The authors also suggested that CT lung scan could differentiate VAT from VAP. However, recent guidelines require the presence of new pulmonary infiltrate to diagnose VAP. Therefore, to diagnose a new infiltrate on CT scan, a baseline examination is mandatory. One could wonder whether performing CT scan in all patients at ICU admission to differentiate potential subsequent VAT from VAP would be cost-effective. In addition, intrahospital transport is required because this diagnostic procedure is unrealizable inside the ICU. Intrahospital transport is associated with considerable potential for misadventure and can be a life-threatening endeavor. In addition, a recent case-control study identified intrahospital transport (odds ratio, 2.9; 95% confidence interval, 1.4 to 5.7) as an independent risk factor for VAP.7 The supine position during intrahospital transport, which increases the risk of aspiration of gastric content or of contaminated secretions, and the frequent manipulations of the ventilator circuits needed during intrahospital transport, are well known risk factors for VAP.
