Abstract
A prognostic model for head injured patients was developed. Patients fall into one of four prognostic categories at the end of the first hospital day: Discharge alive on or before the seventh hospital day. Discharge alive 8–42 days after admission. Discharge alive after 42 days, or dead after five years. Discharge dead before five years. The outcome of 63% of the patients was predicted correctly. The model correctly placed, or missed by only one category, 97% of the patients observed. Errors tended to the optimistic side of observed outcomes. Age and pattern of consciousness were critical prognostic factors.
