Delaware Health Information Network

About DHIN

Delaware Health Information Network (DHIN) was the first live, statewide health information exchange in the nation.

Launched in 2007, today it serves all of Delaware’s acute care hospitals and nearly 100% of the state’s medical providers. More than 14 million clinical results and reports are delivered through DHIN each year. There are over three million unique patients with results on DHIN, including patients from all 50 states. DHIN shares real-time clinical information to improve patient outcomes, eliminate the duplication of services and reduce the cost of healthcare.

In addition to its role as Delaware’s health information exchange, DHIN also powers the State’s Health Care Claims Database. The database collects healthcare claims, enrollment, and provider data from Medicare, Medicaid and the seven largest commercial health insurers in the State of Delaware, making it the single largest repository of claims data Delaware has ever had.


DHIN’s roots reach back to 1997 when the Delaware General Assembly enacted the organization as a public/private partnership. The objective was, and remains today, to advance the creation of a statewide health information network that addresses our state’s needs for timely, reliable and relevant health care information.


  • 2007: DHIN “went live” – meaning it became the first operational statewide health information exchange in the nation.
  • 2012: This “public instrumentality” of the State of Delaware became fully self-sustaining, funding its operations through revenue from its data services.
  • 2015, DHIN became the first public health information exchange to reduce participation fees for its data senders (and did so again in 2016 and 2019).


Members of DHIN have access to:

  • A searchable patient clinical history (including medications), available to authorized DHIN users on a “need-to-know” basis
  • A web-based portal for those without an electronic health record (EHR), including auto-print functionality for paper charting
  • A direct interface into the EHR with patient record-matching, for those providers with DHIN-certified EHRs

DHIN saves time, improves patient care and saves lives.

“The information on DHIN is so helpful to our practice. We have patients come into the office that can’t remember where they had lab/radiology work done. Utilizing the DHIN system, we log onto DHIN, type in the patient’s name and we can see where the patient had reports done. It really does help us from having to call around and track down that information.”
