Summary

The race is captured as a singular data element, however its possible that more than one race exists on an incoming document (as is the case in FHIR). We need to allow for multiple race values in a submission and update our FHIR parsing logic to capture all of them, not just the last one.

Impact

Losing race information in our records can negatively impact patient to patient comparisons.

Expected behavior

• Allow users to submit more than one race value in our PIIRecord
• Yield all the possible RACE values in the feature_iter
• Capture all the race values submitted in the FHIR document, not just the last one
