The teaching hospital is one associated with a medical school. Teaching hospitals are large, with a range of from 300 to 200 beds. These hospitals always have interns(实习医师) and residents(住院医师) and additionally have medical students on the hospital wards. They have superb technical resources, and it is here that the most extraordinary events of medicine take place. Open-heart surgery, transplantation of kidneys, elaborate(精致的) nurseries for the newborn, support for management of rare blood diseases, and other wonderful achievements are all available here. Dozens of people may be concerned with the well-being of a particular patient. Important medical decisions are thoroughly discussed, presented at conferences, and reviewed by many personnel.

On the other hand, the quality of personal relationships at teaching hospitals is variable. Many patients feel that they are treated in an impersonal way, and that their laboratory tests receive more attention that their human and social problems. Since these institutions are on the frontier of medicine, there is a tendency to emphasize the new and elaborate procedures, when older and more modest ones might have served as well. With the inexperience of some members of the care team, there is a tendency to order more laboratory tests than what would have been ordered for the same condition in a private hospital. The sick patients are sometimes confused by having to relate to a large number of doctors and students. Medical educators are concerned with such criticisms and have to correct some of the problems. However, some excesses(超额) of technological medicine still occur in these institutions.
