The relationship between the hospital use of various classes of antibiotics and resistance of Escherichia coli to quinolones remains debated. Our aim was to study the relationship between the hospital use of 16 classes of antibacterial agents and the incidence of quinolone-resistant E. coli isolates.
Antibiotic use and resistance data were collected from 36 hospitals. Incident rate ratios (IRR) were assessed using negative binomial regression.
The incidence of quinolone-resistant isolates was independently associated with the consumption of tetracyclines (IRR 1.139, 95% CI 1.030-1.259), first- and second-generation cephalosporins (IRR 1.007, 95% CI 1.002-1.013), third-generation cephalosporins (IRR 1.029, 95% CI 1.010-1.048), and quinolones (IRR 1.007, 95% CI 1.000-1.014). These associations were independent from the type of patient served.
The level of hospital use of quinolones influences the incidence of quinolone resistance in E. coli hospital isolates. The consumption of two other classes of antibiotics, cephalosporins and tetracyclines, is also associated with quinolone resistance.
医院中各类抗生素的使用与大肠杆菌对喹诺酮类药物的耐药性之间的关系仍存在争议。我们的目的是研究 16 类抗菌药物在医院中的使用与喹诺酮类耐药大肠杆菌分离株的发生率之间的关系。
从 36 家医院收集抗生素使用和耐药数据。使用负二项式回归评估发病率比值比（IRR）。
喹诺酮类耐药分离株的发生率与四环素（IRR 1.139，95%CI 1.030-1.259）、第一代和第二代头孢菌素（IRR 1.007，95%CI 1.002-1.013）、第三代头孢菌素（IRR 1.029，95%CI 1.010-1.048）和喹诺酮类药物（IRR 1.007，95%CI 1.000-1.014）的消耗独立相关。这些关联与所服务的患者类型无关。
医院中喹诺酮类药物的使用水平影响大肠杆菌医院分离株中喹诺酮类耐药的发生率。另外两类抗生素，头孢菌素和四环素的消耗也与喹诺酮类耐药有关。
