Rene Cabral-Daniels, JD, MPH

Rene Cabral-Daniels, JD, MPH
Community Care Network of Virginia

My professional experience has involved leading high-level positions that focus on assuring medically underserved populations have not only access to quality health care services, but that they have a voice in the health care policy development.

As an attorney for the Centers for Medicare and Medicaid Services (CMS), I was the lead attorney for outpatient prospective system payments, CMS communication activities and all payment systems disproportionately impacting rural areas. I competed against CMS attorneys in being assigned a special temporary duty assignment where I drafted policy shaping CMS’ efforts to comply with the Balanced Budget Act of 1997, which had the greatest number of changes to the Medicare program before passage of the Patient Protection and Affordable Care Act.

I also served as the Executive Advisor to the Health Commissioner of the Commonwealth of Virginia. In that role I lead agency-wide programs, including one to improve Information Technology systems for its 36 local health districts. While employed at the Virginia Department of Health, I directed the Office of Health Policy and Planning (OHPP), which included the Offices of Rural Health, Minority Health and Primary Care. The Office of Primary Care administered Virginia’s FLEX program, which includes all Critical Access Hospitals in the Commonwealth. The OHPP was also responsible for educating the Virginia legislature on telemedicine payment issues and was successful in securing Medicaid payment for providers.

Currently, I am the CEO of Community Care Network of Virginia, Inc. (CCNV). CCNV’s shareholders are all 26 federally qualified health centers located in Virginia. The 26 health centers have over 112 sites and served over 300,000 patients in 2015, the majority of whom are members of medically underserved populations. CCNV leads IT services on behalf of Virginia’s FQHCs. CCNV is currently preparing to elevate its role by engaging in efforts to programmatically assist shareholders with value based payment efforts. In addition to serving CCNV shareholders, CCNV also uses automated systems to perform credentialing and other services to clients in 23 states.

Sumit Nagpal

Sumit Nagpal
Chief Architect
LumiraDx USA

LumiraDx represents the fifth generation of my work, which began while working with Steve Jobs and NeXT, Inc. in the early 1990s. From there, I led my first company, Wellogic, to create one of the first longitudinal medical records across major departmental systems in a best-of-breed hospital in Boston, a never before accomplished feat.

In 2011, faced with tremendous opportunity and growth as the US Affordable Care Act was well under implementation, I joined hands with a top fortune company Alere, Inc. to bring Alere's vision of enabling patients to participate actively in the own care in collaboration with their care team to life. Today, I have taken my vision private once again, with the strength and backing of a trio of industry leaders, and I am now helping to drive practical interoperability and standards adoption in the European and US markets as well as globally.

While humble in description, my current work will be the game changer to finally get the delivery and affordability of healthcare to each and every inhabitant in the World and where best practices will be boundarless in scope and delivery. Good compassionate healthcare is a right, not a privilege, and every inhabitant in the World needs the same access and quality. My current work supports this effort. This vision is also supported by my collaboration with Sir Richard Branson, Virgin Inc. one of LumiraDx's clients among many others. Our shared vision is to change the way people are treated for healthcare and its delivery regardless of their socio-economic situation.

I believe in the mission of HIMSS. I am extremely impressed with the HIMSS North America leadership having watched the leadership transform HIMSS North America nothing short of phenomenal to further greatness helping the masses. I want to use my diverse national and international skill sets acquired through my career thus far (in industry and working with various governmental agencies here and in the World), to help HIMSS North America provide support for all healthcare stakeholders.
