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: |
本研究的数据采集和管理采用Excel表格与电子数据采集系统(Electronic Data Capture, EDC)相结合的方式,确保数据的完整性、准确性与可追溯性。 1. Excel表格: 研究过程中所有原始数据将首先记录在Excel表格中; 内容包括:患者姓名、扫描部位、关节软骨损伤程度分级; Excel表格由经过培训的研究人员填写,并由两人交叉核对以确保数据准确。 2. 电子采集与管理系统(EDC) 本研究采用ResMan临床试验注册与数据管理公共平台作为EDC系统; 所有Excel表格内数据在核对无误后,将由专人录入EDC系统,系统设有自动逻辑检查功能以控制录入质量; 数据管理负责人定期备份数据,并设置访问权限以保障数据安全; 数据锁定前,所有数据将由研究团队进行统一核查与确认,确保其真实性与可用性。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data collection and management will be performed through a hybrid system combining Excel spreadsheets with an Electronic Data Capture (EDC) platform to guarantee completeness, accuracy, and full traceability. Excel spreadsheets ? All source data will first be recorded in standardized Excel case-report forms. ? Each form contains: patient initials, anatomical region scanned, and grade of articular-cartilage damage. ? Forms are completed by trained study staff and cross-checked by a second reviewer to ensure accuracy. Electronic Data Capture system (EDC) ? ResMan, a public clinical-trial registry and data-management platform, serves as the EDC system. ? After verification, data from the Excel files are entered into ResMan by designated personnel; built-in logic checks automatically flag inconsistencies. ? The data manager performs regular backups and assigns role-based access to safeguard security. ? Before database lock, the entire study team will conduct a unified review and confirmation of all records to ensure authenticity and usability. |
