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:

(一)数据收集阶段 1.明确定义研究中所有变量的测量方法、样本采集时间节点、标化记录格式与单位。 2.使用标准化、易执行的CRF电子表格便于数据收集。 (二)数据录入与存储 1.主要终点、不良事件等关键数据由2名研究人员独立录入,不一致时追溯原始记录。 2.采用盲态数据输入法,使用中性标签代替真实分组;对敏感性信息去标识化。 3.如实记录修改数据时间、修改人员以及原因。 (三)数据质量控制 1.逻辑核查:对于不符合预设逻辑的变量结果实时核查是否有误,并及时更正。 2.盲态数据核查:数据分析者在结题前保持盲态。 (四)缺失数据处理 1.预防措施:设计阶段简化变量数量,关键变量设为必填项;实施阶段设置自动提醒(如每日短信提醒研究者填写未完成数据)。关键变量缺失时,启动72小时溯源流程。 2.统计方法:采用多重插补(Multiple Imputation),通过R包library(mice)实现。

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

(I) Data Collection Phase 1. Clearly define measurement methods for all study variables, sample collection timepoints, standardized recording formats, and units. 2. Implement electronic Case Report Forms (CRFs) with standardized and user-friendly templates to facilitate data collection. (II) Data Entry & Storage 1. Dual-entry verification: Key data (e.g., primary endpoints, adverse events) are independently entered by two researchers. Discrepancies trigger reconciliation with source documents. 2. Blinded data entry: Use neutral labels to mask group allocation; de-identify sensitive information. 3. Audit trail: Document all data modifications with timestamps, responsible personnel, and justifications. (III) Data Quality Control 1. Logic checks: Flag variables violating predefined logical rules for real-time validation and correction. 2. Blinding integrity: Maintain blinding of data analysts until study completion. (IV) Handling Missing Data 1. Preventive measures: 1) Design phase: Minimize variables; designate key variables as mandatory fields. 2)Implementation phase: Enable automated reminders (e.g., daily SMS alerts for incomplete entries). Initiate 72-hour source data verification for missing key variables. 2. Statistical methods: Apply Multiple Imputation using the R package mice (Multivariate Imputation by Chained Equations).
