This pilot project was designed to demonstrate the feasibility of exchanging professional personnel of a medical school and a community hospital as a method of stimulating the internal communications practices of physicians at the community hospital. The impact upon the attitudes and educational policies and activities of community hospital physicians was the chief focus of the program, but the effects upon the quality of medical care at the community hospital and the attitudes of the staff at Jefferson Medical College were also examined. A rotating schedule was set up and specialists from both institutions visited the other facility for a period of one week. The staff at the Community Hospital was found to be divided into two groups, teaching and nonteaching, and there was little interdepartmental cross-fertilization of ideas. The program resulted in a request by the Community Hospital for affiliation with the Medical College and in a greater awareness by the Medical College staff of the problems of physicians at community hospitals.
