Ventilator‐associated pneumonia (VAP) is the most frequent hospital‐acquired infection among ventilated patients. A few studies have shown that postural change for common secretion management was effective in preventing VAP. The purpose of this study was to evaluate factors associated with the development of VAP, focusing on the relationship between VAP and postural change. We performed a retrospective observational study on 111 patients who had been admitted to the emergency room of a university hospital between January 2008 and September 2010. VAP developed in 32 patients (28.8%); compared to the patients without VAP, the ones who developed VAP had higher rates of blood transfusion, enteral nutrition, and continuous infusion of muscle relaxant. Multiple logistic regression analysis revealed that a longer duration of mechanical ventilation was independently associated with the development of VAP. An increase in postural change within 24 h of endotracheal intubation tended to increase the risk for VAP. Our results suggest that early‐stage postural change for mechanically ventilated patients may affect the incidence of VAP; therefore, a postural change must be carefully performed in a high‐risk group. Further studies should be conducted to examine whether postural change may be a risk factor for VAP in patients requiring mechanical ventilation.
