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:

数据采集和管理系统:测试完善中,后续更新; 1.病例报告表(eCRF) 本研究由课题所在项目组参与单位开发EDC系统供本课题专用。采用电子病例报告表(eCRF)采集数据。研究者使用EDC系统中研究者终端收集数据(如签署知情同意书、填写罗马IV诊断问卷、IBS-SSS量表、HAMD和HAMA量表评估、用药、不良事件记录),需要患者完成的量表由患者在患者终端完成(IBS-QOL、每周/月疗效评估)。 研究者对所有入组患者(包括入组、脱落、剔除病历)每次访视均应完整准确地书写病历,包括与研究相关的主要内容。本单位就诊病历和原始化验单一并保存在病历系统中,作为溯源资料。 2.研究人员培训和数据采集质量控制 所有合格的研究人员再研究启动前接受统一培训,以确保他们对研究方案、操作步骤、量表评估和CRF填写有一致的理解。 EDC系统设置了数据采集的完整性要求,确保数据采集完整性。对治疗药物剂量改变、治疗更改、已经发生的记录错误的改正或遗漏的补充记录,需要注明并确认。 本研究没有雇用专门的CRO和CRC,没有专门的数据和安全检察委员会。主要研究者将定期对各研究中心的数据质量和安全性进行抽查。 3.数据库的设计和管理 EDC系统为本课题专门使用设计。仅授权人员才可进入这一系统。除了系统内部监查员、PI和授权研究助理定期监查之外,还将采用程序编辑监查和人工审核程序,审核数据的完整性、逻辑性以及试验方案的遵循性。

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

Data acquisition and management system: testing and improvement, follow-up update; 1. Case Report Form (eCRF) In this study, one participating team of the program is in charge of special EDC system development for this project. Data are collected using electronic case report form (eCRF). Investigators use the authorized individual code to access the EDC system to collect data (such as obtaining informed consent, filling in the Rome IV diagnostic questionnaire, IBS-SSS scale, HAMD and HAMA assessment, medication, advised events), and the patients can access subjects’ terminal with authorized link to complete subject' report and evaluation (i.e. IBS-QOL, weekly/monthly efficacy assessment). The investigators also need complete medical record for each study visit, include the major contents of the study in the medical records. These medical records and study related examination reports are stored in the site medical recording system as traceability data. 2. Investigators training and quality control of data collection All qualified investigators received the uniform training prior to the initiation of the study to ensure that they have a consistent understanding of the study protocol, procedures, instruments evaluation, and case report form completion. EDC system sets up the integrity requirements of data collection to ensure the integrity of data acquisition. Additional records of therapeutic drug dose changes, treatment changes, corrections or omissions of recorded errors that have occurred should be noted and confirmed. No CRO or CRC was employed in this study, no data and safety monitoring committee. The PI of this study will regularly carry out data quality and safety sampling inspect for each site. 3. Database design EDC system is specially developed for this project. To access to the system is restricted to authorized personnel only. In addition to regular audits by internal system monitors, PI's, and authorized investigator assistants, procedural editing audits and manual audits will be used to review data integrity, logic, and adherence to study protocols.
