Climate Sustainability as a Catalyst for Quality and Excellence in Gastrointestinal Endoscopy: A Narrative Review

The significant contribution of greenhouse gas (GHG) emissions to global warming and the resultant negative impact on health is well established. Within the hospital setting, the endoscopy center has been ranked third-after the operating theater complex and intensive care unit-in terms of the volume of hazardous medical waste generated. Such regulated medical waste cannot be recycled, and the disposal process results in higher costs and a larger carbon footprint. There have been clarion calls to reduce the number of endoscopic procedures as a means of reducing GHG emissions. Previous studies have demonstrated the carbon footprint of inappropriate endoscopic procedures. However, endoscopy is an important diagnostic and therapeutic tool that has been shown to be cost-effective. A focus simply on reduction in procedural case volume alone raises the unintended consequences of inequitable access to endoscopy for those in need. A more nuanced approach that is aligned with the innate sense of healthcare professional aspirations and pride, in terms of seeking quality and clinical excellence, should be considered. An evidence-based approach, with a focus on quality and efficiency, as well as appropriate and timely use of new technology, will serve as a catalyst for positive behavioral change toward quality procedures and excellence. This will improve patient satisfaction, increase professional expertise and pride, and reduce carbon footprint through minimization of inappropriate and avoidable repeat procedures.
