Patient-Reported Pain Distributions in Inflammatory Bowel Disease: Impact on Patient Psychosocial Outcomes

Abstract

Inflammatory bowel disease (IBD) is a painful chronic gastrointestinal disease associated with diminished quality of life. No research documents IBD body pain or the associations of pain patterns to outcomes. Objectives were to map patient body pain areas and examine the associations between pain patterns with depression, catastrophizing, pain severity, and quality of life. A cross-sectional survey was collected from consecutive tertiary-care IBD clinic patients (n = 255). Patients were classified into three pain pattern groups (No Pain; Localized Pain Only; and Widespread Pain) with more than 40% reporting widespread pain. The Localized Pain Only and Widespread Pain groups reported pain in the abdomen, the uterus/testes, vagina/penis, bladder, and pelvis/buttock areas. The body area most often reported was the anterior abdomen for the Localized Pain Only and Widespread Pain groups, with additional endorsement of lower back and anterior thigh and knees for the Widespread Pain group. The pain versus no pain patients reported greater depressive symptoms, catastrophizing, and diminished quality of life. Patients reported a variety of pain patterns during clinic visits. Widespread pain is associated with greatest pain and poorest psychosocial outcomes.
