Center for Health Impact Evaluation (CHIE)

Welcome to the Center for Health Impact Evaluation website! We are part of the Chief Science Office at the Los Angeles County Department of Public Health (DPH). We work with DPH and external partners to conduct Health Impact Assessments, studies that assess the health and other impacts of policies, plans and projects in sectors where health is not necessarily the main focus. We also collaborate with other DPH programs to conduct economic evaluations and other analytic studies of public health programs and policies.  

To conduct our studies, we rely on a variety of quantitative and qualitative tools such as statistical methods, simulation modeling, focus groups, and interviews with key stakeholders. Our work helps the Department of Public Health, other agencies, and the general public assess the degree to which our programs are achieving their goals and understand the potential impacts of future policy decisions.
