Summary

The purpose of this research study is to see if a lottery which provides the opportunity to win money, a reminder system using a "Med-eMonitor", or the combination of both might be useful in helping patients to achieve better control of their anticoagulation therapy. Selection for the arms of the study is randomized by the study computer. Some will participate in the daily lottery only, some with the reminder system only, some with the reminder system and the daily lottery, and some with neither the lottery nor the reminder system.

BEHAVIORAL

Financial Incentive and Med-eMonitor

Financial Incentives: Study participants are entered into a daily lottery. It includes a chance to win either $10 or $100 on any given day throughout the participant's duration in the study (6 months). Participants are assigned a number and each day a computer randomly draws a winning number. Participants whose number is drawn can only collect money if they have taken the medication correctly. Med-eMonitor: The Med-eMonitor is a device used to measure medication compliance. The device has 5 drawers in which the participants' medication is placed. When a drawer opens, a message displays on the monitor, and asks the participant if he/she is taking his/her medication for the day. The device registers their answers and sends the compliance information via the participants' telephone line nightly to a central study server.
