Inflammatory Bowel Disease Pharmacist Adherence Counseling Improves Medication Adherence in Crohn's Disease and Ulcerative Colitis.

Background: While inflammatory bowel diseases (IBD) require long-term medication usage to maintain remission, nonadherence is common and adversely associated with poorer clinical outcomes. Personalized IBD Pharmacist Adherence Counselling, based on the Health Beliefs Model of medication perception, may increase medication adherence.

Methods: This prospective multi-center longitudinal parallel study recruited consecutive IBD subjects that were classified as baseline medication non-adherers and adherers.
