Needleless connector science reviewed by Marcia Ryder


Exclusive presentation at #WoCoVA16 by Marcia Ryder, PhD, MS, RN on the topic of needleless connectors and the science behind bacterial transfer” ICU Medical (2016).


ICU Medical announce “CRBSI and catheter occlusion associated with needleless connectors remains a significant concern even after 20+ years of their existence. In this session, results of research comparing bacterial transfer rate and biofilm formation in 16 needleless connectors is presented. This study demonstrates that there are significant differences in the potential for biofilm formation and bacterial transfer among the connectors and catheters. But what accounts for these differences? Is it the design of the connector internal components? Is it the surface area of the flow-path? Is it flow-path residual volume? Is it the flow velocity within the connector flow path? The answers to these questions will be explored in this session. The results of these studies may become increasingly important for PIV catheters that remain in place greater than 96 hours under the clinically indicated site change standard. It is time to rethink our strategies for CRBSI prevention.”

Learning Objectives:

  • Describe the pathophysiology and impact of intraluminal biofilm as the major source of CRBSI.
  • Identify the critical design features associated with infection risks of needleless connectors and peripheral IV blood control catheters.
  • Understand the concepts of surface area, volume, and flow velocity in relation to biofilm formation and bacterial transfer risk.
