Effectiveness of introducing blood culture collection packs to reduce contamination rates

Abstract Contaminated blood cultures result in a significant waste of healthcare resources and can lead to inappropriate antibiotic therapy. Practitioners have taken measures to reduce contamination rates. These include thorough skin disinfection, effective hand decontamination, introduction of a standardised approach to collection, and the introduction of blood culture collection packs (BCCP). This study aims to assess the impact of introducing BCCP and staff training on the rate of contamination. The study demonstrated that contamination rates are greatest in high patient throughput units where practitioners are under most pressure. The introduction of blood culture packs and staff training has reduced contamination rate significantly from 43% to 25% of the total number of positives, equating to an overall reduction of 42%. Thus, there is a demonstrable benefit in the purchase of commercially produced blood culture packs and the investment in staff training.
