Therapeutic decisions systems and method using stochastic techniques
First Claim
1. A system comprising:
- a monitoring device monitoring a plurality of physiological signals of a current patient;
a database, which stores records indicative of a plurality of patients including at least some of said physiological signals for said plurality of patients and prognosis information for said plurality of patients;
a processor, comparing said physiological signals to said stored records in a database, to determine mathematically patients in the database which are most similar to a current patient; and
to make available information about treatment and results for said patients who are most similar to the current patient.

Abstract
Patients are evaluated in terms of various physiological parameters such as hemodynamic parameters. Covariate information indicative of the patient'"'"'s individual characteristics may also be determined. A state variable indicative of the patient'"'"'s characteristics is determined. This state variable is used to compare the patient to other patients in the database. The other patients in the database are evaluated in terms of similar parameters and their probability of survival as well as different treatments and the probability of survival based on those different treatments. The patient may be simply evaluated based on the database or a proper course of treatments may be determined based on the database.

18. A method, comprising:
-
monitoring a plurality of physiological signals of a current patient;
comparing said physiological signals of the current patient to stored physiological signals for previous patients stored in a database;
determining patients in said database who are most similar to the current patient; and
determining information about treatments and results for said patients who are most similar to the current patient. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A method, comprising:
-
determining hemodynamic parameters of an individual patient;
determining covariate parameters of the individual patient representing the patients individual characteristics;
using said covariate characteristics and said hemodynamic parameters to develop a state variable that represents information that is continuously variable in time;
comparing said state variable with information indicative of a plurality of previously treated patients in the database; and
obtaining survival information about said patients in said database.
