ONC offers HIE guidance

Seeks to "maximize the long-term value of services offered through health information exchange."

3. Provider directory solutions. These electronic white pages enable one provider to look up contact information for another provider. In the future, provider directories will have uses for health insurance exchanges and state licensing boards and may help HIEs attain sustainability.

4. Master data management. Master data management is how two pieces of electronic health information are appropriately merged or kept separate, which is difficult when there are varying levels of data quality on patient identities. Tools can help HIEs accurately capture and coordinate a patient’s identity and can be used for more advanced data analytics associated with new payment models or patient-centered medical homes.

5. Consumer engagement and consumer-mediated exchange. The research explains considerations in identity proofing, identity authentication and access, and several case studies, including from UnitedHealth Group, Aetna and Microsoft HealthVault.
