Motivations behind complementary and alternative medicine use in patients with Crohn’s disease and ulcerative colitis

Abstract

Abstract Background Complementary and alternative medicine (CAM) use is common in inflammatory bowel disease (IBD) patients and impacts compliance with conventional treatment. Gastroenterologists should understand the motivational factors of CAM use—factors that push patients away from standard therapy or pull towards CAM. Our study describes the motivations behind CAM use for IBD and evaluates differences between Crohn’s disease (CD) and ulcerative colitis (UC) patients. Methods Retrospective cohort survey of patients over 18 years old with IBD, evaluated by gastroenterologists at a tertiary care referral centre from January 1 to December 31, 2019. Only patients who reported CAM use were included. Chi-square and independent t-tests were performed and P-value <0.05 was significant. Results Of the 230 completed surveys, 193 reported CAM use (CD: 57.5% vs UC: 42.5%). Demographics, disease duration, and hospitalizations were similar, but CD patients had lower SIBDQ scores (CD: 48.1 vs UC: 53.5, P < 0.001). Both groups were largely influenced by their social network to use CAM (CD: 33% vs UC: 31.3%) and did not feel well informed about CAM (87.4%). CD and UC patients had similar push and pull factors. Push factors included lack of improvement (39%) and side effects (20%) with conventional treatment. Pull factors included the desire for a holistic approach (21%) and to improve mood (35%). UC patients wanted a natural approach to treat their IBD, which nearly reached significance (P = 0.049). Most patients hoped fatigue 62.7%, and diarrhoea 61.7% would improve with CAM, but more CD patients wanted to improve their appetite (P = 0.043). Conclusion Despite differences in QoL, push and pull motivations for CAM use did not differ between CD and UC patients. Most users do not feel well informed of CAM and ongoing dialogue is important for patient-centred care.
