Carbapenem-resistant Acinetobacter baumannii complex bacteraemia in elderly patients in northern Taiwan

The elderly patients (aged ≥ 65y) among general population have increased in Taiwan. The aim of this study is to identify the risk factors for attributable mortality among elderly patients with carbapenemresistant Acinetobacter baumannii (CRAB) complex bacteraemia. A retrospective study of patients with CRAB complex bacteraemia at a medical center in northern Taiwan from 2009 to 2013 was performed. Variables such as clinical characteristics, antibiotics susceptibilities, and outcomes were compared between elderly patients (aged ≥ 65y) and the other patients (aged 25 (OR 6.702, p = 0.001), respiratory tract source (OR 4.416, p = 0.026) and cefepime (OR 13.203, p = 0.023). Our findings show at the hospital in northern Taiwan, elderly patients (aged ≥ 65y) with CRAB complex bacteraemia had a different epidemiology than the other patients (aged 25, respiratory tract source and the use of cefepime had associated with mortality. Infection control measures, especially for respiratory tract source and early adequate treatment may be helpful in the survival of elderly patients (aged ≥ 65y).
