision medicine strategies in the preclinical setting. Using this model, we tested two clinically feasible therapeutic strategies, guided by the PERSEVERE-based enrichment, and found that mice identified as high risk for mortality had a greater bacterial burden and could be rescued by higher doses of antibiotics. The association between higher pathogen burden and higher mortality risk was corroborated among critically ill children with septic shock. This bedside to bench to bedside approach provides proof of principle for PERSEVERE-guided application of precision medicine in sepsis.

Abstract
Rationale: Acute kidney injury (AKI), a common complication of sepsis, is associated with substantial morbidity and mortality and lacks definitive disease-modifying therapy. Early, reliable identification of at-risk patients is important for targeted implementation of renal protective measures. The updated Pediatric Sepsis Biomarker Risk Model (PERSEVERE-II) is a validated, multibiomarker prognostic enrichment strategy to estimate baseline mortality risk in pediatric septic shock.Objectives: To assess the association between PERSEVERE-II mortality probability and the development of severe, sepsis-associated AKI on Day 3 (D3 SA-AKI) in pediatric septic shock.Methods: We performed secondary analysis of a prospective observational study of children with septic shock in whom the PERSEVERE biomarkers were measured to assign a PERSEVERE-II baseline mortality risk.Measurements and Main Results: Among 379 patients, 65 (17%) developed severe D3 SA-AKI. The proportion of patients developing severe D3 SA-AKI increased directly with increasing PERSEVERE-II risk category, and increasing PERSEVERE-II mortality probability was independently associated with increased odds of severe D3 SA-AKI after adjustment for age and illness severity (odds ratio, 1.4; 95% confidence interval, 1.2-1.7; P < 0.001). Similar associations were found between increasing PERSEVERE-II mortality probability and the need for renal replacement therapy. Lower PERSEVERE-II mortality probability was independently associated with increased odds of renal recovery among patients with early AKI. A newly derived model incorporating the PERSEVERE biomarkers and Day 1 AKI status predicted severe D3 SA-AKI with an area under the received operating characteristic curve of 0.95 (95% confidence interval, 0.92-0.98).Conclusions: Among children with septic shock, the PERSEVERE biomarkers predict severe D3 SA-AKI and identify patients with early AKI who are likely to recover.

Abstract
Emergency medical services and critical care transport teams are relatively new parts of the American healthcare delivery system. Although most healthcare providers regularly interact with these groups and rely upon their almost ubiquitous availability, few know how these services developed or what sort of infrastructure currently exists to maintain them. This article provides a focused overview of the history and present practices of both emergency medical services and critical care transport teams, with a concentrated look at the implementation of these services in the pediatric population. Within this context, we also consider current challenges and future opportunities for both groups and conclude with ways to become involved in the improvement of out-of-hospital pediatric critical care.

Abstract
BACKGROUND Children admitted to the general care floor sometimes require acute escalation of care and rapid transfer (RT) to the PICU shortly after admission. In this study, we aim to investigate the characteristics of RTs and the impact RTs have on patient outcomes, including PICU length of stay (LOS), mortality, and emergency transfer defined as critical care interventions occurring within 1 hour on either side of transfer to the PICU. METHODS We conducted a 2-year, single-center, retrospective analysis including all patients admitted to the general care floor of a tertiary children's hospital that were subsequently transferred to the PICU, with attention to those transferred within 4 hours of admission, meeting criteria as RTs. Patient-level data and outcomes were tracked. Statistical summaries were stratified by RT or non-RT strata and between-strata comparisons were performed. Significant univariate factors were entered into a multivariate logistic regression model and reduced with statistical significance required for final model inclusion. RESULTS Of 450 patients with an unplanned PICU transfer, 105 (23.3%) experienced RTs. Significant factors in the reduced multivariate logistic regression model associated with decreased risk for RT were increased baseline Pediatric Overall Performance Category (P = .046) and PICU origin of admission (P = .012). RT patients had shorter PICU LOSs (2.8 vs 5.5 days, P < .001) compared with non-RT patients despite a higher rate of emergency transfer (15.2% vs 7.5%, P = .018) and no difference in mortality (P = .741). CONCLUSIONS In this study, we demonstrate RTs have an increase in emergency transfer rate but no apparent risk of increased PICU LOS or mortality.

