[The current understanding of arterial-catheter related bloodstream infection]

Area of Science:

• Infectious Diseases
• Critical Care Medicine
• Medical Microbiology

Background:

• Catheter-related bloodstream infection (CRBSI) is a severe complication in intensive care units (ICUs).
• Arterial catheter-related bloodstream infection (AC-BSI) is frequently overlooked but occurs at rates comparable to central venous catheter-related bloodstream infections (CVC-BSI).
• AC-BSI contributes significantly to patient morbidity, mortality, and healthcare costs.

Purpose of the Study:

• To review the current research on arterial catheter-related bloodstream infections (AC-BSI).
• To consolidate information on the epidemiology, etiology, pathogenesis, risk factors, diagnosis, treatment, and prevention of AC-BSI.
• To aid clinical decision-making regarding AC-BSI management.

Main Methods:

• Literature review of existing studies on AC-BSI.
• Synthesis of research findings on AC-BSI.
• Analysis of epidemiological data, causative agents, and pathogenic mechanisms.

Main Results:

• AC-BSI incidence is comparable to or higher than CVC-BSI.
• Early detection and intervention, including catheter removal and antibiotic therapy, are vital.
• Prevention strategies are essential for reducing AC-BSI rates.

Conclusions:

• AC-BSI is an underappreciated cause of severe infection in ICUs.
• A comprehensive understanding of AC-BSI is necessary for effective clinical management.
• Further research and adherence to preventive measures can mitigate the impact of AC-BSI.
