In the developing world, the use of timely, high-quality data is essential to strengthening health systems and providing efficient health services. Vital Wave was engaged by the Bill & Melinda Gates Foundation in a Data Use Partnership to improve information systems and increase the use of data in health care delivery in Ethiopia and Malawi. Vital Wave supported the Ministry of Health in Ethiopia in developing a strategy for their Information Revolution as well as an implementation plan. In Malawi, Vital wave supported the Ministry of Health by providing a technical review of their HIS improvement and interoperability plan. This project was a partnership with PATH who is providing similar support in Tanzania.
