Coalitions for impacting the health of a community: the Summit County, Ohio, experience.

Community coalitions have the potential to catalyze important changes in the health and well-being of populations. The authors demonstrate how communities can benefit from a multisector coalition to conduct a community-wide surveillance, coordinate activities, and monitor health and wellness interventions. Data from Summit County, Ohio are presented that illustrate how this approach can be framed and used to impact community health positively across communities nationwide. By jointly sharing the responsibility and accountability for population health through coalitions, communities can use the Health Impact Pyramid framework to assess local assets and challenges and to identify and implement programmatic and structural needs. Such a coalition is well poised to limit duplication and to increase the efficiency of existing efforts and, ultimately, to positively impact the health of a population.
