The National Ambulatory Medical Care Surveys (NAMCS) supply data on ambulatory medical care provided in physicians' offices. The 1985 survey, the tenth in a series of annual surveys, contains information from approximately 2,879 physicians. Data are available on the number of office visits by the patient, the nature and length of the visits, the patient's problem, the physician's diagnosis, and the kinds of diagnostic and therapeutic services rendered. Information is also included on the physician's specialization, type of practice, and geographical location. Demographic information on patients was also collected.

In preparing the data tapes for these collections, the National Center for Health Statistics (NCHS) has removed direct identifiers and characteristics that might lead to identification of data subjects. As an additional precaution, NCHS requires, under section 308(d) of the Public Health Service Act (42 U.S.C. 242m), that data collected by NCHS not be used for any purpose other than statistical analysis and reporting. NCHS further requires that analysts not use the data to learn the identity of any persons or establishments and that the director of NCHS be notified if any identities are inadvertently discovered. ICPSR member institutions and other users ordering data from ICPSR are expected to adhere to these restrictions.
