Community-based prevention interventions offer three distinct strengths. First, because the intervention is implemented population-wide it is inclusive and not dependent on access to a health care system. Second, by directing strategies at an entire population an intervention can reach individuals at all levels of risk. And finally, some lifestyle and behavioral risk factors are shaped by conditions not under an individual's control. For example, encouraging an individual to eat healthy food when none is accessible undermines the potential for successful behavioral change. Community-based prevention interventions can be designed to affect environmental and social conditions that are out of the reach of clinical services.
Four foundations - the California Endowment, the de Beaumont Foundation, the W.K. Kellogg Foundation, and the Robert Wood Johnson Foundation - asked the Institute of Medicine to convene an expert committee to develop a framework for assessing the value of community-based, non-clinical prevention policies and wellness strategies, especially those targeting the prevention of long-term, chronic diseases. The charge to the committee was to define community-based, non-clinical prevention policy and wellness strategies; define the value for community-based, non-clinical prevention policies and wellness strategies; and analyze current frameworks used to assess the value of community-based, non-clinical prevention policies and wellness strategies, including the methodologies and measures used and the short- and long-term impacts of such prevention policy and wellness strategies on health care spending and public health. An Integrated Framework for Assessing the Value of Community-Based Prevention summarizes the committee's findings.
