CT影像评分对社区获得性肺炎预后的评估价值分析

Value of CT Score in Evaluating the Prognosis of Community Acquired Pneumonia

目的分析CT影像评分对社区获得性肺炎预后的评估价值。方法本文所选80例重症社区获得性肺炎患者均为我院2015年3月—2018年5月所收治,对其胸部CT影像进行回顾性分析,按照胸部CT对急性加重特发性肺纤维化CT评分(AE-IPF)进行计算,并探讨AE-IPF评分与疾病预后的相关性。结果在AE-IPF评分方面,院内存活患者与院内死亡患者比较差异无统计学意义(P>0.05);与28 d存活患者相比,28 d死亡患者的AE-IPF评分显著增加(P<0.05)。与院内存活患者相比,院内死亡患者的APACHEⅡ评分显著降低(P<0.05);与28 d存活患者相比,28 d死亡患者的APACHEⅡ评分显著降低(P<0.05)。Person相关分析发现,患者的AE-IPF评分和APACHEⅡ评分存在线性相关,表现为正态分布。结论单一的影像学特征并不能对社区获得性肺炎患者的预后进行判断,而采用CT影像评分能对社区获得性肺炎患者的28 d预后进行准确判断。

Objective To analyze the value of CT image score in prognosis of community acquired pneumonia.Methods 80 patients with severe community acquired pneumonia were treated in our hospital from March 2015 to May 2018.Their chest CT images were retrospectively analyzed.The CT score of acute exacerbated idiopathic pulmonary fibrosis(AE-IPF)was calculated according to chest CT.The relationship between AE-IPF score and prognosis of the disease was discussed.Result There was no significant difference in AE-IPF score between living patients and dead patients in hospital(P>0.05):compared with 28-day survivors,the AE-IPF score of 28-day survivors increased significantly(P<0.05).Compared with living patients in hospital,APACHEII score of dead patients in hospital was significantly lower(P<0.05),and APACHEII score of dead patients in 28 days was significantly lower(P<0.05)than that of survived patients in 28 days.Person correlation analysis showed that there was a linear correlation between AE-IPF score and APACHEEII score,which showed a normal distribution.Conclusion Single imaging features can not judge the prognosis of patients with community acquired pneumonia,but CT image score can accurately judge the prognosis of 28 days of patients with community acquired pneumonia.
