Impact of the Coronavirus Disease 2019 Pandemic on Surgical Volumes Among Fellowship-Trained Glaucoma Subspecialists.

PRCIS

The change in glaucoma surgical volumes due to the coronavirus disease 2019 pandemic was not uniform across procedure types and was unequal between rural and urban practice locations.

PURPOSE

To quantify the impact of the coronavirus disease 2019 pandemic on surgical volumes performed by fellowship-trained glaucoma subspecialists.

MATERIALS AND METHODS

This retrospective cohort analysis of the Centers for Medicare and Medicaid Services Medicare Public Use File extracted all glaucoma surgeries, including microinvasive glaucoma surgeries (MIGSs), trabeculectomy, goniotomy, lasers, and cataract surgery, performed by fellowship-trained glaucoma surgeons in rural and urban areas between 2016 and 2020. Predicted estimates of 2020 surgical volumes were created utilizing linear squares regression. Percentage change between predicted and observed 2020 surgical volume estimates was analyzed. Statistical significance was achieved at P 0.05). The number of goniotomies decreased by 10% more in rural areas than in urban areas (-22% and -12%, respectively). Laser procedures decreased by 8% more in urban areas than in rural areas (-18% and -10%, respectively).

CONCLUSIONS

Among glaucoma-trained surgeons, glaucoma surgeries experienced a greater volume loss than cataract surgeries. In urban US areas, relative reductions in MIGS and goniotomy volumes in urban areas may have been compensated by greater laser and trabeculectomy volumes. Trabeculectomies in rural areas were the only group exceeding predicted estimates. Glaucoma subspecialists may utilize these findings when planning for future events and in overcoming any remaining unmet need in terms of glaucoma care.
