Impact of the Ventilator-associated Pneumonia Bundle in a Medical Intensive Care Unit

Purpose: The purpose of this study was to confirm the compliance of the application of a ventilator-associated pneumonia bundle and understand its effects on the decrease in the incidence of ventilator-associated pneumonia. Methods: This was a retrospective observational study with history control group design. Subjects were selected from January to June 2014, prior to the intervention using the ventilator-associated pneumonia bundle. Subjects were also selected from October 2014 to March 2015, 3 months after the intervention. The number of subjects was 112 before the intervention, and 107 after the intervention. Results: The number of nurses who followed the bundles increased from 8 out of 29 (27.6%) before the intervention to 19 out of 29 (65.5%) after the intervention (odd ratio=4.99, confidence interval=1.63-15.25, p=.004). There were 3 cases of ventilator-associated pneumonia before the intervention and 1 case after the intervention. The ventilator days were 2,143 days before the intervention and 2,232 days after the intervention. The ventilator-associated pneumonia rate of the 1,000 ventilator days was 1.40 before the intervention and decreased to 0.45 after the intervention. Conclusion: This study is meaningful, as there has been little research conducted regarding the application of the ventilator-associated pneumonia bundle in South Korea.
