Incidence, Etiology and Outcome of Ventilator- Associated Pneumonia in Patients with Percutaneous Tracheotomy

Although the incidence of ventilator-associated pneumonia (VAP) is very high, there are still many uncertainties about clinical course of VAP among tracheotomized patients. Th e goal of the present study was to determine the impact of tracheotomy on VAP incidence and etiology, as well as outcome of VAP patients with tracheotomy. Th e study was conducted in a 15-bed Surgical and Neurosurgical Intensive Care Unit (ICU), Sestre milosrdnice University Hospital Center in Zagreb, Croatia. Th e study included all patients undergoing only percutaneous tracheotomy during the study period. According to our data, the incidence of VAP among percutaneous tracheotomized patients was 42%, not considering the time between tracheotomy and VAP onset. However, when only patients developing VAP after tracheotomy were taken into account, the incidence of VAP among tracheotomized patients dropped to 8% only. Th e most commonly isolated bacterium was Staphylococcus aureus, accounting for 17 (37%) isolates, followed by Haemophilus infl uenzae, accounting for another 10 (22%) isolates. Th e development of VAP among percutaneously tracheotomized patients was associated with longer total ICU stay (regardless of whether VAP developed before or after tracheotomy), while total duration of mechanical ventilation and mortality rate remained unaff ected.
