National Association of Health Data Organizations

Improving Healthcare Data Collection and Use Since 1986

NAHDO is the National Association of Health Data Organizations: the only association for the organizations that collect, analyze, and release healthcare data, including statewide hospital discharge and all-payer claims databases. Since 1986, we have given them a place to learn from each other, alongside federal agencies, researchers, vendors, and others in the health data space. We help them agree on standards and make the case for using their data.

What NAHDO Does

Four ways NAHDO helps the people who work with healthcare data.

NAHDO's Value to Members

Technical Assistance

We answer members' questions about collecting, analyzing, and releasing healthcare data, or connect them with a peer who has solved the same problem.

Networking and Communication

We bring members together at the Annual Conference, NAHDO Connect, and webinars, and keep them current through NAHDO News.

Promoting Standardization

We work with national standards groups to make healthcare data uniform and comparable across states.

Federal Awareness

We are opening a two-way channel between members and federal policy makers and agencies, so members' data needs are heard and federal news reaches them.

Programs and Initiatives

Programs that NAHDO manages for the benefit of our members.
