The goal of this observational study is to analyze the validity of the intracerebral hemorrhage (ICH) Score and a new modified ICH score for the prediction of 12-month functional outcome in patients with primary ICH.

Participants who were admitted to NTUH rehabilitation ward will be followed up to 12 months after the onset of ICH. The follow-up will be conducted by phone interviews.

The ICH Score had been utilized to predict the 30-day mortality after acute intracerebral hemorrhage (ICH), but there's still no reliable tool in predicting the long-term functional outcome in ICH patients. Recently, there have been some studies that use ICH score to predict the prognosis of functional outcome in ICH patients. However, most studies included patients in western societies. Relevant studies in Taiwan were scarce. The present study will follow up the patients with ICH, who were admitted to NTUH rehabilitation ward, up to 12 months post stroke. The follow-up will be conducted by phone interviews at certain time after the onset of ICH. Investigators aim to analyze the validity of the ICH Score for the prediction of 12-month functional outcome in patients with primary ICH. Investigators will also add other variables to see if the revised score could better predict the prognosis among ICH patients.
