Objective:

To evaluate the impact of improved oral hygiene on the incidence of non-ventilator-associated hospital-acquired pneumonia (NV-HAP) in hospital patients.

Approach:

Key Findings:

• The proportion of patients receiving oral hygiene increased from 15.9% to 61.5%.
• NV-HAP cases decreased from 1.00 to 0.41 per 100 admission days at risk, representing a 60% reduction.

Interpretation:

Improving oral hygiene may significantly reduce the risk of NV-HAP by decreasing the microbial burden in the oral cavity, which is a source of aspiration pneumonia.

Limitations:

• Diagnosis of NV-HAP can be challenging due to non-specific symptoms, particularly in older or medically complex patients.
• The study's findings may not be generalizable to all hospital settings.

Conclusion:

Routine oral hygiene practices can play a crucial role in preventing hospital-acquired infections, warranting consistent implementation and monitoring in clinical settings.
