Relationship Between Healthcare Delivery, Public Policy, and Public and Community Health provides an examination of public health policy and its implications for public and community health services. This content focuses on an exploration of the policy development process, including the legislative process. Public and private health politics are complex and affect services, professional practice, and the healthcare workforce. The policy development process requires engagement from many stakeholders, individual healthcare providers and organizations, and must include input from health professional education, communities and government organizations, insurers, those involved in health policy and health research, and consumers. As with all facets of healthcare services, policy development must consider diversity, equity, and inclusion; the social determinants of health; disparities; population health; and vulnerable populations. Individual topics addressed in the guide include the impact of COVID-19 on populational health management and public policy, health literacy, the implementation of public policies, policy funding, and more. Relationship Between Healthcare Delivery, Public Policy, and Public and Community Health is part of the Cognella Series on Public and Community Health Nursing, a collection of concise, informative guides that explore critical topical areas, their nursing application, and their relationship to nursing practice.
