Training in academic internal medicine occurs in both the university and community settings. Besides teaching the next generation of physicians, academic medicine conducts cutting-edge research, provides high-level care for patients, and employs millions of Americans. Many academic centers provide care for indigent patients. Often, medical schools and teaching hospitals are affiliated with programs for other health providers, such as nurses, public health officers, and allied health professionals. This combination of medical schools, other providers, and teaching hospitals forms the foundation of American medicine.
