BACKGROUND AND PURPOSE
Epidemiological studies of intracerebral hemorrhage (ICH) have consistently demonstrated variation in incidence, location, age at presentation, and outcomes among non-Hispanic white, black, and Hispanic populations. We report here the design and methods for this large, prospective, multi-center case-control study of ICH.
METHODS
The Ethnic/Racial Variations of Intracerebral Hemorrhage (ERICH) study is a multi-center, prospective case-control study of ICH. Cases are identified by hot-pursuit and enrolled using standard phenotype and risk factor information and include neuroimaging and blood sample collection. Controls are centrally identified by random digit dialing to match cases by age (±5 years), race, ethnicity, sex, and metropolitan region.
RESULTS
As of March 22, 2013, 1655 cases of ICH had been recruited into the study, which is 101.5% of the target for that date, and 851 controls had been recruited, which is 67.2% of the target for that date (1267 controls) for a total of 2506 subjects, which is 86.5% of the target for that date (2897 subjects). Of the 1655 cases enrolled, 1640 cases had the case interview entered into the database, of which 628 (38%) were non-Hispanic black, 458 (28%) were non-Hispanic white, and 554 (34%) were Hispanic. Of the 1197 cases with imaging submitted, 876 (73.2%) had a 24 hour follow-up CT available. In addition to CT imaging, 607 cases have had MRI evaluation.
CONCLUSIONS
The ERICH study is a large, case-control study of ICH with particular emphasis on recruitment of minority populations for the identification of genetic and epidemiological risk factors for ICH and outcomes after ICH.
背景与目的
脑出血（ICH）的流行病学研究表明，非西班牙裔白种人、黑人和西班牙裔人群的发病率、位置、发病年龄和预后存在差异。我们在此报告这项针对 ICH 的大型、前瞻性、多中心病例对照研究的设计和方法。
方法
种族/民族脑出血差异研究（ERICH）是一项针对 ICH 的多中心前瞻性病例对照研究。通过热线追踪识别病例，并使用标准表型和危险因素信息进行入组，包括神经影像学和血液样本采集。通过随机数字拨号中心识别对照，以年龄（±5 岁）、种族、民族、性别和大都市区域与病例匹配。
结果
截至 2013 年 3 月 22 日，已有 1655 例 ICH 病例被招募到研究中，达到了该日期目标的 101.5%，已招募 851 例对照，达到了该日期目标的 67.2%（1267 例对照），共计 2506 例受试者，达到了该日期目标的 86.5%（2897 例受试者）。在入组的 1655 例病例中，有 1640 例病例的病例访谈已输入数据库，其中 628 例（38%）为非西班牙裔黑人，458 例（28%）为非西班牙裔白人，554 例（34%）为西班牙裔。在提交的 1197 例影像学检查中，有 876 例（73.2%）有 24 小时随访 CT 可用。除 CT 成像外，还有 607 例进行了 MRI 评估。
结论
ERICH 研究是一项针对 ICH 的大型病例对照研究，特别强调招募少数族裔人群，以确定 ICH 的遗传和流行病学风险因素以及 ICH 后的结局。
