METHOD OF CONTINUOUS PREDICTION OF PATIENT SEVERITY OF ILLNESS, MORTALITY, AND LENGTH OF STAY
First Claim
1. A patient information device comprising:
- a controller which receives physiological and/or laboratory data about a current patient from a patient monitoring device;
a unit which determines a time of stay indicative of a time that the current patient has been under care; and
a prediction unit which predicts an outcome variable by applying an outcome variable estimation algorithm to the current patient'"'"'s physiological and/or laboratory data using the determined time of stay,

Abstract
A method for predicting a patient'"'"'s outcome variable, such as a probability of mortality/recovery, includes accessing at least one of a plurality past patients'"'"' data fields including physiological and/or laboratory data, and a time of stay indicating how long each patient had been under care at the time. An outcome variable estimation algorithm is generated by data mining from a plurality of past patients'"'"' physiological and/or laboratory data, corresponding time of stay, and associated outcome variables. A current patient'"'"'s outcome variable is determined from the current patient'"'"'s physiological and/or laboratory data, the current time of stay, and the outcome variable estimation algorithm.
