Abstract

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 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.

Claims

1. A monitoring system comprising:

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; and

a processor adapted to;

1) receive data representing the sensed external parameter;

2) 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; and

3) generate a notification of the likelihood.

2. The system of claim 1 wherein the likelihood generated by the processor by executing the machine readable instructions is an overall likelihood which accounts for the sensed external parameter and also accounts for at least one ofa baseline likelihood that the occupant will attempt egress, andan occupant support related likelihood that the occupant will attempt egress, and

wherein neither the baseline likelihood nor the occupant support related likelihood is based on the data representing the sensed external parameter.

3. The system of claim 2 wherein the occupant support related likelihood depends on at least one of a siderail configuration, a support deck elevation, and a reading from a patient position monitoring system.

4. The system of claim 1 wherein the sensed external parameter is related to one or more of 1) an animate object, 2) an inanimate, spatially fixed object, 3) an inanimate, movable object and 4) an ambient condition.

5. The system of claim 1 wherein the sensing subsystem includes a suite of RFID components.

6. The system of claim 5 wherein the sensed external parameter is related to an object and the suite of RFID components includes an RFID reader associated with the occupant support or occupant and an RFID tag associated with the object.

7. The system of claim 6 wherein the object is a person.

8. The system of claim 6 wherein the object is a person, the tag reveals at least one attribute of the person and the received data includes the attribute.

9. The system of claim 8 wherein the attribute is one or more of:

a) a distinction between an authority figure and a non-authority figure;

b) an authoritativeness status of a person.

10. The system of claim 1 wherein the received data includes an attribute of the sensed external parameter.

11. The system of claim 1 wherein the external parameter is a parameter representing an object or a condition in the region of interest and wherein the region of interest does not include either the occupant support or the occupant.

12. The system of claim 11 wherein the object in the region of interest does not include objects which are inherent or commonplace components of a hospital bed.

13. The system of claim 11 wherein the object in the region of interest does not include objects supported on the bed and provided on an as-needed basis to serve the needs of selected occupants.

14. A monitoring system comprising:

a memory containing information about a region of interest relative to an occupant support; and

a processor adapted to

1) accept the information about the region of interest from the memory;

2) receive data representative of at least one external parameter not included in the information about the region of interest stored in the memory;

3) execute machine readable instructions thereby causing the monitoring system to evaluate, based on the accepted and received information, a likelihood that an occupant of the occupant support will attempt egress from the occupant support; and

4) generate a notification of the likelihood.

15. The monitoring system of claim 14 wherein the information in the memory about the region of interest is information about an inanimate and spatially fixed object in the region of interest.

16. The monitoring system of claim 15 wherein the information in the memory about the region of interest is information about at least one of the identity of the object and the spatial relationship between the object and the occupant support or the occupant.

17. The system of claim 14 wherein the memory is a read/write memory.

18. The system of claim 14 wherein the external parameter is related to one or more of 1) an animate object, 2) an inanimate, spatially fixed object, 3) an inanimate, movable object and 4) an ambient condition.

19. The system of claim 14 wherein the likelihood generated by the processor by executing the machine readable instructions is an overall likelihood which accounts for the accepted information about the region of interest from the memory and the received data representative of at least one external parameter, and also accounts for at least one ofa baseline likelihood that the occupant will attempt egress, andan occupant support related likelihood that the occupant will attempt egress, and

wherein neither the baseline likelihood nor the occupant support related likelihood is based on either or both of the accepted information about the region of interest from the memory and the received data representative of at least one external parameter.
