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.
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.
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.
感染与有可见缺陷的受损或受污染内窥镜有关。内窥镜处理标准和指南规定,每次使用内窥镜时都应进行目视检查。本研究评估了一种在内镜检查科室使用放大装置和管道镜的新目视检查程序,该科室此前未使用过这些工具。
在2个月的时间内,现场工作人员在系统地对完全处理后的内窥镜进行两次检查之前,获得了目视检查工具并接受了培训。使用风险评估方案来确定内窥镜是否需要重新清洗、维修或采取其他措施。使用记录表、照片和录像记录检查结果。
在两次评估中,25台内窥镜中有100%观察到可见损伤、残留物或碎片,76%需要维修。基线时的缺陷包括划痕(88%);通道撕裂或剥落(80%);胶带分解(80%);残留污垢或碎片(白色84%;黑色68%;棕色40%;黄绿36%;橙红色8%);残留液体(52%);以及凹痕(40%)。随访时的结果相似。
讨论/结论:使用放大装置和管道镜进行目视检查发现了可导致行动的缺陷,这些缺陷可能会干扰100%的内窥镜的处理效果。鉴于标准、指南和制造商说明建议每次对每台内窥镜进行强化目视检查,感染预防人员在支持处理人员方面可发挥关键作用。
