我国社区获得性肺炎病情评估标准与PSI标准的比较研究

摘要

Objective To compare China' s community-acquired pneumonia disease assessment standard with PSI standard in assessing the condition of the patients with the community-acquired pneumonia ( CAP). Methods Selected 120 patients as the subject of study. All patients were divided into low, medium and high risk group according to Chinese and PSI score standards. Compared the assessment system in predicting hospital death, ICU sensitivity, specificity, positive predictive value, and negative predictive value in each group. Results The Chinese standard brought out the high sensibility in predicted death and ICU stay,while the specificity is lower,compared to low sensitivity of PSI standard, and high specificity. Conclusion Our standards are different from PSI score in selecting patients with low risk and in predicting death and ICU stay.%目的 比较我国社区获得性肺炎(CAP)病情评估标准与PSI标准的差异.方法 120例CAP患者作为研究对象,分别按PSI评分与我国标准分为低、中、高危组.比较两种方法系统预测死亡和ICU住院的敏感度、特异度、阳性预测值、阴性预测值.结果 我国标准预测死亡及入住ICU的敏感度高,而特异度较低,相反PSI标准敏感度低,而特异度高.结论 在筛选低风险患者、预测死亡和入住ICU方面,PSI评分标准和我国标准各有差异.
