What is a necessary step in the reprocessing of flexible endoscopes after high-level disinfection?

Flushing alcohol through the accessory channels is a necessary step in the reprocessing of flexible endoscopes after high-level disinfection because it helps to ensure that all residual moisture, bioburden, and disinfectant are effectively removed from the channels. The use of alcohol, which evaporates quickly, assists in drying the channels and preventing the growth of microorganisms, which could occur if moisture is left within them. This step is critical for maintaining the integrity of the endoscope and ensuring that it is safe for patient use in subsequent procedures.

In contrast, while final inspection of the endoscope is also important for confirming the equipment's condition and ensuring that it is fully cleaned and functional, it does not directly contribute to the immediate step following high-level disinfection. Immediate storage in a cabinet does not address the critical need for thorough drying and remaining bioburden removal, and the application of a protective coating, while it may have benefits for other aspects of endoscope maintenance, is not a primary step in the reprocessing workflow after disinfection.
