Survey of the Incidence, Prevalence, and Costs of Head and Spinal Cord Injury

摘要

A major health survey, requiring use of probability sampling, was designed and conducted to determine the magnitude of the problem of head and spinal cord injury for the population of the contiguous United States. This survey provided estimates of the incidence, prevalence, and economic costs of that type of injury for the year 1974. Also provided were estimates for subpopulations defined by demographic variables (age, race, sex, and region in which injury occurred), as well as related estimates on cause of injury, length of stay in hospital, and mortality. This report is intended as a background document. It contains a detailed description of the multistage sampling design, the criteria for eligibility for the survey, and the methodology for collecting, processing, and analyzing the data. For published findings of the survey, refer to 'Report on the National Head and Spinal Cord Injury Survey', which appeared as a supplement to the Journal of Neurosurgery in November, 1980.
