Abstract

A nurse call system includes an integrated locating system. The system includes room-level IR/RFID tracking features. Transition zones incorporate hysteresis to identify transition lines for entering a specific room or location. Capabilities of located persons or assets may be associated with patient treatment plans and/or care alerts based on proximity. Confidence levels may be determined based on information received from multiple tracking systems.

Claims

1. A healthcare communication system comprising

a plurality of RFID transmitters carried by persons or assets in a healthcare facility, each transmitter periodically transmitting a transmitter signal unique to that transmitter,

a plurality of receivers, each corresponding to a location in the healthcare facility, each configured to receive the transmitter signals and output a receiver signal, and

a computer configured to substantially simultaneously monitor the location and tracking of persons or assets carrying the transmitters and control patient-nurse communications by defining transition zones within the healthcare facility and determining confidence levels associated with located persons and assets, wherein the confidence levels are determined only if the persons or assets are located in a transition zone.

2. The system of claim 1, wherein the computer is configured to operate a nurse call system.

3. The system of claim 2, comprising a first I/O board coupled to the computer, wherein the first I/O board includes a first locating and tracking subsystem configured to locate persons or assets, incorporated therein.

4. The system of claim 3, wherein the plurality of receivers includes a first receiver incorporated into the first I/O board.

5. The system of claim 4, wherein the first receiver is an RF receiver.

6. The system of claim 3, comprising a second I/O board spaced from the first I/O board, wherein the second I/O board includes a second locating and tracking subsystem configured to locate persons or assets, incorporated therein.

7. The system of claim 6, wherein the plurality of receivers includes a first receiver incorporated into the first I/O board and a second receiver incorporated into the second I/O board.

8. The system of claim 7, wherein the first receiver is an RF receiver and the second receiver is an IR receiver.

9. A healthcare communication system comprising a patient-nurse communication subsystem and a locating and tracking subsystem coupled to the patient-nurse communication system, the locating and tracking subsystem being configured to monitor transition zones and use hysteresis to determine the location of a person or asset being monitored by the locating and tracking subsystem.

10. The system of claim 9, wherein the locating and tracking subsystem includes a plurality of receivers, each receiver is configured to monitor a defined zone, and at least two receivers monitor each transition zone.

11. The system of claim 10, wherein each transition zone includes a physical area located in between two zones.

12. The system of claim 10, wherein at least one of the transition zones includes an area located adjacent an entryway to a room of a healthcare facility.

13. The system of claim 10, wherein at least one transition zone includes a portion of a common area located adjacent a door to a patient'"'"'s room.

14. The system of claim 13, wherein the at least one transition zone includes a portion of the patient'"'"'s room located adjacent to the door.

15. A healthcare communication system comprising a combined patient-nurse communication and locating and tracking system, the combined system including a decision engine configured to associate one or more capabilities of a located person or asset with one or more care recommendations and issue an alert regarding the one or more care recommendations.

16. The system of claim 15, wherein the decision engine issues an alert if a located person'"'"'s location has changed.

17. The system of claim 16, wherein the decision engine is configured to send an alert to a caregiver assigned to the located person if the located person is located in a room assigned to the located person.

18. The system of claim 17, wherein the alert includes a reminder to activate equipment located in the person'"'"'s room.

19. A healthcare communication system comprising a combined patient-nurse communication and locating and tracking system, the combined system including a program executable to determine a confidence level associated with a located person or asset based on information received from a plurality of locating and tracking mechanisms including an IR tracking mechanism and an RFID tracking mechanism.

20. The system of claim 19, wherein the system determines the confidence level by evaluating data from a plurality of locating and tracking mechanisms including an IR locating and tracking mechanism and an RF locating and tracking mechanism.

21. The system of claim 19, wherein the system is configured to monitor a plurality of transition zones, each transition zone includes an area located between zones monitored by different receivers, and the system determines the confidence level of the located person or asset if the located person or asset is in a transition zone.
