Capturing time of day information for drugs

I have drug information that includes time of day information for example
1/2 10 mg tab AM, 1/4 tab afternoon, 1/2 tab QHS

I think I’d like to store as three records (separate rows).

They will each have a different dose, and the same start and end date, but how do I capture time of day?

Hello, Kieran

Use drug_exposure_start_datetime and drug_exposure_end_datetime fields.

You may read brief history of these fields here

However, OHDSI analytics tools have a resolution of 1 day, but you will be able to use datetime in your custom analysis if needed.
