PSI评分在重症肺炎患者预后判断中的应用价值

The application value of prognosis about PSI in severe pneumonia cases

目的探讨重症肺炎患者预后与肺炎严重程度(pneumonia severity index,PSI)评分的关系。方法收集本院32例重症肺炎患者的临床资料,计算PSI分值,观察不同PSI分值患者病死率。结果 PSI≤50分组病死率为0,51～70分组病死率为12.50%,71～90分组病死率为30.00%,91～130分组病死率为50.00%,>130分组病死率为71.43%,5组病死率差异有统计学意义,P<0.01。结论 PSI评分可以用来预测重症肺炎患者的预后。

Objective To investigate the relationship between PSI and the prognosis of severe pneumonia cases.Methods The clinical data of 32 severe pneumonia cases in the respiratory department of our hospital were collected.Computed the score of PSI,the motalities in different PSI scores were compared.Results The motality in PSI score≤50 group was 0.The motality in PSI score 51-70 group was 12.50%.The motality in PSI score 71-90 group was 30.00%.The motality in PSI score 91-130 group was 50.00%.The motality in PSI score 130 group was 71.43%.There were significant differences a mong five groups,P 〈0.01.Conclusion The study shows that PSI is applicable to estimate the prognosis of severe pneu monia cases.
