What to do with NULL Death dates in OMOP?

Hi @MPhilofsky, I was thinking the same thing, but wasn’t sure b/c the patient could be past a a year or more later in the case of Tx patients.

@Christian_Reich the future date is something you mentioned before, but I agree w/ @MPhilofsky, I would prefer a NULL date over a future date (at least for v5.x). I don’t envy your task to keep the model and conventions slim, @Christian_Reich; it’s not an easy task. I do see that the future date idea works for both cdm versions, so I could be convinced to use it until we can do a death indicator somehow.
