discuss how to handle measurement_detail string and concept id use

[markdanese]

Should we use concept ids for results? Should they be used only for string results (i.e., string is the source value that goes with concept id)?

[markdanese]

If a data source uses LOINC, it is likely that the data will have a LOINC code for the "question" and the "answer" (result). In that case, we would need to use a concept id for both. Hence, we need "result_as_concept_id". So, there are 3 ways we can report a result (numeric value, string, and concept id). We should only have one of the 3 completed on each row. Strings should not be interpreted as a description field for the concept id. If we want to report a source value for the concept id, we can do that. It would give us a way to use a code for the result and also include a text string.

leaving open until we decide whether to include a "result as concept id source value" field.
