The term Hash IDcan be somewhat ambiguous. It refers to both the APCD Unique ID (ME998) and also the combination of the APCD Unique ID (ME998) + the Member Gender (ME013). To better align with analytic terminology and and provide clear information, the new definitions are here: APCD_Unique_ID = refers to field ME998. Hash_ID = refers to field ME998. Study_ID = concatenated APCD_Unique_ID (ME998) and member gender (ME013).
The term, Study_ID, will replace Hash_ID going forward. |
