Abstract

 We have started a campaign to promote appropriate implementation of blood culture in our hospital. This campaign includes lectures for medical staff and students, evaluation of patients with positive blood culture, reporting the implementation status of blood culture at infection control meetings, implementation of blood sampling by nurses, and simplification and manual revision of blood sampling. We investigated 38,813 blood culture samples obtained between January 2009 and December 2014. The number of blood culture sets, the rates of multiple sets, contamination rates and positive rates were evaluated. The number of blood culture sets increased from 3,168 sets in 2009 to 4,920 sets in 2014. Blood culture sets per 1,000 patient-days also increased from 12.4 sets in 2009 to 19.3 sets in 2014. The rate of multiple set increased from 30.6% in 2009 to 73.3% in 2014 in adult inpatients, and 43.0% to 85.7% in adult outpatients. Contamination rate was 3.5% in 2009 and decreased to 2.7–2.9% after 2010. Positive rates decreased from 15.1% in 2009 to 11.0% in 2014 in adult inpatients, from 22.2% to 18.7% in adult outpatients and from 9.4% to 2.6% in pediatrics. Positive rates of multiple sets were consistently higher than those of single sets. Our campaign promoted the appropriate implementation of blood culture and improved several parameters. Combination and continuation of multiple activities was effective for staff education and promotion of appropriate blood culture sampling.<br>
