摘要:The Canadian Cancer Society and the National Cancer Institute of Canada have charged their Centre for Behavioral Research and Program Evaluation with contributing to the development of the country’s systemic capacity to link research, policy, and practice related to population-level interventions. Local data collection and feedback systems are integral to this capacity. Canada’s School Health Action Planning and Evaluation System (SHAPES) allows data to be collected from all of a school’s students, and these data are used to produce computer-generated school “health profiles.” SHAPES is being used for intervention planning, evaluation, surveillance, and research across Canada. Strong demand and multipartner investment suggest that SHAPES is adding value in all of these domains. Such systems can contribute substantially to evidence-informed public health practice, public engagement, participatory action research, and relevant, timely population intervention research. WE ENVISION A FUTURE IN which a comprehensive, coherent macrolevel system (integrated across national, provincial or state, and local levels) will enable communities to take evidenced informed action to improve the health of citizens at the population level. This system will enable communities to pinpoint intervention opportunities with the highest potential impact, identify the most optimal intervention approaches, access intervention resources, and use local data collection and feedback resources to continuously guide, evaluate, refine, and learn from their work. The elements of such a system are taking shape. For instance, the capacity to synthesize and disseminate intervention research data is being built internationally. 1 , 2 In Canada, the country’s Public Health Agency 3 and the Canadian Tobacco Control Research Initiative 4 are using a model to review interventions that take into account not only evidence, but also plausibility and practicality. 5 A local data collection and feedback system is an integral component of the macrosystem we have envisioned. The School Health Action Planning and Evaluation System (SHAPES), initiated in 2000, was designed to support the collection and use of local data for planning, evaluation, and field research and to help align and integrate these activities with policy and practice. As described subsequently, we have discovered that SHAPES is also useful for surveillance. Our goal here is to stimulate interest and collaboration in the development and use of local data collection and feedback systems to improve public health.
