The purpose of this study was to support the development of a standardized methodology for estimating averted premature death and disability (i.e. averted Disability Adjusted Life Years or aDALYs) from cookstove intervention programs in regions dependent on solid fuels for meeting their household energy needs. It took place in Lao PDR to measure health-related outcomes of improved cookstove dissemination and then apply an innovative model for measuring aDALYs, called the Household Air Pollution Intervention Tool (HAPIT), to quantify the health impacts.
