Fill in mapping for OML/ORM

[brick-green]

Backlog Task

Following the OML/ORM mapping work completed by RS there remains a number of fields that unmapped.

• PID-2 - Missing because PID-2 is "Backwards Compatible" field in 2.5.1

• PID-12 - Missing because PID-12 is "Backwards Compatible" field in 2.5.1

• PID.19 and PID.20 - are deprecated in the HL7v2.7 and NIST HL7v2.5.1 specs. Further, the HAPI v2.7 model has set both # fields to NULLDT.

• ORC-7 - Missing because ORC-7 is "Backwards Compatible" field in 2.5.1

• OBR-27- Missing because OBR-27 is "Backwards Compatible" field in 2.5.1

• SPM-35 - Missing because SPM-35 does not exist in 2.5.1

Precondition

• We have recent sample order messages from Ochsner - attached below in the comments as "input.txt" and "output.txt"

Completion Criteria

• Above fields can be mapped into FHIR and back out to HL7 for OML
• Above fields can be mapped into FHIR and back out to HL7 for OML

Tasks

• Cross reference with Orders Gap Analysis, to ensure all the fields listed above are needed. ( see https://docs.google.com/spreadsheets/d/1irLQZ-Kr3Btud6yBnTw9J3OXCdrFuE4C/edit?gid=2047071728#gid=2047071728 and LA Gap Analysis - Test Orders #1091) - @tjohnson7021

  • NONE of the above fields are required by the LA PHL when reviewing the spreadsheet above.

• Validate if any of the fields above are already mapped.

• Create a document for tracking deviations of standard field mappings that ReportStream supports

• Document the level of effort in supporting a new, partner-specific field mappings

Other Notes

[JohnNKing]

ORC-7 not available in HL7 v2.7. May well be an issue with the other fields.

Need to check latest OML mapping in RS to confirm fields are missing

It looks like I may also need to add PID-12 to the list above (based on recent sample messages for LA)

Thanks @basiliskus ! That matches what I'm seeing. I'll pull this back into the Refinement column for tomorrow -- specifically to ask the team about adding PID-12 to this scope. For the Feeding Type OBX (67704-7), I'll create a new story. It seems to be related to fields that repeat.
