The Global Health Impact Assessment and Evaluation Group – IMPACThealth, is an interdisciplinary, interinstitutional, and intercultural research group dedicated to generating robust evidence on the health impacts of public policies, programs, and interventions. Our work centers on Health Impact Assessment and Evaluation (HIAE) methods—a systematic process that draws on multiple data sources and analytical approaches to assess how a policy, program, or project affects population health. We use cutting-edge tools and methodologies for HIAE, integrating ex-post (retrospective) and ex-ante (forecasting) evaluation techniques. Our work leverages large longitudinal datasets, quasi-experimental methods, and large microsimulation models, among many other approaches.
