The TRAVATAN dosing aid accurately records when drops are taken

center dot PURPOSE: To assess the accuracy of Travatan Dosing Aid recordings. center dot DESIGN: Prospective evaluation of drop-recording accuracy. center dot METHODS: Physicians and patients used the Dosing Aid, and logs of usage were compared to the data obtained from the Dosing Aid. center dot RESULTS: Five physicians and 20 patients participated. Devices used by physicians recorded all drops dispensed. Extra readings were recorded when physicians carried the devices during the day. For patients, 93% of all drops were recorded, with 18 of 20 subjects having over 85% of the drops recorded. Seventy percent of patients would continue using the device. center dot CONCLUSIONS: The Dosing Aid accurately recorded most eyedrops administered by patients and physicians. Given recent documentation of widespread undercompliance with medical therapy, the Dosing Aid could be a useful addition to clinical practice and research.
