The eighth edition of this best-selling text, valued for its concise and balanced introduction to the U.S. health care system, is entirely updated to reflect alterations to health care services, delivery, and financing resulting from the Affordable Care Act (ACA). The text describes how our health care system currently functions, the key forces that led to its structure, and the influences likely to shape the industry during the next 5 to 10 years. With an emphasis on policy development, the authors underscore the fluidity of the system and examine the debates and conflicts that have shaped health care changes and influenced American values and belief systems. Other new areas of focus include an assessment of who uses health care and in what way, health care trends, and a forecast for the health care system of the future. The text elucidates the basic building blocks of the health care system, including its components, organization, services, and financing. It describes the ongoing evolution of the system since the passage of the ACA, development of accountable care organizations (ACOs), and uneven acceptance of Medicaid expansion by states. Organized to facilitate understanding of concepts at work, the text provides health care students with a clear road map of the field in which they will practice, so they can position themselves to navigate the upcoming changes.
