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.
Dr Darren Tiao and colleagues performed a prospective multi-center longitudinal parallel study that recruited consecutive IBD subjects that were classified as baseline medication non-adherers and adherers.
Non-adherers received a single IBD Pharmacist Adherence Counselling intervention at baseline, while adherers served as controls.
The team administered Medication Adherence Report Scale and Beliefs about Medicines Questionnaire up to 24 months.
|Nonadherence in the IBD Pharmacist Adherence Counselling group decreased from 100% to 44%|

Medication acceptance was defined as high perception of medication necessity with low concerns.
The researchers' primary endpoint was medication adherence at 24 months.
Of 114 subjects approached, 100 completed follow-up, with 36 being baseline nonadherers, and 64 baseline adherers.
At 24 months, nonadherence in the IBD Pharmacist Adherence Counselling group decreased from 100% to 44%, whereas nonadherence in controls remained unchanged.
Individually, the team noted that Beliefs about Medicines Questionnaire Necessity and Concern scores showed no significant changes in both groups, but medication acceptance significantly improved in baseline nonadherers at 12 months with a trend toward durable improvement at 24 months.
Dr Tiao's team concludes, "Medication nonadherence in IBD can be improved through a single personalized counseling session by an IBD pharmacist, and the benefit was durable for 2 years."
"This benefit was through improving the acceptance of medication."
