I'm building a medication trial in OpenClinica 3.3. I want to register concurrent medication at each of the study visits. Currently, I have a repeating group to do that. I would like that in each subsequent visit, the repeating group is prepopulated with data from the previous time this CRF was completed so the physician can change them if needed and otherwise just save them.
I've done some research and found this thread from 2010
, which pointed to this excellent guide by trial data solutions
. Unfortunately, this deals with static data to prepopulate a repeating groep. I also understand how I can use 1 item in 1 CRF in a specific event to prepopulate using a InsertAction, but I'm not sure how I can select 'this specific item from this specific CRF from the previous event where this item was answered'.
