概括
一种新的肝硬化风险工具用于分层化急诊室后死亡率 (CRISPE) 工具在预测急诊室肝硬化患者的短期死亡率方面表现强. 这种新的工具在风险分层方面优于现有的末期肝病模型 (MELD) 评分.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 紧急医疗 紧急医疗
- 临床决策 临床决策
背景情况:
- 临床决策工具 (CDI) 可以帮助风险分层和急诊室 (ED) 肝硬化患者的处置.
- 准确预测短期死亡率对于管理这些高风险患者至关重要.
研究的目的:
- 导出并内部验证一种新的CDI,即Cirrhosis Risk Instrument for Stratifying Post-Emergency Department Mortality (CRISPE) 对于14日和30日后ED死亡率,用于分层对待肝硬化风险工具.
- 为外部验证末期肝病模型 (MELD) 的得分,以预测ED肝硬化患者的相同结果.
主要方法:
- 一组2093名患有肝硬化的成年人被分析,使用了ED处置中可用的119个候选变量.
- 用10倍交叉验证的LASSO回归用于选择变量,以开发CRISPE-14和CRISPE-30模型.
- 使用接收器运行特征曲线 (AUROC) 下的面积和重新分类统计数据来比较CRISPE和MELD分数.
主要成果:
- CRISPE-14和CRISPE-30在MELD变种中表现出优越的性能,AUROC分别为0.824和0.829,而MELD 3.0的0.724和0.715.
- 与单独处理ED相比,CRISPE变体和MELD 3.0都显著改善了预测值和净重新分类.
- 与MELD 3.0.0相比,CRISPE-30实现了对患者死亡风险倾向的更有利的重新分类.
结论:
- 像CRISPE这样的临床决策工具可以有效地帮助对患有肝硬化的ED患者进行风险分层,并指导处置决策.
- 新的CRISPE CDI在预测短期死亡率方面显示出有希望的表现,并需要外部验证.
- 虽然MELD 3.0得分具有中等的性能,但现在已经得到了外部验证,用于预测ED肝硬化患者的短期死亡率.

Esophageal Varices-II: Clinical Features and Management
46
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
