Epidemiologic predictors of 30-day survival in cerebellar hemorrhage.
BACKGROUND
Outcome after cerebellar hemorrhage is relatively poorly understood.


OBJECTIVE
To describe cerebellar hemorrhage and to establish if there were epidemiologic risk factors associated with early mortality.


METHODS
Computerized records were searched to identify intracerebral hemorrhage (ICD-9-CM code 431) from 1986 to 1996 at 2 hospitals. Charts were abstracted using a standardized protocol. The provincial vital statistics registry was used to confirm mortality data. A multivariable logistic regression model was developed to identify predictors of 30-day mortality.


RESULTS
Of 629 identified cases of intracerebral hemorrhage, 79 (12.5%) were cerebellar. The 30-day mortality was 41.7%. Approximately one third (31.7%) had an identifiable underlying cause. The odds of survival at 30 days was significantly reduced (odds ratio = 0.24; 95% confidence interval, 0.08 to 0.74) if the hemorrhage was caused by an identifiable underlying cause.


CONCLUSIONS
Cerebellar hemorrhage with an underlying cause is more likely to be fatal than idiopathic or hypertensive cerebellar hemorrhage.
