Abstract:
Objective To understand the clinical distribution characteristics of Acinetobacter baumannii in our hospital and the change situation of drug resistance rates to provide a basis for the clinical rational drug use and the nosocomial infection manage-ment.Methods The Acinetobacter baumannii strains isolated in our hospital from January 2005 to December 2013 were performed the retrospective analysis on its department distribution,specimen distribution and change of drug resistance rates.Results 964 strains of Acinetobacter baumannii were isolated during these 9 years,in which 713 strains were multi-drug resistant.The isolated strains were less during 2005 -2008,which were 30,26,22,19 strains respectively.The isolated strains began to increase during 2009-2010,which were 65,50 strains respectively.The detection rate began to enormously increase from 2011,which were 157, 229,366 strains respectively from 2011 to 2013.The top three departments of the highest isolation rates during these 9 years were ICU,neurosurgery department and respiratory department.The specimen source was always dominated by the respiratory tract specimens,followed by the secretion samples,in recent years,the detection rates of blood,urine and drainage specimens were in-creased to some extent.The drug resistance rates in 13 kinds of drugs totally showed the increasing trend,the resistance rate of par-tial drugs was decreased to some extent.Conclusion Acinetobacter baumannii easily cause nosocomial infections,which is difficult to be eliminated and has high occurrence in the departments centralized with critical patients.The respiratory infection is the main pathogenic type.Its drug resistance is serious,multi-drug resistant and pan-resistant strains have the higher proportion.Clinic should rationally use the drugs based on the drug susceptibility test results,coordinates with the infection control departments for doing disinfection and isolation well and prevent ing the outbreak of nosocomial infections.
