The number of office visits, operations and deliveries performed by obstetrician-gynecologists is higher in areas where there are fewer physicians, higher for specialist groups than for solo practice arrangements, and higher for specialists 40–54 years of age than for those in younger or older age groups. Younger specialists perform more deliveries and older specialists perform more major operations. These several factors appear to operate independently of each other. The delegation of office tasks is related to the ratio of nonphysicians to physicians in the office setting and to the presence of a registered nurse among the employed workers. Hospital task-delegation is most frequent in hospitals without house staff but is also influenced by medical customs of the area. The nature of the tasks delegated in office and hospital practice and the frequency with which tasks are delegated are not closely related to the level of decision making and the training required to perform the task.
