Secondary Overtriage in a Pediatric Level One Trauma Center

Abstract Background Previous studies have explored under- and overtriage, and the means by which to optimize these rates. Few have examined secondary overtriage (SO), or the unnecessary transfer of minimally injured patients to higher level trauma centers. We sought to determine the incidence and impact of SO in our pediatric level one trauma center. Methods We performed a retrospective analysis of all trauma activations at our institution from 2015 through 2017. SO was defined as transferred patients who required neither PICU admission nor an operation, with ISS ≤ 9 and LOS ≤ 24 hours. We compared SO patients against all trauma activation transfers, and against similar non-transferred patients. Results We identified 1,789 trauma activations, including 766 (42.8%) transfers. Of the transfers, 335 (43.7%) met criteria for SO. Compared to other transfers, SO patients had a shorter mean travel distance (52.9 v 58.1 mi; p = 0.02). Compared to similar patients transported from the trauma scene, SO patients were more likely to be admitted (52.2% v 29.2%; p Conclusions SO represents an underrecognized burden to trauma centers which could be minimized to improve resource allocation. Future research should evaluate trauma activation criteria for transferred pediatric patients.
