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: 广东医科大学附属医院临床研究课题申请书研究者根据受试者的原始观察记录,将数据及时、完整、正确、清晰地载入病例报告表。经过监察员审核、签字后的调查表应及时送交临床研究数据管理员。他们之间的各种疑问及解答的交换应当采用疑问表形式,疑问表应保存备查。病例报告表(CRF)用以记录每一名受试者在试验过程中的数据。因此,CRF必须清晰完整,要用黑色签字笔填写。数据及用语务必准确、清晰,不得随意涂改,错误之处纠正时需用横线居中划出,并签署修改者姓名缩写及修改时间。患者姓名拼音缩写四格必须填满,两字姓名填写两字拼音前两个字母,三字姓名填写三字首字母及第三字第二字母,四字姓名填写每一个字的首字母。举例:张红 ZHHO 张红旗 ZHQI 欧阳校风 OYXF。所有选择项目的 □ 内用×标注。所有应填写数字的 □ 填写阿拉伯数字。缺省方框用 0 填写。例:20应在三格框中书写 0 2 0。 所有检验项目因故“未查或漏查”,请填写 ND,并注明原因;“不知道”则填入“UK”;“不能提供”或“不适用”则填入“NA”。 数据管理: 当所有病例报告表经双份输入并核对无误后,由数据管理员写出数据库检查报告,其内容包括研究完成情况(含脱落受试者清单)、入选/排除标准检查、完整性检查、逻辑一致性检查、离群数据检查、时间窗检查、合并用药检查、不良事件检查等。在审核会议上,由主要研究者、监查员、数据管理员和统计人员对受试者签署知情同意书、数据库检查报告中提出的问题做出决议,写出审核报告,数据库同时将被锁定。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data acquisition: According to the original observation records of the subjects, the investigators of the clinical research project application form of the Affiliated Hospital of Guangdong Medical University will record the data in a timely, complete, correct and clear manner. The questionnaire that has been reviewed and signed by the Ombudsman shall be sent to the Clinical Research Data Manager in a timely manner. The exchange of questions and answers between them shall be in the form of a questionnaire, which shall be kept for future reference. A Case Report Form (CRF) is used to record data from each subject during the course of the trial. Therefore, the CRF must be clear and complete and be filled out with a black signature pen. The data and terms must be accurate and clear, and shall not be altered at will, and the correction of errors shall be marked with a horizontal line in the center, and the initials of the person who modified the name and time of modification shall be signed. The four boxes of the patient's name must be filled in, the first two letters of the two-character name must be filled in, the three-character name must be filled in the first letter of the three-character name and the second letter of the third word, and the four-character name must be filled in the first letter of each word. Example: Zhang Hong ZHHO Zhang Hongqi ZHQI Ouyang School Spirit OYXF. All selected items are annotated with × within the □. All □ that should be filled in with numbers are filled in Arabic numerals. The default box is filled in with 0. For example, 20 should be written 0 2 0 in a three-box box. All inspection items are "not checked or omitted" for some reason, please fill in ND and indicate the reason; "I don't know" is "UK"; For "not available" or "not applicable", enter "NA". Data Management: When all the case report forms are entered in double copies and checked to be correct, the data manager will write a database check report, which includes the completion of the study (including the list of dropped subjects), the inclusion/exclusion criteria check, the completeness check, the logical consistency check, the outlier data check, the time window check, the concomitant medication check, the adverse event check, etc. At the review meeting, the principal investigator, monitor, data administrator and statistician will make a decision on the questions raised in the respondent's informed consent form and database inspection report, and write an audit report, and the database will be locked at the same time. |
