METHODS AND SYSTEMS FOR MONITORING PATIENT SUPPORT EXITING AND INITIATING RESPONSE
First Claim
1. In a facility that includes a plurality of patients, a support upon which each patient rests at least some of the time, and a computer-controlled system for monitoring positions and/or movements of the patients that are predictive of patient support exiting and providing an appropriate response thereto, a method for monitoring a patient while resting on a support and determining whether the patient is likely preparing to exit the support, comprising:
- accessing by a computer system a patient profile associated with the patient being monitored from among a plurality of different patient profiles corresponding to different patients, the patient profile including data relating to at least one position and/or movement of the patient that is predictive of support exiting by the patient and that differs from profile data relating to support exiting by at least one other patient;
the computer system generating and/or receiving a data stream representative of one or more positions and/or movements of the patient;
the computer system comparing the data stream representative of one or more positions and/or movements of the patient and comparing it with patient profile data that has been predetermined to be predictive of support exiting by the patient being monitored; and
initiating a response in order to prevent or mitigate harm to the patient upon finding a correlation between the data stream representative of one or more positions and/or movements of the patient and the patient profile data that has been predetermined to be predictive of support exiting by the patient being monitored.

Abstract
Methods, systems and computer program products for monitoring patient support exiting and initiating a response to prevent or mitigate harm. One ore more cameras provide a video data stream of a patient resting on a bed, chair, wheelchair, gurney, recliner or other support. A computer system analyses the video data stream and determines the location and/or movements of the patient relative to a fixed reference (e.g., the support). A profile containing personalized support exiting data for the patient is used to accurately predict support exiting. Intervention to prevent or mitigate harm in the event support exiting is detected may include an alarm, audio/visual communication and/or direct physical intervention. Patient profiles can be updated in response to observed behavior to better predict support exiting.

2. In a computer-controlled system for monitoring one or more positions and/or movements of a patient on a support that are predictive of patient support exiting and providing an appropriate response thereto, a method for monitoring the patient while resting on the support and determining whether the patient is likely preparing to exit the support, comprising:
-
a computer system accessing a patient profile associated with the patient being monitored that includes data relating to at least one position and/or movement of the patient that has been predetermined to be predictive of support exiting by the patient;
the computer system receiving a video data stream of the patient while resting on the support;
the computer system analyzing the video data stream, determining at least one position and/or movement of the patient from the video data stream, and comparing the at least one position and/or movement of the patient determined from the video data stream with patient profile data that has been predetermined to be predictive of support exiting by the patient; and
the computer system initiating a response in order to prevent or mitigate harm to the patient upon finding a correlation between the at least one position and/or movement of the patient determined from the video data stream and the patient profile data. - View Dependent Claims (3, 11, 12, 23)

24. In a facility that includes a plurality of patients, supports upon which the patients rest at least some of the time, and a computer-controlled system for monitoring one or more positions and/or movements of each patient that are predictive of patient support exiting and providing an appropriate response thereto, a method for monitoring the plurality of patients while resting on the supports and determining whether one or more of the patients are likely preparing to exit a support, comprising:
-
inputting into a computer system a plurality of patient profiles that include data relating to at least one position and/or movement of each patient that has been predetermined to be predictive of support exiting by that patient, at least two of the patient profiles differing with respect to data relating to predicted support exiting in order to more accurately distinguish, as between different patients, behavior that is predictive of support exiting from non support exiting behavior;
sending video data streams of two or more patients while resting on respective supports to the computer system;
the computer system analyzing the video data streams, determining at least one position and/or movement of each patient from the video data streams, and comparing the at least one position and/or movement of each patient determined from the video data streams with corresponding patient profile data that has been predetermined to be predictive of support exiting by that patient; and
initiating a response in order to prevent or mitigate harm to a patient upon finding a correlation between the at least one position and/or movement of the patient determined from the video data stream and patient profile data corresponding to the patient. - View Dependent Claims (25, 27)

26. In a facility that includes a patient, a bed upon which the patient rests at least some of the time, and a computer-controlled system for monitoring one or more positions and/or movements of the patient that are predictive of patient bed exiting and providing an appropriate response thereto, a method for monitoring the patient while resting on the bed and determining whether the patient is likely preparing to exit the bed, comprising:
-
inputting into a computer system a patient profile associated with the patient being monitored that includes data relating to one or more of the following movements that are predictive of potential bed exiting by the patient;
