目的分析泌尿外科患者发生医院感染的相关因素。方法以河南省柘城县人民医院泌尿外科收治的178例患者为研究对象,根据患者发生医院感染与否将其分为感染组62例,未感染组116例。采用回顾性调查法分别调查两组患者的病历资料;以患者发生医院感染为因变量,以可能导致患者发生医院感染的各类因素为自变量,进行单因素分析后再进行Logistic多因素分析。结果单因素分析结果显示,与未感染组比较,合并医院感染组患者的平均年龄较大,尿管留置时间较长,合并基础疾病种类≥3种者比例较高,住院时间较长,使用抗菌药物者比例较高,有创诊治措施实施者比例较高,差异均有统计学意义(P均<0.05)。Logistic多因素回归分析结果显示,尿管留置时间、住院时间、使用抗菌药物及实施有创诊治措施为泌尿外科患者发生医院感染的独立危险因素(P<0.05)。结论尿管留置时间较长、住院时间、较长使用抗菌药物及实施有创诊治措施易增加泌尿外科患者发生医院感染的风险,临床上通过对这些因素的综合防治利于降低泌尿外科医院感染发生率。
Objective To analyze the related factors of nosocomial infection in urological patients. Methods A total of 178 patients admitted to Department of Urology, People’s Hospital of Tancheng County, Henan Province were selected as the study subjects. According to whether hospital infection occurred or not, 62 patients were divided into infected group and 116 uninfected patients. The patients’ nosocomial infection was taken as the dependent variable, and various factors that could lead to nosocomial infection were used as independent variables. Univariate analysis and Logistic multivariate analysis were used to analyze the medical records of the two groups. Results The results of univariate analysis showed that the average age of patients with combined hospital infection was longer than that of uninfected patients and the duration of catheter indwelling was longer than that of uninfected patients. The proportion of patients with more than 3 kinds of basic diseases was higher, the length of hospital stay was longer, The proportion of drug users was higher, and the percentage of patients with invasive diagnosis and treatment measures was higher, with significant difference (P <0.05). Logistic multivariate regression analysis showed that catheter indwelling time, length of hospital stay, use of antibacterials and implementation of invasive procedures were independent risk factors for nosocomial infections in urologic patients (P <0.05). Conclusions Long catheterization, length of hospital stay, prolonged use of antibacterials and invasive diagnosis and treatment may increase the risk of nosocomial infections in urological patients. Clinically, the comprehensive prevention and treatment of these factors is conducive to reducing the incidence of nosocomial infections in urology .
