The Massachusetts Executive Office of Health and Human Services (EOHHS) will hold the public forum to discuss draft certification criteria for the EOHHS Market-based ENS Initiative. EOHHS is releasing this Draft certification criteria to evaluate a vendor’s competency to participate in the statewide Event Notification Services (ENS) framework for public comment.

EOHHS seeks to develop timely statewide ENS across the Commonwealth in order to improve health care delivery, quality, and care coordination. EOHHS seeks to leverage the gains existing ENS service providers have made, to create a statewide ENS framework. The proposed ENS framework seeks to promote data sharing to increase access to ENS for providers of all sizes, to streamline the provider experience by allowing for single submission and single reception of data, and to improve timing for the flow of data.


In October 2012, Massachusetts launched the statewide electronic health information exchange, The Massachusetts Health Information Highway (The Mass HIway). The Mass HIway offers doctors’ offices, hospitals, laboratories, pharmacies, skilled nursing facilities, and other healthcare organizations a way to securely and seamlessly transmit vital data electronically.


This meaningful exchange of information can enable the Commonwealth’s care community to:

  • Positively influence care coordination and delivery
  • Avoid readmissions and medical errors
  • Reduce administrative costs and duplicative testing
  • Enhance communication among providers
  • Increase patient engagement
  • Improve public health reporting and analytics

The Mass HIway is open to all interested providers, hospitals, and other organizations within the healthcare community regardless of affiliation, location, or differences in technology.
