A public health nursing model

Public health nurses are in a strategic position to maintain, promote, and protect the health of populations both now and in the future. In the changing health care environment of the 1990s, defining the expanding and evolving role of public health nursing assists in the effective utilization of public health nurses. During a time when the health care environment is emphasizing the protection and promotion of health, access to health services, and prevention of illness, it is necessary for public health nurses to be in the forefront in the changing focus to primary prevention. Therefore, a model for public health nursing is proposed to provide a framework for defining public health nursing roles and practice. A flowering tree is one symbol of public health nursing. The tree consists of seven parts symbolizing nine public health nursing concepts. This model is proposed to articulate clearly the capacity of public health nursing within today's ever-changing environment and to provide a framework for public health nursing theory, public health nursing practice, policy development, and public health research.
