Prospective Evaluation of the Carbon Footprint and Clinical Utility of IBUS Compared to Colonoscopy and Enterography in UC and CD

NCT07431983 | Recruiting

• 1 other identifier: IBUS1
• Study Type: observational
• Target: 200
• Locations: 1 country
• Sites: 2

Brief Summary

Healthcare contributes approximately 4.4% of global GHG emissions, with diagnostic imaging and endoscopic services being substantial contributors. Colonoscopy and cross-sectional imaging modalities, though indispensable, are associated with high carbon emissions due to electricity use, waste, sterilisation, and transportation. IBUS, a non-invasive, real-time diagnostic modality, is increasingly validated for disease activity assessment in both UC and CD.

Conditions

Ulcerative Colitis (UC); Crohns Disease

Outcome Measures

Primary Outcomes (1)

• The electricity consumed, water consumed, waste generated, and Greenhouse Gas (GHG) emissions will be analyzed

  The waste generated will be stratified according to the methods of disposal as Direct landfill, Incineration, and landfill or Recyclable waste. The electricity consumed, water consumed, waste generated, and Greenhouse Gas (GHG) emissions will be analyzed. The unit of emissions will remain same kgCO2e and the total emissions will then be calculated.

  12 months

Study Arms (2)

Ulcerative colitis

carbon footprint and clinical usefulness of Intestinal Bowel Ultrasound (IBUS) with standard imaging colonoscopy in patients with Ulcerative Colitis Colonoscopy+ IBUS

Crohns disease
