Han et al reported a nomogram for predicting death within 2 days of an intracerebral hemorrhage (ICH). These can help to identify a high-risk patient who may require more aggressive management. The authors are from North China University of Science and Technology Affiliated Hospital in China.
Patient selection: adult (age > 18 years) with intracerebral hemorrhage
Outcome: death within 2 days of the stroke
Parameters:
(1) Glasgow coma scale (GCS)
(2) intraventricular hemorrhage
(3) brain stem hemorrhage (BSH)
(4) volume of the hematoma, from 0 to 200
points for hematoma volume =
= 0.5 * (volume)

Interpretation:
• minimum score: 0
• maximum score: 282.3
value of X =

probability of 2-day mortality =
= 1 / (1 + EXP((-1) * X))
