Our challenges with consumer-directed HIE are directly related to individuals not having a portable, digital identity credential they can use across various different data holders. Over the last year, the CARIN Alliance and FAST launched a wide-scale collaboration – working with HHS, CMS, ONC, and more than 25 private sector partners, including health systems, payers, third-party applications, and trust framework organizations – to test the largest and most comprehensive digital identity open framework. We will share our lessons learned, best practices, and next steps for how we can have a fully interoperable, voluntary, federated digital identity ecosystem in health care as we move to a modern identity and access management ecosystem that supports OpenID Connect.
