1. At a computer system, a method for detecting a support platform exiting event, the method comprising:

  • accessing movement data from sensors that are monitoring a patient resting on a support platform, the movement data indicative of movement in one or more portions of the patient'"'"'s body;

    generating a motion capture pattern summary for the patient from the accessed movement data, the motion capture pattern summary capturing movements for the one or more portions of the patient'"'"'s body;

    comparing the motion capture pattern summary to one or more movement pattern data sets in a library of movement pattern data sets, the one or more movement pattern data sets in the library of movement pattern data sets being representative of movements having some probability of indicating platform support exiting;

    determining that the motion capture pattern summary is sufficiently similar to one of the one or more movement pattern data sets in the library of movement pattern data sets; and

    detecting that the patient is attempting to exit the support platform based on the determined similarity by;

    accessing a general probability factor corresponding to the one or more movement pattern data sets, the general probability factor generally indicative of the probability of the detected movement corresponding to a support platform exiting event;

    accessing a behavioral weighting factor for the patient, the value of the behavioral weighting factor based on prior detections of movement pattern data sets confirmed as support platform exiting attempts by the patient;

    combining the probability factor and the behavioral weighting factor into a patient specific probability factor; and

    determining that the patient specified probability factor satisfies a configured probability threshold indicative of a support platform exiting event.
