The Effect Of Patient Education And Telemedicine Reminders On Adherence To Eye Drops For Glaucoma

Purpose: To determine the improvement in patient adherence to topical ocular hypotensive therapy by introducing a personalized illustrated medication reference chart and telereminder.Design: Prospective randomized controlled clinical trial.Participants: Fifty-nine patients with glaucoma who were using at least 3 or more eye drops were recruited from the ophthalmology clinic at the National University Hospital of Singapore.Methods: Participants were randomized into 3 groups: control, reference chart only, and reference chart with telereminder. They completed a survey on demographics, barriers to glaucoma medication adherence, and self-adherence (measured by the Morisky adherence scale) before and 6 weeks after intervention. Logistic regression analysis was performed on the barriers that contribute to nonadherence and paired t tests were conducted for the preimplementation and postimplementation effects of intervention on adherence score.Main Outcome Measures: Changes in mean adherence score based on the Morisky adherence scale before and after intervention in participants from all 3 groups.Results: In our study, 71 % of participants who were nonadherent to medications had multiple barriers to adherence, with lack of self-efficacy and forgetfulness being the most common factors. Only the reference chart with telereminder group showed a statistically significant increase in mean adherence score, from 7.18 to 7.69 (P = 0.047).Conclusions: Adherence to medication in chronic diseases like glaucoma is an important healthcare issue to address. Most of these patients have poor adherence because of multiple factors, and hence interventions aimed at improving adherence should be multifaceted to target these barriers.
