Reducing the burden of maternal, fetal, and neonatal mortality around the world depends, in part, on having the right tools for the job. As part of the MANDATE project, RTI is assembling an inventory of technologies commonly used to save maternal, fetal, and neonatal lives in all settings around the world. While far from exhaustive, the inventory gives a sense what is used today, and where. In the process, the MANDATE team is identifying gaps in the toolkit, and resulting opportunities for innovation. The technologies profiled here constitute a starting point for discussion about technologies, both existing and yet to be invented, that have the greatest potential to save lives around the world. We invite you to review these technology briefs and Email us any comments.
