Published on June 13, 2012 at 5:29 AM A telephone intervention trial was associated with improvement in glaucoma medication adherence in both the treatment group and the control group but, when the two groups were compared, interactive telephone calls and tailored print materials did not significantly improve adherence, according to a report of a randomized controlled clinical trial published Online First by Archives of Ophthalmology, a JAMA Network publication. Glaucoma affects more than 2 million adults over the age of 40 in the United States. While medication can reduce the visual field loss caused by this progressive disease, nonadherence by patients to their medication regimen is a treatment challenge and regular follow-up medical appointments are crucial, according to the study background. Karen Glanz, Ph.D., M.P.H., of the University of Pennsylvania, Philadelphia, and colleagues enrolled 312 patients with glaucoma in a randomized controlled trial at two eye clinics at a Veterans Affairs hospital and a large public hospital. The patients (average age nearly 63 years) were considered to be nonadherent because they did not take their medication, refill their medicine and/or keep their medical appointments. Patients were divided into either the treatment or control group. The treatment group received automated, interactive telephone calls and tailored printed materials, while the control group received usual care, which included the recommendation for medical appointments and medication refills. Researchers measured adherence to medication taking, prescription refills and appointment keeping based on interviews, medical charts and other data.
