Does a Vascular Access Specialist Model in the Emergency Department (VAS-ED) improve peripheral intravenous catheter outcomes? A Randomised Controlled Trial
Grant ID: EMLE-283R41-2024-XU
Project Summary
More than 6 million peripheral intravenous catheters (PIVCs) are inserted in patients' veins in Australian emergency departments (EDs) annually. These devices can be challenging to insert, and over half will fail before the treatment is finished. Although ED clinicians regularly insert PIVCs, most inserters are junior medical or nursing staff who often default to short PIVCs because that is what they were trained to insert. These “generalist” inserters often don’t have the skills or knowledge to select alternate vascular access devices appropriate to the patient's needs. In contrast, Vascular Access Specialists (VAS) are experts with advanced assessment and expertise in inserting and managing vascular access devices, a model that has proven successful in inpatient wards, but hasn’t yet been tested in the ED setting.
In this study, we will compare the effectiveness and cost of using VAS specialists versus generalist inserters for peripheral IV device selection and insertion. In total, 320 ED patients will be recruited and randomly allocated to receive either a VAS or generalist inserter (standard care). We will compare outcomes including first-time insertion success, device failure rates, complications, patient satisfaction, and cost between the two groups. Additionally, we will interview clinicians to better understand the barriers and facilitators to implementing and using a VAS model.
We expect that patients who have a peripheral IV device inserted by a VAS will have higher first-time insertion success, and be more satisfied with their care than patients allocated to the generalist group.
