Compliance devices preferred by elderly patients.

Many elderly patients take several medications for chronic conditions, a situation which causes problems in compliance with drug regimens. This study surveyed patients' preferences among four devices designed to make compliance easier: rub-off reminder labels, medication organizer trays, a container cap with a modified alarm clock, and a digital elapsed timer. Thirty-one enrolled patients used each device for one month then reported their ratings of four device attributes--clarity of directions for use, ease of use, convenience, and effectiveness in preventing dosing errors. The patients showed a strong preference for the medication organizer tray and generally preferred less-complex devices to those that were more difficult to learn to use.
