Preventability of 30-Day Hospital Revisits Following Admission with COVID-19 at an Academic Medical Center

The coronavirus disease 2019 (COVID-19) pandemic may have affected the preventability of 30-day hospital revisits, including readmissions and emergency department (ED) visits without admission. This study was conducted to examine the preventability of 30-day revisits for patients admitted with COVID-19 in order to inform the design of interventions that may decrease preventable revisits in the future.

The study team retrospectively reviewed a cohort of adults admitted to an academic medical center with COVID-19 between March 21 and June 29, 2020, and discharged alive. Patients with a 30-day revisit following hospital discharge were identified. Two-physician review was used to determine revisit preventability, identify factors contributing to preventable revisits, assess potential preventive interventions, and establish the influence of pandemic-related conditions on the revisit.

Seventy-six of 576 COVID-19 hospitalizations resulted in a 30-day revisit (13.2%), including 21 ED visits without admission (3.6%) and 55 readmissions (9.5%). Of these 76 revisits, 20 (26.3%) were potentially preventable. The most frequently identified factors contributing to preventable revisits were related to the choice of postdischarge location and to patient/caregiver understanding of the discharge medication regimen, each occurring in 25.0% of cases. The most frequently cited potentially preventive intervention was "improved self-management plan at discharge," occurring in 65.0% of cases. Five of the 20 preventable revisits (25.0%) had contributing factors that were thought to be directly related to the COVID-19 pandemic.

Although only approximately one quarter of 30-day hospital revisits following admission with COVID-19 were potentially preventable, these results highlight opportunities for improvement to reduce revisits going forward.
