abstract="The National Ambulatory Medical Care Survey (NAMCS) is a sample survey of office-based physicians in the United States conducted by the National Center for Health Statistics, Centers for Disease Control and Prevention. The 1991 sample included 2,540 physicians; 34,183 Patient Record forms were completed. In 1991, there were over 66 million injury-related visits to office-based physicians representing 10% of total visits; this estimate was similar to other sources of data. Injury patients seen in physicians' offices were more likely to be young or middle-aged adults, white, and male. Back symptoms was the most commonly mentioned reason for visit and back sprains was the most frequently recorded diagnosis. The cost of injury-related visits to office-based physicians was estimated to be over $3.5 billion.<p />",
