  • Skin, however, cannot be sterilized during antisepsis procedures because approximately 20% of bacteria are imbedded within deep layers of the epidermis and dermis.
  • Blood cultures should be obtained prior to starting antibiotic therapy to optimize the recovery of pathogens.
  • Estimated up to 50% of all blood cultures originate in the ED. Crowding in EDs is correlated with higher rates.
  • Improper collection of blood cultures is associated with suboptimal treatment of patients, increased financial burdens, and potential over-reporting of CLABSI.
  • Costs of a false positive blood culture range from $4500-$10,000.
