Preterm Infants
Kaufman DA, Blackman A, Conaway MR, Sinkin RA. Nonsterile glove use in addition to hand hygiene to prevent late-onset infection in preterm infants: randomized clinical trial. JAMA Pediatr. Published online August 11, 2014. doi:10.1001/jamapediatrics.2014.953.

• Background– Late-onset infections commonly occur in extremely preterm infants and are
associated with high rates of mortality and neurodevelopmental impairment.
– Hand hygiene alone does not always achieve the desired clean hands, as microorganisms are still present >50% of the time.
– Remaining colony-forming units on hands after hand hygiene may be a significant exposure to preterm infants.
– Some retrospective studies have shown that glove use after hand hygiene may further decrease infections compared with hand hygiene alone.
• Study Objective– To determine if nonsterile glove use after hand hygiene before all patient
and intravenous catheter contact, compared with hand hygiene alone, prevents late-onset infections in preterm infants.
Introduction

• Study Design– Prospective, single-center, randomized clinical trial.– Duration of ≥4 weeks until patient no longer has venous access (central
or peripheral).
• Setting– Neonatal intensive care unit.
• Participants– Birth weight <1000 g and/or gestational age <29 weeks.– <8 days old.– 175 eligible infants, of whom 120 were enrolled.

Methods
• Outcomes– Primary: ≥1 episode of late-onset (>72 hours of age) infection in the
bloodstream, urinary tract, or cerebrospinal fluid or necrotizing enterocolitis.
– Secondary: Infection-related data, mortality, other neonatal morbidities.

Methods
• Limitations
–Single-center study and may be affected by local infection control practices.
–Sample size was based on a higher incidence of infections than were observed in the control group, so it was underpowered for the primary outcome.
–Aim of study was to have >90% compliance with hand hygiene rates.
–Parents had the choice to use gloves or not use gloves if their child was randomized to group A (group with nonsterile glove use after hand hygiene).
–There is a possibility that if hand hygiene, glove use by parents, and study protocol compliance were higher, infection rates may have been lower in 1 or both groups.

Comment
• Nonsterile glove use after hand hygiene prior to patient and catheter contact is associated with fewer gram-positive bloodstream infections (BSIs) and central line–associated bloodstream infections (CLABSIs) in this group of preterm infants.
• Number needed to treat:
– To prevent 1 gram-positive BSI is 6.
– To prevent 1 possible CLABSI is 7.

Comment
• In addition to the Centers for Disease Control and Prevention definition of CLABSI, we also evaluated possible CLABSIs defined as detection of growth from ≥1 blood culture of any organism, including coagulase-negative Staphylococcus, and the presence of a central catheter in the absence of another source.
• We included this definition because asymptomatic BSIs, defined as growth in ≥1 blood culture and treated, even when caused by coagulase-negative Staphylococcus organisms, are associated with increased neurodevelopmental impairment and white matter injury in preterm infants.

• Retrospective studies have demonstrated an association with the addition of glove use after hand hygiene in preterm infants and other patient populations.
– Very low-birth weight infants: Decreased BSIs and necrotizing enterocolitis in preterm infants with birth weight <1500 g; this study had an additional step of applying alcohol hand rub to the gloves.1
– Intensive Care Units: Glove use after hand hygiene during respiratory syncytial virus season compared with the other months during an 8-year period in a children’s hospital was associated with fewer BSIs and CLABSIs in the neonatal intensive care unit, pediatric intensive care unit, and pediatric bone marrow transplant unit.2
