Abstract

A system and a method for providing normalized voice feedback from an individual patient in an automated collection and analysis patient care system are described. A set of device measures from a medical device adapted to be implanted is collected. The collected device measures set includes individual device measures which each relate to patient information recorded by the implantable medical device for the individual patient. The collected measures set from the implantable medical device are periodically received over a communications link which is interfaced to a network server and stored into a patient care record within a database server. The database server is organized to store one or more patient care records which each include a plurality of the collected measures sets. Voice feedback is spoken by the individual patient into a remote client substantially contemporaneous to the collection of an identifiable measures set. The voice feedback is processed into a set of quality of life (QOL) measures which each relate to patient self-assessment indicators. The identified collected measures set and the QOL measures set are received over the communications link respectively from the implantable medical device and the remote client and stored into the patient care record. The identified collected measures set, the QOL measures set, and one or more of the collected measures sets in the patient care record for the individual patient are analyzed relative to one or more other collected measures sets stored in the database server to determine a patient status indicator.
