研究目的:

基于多中心前瞻性数据,运用单中心数据开发构建并再进行多中心验证的一个多变量临床预测模型,用于评估≥65岁老年患者在镇静/麻醉下胃镜检查和(或)治疗过程中发生术中低血压的风险,以支持术前风险分层并为围检查期风险识别提供量化参考。并将预测模型转化为可视化、便捷的临床辅助工具(如列线图、在线风险计算器或简易评分量表),为不同层级麻醉医生的术前评估与风险沟通提供参考,促进模型在门诊镇静麻醉场景中的可用性与可推广性。  

Objectives of Study:

Based on multicenter prospective data, a multivariable clinical prediction model was developed using single-center data and subsequently validated in multiple centers to assess the risk of intraoperative hypotension during gastrointestinal endoscopy and/or treatment in elderly patients aged ≥65 years under sedation/anesthesia. This model aims to support preoperative risk stratification and provide a quantitative reference for identifying perioperative risks. The prediction model will be transformed into a visual and user-friendly clinical decision support tool (such as a nomogram, online risk calculator, or simple scoring scale), serving as a reference for preoperative assessment and risk communication among anesthesiologists at different levels, thereby enhancing the model's usability and applicability in outpatient sedation anesthesia settings.

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:

本研究采用标准化纸质版病例报告表(Case Report Form, CRF)进行数据采集。所有数据由研究人员在数据收集后统一录入至Excel电子表格中,数据录入由两名研究人员分别进行双人核对,确保录入准确性。数据文件保存在设密码的计算机中,由项目负责人专人管理,未经授权不得访问。目前未采用专门的EDC系统,但数据将按研究计划和伦理审批要求定期备份、保密管理。

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

A standardized paper-based Case Report Form (CRF) will be used for data collection. All data will be uniformly entered into Excel spreadsheets by trained researchers. Double data entry and verification will be performed by two independent staff members to ensure accuracy. Data files will be stored on a password-protected computer and managed exclusively by the principal investigator. No EDC system is currently used. Data will be regularly backed up and managed confidentially in accordance with the study protocol and ethical requirements.
