Physician and Endoscopy Nurse Perspectives on Tap Water for Gastrointestinal Endoscopy: A Cross-Sectional Survey on Support, Perceived Barriers, and Intent to Advocate

BackgroundThe standard water used for endoscopic irrigation is sterile water. Minimal evidence exists regarding sterile water use where there is access to clean water. The WHO has declared the climate crisis as the greatest global health crisis today; we must re-examine our practices and adapt them to promote environmental stewardship while maintaining safety. Method and ObjectiveWe surveyed physicians and endoscopy nurses to determine their attitudes toward tap water use for irrigation in gastrointestinal endoscopic procedures. ResultsThere were 88 complete responses collected from June to November 2024. The majority of respondents and endoscopy-performing consultants expressed comfort with tap water use (59% and 84%, respectively), perceived viability (62% and 68%, respectively), and an interest to implement (73% and 94%, respectively); however, discussions on the topic remained infrequent (77% and 81%, respectively). 82% of overall respondents and 93% of consultants were aware of potential cost-savings, with 69% and 87% more willing to consider tap water based on this. Respondents (60%) and consultants (73%) agree there is a lack of guidelines regarding tap water use and feel that policy barriers will hinder change (59% and 73% respectively). Overall, 59% of respondents and 73% of consultants are likely to advocate for change. ConclusionThe majority of respondents support tap water as a viable, cost-effective alternative with environmental benefits. A strong intention to advocate for change highlights the presence of potential leaders in this space. By promoting and supporting these leaders through education and institutional change, a more sustainable future for endoscopy exists. What is already known on this topicO_LIThere is an urgent need to address the immense impact of medicine on the environment. C_LIO_LIGastrointestinal endoscopy involves the use of large volumes of sterile water to irrigate a non-sterile space in the body. C_LI What this study addsO_LIAllows us to understand the views of physicians on the potential use of tap water in GI endoscopy, as well as understand perceived feasibility and barriers. C_LI How this study might affect research, practice, or policyO_LIWith an understanding of physician support and perceived barriers, specific actions to address these can be taken by regulators. C_LIO_LIBy increasing awareness around the topic, experts can deliberate on the idea and choose to advocate for change, providing leadership in an intimidating discipline. C_LI
