共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址):

研究数据将在研究完成后存储于加密数据库。数据不直接公开,但可根据合理的学术研究请求,经课题负责人审批及伦理委员会同意后,以匿名化形式共享。

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

Research data will be stored in an encrypted database upon completion of the study. The data will not be made directly available to the public, but may be shared in anonymised form upon approval by the principal investigator and consent from the ethics committee, following a reasonable request for academic research purposes.

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:

本研究采用 DataWeb 进行病历信息的数据管理,在数据收集之前,由本课题负责人根据研究目的及涉及的变量使用 DataWeb 软件建立资料收集表,数据收集表不应涉及患者姓名、住址、电话等隐私信息,使用受试者编码方式来识别患者代替患者姓名。所有录入数据必须根据病例系统数据如实填写,对于电子病历记载不详细或者未记录变量不填写或者填写“NA”,由两人共同负责资料的收集,其中一人主要负责收集资料的保管及对填写的资料进行检查,防止患者资料泄露并及时发现漏填、误填现象。本课题负责人定期对数据进行核实检查,如遇到有疑惑的问题与数据收集员进行核实,必要时应追溯至病历系统记录数据进行核实。确认数据无疑问后,各方签署数据库锁定申请表,由数据管理员对数据库进行锁定。数据库锁定后,由数据管理员导出分析数据库,交统计人员进行统计分析。锁定后的数据不可再编辑,数据库锁定之后发现的问题,经确认后可在统计分析程序中修正。

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

This study employs DataWeb for the management of medical record data. Prior to data collection, the principal investigator shall utilise DataWeb software to establish data collection forms based on the research objectives and relevant variables. These forms must not include patients' names, addresses, telephone numbers, or other confidential information; instead, patient identification shall be achieved through the use of subject codes. All data entry must accurately reflect the information in the medical record system. Where electronic medical records are insufficiently detailed or variables are unrecorded, these fields shall either remain blank or be marked as ‘NA’. Two individuals shall jointly oversee data collection: one primarily responsible for safeguarding collected materials and verifying completed entries to prevent patient data breaches and promptly identify omissions or errors. The principal investigator shall periodically verify the data. Any queries shall be resolved with the data collector, and where necessary, verified against the electronic medical record system. Upon confirmation of data accuracy, all parties shall sign the database lock request form, after which the data administrator shall lock the database. Following database lockdown, the data administrator exports the analysis database for statistical analysis by the statistician. Locked data cannot be edited; any issues identified post-lockdown may be corrected within the statistical analysis programme after confirmation.
