Randomized trial validates a survival prediction model in patients with intracerebral hemorrhage, suggesting improved outcomes with added factors.

To validate and extend a logistic regression model predicting 30-day survival after intracerebral hemorrhage.
Used independent, prospectively collected data for external validation.
Analyzed four factors: Glasgow Coma Scale score, hemorrhage size, pulse pressure, and intraventricular hemorrhage extension.
Assessed additional predictive value of hyperglycemia.
The original model predicted 30-day outcomes for 90% of patients with sensitivity 0.85 and specificity 0.92.
The extended model correctly classified survival status of 94% of patients at 30 days.
A general outcome model achieved a classification accuracy of 95% for death or poor functional status by one year.

Tuhrim et al. (1991) studied this question.
