A scientific research paper recently published explores the species distribution, clinical prevalence, and antimicrobial profiles of Carbapenem-Resistant Enterobacterales (CRE) within a tertiary hospital over a period of two years. The main objective of this retrospective analysis was to serve as a reference guide for clinical anti-infection strategies and hospital infection control measures. Key areas examined include commonly used antibiotics, carbapenemase phenotypes, and resistance profiles.
The analysis identified 239 distinct CRE strains isolated from inpatient samples over the two-year period, with Klebsiella pneumoniae, Escherichia coli, and Proteus mirabilis constituting the primary CRE species. A large majority of these strains were predominantly found in sputum, urine, and blood samples, mainly from the intensive care unit (ICU), geriatrics, and respiratory medicine departments.
Disturbingly, among the 239 CRE isolates, a notably high resistance rate to cephalosporins, enzyme inhibitor combinations, aminoglycosides, and quinolones was found, exceeding 85%, with carbapenems showing a resistance rate of over 90%. However, the resistance rates to tigecycline, ceftazidime/avibactam, and polymyxin B were relatively lower at 1.26%, 24.24%, and 5.43%, respectively. A closer look revealed that 74.06% of the strains produced class A serine carbapenemases, specifically of the KPC type.
It’s evident that the trends of CRE isolation and resistance rates within this hospital align with the international trends, both displaying an upward movement. Such findings underscore the urgency for hospitals to enhance their monitoring of CRE resistance to strengthen their infection prevention, control, and clinical management capabilities.
CRE infections pose a significant challenge due to their resistance to multiple drugs, necessitating rigorous surveillance and efficient strategies to combat their spread. The prevalence of CRE is a critical issue, with the World Health Organization classifying CRE as a top-tier, critical antibiotic-resistant pathogen. Monitoring and addressing CRE trends has profound implications for public health, increasing the burden on patients while extending their hospitalization periods.
Given this critical situation, this study’s findings provide a crucial reference point for rolling out necessary measures for infection control and determining efficient clinical anti-infection strategies, thereby serving as a valuable resource for other medical institutions aiming to prioritize and enhance their infection prevention and control of CRE infections.
