Health information exchanges (HIEs) come in various forms - regional, state-designated, EHR-driven, nationwide, and specialized - all aiming to facilitate secure electronic sharing of patient data to improve care coordination and outcomes.
Health Information Exchange (HIE) refers to the electronic movement of health-related information among organizations according to agreed-upon standards, protocols, and policies. The goal of HIEs is to facilitate access to and retrieval of clinical data to provide safer, more timely, efficient, and effective patient-centered care.
At the most fundamental level, an HIE enables the secure exchange of medical records and other health data between healthcare providers, hospitals, labs, pharmacies, and other entities involved in a patient's care. This allows a physician to access a comprehensive view of a patient's medical history, test results, medications, allergies, and more - even if that information is housed in different healthcare systems.
There are several different forms that HIEs can take:
Regional HIEs connect healthcare providers within a specific geographic area, such as a city, county, or state. These regional networks allow for the exchange of patient information among hospitals, clinics, labs, and other providers in that local region. Regional HIEs are often run by non-profit organizations or public-private partnerships.
Many states have designated a single statewide HIE that serves as the central hub for data exchange across the state. These state-designated HIEs are often operated by a state government agency or a non-profit organization tasked with overseeing health IT infrastructure. They provide the technical and governance framework to enable data sharing between providers throughout the state.
Some large healthcare systems or EHR vendors have built their own internal HIEs that allow their affiliated providers to share data. These EHR-driven HIEs leverage the existing EHR infrastructure and patient relationships to enable data exchange, often only within that specific healthcare network or EHR ecosystem.
Efforts are underway to create nationwide HIE networks that can facilitate data exchange across state and regional boundaries. These include initiatives like the CommonWell Health Alliance and Carequality, which are building interoperability frameworks to connect disparate HIE networks. The goal is to enable a patient's health information to follow them, regardless of where they receive care.
There are also HIEs that focus on specific use cases or populations, such as behavioral health, public health reporting, or sharing data for research purposes. These specialized HIEs bring together providers and organizations with common needs around data exchange, going beyond just general clinical information.
The various forms of HIEs aim to improve care coordination, reduce redundant testing, and ensure providers have access to a more complete view of a patient's medical history. This is particularly important as healthcare continues to shift towards value-based care models that emphasize quality, outcomes, and cost-effectiveness.
While HIE adoption and usage has grown steadily over the past decade, challenges remain around data standardization, privacy/security concerns, and provider engagement. Nonetheless, robust HIE capabilities will be critical for delivering high-quality, coordinated care in the modern healthcare landscape.

The primary purpose of a Health Information Exchange (HIE) is to facilitate the secure and efficient exchange of health-related data between healthcare providers, hospitals, laboratories, pharmacies, and other entities involved in a patient's care. This allows for a more comprehensive view of a patient's medical history, test results, medications, and other critical information - even if that data is housed in different systems. The goal is to improve care coordination, reduce redundant testing, and ultimately deliver better health outcomes.
Regional HIEs connect healthcare providers within a specific geographic area, such as a city, county, or state. These regional networks allow for data exchange among the local hospitals, clinics, labs, and other providers in that defined region.
In contrast, state-designated HIEs serve as the centralized hub for data exchange across an entire state. They provide the technical and governance framework to enable data sharing between providers throughout the state, often operated by a state government agency or non-profit organization.
While regional HIEs focus on local connectivity, state-designated HIEs aim to facilitate broader statewide interoperability.
Despite the clear benefits of HIEs, there are still some challenges that have hindered widespread adoption and usage:
Overcoming these types of technical, regulatory, and cultural barriers remains an ongoing effort as the healthcare industry continues to evolve towards more coordinated, value-based models of care.
Nationwide HIE initiatives, such as CommonWell and Carequality, aim to build interoperability frameworks that can connect disparate regional and state-level HIE networks. The goal is to enable the secure exchange of patient information across state boundaries, so that a person's health data can "follow" them regardless of where they receive care.
While regional and state-level HIEs focus on connectivity within a defined geographic area, these nationwide initiatives are working to achieve true interoperability at a national scale. This requires aligning on common data standards, policies, and technical specifications that allow for seamless data exchange.
