3Health care in the U.S. is in the throes of shifting its emphasis from an illness care system to one focused on health promotion and disease prevention. The convergence of multiple economic, political, and social factors including Healthy People 2020, the Obama Administration's National Prevention Strategy, and the Patient Protection and Affordable Care Act (ACA) provide a "road map" for improving the health of the public. Public health nurses should be in the forefront of health care to lead change in all sectors from public to private and local to global. This revised edition of Public Health Nursing: Scope and Standards of Practice looks to the future of public health nursing and provides essential guidance in the form of standards and competencies for generalist and the advanced public health nurse. This is a must-have title for public health nursing practitioners, educators, students, researchers and others directly involved in public health. Employers, insurers, lawyers, regulators, policy makers and stakeholders will find value in referencing this publication.
