Unique random number id per patient that combines the D_IDs across admissions/encounters.

See Generate Person IDs for how Person_IDs are generated and maintained. A new line is generated in L_Person table, and the Person_ID is assigned to Centralized data.mdb.L_Log table.Person_ID .

For the most part, Person_ID is permanently stored and therefore remains the same for new encounters of that patient in L_Log table/L_Person table.

As of 2019-02-06, Person_ID doesn't show in any form in CFE.

Consistency of Person_ID over time

If a record in L Person table were ever deleted and recreated it would never receive the same Person_ID next time around. However, a new, re-generated Person ID would still link all records for that patient. See Generate Person IDs#Algorithm summary for details.

Implication for data we have provided

Main office discussed that the Person ID might change over time if a PHIN changes as per PHIN_field#Multiple_PHINs_or_PHIN_changes_over_time. Julie is aware of this and will include this in any considerations about ongoing data she provides.
