Notes/Thoughts:

  • IHI Implementation: There appear to be 3 “types” of the IHI (verified, unverified, provisional) and 5 “status indicators” (active, deceased, retired, expired, resolved) for the IHI. The “types” are transitional indicators for the IHI and are stored with the PAS (Patient Admin System). If the IHI “moves” from system to system, or Provider to Provider then there is a real risk that the “type” may not transition across due to timing.

  • Multiple Linkage IDs: States seem to have several layers of Ids used for linkage: E.g. Hospital, LHD, and state Id. For example, NSW Health use MRN at hospital level, AUID at LHD level, and EUID at state level. The national IHI could solve the problem of multiple Ids. Poor adoption and implementation of IHI is prevalent across the entire health system.
