Pediatric and Adult Fracture Incidence: A Decreasing Trend With Increasing Hospital Admissions

Abstract

Large-scale studies examining fracture trends and epidemiological data are lacking. The purpose of this study was to evaluate the incidence of fractures presenting to US emergency departments using the National Electronic Injury Surveillance System. A total of 7,109,078 pediatric and 13,592,548 adult patients presenting to US emergency departments with a fracture between 2008 and 2017 were analyzed for patterns. Fractures accounted for 13.9% of pediatric injuries and 15% of adult injuries. Among children, fracture incidence was highest in the group 10 to 14 years old and most frequently involved the forearm (19.0%). Fracture incidence was highest in adults 80 years and older and most frequently involved the lower trunk (16.2%). On average, the rate of pediatric fractures decreased by 2.34% per year (95% CI, 0.25% increase to 4.88% decrease; P =.0757). Among adults, fracture incidence increased 0.33% per year (95% CI, 2.34% decrease to 2.85% increase; P =.7892). This change was significantly different between the pediatric and adult populations ( P =.0152). There was an increase in the annual proportion of adults with fractures who were admitted (odds ratio per 1-year increase, 1.05; 95% CI, 1.03–1.07; P <.0001). There was no change in the proportion of pediatric patients with fractures who were admitted (odds ratio, 1.02; 95% CI, 0.99–1.05; P =.0606). The incidence of fractures decreased in pediatric patients yet was relatively stable in adult patients. Conversely, the proportion of patients with fractures who were admitted increased, particularly among adults. These findings may suggest that less severe fractures are presenting elsewhere, falsely inflating the observed rise in admissions. [ Orthopedics . 202x;4x(x);xx–xx.]
