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:
|
一、数据采集
数据采集实行双人双次录入,分别由数据录入员和研究者完成一、二次录入,保证研究数据的录入客观、准确。
二、数据管理
1 定义原始数据
(1)受试者的医疗文件,包括门诊病历、住院病历、理化检查报告等。
(2)临床研究过程文件,包括知情同意书、筛选表、入选表、用药记录、实验室记录、科研病例、病例报告表等。
2 数据记录与保存的规定
(1)数据录入采用二次录入方法,由不同录入人员分别重复录入同一份病例报告表格,以两次或两人的输入值相互核对,两者一致的存入数据库。
(2)研究者应当保证临床研究的病例报告表(CRF)和所需报告中的数据的准确性、完整性、易辨性、及时性以及可溯源性。遵守源文件保存和查阅规定。数据收集要求及时、完整、准确。①及时:数据应在8小时内完成原始记录,24小时内完成病例观察表的记录;②完整:收集研究数据,就是要求收集所有研究对象的全部数据;③准确:研究者在收集资料或填写观察表格时需经过一定的培训,或者至少需要在填写前熟悉填写要求和注意事项,并通过检查来确认所有的资料收集者都能较为一致地掌握资料的收集方法。
(2)为保证国家中医药管理局和研究单位的评价与监督,研究者应保存所有研究资料,包括对所有参加受试者的确认(能有效地核对不同的记录资料,如CRF表和医院原始记录)、所有原始的有签名的患者知情同意书、所有CRF表、药品发放的详细记录等。当课题通过鉴定验收后,将所有研究资料转交课题负责单位科研管理处,并保存至研究结束后5年。
3 数据报告的方式
每个临床试验中心应在完成至少5份CRF后,通过临床监查员及时送交数据管理员,以便建立相应的数据库,所有数据将采用计算机软件编制数据录入程序进行双份录入。数据管理员保证将CFR表数据完整真实的录入计算机。
4 数据核查的规定
对数据进行盲态审核,并认为所建立的数据库正确后,将由主要研究者、统计分析人员对数据进行锁定。锁定后的数据文件不允许再作变动。数据库将交统计分析人员按统计计划书要求进行统计分析。
5 数据疑问与答疑的规定
有疑问的数据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。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:
|
Data collection
Data acquisition is performed by double entry, which is completed by data entry personnel and researchers respectively, so as to ensure the objectivity and accuracy of research data entry.
Data management
define the raw data
(1) medical documents of subjects, including outpatient medical records, inpatient medical records, physical and chemical examination reports, etc.
(2) clinical research process documents, including informed consent form, screening form, inclusion form, medication record, laboratory record, scientific research case, case report form, etc.
2. Provisions for data recording and preservation
(1) data entry adopts the method of secondary entry, in which the same case report form is repeatedly entered by different input personnel, and the input values of two or more people are checked with each other, and the two are stored in the database in accordance with each other.
(2) researchers should ensure the accuracy, integrity, legibility, timeliness and traceability of the case report form (CRF) and the data in the required reports. Comply with source document storage and access regulations. Data collection should be timely, complete and accurate. (1) timely: the original records of data should be completed within 8 hours, and the records of case observation table should be completed within 24 hours; (2) complete: collect research data, is required to collect all the research objects of all the data; (3) accuracy: researchers need to go through certain training when collecting data or filling in observation forms, or at least be familiar with filling in requirements and precautions before filling in, and check to ensure that all data collectors can relatively uniformly grasp the data collection methods.
(2) to ensure that the state administration of traditional Chinese medicine and the research units of evaluation and supervision, researchers should keep all information, including confirmation of all the participants in subjects (can effectively check records of different materials, such as tables and CRF hospital records), all the original signature of patients' informed consent, all CRF table, the release of detailed records, etc. After the project passes the appraisal and acceptance, all research data will be transferred to the scientific research management office of the project responsible institution, and kept for 5 years after the end of the research.
3. Way of data reporting
Each clinical trial center shall, upon completion of at least 5 copies of the CRF, promptly send it to the data manager through the clinical inspector for the purpose of establishing the appropriate database. All data will be double-entered using computer software to prepare the data entry program. The data administrator ensures that the CFR table data is completely and truly entered into the computer.
4. Provisions for data verification
After blind review of the data and the conclusion that the established database is correct, the data will be locked by the main researchers and statistical analysts. Locked data files are not allowed to change. The database will be handed over to the statistical analyst for statistical analysis according to the requirements of the statistical plan.
Data question and answer the regulation
The data sheets in question are forwarded to the investigator by the clinical inspector for data review, and the investigator should reply and return as soon as possible.
