What’s the Difference Between
eHealth Exchange, Carequality, and The Sequoia Project?
Interoperability Is a Multifaceted Challenge.
So Are The Sequoia Project’s Solutions

Defining the eHealth Exchange and Carequality
The Sequoia Project team is regularly asked, “What’s the difference between the eHealth Exchange and Carequality?” We want to answer the question clearly to assist with any lingering confusion. Both the eHealth Exchange and Carequality are independent of The Sequoia Project. They complement each other in our pursuit of seamless and accurate health data sharing nationwide.
Let’s start with the eHealth Exchange, The Sequoia Project’s first interoperability initiative.

Sequoia assumed stewardship of the nationwide health information network exchange (or NwHIN Exchange) from ONC in 2012. The eHealth Exchange is a public-private, health information network, and it happens to be the largest of its kind in the country. While an initiative incubated by The Sequoia Project, the network more than quadrupled in size to connect participants across all 50 states and support more than 120 million patients. Recognizing the maturity and sustainability of the network, the eHealth Exchange became independent of The Sequoia Project in 2018.
In addition to providing the ability to connect members to each other, the eHealth Exchange network does provide some shared services, including a rigorous testing program to ensure connectivity and interoperability.
Now that you understand that…

The eHealth Exchange
is a network…
IT’S MUCH EASIER TO
DIFFERENTIATE CAREQUALITY.

Carequality
is not a network.

The Sequoia Project partnered with health IT leaders in the public and private sectors to create the answer: Carequality.
The physician cannot join Carequality directly (remember, Carequality isn’t a network), but when their existing network adopts and implements the Carequality Interoperability Framework, the physician will be able to share healthcare data with other providers who connect through entirely different networks, without additional special effort.
Health data sharing opportunities are dramatically expanded to include additional providers, payers, and other care settings, and others as the Carequality community grows. This in turn helps patients receive better care, increases healthcare efficiency and decreases healthcare costs.
In response to the success of Carequality initiative, it was re-launched as an independent non-profit in 2018.

Carequality Overview Video:

The Sequoia Project is a non-profit, public-private collaborative dedicated to advancing implementation of secure, interoperable nationwide health data sharing.
We are not an association, which typically prioritizes benefits to its membership over benefits to the public, and we aren’t a think tank, because we are action-oriented thought leaders who implement interoperability in the real world.
We proactively address the multi-faceted and complex challenges of health IT interoperability, including testing for reliable health information exchange, ensuring content of the data exchanged is useful, improving patient identity management nationwide, and much more.
The challenges of healthcare IT interoperability are complex and multifaceted, and so The Sequoia Project incubates several initiatives that are managed and staffed independently. The eHealth Exchange and Carequality, now subisaries, are examples of our track record of implementing health data sharing solutions.
