Questions about book exercises ch. 4 and 5

@JDufhcc thanks for noticing these issues

Type concepts recently undergone a huge refactoring,
In short: now we don’t have separate vocabularies for each domain, but the one for all Type concepts for different domains. So the old concepts got deprecated and you need to use the new ones.
@Christian_Reich I don’t find any corresponding concept for “period while enrolled in insurance”, can we add something similar?
For excrercise 4.3 you may use EHR prescription
Please note, concepts you suggested don’t work as they have to have specific domain = ‘Type Concept’.

MedDRA is linence restricted, so the concepts can’t be seen without having a licence.

I’ll create an issue here
