Clinical Outcomes Research Initiative

The Clinical Outcomes Research Initiative (CORI) was established in 1995 under the American Society for Gastrointestinal Endoscopy (ASGE) to study outcomes of gastrointestinal (GI) endoscopic procedures in clinical settings. Physicians participating in the CORI consortium produce GI endoscopy reports using an electronic health record developed specially for the project. CORI practice sites include hospitals, ambulatory care centers, private practices, universities, and Veteran's hospitals. The practice data are stripped of most patient and physician identifiers before transmitting to a central data repository, where they are tested for completeness and accuracy. Data from all participating practices are merged and stored in the National Endoscopic Database (NED).

Data from the NED has been analyzed to examine endoscopic practice patterns, including endoscopic utilization, frequency and severity of endoscopic findings, and endoscopic treatment and medical management. The data also serve as a resource to develop research hypotheses and to support quality measure reporting. CORI data has already been utilized to support many research initiatives, many of which have resulted in publications in medical journals and presentations at GI conferences.

In addition to availability in through the CORI consortium, the data collected in the NED since 2000 is been contributed to the NIDDK Repository and is available for request through the NIDDK Repository site.

The current data package contains data from the v3 warehouse from 2000 through 2010.

临床结局研究倡议（Clinical Outcomes Research Initiative, CORI）于1995年在美国胃肠内镜学会（American Society for Gastrointestinal Endoscopy, ASGE）框架下成立，旨在探究临床场景中胃肠（gastrointestinal, GI）内镜操作的临床结局。参与CORI联盟的医师需使用专为该项目开发的电子健康记录系统撰写胃肠内镜检查报告。CORI的实践站点涵盖医院、门诊护理中心、私人诊所、高校以及退伍军人医院。在将数据传输至中央数据存储库前，会移除绝大多数患者与医师的识别信息，随后在该存储库中对数据的完整性与准确性进行校验。所有参与机构提交的实践数据将被整合并存储于国家内镜数据库（National Endoscopic Database, NED）。

针对国家内镜数据库的数据已开展多维度分析，以探究内镜实践模式，包括内镜检查使用率、内镜检出异常的发生频率与严重程度，以及内镜治疗与内科管理方案。该数据同时可作为研发研究假说、支持质量指标报告的核心资源。CORI数据已被用于支撑多项研究项目，其中不少成果已发表于医学期刊，并在胃肠病学相关会议上进行展示。

除可通过CORI联盟获取该数据外，2000年起收录于国家内镜数据库的相关数据已提交至美国国家糖尿病、消化和肾脏疾病研究所（National Institute of Diabetes and Digestive and Kidney Diseases, NIDDK）数据存储库，用户可通过该存储库官方网站申请获取。

当前数据包包含2000年至2010年期间v3数据仓库中的全部数据。
