BACKGROUND
Acinetobacter baumannii has emerged as an important nosocomial pathogen worldwide. The incidence of these infections has recently begun to increase. The mortality rate associated with these infections is high (bacteremia; 52% , pneumonia: 23%~73%) and multidrug resistance has been reported. For the effective control of multidrug- resistant Acinetobacter baumannii(MDR-AB), the impact of these organisms in clinical practice should be determined. This study compared the clinical characteristics, mortality and morbidity of Acinetobacter nosocomial pneumonia between MDR strain and non-MDR strain. METHODS: From Jan. 1, 2002 to Nov. 1. 2004, 47 adult patients with Acinetobacter nosocomial pneumonia in Chuncheon Sacred Heart Hospital were recruited and analyzed retrospectively. MDR-AB was defined as showing in vitro resistance to all commercially available antibiotics against A. baumannii. RESULTS: There were 47 patients with Acinetobacter nosocomial pneumonia. MDR-AB and non MDR-AB was the cause of the pneumonia in 17 and 30 patients, respectively. Mean age of the former was 69+/-11 years old and the latter was 70+/-13 years old. The mean APCHE II score, ICU days and mortality were not different between the two groups(16.1+/-5.4 vs. 14.9+/-4.8, P=0.43, 25.1+/-13.6 vs. 39.1+/-31.0, P=0.2, 58.8% vs. 40%, P=0.21). CONCLUSION: There are no significant differences in mortality and morbidity between MDR and non-MDR Acinetobacter baumannii. The mortality of the two groups is surprisingly high, therefore proper infection control practices are essential. |
