高龄住院患者肺部感染的危险因素分析

目的探讨高龄住院患者肺部感染的危险因素。方法随机选取228例80岁以上的高龄患者作为研究对象,收集患者临床资料,分析探讨高龄患者肺部感染的危险因素。结果肺部感染组血红蛋白、总蛋白、白蛋白均低于无肺部感染组,血糖高于无肺部感染组,差异有统计学意义(P<0.05),而两组尿素氮、肌酐差异无统计学意义(P>0.05)。与无肺部感染组相比,肺部感染组患者年龄更大,男性、合并贫血、合并慢性阻塞性肺疾病比例更高,不能自主进食、长期卧床、痴呆比例更高,差异均有统计学意义(P<0.05)。logistic回归分析提示年龄、合并慢性阻塞性肺疾病、不能自主进食、长期卧床是高龄患者肺部感染的独立危险因素,血清总蛋白、白蛋白是高龄患者肺部感染的保护因素。结论年龄、合并慢性阻塞性肺疾病、不能自主进食、长期卧床、低蛋白血症是高龄患者肺部感染的主要危险因素。

Risk factors of pulmonary infection in aged hospitalized patients

Objective To investigate the risk factors of pulmonary infection in aged hospitalized patients.Methods A total of 228 elderly patients aged over 80 were randomly included as research objects.The patients′clinical data were collected to evaluate the related factors of the pulmonary infection in elderly hospitalized patients.Results Compared with the non-pulmonary infection group,the hemoglobin,total protein and albumin were lower and blood sugar was higher in pulmonary infection group(P<0.05).While the differences of urea nitrogen and creatinine between the two groups were not significant(P>0.05).In the pulmonary infection group,the proportion of patients with older age,male,combined with anemia,chronic obstructive pulmonary disease(COPD)and lack of the ability to eat independently,long-term bedridden state and dementia were higher than that in non-pulmonary infection group(P<0.05).Logistic regression analysis showed that age,combined with COPD,lack of the ability to eat independently,long-term bedridden state were independent risk factors,and the serum total protein and albumin were protective factors of pulmonary infection in elderly patients.Conclusions Age,combined with COPD,lack of the ability to eat independently,long-term bedridden state and hypoproteinemia are risk factors of pulmonary infection in elderly hospitalized patients.
