Effectiveness of ventilator bundle in preventing ventilator-associated pneumonia, A quasi-experimental study

Abstract

Background: Ventilator-associated pneumonia (VAP) is a leading cause of morbidity and mortality in intensive care units. This study evaluates the effectiveness of a ventilator bundle in preventing VAP among patients on mechanical ventilation. Materials and Methods: A quasi-experimental study was conducted over one year in the Department of Pulmonary Medicine, Sambhram Institute of Medical Sciences, Kolar, fifty patients were divided into experimental (n=25) and control (n=25) groups. The experimental group received the ventilator bundle, while the control group received routine care. VAP was assessed using the modified Clinical Pulmonary Infection Score. Results: The experimental group exhibited a significant reduction in VAP severity, with 28% showing no infection and only 12% experiencing severe infection compared to 0% and 68% in the control group, respectively. Statistical analysis revealed a significant difference in post-test scores (p ≤ 0.05), confirming the effectiveness of the ventilator bundle. Conclusion: The ventilator bundle significantly reduced the incidence and severity of VAP. Implementing such evidence-based interventions in ICU settings can enhance patient outcomes and reduce healthcare-associated infections.
