School-Based Telemedicine and Reduced Avoidable Emergency Care Among Rural Pediatric Patients

Children living in rural communities have disparate access to preventive health care, shifting the burden of care delivery to emergency services. This study examined the association of school-based telemedicine (SBT) and avoidable emergency department (ED) utilization in rural historically underserved pediatric patients served through an SBT program. A retrospective analysis was conducted using electronic medical records and claims data from a large integrated health care system serving as the majority health care provider in the area. Participants included all pediatric patients served through an SBT program between 2017 and 2020 across three rural North Carolina counties. The study was a quasi-experimental before/after design comparing 12-month time periods before and after a patient's index virtual care visit. A subset of patients served 12 months before the start of the coronavirus 2019 (COVID-19) pandemic in 2020 was extracted and analyzed separately for a sensitivity analysis. The complete sample included 1,236 patients. The odds of having an avoidable ED visit were reduced by 33% between time periods, and the estimated count of visits was reduced by 26%. (Models were adjusted for race/ethnicity, gender, age, and insurance payer.) No significant differences in unavoidable ED utilization were observed. The sensitivity analysis showed similar trends. Results demonstrate that telemedicine can improve access to health care and may offset the burden of avoidable care through emergency health services. Policy changes and increased use during the COVID-19 pandemic have created an optimal environment for telemedicine expansion to reduce health care access disparities.
