ORU^R43
ORU – Unsolicited Patient-Device Association Observation
The R43 trigger event is used for observation reports that indicate the association of one patient to one or more health care devices. This includes both patient-device association as well as disassociation when a device is removed from active use with a patient. Other messages may be utilized for this purpose (e.g., ADT); however, this message was chosen given the general use of ORU-style messages to communicate device data, including unique device identifiers (e.g., PRT-10 and UDI components), and the possible need to include additional device data such as hardware / software configuration. The R43 trigger provides indication of the specialized usage of this message. Note that OBX-3 Observation Identifier, PRT-4 Participation, and OBX-11 Observation Result Status represent the purpose of the association of the device and the status of that association as further defined through the appropriate implementation guides and/or profiles.
