Community Health Needs Assessment
California requires nonprofit hospitals to conduct assessments to evaluate the health needs of the communities they serve.

A hospital may conduct—either alone, with other health care providers, or through other organizational arrangements—an assessment that evaluates the health needs of the community the hospital serves. At a minimum, the assessment must describe the process employed by the hospital to consult with community groups and local government officials in identifying and prioritizing community needs that can be addressed directly by the hospital, and those that the hospital can address in collaboration with other entities, or through other organizational arrangements. The assessment must be updated at least every three years. Cal. Health & Safety Code §127350(b).
