Studies published between 1999 and 2011 demonstrated increased blood culture contamination with catheter-drawn cultures compared with percutaneously-drawn cultures. Studies published between 2012 and 2015 reported that use of antiseptic barrier caps on central venous catheter hubs significantly reduces the incidence of catheter-drawn blood culture contamination. Local guidelines regarding sites for blood culture collection should reflect institution-level blood culture contamination rates for percutaneously-drawn and catheter-drawn cultures using currently available technologies that reduce contamination at both sites.
