National COVID Cohort Collaborative (N3C)

What is N3C?

N3C is an analytics platform that includes the largest repository of COVID-19 clinical data in the world contributed by over 50 health care organizations nationwide, including the UVM Health Network. In addition to the vast amounts of data available for coronavirus research, N3C features opportunities for team science and collaboration with experts in statistics, machine learning, informatics, pharmaceuticals, and the many clinical domains. It also allows our investigators a front-row seat in what is expected to be a sea-change in health research.

N3C was officially launched in September 2020 and is funded by the National Center for Advancing Translational Sciences (NCATS). UVM, through its leadership in the Northern New England Clinical & Translational Research (NNE-CTR) Network, joined a larger national network of IDeA-CTRs to contribute data to the platform.

Over 6 billion data rows are available in N3C, containing information about: 1) patients, 2) their diagnosis, 3) their treatments, 4) their lab results, 5) their healthcare provider, and more. Thus, this rich dataset contains a wide array of information electronic health records contain about each COVID-19 case.

What’s Available

The N3C enclave currently holds data related to roughly:

  • over 300 million visits,
  • nearly 600 million clinical observations,
  • over 300 million procedures; and
  • over 3 billion laboratory results.

The data originate from national health records of more than 6 million COVID-19 patients, over 2 million of whom were confirmed to have COVID-19. More than 80 organizations have agreed to contribute health records for the effort.