Abstract
BACKGROUND Confirmation of endotracheal tube (ETT) tip position and timely identification and correction of malposition is an essential component of care for endotracheally intubated and mechanically ventilated children. We evaluated the ability of a prototype optoacoustic medical device to determine ETT tip position. We hypothesized that the precision of optoacoustic assessment of ETT tip position would be comparable to chest radiography. METHODS We recruited children aged newborn to 16 y who were admitted to the pediatric ICU requiring tracheal intubation and undergoing a chest radiograph for clinical purposes. After positioning each child on a chest radiograph plate, a sterile optical fiber, temporarily inserted through the ETT, emitted laser pulses perpendicular to the fiber and to the ETT, generating acoustic (ultrasound) waves in overlying tissue when the tip of the fiber passed beneath an acoustic sensor in the sternal notch. The distance from the ETT tip to the peak acoustic signal was used to calculate the distance from the ETT tip to the carina, which was compared with the same distance calculated by the radiologist reading the chest radiograph. Pearson's correlation coefficient, paired t tests, a Bland-Altman plot were used to compare the measures (P < .05 was considered statistically significant). RESULTS Twenty-six subjects were enrolled: 15 (57.7%) were male, median (interquartile range) age, weight, and height were 9 months (4-24), 9.6 kg (5.7-13.0), and 75 cm (62-90), respectively. All ETTs were cuffed (internal diameter range 3.0-5.0 mm). The relationship between optoacoustic and chest radiograph measurements was strong (r = 0.91, P < .001). Bias was 0.1 cm with narrow limits of agreement between measures (0.58 cm and 0.76 cm). CONCLUSIONS The optoacoustic prototype accurately determined ETT tip position and was comparable in precision to chest radiograph.

Abstract
BACKGROUND Adherence to guidelines for endotracheal tube (ETT) insertion depth may not be sufficient to prevent malposition or harm to the patient. To obtain an estimate of ETT malpositioning, we evaluated initial postintubation chest radiographs and hypothesized that many ETTs in multiple intubation settings would be malpositioned despite adherence to Pediatric Advanced Life Support and Neonatal Resuscitation Program guidelines. METHODS In a random subset (randomization table) of 2,000 initial chest radiographs obtained from January 1, 2009, to May 5, 2012, we recorded height, weight, age, sex, ETT inner diameter, and cm marking at the lip from the electronic health record. Chest radiographs of poor quality and with spinal or skeletal deformities were excluded. We defined adherence to Pediatric Advanced Life Support or Neonatal Resuscitation Program guidelines as the difference between predicted and actual ETT markings at the lip as ± 0.25, ± 0.50, or ± 1.0 cm for ETTs of 2.5-4, 4.5-6.0, or >6.5 mm inner diameter, respectively. We defined the proper position as the ETT tip being below the thoracic inlet (superior border of the clavicular heads) and ≥1 cm above the carina. Descriptive statistics reported demographics, guideline adherence, and malposition incidence. The chi-square test was used to assess relationships among intubation setting, malposition, and depth guideline adherence (P < .05, significant). RESULTS We reviewed 507 records, 477 of which met inclusion criteria and had sufficient data for analysis. Fifty-six percent of the subjects were male, with median (interquartile range) age 15.2 (3.4-59.4) months, and 330 ETTs (69%) were malpositioned: 39 above the thoracic inlet, and 291 < 1 cm above the carina. Of 79 ETTS (17%) that adhered to depth guidelines, 56 (74%) were malpositioned. Three-hundred seventy-three ETTs (83%) did not meet guidelines. Two-hundred sixty-four (68%) were malpositioned. The intubation setting did not influence malposition or guideline adherence (P = .54). CONCLUSIONS In infants and children, a high proportion of ETTs were malpositioned on the first postintubation chest radiograph, with little influence of guideline adherence.

Abstract
BACKGROUND The American Academy of Pediatrics Section on Transport recommends the use of portable ventilators during the transport of patients with advanced airways. We sought to identify knowledge gaps and evaluate the effectiveness of a transport ventilator competency boot camp. METHODS Electronic health records of children requiring ventilatory support during air and ground interfacility transport from January 1 through December 31, 2015, were reviewed to determine when manual ventilation was used in lieu of a portable ventilator, and simulations were constructed from commonly occurring scenarios. All registered respiratory therapists trained in air and ground critical-care transports participated. Demographic data were collected. We assessed performance on 3 facilitated simulated scenarios using a ventilator connected to a low-fidelity pediatric mannequin attached to breathing simulator. Scores were based on the participants' ability to correctly perform pre-use checks, select and optimize ventilator settings, set alarms, and complete safety checks. A 60-min interactive education intervention was conducted between the pre- and post-assessments. The pre-assessment, intervention, and post-assessment were conducted 6 weeks apart. De-identified assessments were scored, and results were shared after study completion. Descriptive statistics reported participant demographics. Paired t tests compared before and after assessments. Statistical significance was established at P < .05. RESULTS A total of 172 electronic health records were reviewed. Manual ventilation was used more frequently in toddlers requiring pressure control ventilation; noninvasive ventilation was rarely used. A total of 17 registered respiratory therapists participated; 18% were male, 41% had 6-9 years of tenure and 5 years of experience with our transport team. Completing ventilator pre-use check and engaging alarms provided the most opportunity for improvement. Improvements were greater with the use of noninvasive ventilation (P = .006) than pressure control ventilation (P = .10) and volume control ventilation use (P = .07). CONCLUSIONS Quality data were useful in identifying areas requiring knowledge and competency assessment. Re-assessment results validated the need to conduct education and competency assessment at defined intervals.

