TREATMENT FOR GLAUCOMA - ADHERENCE BY THE ELDERLY

Objectives. The purpose of this study was to determine the extent of n onadherence to treatment for glaucoma among elderly patients. Methods. This was a retrospective cohort study of 2440 patients older than age 65 who were enrolled in the New Jersey Medicaid Program and who were newly initiated on a topical agent for the treatment of glaucoma. Two patient-specific measures of nonadherence were employed: (1) no filled prescription for any glaucoma medication over a 12-month period after the initiation of therapy and (2) number of days without therapy for glaucoma during this 12-month period. Results. By the first measure, 5 69 patients (23%) were found to be nonadherent. The mean number of day s without therapy during the study year was 112. Factors associated wi th nonadherence included the use of glaucoma medication requiring more than 2 administrations per day and the presence of multiple other med ications in the patient's drug regimen. Patients started on multiple g laucoma medications were more adherent than those started on a single agent. Age and sex were not found to be predictors of nonadherence. Co nclusions. Substantial nonadherence was found to be common in this pop ulation. More attention to the issue of nonadherence could result in i mportant benefits in the preservation of sight.
