opportunity for improvement
Each contaminated blood culture results in:

4.5 additional hospital days

Increased use of antibiotics and patient charges of $4400

Reduction of Contaminated Blood Culture Rate to 2.5% will result in a reduction of patient charges of $853,803 annually.

Opportunity for Improvement
project aim statement
Project Aim Statement
  • To evaluate the use of a disposable blood culture adapter to reduce the number of needle stick injuries and contaminated blood cultures.
  • According to CAP (College of American Pathologists), benchmark is 2% contamination rate. Evidence is Shifman et al. (1998). Blood Culture Contamination: a College of American Pathologists Q-Probe Study. Archives of Pathology and Laboratory Medicine: 122, 216-221.
summary 3news pilot study
Retrospective Study January-October 2006: Blood Culture Contamination Rate was 6%.

Two Month Trial Results:

May 2007 :

Blood Culture Contamination Rate 4%

June 2007:

Blood Culture Contamination Rate 1%

Summary 3NEWS Pilot Study
pilot study 3 news
Pilot Study 3 NEWS
  • Goal was to reduce peripheral blood culture contamination rate to 2.5%
  • 3 NEWS pilot lasted 2 months with a reduction in blood culture rate from contamination from 6% to 1%
  • Decision to role out project house wide Jan 2009
slide6

With the introduction of the adapter, the rate of contamination decreased on average of 2.6 for the past three months. January 2009 experienced a decrease to 2.3, surpassing our goal of 2.5.

analysis
Analysis
  • Implementation of the blood culture adapter house wide has resulted in a blood culture contamination rate of 2.7% in January and February
  • The implementation of the adapter has decreased contamination rate
next steps
Next Steps
  • Monitor the monthly blood culture to insure that the target contamination rate of 2.5% is met
  • Evaluate additional blood culture adapter which could be used in blood culture line draws to reduce contamination rate below 2%
