A large clinical trial presented at ESCMID Global 2026 revealed that enhancing oral hygiene in hospitalized patients significantly reduces non-ventilator-associated hospital-acquired pneumonia (NV-HAP). The study, which involved 8,870 patients across nine wards in Australia, showed an increase in oral care adherence from 15.9% to 61.5% and a 60% drop in NV-HAP cases. Findings emphasize the importance of oral care in preventing infections, especially since NV-HAP often arises from aspirated bacteria from the oral cavity, leading to improved infection control strategies in clinical settings.
