数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

本项目运用电子化数据捕捉系统(EDC),由数据管理团队依据研究方案和病例情况,构建电子病例报告表(eCRF)。数据管理团队基于项目主管、研究者、CRC、监督员、稽查员等职责分配,赋予他们不同的访问账号和操作权限,以便进入EDC系统。研究助理需在不同观察阶段,及时且精确地将病例数据远程输入到eCRF平台中;eCRF并非原始数据载体,其上的信息直接来源于“研究病例”。 监督和稽查人员可以通过EDC系统进行数据监控,如发现数据问题,可立即在线标注并提问,研究者或助理应在线解答并对错误数据进行修正。每份患者观察资料经临床研究助理(CRA)校对确认无误后,数据管理员将对数据进行封锁处理,直至所有患者数据均被锁定。 锁定全部数据之后,数据管理员按照统计需求,将数据汇入预定格式的数据库,并由统计人员执行后续的数据分析工作。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

This study utilizes an Electronic Data Capture (EDC) system. The data management team developed electronic Case Report Forms (eCRFs) in strict alignment with the study protocol and case-specific clinical parameters. Access credentials and operational privileges within the EDC system were assigned differentially to stakeholdersincluding the project director investigators clinical research coordinators (CRCs) monitors and auditorsbased on their predefined roles and responsibilities. Research associates are required to remotely input patient data into the eCRF platform accurately and promptly at each observational timepoint. The eCRF does not serve as the original data repository; all entries must be directly sourced from verified source documents (e.g. hospital records diagnostic reports). Monitors and auditors perform real-time data surveillance via the EDC system. Identified discrepancies are flagged electronically through annotated queries which investigators or associates must resolve online with appropriate corrections. Following verification by clinical research associates (CRAs) to ensure data integrity the data manager implements a database lock for each patients dataset. Final database lock is executed only after all participant records are validated. Post-lock the data manager exports the dataset into a pre-specified format compliant with CDISC SDTM standards. Statisticians subsequently conduct analyses per the Statistical Analysis Plan (SAP).
