Control of healthcare in USA

Who controls health care? As you have learned, the U.S. does not have a central agency to manage and govern health care delivery. Rather, multiple parties have varying responsibilities for and interests in health care delivery. Therefore, this question deserves thoughtful consideration and raises many additional questions about healthcare in the United States.
To prepare for this assignment: you will be conducting a brief historical review or timeline regarding how healthcare delivery has changed and adapted throughout history. However, this isn’t a history lesson. Talk about the changes over time, but more importantly, how have these changes affected healthcare administrators today? How have the changes in healthcare delivery had an impact on you personally, as a current administrator, or how WILL it affect you once you’re in an administrative role? You will consider how the control of health care delivery has shifted over time from the preindustrial era until today.
Think about the changing roles and responsibilities of various individuals and institutions, such as:
Physicians
Hospitals
Insurers/managed-care organizations
Regulators
Government payers (Medicare and Medicaid)
Also, consider how the issue provides opportunities and challenges for healthcare administrators.
