  • Publication number: 20230419058
    Abstract: A computer-implemented system and method for entity tracking and identification is provided. A tracker associated with an entity is tracked. Communication is continuously attempted between the tracker and a tracking device associated with an individual in custody of the entity. During one of the attempted communications, an absence of the tracker is determined by identifying a time of the attempted communication and applying a time threshold to the time for the attempted communication. The absence of the tracker is identified when no communication has been established with the tracking device within the time threshold. The entity is classified as missing when the absence of the tracker is determined.

    Abstract: A computer-implemented system and method for tracking patient location is provided. A tracker associated with a patient to be tracked is monitored within a hospital. An identifier of a tracker is associated with identification information for the patient. A location of the patient is determined at predetermined times or on a continuous basis based on a location of the tracker. The determined locations are stored with times at which the locations were determined as a location history for the patient. A request for a location of the patient is received and a currently determined location or a most recent location from the history is provided as the location for the patient, in response to the request.
