Community Health Assessment
The fundamental purpose of public health is defined by three core functions: assessment, policy development and assurance. Community health assessments (CHAs) provide information for problem and asset identification and policy formulation, implementation, and evaluation. CHAs also help measure how well a public health system is fulfilling its assurance function. A CHA should be part of an ongoing broader community health improvement process. A community health improvement process uses CHA data to identify priority issues, develop and implement strategies for action, and establish accountability to ensure measurable health improvement, which are often outlined in the form of a community health improvement plan (CHIP). A community health improvement process looks outside of the performance of an individual organization serving a specific segment of a community to the way in which the activities of many organizations contribute to community health improvement.
