Burden of severe infections due to carbapenem-resistant pathogens in intensive care unit

Area of Science:

• Infectious Diseases
• Critical Care Medicine
• Microbiology

Background:

• Intensive care units (ICUs) are epicenters for nosocomial infections, driven by aging populations, comorbidities, and complex surgeries.
• Multidrug-resistant organisms (MDROs) are primary causes of infection in ICUs, leading to high patient mortality.
• Carbapenems, once last-resort antibiotics, are increasingly ineffective due to widespread carbapenem resistance.

Purpose of the Study:

• To review the challenge of carbapenem-resistant MDROs from an intensivist's viewpoint.
• To highlight the epidemiology and definitions of common carbapenem-resistant MDROs.
• To underscore the critical importance of this issue for clinicians.

Main Methods:

• Comprehensive literature review focusing on carbapenem resistance in ICUs.
• Analysis of the epidemiology of key carbapenem-resistant pathogens.
• Discussion of clinical implications from the perspective of critical care physicians.

Main Results:

• Carbapenem resistance, particularly in Gram-negative pathogens, represents a significant global public health threat.
• Common carbapenem-resistant MDROs include Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacterales.
• The increasing prevalence of these resistant organisms complicates infection treatment in ICUs.

Conclusions:

• The rise of carbapenem-resistant MDROs in ICUs demands heightened awareness and clinical vigilance.
• Understanding the epidemiology and characteristics of these pathogens is crucial for effective management.
• Intensivists must be well-informed to combat the growing threat of multidrug resistance.
