Medical imaging graduates' knowledge about infection prevention and control in pharmaceutical administration including contrast in CT and radiopharmaceutical in nuclear medicine

Introduction: Radiographic and nuclear medicine (NM) examinations utilizing pharmaceutical administration including contrast media (CM) and radiopharmaceuticals, have become essential for diagnosing a variety of diseases but may increase infection risks if infection prevention and control (IPC) are inadequately followed. This study investigates IPC knowledge and education among radiographers and NM technologists regarding pharmaceutical administration in medical imaging settings. Methods: A cross-sectional online questionnaire was administered to newly graduated radiographers and NM technologists in Australia. The survey assessed demographics, IPC knowledge, and perceived effectiveness of IPC training resources in the context of pharmaceutical administration including CM and radiopharmaceuticals. Data were analysed using descriptive statistics, chi-square tests, ANOVA, and content analysis. Results: Forty-five participants, mostly with bachelor's degrees and 4–5 years of experience, demonstrated high knowledge scores, with 87% scoring 9 or above. Theoretical training was rated as the most helpful IPC resource in university education. Challenges included limited practical opportunities at university, inconsistent supervision, and environmental factors affecting IPC compliance. Many participants reported gaps between university training and workplace practice, citing a need for more practical experience and targeted IPC education. Conclusions: The findings highlight critical gaps in IPC training for medical imaging professionals, particularly concerning the handling of CM in CT imaging. Strengthening IPC education through targeted, hands-on training and regular refresher courses is essential to improve compliance and safeguard both healthcare workers and patients. Addressing these educational gaps is vital for ensuring that medical imaging professionals are adequately prepared to reduce infection transmission risks in clinical settings.
