队列研究 

Study design:

Cohort study 

研究目的:

根据复发性流产患者的全面病因筛查结果,包括基本特征、凝血功能指标、自身免疫指标、内分泌指标和妇科超声检查结果,及病人就诊后再次妊娠的结局,分析影响复发性流产的独立危险因素,构建并验证流产风险预测模型,用于预测复发性流产患者后续妊娠丢失的风险,对患者进行风险分级,筛出高危人群,指导临床进行早期干预和积极治疗,以提高妊娠成功率。  

Objectives of Study:

Based on the comprehensive etiological screening results of patients with recurrent pregnancy loss, including basic characteristics, coagulation function indicators, autoimmune indicators, endocrine indicators, and gynecological ultrasound examination results, as well as the outcome of subsequent pregnancy after the patient's visit, analyze the independent risk factors affecting recurrent pregnancy loss, construct and validate an abortion risk prediction model to predict the risk of subsequent pregnancy loss in patients with recurrent pregnancy loss, and classify the patient's risk, Screening high-risk populations and guiding clinical early intervention and active treatment to improve pregnancy success rates.

本研究部分数据通过初诊调查问卷在病人首次门诊就诊时对患者基本信息进行收集,部分数据通过上海交通大学医学院附属仁济医院门诊病历系统获得并填写病理报告表(CRF),之后通过EpiData软件进行数据录入。在数据录入过程中采用双人录入校对的方法,保证数据录入的完整性和准确性;数据的修改将由项目负责人审批核准;项目电子数据将严格保密,数据隐去受试者个人信息。病例报告表在完成录入后根据编号顺序归档由仁济医院东院妇产科专人保存在仁济医院东院妇产科。电子数据文件多备份保存,以防丢失损坏。所有原始档案按相应规定内的期限保存。

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

In this study, part of the data were collected through the initial questionnaire on the basic information of patients during their first outpatient visit, and part of the data were obtained through the outpatient medical record system of Renji Hospital affiliated with Shanghai Jiaotong University School of Medicine and filled in the pathology report form (CRF), after which the data were entered through EpiData software. A two-person entry proofreading method is used in the data entry process to ensure the completeness and accuracy of data entry; modifications to the data will be approved and ratified by the project leader; and the project's electronic data will be kept strictly confidential, with the data omitting the subject's personal information. The case report form will be filed according to the numbering sequence after the completion of the entry and will be stored in the Department of Obstetrics and Gynaecology of Yanji Hospital East Hospital by the specialists of the Department of Obstetrics and Gynaecology of Yanji Hospital East Hospital. Electronic data files were kept in multiple backups to prevent loss and damage. All original files are kept for the period of time specified in the respective regulations.
