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.
ObjectiveTo study the direct economic burden of hospitalization in patients with carbapenem-resistant Enterobacteriaceae (CRE) infection.MethodsPatients with CRE detected in Jianyang People’s Hospital between January 2017 and June 2019 were divided into infection group and colonization group, and multiple linear regression analysis was used to analyze the confounding factors, and then propensity score matching method was used to match the confounding factors of the two groups, finally the direct economic burden of hospitalization was compared between the two groups.ResultsA total of 2 013 patients were enrolled, including 507 CRE-infected patients and 1 506 CRE-colonized patients. Multiple linear regression results showed that factors affecting the direct economic burden of hospitalization included mechanical ventilation, intravenous catheterization, blood transfusion or use of blood products, urinary intubation, tracheotomy, gender, surgery, intensive care unit stay, main diagnosis, and the type of medical insurance, together with CRE infection (P<0.05). After propensity score matching, these confounding factors were well balanced between the infection group (n=249) and the colonization group (n=249), and the differences were not statistically significant (P>0.05). The median of total hospitalization cost of CRE-infected patients was 1.29 times (15 589.23 yuan more than) that of CRE-colonized patients and the difference between the two groups was statistically significant (Z=–3.116, P=0.002). The top two types of hospitalization cost with largest differences in the medians were the cost of Western medicine (4 850.21 yuan; Z=–3.460, P=0.001) and the cost of laboratory diagnosis (2 613.00 yuan; Z=–3.529, P<0.001), respectively. The cost of antimicrobial drugs differed significantly between the two groups (Z=–3.391, P=0.001), and it was 1.54 times in patients with CRE infection what it was in patients with CRE colonization.ConclusionsThere are many factors affecting the direct economic burden of inpatients, and it is necessary to avoid the influence of confounding factors as far as possible during analysis. The economic burden of patients with CRE infection is significantly greater than that of CRE-colonized patients, so active measures should be adopted to prevent and control CRE infection.
ObjectiveTo evaluate the burden of carbapenem-resistant Klebsiella pneumoniae (CRKPN) and carbapenem-resistant Escherichia coli (CRECO), two types of carbapenem-resistant Enterobacteriaceae (CRE), in pediatric patients in Jiangxi Province.MethodsA retrospective investigation was carried out for the distribution of CRKPN/CRECO in pediatric (neonatal group and non-neonatal group) and adult patients in 30 hospitals in Jiangxi Province from January 2016 to December 2018, and the changing trends and detection situations of different patients and types of hospitals were compared and analyzed.ResultsFrom 2016 to 2018, the annual resistance rates of Klebsiella pneumoniae and Escherichia coli to carbapenem in pediatric patients were 5.89%, 4.03%, and 4.24%, respectively, showed a downward trend (χ2trend=5.568, P=0.018). The resistance rate of Klebsiellae pneumoniae and Escherichia coli to carbapenem in neonatal group was higher than that in non-neonatal group (8.44% vs. 3.40%; χ2=63.155, P<0.001) and adult group (8.44% vs. 3.45%; χ2=97.633, P<0.001). In pediatric patients, the 3-year carbapenem resistance rate of Klebsiella pneumoniae was higher than that of Escherichia coli (9.10% vs. 2.48%; χ2=128.177, P<0.001). In non-neonatal pediatric patients, the 3-year resistance rate of Klebsiella pneumoniae and Escherichia coli to carbapenem in maternity and children hospitals was higher than that in general hospitals (4.35% vs. 1.36%; χ2=25.930, P<0.001). CRKPN/CRECO detected in pediatrics were mainly isolated from sputum (31.64%), blood (24.36%), urine (13.82%), and pus (8.36%).ConclusionAlthough the overall resistance rate of Klebsiella pneumoniae and Escherichia coli to carbapenem in pediatric patients showed a downward trend, that in neonatal patients was still high, and the monitoring and prevention and control measures of CRE should be strengthened in neonatal patients.
