Retrospective Cohort Study of Intracerebral Hemorrhage

Study Overview
=================
Brief Summary
-----------------
The investigators design a retrospective, observational cohort study to provide contemporary information on the prevalence, characteristics, risk stratification，cost-effective, treatments and prognosis of Chinese hospitalized adult patients with intracerebral hemorrhage.

Detailed Description
-----------------
Intracerebral hemorrhage (ICH) remains a devastating disease with high mortality, yet few therapeutic managements have been proved effective. Large quantities of work needs to be done to fully delineate the prevalence and prognosis of ICH. Hence, the investigators design a prospective, observational cohort study to provide contemporary information on the prevalence, characteristics, risk stratification，cost-effective, treatments and prognosis of Chinese hospitalised adult patients with ICH.
