IHE Patient Care Device Technical Framework

1020IHE Patient Care Device Technical Framework, Vol. 2: Transactions________________________________________________________________________provide the device measurement range capability – NOT the metric value ‘alarm’ranges which shall be in the appropriate observed value metric OBX. For metricrelated segments although not strictly a reference range in the sense of the examplesgiven in HL7 this should be used to provide the value ‘alarm’ ranges set with respectto the observed value metric in this OBX.OBX-8 Abnormal Flags (IS), required but may be empty:For the PCD TF the preferred format is an MDC value, secondly a LOINC value.This represents a PCD TF recommendation for HL7 User Table 0078. For devicerelated segments use for device status alerts – not the value “alert” flags which shouldbe in the appropriate observed metric value OBX. For Metric related segments use forobserved value metric status alerts with respect to the observed value metric in thisOBX.OBX-11 Observation Result Status (ID), required:This field should be filled according to HL7 Table 0085 described in Chapter 7 ofHL7. For the IHE PCD TF, the possible values for this field for this profile are shownin Error! Reference source not found.. The value of X is used for device relatedsegments where OBX-7 is not used to express the device measurement rangecapability.Table 22 HL7 Table 0085 selected valuesValue Description CommentC Record coming over is a correction andthus replaces a final resultD Deletes the OBX recordF Final results; Can only be changed witha corrected result.P Preliminary resultsR Results entered -- not verifiedS Partial resultsU Results status change to final withoutretransmitting results already sent as‘preliminary.’W Post original as wrong, e.g., transmittedfor wrong patientX Results cannot be obtained for thisobservationOBX-14 Date/Time of the Observation (TS), required but may be empty:For the PCD TF the value is the same as OBX19, but should be used in preference toOBX19 if time is relevant.
