An analysis of interventional radiology training needs of radiology registrars in South Africa.

Background: Interventional radiology (IR) is rapidly growing as a critical subspeciality, yet in South Africa (SA) IR training remains underdeveloped, with no national data to guide structured training and workforce expansion. Objectives: This study aimed to assess South African radiology registrars' interest in IR, their exposure, and the existing training environment. Method: A cross-sectional, electronic quantitative and qualitative survey was conducted from 09 February 2024 to 08 March 2024 among registrars affiliated with the Radiological Society of South Africa. The survey gauged their interest in IR, exposure, training infrastructure, learning tools, satisfaction with training and potential areas for improvement. Results: Response rate: 45% (100/221 registrars); 54% were female, median age was 33.4 years and 51% in their first or second year. Interest in IR as a subspeciality was expressed by 40%, 27% were not interested and 33% were unsure. Only 27% reported adequate exposure; 56% had limited exposure and 17% had none. Dissatisfaction with IR training was noticed by 47%, 37% were undecided and 16% were satisfied. Only 9% had a structured curriculum, while 23% relied on mentorship. Major themes for improvement included structured training, mentorship, supervision, training facilities and hands-on exposure. Conclusion: Despite strong interest, radiology registrars (including international supernumerary registrars) face significant gaps in IR training and exposure in SA. Contribution: This is the first national study to provide essential baseline data to inform targeted reforms and development of structured, locally relevant IR training.
