Eur Respir J:广谱抗生素使用与社区获得性肺炎患者不良结局的关系

2019-07-05 xing.T MedSci原创

由此可见,广谱抗生素似乎与社区获得性肺炎患者的死亡率增加和其他不良结局相关。

在调整混杂因素后,广谱抗生素的使用是否与社区获得肺炎的预后不良相关?

近日,呼吸疾病领域权威杂志Eur Respir J上发表了一篇研究文章,研究人员对美国四所医院急诊科收治的1995名肺炎患者进行了一项回顾性观察性队列研究。研究人员使用了多变量回归来评估广谱抗生素对30天死亡率、住院时间、费用和艰难梭菌感染(CDI)的影响。为了解决指征偏倚,研究人员使用多重(个体提供者)广义线性混合模型开发倾向评分,以执行治疗加权的逆概率(IPTW)来估计治疗中的平均治疗效果。研究人员还手动审查了抗生素相关不良事件的死亡病例样本。

39.7%的患者接受了广谱抗生素治疗,但耐药性病原体仅恢复了3%。广谱抗生素与未加权多变量模型(OR为3.8,95%CI为2.5-5.9; p<0.001)和IPTW分析(OR为4.6,95%CI为2.9-7.5; p<0.001)的死亡率增加相关。通过任一分析使用广谱抗生素也与更长的住院时间、更高的成本和更高的CDI相关。与广谱抗生素使用无关,医疗相关肺炎与死亡率无关。在人工审查中,研究人员确定了17.5%的死亡病例为抗生素相关事件。

由此可见,广谱抗生素似乎与社区获得性肺炎患者的死亡率增加和其他不良结局相关。
