The Lives Saved Tool (LiST) estimates the impact of scaling up on maternal, newborn, and child health, and nutrition (MNCH&N) interventions in low and middle income countries. Users - including NGOs, government partners, researchers, project planners and graduate students – have used LiST for advocacy, evaluation, and strategic planning. LiST was developed by the Institute for International Programs at Johns Hopkins Bloomberg School of Public Health and funded by the Bill & Melinda Gates Foundation - It is housed within Spectrum, a software package maintained by Avenir Health.
LiST calculates changes in cause-specific mortality based on intervention coverage change, intervention effectiveness for that cause, and the percentage of cause-specific mortality sensitive to that intervention. Coverage data come from large-scale household surveys - typically Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS) - as well as WHO/UNICEF and the WHO/UNICEF Joint Monitoring Programme for Water Supply, Sanitation and Hygiene (JMP). Default effectiveness values come from systematic reviews, meta-analyses, Delphi estimations, and randomized control trials based upon the Child Health Epidemiology Reference Group (CHERG) guidelines. Baseline mortality is drawn from country-level estimates from WHO, UNICEF, UNFPA, World Bank Group and the United Nations Population Division and the UN Inter-agency Group for Child Mortality Estimation (IGME). These high quality data sources as inputs translate into estimates that can be trusted. Additionally, users who have more recent or better data can easily replace default data with their own. A full explanation of the LiST methodology is explained in a 2013 paper by Walker et al.
