Health Information Technology   HIE  

Health Information Exchange - Overview

Health Information Exchange (HIE) enables health care providers to transfer data through electronic networks among disparate health information systems.  Information available through an HIE typically includes laboratory results, radiology reports, discharge summaries, consultation notes, history and physical notes, operative notes, and secure clinical messaging and referrals.  Providers may access information through an HIE via an online portal, secure messaging, or through their electronic health record system or other system. The goal of HIE is to deliver electronically the right health information to the right place at the right time. 

The State Designated Health Information Exchange

In 2009, the Maryland Health Care Commission (MHCC) and the Health Services Cost Review Commission (HSCRC) designated the Chesapeake Regional Information System for our Patients (CRISP or State-Designated HIE) to build and maintain the technical infrastructure to support a statewide HIE.  The long-term goal of the State-Designated HIE is to build the fundamental foundation for interoperability to communicate health data among Maryland physicians, hospitals, and other health care organizations and providers.  The State-Designated HIE will also enable communities with regional HIEs to connect to other communities around the State and, in the future, with providers in other states.

Statewide HIE Evaluation Report

The MHCC compiled this report for Maryland under the State HIE Cooperative Agreement Program to meet the requirements in the program information notice issued by the Office of the National Coordinator (ONC) for Health Information Technology; the plan was approved by ONC. The report describes the approaches and strategies used by the State Designated HIE to facilitate and expand HIE in priority areas; identifies conditions influencing implementation of program strategies; assesses how HIE performance has progressed in key program priority areas; and assesses how key approaches and strategies implemented by the State Designated HIE contributed to progress, click here.

HIE Privacy and Security Regulations and HIE Registration

The MHCC was given the authority under Maryland law on May 19, 2011, to adopt regulations for the privacy and security of protected health information (PHI) obtained or released through an HIE. COMAR, Health Information Exchanges: Privacy and Security of Protected Health Information, effective March 17, 2014, aims to ensure the privacy and security of PHI accessed, used, or disclosed through an HIE; improve access to clinical records by providers; and support public health goals. Among other things, the regulation also requires HIEs operating in Maryland to register with MHCC. 

On May 15, 2018, Senate Bill 17, Health Information Exchanges – Definitions and Regulations, was signed into law, changing the definition of an HIE. Effective October 1, 2018, HIE means “an entity that provides or governs organizational and technical processes for the maintenance, transmittal, access, or disclosure of electronic health care information between or among health care providers or entities through an interoperable system.” In addition, an HIE does not include an entity composed of health care providers under common ownership; or, if the organization and technical processes it provides or governs are certain transactions, carriers, carriers’ business associates, or an administrator.
