The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

After the research report is published, we choose to upload the original data to Zenodo (https://zenodo.org/) so that researchers can access and replicate our results.

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) 设计阶段 严格制定研究方案,并按照研究方案执行。在大量查阅相关文献及专家小组讨论后设计新生儿血管通路相关性血栓风险评估内容,在咨询相关专家后,进一步对其进行修改和完善,以确保评估内容的针对性和全面性。 建立协调中心,对每个中心的人员进行培训,监督数据的管理、分析和发表,协调操作手册、表格及标准化质量控制程序。 (2)实施阶段 病例的筛查和核实由研究者及经过培训的课题组各个中心成员共同完成,根据GCP规范以确保病例资料的收集按照统一的标准实行。研究实施阶段过程中课题组另一名成员每日进行核查,检查资料的完整性和真实性,发现遗漏和错误后再次进入病例系统进行核对,以保证资料的准确性和完整性。 (3)数据录入及管理阶段 资料的整理、审核阶段,对每份调查数据进行认真审核复查,应用Epidata3.0软件进行数据录入。录入时关注资料的完整性和准确性,及时反馈,发现缺项、漏项、错误、重复内容时及时登录电子病历系统查询,以保证数据的完整性和可靠性。

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

(1) Design phase Formulate the research plan strictly and implement it according to the research plan. The content of risk assessment for thrombosis associated with neonatal vascular access was designed after extensive review of relevant literature and expert panel discussion, and further modified and improved after consulting relevant experts to ensure pertinency and comprehensiveness of the assessment content. Establish coordination centers, train personnel in each center, supervise the management, analysis and publication of data, coordinate operation manuals, forms and standardized quality control procedures. (2) Implementation phase The screening and verification of cases was carried out jointly by the investigators and trained members of each center of the research group, in accordance with the GCP specification to ensure that the collection of case data was carried out in accordance with uniform standards. During the research implementation stage, another member of the research team checked the completeness and authenticity of the data every day, and entered the case system again for verification after discovering omissions and errors to ensure the accuracy and integrity of the data. (3) Data entry and management stage At the stage of data sorting and review, each survey data was carefully reviewed and reviewed, and Epidata3.0 software was used for data entry. Pay attention to the integrity and accuracy of the data when entering, give feedback in time, and log in to the electronic medical record system in time when missing items, missing items, errors, and repeated contents are found to ensure the integrity and reliability of the data.
