Headache as the Reason for Office Visits, National Ambulatory Medical Care Survey: United States, 1977-78

摘要

Headache was the principal cause of an estimated 18,341,923 visits to office-based physicians during 1977-78. Headache was the seventh most frequent symptomatic reason for visits given by patients. The estimates in this report are based on data collected in the National Ambulatory Medical Care Survey (NAMCS), a probability sample survey conducted yearly by the Division of Health Care Statistics of the National Center for Health Statistics. Since the estimates presented in this report are based on a sample rather than on the entire universe of office-based physicians, the data are subject to sampling variability.
