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: ① 由手术医生记录 PTA 操作数据; ② 由具备超声医师资质医生记录术后即刻及随访 MLD; ③ 由透析中心记录透析参数(Qb、压差、Kt/V); ④ 建立电子 CRF 统一格式,确保数据结构化录入。 数据质量控制: ① 双人核对 MLD、通畅时间等关键指标; ② 定期数据稽查(每月一次); ③ 采用唯一化受试者编号避免隐私泄露。 数据管理与安全: ① 数据存储于科内加密服务器; ② 禁止使用移动存储介质; ③ 所有数据更改均留痕记录。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data Collection: (1) PTA procedure data recorded by the operating surgeon; (2) Immediate postoperative and follow-up MLD recorded by the ultrasound physician; (3) The dialysis center will record dialysis parameters (Qb, transmembrane pressure, ); (4) Establish a unified electronic CRF format to ensure structured data entry. Data Quality Control: (1) Two-person verification of key indicators such as MLD and patency time; (2) Regular data audits (once a month); (3) Use unique subject identifiers to avoid privacy breaches. Data management and security: (1) Data are stored on an encrypted departmental server; (2) The use of removable storage media is prohibited; (3) All data modifications shall be recorded with an audit trail. |
