背景情况:
- 冠状动脉绕道移植 (CABG) 是一项复杂的手术程序,存在重大风险.
- 伴随性疾病在接受CABG的患者中很普遍,并且与不良心血管结果有关.
- 预测住院死亡率对于CABG手术中的风险分层和患者管理至关重要.
研究的目的:
- 评估使用埃利克沙瑟并发症指数 (ECI) 对接受CABG患者住院死亡率的并发症的预测能力.
- 评估年龄调整对医院住院死亡率ECI预测准确性的影响.
- 为了比较ECI在不同数量的CABG程序 (1,2,3和4+) 中的预测性表现.
主要方法:
- 利用国家住院样本数据库来识别2015年第四季度至2020年期间接受CABG的患者.
- 采用后勤回归模型来确定基于ECI的医院死亡率预测最适合的模型.
- 根据年龄调整了ECI以评估其增强的预测能力.
主要成果:
- 在所有CABG组中,ECI显示了对住院死亡率的适度预测能力 (c-统计值0.6-0.7).

Kaplan-Meier Approach
83
The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...

Comparing the Survival Analysis of Two or More Groups

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...
