PDTree: An EMS Triage Tool for Pediatric Destination Decision Making

Sept. 1, 2016 - Aug. 31, 2020

Grant Number
Project Overview
Pediatric specific prehospital triage tools are long overdue. Regionalized care demands that patient classification begins in the prehospital arena. This project aims to produce a viable tool that supplements prehospital provider judgment and improves accuracy of pediatric transport destination choices. Goals: (1) Develop the Pediatric Decision Tree (PDTree), a triage tool to guide EMS transport destination choice for ill and injured patients; (2) Measure impact of the PDTree in pilot test use by EMS agencies; (3) Disseminate the PDTree and enable adaptation and adoption by EMS agencies throughout the US.