Abstract
INTRODUCTION Tracheal intubation (TI) is a lifesaving critical care skill. Failed TI attempts, however, can harm patients. Critical care transport (CCT) teams function as the first point of critical care contact for patients being transported to tertiary medical centers for specialized surgical, medical, and trauma care. The Ground and Air Medical qUality in Transport (GAMUT) Quality Improvement Collaborative uses a quality metric database to track CCT quality metric performance, including TI. We sought to describe TI among GAMUT participants with the hypothesis that CCT would perform better than other prehospital TI reports and similarly to hospital TI success. METHODS The GAMUT Database is a global, voluntary database for tracking consensus quality metric performance among CCT programs performing neonatal, pediatric, and adult transports. The TI-specific quality metrics are "first attempt TI success" and "definitive airway sans hypoxia/hypotension on first attempt (DASH-1A)." The 2015 GAMUT Database was queried and analysis included patient age, program type, and intubation success rate. Analysis included simple statistics and Pearson chi-square with Bonferroni-adjusted post hoc z tests (significance = p < 0.05 via two-sided testing). RESULTS Overall, 85,704 patient contacts (neonatal n [%] = 12,664 [14.8%], pediatric n [%] = 28,992 [33.8%], adult n [%] = 44,048 [51.4%]) were included, with 4,036 (4.7%) TI attempts. First attempt TI success was lowest in neonates (59.3%, 617 attempts), better in pediatrics (81.7%, 519 attempts), and best in adults (87%, 2900 attempts), p < 0.001. Adult-focused CCT teams had higher overall first attempt TI success versus pediatric- and neonatal-focused teams (86.9% vs. 63.5%, p < 0.001) and also in pediatric first attempt TI success (86.5% vs. 75.3%, p < 0.001). DASH-1A rates were lower across all patient types (neonatal = 51.9%, pediatric = 74.3%, adult = 79.8%). CONCLUSIONS CCT TI is not uncommon, and rates of TI and DASH-1A success are higher in adult patients and adult-focused CCT teams. TI success rates are higher in CCT than other prehospital settings, but lower than in-hospital success TI rates. Identifying factors influencing TI success among high performers should influence best practice strategies for TI.

Abstract
RATIONALE We previously derived and validated the Pediatric Sepsis Biomarker Risk Model (PERSEVERE) to estimate baseline mortality risk in children with septic shock. The PERSEVERE biomarkers are serum proteins selected from among the proteins directly related to 80 mortality risk assessment genes. The initial approach to selecting the PERSEVERE biomarkers left 68 genes unconsidered. OBJECTIVES To determine if the 68 previously unconsidered genes can improve upon the performance of PERSEVERE and to provide biological information regarding the pathophysiology of septic shock. METHODS We reduced the number of variables by determining the biological linkage of the 68 previously unconsidered genes. The genes identified through variable reduction were combined with the PERSEVERE-based mortality probability to derive a risk stratification model for 28-day mortality using classification and regression tree methodology (n = 307). The derived tree, PERSEVERE-XP, was then tested in a separate cohort (n = 77). MEASUREMENTS AND MAIN RESULTS Variable reduction revealed a network consisting of 18 mortality risk assessment genes related to tumor protein 53 (TP53). In the derivation cohort, PERSEVERE-XP had an area under the receiver operating characteristic curve (AUC) of 0.90 (95% confidence interval, 0.85-0.95) for differentiating between survivors and nonsurvivors. In the test cohort, the AUC was 0.96 (95% confidence interval, 0.91-1.0). The AUC of PERSEVERE-XP was superior to that of PERSEVERE. CONCLUSIONS PERSEVERE-XP combines protein and mRNA biomarkers to provide mortality risk stratification with possible clinical utility. PERSEVERE-XP significantly improves on PERSEVERE and suggests a role for TP53-related cellular division, repair, and metabolism in the pathophysiology of septic shock.

Abstract
INTRODUCTION Critical Care Transport teams use various strategies to maintain temperature sensitive drugs and equipment at optimal temperature. The purpose of this study was to examine the effectiveness of current passive refrigeration of temperature sensitive transport medications/equipment. METHODS Initially, we performed a retrospective review of transport durations. Subsequently, an experimental paradigm was created using a temperature probe inside of the transport cooler packs utilizing various configurations and initial starting temperatures with high and low "in range" temperature margins of 8°C (max) and 2°C (min). RESULTS The mean round-trip transport time was 2.5 hours and over 15% of transports last longer than 4 hours. At a starting temperature of -3.9°C, the cooler and ice pack maintained "in range" temperatures for 3 hours. When the ice pack starting temperature was -12.9°C, high temperatures excursions weren't experienced until 6 hours 55 minutes, but initially low excursions fell below for up to 3 hours. iSTAT® cartridges remained within range between 1-4 hours at cooler and ice pack starting temperature of -3.9°C. CONCLUSION The current system of passive refrigeration does not appear to be sufficient for safely storing medications or point-of-care testing equipment for our transport services. This might reveal a flaw in the existing practices around medication refrigeration in transport.

