Manifest MedEx Network Now Sharing Health Records For More Than Half of Californians

Nonprofit network provides critical COVID-19 services including COVID-19+ alerts, tools to identify high-risk patients, and longitudinal care records

Emeryville, Calif. – October 19, 2020 — Nonprofit health data network Manifest MedEx (MX) is announcing today that it is now sharing health records for 23 million people, more than half (58%) the population of California, through its network of over 600 participating hospitals, health plans and provider organizations.

Significant recent milestones for MX include:

Connecting to Carequality via the eHealth Exchange Hub

  • In line with its mission to help California’s health leaders improve healthcare, reduce costs and enhance health, MX records are now available to 1,826 health organizations in California participating in Carequality. Leading health systems in California are querying MX and receiving high volumes of data. In July the MX network was queried 400,000 times by Kaiser Northern California, 250,000 times by Sutter Health, and 200,000 times by the University of California San Francisco (UCSF).
  • Paul Matthews, Chief Technology Officer and Chief Information Security Officer for OCHIN said: “OCHIN is pleased to be working with Manifest MedEx to exchange data through the eHealth Exchange National Network in order to understand care gaps. We believe standard connection to national frameworks for health information exchange reduces costs and improves efficiencies for the entire health system.”
  • MX CEO Claudia Williams said: “Participating in Carequality is an easy and affordable way to expand the reach of our network and bring value to California’s health ecosystem. Carequality is a great complement to our robust suite of services including population health tools, event notifications, readmissions reports, claims data and COVID-19+ alerts available to our participants.”

Additional Milestones

  • Use of MX services tripled since February, as hospitals and ambulatory providers strive to stay on top of patient care in the midst of the COVID-19 pandemic. MX introduced new COVID-19+ alerts to notify primary care teams when their patients test positive, and tools to rapidly identify patients at higher risk of COVID-19 complications.
  • MX expanded its participant base, adding OCHIN and its broad network of safety net clinics. MX expanded its footprint in Los Angeles by welcoming seven hospitals from the Alta Hospital System. In addition, MX adds an average of 3 new ambulatory PCPs and specialists to its network every day, including Bay Area Community Health, which serves more than 100,000 patients.
  • Through the state’s Cal-HOP program MX is delivering millions of dollars in connectivity incentives to providers and hospitals across California. By becoming an MX participant, California hospitals can receive up to $65,000 each while also ensuring compliance with CMS’s new ADT event notification requirements which go into effect May 1, 2021.
  • Especially valuable in light of both the COVID-19 pandemic and recent wildfires, MX delivers over 300,000 patient notifications each month alerting care teams when a patient is admitted to the hospital, discharged, transferred, or tested positive for COVID-19. These notifications reduce readmissions and improve care, ensuring patients receive needed support after hospitalization or when they are quarantining at home. Seamless care and follow up has never been more important.
