Results of in vitro research comparing twenty needleless connectors presented in this session demonstrate that there are significant differences in the bacterial transfer rate and intraluminal biofilm formation among needleless connectors. This session will examine the science behind bacterial transfer and biofilm colonization from connector septum to catheter tip, flow patterns, and the critical components of prevention by disinfection and frequency of change.

Learning Objectives:

  • What does biofilm have to do with needleless connector-related bloodstream infection?
  • Understand the impact of bacterial transfer, device design, flow patterns, and flow dynamics on intraluminal biofilm formation in a needleless connector/catheter system
  • Examine the critical factors for effective access site disinfection
