Ventilator-associated tracheobronchitis (VAT) is a common intensive care unit (ICU)-acquired infection. Its incidence ranges from 1.4 to 19% of critically ill patients receiving invasive mechanical ventilation. This infection is considered as an intermediate process between between colonization and ventilator-associated pneumonia (VAP). 1. To study the incidence of VAT. 2. To study the microbiological profile and anti-microbial susceptibility. This is a prospective study of 149 intubated patients. The endotracheal aspirates were collected and processed. VAT was diagnosed on microbiological and clinical basis. All the relevant clinical details were recorded. An incidence of 24.83% of VAT cases was recorded with male predominance. Various underlying conditions like Cerebrovascular accident, Coronary artery disease, Chronic kidney disease were found to be associated with VAT. Most of them had comorbidities such as hypertension and diabetes mellitus. Acinetobacter baumannii (33.33%), Klebsiella pneumoniae (22.22%), Candida albicans (13.33%) and Staphylococcus aureus (11.11%) were the most frequently encountered pathogens in patients with VAT. The mortality was found to be 18.92%. Patients with VAT experienced longer ICU stay and more prolonged mechanical ventilation compared to patients without VAT. Formulation of a good infection control policy and emphasis on health education will prevent the transmission of multidrug-resistant organisms in the Intensive care units.
