23 Triage and Transfer to a Regional Burn Center - Impact of a Mobile Phone App

Abstract

Abstract Introduction The ABA designs referral criteria to guide providers in recommending appropriate patients for treatment at specialized burn centers. However, patients are typically triaged at local facilities where providers may not have expertise to assess burn injuries properly. Addition of a visual component to a consultation call can improve local triage decisions, including estimations of total burn surface area (TBSA). In 2016, our regional burn center implemented a mobile phone app, which allows a referring provider to send photos of the wound along with basic demographic data to the burn specialist in a HIPPA-compliant manner, facilitating the consultation. Our hypothesis is that use of the burn app can improve triage decisions, particularly in cases of intermediate TBSA (1–10%). Methods This is a retrospective review of all consults to our ABA-verified burn center from a single Level II trauma center (TC) approximately 70 miles from our institution. Data were integrated from our call center, burn registry, electronic medical record and the mobile app. Burns were classified as large (>10% TBSA), intermediate (1–10% TBSA), or small (< 1%). Patients were triaged to either a) immediate transfer via ground ambulance or helicopter, b) transfer via private vehicle, c) outpatient follow up at the burn center, or d) local facility/primary care management. Patients were considered to be “down-triaged” if they required transfer but could transfer via private vehicle, or if they could be managed locally. Results During the study period, 135 patient consultations were made by the TC for thermal or cold injuries. 82 patients (61%) were referred using the app. Most patients (n=56, 41%) presented with small burns of the hands, feet or face. Overall, 53 patients (39%) were transferred to the burn center. The majority required ambulance transfer (n=44). 60 patients (44%) were recommended for outpatient follow up, but only 43% (n=26) followed up. When the subset of intermediate burns was considered (n=54), the mobile app allowed for successful “down-triage” of 12 patients (30%) referred through the app. No patient referred without the app could be “down-triaged” (p=0.02). Conclusions A mobile app can be used to successfully triage patients with intermediate size burn injuries to a lower acuity of follow up and transfer mode. However, less than half of patients triaged to outpatient follow up were actually seen at the burn center. Applicability of Research to Practice Telemedicine can be used to assist in triage decisions and appropriate referral to a regional burn center. This technology could be optimized to assist in outpatient follow up.
