摘　　要：目的探讨神经内科医院感染的发生率及相关危险因素,以期为神经内科医院感染的预防控制提供参考。方法回顾性分析2011年1月-2013年8月673例住院患者临床资料,分析医院感染率及引起感染的危险因素,采用SPSS16.0统计软件对数据进行统计分析。结果 673例患者中发生医院感染共47例,感染率为6.98%;最常见感染部位依次为呼吸道、泌尿道、皮肤软组织、胃肠道分别占42.55%、23.40%、14.89%、10.64%;年龄≥65岁、春秋冬季、合并≥2种基础疾病、意识昏迷、有吸烟史、机械通气、留置导尿、气管切开、预防使用抗菌药物、住院时间≥15d、脑梗死及脑出血患者医院感染率分别为9.54%、7.98%、8.28%、12.62%、9.91%、8.96%、10.49%、8.45%、8.23%、8.52%、8.16%、8.76%,明显高于无以上情况患者医院感染率(P<0.05)。结论神经内科患者医院感染发生率高,以呼吸道及泌尿道感染最常见,引起医院感染发生的独立危险因素较多,在对患者诊治时要针对性对可能引起医院感染的危险因素进行干预以降低患者医院感染发生率。OBJECTIVE To investigate the incidence of neurology hospital infection and associated risk factors, in order to provide references for neurology hospital infection prevention and control. METHODS A total of 673 cases of hospitalized patients with neurology medical records were retrospectively analyzed for the hospital infection rate and risk factors causing infections. The SPSS 16.0 software was used for data analysis. RESULTS Among 673 patients, there were 47 cases with hospital infections, representing an infection rate of 6.98%. The most common infection parts included respiratory tract, urinary tract, skin soft tissue, gastrointestinal tract and others, accounting for 42.55%, 23.40%, 14.89%, 10.64%, and 8.51%, respectively. Those aged over 65 years, the spring, autumn and winter, combination equal to or higher than 2 basic diseases, unconscious, smoking history, mechanical ventilation, indwelling catheter, tracheotomy, use of antimicrobial agents for prevention, length of hospital stay equal to or over 15 days, cerebral infarction and cerebral hemorrhage patients with hospital infection rates were 9.54%, 7.98%, 8.28%, 12.62%, 9.91%, 8.96%, 10.49%, 8.45%, 8.23%, 8.52%, 8.16%, 8.76%, respectively, significantly higher than those of the patients without the above situation （P%0. 05）. CONCLUSION The neurology patients has high incidence of hospital infections, with respiratory tract and urinary tract infection as the most common infections. There are more independent risk factors causing the hospital infec- tions. In the diagnosis and treatment of patients, it requires to be targeted to intervene hospital infection risk fac- tors so as to reduce the incidence of hospital infections.
