Summary:

The National Ambulatory Medical Care Surveys (NAMCS) supply data on ambulatory medical care provided in physicians' offices. The 1993 survey contains information from 35,978 patient visits to 1,802 physicians' offices. Data are available on the patient's smoking habits, reason for the visit, expected source of payment, the physician's diagnosis, medications ordered, and the kinds of diagnostic and therapeutic services rendered. Information is included on the physician's specialization and geographic location. The file also supplies drug mentions data, such as medication code, generic name and code, brand name, entry status, prescription status, federal controlled substance status, composition status, and related ingredient codes. Demographic information on patients, such as age, sex, race, and ethnicity, was also collected.
