The utility of lighted magnification and borescopes for visual inspection of flexible endoscopes.

INTRODUCTION:Infections have been linked to damaged or contaminated endoscopes with visible defects. Endoscope processing standards and guidelines state endoscopes should be visually inspected every time they are used. This study evaluated a new visual inspection program using magnification and borescopes in an endoscopy department that had not previously utilized these tools. METHODS:Site personnel were given visual inspection tools and training before systematically examining fully processed endoscopes twice during a 2-month period. A risk assessment protocol was used to determine whether endoscopes required recleaning, repair, or other action. Findings were documented using log sheets, photographs, and videotapes. RESULTS:Visible damage and residue or debris were observed in 100% of 25 endoscopes at both assessments, and 76% required repair. Defects at baseline included scratches (88%); channel shredding or peeling (80%); adhesive band disintegration (80%); residual soil or debris (white 84%; black 68%; brown 40%; yellow/green 36%; and orange/red 8%); retained fluid (52%); and dents (40%). Findings were similar at follow-up. DISCUSSION/CONCLUSIONS:Visual inspection with magnification and borescopes identified actionable defects that could interfere with processing effectiveness in 100% of endoscopes. Infection preventionists have a critical role to play in supporting processing personnel now that standards, guidelines, and manufacturer instructions recommend enhanced visual inspection of every endoscope, every time.
