Improving the health of a community takes the support and participation of multiple organizations and stakeholders from across the community. Hospitals are not expected to do this work alone or to serve as the sole funder. However, one of the key goals of the Navigator is to support hospitals in addressing the social determinants of health, those factors that impact patients with complex disease burdens and cost hospitals the most. CHI efforts offer a tremendous opportunity for hospitals to position themselves within a health system that is based on value and outcomes more than on the volume of services provided. By collaborating with other organizations that support or conduct community health assessments, hospitals can maximize their resources and efforts for greater impact on health and well-being. This brief from the New York Academy of Medicine provides examples of the complementary roles of various sectors, including health care, public health, and community partners. Regarding a backbone organization, ideally hospitals, working with community stakeholders and other organizations, can determine a structure that benefits all who are working to improve community health.
