RESUMEN
BACKGROUND AND AIM: Greenhouse gas emissions are the fundamental cause of global warming, with CO2 being the most contributive. Carbon reduction has been widely advocated to mitigate the climate crisis. The endoscopy unit is the third highest waste-generating department in a hospital. The awareness and acceptance of the practice of green endoscopy among healthcare workers is unclear. METHOD: An online survey was conducted over a 5-week period from July to August 2023 in the Asia-Pacific region, which targeted endoscopists, nurses, and other healthcare professionals of the endoscopy unit. The primary outcome was the agreement to adopt green endoscopy. The secondary outcomes included views on sustainable practices, factors associated with increased acceptance of green endoscopy, the acceptance of different carbon reduction measures, and the perceived barriers to implementation. RESULTS: A total of 259 valid responses were received. Overall, 79.5% of participants agreed to incorporate green endoscopy into their practice. Nevertheless, existing green policies were only reported by 12.7% of respondents. The level of understanding of green endoscopy is the only significant factor associated with its acceptance (odds ratio 3.10, P < 0.007). Potential barriers to implementation include healthcare cost increment, infection risk, inadequate awareness, and lack of policy and industrial support. CONCLUSION: Green endoscopy is well accepted among healthcare workers but not widely implemented. The level of understanding is highly associated with its acceptance, highlighting the importance of education. A reliable assessment tool is needed to quantify the environmental impact of endoscopy. Further studies are needed to ascertain its benefit and cost effectiveness.
