Risk factors of mortality in patients with carbapenem-resistant Acinetobacter baumannii bacteremia

Background/Purpose Identification of risks of mortality for carbapenem-resistant Acinetobacter baumannii (CRAB) , with early implementation of an appropriate therapy, is crucial for the patients' outcome. The aim of this study was to survey mortality risk factors in 182 patients with CRAB bacte...

Description
Summary:Background/Purpose Identification of risks of mortality for carbapenem-resistant Acinetobacter baumannii (CRAB) , with early implementation of an appropriate therapy, is crucial for the patients' outcome. The aim of this study was to survey mortality risk factors in 182 patients with CRAB bacteremia in a medical center in Taiwan. Methods A total of 182 isolates of CRAB bacteremia were collected from 2009 to 2012 in Mackay Memorial Hospital, Taipei, Taiwan These isolates were identified by using the genotypic method. Risk of attributable mortality analysis was carried out with a Cox proportional hazards model. Results The 182 CRAB isolates belonged to 38 different pulsotypes. The attributable mortality rate of the 182 patients was 58.24%. The risk factors for attributable mortality included intensive care unit stay [hazard ratio (HR): 2.27; p  = 0.011], an Acute Physiology and Chronic Health Evaluation II score of >20 (HR: 2.19; p
