WITHIN-PATIENT ALGORITHM TO PREDICT HEART FAILURE DECOMPENSATION
First Claim
Patent Images
1. A method comprising:
- detecting an alert status of one or more detectors, the alert status being indicative of a first event occurring in a first timeframe;
calculating an alert score at by combining the alert status of the one or more sensors;
calculating a composite alert score, the composite alert score being indicative of a likelihood of an onset of a physiological condition and comprising a combination of two or more alert scores;
comparing the composite alert score to a composite alert score threshold; and
providing an indication of the likelihood of the onset of the physiological condition when the composite alert score violates the composite alert score threshold.

Abstract
This document discusses, among other things, systems and methods for predicting heart failure decompensation using within-patient diagnostics. A method comprises detecting an alert status of each of one or more sensors; calculating an alert score by combining the detected alerts; and calculating a composite alert score, the composite alert score being indicative of a physiological condition and comprising a combination of two or more alert scores.

12. A system comprising:
a patient device comprising; a communication module adapted to detect an alert status of one or more detectors, the alert status being indicative of a first event occurring in a first timeframe; and an analysis module adapted to; calculate an alert score by combining the detected alerts; calculate a composite alert score, the composite alert score being indicative of a likelihood an onset of a physiological condition and comprising a combination of two or more alert scores; and compare the composite alert score to a composite alert score threshold to obtain a result; wherein the communication module is adapted to provide an indication of the likelihood of the onset of a physiological condition when the result indicates that the composite alert score violates the composite alert score threshold. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A machine-readable medium including instructions, which when executed on a machine, cause the machine to:
-
detect an alert status of one or more detectors, the alert status being indicative of a first event occurring in a first timeframe; calculate an alert score at by combining the alert status of the one or more sensors; calculate a composite alert score, the composite alert score being indicative of a likelihood of an onset of a physiological condition and comprising a combination of two or more alert scores; compare the composite alert score to a composite alert score threshold; and provide an indication of the likelihood of the onset of the physiological condition when the composite alert score violates the composite alert score threshold.
