Effect of the COVID-19 pandemic on elective cataract surgery wait times.

OBJECTIVE

Lengthy wait times for cataract surgery can negatively affect patients' quality of life and increase the incidence of falls and depression. The COVID-19 pandemic has presented significant challenges to the delivery of elective cataract surgeries. The effects of the COVID-19 pandemic on cataract surgery wait times in the Alberta Health Services' Edmonton zone were studied by examining the wait times before and during the pandemic.

METHODS

This study was conducted based on a retrospective population-based design. Data were compiled from a centralized database related to hospital-based cataract surgery (Royal Alexandra, Fort Saskatchewan, and WestView Health Centre) between April 2019 and March 2022 (i.e., 3 fiscal years).

RESULTS

The average wait time for cataract surgery increased from 14.4 ± 1.4 weeks in 2019-2020 to 18.2 ± 2.7 weeks in 2020-2021 (p = 0.005) and then decreased to 11.5 ± 1.3 in 2021-2022 (p < 0.001). The number of completed surgeries decreased from 13,103 in 2019-200 to 9,308 (p = 0.09) and 10,365 (p = 0.1) during the next 2 years. The annual operating room time for scheduled cases was reduced to 4463 hours (p = 0.42) and 4552 hours (p = 0.15) during the pandemic compared with 5541 hours before the pandemic. However, the average waitlist size decreased from 6629 at the end of 2019-200 to 6122 (p = 0.029) and 4011 (p < 0.001) during the next 2 years.

CONCLUSION

The COVID-19 pandemic resulted in significantly increased average wait times for elective cataract surgery during the first year of the pandemic. Because of a reduction of the waitlist size, the wait times decreased during the second year of the pandemic.
