老年患者医院获得性肺炎死亡危险因素分析

The risk factors resulting in death of senile patients from hospital-acquired pneumonia

目的了解老年患者医院获得性肺炎(hospital-acquired pneumonia,HAP)的死亡危险因素。方法回顾性分析2008年1月至2011年12月在我院老年科、康复科住院期间发生的HAP患者100例,其中死亡23例,存活77例,将存活患者与死亡患者分为两组。采用单因素分析老年患者HAP死亡的危险因素。结果死亡组和存活组在性别、留置胃管、伴随糖尿病等方面无统计学差异(P>0.05),而在年龄、卧床、白蛋白水平、血红蛋白水平、C-反应蛋白水平等方面均具有明显的统计学差异(P<0.05)。结论老年患者HAP的死亡率与高年龄、长期卧床、低白蛋白血症、贫血以及高C-反应蛋白水平相关。

Objective To analyze the possible risk factors that cause death in senile patients from hospital-acquired pneumonia （HAP）. Method 100 patients with HAP in the department of geriatrics and the department of rehabilitation from January, 2008 to December, 2011 were retrospectively analyzed. These patients consisted of 84 males （84%） and 16 females （16%） , and the age of patients ranged from 63 to 93 years（ mean age ＋ SD,77.56 ＋ 6.51 years）. Of all 100 patients, 23 patients died and 77 survived. The univariate analysis was used to evaluate the risk factors of death in senile patients with HAP. Findings There were not significant difference statistically in gender, indwelling gastric tube and diabetes between the patients who died and those who survived （ P 〉 0.05）. However, age, bed res, serum albumin level, hemoglobin level, C-reactive protein level were significantly different between both groups （ P 〈 0.05 ）. Conclusion The mortality rate of senile patient with HAP correlate to old age, long-term bed rest, hypoalbuminemia, anemia and high C-reactive protein level.
