Comparing hand hygiene measures in a neonatal ICU: a randomized crossover trial

Area of Science:

• Healthcare-associated infections
• Infection control
• Neonatal intensive care units

Background:

• Hand hygiene is critical in preventing pathogen transmission in healthcare settings.
• Neonatal intensive care units (NICUs) have vulnerable patient populations requiring stringent infection control measures.
• Evaluating the efficacy of different hand hygiene agents is essential for optimizing patient safety.

Purpose of the Study:

• To compare the effectiveness of plain soap, alcohol hand rub, and iodophors for hand hygiene among nurses in a NICU.
• To determine which hand hygiene agent provides superior microbial reduction on nurses' hands.
• To inform best practices for hand hygiene in high-risk neonatal environments.

Main Methods:

• A randomized, crossover, controlled trial involving 35 NICU nurses.
• Nurses were assigned to plain soap hand washing, alcohol hand rub, or povidone-iodine hand scrub in a crossover design.
• Hand cultures were collected before and after hygiene interventions, with colony-forming unit counts (CFU-C) as the primary outcome.

Main Results:

• Alcohol hand rub and povidone-iodine significantly reduced CFU-C compared to plain soap (P<0.001).
• Median percent reduction in CFU-C was 92% for alcohol and 87% for povidone-iodine, versus 33.3% for plain soap.
• Alcohol and povidone-iodine resulted in a higher proportion of nurses with low CFU-C counts (71% and 72%, respectively) compared to plain soap (47%).

Conclusions:

• Alcohol hand rub and povidone-iodine hand scrubs are more effective than plain soap for hand decontamination in NICU nurses.
• These findings support the use of alcohol-based hand rubs and iodophors for enhanced hand hygiene in neonatal intensive care settings.
• Implementing superior hand hygiene agents can contribute to reducing the risk of infections in vulnerable neonates.
