IHE Patient Care Device Technical Framework Supplement – Alarm CommunicationManagement (ACM)______________________________________________________________________________3.8 IHE PCD-06 wctp-SubmitRequest – Call Back Phone Number2085The following ACM profile proprietary extensions to the wctp-SubmitRequest are used toconvey the HL7 Call Back Phone Number from the ACM AM to the ACM AC.2090The WCTP 1.3r1 interface specification that is the basis for ACM AM – AC communicationdoes not support the ability to pass other than a client request contact phone number inassociation with a message submit request. For this reason the ACM profile is required to extendthe WCTP 1.3r1 interface specification in a backward transparent manner in order to convey theHL7 Call Back Phone Number (OBR-17) from the ACM PCD-04 HL7 message received by theACM AM from the ACM AR for sending to the ACM AC.20952100In order for the WCTP server (the ACM AC actor) to signal its willingness to receive andpotentially support these IHE ACM profile WCM specific extensions to WCTP 1.3r1, per theextensions mechanism defined in section 3.6 Protocol Version of the WCTP 1.3r1 interfacespecification, the DTD response value shall be “IHEPCD-PCD06-V1R1” to indicate support forreception of the Call Back Phone Number extension to WCTP 1.3r1. This version shall presumeat a minimum WCTP version 1.3r1 capabilities, with primary emphasis on the ability of theWCTP server (ACM AC actor) to support paired MCR if sent in a wctp-SubmitRequest messagefrom the WCTP client (the ACM AM actor) to the WCTP server (the ACM AC actor).21052110On wctp-SubmitRequest messages the WCTP 1.3r1 interface specification supports a choice ofone of wctp-Alphanumeric (simple text with no MCR), wctp-TransparentData (binary encodeddata), or wctp-MCR (simple text accompanied with either unpaired or paired MCR). Since onlysmarter devices, associated with the newest WCTP implementations, are expected to make use ofthe additional WCM information in the PCD-06 transaction and so as to offload simple non-MCR message WCTP implementations from having to ignore the extensions, the wctp-MCRelement tree has been selected as the extension point for the WCM related additional XMLelements.2115In order to pass the Call Back Phone Number used for the ACM nurse call use case for telephonycall back to the patient in the room, or for the ACM laboratory results/observations use case fortelephony call back to the results provider/order filler for any required results/observation readback, the following additional WCTP XML element is defined specifically to pass the telephonydial back string from the ACM AM to the ACM AC by means able to be more deterministicallyreferenced than simply including the string in the message text sent to the endpointcommunication device operator.2120__________________________________________________________________________81Rev. 1.3– 2012-08-16Copyright © 2012: IHE International, Inc.
