To assess approaches for preventing ventilator-associated pneumonia (VAP) in mechanically ventilated neonates.
Approach:
Evidence reviewed: Researchers from Qatar examined findings from 34 earlier investigations involving 6,301 neonates receiving mechanical ventilation.
Interventions: The review examined VAP-prevention bundles and oral care. Bundles commonly included hand hygiene, head-of-bed elevation, sterile airway management involving close suction, reduced ventilator-circuit changes, and daily assessments of readiness to wean. Some also included targeted oral-care protocols and environmental or workflow modifications intended to decrease opportunities for transmission.
Key Findings:
Bundle-based quality-improvement packages had the greatest likelihood of reducing VAP.
Compared with controls, bundles were associated with 60% lower odds of VAP and an absolute reduction of 8.33 cases per 1,000 mechanical ventilation-days.
Oral care was associated with lower odds of VAP, but small study sizes limited confidence in this finding.
Interpretation:
Because bundle components varied, the pooled estimates reflect heterogeneous multicomponent packages and cannot be attributed to any single preventive measure.
Limitations:
Bundle components differed across studies.
Small study sizes limited confidence in the oral-care finding.
Conclusion:
The authors recommended future multicenter studies use standardized VAP definitions, stronger controlled designs, transparent reporting of intervention components and implementation fidelity, and consistent ventilator-day-adjusted outcomes.
