Abstract

We have analyzed predictors of mortality following closed head injury in a series of 1.031 consecutive patients with closed head injury admitted to hospital from January 1986 through December 1990. All patients were treated in a uniform manner and surgical intervention was performed as soon as possible in patients with intracranial mass lesions. Logistic analysis was used to identify patient and injury characteristics that were independent predictors of mortality within this patient group. Significant predictors were Glasgow Coma Score at admission (p = 0.0000). age (p = 0.0000). bilaterallyunreaclive pupils (p = 0.0000). presence of multiple systemic injuries (p = 0.0004). presence of an intracranial mass lesion (p = 0.0006). and presence of unilateral pupillary abnormalities (p = 0.0279). In an attempt to clarify the relationship between the incidence of these characteristics in series of severely head-injured patients reported during the last 2 decades and the mortality reported in those series, regression analysis was carried out comparing the mean age reported in the series, incidence of mass lesions, and reported mortality. Sixty-four percent of the variability in reported mortality rates could be acounted for by differences in mean age of the patients and mass lesion incidence (p = 0.0035). We conclude that apparent improvements in head injury mortality in the last 2 decades may be partly or wholly due to different population characteristics in the reported series. Multiple injuries appear to be important contributors to patient mortality, and in the interest of improved description of head injury populations, the Injury Severity Score should be reported with age. mass lesion incidence, and Glasgow Coma Score.
