Risk factors and clinical outcomes for intensive care unit patients with mul-tidrug-resistant Acinetobacter spp. bacteremia

Area of Science:

• Infectious Diseases
• Critical Care Medicine
• Antimicrobial Resistance

Background:

• Multidrug-resistant (MDR) Acinetobacter species are a global health concern.
• Bacteremia caused by MDR Acinetobacter poses significant challenges in intensive care units (ICUs).
• Understanding clinical features and survival factors is crucial for managing these infections.

Purpose of the Study:

• To analyze clinical characteristics and outcomes of ICU patients with MDR Acinetobacter bacteremia.
• To identify factors influencing 30-day mortality in this patient population.
• To provide evidence for improving patient survival rates.

Main Methods:

• A case-control study involving 164 patients with MDR Acinetobacter bacteremia in Vojvodina Province, Serbia (January 2013–March 2016).
• Retrospective review of medical records to collect demographic and clinical data.
• Logistic regression analysis was employed to determine predictors of 30-day mortality.

Main Results:

• The overall 30-day mortality rate was 48.2% (79 out of 164 patients).
• Independent predictors of 30-day mortality included having two or more co-morbidities, diabetes mellitus, and receiving inappropriate antimicrobial therapy.
• These factors highlight specific patient groups at higher risk.

Conclusions:

• Early and appropriate antimicrobial therapy is critical for improving survival in ICU patients with MDR Acinetobacter bacteremia.
• Particular attention should be given to patients with multiple co-morbidities and diabetes mellitus.
• Optimizing antimicrobial strategies can significantly impact outcomes in critically ill patients.
