Exploring the implementation of role extension for Namibian radiographers: Perspectives on intravenous injection of contrast media

Abstract

IntroductionRole extension to include intravenous (IV) injection of contrast media has been formally embraced by radiographers and their regulatory bodies in developed countries. The revised scope of practice, in our Namibian context, has formalised IV injection as an extended role for radiographers. This study aimed to explore the perspectives of radiographers regarding this new role of IV injection of contrast media. MethodsA qualitative design with a descriptive phenomenological approach was employed to collect data from 15 radiographers working in both public and private radiology facilities. Participants were purposively selected to participate in focus group discussions and individual interviews. An interview guide was used to facilitate the discussions and interviews, and a voice recorder was used for recording. Data were transcribed verbatim and analysed using Tesch's 8-step method. ResultsFrom the 15 participants, three themes were developed: enhanced service delivery with two subthemes (improved departmental workflow and patient care), training needs with two subthemes (inadequate contrast media reaction training and standardised training requirement), and medical-legal issues with two subthemes (regulatory blurriness and role conflict distress). ConclusionThe participants expressed mixed perceptions towards the IV injection role of radiographers, emphasising the benefits for the department and patients while raising concerns regarding standardisation of training and associated medico-legal issues. Furthermore, a large-scale evaluation is necessary to uncover the challenges and barriers to the successful adoption of this new role. Implications for practiceThe role extension for radiographers to include IV injections is a long-awaited development, but it should be accompanied by the necessary training and guidelines to fully realise its benefits.
