SYSTEM AND METHOD FOR HEART FAILURE PREDICTION
First Claim
1. A method for monitoring a health status of a human subject, comprising the steps of:
- capturing medical data concerning the health of the subject at defined intervals using a questionnaire, wherein the questionnaire provides a standard script for data capture, wherein a first part of the questionnaire has a first portion of the captured data on a Likert scale and a second portion on a visual analog scale, and wherein a second part of the questionnaire has the captured data in the form of an assessment by a physician of health symptoms of the subject;
inputting the captured data into a computer;
extracting a calibrated value corresponding to the second portion of the captured data from the visual analog scale using a tool;
providing the captured data and the calibrated value to an algorithm configured to assess a risk of acute heart failure;
computing the risk of acute heart failure by executing the algorithm in the computer using the captured data input from a plurality of the defined intervals and using calibrated values associated with each of the plurality of the defined intervals; and
outputting to the physician the health status as being either improved or worsening as a function of a value of the computed risk.

Abstract
Monitoring a health status of a human subject at defined intervals using a questionnaire. The questionnaire provides a standard script for capture, including data from a patient entered on a visual analog scale (VAS). A tool accurately assesses entries on the VAS for use by an algorithm. The captured data is input into a computer together with a physician assessment of health symptoms of the subject and provided to the algorithm for an assessment of a risk of acute heart failure of the subject. The risk is computed using the algorithm and captured data from a plurality of defined intervals. In one method, the health status of the subject as being either improved or worsening is output to the physician as a function of a value of the computed risk. In another method, a survival function outcome for the subject is predicted using the output of the algorithm.
