To identify cases with auto-immune rheumatologic phenotye (for NT198) we request information about auto-antibody (whether it was tested and what the restults were) and drug information (whether it was prescribed) for each patients that is enrolled in eMERGE. We are requesting every mention of any of the expanded generic drugs.
The data dictionaries (located under the "data dictionary" tab) contain the generic names of the variables. As many systems use different names we anticipated on this by providing a wide range of possible names (including RxCui and RxNorms) for each drug and antibodies in the additional .xlxs files (under the "Files" section).
Please don't hesitate to contact me if there is any unclarity about the variables.
