HD4A Data Providers and Projects
This resource document includes a list of all Health Data for Action data providers and projects.
Health Data for Action (HD4A) is a signature research program of the Robert Wood Johnson Foundation (RWJF) managed by AcademyHealth. HD4A aimed to reduce the barriers often faced in accessing data by serving as a conduit between data owners and interested researchers. Through each HD4A funding opportunity, RWJF made valuable data from unique data owners available to researchers.
Since the program’s inception in 2017, the Foundation has awarded over 60 HD4A grants to researchers to study issues such as care coordination and quality, reproductive health, health care payment structures, chronic and complex conditions, and access to care and treatment, among others. The HD4A program announced the final grantees under the program in 2024, and the program will wind down by the end of 2026. Researchers have utilized available data from 20 different providers, listed in the publication above, to conduct their studies. Additional information about each of the funded projects can be found here.
