Automated patient care system and method for diagnosing and monitoring respiratory insufficiency
First Claim
1. An automated collection and analysis patient care system for diagnosing and monitoring respiratory insufficiency and outcomes thereof, comprising:
- a database storing patient monitoring information, comprising;
a plurality of monitoring sets, each monitoring set comprising recorded measures which each relate to patient information and comprise either medical device measures or derived measures calculable therefrom, the medical device measures having been recorded on a substantially continuous basis;
a set of stored indicator thresholds, each indicator threshold corresponding to a quantifiable physiological measure of a pathophysiology indicative of respiratory insufficiency and relating to a same type of patient information as at least one of the recorded measures, the database further storing a reference baseline comprising recorded measures which each relate to patient information recorded by the medical device adapted to be implanted during an initial time period and comprise either device measures recorded by the medical device adapted to be implanted or derived measures calculable therefrom, and recorded measures relating to patient information for one of the individual patients solely, a peer group of patients to which the individual patient belongs, and a general population of patients;
a server diagnosing a respiratory insufficiency finding, comprising;
an analysis module determining a change in patient wellness by comparing at least one recorded measure to at least one other recorded measure with both recorded measures relating to the same type of patient information; and
a comparison module comparing each patient wellness change to at least one of the stored indicator thresholds corresponding to the same type of patient information as the recorded measures which were compared; and
a database module obtaining at least one of the at least one recorded measure and the at least one other recorded measure from the retrieved reference baseline.

Abstract
An automated patient care system and method for diagnosing and monitoring respiratory insufficiency is presented. A plurality of monitoring sets are stored into a database. Each monitoring set includes recorded measures, which each relate to patient information and contain medical device measures recorded on a substantially continuous basis or derived measures calculable therefrom. The monitoring sets are retrieved from the database. A set of indicator thresholds are defined. Each indicator threshold corresponds to a quantifiable physiological measure of a pathophysiology indicative of respiratory insufficiency. A respiratory insufficiency finding is diagnosed. A change in patient status is determined by comparing at least one recorded measure to at least one other recorded measure with both recorded measures relating to the same type of patient information. Each patient status change is compared to the indicator threshold corresponding to the same type of patient information as the recorded measures.
