The most accepted definition includes fever temperature 38 C new or increased sputum production a microbiologically positive respiratory sample with counts above the accepted thresholds and absence of pulmonary infiltrates on chest X-ray. Although we have no doubt that this pathologic process exists the main controversy lies on whether this entity has any impact on the outcome and thus a specific therapeutic approach is suitable. We will discuss the strengths and drawbacks of the article on this topic published in this issue by Nseir et al. Ventilator-associated tracheobronchitis VAT is a difficult entity to define. Indeed the recently published American Thoracic Society Infectious Diseases Society of America guidelines 1 do not address this issue. VAT is defined as the presence of fever temperature 38 C new or increased sputum production a microbiologically positive respiratory sample with counts above accepted thresholds and absence of pulmonary infiltrates on chest radiography. The apparent crude incidence of VAT ranges from 3 to 10 2 but it is very difficult to determine the exact
