IntroductionRoutine monthly monitoring of blood culture (BC) contamination rates detected a spike (>3%) in false-positive BCs drawn in the emergency department. This triggered an ad hoc quality-improvement team to develop and implement a corrective action plan in our 230-bed urban community hospital with 58,000 ED visits annually.MethodsBoth phlebotomists and nurses draw BCs in the emergency department; therefore all interventions were directed at both groups. These included private conversations with individual staff members associated with higher numbers of contaminated draws compared with peers, ensuring availability of necessary BC collection supplies, re-education of all phlebotomists and ED nursing staff surrounding BC collection best practices, monthly feedback to staff on BC contamination rates, and continuing private conversations as necessary, regardless of the contamination rate.ResultsBefore the spike in the emergency department, the average rate of BC contamination for the hospital as a whole was 1.82% (January-July 2011). Excluding 3 months when ED contamination was greater than 3% and the hospital contamination rate was 2.65% (August-October 2011), the average rate of BC contamination for the hospital dropped to 1.01% after the interventions (November 2011-June 2012). This represents a 44% decrease moving from 1.82% to 1.01% in hospital-wide BC contamination rates and an annualized cost avoidance of approximately $614,000.DiscussionThe ED BC contamination rate spike occurred over a 3-month period during which the emergency department was transitioning into a new facility on the same campus. The total hospital BC contamination rate never rose above the 3% benchmark, which illustrates the importance of tracking ED-specific data.Copyright © 2013 Emergency Nurses Association.
