Abstract:

Study examining demographic and injury factors associated with hospital charges for persons with new spinal cord injury (SCI). The objectives were (1) to describe the distribution of charges, (2) to determine which demographic and injury characteristics are associated with charge outlier status, and (3) to identify a model that uses demographic and injury characteristics to predict charge outlier status. Data was analyzed for 13,392 patients admitted to 24 acute, intensive, interdisciplinary rehabilitation settings after traumatic SCI between November 1972 and August 1986. Statistically significant results were found between SCI charge outliers and non-outliers based on ethnicity, education, employment, level of injury, American Spinal Injury Association (ASIA) impairment classification, and sponsor of hospitalization (government insurance, private insurance, worker's compensation, or self-pay). A model for the prediction of SCI charge outlier status was defined.
