SYSTEMS AND METHODS FOR TRANSITIONING PATIENT CARE FROM SIGNAL-BASED MONITORING TO RISK-BASED MONITORING
First Claim
1. A computer-implemented method for risk-based monitoring of patients, comprising:
- acquiring, with a computer, data associated with a plurality of the internal state variables each describing a parameter physiologically relevant to at least one of a treatment and a condition of a patient;
storing, in a computer accessible memory, the acquired data associated with the plurality of the internal state variables;
generating, with a computer, estimated probability density functions for the plurality of the internal state variables;
identifying, with a computer, from the generated probability density functions of the internal state variables, into which of a first plurality of possible patient states the patient is currently categorizable and;
generating a probability value associated with each identified possible patient state.

Abstract
A risk-based patient monitoring system for critical care patients combines data from multiple sources to assess the current and the future risks to the patient, thereby enabling providers to review a current patient risk profile and to continuously track a clinical trajectory. A physiology observer module in the system utilizes multiple measurements to estimate Probability Density Functions (PDF) of a number of Internal State Variables (ISVs) that describe a components of the physiology relevant to the patient treatment and condition. A clinical trajectory interpreter module in the system utilizes the estimated PDFs of ISVs to identify under which probable patient states the patient can be currently categorized and assign a probability value that the patient will be in each of the identified states. The combination of patient states and their probabilities is defined as the clinical risk to the patient.
