IHE Patient Care Device Technical Framework

102030IHE Patient Care Device Technical Framework, Vol. 2: Transactions________________________________________________________________________identifier (e.g., serial number) should be recorded in ‘universal ID’ component,with the Device or manufacturer name in ‘universal ID type’ component.Should be sent at the highest level of device related OBX possible: i.e. MDS, thenVMD, and then Channel. Inheritance should be assumed; i.e. for multivaluedresults from the same Device, this field is required only in the first OBX segment.For metric related data this field is not required – unless no device hierarchy, andtherefore related OBXs, is being declared; in which case the device ID should beprovided here if available. Inheritance should be assumed; i.e. for multivaluedresults from the same Device, this field is required only in the first OBX segmentOBX-19 Date/Time of the Analysis (TS), conditional may be empty:Conditional Predicate : May be used if duplicate of OBX-14For the PCD TF use OBX-14 preferentially if device time is relevant. Information inOBX-14 may be duplicated here if local needs dictate.OBX-20 Observation Site (CWE), required may be empty:Components: ^ ^ ^ ^ ^ ^ ^ ^ For the PCD TF this field, which has been defined for HL7 V2.6, is required andhas been added to the OBX segment. Since V2.6 has not been through a finalballot there is a risk that changes could occur due to the balloting. The PCDbelieves that this is preferable to specification of a Z segment. Comment isinvited.Definition: This field typically contains the body site(s) where the measurement beingreported was obtained. This field should not be used for a specimen source orspecimen collection site.This information is of particular importance if the clinical meaning of a value ismodified either directly by the site (for example, is the temperature central orperipheral?) or if the site of one measurement impacts the value of anothermeasurement (for example, is the finger SpO2 probe on the same arm as the NIBPcuff?). In most cases these observations are performed directly upon the patient anddo not involve a specimen.Any nationally recognized coding system might be used for this field includingSNOMED or MDC; alternatively the HL7 Table 0163 may be used. Veterinarymedicine may choose the tables supported for the components of this field as decidedby their industry.Rev. 1.1 TI: 2006-08-1554Copyright © 2005-2006: ACC, ACCE, HIMSS, and RSNA
