Firearm Injury Risk Prediction Among Children Transported by 9-1-1 Emergency Medical Services: A Machine Learning Analysis.

Objective: Among children transported by ambulance across the United States, we used machine learning models to develop a risk prediction tool for firearm injury using basic demographic information and home ZIP code matched to publicly available data sources.

Methods: We included children and adolescents 0-17 years transported by ambulance to acute care hospitals in 47 states from January 1, 2014 through December 31, 2022. We used 96 predictors, including basic demographic information and neighborhood measures matched to home ZIP code from 5 data sources: EMS records, American Community Survey, Child Opportunity Index, County Health Rankings, and Social Vulnerability Index.

Optimizing the Care of Pediatric Injuries in Rural Environments.

Pediatric readiness is essential to the care of children in rural areas. When pediatric specialty care is not immediately accessible, rural clinicians may be required to care for ill or injured children for extended periods of time. Having established programs for pediatric care, including validated quality and safety programs that emphasize pediatric readiness, is an essential component to caring for rural children.

State and National Estimates of the Cost of Emergency Department Pediatric Readiness and Lives Saved.

Importance: High emergency department (ED) pediatric readiness is associated with improved survival among children receiving emergency care, but state and national costs to reach high ED readiness and the resulting number of lives that may be saved are unknown.

Objective: To estimate the state and national annual costs of raising all EDs to high pediatric readiness and the resulting number of pediatric lives that may be saved each year.

Design, Setting, And Participants: This cohort study used data from EDs in 50 US states and the District of Columbia from 2012 through 2022.

Mesenteric Base Width: Abdominal Wall Diameter Correlates With Intestinal Rotational Anomalies in Infants.

Introduction: Symptomatic malrotation requires urgent Ladd procedure. Patients with incidental or indeterminate findings have historically been managed with observation or operatively. Fluoroscopic identification of the duodenojejunal junction (DJJ) and ileocecal junction (ICJ) can guide operative decision-making, but algorithms have not been validated.

Extreme Weather Injuries and Fatalities, 2006 to 2021.

Importance: Extreme weather has major implications for state and national health care systems; however, statistics examining weather-related injuries and fatalities are limited.

Objective: To examine the frequency and regional distribution of major disaster events (MDEs) in the US.

Design, Setting, And Participants: This ecologic cross-sectional study of MDEs occurring between January 1, 2006, and December 31, 2021, evaluated US data on all injuries and fatalities included in the National Oceanic and Atmospheric Administration National Centers for Environmental Information Storm Events Database.
