Abstract

A system and method for automated collection and analysis of patient information retrieved from a medical device adapted to be implanted in a patient for remote patient care is described. A set of collected measures is periodically received from the medical device adapted to be implanted over a communications link which is interfaced to a network server. The collected measures set includes individual measures which each relate to patient information recorded by the medical device adapted to be implanted for an individual patient. The collected measures set is stored into a patient care record for the individual patient within a database server organized to store one or more patient care records. Each patient care record includes a plurality of the collected measures sets. One or more of the collected measures sets in the patient care record for the individual patient is analyzed relative to one or more other collected measures sets stored in the database server to determine a patient status indicator.
