Introduction: Seizing Control of Blood Culture Contamination Rates (02:06)


Contamination rates are one of the biggest problems laboratories face. Topics will include: blood culture necessity, bacteremia sources, the purpose of multiple sets, contamination costs, realistic goals, and strategies to reduce contamination rates.

Why Order Blood Cultures? (02:04)

Cultures rule in or rule out systematic infections. Sources of septicemia include: colonized intravascular devices and extravascular sources.

Why Multiple Sets? (03:37)

A single set of cultures has little predictive value; see a list of common blood culture contaminants and contamination indicators. Multiple sets may be timed, un-timed, or per fever.

Cost of Contamination (02:57)

Studies indicate that the cost per contaminated culture for inpatients range from $2,889- $8,720; patient stay can increase up to 3.3 days. Outpatient costs result in $152 per false positive culture; 26% of pediatric patients are hospitalized unnecessarily.

Cost Avoidance (03:53)

See a comparison of hospital costs per contaminated culture for emergency department patients and the cost avoidance of a third hospital when keeping contamination rates below 2%. Studies suggest that on average 10% of all blood cultures will be positive; 40% of those represent contaminants. See graphs of savings when reducing rates by one percent.

Your Contamination Rate: What Should We Target? (02:27)

The ASM states that the rate should not exceed 3%; experts recommend a target rate of 2%. See contamination rates in centralized vs. decentralized environments.

Seizing Control (01:04)

Knowledge of proper blood collection technique and the implementation of management strategies reduce the contamination rate.

Seizing Control: Collection Technique (09:38)

Chlorhexidine is the most widely used antiseptic for venipunctures. Hear recommendations for site prep, re-palpating, sterile glove use, stopper cleansing, specimen diversion, SPS tubes, and VADs.

Seizing Control: Management Strategies (02:15)

A CDC evidence review panel found two best practices for blood culture contamination rate reduction: venipuncture instead of a line draw and employing a dedicated phlebotomy team.

Seizing Control: Train (01:29)

Use the "train, track, and treat" methodology to reduce blood culture contamination rates. Train the phlebotomist first and then non-lab blood collection personnel in the six elements of collection technique.

Seizing Control: Track (02:33)

Monitor blood culture contamination rates by individual and department, and communicate the rate. Establish benchmarks for top and bottom performers.

Seizing Control: Treat (00:56)

Positive reinforcement is just as important as feedback. Feed an individual or department when blood culture contamination rates are trending downward.

Seizing Control: Admin. Support (02:54)

Learn tips for winning administration support for the "train, track, and treat" methodology to reduce blood culture contamination rates.

Seizing Control: Sustaining the Gains (01:52)

Keeping down blood culture contamination rates is ongoing and always necessary. Tips include: "train, track, treat;" employ best practices; eradicate other methods; communicate the rate; and employ revocation if necessary.

Rate Summary (01:31)

3-Year Streaming Price: $299.95



Do you have too many contaminated blood cultures? Do you need strategies to reduce them in your facility? You're not alone. On average, treating patients for false-positive blood cultures cost hospitals $5000 in unnecessary antibiotic therapy and laboratory tests. They also extend the patient's hospital stay by 3.3 days. This program discusses the most common causes of blood culture contamination and strategies to reduce contamination rates in your facility, even where phlebotomy services have been decentralized.
