minutes

• Chicago agenda & test readiness
  • As posted last meeting. We have generated test content and a validator
• Questions
  • Should datetime always include offset?
    • It should, but it's ok to send without. But the assumption is that a time without an offset is GMT.
  • What's a document id? It's not in NTDS.
    • NTDS currently identifies a record with "patient id." This should be the "setId" in CDA--it will stay consistent from version to version. VersionNumber should be a serial number. And document.id.extension can be whatever you want, as long as it uniquely identifies the document instance within the namespace of the document.id.root OID.
    • TBD: if we have a distinguishing Document.effectiveTime (last modified date/time), do we really need the "versionNumber"?
  • How do we represent null values?
    • Use the nullFlavor attribute. For Observation.value, you still must specify the type, but no other attributes; e.g.,
      • <value xsi:type="PQ" nullFlavor="NA" />
    • The two flavors we use will be HL7 null flavor "NA" (not applicable) for NTDS "1" (not applicable) and HL7 null flavor "UNK" (unknown) for NTDS "2" (not known/not recorded).
    • This guidance will be added to the guide.

Open Action Items

• Jay - identify correct value sets for FIPS/GNIS

Closed Action Items

• Jay - determine whether sections must be sent in order: technically no, but validators & voters may expect it, and no additional effort is involved
• Jay - confirm context control unnecessary: confirmed, but including it does not cause problems
• Jay - send LOINC & CDC URLs for codes (http://search.loinc.org/, phinvads.cdc.gov)
• Jay - send tracker URL (http://gforge.hl7.org/gf/project/trauma_cda_dstu/tracker/?action=TrackerItemBrowse&tracker_id=889)
• Jay - mark up and distribute ImageTrend's sample file
• Jay - send validator URL (http://ccda-scorecard.smartplatforms.org/static/ccdaScorecard/#/)
• AMS - republish the guide with LOINC values (and changes identified in log)
