Radiographers' perceptions of intravenous cannulation and administration of contrast media: A qualitative study in a...

Intravenous cannulation and contrast media (IVCM) administration are diagnostic procedures that enhance the quality of medical imaging examinations. In Zambia, radiologists and nurses traditionally perform IVCM administration due to radiographers' limited scope and lack of specialised training. However, radiographers have begun assisting or performing IVCM administration amid personnel shortages despite limited scope of practice. This study explores Zambian radiographers' perceptions of expanding their roles to include IVCM administration within diagnostic imaging.

After ethical approval, a descriptive, phenomenological approach was used to conduct this study. Eight radiographers from two government hospitals in the Lusaka Province were interviewed. Interviews were recorded, transcribed, and analysed thematically using Braun and Clarke's framework to explore the participants' experiences, competencies, and challenges related to IVCM administration.

Four themes were developed: (1)Challenges and concerns related to IVCM administration, (2) Scope of practice for radiographers in Zambia, (3) Role extension and professional development in IVCM administration, and (4) Radiographer training and competence in IVCM administration. Radiographers expressed strong interest in expanding their scope to include IVCM but noted barriers such as inadequate training, limited resources, and safety concerns. They emphasised the need for institutional support and structured training to build competence and confidence.

The findings highlight opportunities to strengthen radiography education, training, and reform policy in Zambia, potentially improving diagnostic imaging and patient outcomes. The insights may benefit other African countries with similar healthcare settings.

Radiographers' willingness to extend their roles calls for formal recognition and support for their involvement in IVCM administration. Addressing current barriers could empower radiographers, improve service delivery, and enhance patient safety aligned with international standards.
