老年人社区获得性肺炎的预后风险分析

目的探索影响老年人社区获得性肺炎(CAP)预后的危险因素。方法使用Logistic回归模型分析98例CAP患者,男69例,女29例,(75.1±6.7)(65~91)岁预后的危险因素。结果病死率为12.2%,单因素分析发现卧床、合并基础疾病的数量、合并神经系统及呼吸系统疾病、是否发生意识障碍、血白蛋白<30 g/L、尿素氮>10.35 mmol/L,PSI和CURB-65评分系统较高均为影响病死率的危险因素。结论 PSI和CURB-65评分系统可以评估CAP预后;而意识障碍及尿素氮>10.35mmol/L为其预后差的独立危险因素。

Elderly community-acquired pneumonia with prognostic factor analysis

Objective To explore the risk factors of morality of community-acquired pneumonia（CAP）in the elderly.Methods Logistic regression model was used to analyze the risk factors of mortality of 98 CAP cases,69 males and 29 females,aged（75.1±6.7）（65-91）.Results The mortality of these patients was 12.2%.Univariate analysis showed that bed confinement,number of underlying diseases,existence of complicated neurological and respiratory disease,conscious disturbance,albumin value 30g/L,urea nitrogen10.35mmol/L,high scores in PSI（Pneumonia Severity Index）and CURB-65（Confusion,Uremia,Respiratory rate,Low blood pressure,Age 65 years or greater）were the risk factors of the mortality of CAP in the elderly.Conclusions PSI and CURB-65 scoring system is able to assess the prognosis of CAP;There were two independent risk factors：conscious disturbance and urea nitrogen10.35mmol/L.
