  • Drug resistance surveillance of Enterobacteriaceae in West China Hospital of Sichuan University from 2006 to 2015

    ObjectiveTo analyze the distribution and drug resistance of Enterobacteriaceae in West China Hospital of Sichuan University, to provide long-term monitoring data references for clinical practice.MethodsThe clinical information of non-repetitive Enterobacteriaceae isolates from 2006 to 2015 was collected and analyzed. All the isolates were identified by VITEK-2 Compact Automatic Microbial Identification Analyzer (Bio Merieux, France). The statistic informations were analyzed by WHONET 5.6 and iLabDataforMDR 1.03.ResultsA total of 38 487 strains of Enterobacteriaceae were isolated from 2006 to 2015, mainly including 14 862 stains of Escherichia (38.6%), 12 894 stains of Klebsiella (33.5%), 6 277 stains of Enterobacter (16.3%), 1 758 stains of Proteus (4.6%), 1 257 stains of Serratia (3.3%), 933 stains of Citrobacter (2.4%), and 506 stains of Morganella (1.3%). The top three sample types were sputum (46.9%), urine (18.7%), and secretions (11.5%). The drug resistance rate of Enterobacteriaceae showed a downward trend to most antibacterials. The average resistance rate of Enterobacteriaceae to ampicillin, ampicillin/sulbactam, and cefazolin was 85.3%, 52.6%, and 72.9%, respectively. The resistance rates to ceftriaxone, cefepime, gentamicin, and tobramycin were significantly reduced. The resistance rates to other antibiotics showed decreasing or slow increasing trends. The isolation rate of extended-spectrum β-lactamases (ESBL)-producing strains in Escherichia did not change, but the rate in Klebsiella decreased significantly. The isolation rate of multidrug-resistant organisms (MDRO) showed a slow decrease.ConclusionsThe overall antimicrobial resistance and the isolation rates of MDRO and ESBL-producing organisms showed a downward trend in investigating period. However, the carbapenem-resistant Enterobacteriaceae was rising continuously. Long-term monitoring of drug resistance is of notable value to antibiotic management policies.
