This is where a large amount of HIA work is carried out. An example of appraisal can be drawn from a health and equity assessment of a large oil project in Africa. The work began with a panel of experts (the World Bank required the Chad and Cameroon Governments to hire a panel of experts to guide the assessment process) who examined the proposal in detail. The panel drew on a variety of documents provided by the consortium that included information on a limited number of determinants of health social and economic issues, wildlife and biodiversity (note that HIA would usually assess more determinants of health than this). The papers also listed specific health hazards and diseases in the project area. The relationships between the determinants of health and key elements of the proposal were investigated (often laid out in a table/grid like fashion for clarity).
