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. 数据采集工具:使用医院信息系统(HIS/LIS),设计结构化电子病例报告表(eCRF),包含:基线数据、治疗过程、实验室指标、透析器状态、不良事件 2. 数据质量控制双人录入与逻辑校验 采用双人独立录入+第三方核查不一致数据。 盲法评估:安排独立研究人员(非操作护士/医师)评估透析器凝血分级,避免主观偏倚。 校准计划: 实验室设备定期校准(如凝血分析仪每月质控),统一检测方法(如Kt/V采用Daurgidas公式)。 3. 隐私与安全管理 权限分级: 设置数据访问权限(研究者仅可见负责病例,统计员仅可见脱敏数据)。 4. 数据存储与备份 源数据录入至主数据库-医院服务器,每日自动备份至文件夹,每周导出加密备份至离线硬盘 5. 统计分析计划 主要终点:抗凝总有效率(显著+有效)的组间比较(χ2检验) 次要终点: 连续变量(Hb、K?等)采用重复测量方差分析 、透析器凝血等级采用Mann-Whitney U检验 安全性分析:不良事件发生率(Fisher精确检验) 亚组分析:按出血类型(脑出血/消化道出血)分层 6. 应急预案 数据缺失:制定缺失数据处理SOP(如≤5%用多重插补法) 样本量不足:预设延长入组期(最长6个月)或扩大合作中心 7. 伦理合规 -知情同意书明确数据使用范围及保密条款 -建立独立数据监查委员会(DMC)审核严重不良事件

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

1. Data collection tool: Using the Hospital Information System (HIS/LIS), design a structured electronic case report form (eCRF) that includes baseline data, treatment process, laboratory indicators, dialyzer status, and adverse events 2. Data quality control: Two person input and logic verification adopt independent input by two people and third-party verification of inconsistent data. Blind evaluation: Arrange independent researchers (non operating nurses/physicians) to evaluate the coagulation grading of dialyzers to avoid subjective bias. Calibration plan: Regular calibration of laboratory equipment (such as monthly quality control of coagulation analyzers), unified testing methods (such as Daurgidas formula for Kt/V). 3. Privacy and Security Management Permission grading: Set data access permissions (researchers can only see responsible cases, statisticians can only see desensitized data). 4. Data storage and backup Input the source data into the main database - hospital server, automatically backup to a folder daily, and export encrypted backups to an offline hard drive weekly 5. Statistical analysis plan Primary endpoint: Inter group comparison of total anticoagulation efficacy (significant+effective) (chi square test) Secondary endpoints: Continuous variables (Hb, K ?, etc.) were analyzed using repeated measures ANOVA, and dialyzer coagulation grade was tested using Mann Whitney U test Safety analysis: incidence of adverse events (Fisher's exact test) Subgroup analysis: stratified by bleeding type (cerebral hemorrhage/gastrointestinal hemorrhage) 6. Emergency plan Data missing: Develop SOP for handling missing data (such as using multiple imputation method for ≤ 5%) Insufficient sample size: pre-set extension of enrollment period (up to 6 months) or expansion of cooperative centers 7. Ethical compliance -The informed consent form specifies the scope of data use and confidentiality terms -Establish an independent Data Monitoring Committee (DMC) to review serious adverse events
