Intensive Care Unit Relocation and Its Effect on Multidrug-Resistant Respiratory Microorganisms

Area of Science:

• Infectious Diseases
• Critical Care Medicine
• Hospital Epidemiology

Background:

• Multidrug-resistant (MDR) pathogens in intensive care units (ICUs) are linked to adverse patient outcomes.
• Environmental factors, such as ICU relocation, may influence MDR pathogen transmission.
• The impact of ICU relocation on MDR pathogen detection and patient outcomes requires further investigation.

Purpose of the Study:

• To evaluate the effect of ICU relocation on the detection rates of MDR respiratory pathogens.
• To assess the impact of ICU relocation on patient outcomes, including antibiotic use and hospital stay duration.

Main Methods:

• A retrospective analysis of adult patients admitted to the ICU before and after relocation.
• Comparison of baseline patient characteristics, MDR respiratory pathogen detection rates, antibiotic utilization, and patient outcomes.
• Statistical analysis to determine the significance of observed differences.

Main Results:

• No significant difference in MDR respiratory pathogen detection rates before (90.0 per 1,000 patient-days) and after relocation (68.8 per 1,000 patient-days).
• Significant reduction in colistin use post-relocation (53.5 to 18.7 days).
• Significant decrease in hospital stay duration from 29 to 21 days post-relocation.

Conclusions:

• ICU relocation did not significantly alter MDR respiratory pathogen detection rates.
• ICU relocation may contribute to reduced antibiotic use for MDR pathogens.
• Relocation of the ICU environment appears to improve patient outcomes, including shorter hospital stays.
