Managed care. Origins, principles, and evolution.

Managed care has entered the lexicon of healthcare reform, but confusion and ignorance surround its meaning and purpose. It seeks to cut the costs of health care while maintaining its quality, but the evidence that it is able to achieve these aims is mixed. As well as raising awareness and understanding of the issues surrounding managed care, this series considers whether managed care is desirable for the NHS. Developed in the United States as a response to spiralling healthcare costs and dysfunctional fragmented services, managed care is not a discrete activity but a spectrum of activities carried out in a range of organisational settings. Due to its constantly changing nature, managed care is a slippery concept--but all its permutations have in common an attempt to influence and modify the behaviour and practice of doctors and other health professionals towards cost effective care. Whatever potential managed care may hold in this regard, careful appraisal of its implications is essential.
