Purpose:
To investigate trends and the potential impact of the COVID-19 pandemic on the utilization of intravitreal antivascular endothelial growth factor (anti-VEGF) pharmaceuticals in an accountable care organization (ACO).
Methods:
We retrospectively analyzed the Centers for Medicare and Medicaid Services beneficiary claims for all patients in the Houston Methodist Coordinated Care ACO registry during the years 2018, 2019, and 2020.
Results:
Across the 3 years studied, a mean of 708 patients received anti-VEGF injections per year. The percentage of patients who received anti-VEGF injections decreased in each sequential year, with a steeper decline during the COVID-19 pandemic in the year 2020 (decrease by 0.4% from 2019 to 2020, P < 0.001; decrease by 0.2% from 2018 to 2019, P = 0.1453). The percentage of patients receiving bevacizumab of the total number of patients receiving any anti-VEGF treatment decreased (bevacizumab decreased by 6% from 2019 to 2020, P = 0.0174; decreased by 7% from 2018 to 2019, P = 0.0074). The COVID-19 pandemic did not seem to correlate with a change in the distribution of the specific anti-VEGF injection used.
Conclusion:
Despite the lower price which may correlate with value-based care, bevacizumab was the least used anti-VEGF treatment. COVID-19 correlated with a larger decrease in the utilization of all three anti-VEGF drugs.
