1. A system for determining the risk of a patient falling after exiting a bed, the system comprising:
a bed including a bed sensor therein for monitoring a bed that is occupied by a patient;
a depth camera for imaging said patient; and
a computer running appropriate software to:
determine movement specifics of how said patient moves immediately prior to exiting said bed from both said bed sensor and said depth camera, said movement specifics including at least an amount of time it takes said patient to go from a prone to a sitting position obtained from at least one of said bed sensor or said depth camera;
based on said movement specifics, evaluate a patient's instantaneous risk of falling after exiting said bed; and
if said instantaneous risk is sufficiently high, issuing an alert for said patient.
