Method of continuous prediction of patient severity of illness, mortality, and length of stay
First Claim
1. A patient monitoring system comprising:
- a patient monitor device which collects physiological data from a patient;
a control processor configured to;
receive the collected physiological data from the patient monitor device,receive laboratory data about the patient from a laboratory,determine a time of stay indicative of a time the patient has been in a healthcare facility,predict an outcome variable continuously in real time by applying an outcome variable estimation algorithm to the patient'"'"'s physiological and 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.
