Data Across Sectors for Health (DASH) is a National Program Office (NPO) for the Robert Wood Johnson Foundation, led by the Illinois Public Health Institute in partnership with the Michigan Public Health Institute. At MPHI, the DASH NPO is located in the Center for Data Management and Translational Research (CDMTR). DASH supports collaborations that seek to improve the health of their communities, promote health equity and contribute to a Culture of Health by strengthening information sharing, engaging additional sectors and building sustainable data sharing capacity. DASH aims to create a body of knowledge and advance this emerging field by identifying and sharing opportunities, barriers, lessons learned, promising practices and indicators of progress for sharing data and information across and beyond traditional health sectors. DASH collaborates with programs across the country that have similar goals. DASH co-founded All In: Data for Community Health, a nationwide learning collaborative that helps communities build capacity to address the social determinants of health through multi-sector data sharing collaborations.
