Intracerebral haemorrhage: a model for the prediction of outcome.

The hospital charts and CT scans of 112 patients with spontaneous supratentorial haemorrhage were retrospectively reviewed to evaluate factors important to prognosis. A low Glasgow Coma Scale score, coma, ataxic respiration, abnormal pupils, acute hypertension, large haemorrhage size and intraventricular extension of blood were associated with a poor outcome. Multivariate analysis using the technique of logistic regression identified three variables, the Glasgow Coma Scale score, haemorrhage size and intraventricular extension of blood, which were most predictive of outcome. A model was developed from this analysis which accurately estimates the probability of good outcome and the risk of poor outcome based on data available on presentation. With additional validation, this model may be useful in choosing patients for surgical evacuation of haematomas.
