死亡率和抗生素时间在深度学习衍生的生存败血症运动风险组:一个多中心研究
Research square
|April 16, 2025
概括
深度学习模型客观地分层了败血症患者. 低风险的患有可能发生败血症且不太可能发生休克的患者在服用抗生素1小时和3小时时隔后的死亡率相似.
科学领域:
- 关键护理医学 关键护理医学
- 传染性疾病 传染性疾病
- 医疗保健中的人工智能
背景情况:
- 目前的生存性败血症运动 (SSC) 准则建议根据败血症概率和休克存在的抗生素时间.
- 缺乏基于这些风险群体的客观患者分层和结果分析.
- 需要数据驱动的方法来完善败血症管理协议.
研究的目的:
- 使用深度学习 (DL) 模型客观地分层疑似败血症患者.
- 根据DL衍生的风险组和抗生素时间分析患者的结果,特别是短期死亡率.
- 为了评估抗生素给药时间对不同败血症风险层中的死亡率的影响.
主要方法:
- 观察性队列研究,利用来自两个卫生系统 (2016-2024) 的前性收集数据.
- 两种DL模型用于根据败血症概率和休克可能性将患者分为四个风险组.
- 主要结局:短期死亡率 (住院死亡率或过渡到临终关怀).
主要成果:
- 分析了34,163名可能患有败血症的成年患者.
- 风险组之间的死亡率有显著差异,高震荡可能性的群体的死亡率更高.
- 患有可能发生败血症且不太可能发生休克的患者,无论在1小时内还是3小时内服用抗生素,死亡率都相似.
结论:
- 使用DL模型的客观风险分层可以为败血症管理提供信息.
- 对于低风险患者 (不太可能发生休克),更温和的抗生素给药时间 (例如3小时) 可能不会增加死亡率.
- 研究结果表明,在某些败血症患者群体中,抗生素的使用可能更为明智,这需要进一步的前性验证.

Actuarial Approach
42
The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.
Consider the example of a high-risk surgical procedure with significant early-stage mortality. A two-year clinical study is conducted,...

Comparing the Survival Analysis of Two or More Groups
90
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...
