我院2006-2010年抗菌药物用量与大肠埃希菌耐药的相关性分析

Correlation of Antibacterials Consumption and Drug Resistance of Escherichia coli in Our Hospital from 2006 to 2010

目的:了解我院大肠埃希菌耐药性的现状和变迁,探讨其发展与抗菌药物用量之间的关系,为抗菌药物管理提供依据。方法:采用回顾性调查方法,计算13种抗菌药物平均每日每百张床位所消耗的用药频度(DDDs)及同期大肠埃希菌的耐药率,用SPSS17.0统计软件对抗菌药物用量与耐药率进行相关性分析。结果:高档次的抗菌药物用量逐年增长,低档次的抗菌药物用量逐年缩减。大肠埃希菌对多种抗菌药物呈广泛耐药,且逐年增长。庆大霉素、氨苄西林、哌拉西林/舒巴坦、头孢唑林、头孢呋辛、头孢西丁、头孢曲松、头孢他啶、环丙沙星、左氧氟沙星、亚胺培南/西司他丁的用量与大肠埃希菌对阿米卡星、庆大霉素、氨苄西林、头孢唑林、头孢呋辛、头孢西丁、头孢噻肟、头孢他啶的耐药率呈不同程度的相关性。结论:大肠埃希菌对多种抗菌药物耐药率高,抗菌药物使用量与大肠埃希菌耐药水平之间存在相关性;应加强细菌耐药监测和抗菌药物临床应用管理。

OBJECTIVE：To explore the change of drug resistance of Escherichia coli and explore the relation between its development and antibacterials consumption to provide reference for antibacterials management. METHODS： Retrospective review was used to calculate the DDDs of 13 kinds of antibacterialsper 100 persons per day and resistant rate of Escherichia coli. The correlation of antibacterials consumption and drug resistance was analyzed by SPSS 17.0 software. RESULTS： Consumption of expensive antibacterials increased year by year, contrary to ordinary ones. Drug resistance of Escherichia coli to various antibacterials also increased year by year. The consumptions of gentamycin, ampicillin, piperacillin/sulbactam, cefazolin, cefuroxime, cefoxitin, ceftriaxome, ceftazidime, ciprofloxacin, levofloxacin and imipenem/cilastin were related to the drug resistance of Escherichia coli to amikacin, gentamycin, ampicillin, cefazolin, cefuroxime, cefoxitin, cefotaxime and ceftazidime in varying degree. CONCLUSION： High resistance rate has been found in Escherichia coli to various antibacterials. Antibacterials consumption is related to drug resistance of Escherichia coli.
