Immediate prognosis of primary intracerebral hemorrhage using an easy model for the prediction of survival.

We reviewed the medical records and CT scans of 138 patients hospitalized for spontaneous supratentorial hemorrhage and conservatively treated. Seventeen clinico-anamnestic variables and five CT desumed findings were collected. Using univariate analysis we found eight significant predictors of 30-day mortality: intraventricular spread (IVS) of blood, volume of the hemorrhage, Glasgow Coma Scale (GCS) score, midline shift, hyperglycemia, pupillary abnormalities, limb paresis and gaze deviation. With multivariate logistic regression analysis we found three independent predictors of 30-day mortality: IVS of blood, volume of the hemorrhage and GCS score. Using these three independent variables we developed an easy model which allows an immediate estimate of the probability of survival with a high degree of sensitivity and specificity.
