目的探讨老年患者院内感染的危险因素以及预防对策。方法 调查某医院老年住院患者560例,对60例发生院内感染患者临床资料进行调查,分析院内感染的危险因素。结果某医院院内感染感染发生率为10.71%,阻塞性肺疾病院内感染率最高为12.83%,其次为恶性肿瘤10.58%,糖尿病9.26%,脑血管疾病为6.67%,心血管疾病5.13%。感染部位以呼吸道为主(51.67%);泌尿道其次(21.67%)。吸氧、静脉留置针、雾化等侵入性操作的院内感染发生率分别为95.00%。、81.67%和43.33%。病原菌培养以革兰阴性杆菌为主(60.94%)。结论 吸氧、静脉留置针、雾化等侵入性操作是院内感染的主要危险,不同基础疾病发生院内感染率不同,严格规范各类侵入性操作,并加强基础性疾病的治疗和合理使用抗生素,预防减少院内感染的发生。
Objective To explore the risk factors of nosocomial infection in elderly patients and its preventive measures. Methods A total of 560 hospitalized elderly patients in a hospital were investigated. The clinical data of 60 patients with nosocomial infections were investigated. The risk factors of nosocomial infections were analyzed. Results The nosocomial infection rate in a hospital was 10.71%. The highest nosocomial infection rate in obstructive pulmonary disease was 12.83%, followed by malignant tumor 10.58%, diabetes 9.26%, cerebrovascular disease 6.67% and cardiovascular disease 5.13%. The main respiratory tract infection (51.67%); urinary tract followed (21.67%). The incidence of nosocomial infections such as oxygen inhalation, intravenous catheterization and nebulization were 95.00% respectively. , 81.67% and 43.33% respectively. Gram-negative bacilli were the main pathogens (60.94%). Conclusions Inhalation of oxygen, venous indwelling needles and atomization is the main risk of nosocomial infection. Infection rate of nosocomial infections varies with different underlying diseases. Various types of invasive procedures are strictly regulated, and the treatment of basic diseases and the rational use of antibiotics, Prevention reduces the incidence of nosocomial infections.
