CDC defines a community health improvement plan (or CHIP) as a long-term, systematic effort to address public health problems based on the results of community health needs assessment activities and the community health improvement process. A plan is typically updated every three to five years.
The Public Health Accreditation Board (PDF) defines a community health improvement plan as a long-term, systematic effort to address public health problems on the basis of the results of community health assessment activities and the community health improvement process. This plan is used by health and other governmental education and human service agencies, in collaboration with community partners, to set priorities and coordinate and target resources. A community health improvement plan is critical for developing policies and defining actions to target efforts that promote health. It should define the vision for the health of the community through a collaborative process and should address the gamut of strengths, weaknesses, challenges, and opportunities that exist in the community to improve the health status of that community.
