An audit of central venous catheter insertion and management practices in an Australian tertiary intensive care unit: A quality improvement project

Abstract

Introduction: Central venous catheters are often used in managing critically ill patients. Clinical practice guidelines and care bundles exist to prevent central line associated blood stream infections; however, detailed adherence to these guidelines and care bundles is unclear. Aim: This study was aimed to describe clinicians’ adherence to recommended practices in central venous catheter insertion and management. Method: A cross-sectional prospective observational study was conducted in the intensive care unit of an Australian tertiary hospital over a four-month period. We observed a total of 50 nurses during post insertion management, and 10 physicians during central venous catheter insertion using purposely designed observation tools. Results: Our audit identified 90% adherence to recommended practices in central venous catheter insertion and 60% to post insertion management. However, there were areas where participants’ practices were not congruent with evidence-based recommendations, including choice of central venous catheter insertion site, type of central venous catheters, dressing choice, aseptic technique, and documentation. Conclusion: Our audit showed a detailed picture of clinician's adherence to recommended practices in central venous catheter insertion and management. A clearer understanding of the barriers and facilitators of issues identified is needed to inform the design of future interventions to reduce central line related blood stream infections in the unit.
