摘要

目的:升高的红细胞分布宽度(RDW)和降低的血细比值(HCT)水平与慢性阻塞性肺疾病(COPD)患者的不良预后相关,但其在急性加重期COPD(AECOPD)患者的重症监护室(ICU)中的意义尚不明确。与单一指标相比,RDW/HCT比值可能提供更全面的评估,潜在地提高预测准确性。此外,RDW/HCT比值在改进传统ICU评分系统中的作用尚未得到探索。

方法:通过ROC曲线分析确定最佳RDW/HCT比值截断点,将患者分为高比值组和低比值组。采用单变量和多变量Logistic回归分析、Kaplan-Meier生存曲线及倾向评分匹配(PSM)评估RDW/HCT比值与28天全因死亡率之间的关系。通过受试者工作特征曲线下面积(AUC)评估RDW/HCT比值相较于传统ICU评分系统的预测价值。此外,利用eICU数据库验证RDW/HCT比值与AECOPD患者死亡率之间关联的稳健性。

结果:共纳入624名患者,其中低RDW/HCT比值组361人,高比值组263人。PSM后获得145对基线特征平衡的匹配患者。多变量Logistic回归分析显示,与RDW/HCT比值<0.473的患者相比,RDW/HCT比值≥0.473的患者28天全因死亡率显著升高(p < 0.001)。将RDW/HCT比值与SOFA评分结合显著提高了诊断准确性(p=0.029)。

结论:RDW/HCT比值是ICU中AECOPD患者28天全因死亡率的独立预测因子。在系统性评估患者之前,它可用于初步评估疾病严重程度,显示出其在早期评估中的潜在价值。在综合评估中,将RDW/HCT比值与SOFA评分结合使用可进一步提高预测准确性。
