The Mass HIway

The goal of the Mass HIway is to support the electronic exchange of patient information across the healthcare community to achieve the best possible care coordination for Massachusetts residents. This includes enabling care providers in improving their processes of sharing, reconciling, and analyzing Protected Health Information (PHI) to facilitate better management of the quality and cost of care.

For this purpose, the Mass HIway offers a range of services and resources to facilitate the use of Health Information Exchange (HIE) by care providers across the Commonwealth of Massachusetts. The HIE efforts cover Direct Messaging, Query HIE, Event Notification Services (ENS), Public Health Reporting, and methods to enhance the interoperability of healthcare systems and workflows by means of HIE utilization.

The HIway is operated by the Massachusetts Executive Office of Health and Human Services (EOHHS), and its services are regulated through the Mass HIway Regulations. The HIway is overseen by a Health Information Technology (HIT) Council, and informed by consumer, provider, legal and policy, and technology advisory groups to promote a transparent multi-stakeholder engagement model.

Mass HIway Direct Messaging

The Mass HIway offers a secure Health Information Exchange (HIE) for all healthcare systems in Massachusetts, regardless of affiliation, location, or differences in technology. The HIway's Direct Messaging mechanism enables healthcare providers to exchange health information for the patients they serve. It is a cost-effective tool to improve care coordination, care quality, patient satisfaction, and public health reporting.

The Mass HIway's Direct Messaging solution offers doctors’ offices, hospitals, laboratories, pharmacies, skilled nursing facilities, and other healthcare organizations a cost-effective way to securely and seamlessly exchange vital health data electronically to better serve their shared patients.

HIway Connection Requirement

Massachusetts care providers are subject to the Mass HIway Regulations, including the HIway Connection Requirement. Currently, Acute Care Hospitals, Community Health Centers, and Medium/Large Medical Ambulatory Practices are subject to the HIway Connection Requirement, and must submit annual documentation attesting to their efforts to implement HIE use cases.

Statewide ENS Framework

An Event Notification Service (ENS) is a specialized form of HIE used to alert care providers about their patients’ Admissions, Discharges, and Transfers (ADT) to hospitals, Emergency Departments, and post-acute care facilities. The Mass HIway created and administers the Statewide ENS Framework, which is an ENS solution that serves all Massachusetts care providers.

Acute Care Hospitals must connect to the Statewide ENS Framework to submit Admission Discharge Transfer notifications (ADTs).

All other care providers are encouraged to participate in the framework as well to receive the alert notifications. To learn more about the Statewide ENS Framework, click here.

History of the Mass HIway

In October 2012, Massachusetts first launched the statewide electronic Health Information Exchange, The Massachusetts Health Information Highway (The Mass HIway). The Mass HIway provided Massachusetts care providers with a cost-effective Direct Messaging alternative.

In 2018, the Mass HIway released HIway 2.0, which is based on Orion Health's Communicate platform. HIway 2.0 aligns the HIway's Direct Messaging capabilities with modern interoperability standards, simplifies the connection process, and improves the user experience. Review the new features in the graphic shown below.

To enable providers to take advantage of the improved HIE capabilities, all HIway 1.0 users have been migrated to HIway 2.0.
