Study Summary
The investigators are studying motivational interviewing (MI). MI is a counseling method to help people adopt healthy behaviors. The investigators will test whether MI improves patients' accurate use of glaucoma eye drops. The investigators will train eye clinic staff called glaucoma educators to use MI. Up to 250 patients at 3 clinics will be recruited. All patients will receive their usual eye care. Based on chance, some patients will also be supported by a glaucoma educator. The groups will be compared on medication adherence using micro-electro-mechanical system(MEMS). MEMS are electronic bottle caps that track when a medication bottle is opened. Patients will be aware that their medication use is tracked. The groups will also be compared on treatment value, outcomes, and cost. The investigators will also collect data on variables that may predict medication adherence.
Primary Outcome
Compare adherence and persistence between the intervention and control groups. (Medication Event Monitoring Systems)that record the date and time a pill bottle is opened we are evaluating the percentage of prescribed doses taken during ain one-week intervals, but will augment it by also considering a more fine-grained percentage of prescribed doses taken in required dosing window (defined as within 3 hours before or after the scheduled time) as a second primary outcome measure.
Interventions
- BEHAVIORAL motivational interviewing
- BEHAVIORAL three phone calls to remind patients to take their eye drops
