A Previsit Intervention's Influence on Glaucoma Topics Discussed between Black Patients and Providers

Purpose: The objectives of this study were to conduct a randomized controlled trial testing the effectiveness of a previsit glaucoma video/question prompt list intervention, and to examine the impact on how often providers educate Black patients about glaucoma and glaucoma medication topics during visits. Design: A randomized controlled trial of a glaucoma question prompt list/video intervention. Participants: Black patients with a diagnosis of glaucoma who are taking 1 or more glaucoma medications and report being nonadherent. Methods: One hundred eighty-nine Black patients with glaucoma were enrolled and assigned to either a usual care or an intervention group where they watched a video emphasizing the importance of asking questions and received a glaucoma question prompt list to complete before clinic visits. Visits were audio-taped and patients were interviewed after visits. Main Outcome Measures: Whether the provider educates about different glaucoma and glaucoma medication topics. Results: Patients in the intervention group were significantly more likely to ask providers 1 or more questions about glaucoma and its treatment. Providers were significantly more likely to educate intervention patients about their diagnosis (P = 0.001), intraocular pressure (P = 0.03), the likelihood of the need for long-term therapy (P = 0.001), and the physical changes associated with glaucoma (P = 0.001) than usual-care patients. Providers were also significantly more likely to educate intervention patients about the purpose of their medications (P = 0.03) and side effects (P = 0.001) than usual-care patients. Providers only educated 29% of patients about adherence (33% of intervention group patients and 25% of usual-care patients). Few providers educated patients about barriers and fears/concerns in using glaucoma medications, the cost of medications and insurance coverage, how to administer eye drops, and nasolacrimal occlusion. Conclusions: The intervention significantly increased provider education about many glaucoma and glaucoma medication topics.
