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:

本研究的数据采集和管理严格遵循《药物临床试验质量管理规范》(GCP)、《医疗器械临床试验质量管理规范》及相关法规,采用 源文件 + 病例记录表 + 电子数据采集系统 的三级架构,确保数据的真实性、完整性、准确性和可溯源性。 一、 病例记录表 定义与作用:病例报告表(CRF)是根据研究方案专门设计的、用于向申办方记录每位受试者全部研究数据的纸质或电子表格。它是将源数据(原始病历)中的关键信息标准化、格式化后转录的载体。 在本研究中的使用: 所有CRF表项的设计均基于本方案(特别是第六、七部分)的观察指标和时点。 研究者或授权的临床研究协调员(CRC)需在受试者每次访视后,及时、准确、完整地将源数据誊录至CRF(如使用纸质版)或作为录入电子系统的直接依据。 CRF的任何修改必须留有痕迹,并注明日期和原因。 二、 电子数据采集和管理系统 系统类型:本研究将采用经过验证的、基于互联网的电子数据采集系统进行中心化数据管理。系统功能符合 FDA 21 CFR Part 11 等对电子记录和电子签名的规范要求。 核心流程: 数据录入:经授权的CRC或研究人员,依据源文件和CRF,将数据直接在线录入EDC系统。 逻辑核查:EDC系统内置预设的逻辑核查程序,在数据录入时或录入后自动进行实时检查,对数据的范围、逻辑一致性(如访视日期顺序、异常值)即时发出疑问。 质疑管理:所有系统或人工发现的疑问,均通过EDC系统生成电子质疑,发送至研究中心。研究者必须在系统中基于源数据进行核对、答复或修正。全过程留有审计痕迹。 源数据核查:临床研究监查员定期访问研究中心,在EDC系统中核对已录入数据与原始源文件的一致性,确保数据质量。 数据锁定:在所有受试者完成试验、数据录入完毕且所有疑问关闭后,由主要研究者、数据管理员和生物统计师共同审核并执行最终的数据库锁定。锁定后数据用于统计分析。 三、 数据安全与保密 所有数据通过受试者唯一识别码进行标识,去除了直接的个人身份信息。 EDC系统实行严格的角色权限控制,确保数据仅被授权人员访问。 所有电子操作均留有不可删除的审计日志。 最终的研究数据将按规定长期存档,保存至临床试验结束后至少10年。

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

Data Collection and Management The data collection and management for this study strictly adhere to the Good Clinical Practice (GCP), Good Clinical Practice for Medical Device Clinical Trials, and relevant regulations. A three-tiered architecture of Source Documents + Case Report Form (CRF) + Electronic Data Capture (EDC) System is employed to ensure the authenticity, integrity, accuracy, and traceability of the data. I. Case Report Form (CRF) Definition and Purpose: The Case Report Form (CRF) is a paper-based or electronic form specifically designed according to the study protocol to record all research data for each subject for the sponsor. It serves as the vehicle for transcribing, standardizing, and formatting key information from the source data (original medical records). Usage in This Study: The design of all CRF items is based on the observation indicators and time points specified in this protocol (particularly in Sections VI and VII). Investigators or authorized Clinical Research Coordinators (CRCs) must transcribe the source data into the CRF (if using a paper version) in a timely, accurate, and complete manner after each subject visit, or use it as the direct basis for data entry into the electronic system. Any modifications to the CRF must leave an audit trail, clearly noting the date and reason for the change. II. Electronic Data Capture and Management System System Type: This study will utilize a validated, internet-based Electronic Data Capture (EDC) system for centralized data management. The system's functionality complies with standards for electronic records and electronic signatures, such as FDA 21 CFR Part 11. Core Process: Data Entry: Authorized CRCs or research personnel directly enter data online into the EDC system, based on source documents and the CRF. Logical Checks: The EDC system has built-in, pre-programmed logic check procedures that automatically perform real-time validation during or after data entry. It immediately raises queries regarding data range, logical consistency (e.g., visit date sequence, outliers), etc. Query Management: All queries identified by the system or manually are generated as electronic queries within the EDC system and sent to the research site. Investigators must review, respond to, or correct these queries within the system based on the source data. The entire process maintains a complete audit trail. Source Data Verification (SDV): Clinical Research Associates (Monitors) periodically visit the research site to verify the consistency between the data entered in the EDC system and the original source documents, ensuring data quality. Database Lock: After all subjects have completed the trial, all data has been entered, and all queries have been resolved, the Principal Investigator, Data Manager, and Biostatistician jointly review and authorize the final database lock. The locked database is then used for statistical analysis. III. Data Security and Confidentiality All data is identified using a unique subject identification code, with direct personal identifiers removed. The EDC system implements strict role-based access controls to ensure data is accessible only to authorized personnel. All electronic operations leave an indelible audit log. The final research data will be archived in accordance with regulations for long-term storage, for a minimum of 10 years after the completion of the clinical trial.
