# Poster Session II - A291 THE ENVIRONMENTAL IMPACT OF VIRTUAL SPECIALIST CARE AMONG INDIVIDUALS WITH INFLAMMATORY BOWEL DISEASE IN ONTARIO

## TL;DR

Virtual specialist care for inflammatory bowel disease in Ontario significantly reduced transportation-related carbon emissions during the pandemic.

## Contribution

Quantifies the environmental benefits of virtual IBD specialist care in Ontario during the early pandemic period.

## Key findings

- Virtual IBD specialist visits in Ontario avoided 6.7 million kilometers of travel.
- This resulted in a reduction of approximately 1.38 million kilograms of CO2 emissions.

## Abstract

Transportation to and from healthcare appointments contributes substantially to healthcare-related greenhouse gas emissions. During the COVID-19 pandemic, widespread adoption of virtual care transformed healthcare delivery. However, the environmental benefits of this transition remain poorly quantified in the Canadian context, particularly for chronic conditions such as inflammatory bowel disease (IBD) that require ongoing specialist follow-up.

Our aim was to estimate the travel distance and associated reduction in transportation-related carbon emissions attributable to virtual IBD specialist visits in Ontario during the first year of the COVID-19 pandemic.

We used administrative databases at ICES, Ontario. Individuals in the Ontario Crohn’s and Colitis Cohort between April 1, 2020 and March 31, 2021 were included. Specialist visits were classified as in-person or virtual using Ontario Health Insurance Plan fee codes. Each patient’s residential postal code was linked to their IBD specialist’s office location through the ICES Physician Database. The round-trip distance between the patient’s residence and the clinic was calculated for every virtual visit to represent kilometers of travel avoided. Total avoided distance was converted into carbon dioxide (CO2) emissions using an emission factor of 206 g CO2 per kilometer, reflecting average passenger-vehicle emissions in Canada.

A total of 98,099 adults with IBD in Ontario were identified. The cohort was 48% male and 52% female, and 11% lived in rural regions of Ontario. Ninety-two percent of all IBD specialist visits were virtual during the study period. The number of kilometers of travel avoided, and reductions in carbon emissions are shown in Table 1. The cumulative travel distance avoided through virtual visits was estimated at 6.7 million kilometers, corresponding to approximately 1.38 million kilograms of CO2 emissions prevented.

The rapid uptake of virtual IBD specialist care during the COVID-19 pandemic led to a measurable reduction in transportation-related carbon emissions across Ontario. These findings highlight the potential for virtual healthcare to advance environmental sustainability goals while maintaining continuity of care for patients with chronic disease. As healthcare systems consider post-pandemic models of care, integrating environmental metrics into virtual care policy planning may support Canada’s broader climate action objectives.
