Drug Administration records in Drug_Exposure table


For a patient, while administering a particular drug, there are multiple actions (like drug given, on hold, rate changed, stopped etc) taken at various times. How do we capture all these actions in Drug_Exposure ?


The OMOP CDM is only interested in events that happen to the patient, so do not expect of find a way to record that the order is on hold, or cancelled. There are start and end dates and times, so you can indicate stopped. Others are going to have to help you with how to handle rate changed.

As Don said, the CDM only contains clinical event records for events which occurred. So, if a patient missed or refused a dose of medication, then you don’t create a record in the CDM. When the rate changes, you end the first record and start the 2nd record with then new quantity of medication a person receives.
