OBJECTIVE: In the Medication Adherence In Glaucoma To Improve Care trial, 200 veterans with medically-treated glaucoma were randomized to an intervention designed to improve glaucoma medication adherence or to usual care. In the 6 months after intervention, the mean proportion of doses taken on schedule was higher for participants in the intervention group compared with controls (0.85 vs. 0.62, P < 0.001). The purpose of this study was to use a mixed-methods approach to compare barriers and facilitators with adherence among participants through qualitative analysis of structured interviews. DESIGN: This is an analysis of interviews conducted from patients participating in a clinical trial. PARTICIPANTS: Participants from the intervention arm were separated into quartiles based on medication adherence according to the electronic monitor to sample from high and low responders to the intervention. We interviewed 23 participants; 11 participants with low adherence and 12 with high adherence. METHODS: Interviews were conducted over telephone and transcribed. Staff members used grounded theory to conduct content analysis and code the transcribed interviews. The iterative process produced categories of common barriers and facilitators for medication adherence. MAIN OUTCOME MEASURES: The frequency of responses addressing common barriers and facilitators were compared between participants with high and low adherence. RESULTS: In the lowest- and highest-adherence groups, a difficult schedule was the most cited barrier for regular drop usage (63.6% and 58.3%, respectively). In the lowest and highest-adherence groups, the most cited facilitator for adherence was use of the smart bottle (100% and 91.7%, respectively). In the lowest-adherence group, 72.7% of participants cited that improved ability to administer drops was a benefit from the intervention. In the highest-adherence group, 75% of participants cited increased disease knowledge and formation of habits as facilitators from the intervention. Of the 22 of 23 participants who mentioned the smart bottle, 100% cited that they had increased adherence and would continue using the smart bottle. CONCLUSIONS: Using dosing reminders and personalized patient education may be important avenues for addressing difficulties with adhering to an eye drop schedule to improve glaucoma self-management.
