Infection Prevention:

Microbiology Issues to Consider When Processing Flexible Endoscopes



Multidrug-resistant microorganisms, as well as other pathogenic organisms, have been identified in exposures and transmissions following endoscopy procedures. These organisms can be killed if best practices in flexible endoscope reprocessing are followed. This learner-paced continuing education activity will provide information regarding the impact of incorrect flexible endoscope reprocessing and the subsequent transmission of microorganisms to the next patient.

Target Audience

This faculty-directed education activity is intended primarily for RNs with a responsibility for or an interest in ensuring safe patient care in the endoscopy suite. The presentation will also be of interest to allied healthcare personnel and MDs involved in endoscopy.

Learner Objectives

Upon completion of this presentation, participants will be able to:

  1. Discuss microbiology issues in flexible endoscope reprocessing
  2. Identify strategies for decreasing biofilm on gastrointestinal and other flexible endoscopes.
  3. Review factors impacting infection prevention in flexible endoscope reprocessing.
Teaching Methodology

Participants will complete the recorded webinar learning activity. They will view the presentation, then register to complete the evaluation and take the post-test on the website. They will submit the documentation as directed. A bibliographic reference is included for those wishing additional information.

Contact Hours
