How much aid really supports global health goals?

New research published in The Lancet Global Health shows that four high-profile estimates – from the Countdown to 2015, the Organisation for Economic Co-operation and Development (OECD), the Institute for Health Metrics and Evaluation (IHME), and the G8’s Muskoka Initiative – indicate substantially different levels and trends in aid for reproductive, maternal, newborn, and child health (RMNCH), especially for individual donors and recipient countries. This can have major implications for how we assess past aid efforts, which could in turn affect future aid policies and health outcomes. This new research offers important insights for how we track aid for the Sustainable Development Goals (SDGs); for the Global Strategy for Women’s, Children’s, and Adolescent Health; and for any global health goals.
