Surgeons and operating rooms: underutilized resources.

A classification of surgical procedures, based on degree of complexity and the need for facilities and personnel, was applied to all 50,782 surgical interventions performed in the Valle del Cauca, Colombia during 1974. Three-fourths of all operations were of low levels of complexity, and most could be performed on an ambulatory basis with immediate discharge after recovery from anesthesia. Mean numbers of operations per year for surgical specialists and other physicians were 119.7 and 18.1, respectively. The 76 existing operating rooms were utilized only 41.6 per cent of the time. The implications of underutilization of personnel and facilities and low productivity of surgeons are discussed.
