Health Information Technology   Health information exchange  


Health information exchange (HIE) enables a broad spectrum of authorized users to securely share and access patient health information electronically. Enactment of the Health Information Technology for Economic and Clinical Health Act (HITECH) of 2009 expanded development of the critical infrastructure necessary for electronic information exchange. Today, HIEs range from regional, public entities (including State-Designated entities) to enterprise-wide (health systems) and vendor-mediated exchange (electronic health record systems with HIE functionality). HIEs support State and federal efforts to improve quality, safety, and efficiency in health care by making the right information available in the right place at the right time. 

Post-HITECH, standards and services exist to support electronic information exchange in health care; however, exchange is often limited between one care setting and another. In January 2018, the Office of the National Coordinator for Health Information Technology released the Trusted Exchange Framework and Common Agreement (TEFCA) draft, which builds upon the significant work done by the health care industry over the last decade. TEFCA aims to advance nationwide interoperability through a set of principles designed to facilitate trust among authorized participants, and complement emerging national frameworks that support exchange across multiple networks. A key goal is to enable providers, hospitals, and other stakeholders to exchange data across organizational boundaries. Other goals center on improving patient access to their data and encouraging population-level data exchange.

Information for Consumers

Consumers benefit from understanding the electronic exchange of their health information among treating providers.  The MHCC is helping to raise consumer awareness of electronic health information exchange (or HIE).  For more information, visit MHCC's HIE Consumer web page.

State-Designated HIE

Maryland law (2009) charged MHCC and the Health Services Cost Review Commission (HSCRC) with the designation of a statewide HIE. The Chesapeake Regional Information System for our Patients (CRISP) was competitively selected to build and maintain the technical infrastructure to support secure electronic information exchange statewide. State-Designation occurs every three years to ensure CRISP can continue meeting the founding principles for HIE in Maryland, as well as further advance the technical HIE infrastructure in alignment with evolving federal policy. CRISP provides a variety of tools and services to meet the needs of health care stakeholders, such as direct messaging, patient encounter notifications, data analytics and reporting, and the Prescription Drug Monitoring Program.

Quarterly Reports

CRISP reports quarterly to MHCC information on participating organizations and their utilization of HIE services. For more information, click here.

Law and Regulations

Maryland law (2011) requires MHCC to adopt regulations governing the privacy and security of protected health information (PHI) obtained or released through an HIE. COMAR 10.25.18, Health Information Exchanges: Privacy and Security of Protected Health Information (effective March 17, 2014) aims to ensure privacy and security of PHI accessed, used, or disclosed through an HIE; improve access to clinical records by treating providers; and support public health goals through permitted secondary use of data (e.g., research). The regulations increase privacy and security protections established by the Health Insurance Portability and Accountability Act of 1996 (HIPAA), as amended by the HITECH.


Existing law requires entities operating in Maryland that meet the definition of an HIE to register with MHCC annually. There are currently 12 HIEs registered with MHCC. For more information, including how to register or renew registration, click here.

HIE Policy Board

The MHCC develops recommendations for HIE in the State taking into consideration diverse perspectives shared by an HIE Policy Board, a stakeholder advisory group. For more information about the HIE Policy Board, click here.

Health Data Utility Roundtables

In July 2021, MHCC convened several national HIEs and state leaders to discuss challenges and opportunities related to advancing electronic health information exchange.  Outcomes of these discussions highlighted a need for HIEs under certain circumstances to function more broadly as a utility that supports providers, payors, and public health agencies.  A resulting series of national roundtable events (January – April 2022) with states and HIEs was held in collaboration with Civitas Networks for Health and the Association for Health IT State Leaders.  The roundtables covered opportunities, challenges, and solutions to establishing a statewide health data utility (HDU), which is an advanced model of health information exchange, providing services (regionally, statewide, or across state lines) for clinical and public health purposes.[1]  Roundtable participants included HIEs, state agencies, regional health improvement collaboratives, and other stakeholders involved in public-private health data partnerships.
