Risk Factor Analysis of Pan-drug Resistant Acinetobacter baumannii-induced Ventilator-associated Pneumonia in ICU

Abstract

This study was to investigate the risk factors of ventilator-associated pneumonia caused by pan-drug resistant Acinetobacter baumannii in emergency intensive care unit so as to provide related basis for clinical prevention. A total of 105 intensive care unit patients, who were treated with ventilator over 48 h in the First Affiliated Hospital of Anhui Medical University and developed Acinetobacter baumannii-induced ventilator-associated pneumonia from January 2017 to December 2018 were enrolled in this study, including 70 cases with pan-drug resistant Acinetobacter baumannii infection served as the pan-drug resistant group and 35 cases with non-pan-drug resistant Acinetobacter baumannii infection served as the control group. The univariate analysis and Logistic regression method were used to explore the risk factors of ventilator-associated pneumonia caused by pan-drug resistant Acinetobacter baumannii. The result of univariate analysis showed that the risk factors of pan-drug resistant Acinetobacter baumannii-induced ventilator-associated pneumonia included tracheotomy, enteral nutrition, the use of carbapenems and use of more than 3 antibiotics before infection. Logistic regression analysis showed that enteral nutrition and the use of carbapenems were independent risk factors of pan-drug resistant Acinetobacter baumannii-induced ventilator-associated pneumonia. In conclusion, enteral malnutrition and the use of carbapenems were the two significant risk factors for pan-drug resistant Acinetobacter baumannii-induced ventilator-associated pneumonia, which are necessary to take active preventive measures in clinical practice.
