METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR EVALUATING A HOSPITAL PATIENT'S RISK OF MORTALITY

摘要

The subject matter includes methods, systems, and computer readable media for evaluating a hospital patient's risk of mortality. According to one aspect of the subject matter described herein, a method for evaluating a hospital patient's risk of mortality is provided. The method includes collecting data from physiologic signals generated by patient monitors, physiologic signals of organ function, and demographic information for a patient. The method further includes determining a measure of the variability of at least one of the physiologic signals. The method further includes analyzing data and the measure of variability to determine whether a value for a particular physiologic or demographic variable falls within a critical interval for the variable that indicates that the value is predictive of mortality or survival. Each time a value for a physiological or demographic variable for the patient falls within a critical interval, the method includes recording the occurrence of an event for the patient. The method further includes counting the number of events for the patient over a time period. The method further includes, generating, based on the account output perceptible by human user that indicates the patient's risk of mortality or likelihood of survival.
