Abstract
Introduction: The prevalence of Klebsiella pneumoniae has rapidly increased in recent years and the distribution differed greatly by region, We aimed to study the relationship between antibiotic resistance and K. pneumoniae, especially carbapenem-resistant Klebsiella pneumoniae (CRKP) in our tertiary hospitals from 2014 to 2018. Methodology: The antibiotic consumption data of K. pneumoniae were expressed as the defined daily dose (DDD) per 100 inpatient days (DDDs). K. pneumoniae which isolated from clinical samples in hospital between January 2014 and December 2018 were retrospectively analyzed, and the correlation between antibiotic resistance rate and antibiotic frequency was analyzed. Results: From 2014 to 2018, a total of 2295 strains of K. pneumoniae were isolated, with the detection rates of 8.2%, 9.2%, 11.9%, 13.4% and 14.0%. There were 423 strains of CRKP, with the detection rates of 7.5%, 5.8%, 17.8% 24.2% and 25.2% respectively. K. pneumoniae showed different degrees of resistance to antibiotics and showed an increasing trend year by year to carbapenems. The resistance rate of imipenem was 2.5%, 2.8%, 9.9%, 12.3%, 13.4%, and the resistance rate of meropenem was 2.0%, 3.0%, 8.8%, 12.6%, 12.7%, respectively. The resistance rate of most other drugs decreased. The DDDs values of cefoperazone/sulbactam, piperacillin-tazobactam and gentamicin showed a strong positive correlation with K. pneumoniae drug resistance rate (r > 0.8, P 0.05). Conclusions: The detection rate of K. pneumoniae and CRKP increased year by year, which was closely related to the dose of antibiotics. Strengthening the management of antimicrobial drugs and standardising the use of antimicrobial prescriptions were of great significance for delaying the emergence of drug-resistant bacteria.
Highlights
The prevalence of Klebsiella pneumoniae has rapidly increased in recent years and the distribution differed greatly by region, We aimed to study the relationship between antibiotic resistance and K. pneumoniae, especially carbapenem-resistant Klebsiella pneumoniae (CRKP) in our tertiary hospitals from 2014 to 2018
The bacterial resistance rate has been increasing with the widespread use of antibacterial drugs and the rapid change of bacteria, especially carbapenem-resistant K. pneumoniae (CRKP), CHINET data showed that the detection rate of CRKP was 13.8% in 2007 [1], increasing to 25.0% and 26.3% in 2018 [2]
The resistance of K. pneumoniae is mediated by a series of mechanisms, which are mainly related to the widespread use of broad-spectrum antibacterial drugs

This study monitored and analysed the drug resistance of K. pneumoniae in the hospital from January 2014 to December 2018, and at the same time analysed the frequency of use of antimicrobial drugs among inpatients during this period to provide a basis for the rational use of antimicrobial drugs
