Question: 1 / 400

What should be done with endoscopes that show visible soil or bioburden?

They should be disinfected immediately

They should be re-cleaned before disinfection

Endoscopes that display visible soil or bioburden must be thoroughly re-cleaned before they undergo disinfection. This is vital because the presence of any organic matter or contaminants can impede the effectiveness of the disinfection process. Disinfectants work optimally on surfaces that are free of debris; therefore, removing any visible contaminants through re-cleaning ensures that the disinfection agent can adequately penetrate and act on the surfaces of the endoscope.

Successful endoscope reprocessing involves several critical steps: pre-cleaning immediately after use, thorough cleaning to remove all visible contamination, disinfection, and then sterilization when required. This multi-step process is essential in preventing infections and ensuring patient safety. Without re-cleaning, any residual soil could compromise the disinfection process, leading to potential risks in patient care.
