The Lives Saved Tool (LiST), developed by the Institute for International Programs (IIP) at Johns Hopkins Bloomberg School of Public Health and funded by the Bill & Melinda Gates Foundation, is a model that estimates the impact of scaling up health and nutrition interventions on newborn, child, and maternal health.

LiST is a part of Spectrum, a software package maintained by Avenir Health. The model has been used for over 10 years, and is regularly updated to incorporate the latest evidence from the scientific literature and household survey data. To learn more about the Lives Saved Tool,
