Nosocomial infections in intensive care wards: a multicenter prospective study

Area of Science:

• Infectious Diseases
• Hospital Epidemiology
• Critical Care Medicine

Background:

• Nosocomial infections pose a significant threat in intensive care units (ICUs).
• Understanding the epidemiology and common causes of these infections is crucial for effective prevention.
• Previous studies highlight variability in infection rates across different healthcare settings.

Purpose of the Study:

• To prospectively analyze the incidence and types of nosocomial infections in ICUs.
• To identify the primary causes and pathogens associated with these infections.
• To evaluate the impact of implementing an infection control nurse on reducing infection rates.

Main Methods:

• A three-year prospective study involving 6,952 patients across nine ICUs.
• Systematic data collection on infection occurrences, types, and suspected causes.
• Analysis of pathogen spectrum and intervention effectiveness through a dedicated infection control nurse.

Main Results:

• Nosocomial infection rates varied widely, ranging from 3% to 27%.
• Common infections included urinary tract infections, sepsis, skin/subcutaneous tissue infections, pneumonia, and wound infections.
• Ventilation pneumonia, venous catheters, wound infections, and urinary tract infections were leading causes of sepsis.
• In one hospital, implementing an infection control nurse led to a reduction in infection rates from 17.2% to 14.3% within one year.

Conclusions:

• Targeted infection control strategies, particularly the role of an infection control nurse, can significantly decrease nosocomial infection rates in ICUs.
• Urinary tract infections and sepsis are prevalent, necessitating focused prevention efforts.
• Continuous monitoring and analysis of infection data are essential for maintaining and improving patient safety in critical care settings.