Abstract
The purpose of this study is to determine the rate of pain assessment in pediatric neonatal critical care transport (PNCCT). The GAMUT database was interrogated for an 18-month period and excluded programs with less than 10% pediatric or neonatal patient contacts and less than 3 months of any metric data reporting during the study period. We hypothesized pain assessment during PNCCT is superior to prehospital pain assessment rates, although inferior to in-hospital rates. Sixty-two programs representing 104,445 patient contacts were analyzed. A total of 21,693 (20.8%) patients were reported to have a documented pain assessment. Subanalysis identified 17 of the 62 programs consistently reporting pain assessments. This group accounted for 24,599 patients and included 7,273 (29.6%) neonatal, 12,655 (51.5%) pediatric, and 4,664 (19.0%) adult patients. Among these programs, the benchmark rate of pain assessment was 90.0%. Our analysis shows a rate below emergency medical services and consistent with published hospital rates of pain assessment. Poor rates of tracking of this metric among participating programs was noted, suggesting an opportunity to investigate the barriers to documentation and reporting of pain assessments in PNCCT and a potential quality improvement initiative.

Abstract
The temporal version of the pediatric sepsis biomarker risk model (tPERSEVERE) estimates the risk of a complicated course in children with septic shock based on biomarker changes from days 1 to 3 of septic shock. We validated tPERSEVERE performance in a prospective cohort, with an a priori plan to redesign tPERSEVERE if it did not perform well. Biomarkers were measured in the validation cohort (n = 168) and study subjects were classified according to tPERSEVERE. To redesign tPERSEVERE, the validation cohort and the original derivation cohort (n = 299) were combined and randomly allocated to training (n = 374) and test (n = 93) sets. tPERSEVERE was redesigned using the training set and CART methodology. tPERSEVERE performed poorly in the validation cohort, with an area under the curve (AUC) of 0.67 (95% CI: 0.58–0.75). Failure analysis revealed potential confounders related to clinical characteristics. The redesigned tPERSEVERE model had an AUC of 0.83 (0.79–0.87) and a sensitivity of 93% (68–97) for estimating the risk of a complicated course. Similar performance was seen in the test set. The classification tree segregated patients into two broad endotypes of septic shock characterized by either excessive inflammation or immune suppression. We prospectively tested the performance of the temporal version of the pediatric sepsis biomarker risk model (tPERSEVERE). tPERSEVERE performed poorly in the test cohort, prompting a redesign. The redesigned tPERSEVERE model performed well upon testing. The redesigned tPERSEVERE provides information regarding septic shock endotypes.
Septic shock is characterized by individual heterogeneity and it is not known who is at greatest risk of poor outcome and would thus benefit from more aggressive treatment. We designed a biomarker-based model to estimate the risk of poor outcome in children with septic shock. The model measures biomarker concentrations over the early period of disease evolution, and estimates how the biomarker changes reflect changing risk for poor outcome. The model has potential to serve as a monitor to evaluate the effectiveness of therapy in children with septic shock and may provide information regarding the biological mechanisms of septic shock.

Abstract
Introduction Experimental data from animal models of sepsis support a role for a transcription factor, nuclear erythroid-related factor 2 p45-related factor 2 (Nrf2), as a master regulator of antioxidant and detoxifying genes and intermediary metabolism during stress. Prior analysis of a pediatric septic shock transcriptomic database showed that the Nrf2 response is a top 5 upregulated signaling pathway in early pediatric septic shock. Methods We conducted a focused analysis of 267 Nrf2-linked genes using a multicenter, genome-wide expression database of 180 children with septic shock 10 years of age or younger and 53 healthy controls. The analysis involved RNA isolated from whole blood within 24 h of pediatric intensive care unit admission for septic shock and a false discovery rate of 5 %. We compared differentially expressed genes from (1) patients with septic shock and healthy controls and (2) across validated gene expression–based subclasses of pediatric septic shock (endotypes A and B) using several bioinformatic methods. Results We found upregulation of 123 Nrf2-linked genes in children with septic shock. The top gene network represented by these genes contained primarily enzymes with oxidoreductase activity involved in cellular lipid metabolism that were highly connected to the peroxisome proliferator activated receptor and the retinoic acid receptor families. Endotype A, which had higher organ failure burden and mortality, exhibited a greater downregulation of Nrf2-linked genes than endotype B, with 92 genes differentially regulated between endotypes. Conclusions Our findings indicate that Nrf2-linked genes may contribute to alterations in oxidative signaling and intermediary metabolism in pediatric septic shock.

