Background: The objectives of this survey study were to assess duodenoscope precleaning and manual cleaning times, identify human factors issues in duodenoscope reprocessing workflow or ergonomics, and ascertain any best practices in duodenoscope reprocessing. Methods: Researchers developed the confidential, qualitative, online Duodenoscope Reprocessing Workflow and Ergonomic Design Human Factors Survey with an intended audience of healthcare workers (HCWs) who routinely perform duodenoscope precleaning or manual cleaning. The unrestricted survey link was distributed to target HCW email addresses in December 2020; the survey closed in January 2021. Results: Three hundred and forty-one individuals completed the survey. Most respondents complete duodenoscope precleaning in 10 minutes or less and manual cleaning in 16-to-30 minutes. Most respondents’ facilities use fixed distal endcap duodenoscopes. Most respondents experience pressure to work faster when cleaning duodenoscopes and reported that cleaning duodenoscopes caused fatigue or discomfort in at least one body part. Mentoring HCWs and retaining experienced staff were 2 primary duodenoscope reprocessing best practices identified by respondents. Discussion and Conclusions: To enhance duodenoscope cleaning, facilities should provide ample reprocessing work spaces with incorporated height-adjustable work surfaces, train HCWs on validated duodenoscope reprocessing instructions, provide step-by-step instructions for HCWs when duodenoscope cleaning is performed, mentor reprocessing HCWs, and retain experienced staff.
