Also HIE, state HIE, regional HIE
“HIE” is used two ways and the difference matters when an agency is deciding how to get records. As an activity, health information exchange is any electronic transfer of clinical data between organizations: a query across the networks, a Direct secure message, an admission notification. As an organization, an HIE is a regional or statewide body that connects the hospitals and practices in its area, aggregates their data, and offers its members a shared record, event notifications and a portal.
The organizations came first. Most states stood one up with federal money after 2009, and the survivors run on member fees and state contracts. Georgia’s is GaHIN; Indiana has IHIE; many states have one and some have several. Their value for outside records is specific:
- They hold the small practices. A rural clinic or a solo specialist that is on no national network is often connected to the state HIE, because the state or its Medicaid program arranged it.
- They are often on the national networks. Many state HIEs are Carequality implementers or TEFCA participants, so a network query reaches their members’ records through them without a separate membership.
- They send notifications. Admission, discharge and transfer alerts, which tell a home health or PACE organization that a patient is in the hospital before the family calls, generally come from the state HIE rather than the national networks.
For an agency the practical question is whether a given source is reachable, and through what. The national frameworks (Carequality, CommonWell, TEFCA) reach the large systems and the vendors’ customers; the state HIE reaches the rest of its state; and a query service worth having asks all of them.
