Characteristics and Treatment Outcomes of Transition among Patients with Inflammatory Bowel Disease.

Abstract

This study aimed to assess disease characteristics and outcomes of transition in patient care among adolescent patients with inflammatory bowel disease (IBD). Data from patients younger than 18 years who were diagnosed with IBD (Crohn's disease, ulcerative colitis, or intestinal Behçet's disease) were investigated. We categorized the patients into two groups: transition IBD group (Group A, diagnosed in pediatric care followed by transfer to/attendance in adult IBD care) and non-transition group (Group B, diagnosed and followed up in pediatric care or adult IBD care without transfer). Data from a total of 242 patients [Group A (n=29, 12.0%), Group B (n=213, 88.0%)] were analyzed. A significantly higher number of patients was diagnosed at an earlier age in Group A than in Group B (p<0.001). Group A patients had more severe disease in terms of number of disease flare ups (p=0.011) and frequency of bowel-related complications (p<0.001). Multiple linear regression analysis showed that Group B patients had more medical non-compliance than Group A patients (β=2.31, p=0.018). After transition, IBD-related admission frequency, emergency admission frequency, disease flare frequency, and medical non-compliance were significantly improved. The transition IBD group had more severe disease. Medical non-compliance was lower in the transition IBD group. Clinical outcomes improved after transition.
