研究目的: |
(1)科学目标: 明确计划性时间窗择期剖宫产与常规时间剖宫产对母婴结局的影响差异,揭示非医学因素(如患者偏好时间)对围术期风险的作用机制,为优化剖宫产时间管理提供循证依据。 (2)临床目标: 建立基于循证医学的《择期剖宫产时间选择临床路径》,规范手术时间安排标准,降低因非必要时间调整导致的母婴并发症(如产后出血、新生儿低血糖等),提升围产期医疗质量。 (3)管理目标: 优化手术室资源配置策略,平衡患者需求与医疗安全,减少因时间冲突导致的资源浪费,提升患者满意度。 |

|
Objectives of Study: |
(1) Scientific Objectives: To determine the impact differences on maternal and neonatal outcomes between scheduled time-window elective cesarean delivery and conventionally timed cesarean delivery, elucidate the mechanisms of action of non-medical factors (such as patient time preference) on perioperative risks, and provide an evidence-based foundation for optimizing the timing management of cesarean delivery. (2) Clinical Objectives: To establish an evidence-based "Clinical Pathway for Timing Selection in Elective Cesarean Delivery," standardize the criteria for scheduling cesarean deliveries, reduce maternal and neonatal complications (such as postpartum hemorrhage and neonatal hypoglycemia) caused by unnecessary timing adjustments, and enhance the quality of perinatal healthcare. (3) Management Objectives: To optimize operating room resource allocation strategies, balance patient needs with medical safety, reduce resource wastage due to scheduling conflicts, and improve patient satisfaction. |

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: |
病例记录表(CRF):本研究设计有标准化的纸质病例报告表。CRF表包含了研究方案中定义的所有变量。研究人员在患者入院至出院期间,根据医疗文书实时填写CRF。 电子采集和管理系统(EDC):研究数据从纸质CRF转录至专为本研究创建的、经过密码保护的标准化电子数据库(使用Microsoft Excel软件)。数据录入过程采用“双人独立录入”的方式进行核对,以确保数据的准确性。电子文件存储于医院受控管理的安全服务器上,仅授权的研究团队成员可以访问。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Case Report Form (CRF): This study utilized standardized paper Case Report Forms. The CRFs encompassed all variables defined in the study protocol. Research staff prospectively completed the CRFs based on medical records during the period from patient admission to discharge. Electronic Data Capture (EDC) System: Data from the paper CRFs were transcribed into a standardized, password-protected electronic database created specifically for this study using Microsoft Excel. The data entry process employed a dual independent entry method for verification to ensure data accuracy. The electronic files are stored on a secure server under the hospital's controlled management, with access restricted to authorized research team members only. |
