老年营养风险指数 (GNRI) 与老年败血症患者的28天死亡率有关. 较低的GNRI得分与较高的死亡率相关,但这种关联在98.1.1的GNRI中停滞不前.
科学领域:
- 老年医学 老年医学
- 关键护理医学 关键护理医学
- 营养科学 营养科学
背景情况:
- 败血症在老年患者中具有显著的死亡风险.
- 老年营养风险指数 (GNRI) 是评估老年人营养状况的工具.
- 关于GNRI对老年败血症患者死亡率的影响存在争议.
研究的目的:
- 调查老年败血病患者入院时GNRI和28天死亡率之间的关联.
- 为了确定GNRI与死亡率之间是否存在非线性关系或值效应.
- 为了确定对GNRI水平有差异反应的子组.
主要方法:
- 使用MIMIC IV数据库 (2009-2019) 进行的回顾性队列研究.
- 包括2834名65岁及以上的败血病患者.
- 使用多变量考克斯回归,卡普兰-梅尔曲线和受限立方线的分析.
主要成果:
- GNRI与28天死亡率有显著的相关性 (HR=0.97,p<0.001).
- 限制性立方线分析揭示了一个L形的关联与一个转折点在GNRI 98.1.1.
- 在拐点以下,较低的GNRI与较高的死亡率有关;在它以上,这种关联减少了.
结论:
- 入院时的GNRI是预测老年败血症患者28天死亡率的有价值指标.
- GNRI与死亡率之间的关联是非线性的,在98.1.1的GNRI以上观察到的和效应.
- 在ICU中,GNRI可以帮助老年败血症患者的风险分层.
