Background and Objectives: To assess the rate and incidence density of ventilator-associated pneumonia and to identify the most common etiological agents in the culture of tracheal secretion in an adult intensive care unit. Methods: Descriptive, cross-sectional, retrospective study with a quantitative approach, carried out from January 1st to December 31st, 2014, based on data on rates and incidence density of ventilator-associated pneumonia and isolated microorganisms found in tracheal secretion culture of patients admitted to the adult intensive care unit in a 12-month period. Results: The mean annual rate of ventilator-associated pneumonia was 5.5% and higher rates were found in the second semester. The mean incidence density was 17.97 ventilator-associated pneumonia/1000 patient-days on mechanical ventilation. Nine microorganisms isolated from tracheal secretion culture were identified. The most prevalent pathogens identified in this study were Klebsiella pneumoniae and Pseudomonas aeruginosa. Conclusion: The rate and incidence density of ventilator-associated pneumonia showed a non-expected increase each month for 3 months in a row during the study period. Real time surveillance and incidence oscillation must be valued to adjust sectoral strategies to protect the health of individuals undergoing treatment.
