I have some doubts regarding the use of ATHENA. Is there anyone with some availability to help me?
Specifically, I am looking at the exercises of “Chapter 5 - Standardized Vocabularies” of the OHDSI book. The first (5.1) is very easy-peasy, but the second (5.2) is not (for me)… I keep getting different possible answers and I don´t understand why the suggested answers do not include all the possibilities.
I tried these strategies among others:
- Searching for “Gastrointestinal hemorrhage” as keyword and filtering “ICD10CM” or “ICD9CM” in Vocabulary;
- Searching for “Gastrointestinal hemorrhage” as keyword and filtering Standard concept = “Standard”; selecting Concept_ID=192671 and looking at the Term connections…
I’m sorry to post this naive question, but I having a hard time trying to figure this out by myself.
