IHE Patient Care Device Technical Framework, Vol. 2: Transactions________________________________________________________________________Table 6 RCP Response Control Parameter Field Description and CommentaryFieldSeq(QueryID=Z99)NameComponentNameLEN DT Description1 Query Priority 1 ID I3 Response Modality 60 C RE3.2.6.1 Trigger eventsThe QSB^Z02^QSB_Q16 message is defined by the IHE PCD based on the rules definedin HL7 v2.5 Chapter 5.7 for Publish and Subscribe messages. The QSB^Z02^QSB_Q16is sent from a DOC to a DOF for the purpose of creating a new subscription or modifyingan existing subscription. Permission for a DOC to send the QSB^Z02^QSB_Q16 to aDOF is defined at implementation time.3.2.6.2 Message Semantics1020Refer to HL7 2.5 Chapter 5.4.4 for the general message semantics of the QSB messageand Chapter 5.7 for the details of Publish and Subscribe.The IHE PCD QSB^Z02^QSB_Q16 message defines the parameters which define thefilter to be applied to a stream of device observation messages. The current version of theIHE PCD TF provides facilities for selecting messages based on:• A list of one or more patients identified by a patient identifier• A list of one or more patient locations• A list of one or more device classes• A list of one of more specific device parameter classesThe IHE PCD QSB^Z02^QSB_Q16 also provides parameters which define the:• Date and time at which the subscription is to begin, the default is immediately.• Date and time at which the subscription is to end, the default is never.• The interval between periodic reports.The parameters of the QSB^Z02^QSB_Q16 are combined based on a logical AND todefine the overall query. For those parameters which define a list of one or more entriesthe elements of the list are combined based on a logical OR and satisfaction of anymember of the list satisfies the condition for the respective parameter.If the Action Code is set to A, the parameters are added to an existing subscription.If the Action Code is set to D, the parameters are deleted from an existing subscription.Rev. 1.1 TI: 2006-08-1523Copyright © 2005-2006: ACC, ACCE, HIMSS, and RSNA
IHE Patient Care Device Technical Framework, Vol. 2: Transactions________________________________________________________________________3.2.6.3 Expected ActionUpon receipt of a QSB^Z02^QSB_Q16 the DOF establishes a subscription based on theparameters defined and communicates those messages satisfying the subscriptionpredicate using the PCD-01 transaction to the subscriber.1020Appendix AISO/IEEE 11073 Mapping to HL7IEEE 11073 defines PCD semantics in terms of an information model and anomenclature. The information model is defined in ISO/IEEE 11073-10201 HealthInformatics – Point-of-care medical device communication – Part 10201 : DomainInformation Model. The nomenclature is defined in ISO/IEEE 11073-10101 HealthInformatics – Point -of-care medical device communication – Part 10101: Nomenclature.Familiarity with these standards is necessary for implementers of the Device ObservationReporter and Device Observation Filter actors.HL7 V2.5 Chapter 7 Observation Reporting defines the syntax and coding requirementsused for PCD data communications in the PCD TF. Familiarity with HL7 Chapter 7 isnecessary for implementers of the PCD TF transactions.One of the key contributions of the PCD TF is the definition of common semantics forPCD data communication in the enterprise environment. This is accomplished by theDevice Observation Reporter and Device Observation Filter actors through mapping ofthe IEEE 11073 semantics to equivalent elements of HL7.The purpose of this appendix is to describe the model which is used to map from IEEE11073 semantics to HL7.A.1 Mapping ISO/IEEE 11073 Domain Information Modelto HL7Figure 6 System Package Model represents the system level containment of the 11073DIM.Rev. 1.1 TI: 2006-08-1524Copyright © 2005-2006: ACC, ACCE, HIMSS, and RSNA
