Accurate estimates for the risk of COVID‐19 in IBD, and an understanding of the impact of COVID‐19 on IBD course and the risk of incident post‐infectious IBD are needed.

To estimate the risk of COVID‐19 in IBD and study its impact on IBD course and the risk of incident post‐infectious IBD.

A retrospective propensity score matched cohort study utilising multi‐institutional research network TriNetX. COVID‐19 patients with and without IBD were identified to quantify the risk of COVID‐19 in patients with IBD, COVID‐19 outcomes in patients with IBD and the impact of COVID‐19 on IBD disease course. The risk of incident post‐infectious IBD in COVID‐19 patients was compared to the population not infected with COVID‐19 during a similar time period.

Incidence rate ratio for COVID‐19 was lower in IBD patients compared to the non‐IBD population (0.79, 95% CI: 0.72‐0.86 …
