Factors associated with multidrug-resistant Pseudomonas aeruginosa infection: a hospital-based case-control study
Main Article Content
Abstract
This study aimed to investigate the factors associated with multidrugresistant Pseudomonas aeruginosa (MDR-PA) infection. The study was a hospital-based case-control study. Data were collected from medical records of patients with MDR-PA infection (110 cases) and without MDR-PA infection (110 controls) at the Roi Et Hospital between January 1, 2015 and December 31, 2017. Data analysis used statistics, univariable analysis, and multiple logistic regressions. Statistical significance was set at p-value < 0.05. Most of the 110 cases with MDR-PA infection were male (51.82%) and the mean age was 61.82 ± 15.67 years, while most of the 110 controls were male (56.36%) and the mean age was 55.01 ± 16.09 years. The multivariable analysis revealed that patients aged over 60 years (ORAdj = 2.06, 95%CI = 1.14-3.71), admitted for more than 7 days (ORAdj = 2.43, 95%CI = 1.28-4.60), underwent procedures involving an endotracheal tube (ORAdj = 2.61, 95%CI = 1.42-4.80) and a mechanical ventilator (ORAdj = 3.14, 95%CI = 1.67-5.88). Therefore, the risk factors for MDR-PA infection were patients who were admitted for more than 7 days, who underwent procedures involving an endotracheal tube and a mechanical ventilator.
