我院耐碳青霉烯类革兰氏阴性杆菌检出率与药物消耗量的相关性分析

摘要

目的:为规范临床碳青霉烯类抗菌药物的使用和控制耐药菌感染提供参考.方法:回顾性分析我院2011-2016年3种耐碳青霉烯类革兰氏阴性杆菌的检出情况,并统计碳青霉烯类抗菌药物的消耗量、目标治疗率和用药疗程,采用Pearson检验考察耐药菌检出率与碳青霉烯类抗菌药物消耗量的相关性.结果:2011-2016年,我院共检出耐碳青霉烯类鲍曼不动杆菌(CRAB)1222株、耐碳青霉烯类铜绿假单胞菌(CRPA)655株、耐碳青霉烯类大肠埃希菌(CRE)53株,检出率分别由2011年的23.88%、8.92%、0.09%上升至2016年的80.34%、35.74%、0.97%;我院使用的碳青霉烯类抗菌药物品种主要为亚胺培南和美罗培南,其消耗量分别由4222、145 g上升至7218、4387 g,两者的目标治疗率均低于60%,用药疗程>14 d的患者比例均超过65%.CRAB、CRPA、CRE的检出率与碳青霉烯类抗菌药物的消耗量均呈正相关(r>0.9,P14 d was more than 65%. The detection rates of CRAB,CR-PA and CRE were positively correlated with the consumption of carbapenem antibiotics (r>0.9,P<0.05). CONCLUSIONS:The detection rate of carbapenems-resistant Gram-negative bacillus and drug consumption increase year by year in our hospital,and they have certain correlation. The target cure rate of carbapenem antibiotics in our hospital is in low level,and there is a long treatment course. They are should be standardized in the clinic. The selection of carbapenem antibiotics should be strictly followed clinical in-dications so as to reduce the generation of drug-resistant strains.
