机器学习模型可以预测机械通风患者的生存率,超过SOFA得分. 这有助于在重症监护病房 (ICU) 的早期分拣和临床判断.
科学领域:
- 密集护理医学 密集护理医学
- 医疗保健中的机器学习
- 临床预后 临床预后
背景情况:
- 由于医生与患者的比例较低,重症监护室 (ICU) 在为机械通风患者提供一致的护理方面面临着挑战.
- 准确的预后评估和资源分配对于改善患者的治疗结果至关重要.
研究的目的:
- 开发和评估一种机器学习 (ML) 模型,用于预测机械通风ICU患者的存活率.
- 为了将ML模型的性能与顺序器官衰竭评估 (SOFA) 评分进行比较.
主要方法:
- 从三个重症监护室的660名机械呼吸患者的回顾性分析.
- 使用十倍交叉验证开发二进制分类ML模型.
- 使用Shapley添加式解释 (SHAP) 和随机森林进行特征选择.
主要成果:
- 使用SHAP选择的特征的K-近邻 (KNN) 模型实现了0.84的AUROC和0.80的准确性.
- 最重要的预测特征包括SOFA分数,国际规范化比率 (INR) 和呼吸率.
- 与单独的SOFA得分相比,ML模型显示出更高的性能 (AUROC 0.73,准确率为 0.73).
结论:
- 机器学习模型可以帮助临床医生在早期的患者分拣和知情决策.
- 这些模型提供了对传统评估工具的补充支持,例如高风险ICU设置中的SOFA评分.
- 自动预测预后可以提高临床判断力,并为ICU医生及时发出警报.
