    Abstract:
    The objective of this study was to analyze ambulance usage by highest acuity patients as compared with all patients in a suburban pediatric hospital ED. A 1-year retrospective records analysis was conducted of all highest acuity patients (those patients triaged as emergent or critical or admitted to the intensive care unit). A total of 245 patients made 270 high-acuity visits to the ED in 1995. Thirty-one (13%) of the high-acuity patients arrived via ambulance; the rest arrived via private vehicle. The 31 high-acuity patients constituted 8% of the total number of patients arriving by ambulance. There was no significant difference in ambulance usage between insurance groups in the high-acuity patients. Only high-acuity patients with neurologic symptoms (primarily seizures) had a greater relative use of EMS transportation, with 39% of these patients arriving via ambulance (odds ratio 6.6, 95% confidence interval 2.6,16.6). High-acuity patients account for the minority of total ambulance usage in our ED.
