The Influencing Factors and Prediction Model of Poor Prognosis of Spontaneous Intraparenchymal Hemorrhage

Study Overview
=================
Brief Summary
-----------------
This study was designed to explore the influencing factors of spontaneous intraparenchymal hemorrhage's prognosis and develop predictive models for poor prognosis by establishing a cohort of spontaneous intraparenchymal hemorrhage (including both of the supratentorial intracerebral hemorrhage and cerebellar hemorrhage), and analyzing the correlation between collected variables and patients' outcomes.

Detailed Description
-----------------
Spontaneous intracranial hemorrhage is an important type of cerebrovascular disease. The disease has an acute onset, a serious condition, and a high mortality rate. Besides, the survivors always live with severe neurological dysfunction. It is essential to determine the influencing factors of poor prognosis, estimate patient's condition and predict the prognosis timely. This study consists of two parts. The first part establishes a cohort of spontaneous intraparenchymal hemorrhage (including both of the supratentorial intracerebral hemorrhage and cerebellar hemorrhage), and analyzes the influence of different factors, such as surgical methods, on the prognosis. In the second part, a nested case-control study nested in this cohort will be established to analyse the influence of some other factors. The biological specimens are tested. The collected data were analysed to find out the risk factors of poor prognosis and establish a predictive model. Recruitment and follow-up of the participants is expected to continue after the initial goal is achieved. As a large sample database of intracranial hemorrhage, this cohort will provide more research data for the future exploration of more clinical problems.
