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:

1 病例报告表/电子数据记录 源数据,是指临床试验中的临床发现、观察和其他活动的原始记录以及其经核准的副本中的所有信息,可以用于临床试验重建和评价。源文件,是指包含源数据的印刷文件、可视文件或者电子文件等。 本临床试验的源数据和源文件包括已签署的知情同意书、有关实验室检验报告、病例记录及其它相关记录等,应保存于各研究中心所在医院的临床试验管理部门。 2 数据管理 研究过程中,需确保临床试验数据的真实性、完整性和私密性。数据管理过程应符合临床试验管理规定,保证临床试验数据的可溯源性。 ①数据库制定和管理:根据CRF表的具体内容,由数据管理人员建立数据管理系统,对数据库访问进行严格的权限设置且账号独立,安排专门人员负责数据库的管理。 ②原始数据监查:CRA 监查试验的进行是否遵循试验方案,确认所有CRF 填写正确完整。如发现错误和遗漏,及时报告研究者改正。修改时需保持原有记录清晰可见,改正需经研究者签名并注明日期。研究者、CRA 及数据管理人员需要对回收的CRF进行核对,确认无误后在CRF 运送单上签字。 ③数据录入与修改:为保证数据的准确性,由两名数据管理员独立进行双份录入并对数据文件进行一致性比对。 对CRF表中存在的疑问,数据管理员将发出疑问表(Data Query),研究者应尽快解答回复,数据管理员根据研究者的回答进行数据确认和修改,必要时可以再次发出疑问表,直到数据疑问清理完毕。 ④数据核查:数据核查方式包括人工核查、计算机化的程序核查。对核查中发现的缺失、异常、逻辑错误等数据问题,数据管理员应及时发出疑问递交研究者解答。 ⑤数据审核与数据库锁定:在临床试验数据录入完成及疑问清理完毕后,由申办者、主要研究者和数据管理、统计师四方共同对数据进行最终的审核,并按照人群集定义进行统计人群划分,确定每个病例归属的分析数据集(包括FAS、PPS、SS)、缺失值的判断及离群值的处理等。 确认数据无误后对数据库进行锁定,数据管理员制定数据库锁定清单,必须满足数据库锁定条件后,由试验相关人员(申办者、主要研究者、统计师、临床项目经理、数据管理员)共同批准数据库锁定,随后导出锁定的数据供统计分析使用。 ⑥数据存档:在临床试验结束后,数据管理部门应将完整的数据库及相关文件移交给申办者,由申办者保存至无该临床操作开展时。

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

Case report form / Electronic data record Source data refers to the original records of clinical findings, observations, and other activities in clinical trials, as well as their approved copies, containing all the information that can be used for the reconstruction and evaluation of the clinical trial. Source files refer to printed, visual, or electronic files that contain the source data. The source data and source files of this clinical trial include signed informed consent forms, relevant laboratory test reports, case records, and other related records, and should be stored in the clinical trial management department of the hospital where each research center is located. 2 Data Management During the research process, it is necessary to ensure the authenticity, completeness, and confidentiality of the clinical trial data. The data management process should comply with the clinical trial management regulations to ensure the traceability of the clinical trial data. 1.Database establishment and management: Based on the specific contents of the CRF form, the data manager establishes a data management system, sets strict access permissions for the database, and assigns a dedicated person to manage the database. 2. Original data monitoring: The CRA monitors whether the trial is conducted in accordance with the trial protocol and confirms that all CRF forms are filled out correctly and completely. If errors and omissions are found, they should be reported to the investigator for correction. When making corrections, the original records should be kept clearly visible, and the corrections should be signed by the investigator and dated. The investigator, CRA, and data manager need to verify the returned CRF forms and sign on the CRF transportation form if there are no errors. 3. Data entry and modification: To ensure the accuracy of the data, two data administrators independently perform double-entry and compare the consistency of the data files. For questions in the CRF form, the data manager will issue a question form (Data Query), and the investigator should reply as soon as possible. The data manager will confirm and modify the data based on the investigator's answer. If necessary, a question form can be issued again until all data questions are cleared. 4. Data verification: Data verification methods include manual verification and computerized program verification. For missing, abnormal, or logical error data problems found during the verification, the data manager should promptly issue a question form for the investigator to answer. 5. Data review and database locking: After the clinical trial data entry is completed and the questions are cleared, the sponsor, principal investigator, data management, and statistician jointly conduct the final review of the data and divide the statistical population according to the population set definition, determine the analysis data set (including FAS, PPS, SS), the judgment of missing values, and the handling of outliers, etc. After confirming that the data is correct, the database is locked, and the data manager prepares a database locking list. Only after meeting the database locking conditions, the database can be locked by the relevant personnel of the trial (sponsor, principal investigator, statistician, clinical project manager, data manager) and then the locked data is exported for statistical analysis use. 6.Data archiving: After the clinical trial is completed, the data management department should transfer the complete database and related files to the sponsor, who will store them until the clinical operation is no longer conducted.
