ACCURACY OF EMS TRAUMA TRANSPORT DESTINATION PLANS IN NORTH CAROLINA

Objective. Planning for time-sensitive injury may allow emergency medical services (EMS) systems to more accurately triage patients meeting accepted criteria to facilities most capable of providing life-saving treatment. In 2010, North Carolina (NC) implemented statewide Trauma Triage and Destination Plans (TTDPs) in all 100 of North Carolina's county-defined EMS systems. Each system was responsible for identifying the specific destination hospitals with appropriate resources to treat trauma patients. We sought to characterize the accuracy of their hospital designations. Methods. In this cross-sectional study, we collected TTDPs for each county-defined EMS system, including their assigned hospital capabilities (i.e., trauma center or community hospital). We conducted a survey with each EMS system to determine how their TTDP was constructed and maintained, as well as with each TTDP-designated hospital to verify their capabilities. We determined the accuracy of the EMS assigned hospital designations by comparing them to the hospital's reported capabilities. Results. The 100 NC EMS systems provided 380 designations for 112 hospitals. TTDPs were created by EMS administrators and medical directors, with only 55% of EMS systems engaging a hospital representative in the plan creation. Compared to the actual hospital capabilities, 97% of the EMS TTDP designations were correct. Twelve hospital designations were incorrect and the majority (10) overestimated hospital capabilities. Of the 100 EMS systems, 7 misclassified hospitals in their TTDP. EMS systems that did not verify their local hospitals' capabilities during TTDP development were more likely to incorrectly categorize a hospital's capabilities (p = 0.001). Conclusions. A small number of EMS systems misclassified hospitals in their TTDP, but most plans accurately reflected hospital capabilities. Misclassification occurred more often in systems that did not consult local hospitals prior to developing their TTDP. The potential of the TTDP to improve communication between EMS agencies and the facilities with which they work has not been fully realized. EMS agencies or systems should verify local hospital capabilities when engaging in destination planning efforts.
