Abstract:
Antibiotic resistance among gram-negative pathogens is a world-wide problem that poses a constant threat to patients in the intensive care unit and a therapeutic challenge for the intensivist. Furthermore, the substantial economic burden and increased mortality associated with infections due to highly resistant gram-negative pathogens exacerbate these challenges. Understanding the mechanisms, epidemiology, and risk factors for these infections is paramount to the successful control of outbreaks and for guiding therapy which often entails use of antibiotics with suboptimal efficacy and/or toxicity profiles. In this review we will discuss the global epidemiology, burden, risk factors, and treatment of highly resistant gram-negative infections as they apply to the intensive care population.
Insights
Highly resistant gram-negative infections threaten intensive care unit patients globally. Understanding their epidemiology and risk factors is crucial for effective treatment and control.
Area of Science:
- Infectious Diseases
- Critical Care Medicine
- Microbiology
Background:
- Antibiotic resistance in gram-negative pathogens is a significant global health issue.
- These infections pose a severe threat to intensive care unit (ICU) patients, increasing mortality and healthcare costs.
- Therapeutic options are often limited, with antibiotics having suboptimal efficacy or toxicity.
Purpose of the Study:
- To review the global epidemiology of highly resistant gram-negative infections in the ICU.
- To discuss the associated burden, risk factors, and current treatment strategies.
- To provide insights for controlling outbreaks and guiding clinical management.
Main Methods:
- This is a review article.
- Literature search on global epidemiology, risk factors, and treatment of highly resistant gram-negative infections in ICUs.
- Synthesis of current knowledge and clinical data.
Main Results:
- Highly resistant gram-negative pathogens are a growing concern in ICUs worldwide.
- Infections lead to increased mortality, prolonged hospital stays, and substantial economic burden.
- Risk factors include prior antibiotic exposure, comorbidities, and device use.
Conclusions:
- Effective control requires a thorough understanding of resistance mechanisms and epidemiology.
- Therapeutic strategies must balance efficacy with toxicity, often necessitating novel approaches.
- Multidisciplinary efforts are essential to combat this escalating global challenge.
