Purpose: Acinetobacter was known as a saprophytic colonizer, yet it is considered an important etiologic agent which is isolated from hospital-acquired infections. In this study, we aimed to investigate fatality rates, factors for fatality of Acinetobacter infections and relationship between combination therapies and survival.Patients and Methods: We evaluated patients with Acinetobacter infection in ICU for demographic and clinical characteristics, combination therapies and adverse effects of these therapeutic options, retrospectively.Results: Ninety-one patients with proved Acinetobacter infection were included in this study. We found that the fatality rate of Acinetobacter infection in ICU was 56%. Advanced age, carbapenem resistance and Acinetobacter isolation from respiratory secretions were significantly related with fatality. We found that carbapenem resistance increased steadily during a 5 year period, fatality rates significantly decreased with combination therapies including aminoglycosides. There wasn’t significant relation between colistin therapy and survival in patients with Acinetobacter infections.Conclusion: The patients should be well-assessed in terms of fatality risk factors in case of Acinetobacter infections that occur in the intensive care units. The empirical antibiotic treatment started earlier based on such risk factors may decrease fatality. The antimicrobial combinations including aminoglycoside may be considered more in order to the local resistance data.
