研究目的:

比较已有≥1个周期IVF/ICSI周期, 前个周期D3未获可利用胚胎(6细胞及以上,碎片率小于25%,卵裂球无明显大小不均及其他异常),本周期 D2 与 D3 胚胎移植对至少1个胚胎的体外受精 / 卵胞浆内单精子注射(IVF/ICSI)患者首个移植周期活产率的差异。  

Objectives of Study:

Compare patients who have had >=1 previous IVF/ICSI cycles where no usable embryos were obtained on day 3 (6 cells or more, fragmentation rate less than 25%, blastomeres with no obvious size inequality or other abnormalities), in terms of the difference in live birth rates in the first transfer cycle for patients undergoing IVF/ICSI with at least one embryo transferred on day 2 versus day 3 in the current cycle.

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:

负责临床试验数据管理的人员均经过GCP、相关法律法规、相关SOP,以及数据管理的专业培训。申办者是保证临床数据质量的最终责任人。由申办者制定质量管理评价程序、质量管理计划与操作指南,并且设立稽查部门。由不直接涉及试验的人员定期对质量体系的依从性进行系统性检查。此外,申办者保证数据的完整性,监督数据管理过程的合规性。研究者应确保以CRF或其他形式报告给申办者的数据准确、完整与及时,而且应保证CRF上的数据来自于受试者病历上的源数据,并必须对其中的任何不同给出解释。监查员应根据源文档核查CRF上的数据,一旦发现其中有错误或差异,应通知研究者,并根据所发现的错误或差异,记录相应的质疑,以确保所有数据的记录和报告正确和完整。数据管理员应按照研究方案的要求,参与设计CRF、建立数据库、对数据标准进行管理、并建立和测试逻辑检验程序。在CRF接收后,录入人员要对CRF作录入前的检查;在CRF数据被录入数据库后,利用逻辑检验程序检查数据的有效性、一致性、缺失和正常值范围等。数据管理员对发现的问题应及时清理,可通过向研究者发放数据质疑而得到解决。所有数据将加密保存,密码仅提供给研究人员。临床试验数据管理系统必须具备可以为临床试验数据提供可溯源性的性能。CRF中数据应当与源文件一致,如有不一致应作出解释。对CRF中数据进行的任何更改或更正都应该注明日期、签署姓名并解释原因(如需要),并应使原来的记录依然可见。临床试验数据的稽查轨迹,从第一次的数据录入以及每一次的更改、删除或增加,都必须保留在临床试验数据库系统中。稽查轨迹应包括更改的日期、时间、更改人、更改原因、更改前数据值、更改后数据值。此稽查轨迹为系统保护,不允许任何人为的修改和编辑。稽查轨迹记录应存档并可查询。

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

The personnel responsible for clinical trial data management have received professional training in GCP, relevant laws and regulations, relevant SOPs, and data management. The applicant is the ultimate responsible person for ensuring the quality of clinical data. The applicant shall develop quality management evaluation procedures, quality management plans, and operational guidelines, and establish an inspection department. Regular and systematic inspections of the compliance of the quality system are conducted by personnel who are not directly involved in the experiment. In addition, the applicant ensures the integrity of the data and supervises the compliance of the data management process. Researchers should ensure that the data reported to sponsors in CRF or other forms is accurate, complete, and timely, and that the data on CRF comes from the source data on the subject's medical records, and any differences must be explained. The inspector should verify the data on the CRF based on the source document. Once errors or differences are found, the researcher should be notified, and corresponding doubts should be recorded based on the errors or differences found to ensure that all data is recorded and reported correctly and completely. The data administrator should participate in the design of CRF, establishment of database, management of data standards, and establishment and testing of logic verification procedures in accordance with the requirements of the research plan. After receiving the CRF, the entry personnel should conduct a pre entry inspection of the CRF; After CRF data is entered into the database, a logic verification program is used to check the validity, consistency, missing values, and normal range of the data. The data administrator should promptly clean up any issues discovered, which can be resolved by issuing data queries to researchers. All data will be encrypted and stored, and passwords will only be provided to researchers. The clinical trial data management system must have the capability to provide traceability for clinical trial data. The data in CRF should be consistent with the source file, and any inconsistencies should be explained. Any changes or corrections made to the data in the CRF should be dated, signed, and explained (if necessary), and the original records should still be visible. The audit trajectory of clinical trial data, from the first data entry and every change, deletion or addition, must be retained in the clinical trial database system. The inspection trajectory should include the date, time, person who made the change, reason for the change, pre change data values, and post change data values. This inspection trajectory is protected by the system and cannot be modified or edited by anyone. The audit trajectory records should be archived and searchable.
