Introduction
This study aimed to describe outpatient visit volume in a subspecialty clinic before, during, and after COVID lockdown.
Methods
We assessed monthly in-person and virtual visit volume (telephone-only or video) of 257 patients with rheumatoid arthritis (RA) at one academic center before, during, and post COVID lockdown, November 2018 to September 2021. The primary outcome was monthly visit volume to a rheumatologist. Visit volume, visit type (in-person vs. virtual), and annual visit frequency per patient were assessed. Piecewise Poisson regression models were constructed to examine visit volume trends. Predictors of patient’s visit volume before and after the lockdown were examined using multivariable linear regression.
Results
Median patient age was 58 years; 84% were female; 82% used any disease-modifying anti-rheumatic drug (DMARD), and 62% used a targeted or biologic DMARD. Visit volume was stable 18 months prior to the COVID pandemic [slope 1.00 (95% confidence interval (CI) 0.99–1.01)] and increased at a rate of 2% per month post-lockdown [1.02 (95% CI 1.01–1.03)]. In-person visit volume was greatly reduced during the lockdown, with 61% virtual (51% video, 10% telephone). In the 18 months after lockdown, visit volume rebounded to pre-pandemic levels and continued to increase, with 11% virtual. Older age, serologic status, use of combination DMARDs, and non-steroidal anti-inflammatory drug (NSAID) use predicted greater visit volume during the pre-lockdown period. No variables predicted visit volume post-lockdown.
Conclusion
While COVID caused a huge disruption in rheumatology practice, visit volume for RA rebounded in one American academic center, with an increasing slope in visit volume after lockdown.
