Which practice is essential to reduce infection risk in the NICU?

• A. Strict hand hygiene before touch and after contact with the neonate
• B. Frequent glove changes without hand hygiene
• C. Reusing disposable equipment without disinfection
• D. Limiting isolation precautions to non-neonatal patients

Answer: (A)

Infection prevention in the NICU hinges on keeping hands as free of pathogens as possible, because hands are the primary means by which microbes move between caregivers, the environment, and vulnerable newborns. Strict hand hygiene before touching a neonate and after contact with the neonate breaks that transmission chain at the most common point of contact, drastically reducing infection risk. Using an alcohol-based hand rub is efficient for routine cleaning, but if hands are visibly dirty or after exposure to certain organisms, washing with soap and water is essential. It’s important to remember that gloves do not replace hand hygiene—hand hygiene should occur before donning gloves and after removing them to ensure any contamination from gloves doesn’t transfer to the infant or surroundings.

The other practices fall short because they either bypass the critical step of hand hygiene, risk transferring microbes through contaminated or improperly handled equipment, or ignore the need for appropriate precautions to protect neonates. Reusing disposable equipment without disinfection can spread organisms, and changing gloves without performing hand hygiene gives a false sense of security. Limiting isolation precautions to non-neonatal patients neglects the fact that neonates can harbor and transmit infections as well, requiring appropriate infection control measures across the NICU.
