Health workforce information systems have been proliferating in countries to address different health workforce needs, including management systems in the public and private sector, regulatory information systems including professional council registration and licensure, and training information systems. However, these different systems are not reaching their full potential due to failure to work as an interoperable whole. Presented at the GETHealth Summit in Dublin, Ireland (November 13–14, 2014), this poster describes work to develop a new data exchange standard, Care Services Discovery. This technology is open and collaborative, available for support by a wide variety of technologies, including iHRIS, DHIS 2, and UNICEF’s RapidPro platform. Open source technologies and open standards approaches make a formidable combination to address information needs.
