To publicize HHS data and improve health data transparency, community outreach events have been held all over the country. These include health data “boot camps” where experts are present to explain data and technology developers and community leaders interact to invent new uses of data for important challenges in their health community. Additionally, more than 20 health data developer challenges have been held across the country engaging technology developers from small and large companies to work together on creating new applications. HHS has also promoted the use of code-a-thons – activities that bring together computer technologists who form teams to work on new applications in a common setting where they can interact with data experts. Nearly a dozen code-a-thons have been held in the last year. Both activities involve prizes and recognition awards that are made to the best apps developers.
