Abstract
|
|
|
Background: This study was conducted to evaluate the clinical characteristics and outcomes of mechanically ventilated patients with carbapenem-resistant Acinetobacter baumannii (CRAB) isolates from tracheal secretions in a medical intensive care unit (ICU) of a university hospital.
Methods: We conducted a retrospective study from January 2009 to June 2012.
Results: Among the patients who had isolates cultured from tracheal secretions, 130 patients (34.8%) had CRAB isolates. Their mean age was 65 ± 14 yr and 74.6% were male. The ICU and hospital mortality was 51.5% and 60.0%, respectively. According to physician`s clinical decision, antibiotics were changed in order to cover CRAB in 75 (57.7%) patients. The total duration of antibiotics use was 12.2 ± 8.1 days. Of patients with antibiotics change to cover CRAB, 70 patients (93.3%) had Clinical Pulmonary Infection Score of 6 and over. However, there was no significant difference in hospital mortality between patients with antibiotics change against CRAB and those without change. In multivariable analysis, only Acute Physiology and Chronic Health Evaluation II score was related to hospital mortality of patients with CRAB.
Conclusions: In this study, changing antibiotics to cover CRAB by physician`s clinical decision only did not influence hospital mortality; further studies would be necessary to investigate how to use antibiotics against CRAB isolates cultured from tracheal secretions.
