In late 1972, a survey of Mayo Graduate School alumni was undertaken to determine if changes were needed to make the internal medicine residency program more relevant to such medical practice in the 1970s. Responses were obtained from 783 of the 1,109 former residents in internal medicine to whom questionnaires were sent. Although nearly half of the responders indicated a subspecialty component to their practice, 73% indicated they spend more than half of their time in the delivery of primary care; an additional 15% reported that primary care occupied from 20% to 50% of their professional time. There was agreement that more general internists are needed and that better geographic distribution of physicians would improve health care delivery.
