Analysis of clinical distribution and drug resistance of <i>Escherichia coli </i> and <i>Klebsiella pneumoniae</i> in a hospital of Nanjing from 2020 to 2022
Journal Title: Chinese Journal of Clinical Research - Year 2024, Vol 37, Issue 5
Abstract
<b>Objective</b> The clinical distribution and drug resistance of <i>Escherichia coli </i> and<i>Klebsiella pneumoniae </i> in a hospital of Nanjing from 2020 to 2022 were analyzed in order to provide the basis for clinical rational use of antibiotics. <b>Methods</b> The distribution and drug resistance of <i>Escherichia coli </i> and <i>Klebsiella pneumoniae </i> specimens in Zhongda Hospital Southeast University from 2020 to 2022 were retrospectively analyzed.<b>Results</b> A total of 3 507, 4 323 and 4 806 pathogenic bacteria were detected from 2020 to 2022. There were 616, 748 and 840 strains of <i>Escherichia coli </i>, and 456, 631 and 757 strains of <i>Klebsiella pneumoniae </i>, with the total 3-year detection rate of 17.4% and 14.6%. There was a statistically significant difference in the constituent ratio of pathogenic bacteria between 2020 and 2022 (P＜0.01). From 2020 to 2022, the top three samples of pathogenic bacteria were sputum, blood and urine. From 2020 to 2022, the drug resistance rates of <i>Escherichia coli </i> to cefepime, ceftriaxone, cefazolin, gentamicin, ciprofloxacin, levofloxacin and compound trimethoprim were significantly different (P＜0.01). The drug resistance rates of <i>Klebsiella pneumoniae </i> to imipenem, ertapenem, cefepime, ceftriaxone, cefoperazone sulbactam, cefazolin, cefoxitin, piperacillin tazobactam, ampicillin, amikacin, gentamicin, levofloxacin, nitrofurantoin and compound trimethoprim were significantly different (P＜0.01).<b>Conclusion</b> The average detection rate of <i>Escherichia coli </i>and <i>Klebsiella pneumoniae </i> was more than 30% in 2020—2022. The resistance of <i>Escherichia coli </i>and <i>Klebsiella pneumoniae </i> to various antibacterial drugs is statistically different. The clinically targeted drugs need to be selected in strict accordance with the drug sensitivity results.
