Introduction
Optimal treatment of inflammatory bowel disease requires specialized health care. Patients frequently travel long distances to obtain care for inflammatory bowel disease, which may hinder regular care and affect outcomes adversely.
Methods
This study included patients with established CD or UC receiving care at a single referral center between January 2005 and August 2016. Distance to our healthcare center from the zip code of residence was determined for each patient and classified into quartiles. Our primary outcome was need for IBD-related surgery with secondary outcomes being need for biologic and immunomodulator therapy. Logistic regression models adjusting for relevant covariates examined the independent association between travel distance and patient outcomes.
Results
Our study included 2,136 patients with IBD (1,197 CD, 939 UC) among just over half were women (52%) and the mean age was 41 years. The mean distance from our hospital was 2.5 miles, 8.8 miles, 22.0 miles, and 50.8 miles for the first (most proximal) through fourth (most distant) respectively. We observed a statistically significant and meaningful higher risk among patients in the most distant quartile in the need for immunomodulator use (OR 1.69, 95% CI 1.29–2.22), biological therapy (OR 2.19, 95% CI 1.69–2.85) and surgery (OR 2.44, 95% CI 1.80 – 3.32). Differences remained significant on multivariable analysis and by type of IBD.
Conclusion
Greater distance to referral healthcare center was associated with increased risk for needing IBD-related surgery in patients with Crohn’s disease or ulcerative colitis.
