a plurality of transient credentials, wherein each transient credential of the plurality of transient credentials comprises an optical sensor configured to detect the optical indicia on the optical identification tag associated with each hygiene station, and wherein the transient credential is configured to identify the characteristic of the hygiene station indicated by the optical indicia detected by the optical sensor;

an optional controller, wherein the plurality of transient credentials are operably connected to the controller through a communication link that comprises communication devices in the plurality of transient credentials;

wherein the system is configured to associate a cleaning event at a selected hygiene station with a selected transient credential based on detection of the optical indicia of the optical identification tag associated with the selected hygiene station by the optical sensor of the selected transient credential.

2. A system according to claim 1, wherein the system further comprises an optical identification tag associated with a patient in the health care facility, wherein the patient-associated optical identification tag is located on or near the patient and comprises optical indicia indicative of a characteristic of the patient;

wherein the optical sensor of each transient credential of the plurality of transient credentials is configured to detect the optical indicia on the optical identification tag associated with the patient, and wherein the transient credential is configured to identify the characteristic of the patient indicated by the optical indicia detected by the optical sensor;

wherein the system is configured to determine if the cleaning event at the selected hygiene station is a proper cleaning event for the patient based on the characteristic of the patient indicated by the optical indicia on the optical identification tag associated with the patient.

3. A system according to claim 1, wherein the system further comprises an optical identification tag associated with a health care bundle, wherein the bundle-associated optical identification tag is located on the health care bundle and comprises optical indicia indicative a characteristic of the health care bundle;

wherein the optical sensor of each transient credential of the plurality of transient credentials is configured to detect the optical indicia on the optical identification tag associated with the health care bundle, and wherein the transient credential is configured to identify the characteristic of the health care bundle indicated by the optical indicia detected by the optical sensor;

wherein the system is configured to determine if the cleaning event at the selected hygiene station is a proper cleaning event for the health care bundle based on the characteristic of the health care bundle indicated by the optical indicia on the optical identification tag associated with the health care bundle.

4. A system according to claim 1, wherein the characteristic identified by the optical indicia on the optical identification tag associated with a hygiene station comprises the location of the hygiene station.

5. A system according to claim 1, wherein the characteristic identified by the optical indicia on the optical identification tag associated with a hygiene station comprises the type of the hygiene station.

6. A system according to claim 1, wherein the characteristic identified by the indicia on the optical identification tag associated with a hygiene station comprises data identifying a patient associated with the hygiene station.

7. A system according to claim 1, wherein each of the hygiene stations comprises two optical identification tags associated therewith, wherein each optical identification tag of the two optical identification tags comprises different optical indicia identifying a different characteristic of the hygiene station associated with the two optical identification tags.

8. A system according to claim 1, wherein the optical sensor comprises a camera.

9. A system according to claim 1, wherein the transient credential comprises a light source emitting light of a selected wavelength, and wherein the optical indicia selectively reflects or absorbs the light emitted by the light source.

10. A system according to claim 1, wherein the optical sensor and/or the optical indicia are configured to provide a distance determination indicative of the distance between the optical sensor and the optical indicia.

11. A system according to claim 1, wherein the controller comprises a patient zone controller, and wherein the system comprises data associating the patient zone controller with only one selected patient, and further wherein the patient zone controller is configured to define a patient zone proximate the selected patient.

12. A system according to claim 11, wherein the patient zone controller is configured to detect entry and/or exit of a transient credential of the plurality of transient credentials relative to the patient zone.

13. A method of monitoring hygiene protocol compliance in a health care facility, the method comprising:

associating a plurality of optical identification tags with a plurality of hygiene stations, wherein at least one optical identification tag is associated with each hygiene station, wherein the at least one optical identification tag is located on or near the associated hygiene station and comprises optical indicia indicative of a characteristic of the associated hygiene station; and

monitoring hygiene protocol compliance associated with a selected transient credential by;

identifying a characteristic of a selected hygiene station by detecting optical indicia on an optical identification tag associated with a selected hygiene station using an optical sensor of the selected transient credential;

associating a cleaning event at the selected hygiene station with the selected transient credential based on detection of the optical indicia of the optical identification tag associated with the selected hygiene station by the optical sensor of the selected transient credential.

14. A method according to claim 13, the method further comprising:

associating an optical identification tag with a selected patient, wherein the optical identification tag is located on or near the selected patient and comprises optical indicia indicative of a characteristic of the selected patient;

wherein monitoring the hygiene protocol compliance associated with the selected transient credential comprises;

identifying a characteristic of the selected patient by detecting optical indicia on the optical identification tag associated with the selected patient using an optical sensor of the selected transient credential; and

determining if the cleaning event at the selected hygiene station is a proper cleaning event for the selected patient based on the characteristic of the selected patient indicated by the optical indicia on the optical identification tag associated with the selected patient.

15. A method according to claim 13, the method further comprising:

associating a plurality of optical identification tags with a plurality of health care bundles, wherein at least one optical identification tag is associated with each health care bundle, wherein the at least one optical identification tag is located on or near the associated health care bundle and comprises optical indicia indicative of a characteristic of the associated health care bundle;

wherein monitoring the hygiene protocol compliance associated with the selected transient credential comprises;

identifying a characteristic of a selected health care bundle by detecting optical indicia on an optical identification tag associated with the selected health care bundle using an optical sensor of the selected transient credential; and

determining if the cleaning event at the selected hygiene station is a proper cleaning event for the selected health care bundle based on the characteristic of the selected health care bundle indicated by the optical indicia on the optical identification tag associated with the selected health care bundle.
