Collective Medical – Certified Vendor: 

Collective Medical is the nation’s most effective ADT-based care collaboration network. Its strong Massachusetts and overall east coast presence yield proven results in improving ED optimization, behavioral care, and addressing complex or high-risk patients—including those with social determinants of health.

A Proven Solution for Massachusetts

Collective Medical captures over 95% of all ED and inpatient encounters at acute care hospitals across the Commonwealth, boasts the largest behavioral health provider and care coordination network, and brings asynchronous communication to medical communities—greatly increasing their ability to collaborate and better provide care.

Collective is unique in that it powers numerous other statewide ENS programs with proven value. In addition to ADT exchange, Collective has demonstrated improved outcomes in a number of use cases relevant for patients in Massachusetts. As examples:

  • In 2019, Collective helped Sturdy Memorial Hospital in Attleboro, Massachusetts reduce unnecessary ED utilization by enrolled behavioral health patients by 78 percent—drastically reducing ED boarding—through facilitating connections between ED physicians, case managers, and community behavioral health resources.
  • Aspire Health Alliance in Quincy, Massachusetts increased engagement rates by 150 percent using Collective in care management programs designed to meet MassHealth initiatives. This increase lead to better care for patients with behavioral health diagnoses, substance use disorder, and social determinants of care.
  • Nationwide, hospitals using the Collective platform to reduce unnecessary readmissions showed an overall 12% decrease in 2019 readmissions when a care insight was written for a patient on the platform. Collective is supported by 25 hospital associations across the country, with proven outcomes at hospitals, clinics, health systems, and other organizations throughout the US.
A Trusted Partner – Security and Compliance

Collective implements the highest healthcare standards and protocols to protect Sensitive Information and PHI across its network in accordance to HIPAA. Collective has been HITRUST certified since 2017, signifying its dedication to protecting data and information through state-of-the-art encryption in transit and at rest, and requires its downstream vendors and HIE partners to implement similar controls.

By including all federal and state regulations, standards, and frameworks, Collective ensures a comprehensive and flexible framework of prescriptive and scalable security controls.

As you consider Certified Vendors, we encourage you to inquire/discuss with potential vendors how long the Certified Vendor has been HITRUST Certified (one of the main security requirements of EOHHS to become Certified).
