Objective: To summarize existing literature examining interventions to enhance medication adherence and their effectiveness in enhancing care for inflammatory bowel disease (IBD) patients.

Methods: This review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. PubMed and Embase were searched for studies from June 2014 to Dec 2020. Only the studies published in English were included.

Results: Our systematic literature search identified 488 published articles. Seventeen studies with a total of 7073 patients were included. Out of seventeen different interventions, five were classified as educational, eight as multicomponent, three as behavioral and one as cognitive behavioral. Adherence was measured using patient self-report, administrative/pharmacy claims data, and electronic monitoring devices/pill dispensing systems. Twelve out of seventeen interventions showed a statistically significant improvement in medication adherence including three educational, seven multicomponent, one behavioral and one cognitive behavioral intervention.

Conclusions: Multicomponent interventions demonstrated the greatest success in IBD patients in promoting medication adherence. Future research should focus on a multidisciplinary approach to design multicomponent interventions to optimize treatment adherence and enhance long-term clinical outcomes.

Practice implications: While stand-alone strategies have demonstrated effectiveness in improving adherence, better outcomes may be achieved by combining multiple strategies.
