Obstetrician-gynecologists are primary physicians to women. I. Practice patterns of Michigan obstetrician-gynecologists.

Michigan obstetrician-gynecologists were asked to complete questionnaires designed to determine what kinds of medical services they provide their patients. The questionnaires completed by 369 doctors, who had graduated from medical school between 1930 and 1964 and who are in active practice, form the basis of this report. More than 50% treat common non-obstetric-gynecologic disorders in their own patients and smaller numbers treat more serious medical conditions. This study confirms a previous one, derived from information obtained from patients, that obstetricians-gynecologists serve as primary physicians to women, not exclusively as specialist-consultants.
