Infection Prevention and Control Strategies According to the Type of Multidrug-Resistant Bacteria and Candida auris...

Area of Science:

• Infectious Diseases
• Critical Care Medicine
• Public Health

Background:

• Multidrug-resistant organism (MDRO) outbreaks are increasing in intensive care units (ICUs).
• Healthcare institutions and workers (HCWs) lack consensus on implementing infection prevention and control (IPC) strategies.
• Existing research often focuses on specific pathogens, hindering a holistic approach to MDRO control.

Purpose of the Study:

• To provide a pragmatic, physician-oriented overview of IPC strategies for various MDRO outbreaks in ICUs.
• To synthesize current knowledge on factors influencing IPC effectiveness in ICUs.
• To identify gaps and suggest future directions for MDRO control in critical care settings.

Main Methods:

• A narrative review of infection prevention and control (IPC) strategies in ICUs.
• Investigation of key elements including patient-to-staff ratios, HCW education, isolation, decolonization, screening, hygiene, outbreak reporting, cost-effectiveness, and reproduction numbers (R0).

Main Results:

• The optimal IPC strategy for MDROs in ICUs remains undetermined.
• IPC strategies are generally cost-effective across different settings and pathogens.
• A standardized protocol for HCW education and a rapid outbreak recognition tool are recommended.
• Further research is needed on MDRO decolonization, and novel strategies like genetic engineering and phage therapy show future promise.

Conclusions:

• Standardized HCW education and rapid outbreak detection tools are crucial for managing MDROs in ICUs.
• ICUs remain significant reservoirs for MDROs due to inconsistent IPC strategy application.
• Emerging technologies may offer future solutions for MDRO control in critical care environments.
