Infection Control Strategies for Multidrug-Resistant Acinetobacter baumannii in Intensive Care Settings
Summary
Multidrug-Resistant Acinetobacter baumannii (MDR-AB) represents a persistent threat in intensive care units (ICUs), where vulnerable patients and invasive devices underpin rapid transmission. Effective infection control demands a multifaceted approach encompassing rigorous hand hygiene, contact precautions, environmental cleaning and active surveillance. Enhanced environmental decontamination protocols target both high-touch surfaces and medical equipment reservoirs, while antimicrobial stewardship curtails selective pressure favouring resistant strains. Molecular typing and whole-genome sequencing facilitate real-time cluster investigation, enabling the rapid identification of outbreak sources and transmission routes. Decolonisation strategies and cohorting of colonised patients further limit cross-infection. Integration of these measures into a coherent infection control programme has demonstrated sustained reductions in MDR-AB incidence and decreased reliance on last-line antibiotics, underscoring the global importance of adaptive, evidence-based policies in critical care environments.

The graph below shows the total number of articles in infection control strategies for multidrug-resistant acinetobacter baumannii in intensive care settings across all publications each year (not limited to Nature Index journals).
Technical terms
Multidrug-Resistant (MDR) Acinetobacter baumannii: Bacterial strains resistant to three or more classes of antibiotics, complicating treatment.
Carbapenem-Resistant Acinetobacter baumannii (CRAB): Subset of MDR-AB harbouring carbapenemase enzymes that inactivate carbapenem antibiotics.
Contact Precautions: Infection control measures including gown and glove use to prevent pathogen spread via direct or indirect contact.
Active Surveillance: Systematic screening of patients or environments to detect colonisation before clinical infection emerges.
Whole-Genome Sequencing (WGS): Comprehensive genetic analysis used to track transmission pathways and identify resistance determinants.
Cohorting: Grouping colonised or infected patients together to minimise cross-transmission to uncolonised individuals.
