Background and Objective : Nosocomial blood stream infection is a major problem in hospitals worldwide including Thailand. Infected patients are difficult to treat and have high risk of death. This study aimed to investigate the factors associated with nosocomial bloodstream infection among patients in Intensive Care Unit.
Methods: A hospital-based case-control study (case: control = 1:1) was conducted. All data were collected from medical records of patients in the Intensive Care Unit in Roi Et hospital, Roi Et province between January 1, 2015 and December 31, 2015. The variables of interest were general informations and histories of treatment. Data analyses were descriptive statistics, univariate analysis and multivariate analysis by multiple logistic regressions.
Results: From 91 cases, most of them were males, 52.7 % with the mean age 57.6 +18.9 years whereas 91 controls most of them were males, 56.0% and mean age 55.2 +15.9 years. The top three causes of bacterial septicemias were 28.6% Staphylococcus coagulase negative, 13.2 % P. aeruginosa and 12.1 % A.baumannii. After adjusted for gender and age the statistically significant for patients were admitted at Intensive Care Unit > 7 days (OR adj. = 4.4; 95 %CI: 2.30-8.50), complications (OR adj. = 7.7; 95 %CI: 3.61-14.19), underwent with ventilators (OR adj. = 4.9; 95 %CI: 1.96-12.46) and endotracheal tube (OR adj. = 5.5; 95 %CI: 2.32-13.25).
Conclusion: Admitted for more than 7 days, having complications, endotracheal intubation and having ventilators were factors associated with blood stream infections.
