Public health in a managed care environment.

As the health care system moves in a new direction, toward managed care, the critical role of public health in society's efforts to mitigate illness and the realization of health become more apparent. Indeed, the public health problems of this era will not yield to simple solutions. They require a multitude of resources, both human and material, and a myriad of services derived from these resources. Public health's role is to serve as the government's presence in assessing health status, developing policy, evaluating the effectiveness of policy implementation, and assuring access to and quality of comprehensive health services. Increasingly, public health must coordinate a wide array of systems in both the private and public sectors to fulfill its purpose.