Abstract
The heat shock response, also frequently referred to as the stress response, is an ancient, highly conserved, endogenous cellular defense mechanism characterized by the rapid upregulation of a specific class of proteins known collectively as heat shock proteins, or stress proteins. The 70 kDa family of heat shock proteins are highly inducible and have been shown to possess important immunomodulatory effects in both the intracellular and extracellular compartments. In the current prospective translational study, we measured extracellular (i.e. plasma) levels of heat shock protein 72 (Hsp72) in 49 children undergoing cardiopulmonary bypass (CPB) for either palliation or repair of congenital heart disease. There was a significant and transient increase (less than 24 h) in extracellular Hsp72 levels following CPB. Extracellular Hsp72 levels significantly correlated with levels of the pro-inflammatory cytokines interleukin (IL)-6 and IL-8, as well as the anti-inflammatory cytokine, IL-10. In addition, plasma Hsp72 levels correlated with troponin-I levels, a marker of myocardial injury. Increased extracellular Hsp72 levels at 6 h following CPB were independently associated with increased length of stay in the cardiac intensive care unit. Importantly, the source of extracellular Hsp72 does not appear to be cardiomyocytes. However, the mechanism of release and clinical relevance of the increase in extracellular Hsp72 need to be further delineated.

Abstract
RATIONALE Using microarray data, we previously identified gene expression-based subclasses of septic shock with important phenotypic differences. The subclass-defining genes correspond to adaptive immunity and glucocorticoid receptor signaling. Identifying the subclasses in real time has theranostic implications, given the potential for immune-enhancing therapies and controversies surrounding adjunctive corticosteroids for septic shock. OBJECTIVES To develop and validate a real-time subclassification method for septic shock. METHODS Gene expression data for the 100 subclass-defining genes were generated using a multiplex messenger RNA quantification platform (NanoString nCounter) and visualized using gene expression mosaics. Study subjects (n = 168) were allocated to the subclasses using computer-assisted image analysis and microarray-based reference mosaics. A gene expression score was calculated to reduce the gene expression patterns to a single metric. The method was tested prospectively in a separate cohort (n = 132). MEASUREMENTS AND MAIN RESULTS The NanoString-based data reproduced two septic shock subclasses. As previously, one subclass had decreased expression of the subclass-defining genes. The gene expression score identified this subclass with an area under the curve of 0.98 (95% confidence interval [CI95] = 0.96-0.99). Prospective testing of the subclassification method corroborated these findings. Allocation to this subclass was independently associated with mortality (odds ratio = 2.7; CI95 = 1.2-6.0; P = 0.016), and adjunctive corticosteroids prescribed at physician discretion were independently associated with mortality in this subclass (odds ratio = 4.1; CI95 = 1.4-12.0; P = 0.011). CONCLUSIONS We developed and tested a gene expression-based classification method for pediatric septic shock that meets the time constraints of the critical care environment, and can potentially inform therapeutic decisions.

Abstract
BACKGROUND There are nearly 200,000 US infants/children transported annually for specialty care and there are no published best practices in transport intubation. OBJECTIVE Respiratory interventions are a priority in pediatric and neonatal critical care transport (PNCCT). A recent Delphi study identified intubation performance as an important PNCCT quality metric, though data are insufficient. The objective of the study is to determine multi-center rates of first attempt intubation success in pediatric/neonatal transport and identify practice processes associated with higher performing centers. METHODS Retrospective chart review where data was collected from the 9 participating centers over a 6-month period from January-June 2013. Data describing intubation training and practices were gathered using SurveyMonkey® (Palo Alto, CA). Data were tabulated in Microsoft Excel (Redmond, WA) and analyzed using descriptive statistics. Through the determination of 1(st) intubation success rate across multiple pediatric/neonatal critical care transport programs, we hypothesized that the features of higher and lower performing centers can be identified to inform practice. RESULTS 9 of 14 invited institutions participated. The median (IQR) 6-month transport volume for neonates(neo) was 289(35-646) and pediatric (ped) 510(122-831). On average, 7%(+/-3.0) of neo and 1.6%(+/-0.7) of ped transport patients required intubation. Individual centers had their initial success rate calculated and a 95% confidence interval was determined for those centers satisfying the np > 5 and n(1-p) > 5 sample size requirement for normality assumption of proportions. Since the overall success rate was 64%, it was determined that n = 14 initial intubation attempts would be the minimum number needed per center in order to fulfill the sample size requirement for normality assumption. Centers whose 95% confidence interval did not contain the initial overall success rate were identified. CONCLUSION This represents the first multi-center neo/ped intubation dataset in PNCCT. First attempt intubation success lags behind reported anesthesia intubation rates but parallels pediatric emergency department intubation success rates. Training and operational processes are variable in PNCCT, though top performing teams require live-patient intubation success to achieve initial intubation competency.

