ObjectiveTo understand the distribution characteristics and nosocomial infection of carbapenem-resistant Enterobacteriaceae (CRE) in a general hospital of traditional Chinese medicine, so as to provide the evidence for control and management of multidrug-resistant bacteria.MethodsData of CRE in the first Affiliated Hospital of Anhui University of Traditional Chinese Medicine were analyzed retrospectively from 2014 to 2018.ResultsThe total detection rate of CRE was 10.76%, 5.58%, 15.42%, 12.94% and 16.18% from 2014 to 2018, respectively. The detection rate of CRE showed a gradual upward trend (χ2=29.940, P<0.001). The highest number of CRE isolated from clinical specimens was sputum (355 strains, 63.39%), and the next were urine (98 strains, 17.50%) and secretions (38 strains, 6.79%). CRE isolated from different clinical departments were mainly in Neurosurgery Department (172 stains, 30.71%), Intensive Care Unit (Internal Medicine) (145 strains, 25.89%), Intensive Care Unit (Surgery)(106 strains,18.93%), and other internal medical departments (83 strains, 14.82%). A total of 179 patients developed CRE nosocomial infection in the past 5 years, who were mainly male, and with advanced age, long hospital stay, basic diseases, abnormal immune function and invasive operation. The incidence of hospital infection with CRE from 2014 to 2018 were 0.31‰, 0.38‰, 0.89‰, 0.80‰ and 1.14‰, respectively, which also showed a gradual upward trend (χ2=25.111, P<0.001).ConclusionWith the increasing number of clinically isolated CRE strains and the increasing incidence of nosocomial infection of CRE, effective intervention measures should be taken to prevent and control CRE.
