Multidrug Resistance in Intensive Care Units: Transmission, Risk Factors, Clinical Outcomes, and the Egyptian Context

Abstract

Background: The burden of MDR infections is substantial, with millions of deaths globally associated with antimicrobial resistance, including a significant proportion directly attributable to drug-resistant pathogens. Critically ill patients are especially vulnerable due to the frequent use of invasive devices, prolonged hospitalization, mechanical ventilation, and repeated exposure to broad-spectrum antimicrobial agents.

Aim: Considering the different effectiveness of prevention strategies for specific bacterial species, further exploration is needed to determine the most effective measures to prevent the acquisition and spread of MDR bacterial colonization.

Conclusion: Given the high prevalence and clinical impact of MDR and XDR infections in ICUs, strict infection prevention and control measures are essential. In-hospital surveillance programs, staff education, antimicrobial stewardship, and routine inspections play a critical role in limiting the spread of resistant organisms and preserving the effectiveness of existing antibiotics.
