Abstract

Objectives: Many patients transported by Emergency Medical Services (EMS) do not have emergent resource needs. Estimates for the proportion of pediatric EMS calls for low-acuity complaints, and thus potential candidates for alternative dispositions, vary widely and are often based on physician judgment. A more accurate reference standard should include patient assessments, interventions, and dispositions. The objective of this study was to describe the prevalence and characteristics of low-acuity pediatric EMS calls in an urban area.

Methods: This is a prospective observational study of children transported by EMS to a tertiary care pediatric emergency department. Patient acuity was defined using a novel composite measure that included physiologic assessments, resources used, and disposition. Bivariable and multivariable logistic regression were conducted to assess for factors associated with low-acuity status.

Results: A total of 996 patients were enrolled, of whom 32.9% (95% confidence interval, 30.0-36.0) were low acuity. Most of the sample was Black, non-Hispanic with a mean age of 7 years. When compared with adolescents, children younger than 1 year were more likely to be low acuity (adjusted odds ratio, 3.1 [1.9-5.1]). Patients in a motor vehicle crash were also more likely to be low acuity (adjusted odds ratio, 2.4 [1.2-4.6]). All other variables, including race, insurance status, chief complaint, and dispatch time, were not associated with low-acuity status.

Conclusions: One third of pediatric patients transported to the pediatric emergency department by EMS in this urban area are for low-acuity complaints. Further research is needed to determine low-acuity rates in other jurisdictions and whether EMS providers can accurately identify low-acuity patients to develop alternative EMS disposition programs for children.
