摘要
目的探讨呼吸内科老年患者医院感染的危险因素,并对制定干预措施,为临床防治提供依据。方法收集2010年1月-2012年6月1028例入住呼吸内科的老年患者,根据其是否发生医院感染分为感染组与非感染组,应用多因素回归分析进行分析。结果 1028例呼吸内科老年患者中有116例发生医院感染,感染率为11.3%,其中呼吸系统感染最多见,占51.7%,以真菌感染居多,占54.2%;感染组长期卧床60例占51.7%,吞咽困难66例占56.9%,侵入性操作64例占55.2%,白蛋白水平(31.2±3.1)g/L,非感染组长期卧床310例占34.0%,吞咽困难400例占43.9%,侵入性操作400例占43.9%,白蛋白水平(40.8±4.1)g/L,两组间比较差异有统计学意义(P<0.05);进一步多因素分析显示,长期卧床、侵入性操作及白蛋白水平低下是呼吸内科老年患者医院感染发生的独立危险因素(P<0.05)。结论呼吸内科老年患者医院感染发生与长期卧床、侵入性操作及白蛋白水平低下存在密切的相关性,是其发生的独立危险因素,在临床工作中对于上述危险因素要积极的给予必要的干预。
OBJECTIVE To discuss risk factors of nosocomial infections in the elderly patients of respiratory medicine department and put forward intervention measures so as to guide the clinical prevention and treatment. METHODS A total of 1028 cases of elderly patients who were treated in the respiratory medicine department were enrolled in the study and were divided into the infection group and the non-infection group, then the multivariate regression analysis of the risk factors was performed. RESULTS Of 1028 cases of elderly patients, the nosoeomial infections occurred in 116 cases with the infection rate of 11. 3%. The respiratory tract infections were most common, which were caused by fungi. In the infection group, there were 60 （51.7%） cases of long-term bedrid- den patients, 66 （56. 9M） cases of dysphagia patients, and 64 （55. 2%） cases of patients undergoing invasive operation, the level of albumin was （31.2 ±3.1） g/L; in the non-infection group, there were 310 （34.0M） cases of long-term bedridden patients, 400 （43.9%） cases of dysphagia patients, and 400 （43.9M） cases of patients undergoing invasive operation, the level of albumin was （40.8±4.1） g/L, the difference between the two groups was statistically significant （P〈0.05）. The multivariate analysis showed that the long-term bedridden, invasive operation, and low level of albumin were the independent risk factors for the nosocomial infections in the elderly patients of the respiratory medicine department （P〈0.05）. CONCLUSION The incidence of nosocomial infections in the elderly patients of the respiratory medicine department is closely related to the long-term bedridden, invasive operation, and low level of albumin, which are the independent risk factors; it is necessary for the hospital to carry out interventions to the risk factors discussed above.
