目的研究老年医院获得性肺炎(HAP)预后的危险因素。方法收集患者信息,包括年龄、感染时间、是否存在基础性疾病、院内接触环境、患者日常生活环境和习惯、抗生素使用情况等可能影响HAP预后情况的危险因素,行统计学分析。结果年龄、发病时间早晚、是否联合使用抗生素对HAP预后影响不明显;是否存在基础疾病、院内接触环境与日常生活状况对HAP预后有显著影响(P<0.05);其中是否存在基础疾病与HAP预后成正相关关系(B>0,Exp(B)>1);院内接触环境与日常生活状况与HAP预后成负相关关系(B<0,Exp(B)<1)。结论存在心脑肺基础疾病、住院接触环境差与日常生活环境及习惯差三项是老年HAP的危险因素,适当控制可以改善其预后。
Objective To study the risk factors for the prognosis of elderly hospital acquired pneumonia (HAP). Methods The patients’ information including age, infection time, the existence of basic diseases, contact environment in hospital, daily living environment and habits of patients, antibiotic usage and other risk factors that could affect the prognosis of HAP were analyzed statistically. Results The age, the onset time, the combination of antibiotics had no obvious effect on the prognosis of HAP. The existence of underlying diseases, in-hospital exposure and daily living conditions had significant effects on the prognosis of HAP (P <0.05), and whether there was underlying disease or HAP prognosis (B> 0, Exp (B)> 1). There was a negative correlation between in-hospital contact environment and daily living status and HAP prognosis (B <0, Exp (B) <1). Conclusions There are three risk factors of heart and brain-lung diseases, poor contact environment in hospital, poor daily living environment and habits, which are the risk factors for elderly HAP. Appropriate control can improve their prognosis.
