Prevention of extravasation of intravenous computerised tomography contrast media among adult patients in the Medical Imaging Department of an Acute Tertiary Hospital: A best practice implementation project

Abstract

Background Intravenous Computerised Tomography (CT) contrast media extravasation is an uncommon but preventable risk of CT scans. Good screening methods can mitigate this risk, although they cannot eliminate it. Objectives The aim of this project was to promote best practice administration of CT contrast media in the Medical Imaging Department of the Canberra Hospital and thereby make a contribution to reducing incidence of extravasation from IV CT Contrast Media and improving patient outcomes. Methods Audit based on best-practice evidence was used to determine screening and extravasation prevention practices in the CT Department of an acute tertiary hospital. This audit surveyed 50 inpatients attending the CT department for CT scan with intravenous contrast. An intervention of poster development, education and discussion of issues identified was instigated and a post-implementation audit was undertaken. Results There was improvement in some areas of clinical practice following an education and awareness program. The need for an assessment tool to assist in determining patients at risk of extravasation was highlighted. Rather than an assessment tool, a poster was developed, and compliance with best practice was improved. Areas for future interventions to close continuing gaps between practice and best practice were identified. Conclusions The findings show that an effective education program can make a contribution to improving awareness of the risk factors for IV CT contrast extravasation and measures for preventing this.
