摘　　要：目的探讨本院4种常见碳青霉烯类耐药革兰氏阴性杆菌(CRO)检出率与抗菌药物使用强度(AUD)的相关性,为降低其耐药性和促进临床合理使用抗菌药物提供参考。方法收集和统计2012—2019年度广西某综合性三级甲等医院住院病区抗菌药物的使用情况,监测4种常见革兰氏阴性杆菌对碳青霉烯耐药率的变迁情况,采用Pearson相关方法分析4种常见CRO检出率与抗菌药物使用强度的相关性。结果2012—2019年4种常见CRO的各年度检出率均无明显变化趋势。其中耐碳青霉烯大肠埃希菌(CRECO)的检出率与莫西沙星、多西环素的使用强度成正相关(P均<0.05);耐碳青霉烯肺炎克雷伯菌(CRKPN)的检出率与环丙沙星的使用强度成负相关(P均<0.05);耐碳青霉烯铜绿假单胞菌(CRPAE)的检出率与亚胺培南和头孢哌酮舒巴坦的使用强度成正相关(P均<0.05),而与环丙沙星的使用强度成负相关(P均<0.05);耐碳青霉鲍曼不动杆菌(CRAB)的检出率与亚胺培南、头孢哌酮舒巴坦和多西环素的使用强度成正相关(P<均0.05)。结论CRO的检出率与抗菌药物使用强度息息相关,临床诊治中需要加强抗菌药物合理使用的管控,减少细菌耐药性的产生,改善不断恶化的临床多重耐药菌或广泛耐药菌感染形势。Objective To determine the correlation between detection rate of 4 common carbapenem-resistant organism(CRO)and antimicrobial use density(AUD)to reduce drug resistance and provide reference for reasonable antibiotics use.Methods AUD of antibacterial drugs commonly used in the inpatient sections of a comprehensive 3A hospital in Guangxi from 2012 to 2019 was collected.The 4 common CROs were constantly monitored,and Pearson correlation was used to analyze the correlation between the dection rate of 4 common CRO and AUD.Results The annual detection rates of 4 common CRO showed no significant change from 2012 to 2019.The detection rate of carbapenem resistant Escherichia coli was positively correlated with the AUD of moxifloxacin and doxycycline(P<0.05).The detection rate of carbapenem resistant Klebsiella pneumoniae was negatively correlated with the AUD of ciprofloxacin(P<0.05).The detection rate of carbapenem resistant Pseudomonas aeruginosa was positive correlated with antimicrobial use density of imipenem and cefoperazone/sulbactam(P<0.05),but negatively with that of ciprofloxacin(P<0.05).The detection rate of carbapenem resistant Acinetobacter baumannii was positively correlated with the AUD of imipenem,cefoperazone/sulbactam and doxycycline(P<0.05).Conclusion The detection rates of CRO are closely related to the AUD.It is necessary to control the use of antibiotics,to reduce antimicrobial resistance.
