Emergency Care for Children in the United States: Epidemiology and Trends Over Time

Abstract

Background: The emergency care system for children in the United States is fragmented. A description of epidemiological trends based on emergency department (ED) volume over time could help focus efforts to improve emergency care for children.

Objectives: To describe the trends of emergency care for children in the United States from 2006-2014 in EDs across different pediatric volumes.

Methods: We analyzed pediatric visits to EDs using the Health Care Utilization Project Nationwide Emergency Department Sample in a representative sample of 1,000 EDs annually from 2006-2014. We report trends in disease severity, mortality, and transfers based on strata by pediatric volume and other hospital characteristics.

Results: From 2006-2014, there were 318,114,990 pediatric ED visits. Pediatric visits remained steady but declined as a percentage of total visits (-3.91%, p = 0.0007). The majority (92.7%) of children were cared for in lower-volume EDs (<50,000 pediatric visits/year), where mortality was higher vs. the highest-volume EDs. Mortality decreased over time (0.34/1,000 to 0.27, p = 0.0099), whereas interhospital transfers increased (p = 0.0020). ED visits increased for children with Medicaid insurance (40.7% to 56.7%, p < 0.0001), whereas rates of self-pay insurance decreased (13.6% to 9.45%, p = 0.0006). The most common reasons for pediatric ED visits were trauma (25.6%); ear, nose, and throat; dental/mouth disorders (21.8%); gastrointestinal diseases (17.0%); and respiratory diseases (15.6%).

Conclusions: Overall, pediatric ED visits have remained stable, with lower mortality rates, whereas Medicaid-funded pediatric visits have increased over time. Most children still seek care in lower-volume EDs. Efforts to improve pediatric care could be best focused on lower-volume EDs and interhospital transfers.
