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.
Claims20
A system for managing a heart failure patient, comprising:
- a sensor data input configured to receive sensor data representative of one or more physiological signals, the one or more physiological signals including a heart sound signal;
- and
- a heart failure management circuit configured to:
- analyze the sensor data;
- generate a rehospitalization alarm in response to a need for rehospitalization indicated by the analysis of the sensor data during a post-hospitalization period after a hospitalization of the patient;
- and
- generate a hospitalization alarm in response to a need for hospitalization indicated by the analysis of the sensor data outside of the post-hospitalization period.
A method of heart failure hospitalization management, comprising:
- receiving sensor data representative of one or more physiological signals, the one or more physiological signals including a heart sound signal;
- analyzing the sensor data;
- timing a post-hospitalization period after a hospitalization of a patient;
- generating a rehospitalization alarm in response to a need for rehospitalization indicated by the analysis of the sensor data during the post-hospitalization period;
- and
- generating a hospitalization alarm in response to a need for hospitalization indicated by the analysis of the sensor data outside of the post-hospitalization period.
