Health Impact Assessments are an important tool to help policymakers perceive the potential positive and negative contributions of decisions to public health. While they have been increasingly used in the United States, studies have not examined intermediate effects. Using key stakeholder interviews, this manuscript examines policy outcomes and other related effects of the HIA 21 months after completing a Health Impact Assessment Report around connectivity policy. Further, it reflects on the measurement of these effects as part of the monitoring and evaluation stage of the Health Impact Assessment process.
