The Cost of Reusable Cystoscopy: A Microcosting Evaluation at a U.S. Academic Medical Center
Hassig et al.
This single-center microcosting evaluation at a U.S. academic hospital reviewed retrospective purchasing and repair data, while following reusable scopes through reprocessing over a two-week period in 2019. The total cost to perform cystoscopy with reusable scopes amounted to $144.73 in 2019 USD. When considering inflation and additional overhead costs in 2024, the total cost amounted to $173.67.
