Methods of assessing risk based on medical data and uses thereof
First Claim
1. A method of assessing risk associated with medical data comprising:
- creating, by a computer, a dataset representing a plurality of patients, the dataset comprising (x,y) pairs for each patient, such that x represents the medical data collected at a first time, y is an outcome measurement collected at a second time, and the collected medical data is selected from one of a continuous variable or an ordinal score;
binning, by a computer, the (x,y) pairs to form a plurality of binned data sets;
computing, by a computer, an average value for x and an average value for y for each binned data set;
determining, by a computer, a minimum average value of y based on all of the average values of y;
subtracting, by a computer, the minimum average value of y from each average value of y to get a new average value of y for each binned data set; and
deriving, by a computer, a first function for assessing risk associated with the medical data, such that the first function is defined from a minimum average value of x to a maximum average value of x;
deriving, by a computer, a second function for assessing risk associated with values of x less than the minimum average value of x; and
deriving, by a computer, a third function for assessing risk associated with values of x and greater than the maximum average value of x,wherein the derived functions are used in calculating the risk associated with the medical data.

Abstract
Methods of assessing risk based on medical data are disclosed herein. In an embodiment, a method of assessing risk associated with medical data includes creating a dataset representing a plurality of patients, the dataset comprising (x,y) pairs for each patient, wherein x represents the medical data collected at a first time, and wherein y is an outcome measurement collected at a second time; binning the (x,y) pairs to form a plurality of binned data sets; computing an average value for x and an average value for y for each binned data set; determining a minimum average value of y based on all of the average values of y; subtracting the minimum average value of y from each average value of y to get a new average value of y for each binned data set; and deriving a function for assessing risk associated with the medical data.

10. A method of determining an overall risk in a patient'"'"'s current condition comprising:
-
receiving, by a computer, a plurality of medical data about a patient at a plurality of time points over a period of time, such that the received medical data includes continuous variables; converting, by a computer, each of the admitted patient'"'"'s medical data for each of the plurality of time points to values using a set of functions, wherein each of the functions defines risk associated with each of the medical data, and wherein the set of functions for each of the medical data is derived by; creating, by a computer, a dataset representing a plurality of discharged patients, the dataset comprising (x,y) pairs for each discharged patient, such that x represents a single type of medical data collected at a first point in time and y is an outcome measurement collected at a second point in time; binning, by a computer, the (x,y) pairs to form a plurality of binned data sets; computing, by a computer, an average value for x and an average value for y for each binned data set; determining, by a computer, a minimum average value of y based on all of the average values of y; subtracting, by a computer, the minimum average value of y from each average value of y to get a new average value of y for each binned data set; deriving, by a computer, a first function for assessing risk associated with the medical data, such that the first function is defined from a minimum average value of x to a maximum average value of x; deriving, by a computer, a second function for assessing risk associated with values of x less than the minimum average value of x; and deriving, by a computer, a third function for assessing risk associated with values of x and greater than the maximum average value of x; combining, by a computer, for each of the plurality of time points, the values; generating, by a computer, a Health Score from the combined values for each of the plurality of time points, each Health Score representing the patient'"'"'s health; and continually displaying, by a computer, a graph of each of the Health Scores, wherein the derived functions are used in calculating the overall risk in the patient'"'"'s current condition. - View Dependent Claims (11, 12, 18, 19, 20, 21)

13. A method of defining excess risk associated with medical data comprising:
-
creating, by a computer, a dataset representing a plurality of patients, the dataset comprising (x,y) pairs for each patient, such that x represents a pass or a fail score of a nursing assessment collected at a first point in time and y is an outcome measurement collected at a second point in time; binning, by a computer, the (x,y) pairs to form two binned data sets; computing, by a computer, an average value for y for each binned data set; determining, by a computer, a minimum average value of y based on all of the average values of y; subtracting, by a computer, the minimum average value of y from each average value of y to get a new average value of y for each binned data set; and calculating, by a computer, a function for defining excess risk associated with the failing of the nursing assessment, wherein the calculated function is used in determining the excess risk associated with the medical data. - View Dependent Claims (14, 15, 16, 17)

23. A method of defining excess risk associated with medical data comprising:
-
creating, by a computer, a dataset representing a plurality of patients, the dataset comprising (x,y) pairs for each patient, such that x represents a categorical class determined at a first time and y is an outcome measurement collected at a second time; binning, by a computer, the (x,y) pairs to form a plurality of binned data sets; computing, by a computer, an average value for y for each binned data set; subtracting, by a computer, the minimum average value of y from each average value of y to get a new average value of y for each binned data set; and calculating, by a computer, a function for defining excess risk associated with the categorical class, wherein the calculated function is used in determining the excess risk associated with the medical data. - View Dependent Claims (24, 25)
