M Desai et al. Gastroenterol 2024; 166: 496-502. The Environmental Impact of Gastrointestinal Procedures: A Prospective Study of Waste Generation, Energy Consumption, and Auditing in an Endoscopy Unit
This study prospectively collected data on total waste generation, energy consumption, and the role of intraprocedural inventory audit of a single tertiary care academic endoscopy unit over a 2-month period (May–June 2022, 450 procedures).
Key findings:
- The total waste generated during the study period was 1398.6 kg (61.6% directly going to landfill, 33.3% biohazard waste, and 5.1% sharps), averaging 3.03 kg/procedure.
- The average waste directly going to landfill was 219 kg per 100 procedures. The estimated total annual waste generation approximated the size of 2 football fields (1-foot-high layered waste).
- Endoscope reprocessing generated 194 gallons of liquid waste per day, averaging 13.85 gallons per procedure.
- Thus, every 100 GI endoscopy procedures (esophagogastroduodenoscopy/colonoscopy) was associated with 303 kg of solid waste and 1385 gallons of liquid waste generation
- 20% of total waste consisted of potentially recyclable items (8.6 kg/d) that could be avoided by appropriate waste segregation of these items.
My take: The huge amount of trash (solid and liquid) generated by endoscopy is difficult to fathom. It is incumbent for gastroenterologists to consider this hidden extra cost. Recycling could help in a modest way. Trying to limit low-value procedures is another step. Long-term alternative diagnostic procedures will need to be developed/utilized which reduce the environmental impact.
