Implementation evaluation of tiered tele-triage pathways for burn center consultations and transfers

Early transfer to specialized centers improves trauma and burn outcomes; however, overtriage can result in unnecessary burdens to patients, providers, and health systems. Our institution developed novel burn triage pathways in 2016 to improve resource allocation. We evaluated the implementation of these pathways, analyzing trends in adoption, resource optimization, and pathway reliability after implementation.

Triage pathways consist of transfer nurses (RNs) triaging calls based on review of burn images and clinical history: green pathway for direct outpatient referral, blue pathway for discussion with the on-call provider, red pathway for confirmation of transfer as requested by referring provider, and black pathway for the rapid transfer of severe burns. We used the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework to evaluate implementation. These pathways affected all acute burn referrals to our center from January 2017 to December 2019 (reach). Outcomes of interest were pathway assignment over time (adoption), changes to burn provider call volume (effectiveness), and the concordance of pathway assignment with final disposition (implementation reliability).

Transfer RNs triaged 5,272 burn referrals between 2017 and 2019. By January 2018, >98% of referrals were assigned a pathway. In 2018-2019, green pathway calls triaged by RNs reduced calls to burn providers by a mean of 40 (SD, 11) per month. Patients in green/blue pathways were less likely to be transferred, with >85% receiving only outpatient follow-up ( p < 0.001). Use of the lower acuity pathways increased over time, with a concordant decrease in use of the higher acuity pathways. Younger adults, patients referred from Level III to Level V trauma centers and nontrauma hospitals, and patients referred by APPs were less likely to be triaged to higher acuity pathways.

Implementation of highly adopted, reliable triage pathways can optimize existing clinical resources by task-shifting triage of lower acuity burns to nursing teams.
