The Affordable Care Act requires tax-exempt hospitals to conduct community health needs assessments (CHNAs) every three years, complete with implementation strategies to improve the health of the communities they serve. CHNAs ensure that hospitals have the information they need to make impactful investments in community benefits, and to coordinate these investments with external efforts to improve community health and well-being. By statute, the CHNAs must take into account input from “persons who represent the broad interests of the community served by the hospital facility.”