Abstract
OBJECTIVE Family-centered care (FCC) in medicine highlights mutually beneficial partnerships among providers, patients, and families. In the field of specialty pediatric critical care transport (SPCCT), FCC includes family presence during transport. We sought to describe family presence and family/staff perspectives of FCC in transport. METHODS This institutional review board-approved study established family presence rates among 5 SPCCT teams. At the top-performing family presence team, parents of transported children were interviewed. A staff survey measured perspectives on FCC using SurveyMonkey (Palo Alto, CA). Statistical tests including chi-square and Fisher exact tests for comparative data were applied using SPSSv17.0 software (SPSS Inc, Chicago, IL). RESULTS The cohort-wide range of family presence was 23% to 66%. Parents were 4 times more likely to accompany their child if transported by ground versus air (ground: 26 [59%] vs. air: 6 [26%]). Sex, race, travel distance from referral hospital, and child's age did not influence the rate of family accompaniment. Most staff (76%) received education on FCC. CONCLUSIONS This study informs how transport factors and parent/staff perceptions influence parental presence on transport at a single center. Opportunities to optimize transport FCC include defining protocols for ground and air transport, establishing a more welcoming attitude toward parents, and designing an FCC educational module specific for transport staff.

Abstract
Introduction Increasing evidence supports a role for mitochondrial dysfunction in organ injury and immune dysregulation in sepsis. Although differential expression of mitochondrial genes in blood cells has been reported for several diseases in which bioenergetic failure is a postulated mechanism, there are no data about the blood cell mitochondrial transcriptome in pediatric sepsis. Methods We conducted a focused analysis using a multicenter genome-wide expression database of 180 children ≤10 years of age with septic shock and 53 healthy controls. Using total RNA isolated from whole blood within 24 hours of PICU admission for septic shock, we evaluated 296 nuclear-encoded mitochondrial genes using a false discovery rate of 1%. A series of bioinformatic approaches were applied to compare differentially expressed genes across previously validated gene expression-based subclasses (groups A, B, and C) of pediatric septic shock. Results In total, 118 genes were differentially regulated in subjects with septic shock compared to healthy controls, including 48 genes that were upregulated and 70 that were downregulated. The top scoring canonical pathway was oxidative phosphorylation, with general downregulation of the 51 genes corresponding to the electron transport system (ETS). The top two gene networks were composed primarily of mitochondrial ribosomal proteins highly connected to ETS complex I, and genes encoding for ETS complexes I, II, and IV that were highly connected to the peroxisome proliferator activated receptor (PPAR) family. There were 162 mitochondrial genes differentially regulated between groups A, B, and C. Group A, which had the highest maximum number of organ failures and mortality, exhibited a greater downregulation of mitochondrial genes compared to groups B and C. Conclusions Based on a focused analysis of a pediatric septic shock transcriptomic database, nuclear-encoded mitochondrial genes were differentially regulated early in pediatric septic shock compared to healthy controls, as well as across genotypic and phenotypic distinct pediatric septic shock subclasses. The nuclear genome may be an important mechanism contributing to alterations in mitochondrial bioenergetic function and outcomes in pediatric sepsis.

Abstract
Background The potential benefits of corticosteroids for septic shock may depend on initial mortality risk. Objective We determined associations between corticosteroids and outcomes in children with septic shock who were stratified by initial mortality risk. Methods We conducted a retrospective analysis of an ongoing, multi-center pediatric septic shock clinical and biological database. Using a validated biomarker-based stratification tool (PERSEVERE), 496 subjects were stratified into three initial mortality risk strata (low, intermediate, and high). Subjects receiving corticosteroids during the initial 7 days of admission (n = 252) were compared to subjects who did not receive corticosteroids (n = 244). Logistic regression was used to model the effects of corticosteroids on 28-day mortality and complicated course, defined as death within 28 days or persistence of two or more organ failures at 7 days. Results Subjects who received corticosteroids had greater organ failure burden, higher illness severity, higher mortality, and a greater requirement for vasoactive medications, compared to subjects who did not receive corticosteroids. PERSEVERE-based mortality risk did not differ between the two groups. For the entire cohort, corticosteroids were associated with increased risk of mortality (OR 2.3, 95% CI 1.3–4.0, p = 0.004) and a complicated course (OR 1.7, 95% CI 1.1–2.5, p = 0.012). Within each PERSEVERE-based stratum, corticosteroid administration was not associated with improved outcomes. Similarly, corticosteroid administration was not associated with improved outcomes among patients with no comorbidities, nor in groups of patients stratified by PRISM. Conclusions Risk stratified analysis failed to demonstrate any benefit from corticosteroids in this pediatric septic shock cohort.

