Healthy public policy plays an essential role in a comprehensive public health
approach to preventing cancer and chronic disease. Public policies spread
through the ‘policy diffusion’ process, enabling governments to
learn from another’s enacted policy solutions. The Prevention Policies
Directory (the Directory), an online database of municipal,
provincial/territorial, and federal cancer and chronic disease prevention
policies from across Canada, was developed to facilitate the diffusion of
healthy public policies and support the work of prevention researchers,
practitioners, and policy specialists. This information technology solution was implemented, through a participatory engagement approach, as a communication channel or policy knowledge transfer tool. It also addressed the
intrinsic shortcomings of environmental scanning for policy surveillance and
monitoring. A combination of quantitative web metrics and qualitative anecdotal
evidence have illustrated that the Directory is becoming an important tool for
healthy public policy surveillance and policy diffusion in Canada.
