1. A medical modeling system for predicting a risk of a physiological condition for a patient, said medical modeling system comprising: at least one processor programmed to: receive measurements of a plurality of predictive variables for the patient, the plurality of predictive variables predictive of the risk of the physiological condition; calculate the risk of the physiological condition by applying the received measurements to at least one model modeling the risk of the physiological condition using the plurality of predictive variables, the at least one model including at least one of a hidden Markov model and a logistic regression model; and output an indication of the risk of the physiological condition to a clinician.
