For Procedure Occurrence: Use this date to determine the date the procedure occurred.
If a procedure lasts more than a day, then it should be recorded as a separate record for each day the procedure occurred, this logic is in lieu of the procedure_end_date, which will be added in a future version of the CDM. - For Note Nlp: The date of the note processing. - For Observation: The date of the Observation. Depending on what the Observation represents this could be the date of a lab test, the date of a survey, or the date a patient's family history was taken.
For some observations the ETL may need to make a choice as to which date to choose. - For Note: The date the note was recorded. - For Specimen: The date the specimen was collected. - For Measurement: Use this date to determine the date of the measurement.
If there are multiple dates in the source data associated with a record such as order_date, draw_date, and result_date, choose the one that is closest to the date the sample was drawn from the patient.
