Abstract

An electronic health care compliance assistance system includes a user device and a host station used by a health care provider. The user device generates voice messages to remind a user when and how to take or refill prescribed medications, to attend to other health matters, and to keep doctors'"'"' appointments. Compressed digital speech is used to generate clear and natural sounding voice messages. A health care provider uses the host station to compose messages and to store a database of speech messages and related data. Data are transferred from the host station to the user device to generate a regimen that is customized for the user. A queuing system is provided for messages relating to medications having common dosing times. A parameter is defined to permit adaptive rescheduling of messages when a user does not respond. The user device provides adaptive and interactive audible and visual prompts to alert the user when one or more messages are ready to be played. A satellite device may be used to generate such prompts to alert the user to consult the user device for the message. User operated keys are provided to play a message, to repeat the message, to confirm that the desired action has been attended to, or to play a counseling message. The user device stores data on each user action and inaction, for transfer to the host station which compiles the data in a report for health care providers.
