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. 数据采集:采用纸质CRF表采集数据,确保数据完整性及可追溯性;研究医生完成CRF填写后交由独立录入人员,录入人员在Excel表格中进行统一录入,并随机抽查20%的CRF与原始医疗记录进行比对;炎症因子检测使用成熟试剂盒,由检验科统一检测,以减少检测变异; 2. 数据质量控制: (1)逻辑核查:Excel表格设置各项目的格式,可在录入时实现自动逻辑检查(如超出正常范围等); (2)人工核查:数据管理员每周审核异常值(如检验结果异常、用药记录缺失等); (3)关键变量(如患者术后不良反应、住院时间等)由两名独立人员分别录入并进行比对; 3. 数据储存与安全:原始CRF表存放于科室科研资料储存柜中,由专人保管并上锁;数据录入的Excel表格采用密码加密,每月更换一次密码,并定期进行数据备份。

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

1. Data collection: Data are collected using paper CRF forms to ensure completeness and traceability; after completion by the research physician, CRFs are handed over to independent data entry personnel for uniform entry into Excel spreadsheets, and 20% of CRFs are randomly selected for reconciliation with original medical records; inflammatory factor assays are performed using validated commercial kits and uniformly conducted by the Clinical Laboratory to minimize assay variability; 2. Data quality control: (1)Logical checks: Excel spreadsheets are formatted to enable automated logical validation during data entry (e.g., detection of values outside normal ranges); (2)Manual review: The data manager conducts weekly reviews of outliers (e.g., abnormal laboratory results, missing medication records); (3)Dual data entry for key variables: Critical variables (e.g., postoperative adverse events, length of hospital stay) are entered independently by two personnel, followed by comparison to ensure consistency; 3. Data storage and security: Original CRF forms are stored in a locked research document cabinet within the department, accessible only to designated personnel; Excel files containing entered data are password-protected, with passwords changed monthly, and regular data backups are performed.
