The Introduction of an Undergraduate Interventional Radiology (IR) Curriculum: Impact on Medical Student Knowledge and Interest in IR

Abstract

Introduction: Interventional radiology (IR) plays a vital role in modern medicine, with increasing demand for services, but with a shortage of experienced interventionalists. The aim of this study was to determine the impact of a recently introduced IR curriculum on perception, knowledge, and interest of medical students regarding various aspects of IR.

Methods: In 2014, an anonymous web-based questionnaire was sent to 309 4th year medical students in a single institution within an EU country, both before and after delivery of a 10-h IR teaching curriculum.

Results: Seventy-six percent (236/309) of the respondents participated in the pre-IR module survey, while 50% (157/309) responded to the post-IR module survey. While 62% (147/236) of the respondents reported poor or no knowledge of IR compared to other medical disciplines in the pre-IR module survey, this decreased to 17% (27/157) in the post-IR module survey. The correct responses regarding knowledge of selected IR procedures improved from 70 to 94% for venous access, 78 to 99% for uterine fibroid embolization, 75 to 97% for GI bleeding embolization, 60 to 92% for trauma embolization, 71 to 92% for tumor ablation, and 81 to 94% for angioplasty and stenting in peripheral arterial disease. With regard to knowledge of IR clinical roles, responses improved from 42 to 59% for outpatient clinic review of patients and having inpatient beds, 63-76% for direct patient consultation, and 43-60% for having regular ward rounds. The number of students who would consider a career in IR increased from 60 to 73%.

Conclusion: Delivering an undergraduate IR curriculum increased the knowledge and understanding of various aspects of IR and also the general enthusiasm for pursuing this specialty as a future career choice.
