摘要
目的调查老年髋部手术后患者医院感染发生状况及引起感染的危险因素。方法选取2014年8月至2017年6月在我院行老年髋部手术患者358例为研究对象,目标性监测患者术后医院感染状况,引入多因素Logistic回归模型,分析老年髋部术后患者引起医院感染的危险因素。结果术后发生医院感染34例,感染率9. 50%。感染部位以下呼吸道感染率最高,占44. 12%;感染时间以1～3月份感染率最高,占44. 12%。共分离出41株病原菌,其中革兰氏阴性菌27株,革兰氏阳性菌13株,真菌1株。引入多因素Logistic回归模型分析显示,年龄、全麻、糖尿病、低蛋白血症、贫血、尿管插管次数、操作人员手卫生、病房环境、抗菌药物术前预防使用、住院时间是老年髋部手术患者术后医院感染的独立危险因素。结论加强易感高危人群筛查、环境监测与分析,明确术后医院感染危险因素,及时采取有针对性的防控措施,利于降低老年髋部手术患者术后医院感染发生率。
Objective To investigation the nosocomial infection status of elderly patients after a hip surgery and risk factors causing infection. Methods To analyze risk factors causing infection in elderly patients after a hip surgery, research subjects consisting of 358 elderly patients with a hip surgery admitted in our hospital from August 2014 to June 2017 were selected and monitored for conditions of postoperative infection. A multivariate Logistic regression model was introduced to analyze risk factors causing infection in these patients. Results There were 34 postoperative infection cases and the infection rate was 9.50 %. Lower respiratory tract infection rate was the highest, accounting for 44.12%. The infection rate was the highest from January to March, accounting for 44.12%. A total of 41 pathogenic bacteria were isolated, including 27 Gram-negative bacteria, 13 Gram-positive bacteria and 1 fungus. Multivariate Logistic regression model analysis showed that age, general anesthesia, diabetes, hypoproteinemia, anemia, number of catheter intubation, operator hand hygiene, ward environment, preoperative prevention of antibiotics, and the length of hospital stays were independent risk factors for postoperative hospital infection in elderly patients with hip surgery. Conclusion Strengthening the screening of highly susceptible groups and environmental monitoring and analysis, identifying risk factors of postoperative infection and taking timely targeted preventive measures are helpful to reduce the incidence rate of postoperative infection in elderly patients with a hip surgery.
