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:

本研究采用纸质病例报告表(CRF)收集数据,后续通过电子录入方式建立研究数据库。数据管理员根据研究方案要求设计标准化的纸质 CRF,确保表 格逻辑清晰、易于填写,包含所有研究变量的规范录入格式。研究者或临床研 究协调员负责在纸质 CRF 上及时、真实、完整地记录每位研究参与者在研究中 的所有相关资料,确保字迹清晰、信息准确。 数据录入采用双人独立录入模式,由经过专门培训的数据录入员根据纸质 CRF 进行数据录入,两人独立完成后进行一致性核查,对不一致的数据项进行 核实和纠正。数据管理员建立标准化的质量控制程序,通过数据库查询或统计 软件脚本定期执行质量检查,重点关注数据完整性、逻辑一致性、异常值识别 和缺失数据模式分析。 当发现数据问题时,数据管理员生成标准化的数据疑问表,详细列出需要 澄清的问题,包括日期逻辑性、入组排除标准一致性、数值范围合理性、缺失 数据等关键问题。研究者收到疑问表后进行书面解答并签名确认,数据录入员 根据研究者的答疑结果进行相应的数据修改和录入。整个疑问处理过程建立完 整的书面记录,包括疑问内容、解答过程和最终处理结果,确保数据修改的可 追溯性。 所有数据疑问解决后,数据管理人员对数据进行最终清理,生成"清洁"数 据集和数据质量报告。随后组织数据审核会议,由主要研究者、统计分析人员、 数据管理人员和质量控制人员共同参与,全面审核数据收集完整性、主要变量质量、缺失数据影响,并对异常值处理做出决策。各方代表在充分讨论基础上 签署数据审核决议,确认数据质量符合统计分析要求。 数据审核通过后,数据管理人员执行数据库锁定程序,建立最终分析数据 集的版本控制记录,并将锁定数据提交统计分析团队。纸质 CRF 作为原始资料 妥善保存,建立完整的文档管理体系,包括数据收集表、疑问处理记录、数据 修改日志等。数据库锁定后如需进行任何数据变更,必须有充分的科学依据, 经主要研究者、统计学家和数据管理员共同签署同意书后方可执行,并详细记 录变更的完整过程。 研究建立严格的数据安全保密措施,限制数据访问权限,对涉及个人身份 信息的数据进行去标识化处理,建立定期数据备份机制,确保纸质资料和电子 数据的安全存储。同时制定数据使用协议和保密承诺,明确数据使用范围和责 任人员,保障研究研究参与者的隐私权益。

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

In this study, paper case report form (CRF) was used to collect data, and the research database was established by electronic entry. Data managers designed standardized paper CRFS according to the study protocol requirements, ensuring that the grid was logically clear, easy to fill out, and contained standardized entry formats for all study variables. The investigator or clinical research coordinator is responsible for recording all relevant data of each study participant in the study on the paper CRF in a timely, true and complete manner, ensuring clear handwriting and accurate information. Two independent data entry modes were used, and specially trained data entry staff entered the data according to the paper CRF. After the two independently completed the data entry, the consistency check was conducted to verify and correct the inconsistent data items. Data managers establish standardized quality control procedures and perform regular quality checks through database queries or statistical software scripts, focusing on data integrity, logical consistency, outlier identification, and analysis of missing data patterns. When data problems were identified, a standardized data query form was generated by the data manager to list in detail the issues that needed clarification, including key issues such as date logic, consistency of inclusion and exclusion criteria, rationality of numerical ranges, and missing data. After receiving the question form, the researcher answered the question in writing and signed the form. The data entry clerk modified and entered the corresponding data according to the results of the researcher's answer. A complete written record of the whole question processing process was established, including the question content, the solution process and the final processing results to ensure the traceability of data modification. After all data queries were resolved, data managers performed a final cleaning of the data to generate a "clean" data set and a data quality report. Subsequently, a data review meeting was organized in which the principal investigators, statistical analysts, data managers, and quality control personnel participated to comprehensively review the completeness of data collection, the quality of key variables, the impact of missing data, and to make decisions regarding the handling of outliers. Representatives of all parties signed the data review resolution on the basis of full discussion, confirming that the data quality met the requirements for statistical analysis. After data review was approved, data managers performed database locking procedures, established version-control records for the final analysis data set, and submitted the locked data to the statistical analysis team. Paper CRFS were properly stored as original data, and a complete document management system was established, including data collection forms, query processing records, data modification logs, etc. Any changes to the data after the database lock must be based on scientific evidence, signed consent forms by the principal investigator, statistician, and data manager, and the complete process of the changes should be recorded in detail. To establish strict data security and confidentiality measures, restrict data access rights, de-identify data involving personal identity information, establish a regular data backup mechanism, and ensure the safe storage of paper materials and electronic data. At the same time, a data use agreement and confidentiality commitment were formulated to clarify the scope of data use and responsible personnel, and to protect the privacy rights of research participants.
