Abstract:
BACKGROUND: Acinetobacter bacteremia is an emerging nosocomial infection. We tried to find significant risk factors associated with the prognosis of patients with Acinetobacter bacteremia. METHODS: Retrospective case-control study was designed. The odds ratio estimation and multiple logistic regression for the categorical variables and Mann-Whitney test for the continuous variables were done. RESULTS: From September 1, 1999 to December 31, 2000 there were 25 adult patients with Acinetobacter bacteremia in Ajou University Hospital and 24 patients were confirmed as hospital acquired. The median age and hospital length of stay before bacteremia was 52 years old and 9.5 days respectively. There were 16 male patients. The overall mortality was 45.8 % (11 of 24). Thus there were 11 cases (death) and 13 controls (survival) of mortality. Statistical analysis revealed statistically significant differences between cases and controls in the terms of types of wards, central venous catheter, mechanical ventilation, total parenteral nutrition, and multi-resistant organisms. The multiple logistic regression analysis revealed that the more significant independent factors associated with mortality were mechanical ventilation and multi-resistant organisms. CONCLUSION: Acinetobacter bacteremia is a significant nosocomial infection. Especially mechanical ventilation and multi-resistant organisms were independent risk factors associated with high mortality with Acinetobacter bacteremia.
