In this study of the physical facilities of the nation's health professions schools, all schools of dentistry, medicine, optometry, osteopathy, pharmacy, podiatry, public health, and veterinary medicine, and all parent institutions of the schools, were surveyed in May of 1973. The major goals of this pioneering survey were to assess the nature and use of existing, under construction, and planned facilities, and to forecast the anticipated replacement or expansion of facilities in the following decade. At the time of this writing, three years after the first survey, very few of the data are obsolete. Information on nonclinical instruction facilities has to do with amount, condition, and perceived needs for room types: classrooms, class laboratories, research and research training space, library space, auditoria, faculty offices, administrative areas, animal facilities, and other kinds of space. Clinical teaching facilities available to the schools are also inventoried in square footage and in terms of beds, examination rooms, and ambulatory patient stations. Analyses are made of resource utilization. Census data are projected to determine use of facilities and output of health professionals in future years. (Author/MSE)
