Ambu bag as a source of Acinetobacter baumannii outbreak in an intensive care unit

Area of Science:

• Infectious Diseases
• Critical Care Medicine
• Hospital Epidemiology

Background:

• Intensive care units (ICUs) are high-risk environments for healthcare-associated infections (HAIs).
• Multidrug-resistant Acinetobacter baumannii (MDR-AB) poses a significant threat in critical care settings.
• Rapid identification and control of outbreaks are crucial to prevent patient harm.

Observation:

• An outbreak of Acinetobacter baumannii infections occurred in a tertiary care hospital ICU.
• Three patients were infected concurrently, with a shared Ambu bag identified as the likely transmission source.
• The contaminated Ambu bag facilitated the rapid spread of multidrug-resistant Acinetobacter baumannii.

Findings:

• The source of the outbreak was successfully traced to a single Ambu bag within one week.
• Implementation of control measures and continuous surveillance effectively contained the outbreak.
• No further cases of Acinetobacter baumannii infection were reported in the ICU for six months post-intervention.

Implications:

• Highlights the critical role of environmental hygiene and equipment disinfection in preventing HAIs.
• Demonstrates the effectiveness of prompt source identification and targeted interventions in controlling MDR-AB outbreaks.
• Emphasizes the importance of ongoing surveillance for early detection and management of resistant bacterial infections in ICUs.
