BackgroundVentilator-associated pneumonia (VAP) is a nosocomial pneumonia that develops in patients on mechanical ventilation for >or=48 hours. VAP develops at an estimated rate of 1% to 3% per day of mechanical ventilation.MethodsQuality improvement project. Mechanically ventilated patients received the following oral care every 4 hours: the teeth were brushed with cetylpyridinium chloride (changed to 0.12% chlorhexidine gluconate in 2007) using a suction toothbrush, the oral cavity was cleansed with suction swabs treated with hydrogen peroxide, a mouth moisturizer was applied, deep oropharyngeal suctioning was performed, and suction catheters were used to control secretions. The primary efficacy variable was a diagnosis of VAP in patients mechanically ventilated for >or=48 hours.ResultsThe historical average rate of VAP in 2004 was 12.6 cases/1000 ventilator-days. After the inception of the quality improvement project, VAP rates decreased to 4.12 (VAP cases/days of ventilation x 1000) for May to December 2005, to 3.57 for 2006, and to 1.3 for 2007.ConclusionThe use of an oral care protocol intervention and ventilator bundle led to an 89.7% reduction in the VAP rate in mechanically ventilated patients from 2004 to 2007.
