One embodiment of a monitoring system includes a sensing subsystem adapted to sense an external parameter within a region of interest relative to an occupant support or an occupant of the occupant support. The monitoring system also includes a processor. The processor is adapted to adapted to receive data representing the sensed external parameter and to execute machine readable instructions thereby causing the monitoring system to evaluate, based on the received data, a likelihood that the occupant will attempt an egress from the occupant support. The processor is also adapted to generate a notification of the likelihood of attempted egress.
