Patent ID: 8417541

Claim:
One or more non-transitory computer-storage media having computer-executable instructions embodied thereon for performing a method in a clinical computing environment for predicting a probability of mortality for a patient admitted to an Intensive Care Unit, the method comprising: determining a length of a first Intensive-Care-Unit-day for the patient; calculating a first mortality probability utilizing a first mortality prediction model, the first mortality prediction model being based on physiological data items collected within the patient's first Intensive-Care-Unit-day; calculating a second mortality probability utilizing a second mortality prediction model, the second mortality prediction model being based on clinical data items collected within one hour of the patient being admitted to the Intensive Care Unit; determining a difference between the second mortality probability and the first mortality probability; calculating the probability of mortality for the patient utilizing Equation 1: e Yi /(1 +e Yi ), wherein Y i is calculated utilizing Equation 2: Y i =β 0 +(β 1 )( A )+(β 2 )(λ)+(β 3 )(δ (MA) ), wherein Y i equals zero if the patient survives and one if the patient dies, wherein A equals the logit of the first mortality probability, wherein λ equals the length of the first Intensive-Care-Unit-day, wherein δ (MA) equals one if the difference between the second mortality probability and the first mortality probability exceeds 0.15 and zero if the difference between the second mortality probability and the first mortality probability is less than or equal to 0.15, and wherein values for β 0 , β 1 , β 2 , and β 3 are obtained through a logistic regression procedure using Equation 2; and assessing ICU performance by comparing observed and predicted mortality.
