Abstract

Blood cultures' contamination (BCC) is associated with unnecessary processing of cultures, higher cost, and occasionally, unjustified antibiotic treatment. We aimed to reduce the rate of BCC by educational intervention. In parallel, we also strove to expand the use of aminoglycosides (AMG) and reduce the utilization of beta-lactam antibiotics. The rate of BCC was assessed prospectively in the study department - the Emergency Department (ED) and in control departments - Medical Departments A, B and Geriatrics. Data was collected continuously during the study period and educational interventions were performed in the ED but not in the control departments. The intervention included meetings with ED staff, emphasizing proper blood culture collection technique, and post-intervention result updates. The utilization of AMG was encouraged in cases of suspected gram-negative bacteremia. The empirical and definitive antibiotic regimen was assessed. During the study period, a 30% decrease in BCC rate [33/564 (5.9%) to 30/734 (4.1%), p=0.143] was noted in the study department whereas a small increase in BCC rate was noted in the control departments. Logistic regression analysis revealed significantly different trends in BCC rate between th...Continue Reading
