Patent ID: 8355925

Claim:
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.
