Objectives: We sought to improve utilization of a sepsis care bundle and decrease 3- and 30- day sepsis-attributable mortality, as well as determine which care elements of a sepsis bundle are associated with improved outcomes.
Methods: Children's Hospital Association formed a QI collaborative to Improve Pediatric Sepsis Outcomes (IPSO) (January 2017-March 2020 analyzed here). IPSO Suspected Sepsis (ISS) patients were those without organ dysfunction where the provider "intended to treat" sepsis.
Objectives: To examine how timing of the first outpatient mental health (MH) visit after a pediatric firearm injury varies by sociodemographic and clinical characteristics.
Methods: We retrospectively studied children aged 5 to 17 years with a nonfatal firearm injury from 2010 to 2018 using the IBM Watson MarketScan Medicaid database. Logistic regression estimated the odds of MH service use in the 6 months after injury, adjusted for sociodemographic and clinical characteristics.
Importance: Government and commercial health insurers have recently enacted policies to discourage nonemergent emergency department (ED) visits by reducing or denying claims for such visits using retrospective claims algorithms. Low-income Black and Hispanic pediatric patients often experience worse access to primary care services necessary for preventing some ED visits, raising concerns about the uneven impact of these policies.
Objective: To estimate potential racial and ethnic disparities in outcomes of Medicaid policies for reducing ED professional reimbursement based on a retrospective diagnosis-based claims algorithm.
Background: Hospitalization costs for treatment of hemodialysis (HD) catheter-associated blood stream infections (CA-BSI) in adults are high. No studies have evaluated hospitalization costs for HD CA-BSI in children or identified factors associated with high-cost hospitalizations.
Methods: We analyzed 160 HD CA-BSIs from the Standardizing Care to Improve Outcomes in Pediatric End-stage Kidney Disease (SCOPE) collaborative database linked to hospitalization encounters in the Pediatric Health Information System (PHIS) database.
Introduction: Firearm injuries are a leading cause of morbidity among children, but data on healthcare utilization and expenditures after injury are limited. This study sought to analyze healthcare encounters and expenditures for 2 years after a nonfatal firearm injury.
Methods: A retrospective cohort study was conducted between 2020 and 2022 of children aged 0-18 years with International Classification of Diseases, Ninth Revision/ICD-10 diagnosis codes for firearm injury from 2010 to 2016 in the Medicaid MarketScan claims database.
Objective: To compare new mental health diagnoses (NMHD) in children after a firearm injury versus following a motor vehicle collision (MVC).
Background: A knowledge gap exists regarding childhood mental health diagnoses following firearm injuries, notably in comparison to other forms of traumatic injury.
Methods: We utilized Medicaid MarketScan claims (2010-2016) to conduct a matched case-control study of children ages 3 to 17 years.
Importance: Lower rates of diagnostic imaging have been observed among Black children compared with White children in pediatric emergency departments. Although the racial composition of the pediatric population served by each hospital differs, it is unclear whether this is associated with overall imaging rates at the hospital level, and in particular how it may be associated with the difference in imaging rates between Black and White children at a given hospital.
Objective: To examine the association between the diversity of the pediatric population seen at each pediatric ED and variation in diagnostic imaging.
Study Objective: To determine whether the receipt of more than or equal to 30 mL/kg of intravenous fluid in the first hour after emergency department (ED) arrival is associated with sepsis-attributable mortality among children with hypotensive septic shock.
Methods: This is a retrospective cohort study set in 57 EDs in the Improving Pediatric Sepsis Outcomes quality improvement collaborative. Patients less than 18 years of age with hypotensive septic shock who received their first intravenous fluid bolus within 1 hour of arrival at the ED were propensity-score matched for probability of receiving more than or equal to 30 mL/kg in the first hour.
Background: Previously few means existed to broadly examine variability across conditions/practices within or between hospitals for common pediatric conditions.
Objective: Our objective was to develop a novel empiric measure of variation in care and test its association with patient-centered outcomes.
Designs: We conducted a retrospective cohort study of children hospitalized from January 2016 to December 2018 using the Pediatric Hospital Information Systems database.
Background: There has been growing support for the adoption of telehealth (TH) services in pediatric populations. Children on chronic peritoneal dialysis (PD) represent a vulnerable population that could benefit from increased use of TH. The COVID-19 pandemic prompted rapid adoption of TH services in the population among pediatric centers participating in The Children's Hospital Association's Standardizing Care to Improve Outcomes in Pediatric ESKD (SCOPE) Collaborative.

The Standardizing Care to Improve Outcomes in Pediatric End-Stage Kidney Disease (SCOPE) Collaborative is a quality-improvement initiative aimed at reducing dialysis-associated infections by implementing standardized care practices. This study describes patient-level risk factors for catheter-associated bloodstream infections (CA-BSIs) and examines the association between dialysis center-level compliance with standardized practices and risk of CA-BSI.
View Article and Find Full Text PDFImportance: The scope of low-value care in children's hospitals is poorly understood.
Objective: To develop and apply a calculator of hospital-based pediatric low-value care to estimate prevalence and cost of low-value services.
Design, Setting, And Participants: This cross-sectional study developed and applied a calculator of hospital-based pediatric low-value care to estimate the prevalence and cost of low-value services among 1 011 950 encounters reported in 49 US children's hospitals contributing to the Pediatric Health Information System (PHIS) database.
Background: Studies regarding hemodialysis (HD) arteriovenous fistula (AVF) cannulation in adults indicate a higher risk of infection with the buttonhole (BH) technique compared to the rope-ladder (RL) technique. Pediatric data on this issue is sparse.
Methods: We compared infection rates within the Standardizing Care to Improve Outcomes in Pediatric End stage kidney disease (SCOPE) centers performing BH cannulation versus RL cannulation of AVF.
Background: A 56 US hospital collaborative, Improving Pediatric Sepsis Outcomes, has developed variables, metrics and a data analysis plan to track quality improvement (QI)-based patient outcomes over time. Improving Pediatric Sepsis Outcomes expands on previous pediatric sepsis QI efforts by improving electronic data capture and uniformity across sites.
Methods: An expert panel developed metrics and corresponding variables to assess improvements across the care delivery spectrum, including the emergency department, acute care units, hematology and oncology, and the ICU.
Background: In its first 3 years, the Standardizing Care to Improve Outcomes in Pediatric End Stage Renal Disease (SCOPE) Collaborative demonstrated a statistically significant increase in the likelihood of compliance with a standardized follow-up care bundle and a significant reduction in peritonitis. We sought to determine if compliance with care bundles and low peritonitis rates could be sustained in centers continuously participating for 84 months.
Methods: Centers that participated from collaborative launch through the 84-month study period and provided pre-launch peritonitis rates were included.
