Impact of the COVID-19 pandemic on healthcare resource utilization across selected disease areas in the USA.

Aim: To analyze the impact of the COVID-19 pandemic on US healthcare resource utilization. Methods: Optum claims data were used to compare all-cause healthcare visits and healthcare spending for selected diseases between the prepandemic and pandemic periods. Telemedicine use was only assessed for the pandemic period owing to data availability. Results: During the first wave of the pandemic, all-cause healthcare visits across all selected disease areas displayed a rapid decline compared with the prepandemic period, followed by a period of recovery. A reduction in outpatient and home healthcare spending was observed, whereas inpatient and prescription spending increased. Conclusion: Changes in healthcare resource utilization trends were observed during the pandemic. The magnitude of these changes can inform subsequent studies that utilize COVID-19-era data.
