Description:Based on findings of the 1977 National Ambulatory Medical Care Survey, this report examines the use of X-rays by office-based physicians. An X-ray is defined as any single or multiple X-ray examination for diagnostic or screening purposes. Radiation therapy is not included. When the phrase X-ray visit appears in these pages, it applies to any office visit where an X-ray was either provided or ordered.
The National Ambulatory Medical Care Survey (NAMCS) is a continuing sample survey conducted annually by the Division of Health Resources Utilization Statistics of the National Center for Health Statistics. The survey-national in range except for Alaska and Hawaii-is designed to explore the provision and utilization of ambulatory care in the offices of non-Federal, office-based physicians. Since the statistics used in this report are based on a sample rather than on the entire universe of office-based physicians, they are estimates only and subject to sampling variability. Along with more information on the survey design and definitions of terms used in NAMCS, the Technical Notes at the end of the report provide guidelines for judging the precision of the estimates presented.
