The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):
|
CRF table was used to share the original data, and the original data was shared after the clinical study

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)研究资料报告表:每个入选病例都必须完成研究资料报告表。为保证原始资料的客观性和下一步数据处理工作的质量,在原始观察表的等录时,课题组制订了原则:明显错误处用红笔改过,并在旁边签名并标明日期;生存质量量表多个选择项目的单项选择条目,如相邻两个选项均被选中,随机取其中1个;若选中不相邻的两或多项,首先查阅病例,无法查实者,按缺失值处理(美国波士顿健康研究所量表数据处理原则)。
(2)建立数据库:数据分别独立进行双人录入,数据核查,随机抽取10%的研究资料报告表人工检查。统计人员进行盲态审核后进行数据锁定。在此期间,将有疑问表通过临床监查员转交研究者进行数据审核,研究者应尽快回答并返回。随机抽取10%的研究资料报告表人工检查一遍,考察是否存在数据出错。完成后由统计人员再对数据进行盲态审核,确认所建立的数据库正确后,由主要负责人、数据管理人员和统计分析人员对数据库进行锁定。锁定的数据文件不允许再做变动。
(3)数据处理:在数据锁定后,由负责单位和统计学专家按统计计划书要求进行统计分析。
课题负责单位和各分中心研究单位者应同意分别保存所有研究资料。包括对所有参加受试者的确认(能有效核对不同的记录资料,如研究资料报告表和医院原始记录)、所有原始的有签名患者知情同意书、所有研究资料报告表等。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:
|
(1) Research data report form: each selected case must complete the research data report form. In order to ensure the objectivity of the original data and the quality of the next step of data processing, the research group formulated the following principles when recording the original observation table: correct the obvious errors with red pen, sign and mark the date beside; if the single choice item of multiple choice items in the quality of life scale is selected, if the adjacent two options are selected, one of them will be selected randomly; if the two or two that are not adjacent are selected If there are more than one item, the case should be consulted first, and those who cannot be verified will be treated as missing value (Boston Institute of health scale data processing principle).
(2) Establishment of database: data were independently input by two persons, data verification, randomly selected 10% of the research data report forms for manual inspection. Statistical personnel will lock the data after blind audit. During this period, the question form will be transferred to the researcher for data review through the clinical monitor, and the researcher should answer and return as soon as possible. Randomly select 10% of the research data report forms and check them manually to see if there is any data error. After completion, the statisticians will conduct blind audit on the data, and after confirming that the established database is correct, the main person in charge, data management personnel and statistical analysis personnel will lock the database. The locked data file is not allowed to be changed.
(3) Data processing: after the data is locked, the responsible unit and statistical experts conduct statistical analysis according to the requirements of the statistical plan.
The research units in charge of the project and the research units of each sub center shall agree to keep all research data separately. It includes the confirmation of all participants (able to effectively check different records, such as the research data report form and the original hospital records), all original signed informed consent forms of patients, all research data report forms, etc
