SUMMARY
Introduction: Ventilator-Associated Pneumonia (VAP) is a frequent infection in patients admitted to intensive care units. The occurrence of VAP prolongs hospital stay and increases health care costs. The objective of this study is to assess adherence of health professionals to a VAP prevention package of interventions (Bundle). Outline: Retrospective, documentary study performed in an intensive care unit of a university hospital. The sample consisted of patients hospitalized in the period from January to June 2014, who met the inclusion criteria. The data collection was carried out through examination of medical records. Results: Increase in hospital stay of patients with VAP and low adherence to Bundle items were verified. Proper cuff pressure and oral hygiene with standardized antiseptic were the items with lower adherence. Implications: The adherence to some Bundle VAP prevention measures was not different between groups of patients (with or without VAP) and showed low values of adherence.
