Drying is a big focus in flexible endoscopy practice right now.  SGNA and other professional societies recommend "complete drying" before storage, but no one prescribes exactly how to get there.  Figuring out the solution is a growing challenge for the typical GI department. Research illustrates that incomplete drying is a source of post-processing contamination and may be related to biofilm proliferation and patient exposure.  Less than optimal storage and transport of high-level disinfected, patient ready endoscopes can also be a source of problems - for your scopes and accessories and for the people on whom they're used. In this faculty-directed, learner-paced activity, you will learn more about what you can do to elevate your practice and safeguard your patients. 

Target Audience

This independent study is intended primarily for RNs with an interest in flexible endoscope reprocessing and ensuring patient safety in GI Endoscopy and other flexible endoscopy procedures. It will also be of interest to allied healthcare personnel and MDs involved in endoscopy.

Learner Objectives

Upon completion of the continuing education activity, participants should be able to:

  • Review evidence-based practice related to the importance of complete drying of flexible endoscopes before use or storage of the endoscopes.
  • Discuss human error observed during endoscope reprocessing research related to drying of the flexible endoscopes after high level disinfection.
  • Compare professional society guideline recommendations for storage of reprocessed flexible endoscopes.
Teaching Methodology
