Problem statement

CVS has requested some Sender transforms be created for their HL7 connection before they can meet ReportStream's NIST validation requirements.

What you need to know

• From CVS:
  • OBX (4-6) from below are metadata fields that we are actively trying to suppress in Epic as they don’t need to be shared externally. That changes may take several months, but you will notice they will be missing LOINC codes. Can you set a rule on your end to ignore OBX segments with missing LOINC codes? Or to your point, you can look for lot#, expiration, internal controls, and test brand.
  • We practically cannot send snomed codes with our current build. Can reportstream assist with converting our results and spec type to snomed? I can share our mappings today for the DOH file extracts as we hardcode these in:
    Positive = 260373001
    Negative = 260415000
    Invalid = 455371000124106
    Specimen type OTHER = 445297001
• Because they're only sending a String for OBX-5, the value under OBX-2 is ST. Once we transform the message to have a SNOMED code in OBX-5 the data type of the OBX segment will need to be CWE. An additional transform is needed for that.

Acceptance criteria

• CVS changes made per above requirements
• Changes tested with CVS team members to ensure transforms meet expectations
