Friends:
I think you are mixing up two issues: The interaction of the patient with the healthcare system (Visits) and the way data get captured (Types). For interactions that don’t involve patients coming to an office, like phone or email contact, you have the Visit concept Telehealth. How the data get captured (EHR, CRF, registry) is recorded through a Type concept (which are in the process of being revamped as we speak, the release is imminent). Documentation and abstraction are data capture activities carried out by some institution, the patient has nothing to do with it.
Let us know if you need more detailed Visit or Type concepts (after the release) and we add them in.
