Abstract:
Objective To investigate the change trend and the drug resistance rate of the multi-resistant organisms in the hospi-tal during the past four years,so as to guide the clinical medication,and strengthen the management of antibiotics application.Meth-ods Kirby-Bauer test which was recommended by the clinical and laboratory standards institute was used to conduct the suscepti-bility test,with the results evaluated based on US Clinical and Laboratory Standards Institute.Results Strains of bacteria were de-tected from January 201 1 to December 2014 in each year for the basic trend.The gram-negative bacterium was in the dominant posi-tion.The bacteria in the top five were:Escherichia coli,Staphylococcus epidermidis,Staphylococcus aureus,Pseudomonas aeruginosa and Pneumonia crayresearch coli.In each year,the overall situation of bacteria distribution had little changed.From the antimicrobial susceptibility test results,425 strains of multi-resistant bacteria were detected during the past four years.The detection rate and constituent ratio of multi-resistant bacteria then fell slightly in the first three years,but rebound in 2014.There was no statistically significant difference between the four years.Conclusion In the past four years,our hospital actively participates in monitoring and controlling the multiple drug-resistant bacteria,but nosocomial infection of the multiple drug-resistant bacteria has not been effec-tively controlled because of a variety of factors.We should continue to strengthen monitoring the clinical multiple drug-resistant bacteria,and understand the change tendency.In order to strengthen the management of the use of antibiotics and to guide clinical rational drug use,the drug sensitive test and the resistance situation of the hospital should be considered for the reasonable selection of antimicrobial agents.Strengthening the biological monitoring of clinical departments,enhancing the consciousness of sterile oper-ation of clinicians can help prevent the spread of drug-resistant strains.
