  • Examining Differences in Rural and Urban Medicare FFS Beneficiaries' Emergency Department Use Pre-COVID-19 and During COVID-19
    This study described and compared the differences in the utilization of emergency department (ED) services among rural and urban Medicare Fee-For-Service enrollees during 2018-2021. Researchers identified factors associated with differences in ED use, including shifts in volume, primary diagnoses, and admission source, before and since the COVID-19 public health emergency in rural and urban areas.
