Review article: medication non-adherence in ulcerative colitis--strategies to improve adherence with mesalazine and other maintenance therapies

Abstract

Background: Significant number of patients with ulcerative colitis (UC) fail to comply with treatment.

Aims: To review issues surrounding medication non-adherence in inflammatory bowel disease (IBD), including the clinical and health service implications in the UK, and discuss strategies for optimizing medication adherence.

Methods: Articles cited were identified via a PubMed search, utilizing the words IBD, adherence, compliance, medication and UC.

Results: Medication non-adherence is multifactorial involving factors other than dosing frequency. Male gender (OR: 2.06), new patient status (OR: 2.14), work and travel pressures (OR: 4.9) and shorter disease duration (OR: 2.1), among others are proven predictors of non-adherence in UC. These indicators can identify 'at-risk' patients and allow an individually tailored treatment approach to be introduced that optimizes medication adherence. A collaborative relationship between physician and patient is important; several strategies for improving adherence have been proven effective including open dialogue that takes into consideration the patient's health beliefs and concerns, providing educational (e.g. verbal/written information, self-management programmes) and behavioural interventions (e.g. calendar blister packs, cues/reminders).

Conclusions: Educational and behavioural interventions tailored to individual patients can optimize medication adherence. Additional studies combining educational and behavioural interventions may provide further strategies for improving medication adherence rates in UC.
