Novel Use of Telemedicine by Hurricane Evacuation Shelters

Introduction: Hurricane Florence made landfall in North Carolina as a Category 1 hurricane on September 14, 2018 causing catastrophic flooding throughout much of eastern North Carolina. Large numbers of evacuees were housed in evacuation shelters established by state emergency management and county governments. The purpose of this study was to evaluate the implementation of a telemedicine service in evacuation shelters to determine whether the presence of telemedicine could alter EMS and ED utilization. Methods: We conducted a cross-sectional study that described the EMS and Emergency Department utilization of patients housed in disaster shelters during a 12 day period following Hurricane Florence. Subjects were those shelter residents in Wake or Orange counties utilizing emergency services. Data were collected from Wake County EMS, Orange County EMS, and RelyMD, the telemedicine service utilized in the shelters. Data included subject demographics, chief complaint, case disposition, telemedicine processing times, and an after-call survey to assess satisfaction and emergency department avoidance rates. De-identified data were compiled into Excel spread sheets. Results: There were a total of 194 combined telemedicine and EMS patient encounters, including 63 EMS transports, 25 refusals, 13 referrals (Wake County EMS), and 93 telemedicine patient encounters. Of the telemedicine encounters, 64 evaluations took place in Wake County shelters and 29 evaluations in the Orange County shelter. Average patient age was 49 years old; 67% were female. Forty three patients (46%) utilized the telemedicine service for obtaining medication refills, of whom 19 (44%) indicated they would have otherwise utilized an ED to refill their medication. Forty patients (43%) indicated they would have otherwise gone to an ED for care had the service not been provided, with the needs of 33 (83%) of these patients successfully managed without evaluation in an ED. Only 9 (9.7%) patients were referred by the telemedicine service to an ED for an evaluation, with 3 (3.2%) being admitted. Conclusion: Our descriptive findings suggest telemedicine can be effectively utilized in a general population evacuation shelter to reduce EMS and ED utilization and address the medical needs of the population. Further studies should be performed to assess applicability to other disaster settings.
