The Five Steps in the Health Impact Assessment Process

0 Comment

The HIA involves the participation of public stakeholders and lays down a social model of health and well being with a focus on equity, sustainability and social justice (Dora, 1999, p. 1686-1689). The procedure involves the following steps:
a. Screening: Helps to determine the potential health implications of a policy under consideration to determine whether the HIA will likely to succeed and add value. It will define the domain of the specific project, program or policy decision that the HIA will address (The HIA Process: Health Impact Project, 2011). The HIA specific for Parramore community should evaluate the impact of the community’s redevelopment and improvement on the health of its residents, particularly in chronic health issues. At least one individual per family in the Parramore Community suffers from chronic diseases. Screening may also provide information about earlier unrecognized health issues and will predict the feasibility of available sources like money, stakeholder interests, and political will.
b. Scoping: The key health issues and public concerns are identified and considered in this step so the objectives and aims of the HIA are formulated. The health determinants must also include the environmental and social factors. The outcome will address the health effects that the HIA will address, the person/s that would be affected by the HIA policy, and in what way?
c. Appraisal and Assessment: With respect to the defined scope all the available evidence gathered will be used to estimate the potential health gains or losses. This indicates there should be a description of the baseline health of people and groups affected by HIA and then predicting the potential health effects in them. The baseline analysis will not only evaluate the causes of illness but also the associated factors like local economy, environmental quality, and food accessibility will all be in question.
