About this study
Official title: A Retrospective Observational Cohort Study in Chinese Patients With Primary Intracerebral Hemorrhage
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.
Read the 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.

absolute peripheral hematoma edema growth in CT/MRI measured by picture archiving and communication systems(PACS) system
absolute peripheral hematoma edema growth in CT/MRI measured by PACS system
Measured: 2-3years
Relative peripheral hematoma edema(rPHE)
absolute PHE divided by hematoma volume in CT/MRI
Measured: 2-3years
National institute of health stroke scale（NIHSS score）
NIHSS 0-42, higher indicate worse outcome

Who may be eligible to take part?
The sponsor lists 1 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 17 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Feng Gao, MD,PhD (13588451471, 2202012@zju.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
proportion of patients with a 3-month modified Rankin Scale (mRS) score≤ 3 proportion of patients with a 3-month modified Rankin Scale (mRS) score≤ 3 proportion of patients with a 3-month modified Rankin Scale (mRS) score≤ 3 (time frame: 2-3years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04803292, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Mar 2021.
