Impact of Borescope Inspections on Endoscope Repair Frequency and Costs

Infections and injuries have been linked to endoscopes with visible damage or residue. Guidelines recommend visual inspection to identify endoscopes requiring repair or further cleaning. This study sought to evaluate the impact of routine borescope inspections on repair frequency and costs. Retrospective analysis was performed on a database of endoscope repairs compiled for a three-year period by a large academic medical center that began performing borescope inspections for every endoscope after manual cleaning. Endpoints included total number of repairs, total repair cost, mean cost per repair, mean turnaround time per repair, and procedural usage between repairs. Subgroup analysis was performed to identify repair patterns by endoscope type. The total cost of repairs decreased from $1,212,702 in 2022 to $724,419 in 2024. The number of repairs required annually was similar over time, but reductions occurred in the proportion of repairs classified as major (12.1% to 3.2%) and the mean cost per repair ($4,426 to $2,337; P < 0.001). Mean turnaround time for repairs decreased (from 24.1 to 15.5 days; P < 0.001). Mean number of uses between repairs increased over time (from 52.1 to 87.2; P < 0.001), and the facility decreased the size of the endoscope fleet from 593 to 508. Significant reductions in endoscope repair frequency and cost occurred over time in a large, centralized endoscope processing department that performed borescope inspections of every endoscope after manual cleaning.
