Purpose: In this study we aimed to investigate the incidence and effect of Acinetobacter baumannii infection on mortality in elderly patients admitted to intensive care unit. Materials and methods:We retrospectively investigated the medical records of elderly patients (>65 years) treated for more than 48 hours in our intensive care unit between 2013-2014. Defined risk factors in patients with or without A. baumannii infection were compared. Results: Medical records of one hundred and four patients mean age of patients was 77.1±6.9 were investigated. Most common nosocomial infection was ventilatory associated pneumonia in patients with A. baumannii infection (62.5%). Urinary catheter insertion was the most common invasive intervention (99%). Invasive interventions for instance; central venous catheterization, urinary catheter, mechanical ventilation and nasogastric tube insertion are defined as risk factors for A. baumannii infection, only mechanical ventilation is defined as independent risk factor (p=0.001). Mortality rates were significantly higher in patients infected with A. baumannii than non-infected patients (p=0.026). Conclusion: We showed that nosocomial A. baumannii infection leads higher mortality rates (p<0.05). Elderly patients prone to infections so this group of patients need to be evaluated as special patient population. All precautions have to be taken in order to avoid nosocomial infections and decrease mortality rates.
