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:

数据采集阶段: 1.人员培训与考核:调查员需接受统一培训,通过模拟调查或考核确保操作一致性。 2.现场监督与复核:设立督导员抽查10%~20%的调查对象,复核数据真实性(如电话回访、重复测量)。 3.仪器与试剂标准化:校准测量设备(如血压计、实验室仪器),统一试剂批次。 数据管理与分析阶段: 1.数据录入:双人独立录入,比对不一致数据(用EpiData软件的逻辑校验),清理异常值。 2.偏倚控制:分析阶段校正混杂因素,评估无应答偏倚。

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

Data Collection Phase: 1. Personnel Training and Assessment: Investigators were subjected to uniform training, and operational consistency was ensured through simulated surveys or assessments. 2. On-Site Supervision and Verification: Supervisors were assigned to randomly verify 10%–20% of the surveyed subjects to confirm data authenticity (e.g., via telephone follow-ups or repeated measurements). 3. Standardization of Instruments and Reagents: Measurement devices (e.g., sphygmomanometers and laboratory instruments) were calibrated, and reagent batches were standardized. Data Management and Analysis Phase: 1. Data Entry: Dual independent data entry was performed, with discrepancies resolved through cross-verification (using EpiData software for logical validation), followed by outlier removal. 2. Bias Control: Confounding factors were adjusted during the analysis phase, and non-response bias was evaluated.
