Rapid collaborative health impact assessment: a three-meeting process.

A three-meeting process for collaborative health (inequality) impact assessment [H(I)IA] of a proposed new road is described in which local residents worked with professionals to produce a jointly agreed evidence-based report. Collaborative H(I)IA provided a forum for people to express fears that they believed had been ignored, and for planners to understand the concerns of the community and the health impacts of developments on the most vulnerable. The report has been passed to those who will influence the future of the road development plan and a decision is awaited.
