Prevention of Infection in Intensive Care Unit

- Introduction

The Critical Importance of ICU Infection Control

Intensive Care Units (ICUs) are epicenters for managing critically ill patients who are uniquely vulnerable to healthcare-associated infections (HAIs). ICU patients face a 5–10 times greater risk of HAIs compared to general ward patients due to a confluence of factors:

·  Patient Vulnerabilities: Underlying immunocompromising conditions (e.g., diabetes, immunosuppression) and frequent, prolonged antibiotic use.

·  Invasive Devices: Ventilators, central lines, and urinary catheters breach natural anatomical barriers.

·  Environmental & Operational Factors: High concentration of high-touch surfaces, frequent staff-patient interactions, and potential for understaffing or overcrowding.

Consequently, approximately 30% of all HAIs in high-income countries occur in ICUs, significantly increasing patient morbidity, mortality, and healthcare costs.
