Infections in a pediatric intensive care unit

Area of Science:

• Pediatric critical care medicine
• Infectious disease epidemiology
• Hospital-acquired infections

Background:

• Infections pose a significant threat to critically ill children.
• Understanding infection patterns in pediatric intensive care units (PICUs) is crucial for patient outcomes.
• Previous data on infection characteristics in PICUs may be limited.

Purpose of the Study:

• To characterize the epidemiology of all infections in a pediatric intensive care unit (PICU).
• To identify common infection sites, causative pathogens, and acquisition status.
• To determine the impact of infections on patient mortality and outcomes.

Main Methods:

• A retrospective review of all infections in a busy PICU from 1982 to 1984.
• Utilized standard Centers for Disease Control (CDC) criteria for infection definition.
• Data collected included infection site, bacteriology, acquisition status, and patient outcomes.

Main Results:

• 221 infections occurred in 180 of 965 admitted patients (23% infection rate).
• Central nervous system, lower respiratory tract, and genitourinary tract infections were most common (70%).
• Haemophilus influenzae was the most frequent pathogen; Staphylococcus aureus and Klebsiella-Enterobacter-Serratia predominated in PICU-acquired infections. Lower respiratory tract infections had the highest mortality (20.5%).

Conclusions:

• Infections significantly increase mortality risk in PICU patients (approx. 300% higher than overall PICU population).
• PICU-acquired and community-acquired infections had similar mortality rates.
• Findings highlight the importance of infection surveillance and control in PICUs for quality assurance.
