Enterobacter aerogenes primary bacteremia in pediatric patients

Area of Science:

• Infectious Diseases
• Hospital Epidemiology
• Microbiology

Background:

• Intravenous (IV) fluid administration is a common medical procedure.
• Contamination of IV fluids can lead to serious bloodstream infections.
• Enterobacter aerogenes is an opportunistic pathogen.

Observation:

• Seven cases of Enterobacter aerogenes bacteremia occurred within a five-day period in a pediatric hospital.
• All patients presented with spiking fevers.
• The temporal clustering of cases facilitated rapid identification of the outbreak source.

Findings:

• The bacteremia outbreak was definitively linked to contaminated admixed IV fluids.
• Prompt replacement of the contaminated IV fluids was the primary intervention.
• Intravenous antibiotics were administered to affected patients.

Implications:

• This event underscores the critical importance of adhering to hospital pharmacy best practices for IV solution admixture.
• Minimizing contamination risks in IV fluid preparation is essential for patient safety.
• Enhanced surveillance and quality control in pharmaceutical compounding can prevent similar outbreaks.
