The phrase “evidence-based” has become ubiquitous in state government circles. The concept is simple: Decisions, in an evidence-based system, are made based on validated prior experiences and research, rather than just on opinions, anecdotes and ideologies. But, “often that work hasn’t included health,” said Rebecca Morley, director of the Health Impact Project, a collaboration of the Robert Wood Johnson Foundation and the Pew Charitable Trusts. Morley’s efforts, along with others, have been to encourage and assist states and localities in developing so-called health impact assessments, or HIAs, which are “a very specific tool for bringing health issues to decision making,” she explained. HIAs use a variety of procedures, methods and tools to evaluate the potential health effects of a policy, program or project, according to the World Health Organization.
