Patient Question-Asking About Glaucoma and Glaucoma Medications During Videotaped Medical Visits

We applied the ecologic model of communication in medical consultations to examine how patient, physician, and situational/contextual factors are associated with whether patients ask one or more questions about glaucoma and glaucoma medications during visits to ophthalmologists. Patients with glaucoma who were newly prescribed or already on glaucoma medications were recruited at six ophthalmology clinics. Patients’ visits with their doctors were video-recorded and patients were interviewed after visits. Generalized estimating equations were used to analyze the data. Two hundred and seventy-nine patients participated. Patients asked one or more questions about glaucoma during 59% of visits and about glaucoma medications during 48% of visits. Patients who were newly prescribed glaucoma medications were significantly more likely to ask one or more questions about glaucoma and glaucoma medications. Whether providers asked patients if they had questions was not significantly associated with patient question-asking. Patients were significantly more likely to ask older providers questions about glaucoma medications and female providers questions about glaucoma. Eye care providers should encourage glaucoma patients to ask questions during their medical visits.
