Factors Influencing the Choice of Radiology Subspecialty Among Radiology Trainees in Sudan

Background and objective There are numerous reasons why radiologists would be interested in seeking additional fellowship training, some of which are personal, such as the possibility of bettering their career prospects, while others are work-related. This study aimed to identify whether the Sudanese radiology trainees wanted to pursue fellowship and what were the motivating and restricting factors affecting their career choices. Methods This was a re-do research of a study from Saudi Arabia previously published in the Cureus journal in 2019. This was a descriptive cross-sectional study conducted among the radiology registrars training under Sudan Medical Specialization Board (SMSB) in 2022 (n=90). By using convenient sampling, 74 of the 90 registrars were contacted, and a response rate of 81% (n=60) was achieved. Data were collected using a pre-tested self-administered online questionnaire. Data were analyzed using IBM SPSS® Statistics version 25.0 (IBM Corp., Armonk, NY). A p-value ≤0.05 was considered statistically significant. Results The majority of the trainees in our study were females (61.7%, 37/60). More than 93% (n=56) of our participants were training in Khartoum, the capital of Sudan. The most commonly chosen subspecialties in our study were as follows: neuroradiology (33.3%, n=20) body imaging (26.7%, n=16), and interventional radiology (25%, n=15). In contrast, nuclear medicine (1.7%, n=1) and emergency radiology (3.3%, n=2) were among the least popular subspecialties. The top influencing factors among our trainees in choosing a subspecialty included "strong personal interest," "lifestyle," and "area of strong personal knowledge." The most common factors preventing trainees from opting for a fellowship were "financial restriction" (55%, n=33) and "family obligation" (28.3%, n=17). Of those with no plans to subspecialize, 75% (six out of eight) stated that the lack of a fellowship program in Sudan is a possible deterrent. A statistically significant association was found between gender and the choice of subspecialty in interventional radiology and women’s/mammogram imaging. Our findings revealed that there are currently no trainees in the first year of radiology residency because the last selection exam had been conducted in 2019. Despite the current unavailability of subspecialty training in Sudan, 75% (n=45) of trainees in our study were interested in joining a local program for fellowship training in the future. Conclusion Radiology trainees in Sudan share similar interests and influencing and restricting factors when pursuing subspecialty training, as reported in the literature. Unlike other countries, females predominate in the field of radiology training in Sudan at the moment. Radiologists from Sudan who are interested in subspecializing usually travel abroad for training; and once they find better prospects, many of them may not return. Programs offering subspecialization locally could mitigate the attrition of radiologists in Sudan. When designing subspecialty training programs in Sudan, stakeholders should use knowledge of influential factors and understanding of subspecialty decision trends among radiology trainees as a reference point. To the best of our knowledge, this study is the first of its kind to be conducted in this field in Sudan.
