Neonatal VAP prevention bundles associated with lower infection rates in meta-analysis
A systematic review and meta-analysis of 34 studies involving 6,301 mechanically ventilated neonates found lower ventilator-associated pneumonia rates with prevention bundles and oral care. The authors caution that varied bundle components, non-randomized designs and inconsistent diagnostic criteria limit conclusions about cause and effect.
- Bundles were associated with lower neonatal VAP odds and rates.
- Oral care was associated with lower VAP odds.
- Study designs and bundle components varied.
- Causal effects remain uncertain.
Researchers searched four databases through June 2025 for studies of interventions to prevent ventilator-associated pneumonia (VAP) in mechanically ventilated neonates. The systematic review and meta-analysis included 34 studies and 6,301 neonates; eligible designs included randomized trials, observational studies and quasi-experimental studies. Outcomes included VAP odds and rates adjusted for ventilator-days.
Bundle-based quality-improvement packages were associated with lower VAP odds (OR 0.40, 95% CI 0.28–0.57; I²=37%). In analyses adjusted for mechanical-ventilation exposure, bundles were associated with a lower incidence rate (IRR 0.56, 95% CI 0.43–0.73) and 8.33 fewer cases per 1,000 ventilator-days (95% CI 3.9–12.7 fewer). Oral care was also associated with lower VAP odds (OR 0.53, 95% CI 0.35–0.81).
The findings support further evaluation of bundle-based prevention in neonatal intensive care units, but do not establish that the interventions caused the reductions. Bundles differed in composition, and many included studies were non-randomized. The estimated benefit of oral care is particularly uncertain because of small-study effects, inconsistent subgroup results and variation in VAP diagnostic criteria; evidence for other interventions was limited and heterogeneous.
In practice
For neonatal intensive care teams caring for mechanically ventilated newborns, this synthesis found that bundle-based quality-improvement packages were associated with lower VAP odds and ventilator-day–adjusted rates. The results may inform local evaluation of prevention practices, but they do not establish that bundles themselves caused the reductions: most included evidence was non-randomized, and bundle components varied. Oral care was also associated with lower odds, but the magnitude is uncertain because of small-study effects, inconsistent subgroup findings and varying diagnostic criteria. The findings do not establish a single effective bundle or component.
