The risk of developing a vancomycin-resistant Enterococcus bloodstream infection for colonized patients

Area of Science:

• Infectious Diseases
• Hospital Epidemiology
• Antimicrobial Resistance

Background:

• Healthcare-associated infections (HAIs) affect millions annually in the US.
• Vancomycin-resistant Enterococcus (VRE) is a leading cause of HAIs, transmitted via contaminated surfaces and personnel.
• VRE bloodstream infections (BSIs) are linked to increased mortality, recurrent infections, and substantial hospital costs.

Purpose of the Study:

• To highlight the epidemiology and impact of VRE infections.
• To review current infection control strategies for VRE.
• To emphasize the importance of VRE prevention in healthcare settings.

Main Methods:

• Review of epidemiological data on VRE prevalence and outcomes.
• Summary of established infection control practices for VRE.
• Discussion of risk factors associated with VRE colonization and infection.

Main Results:

• VRE BSIs significantly increase patient morbidity, mortality, and healthcare expenditures.
• VRE transmission is primarily associated with healthcare worker contact and environmental contamination.
• Emerging reports of vancomycin-resistant Staphylococcus aureus underscore the broader threat of antimicrobial resistance.

Conclusions:

• Implementing robust infection control measures, including antibiotic stewardship and contact precautions, is essential for VRE prevention.
• Adherence to central venous line bundles can reduce healthcare-associated BSIs.
• Controlling VRE colonization and infection is vital for reducing patient harm and healthcare costs.
