Integrating health into planning often uses the approach called evidence-based practice. An article on this topic by some of the folks from Design for Health, including me, is currently available for free: http://www.informaworld.com/smpp/content~db=all~content=a918403162~frm=titlelink. It was a finalist in the Association of European Schools of Planning Best Paper Prize: http://www.aesop-planning.com/Prize_BBP.html

Can the craft of planning take advantage of a growing body of planning-relevant research? Evidence-based practice proposes a better connection between research and professional work, but raises several concerns about the character of valid evidence, the strength and clarity of planning research, and inequalities in the available resources for integrating research into planning practice. Much of planning practice is a reflective craft where skills of mediation, negotiation, listening, and framing are prominent. As part of the planner's work employing these skills, however, there is a valuable role for research-generated evidence to inform decision making. Evidence-based practice needs careful implementation but it can enrich the field of planning by linking research to practice.
