目的探讨急诊科患者泌尿感染病原学分布及危险因素,并提出针对性干预措施。方法选取2012年5月至2014年5月688例急诊科患者,统计泌尿感染发生率,检测病原菌分布,对性别、年龄、基础疾病等潜在因素实施单因素及多因素分析,研究危险因素。结果 688例患者经检测,发生泌尿感染79例,占11.5%。从79例患者中分离出86株病原菌,其中大肠埃希菌70株,占81.4%;其中年龄≥60岁、多种抗生素联合使用、近期手术史、基础疾病均是急诊泌尿感染的危险因素;年龄≥60岁(P=0.020,OR=3.527,95%CI=1.54~5.77)、基础疾病(P=0.011,OR=6.227,95%CI=3.85~9.46)是急诊科泌尿感染的独立危险因素。结论急诊科泌尿感染危险因素较多,高龄、合并基础疾病为独立危险因素,同时病原菌耐药机制复杂,临床需积极干预。 Objective To explore the etiological distribution and risk factors of urinary tract infection in emergency department and put forward targeted interventions. Methods A total of 688 emergency department patients from May 2012 to May 2014 were enrolled in this study. The incidence of urinary tract infection was calculated. The distribution of pathogens was detected. Univariate and multivariate analyzes were performed on the potential factors such as gender, age and underlying diseases to study the risk factors. Results 688 patients were tested, urinary infection occurred in 79 cases, accounting for 11.5%. 86 pathogens isolated from 79 patients, of which 70 strains of Escherichia coli, accounting for 81.4%; of which age ≥ 60 years, a combination of multiple antibiotics, the recent surgical history, underlying diseases are the risk factors for emergency urinary tract infection; (P = 0.011, OR = 6.227, 95% CI = 3.85-9.46) were the independent risk factors for urinary tract infection in emergency department at the age of 60 years or older (P = 0.020, OR = 3.527, 95% CI = 1.54-5.75) . Conclusion There are many risk factors for urinary tract infection in emergency department. The advanced age and the underlying diseases are independent risk factors. At the same time, the pathogenic mechanism of drug resistance is complicated and the clinical intervention is needed actively.
