Distribution and Antimicrobial Resistance Analysis of Blood Culture Isolates at a Chinese National Cardiovascular Regional Medical Center: A 7-Year Retrospective Study
Retrospective study identified high rates of antimicrobial resistance in bloodstream infections, suggesting urgent need for tailored treatment strategies.
Key Points
The study reveals that bloodstream infections are predominantly caused by Gram-positive organisms, highlighting treatment challenges for clinicians.
Among Staphylococcus isolates, methicillin-resistant Staphylococcus aureus accounted for 51.6%, indicating significant drug resistance in the ICU setting.
A total of 1,055 isolates were analyzed from blood cultures, with 31.5% Gram-negative and 62.7% Gram-positive bacterial strains identified.
The alarming carbapenem resistance of K. pneumoniae at 28.8% underscores the need for continuous surveillance and improved infection control measures.
