1. A method for determining a patient health state compound score comprising: generating at least first and second histograms respectively for at least first and second sets of vital sign measurements using at least first and second predetermined bins, wherein the first and second sets of the vital sign measurements each include at least two measurements acquired at different times, and the first and second vital sign are different vital signs; generating a first score distribution for the first vital sign by mapping each bin of the first predetermined bins to a corresponding predetermined score; generating a second score distribution for the second vital sign by mapping each bin of the second predetermined bins to a corresponding predetermined score; and generating a compound score distribution for the first and second vital signs based on the first and second score distributions, wherein the compound score distribution indicates a health state of a patient.
