Impact of a pre-visit glaucoma video/question prompt list intervention on Black patient eye drop adherence during a 12-month period: A randomized controlled trial.

SIGNIFICANCE: Black patients with glaucoma who received the pre-visit question prompt list/video intervention and asked one or more questions during visits were significantly more likely to take the percentage of correct prescribed doses each day and the percentage of correct number of doses each day on schedule over a 12-month period. PURPOSE: The study aimed to examine the impact of a randomized, controlled trial to test the effectiveness of a pre-visit glaucoma video/question prompt list intervention on Black patient glaucoma medicine adherence over a 12-month period. METHODS: One hundred eighty-nine Black patients with glaucoma were enrolled and randomized to either a usual care or pre-visit video/question prompt list intervention. Patients who reported being nonadherent on one of two measures were enrolled into the trial. Baseline and 6-month visits were audio-taped, and patients were interviewed afterwards. This manuscript focuses on the longitudinal 12-month adherence data, which has not been reported previously. Patients' eye drops were placed in prescription vial(s) at baseline with Medication Event Monitoring System caps to electronically measure adherence over a 12-month period. RESULTS: Patients in the intervention group who asked any questions at baseline or 6 months were significantly more likely to take the percentage of correct number of doses each day during the 12-month follow-up period than patients in the intervention group who did not ask any questions (35% compared with 16%, p=0.0004). The video/question prompt list intervention was not significantly associated with whether patients were 80% or more adherent during the 12-month follow-up period. CONCLUSIONS: An interesting finding was that Black patients in the intervention group who asked any questions during visits were more likely to take the percentage of correct prescribed doses each day and the percentage of correct number of doses each day on schedule over a 12-month period than those in the intervention group who did not ask any questions. Future work needs to figure out ways to motivate more patients who receive the question prompt list/video intervention to ask questions during their visits.
