1. A system for monitoring and responding to predefined movements of a monitored person within premises occupied by the person, comprising:

  • one or more RFID tags carried by the person including at least one upper-body RFID tag and at least one lower-body RFID tag;

    one or more RFID antennas located in the premises including at least one RFID floor antenna associated with flooring in the premise, at least one RFID bed antenna associated with a bed assigned to the person for sleeping within the premises, and at least one RFID door antenna associated with a door providing egress to the premises;

    one or more RFID transceivers configured to generate interrogation signals for transmission from the RFID antennas to the RFID tags and receive reply signals generated by the RFID tags in response to the interrogation signals;

    one or more controllers configured to analyze the reply signals received from the RFID tags and determine whether the person has engaged in predefined movements based on the reply signals, wherein the predefined movements include a fall from which the person has not recovered, bed egress, wandering, attempted or actual room egress, and medication access; and

    one or more response systems configured to implement one or more response actions in response to a determination that the person has engaged in one or more of the predefined movements, wherein the response actions include delivery of an alert message to a patient monitoring system, activation of a camera associated with the premises, activation of an announcement that is audible within the premises, and detection of an RFID tag worn by an attending party entering into close proximity to the monitored person indicating that the attending party has responded to an alert activated in response to the detected movement.
