Risk factors and prevalence of high resistant Acinetobacter spp among hospitalized patients

| May 2014 | 480 comparable with a report from USA that showed 46% of isolates were resistant to all of conventional antibiotics.[3] Totally, 66 isolates (95.65%) were carbapenem-resistant. In the six patients, Acinetobacter was isolated from multiple sites or one site for several times. It should be mentioned that all of six patients were infected or colonized with XDR strains, died during our study. Thus, this presumption exists that in some cases death was related to Acinetobacter infection or infection had accelerated patients’ death rate. Signifi cant risk factors for colonization/infection with XDR-strains were hospitalized duration (P = 0.048), underlying disease (P = 0.016), and corticosteroid usage (P = 0.030). In this study prevalence of Acinetobacter spp. was 7.98% while in Korea was 6.6%.[4] Many investigations reported prevalence of Acinetobacter particularly in the intensive care unit (ICU) ward. Prevalence of Acinetobacter spp. in the ICU ward of a hospital in Tehran was 22.4% and was most frequently isolated organism,[5] while in our study was 71.0%. This discrepancy may be due to several factors such as the condition of patients, management of infection control programs, type of strains and antibiotic resistance pa ern of isolates that it is eff ective in increasing of survival rate of them in the environment and colonization on the body of patients.
