研究目的:

急诊胃肠道出血属于典型的时间敏感型疾病,其救治效果在很大程度上取决于紧急胃肠镜检查的启动与完成时间。尽管现有指南建议尽早实施内镜,但在实际临床环境中,流程延迟的具体环节、延迟程度及其对患者临床结局的影响尚缺乏系统量化。本研究旨在基于我院急诊抢救室真实数据,全面评估急诊胃肠镜流程及时性与临床结局之间的关系。 本研究拟实现以下具体目标: 1. 描述急诊胃肠道出血患者内镜流程的现状与时间分布,包括收入抢救室、内镜启动、内镜完成等关键时间节点,并识别潜在的流程延迟环节; 2. 评估急诊胃肠镜流程及时性与主要临床结局之间的关联,包括再出血率、转入ICU的比例、住院时间及院内死亡等结局指标; 3. 探索不同时间窗完成内镜检查的临床效益差异,明确早期内镜(<=6h、6–12h、12–24h、>24h)是否与更好的临床结局相关; 4. 识别急诊胃肠镜流程中的关键时间阈值,如超过某一时间点是否显著增加不良结局风险,为临床决策提供量化依据; 5. 为医院急诊流程管理与质量改进提供可操作的建议,包括优化急诊-内镜科协作机制、完善绿色通道、调整资源配置及提高流程效率的方向。 本研究的最终目标是通过定量化分析时间节点对结局的影响,构建“流程及时性—诊疗效率—临床结局”的证据链条,从而推动急诊内镜流程的标准化与优化,提高急诊胃肠道出血患者的整体救治质量与预后水平。  

Objectives of Study:

The overarching goal of this study is to construct an evidence-based framework linking workflow timeliness, diagnostic and therapeutic efficiency, and clinical outcomes through quantitative analysis of key temporal metrics, thereby facilitating the standardization and optimization of emergency endoscopy pathways and ultimately improving the quality of care and prognosis for patients with acute gastrointestinal bleeding.
