First Claim
Patent Images
1. A heart failure hospitalization management system, comprising:
- one or more sensors to sense one or more physiological signals;
a sensor processing circuit, coupled to the one or more sensors, to produce sensor data representative of the sensed one or more physiological signals; and
a heart failure analyzer coupled to the sensor processing circuit, the heart failure analyzer including;
a data input adapted to receive diagnostic data indicative of one or more conditions associated with heart failure, the data input including a sensor data input configured to receive the sensor data;
a diagnostic data processor adapted to produce one or more parameters using the diagnostic data;
a mode switch adapted to switch an operational mode of the heart failure analyzer to a hospitalization mode in response to a mode-change command; and
a risk analyzer adapted to produce a risk class parameter during the hospitalization mode, the risk class parameter classifying a level of risk for rehospitalization within a specified period using the one or more parameters.

Abstract
A hospitalization management system including a heart failure analyzer that receives diagnostic data including at least sensor data representative of one or more physiological signals sensed from a hospitalized patient using one or more sensors and assesses risk of rehospitalization for the patient using the diagnostic data. The outcome of the risk assessment is used during and following the patient'"'"'s hospitalization for reducing the risk of rehospitalization.
