FHIR Tracker Items

TR#12802 -change name to singular to meet QA guidelines

  • AdditionalInstructions
    • Feb 9, 2017 - After brief discussion. Suggestion was to reach out to MnM to get an exception for changing the name from plural to singular. No vote today, to be discussed on Monday, Feb 13, 2017.

TR#12789 - Derived From on MedicationStatement - cardinality and constraint on type of reference

  • Derived From
    • Feb 9, 2017 - Michelle Miller stated that currently their FHIR implementation has a cardinality of 0..1, and they only support deriving Medication Statement from Medication orders. However in the Cerner system they also derive Medication Statements from claims (this is not implemented in FHIR). There was not a consensus that the cardinality could be constrained to 0..1. There were several examples proposed that would require cardinality 0..5 to 0..1. Action Item: John H to review list of FHIR resources to come up with a candidate list of resources that the Medication Statement can be derived from. No vote today, to be discussed on Monday, Feb 13, 2017.

TR#12758 - Consider whether batch/lot should be on product or package

  • Batch/Lot
    • Feb 9, 2017 - Discussion centered around to right fit for batch/lot. One suggestion was to move it under Package, and change cardinality of Package to 0..*. Action Item: Scott to investigate lot number and batch information and bring that information to next Monday's call.