Abstract
Abstract Objective. Nearly 200,000 pediatric and neonatal transports occur in the United States each year with some patients requiring tracheal intubation. First-pass intubation rates in both pediatric and adult transport literature are variable as are the factors that influence intubation success. This study sought to determine risk factors for failed tracheal intubation in neonatal and pediatric transport. Methods. A retrospective chart review was performed over a 2.5-year period. Data were collected from a hospital-based neonatal/pediatric critical care transport team that transports 2,500 patients annually, serving 12,000 square miles. Patients were eligible if they were transported and tracheally intubated by the critical care transport team. Patients were categorized into two groups for data analysis: (1) no failed intubation attempts and (2) at least one failed intubation attempt. Data were tabulated using Epi Info Version 3.5.1 and analyzed using SPSSv17.0. Results. A total of 167 patients were eligible for enrollment and were cohorted by age (48% pediatric versus 52% neonatal). Neonates were more likely to require multiple attempts at intubation when compared to the pediatric population (69.6% versus 30.4%, p = 0.001). Use of benzodiazepines and neuromuscular blockade was associated with increased successful first attempt intubation rates (p = 0.001 and 0.008, respectively). Use of opiate premedication was not associated with first-attempt intubation success. The presence of comorbid condition(s) was associated with at least one failed intubation attempt (p = 0.006). Factors identified with increasing odds of at least one intubation failure included, neonatal patients (OR 3.01), tracheal tube size ≤ 2.5 mm (OR 3.78), use of an uncuffed tracheal tube (OR 6.85), and the presence of a comorbid conditions (OR 2.64). Conclusions. There were higher rates of tracheal intubation failure in transported neonates when compared to pediatric patients. This risk may be related to the lack of benzodiazepine and neuromuscular blocking agents used to facilitate intubation. The presence of a comorbid condition is associated with a higher risk of tracheal intubation failure.

Abstract
BACKGROUND AND OBJECTIVE Patient handoffs in health care require transfer of information, responsibility, and authority between providers. Suboptimal patient handoffs pose a serious safety risk. Studies demonstrating the impact of improved patient handoffs on care failures are lacking. The primary objective of this study was to evaluate the effect of a multihospital collaborative designed to decrease handoff-related care failures. METHODS Twenty-three children's hospitals participated in a quality improvement collaborative aimed at reducing handoff-related care failures. The improvement was guided by evidence-based recommendations regarding handoff intent and content, standardized handoff tools/methods, and clear transition of responsibility. Hospitals tailored handoff elements to locally important handoff types. Handoff-related care failures were compared between baseline and 3 intervention periods. Secondary outcomes measured compliance to specific change package elements and balancing measure of staff satisfaction. RESULTS Twenty-three children's hospitals evaluated 7864 handoffs over the 12-month study period. Handoff-related care failures decreased from baseline (25.8%) to the final intervention period (7.9%) (P < .05). Significant improvement was observed in every handoff type studied. Compliance to change package elements improved (achieving a common understanding about the patient from 86% to 96% [P < .05]; clear transition of responsibility from 92% to 96% [P < .05]; and minimized interruptions and distractions from 84% to 90% [P < .05]) as did overall satisfaction with the handoff (from 55% to 70% [P < .05]). CONCLUSIONS Implementation of a standardized evidence-based handoff process across 23 children's hospitals resulted in a significant decrease in handoff-related care failures, observed over all handoff types. Compliance to critical components of the handoff process improved, as did provider satisfaction.

Abstract
RATIONALE Corticosteroids are prescribed commonly for patients with septic shock, but their use remains controversial and concerns remain regarding side effects. OBJECTIVES To determine the effect of adjunctive corticosteroids on the genomic response of pediatric septic shock. METHODS We retrospectively analyzed an existing transcriptomic database of pediatric septic shock. Subjects receiving any formulation of systemic corticosteroids at the time of blood draw for microarray analysis were classified in the septic shock corticosteroid group. We compared normal control subjects (n = 52), a septic shock no corticosteroid group (n = 110), and a septic shock corticosteroid group (n = 70) using analysis of variance. Genes differentially regulated between the no corticosteroid group and the corticosteroid group were analyzed using Ingenuity Pathway Analysis. MEASUREMENTS AND MAIN RESULTS The two study groups did not differ with respect to illness severity, organ failure burden, mortality, or mortality risk. There were 319 gene probes differentially regulated between the no corticosteroid group and the corticosteroid group. These genes corresponded predominately to adaptive immunity-related signaling pathways, and were down-regulated relative to control subjects. Notably, the degree of down-regulation was significantly greater in the corticosteroid group, compared with the no corticosteroid group. A similar pattern was observed for genes corresponding to the glucocorticoid receptor signaling pathway. CONCLUSIONS Administration of corticosteroids in pediatric septic shock is associated with additional repression of genes corresponding to adaptive immunity. These data should be taken into account when considering the benefit to risk ratio of adjunctive corticosteroids for septic shock.

