[Nosocomial infections in a neonatal unit: surveillance program]

Area of Science:

• Neonatalogy
• Infectious Diseases
• Epidemiology

Context:

• Neonatal intensive care units (NICUs) frequently experience hospital-acquired infections (HAIs).
• Effective surveillance programs are crucial for detecting and preventing HAIs in vulnerable neonates.
• International comparisons are essential for benchmarking NICU infection rates.

Purpose:

• To determine the incidence and distribution of HAIs in a NICU.
• To assess device utilization rates (central catheters, mechanical ventilation, parenteral nutrition, bladder catheters).
• To compare NICU data with international standards, specifically the National Nosocomial Infection Surveillance (NNIS).

Summary:

• A prospective cohort study monitored 1530 infants over three years (2006-2008), recording 138 HAI episodes.
• Overall HAI rate was 6.23 per 1000 patient-days. Central catheter use was 32.3%, with an associated infection rate of 8.6 per 1000 patient-days.
• Infants weighing less than 1000 grams exhibited a significantly higher central catheter-associated infection rate (19.7 per 1000 patient-days), exceeding the 90th percentile.

Impact:

• Identified specific high-risk populations (infants <1000g) for targeted infection control strategies.
• Provides valuable data for refining surveillance and prevention protocols in neonatal care.
• Contributes to the global understanding of HAI epidemiology in neonatal populations.
