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: |
研究将建立详细的数据收集协议,包括标准化的测量方法、仪器型号和测量时间点等指导规范。所有数据将通过规范设计的病例记录表(CRF)进行采集,包括受试者基本信息、临床检查结果和随访数据。研究开始前将对所有研究人员进行统一培训,确保其充分理解并严格遵守数据收集协议和CRF填写规范。 研究将组建专门的质量控制团队,负责监督整个数据收集和处理过程。团队成员将定期审核CRF和数据库,确保数据的准确性和一致性。采用双重数据输入或独立校验机制以减少录入错误,并设立数据清洗程序,及时识别和纠正异常或不一致的数据。 同时建立严格的数据安全措施,包括数据存储、备份和访问控制,以确保数据的机密性和完整性。对所有测量仪器进行定期校准和维护,并详细记录校准维护过程,以确保测量结果的可靠性。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
A detailed data collection protocol will be established, including standardized measurement methods, equipment specifications, and measurement time points. All data will be collected through standardized Case Report Forms (CRFs), including subjects' basic information, clinical examination results, and follow-up data. Before the study begins, all research personnel will receive unified training to ensure their full understanding and strict adherence to the data collection protocol and CRF completion guidelines. A dedicated quality control team will be established to oversee the entire data collection and processing. Team members will regularly review CRFs and databases to ensure data accuracy and consistency. Double data entry or independent verification mechanisms will be implemented to reduce entry errors, and data cleaning procedures will be established to identify and correct anomalous or inconsistent data promptly. Strict data security measures will be implemented, including data storage, backup, and access control, to ensure data confidentiality and integrity. All measuring instruments will undergo regular calibration and maintenance, with detailed records of these processes maintained to ensure the reliability of measurement results. |
