Prevention of ventilator-associated pneumonia:a case control study

Abstract

Problem: Ventilator-associated pneumonia (VAP) is an infectious process of the pulmonary parenchyma in individuals undergoing mechanical ventilation (MV). Aim: To compare the prevalence of predictor variables among individuals undergoing MV with VAP with the prevalence observed in individuals under MV who do not have the disease. Method: a case-control study with stratified random sample using the medical records of surgical patients undergoing MV between May 2012 and May 2014. The sizing of discrete and finite samples was calculated to get a representative number of the population to be included in the study. The inclusion criteria for the case group is: adult surgical patients under MV who developed VAP. Control group: adult surgical patients undergoing MV for over 48 hours. Exclusion criteria: patients with community and immunosuppressed pneumonia. The SPSS software will be used for processing the data.
