Emergency Medical Services Utilization by Children.

The aim of this study was to compare demographic and clinical features of children (0-14 years old) who arrived at general emergency departments (EDs) by emergency medical services (EMS) to those who arrived by private vehicles and other means in a rural, 3-county region of northern California. We reviewed 507 ED records of children who arrived at EDs by EMS and those who arrived by other means in 2013. We also analyzed prehospital procedures performed on all children transported to an area hospital by EMS. Children arriving by EMS were older (9.0 vs 6.0 years; P < 0.001), more ill (mean Severity Classification Score, 2.9 vs 2.4; P < 0.001), and had longer lengths of stay (3.6 vs 2.1 hours; P < 0.001) compared with children who were transported to the EDs by other means. Children transported by EMS received more subspecialty consultations (18.7% vs 6.9%; P < 0.05) and had more diagnostic testing, including laboratory testing (22.9% vs 10.6%; P < 0.001), radiography (39.7% vs 20.8%; P < 0.001), and computed tomography scans (16.8% vs 2.9%; P < 0.001). Children arriving by EMS were transferred more frequently (8.8% vs 1.6%; P < 0.001) and had higher mean Severity Classification Scores compared with children arriving by other transportation even after adjusting for age and sex (β = 0.48; 95% confidence interval, 0.35-0.61; P < 0.001). Older children received more prehospital procedures compared with younger children, and these were of greater complexity and a wider spectrum. Children transported to rural EDs via EMS are more ill and use more medical resources compared with those who arrive to the ED by other means of transportation.
