Aim Statement Goal: To reduce blood culture contaminants to 3% or below *Potential Consequences of Contaminated Blood Cultures: p Exposure to antibiotics can lead to acquisition of multidrug resistant organisms p Additional diagnostic testing p Prolonged hospital stay or unnecessary admission p Increased costs and utilization of resources p Decreases the positive predictive value of the blood culture system *Clinical Laboratories Standards Institute/College of American Pathologists Confidential - Quality Improvement Materials
Multidisciplinary Team Plan p Form a multidisciplinary team to reduce blood culture contaminants p Review historical data related to blood culture results p Review literature for “best practices” in obtaining blood cultures p Create a blood culture competency to address staff knowledge deficit related to blood culture collection p Direct efforts to decrease contamination rate for ED specimens p Target staff collecting blood cultures: Phlebotomists and Emergency Department staff p Explore clinical lab blood culture systems Confidential - Quality Improvement Materials
Actions Implemented p Required ED nursing staff to complete Blood Culture competency at hire and quarterly p Required return demonstration of specimen collection including itemized steps on competency p Educated staff on basic knowledge regarding skin antisepsis, central line catheter biofilm, and consequences of contaminated blood culture results p Developed department trainers to educate staff p Implemented Versatrek blood culture collection system p Performed analysis of potential costs attributed to contaminated specimens Confidential - Quality Improvement Materials
Ongoing Actions p Monitor blood culture contaminant results monthly p Communicate contaminant results to department manager p Share department results with staff monthly p Provide direct feedback of individual performance p Re-educate staff as needed p Share results with key stakeholders Confidential - Quality Improvement Materials
Goal ≤ 3% Confidential - Quality Improvement Materials
Individual Counseling and competency of ED personnel Versatrek Blood Culture System Implemented house-wide Goal 3% Analysis: Since individual counseling and education of ED staff in Q 1 2007, the rate of blood culture contamination has decreased consistently. Further improvement noted after implementation of new blood culture system house-wide. The ED achieved rates below the benchmark goal of 3% in the last two quarters. Overall mean average is at 4. 62.
Goal 3% Versatrek Blood Culture System Implemented house-wide Analysis: The Phlebotomy department consistently performs below the benchmarking goal of 3%. Further improvement noted after implementation of new blood culture system house-wide. Overall mean average is maintained at 1. 76.
Cost of a Contaminated Blood Culture p Estimated Cost per Contaminant= $4500. 00** p Estimate Cost Avoidance Associated with the Reduction Contaminated Blood Culture Rate 5 fewer contaminants per quarter would yield potential cost savings of $90, 000 annually ** Reference: College of American Pathologists, 2000 Confidential - Quality Improvement Materials
Analysis p Emergency Department achieved 2. 7% contamination rate 3 rd quarter calendar year 2008 p Achieved 2. 6% overall contamination rate 4 th quarter calendar year 2008 p Preliminary 1 St quarter calendar year 2009 data: overall contamination rate 2. 8% p Sustained improvement achieved in 2008 with implementation of Versatrek blood culture collection system and quarterly blood culture competency training Confidential - Quality Improvement Materials
Next Steps p Intervene with education and analysis of any upward trending p Continue ED staff requirement to complete quarterly competency p Ongoing review of literature for best practices related to skin antisepsis, specimen collection, and care and maintenance of a central line p Maintain collaborative team and continue reporting to key stakeholders p Sustain blood culture contamination rate at or below 2% (revised national benchmark) Confidential - Quality Improvement Materials