Abstract
Background PERSEVERE is a risk model for estimating mortality probability in pediatric septic shock, using five biomarkers measured within 24 hours of clinical presentation. Objective Here, we derive and test a temporal version of PERSEVERE (tPERSEVERE) that considers biomarker values at the first and third day following presentation to estimate the probability of a “complicated course”, defined as persistence of ≥2 organ failures at seven days after meeting criteria for septic shock, or death within 28 days. Methods Biomarkers were measured in the derivation cohort (n = 225) using serum samples obtained during days 1 and 3 of septic shock. Classification and Regression Tree (CART) analysis was used to derive a model to estimate the risk of a complicated course. The derived model was validated in the test cohort (n = 74), and subsequently updated using the combined derivation and test cohorts. Results A complicated course occurred in 23% of the derivation cohort subjects. The derived model had a sensitivity for a complicated course of 90% (95% CI 78–96), specificity was 70% (62–77), positive predictive value was 47% (37–58), and negative predictive value was 96% (91–99). The area under the receiver operating characteristic curve was 0.85 (0.79–0.90). Similar test characteristics were observed in the test cohort. The updated model had a sensitivity of 91% (81–96), a specificity of 70% (64–76), a positive predictive value of 47% (39–56), and a negative predictive value of 96% (92–99). Conclusions tPERSEVERE reasonably estimates the probability of a complicated course in children with septic shock. tPERSEVERE could potentially serve as an adjunct to physiological assessments for monitoring how risk for poor outcomes changes during early interventions in pediatric septic shock.

Abstract
OBJECTIVE We sought to describe a single center's experience with specialized critical care transport from non-hospital settings, including primary care offices and urgent care centers. We hypothesized that the majority of patients will require procedures outside the scope of practice of most EMS providers and will be better served by specialized pediatric critical care transport (SPCCT) teams. METHODS This study sought to retrospectively evaluate instances where children (0-18 years old) were transported by our SPCCT team from nonhospital settings, including primary care offices and urgent care centers, in 2009 and 2010. Data were extracted from a customized database and appropriate statistical tests were applied, including Fisher's exact test for categorical comparisons and Mann-Whitney U test for non-parametric data comparisons. RESULTS Fifty-two patients were included. Most of the children were transported for respiratory distress (78%), and many were treated with albuterol (42%) and steroids (42%) prior to the SPCCT team arrival. The most common interventions performed by the SPCCT team were obtaining IV access and administering IV fluid boluses; 4 (7.7%) patients required advanced critical care treatments unique to SPCCT. Most patients (n = 34; 65%) were directly admitted to the general care floor, but a high number of patients (n = 12; 23%; PICU = 11, NICU = 1) required pediatric or neonatal intensive care unit admission. Only 3 patients (5.7%) were discharged home without hospital admission. For the 11 patients admitted to the PICU, the median length of stay (LOS) was 2.5 days (IQR 0.14-13.2). All patients survived to hospital discharge with an additional hospital LOS of 1.3 days (IQR 0.2-6.7). Patients were billed for these critical care transports an average of $2,660.14 ± $940. CONCLUSION Our small cohort demonstrates infrequent application of advanced critical care interventions beyond those provided by the referring primary care office or urgent care centers. This supports the practice of SPCCT teams providing transport services for select critically ill children at primary care offices and urgent care centers, but not as a standard practice for most pediatric patients in these settings.

Abstract
BACKGROUND We previously derived and validated a risk model to estimate mortality probability in children with septic shock (PERSEVERE; PEdiatRic SEpsis biomarkEr Risk modEl). PERSEVERE uses five biomarkers and age to estimate mortality probability. After the initial derivation and validation of PERSEVERE, we combined the derivation and validation cohorts (n = 355) and updated PERSEVERE. An important step in the development of updated risk models is to test their accuracy using an independent test cohort. OBJECTIVE To test the prognostic accuracy of the updated version PERSEVERE in an independent test cohort. METHODS Study subjects were recruited from multiple pediatric intensive care units in the United States. Biomarkers were measured in 182 pediatric subjects with septic shock using serum samples obtained during the first 24 hours of presentation. The accuracy of PERSEVERE 28-day mortality risk estimate was tested using diagnostic test statistics, and the net reclassification improvement (NRI) was used to test whether PERSEVERE adds information to a physiology-based scoring system. RESULTS Mortality in the test cohort was 13.2%. Using a risk cut-off of 2.5%, the sensitivity of PERSEVERE for mortality was 83% (95% CI 62-95), specificity was 75% (68-82), positive predictive value was 34% (22-47), and negative predictive value was 97% (91-99). The area under the receiver operating characteristic curve was 0.81 (0.70-0.92). The false positive subjects had a greater degree of organ failure burden and longer intensive care unit length of stay, compared to the true negative subjects. When adding PERSEVERE to a physiology-based scoring system, the net reclassification improvement was 0.91 (0.47-1.35; p<0.001). CONCLUSIONS The updated version of PERSEVERE estimates mortality probability reliably in a heterogeneous test cohort of children with septic shock and provides information over and above a physiology-based scoring system.
