Embodiment Construction

[0017] Heart failure subjects are often most vulnerable to the adverse consequences of an adverse cardiac event in the first few days or weeks after hospital discharge or after a treatment event. Given recent trends in reducing provider recompensation for subjects readmitted within a specified time (e.g., 30 days) after discharge, it may be desirable to identify subjects whose health declines after discharge or at other times, and optionally initialize , adjusting or otherwise optimizing one or more treatments effective for the subject, such as by updating (eg changing) the operating characteristics of the implantable medical device.

[0018] In one example, subjects with declining health or unchanged health may be identified. For example, subjects exhibiting worsening symptoms of heart failure may be identified. In one example, one method of identifying such a subject includes tracking those aspects of the subject's clinical state or physiology that changed more than others ...

Abstract

Systems and methods for the management of subject readmission are described. In one example, multiple sensors may be used to obtain multiple physiological signals from the subject. In response to a hospitalization event, pre-hospitalization features of a plurality of physiological signals may be identified. Post-hospital features of multiple physiological signals can be identified, including features that differ from their corresponding pre-hospital features. Later, subsequent physiological signals may be further monitored after a hospitalization event, for example using the same plurality of sensors, and subsequent physiological signal characteristics may be identified. In one example, a heart failure diagnostic indicator can be determined using information about pre-hospitalization characteristics, post-hospitalization characteristics, and subsequent characteristics. Information about relative changes in signal characteristics from multiple sensors can be used to identify a particular subject's physiological signal for subsequent monitoring.

Description

[0001] claim priority [0002] This application claims the benefit of priority under 35 U.S.C § 119(e) of U.S. Provisional Patent Application Serial No. 61 / 785,451 filed March 14, 2013 and U.S. Provisional Patent Application filed July 22, 2013 The benefit of priority under 35 U.S.C § 119(e) of Serial No. 61 / 856,816, each of which is hereby claimed, is hereby incorporated by reference in its entirety. Background technique [0003] The heart is an electromechanical system that performs two main pumping functions. The left side of the heart (including the left atrium and left ventricle) takes oxygenated blood from the lungs and pumps this blood to the various organs of the body to provide them with oxygen for their metabolic needs. This pumped blood flow is called cardiac output. The right side of the heart (including the right atrium and right ventricle) takes oxygen-depleted blood from the organ and pumps it to the lungs where the blood is oxygenated. The pumping function ...
