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:

本研究的数据收集与管理将严格按照标准化流程执行,确保数据的真实性、完整性与安全性。数据采集主要通过两种途径进行:一是回顾性临床数据,由经过培训的专职研究人员从医院电子病历系统中提取,提取内容涵盖人口学特征、诊断、治疗及结局等关键变量;二是前瞻性数据,采用统一设计的电子或纸质病例报告表(CRF)及结构化问卷进行收集,由研究人员在随访时点现场或远程录入。 数据记录与审核过程实行分级质量控制。所有采集的数据需由录入人员初步核对,随后提交至医院科研外事科或指定质控部门进行二次审核,审核内容包括数据的逻辑性、完整性与合规性。审核中发现的问题将及时反馈并修正,确保数据准确可靠。数据传输均通过医院内部安全网络或加密移动存储设备进行,严禁通过公共网络传输原始数据。 在数据管理与隐私保护方面,所有收集的数据均进行脱敏处理,删除或替换可直接识别患者身份的信息。数据以编码形式存储于专用研究数据库,实行专人专机管理,并定期备份。纸质材料锁存于专用文件柜。整个研究过程严格遵守《个人信息保护法》及相关伦理规范,确保患者隐私不受泄露。

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

The data collection and management in this study will be strictly executed following standardized procedures to ensure the authenticity, integrity, and security of the data. Data will be acquired through two primary pathways: first, retrospective clinical data will be extracted from the hospital's electronic medical record system by trained dedicated research personnel, covering key variables such as demographic characteristics, diagnoses, treatments, and outcomes; second, prospective data will be collected using uniformly designed electronic or paper-based case report forms (CRFs) and structured questionnaires, which will be entered on-site or remotely by researchers at follow-up time points.A multi-tiered quality control process will be implemented for data recording and review. All collected data must undergo an initial verification by the entry personnel before being submitted to the hospital's Department of Scientific Research and Foreign Affairs or a designated quality control unit for a secondary audit. This audit will examine the data for logical consistency, completeness, and compliance. Any issues identified during the audit will be promptly communicated and rectified to ensure data accuracy and reliability. All data transfers will be conducted via the hospital's secure internal network or encrypted removable storage devices. The transmission of original data through public networks is strictly prohibited.Regarding data management and privacy protection, all collected data will be de-identified by removing or replacing information that could directly identify patients. The data will be stored in a coded format within a dedicated research database, managed under a principle of dedicated personnel and computers, and backed up regularly. Any paper-based materials will be securely locked in dedicated filing cabinets. The entire research process will strictly adhere to the Personal Information Protection Law and relevant ethical guidelines to ensure that patient privacy is not compromised.
