The evolution of medical staff credentialing.

As medicine has developed more and more into a business, the process of medical staff credentialing has evolved. Today, physicians need to be affiliated with a hospital or other health care entity in order to practice. Health care entities, in turn, must be able to ensure quality of care and efficiency. The mechanisms that have developed to achieve these purposes comprise the process of medical staff credentialing as it now exists and will shape the continued evolution of credentialing in the future.
