At-Home Urea Breath Testing Demonstrates Increased Patient Uptake, High Satisfaction Rates, and Reduction in Carbon Emission Due to Eliminated Hospital Attendances, While Maintaining Diagnostic Accuracy for H. pylori

<b>Background/Objectives</b>: Healthcare accounts for approximately 4.4% of global carbon emissions. Gastroenterology is a particularly heavy producer, with professional organisations outlining targets to move towards carbon neutrality. Missed hospital appointments, associated with poor medical outcomes, also represent physical and economic waste to the sector. COVID-19 expedited the shift toward virtual clinics, but tele-diagnostics have not expanded similarly. We aimed to assess the feasibility of a virtual C13 urea breath test clinic for <i>H. pylori</i> in Ireland. <b>Methods</b>: C13 urea breath test kits were provided to patients in the community, who were subsequently invited to book an online video appointment with a GI lab technician to assist them in performing the test at home. Completed tests were returned to the hospital via local GP, by post, or a specified hospital drop-off point, and analysed using our standard protocol. <b>Results</b>: 423 virtual appointments were reviewed. 135 (32%) were male, and the mean age was 42 years. The test positivity rate was 22%, similar to a matched in-person testing cohort (21%). In all, there were no non-attenders, and two cancellations. Virtual patients were more likely to attend their appointments (OR = 153.9, <i>p</i> = 0.0004) than in-person patients. Virtual UBT appointments saved 9943.5 Km of road journeys, equivalent to 254 person-hours of travel time and 1.24 metric tonnes of CO₂. Additionally, 300 (71%) patients returned a feedback questionnaire, of which 276 (92%) rated the overall home breath test experience as 'good' or 'excellent'. <b>Conclusions</b>: Home testing for <i>H. pylori</i> is effective, acceptable, and reduces both reliance on invasive procedures such as endoscopy and carbon emissions.
