Introduction:
RADUCATION - a digital platform for radiological postgraduate training by the German Young Radiology Forum - provides learning content structured according to the German Training Curriculum, including original board exam questions. This is the first study to evaluate user statistics, experience, and preferences.
Materials And Methods:
Data were collected through webpage analytics and surveys. User statistics were analyzed for four periods: initial usage (05/2022-05/2023), post-introduction of theoretical board exam questions (05-11/2023), post-introduction of image-based board exam questions (12/2023-05/2024), and ongoing usage (03-12/2024). User perception surveys were conducted before (05/2023-01/2024) and after (06-08/2024) implementation of image-based board exam questions. Analyses included descriptive statistics and multivariable logistic regressions.
Results:
User numbers increased steadily, with board exam questions becoming the most accessed feature. Mean monthly active user numbers increased from 372 between 05/2022-05/2023 (total users 4468), to 613 between 03/2024-12/2024 (total 15,828). Survey respondents (n = 243) consistently rated RADUCATION as valuable for board exam preparation (88.6%), for night/weekend shifts (75.6%), and for clinical routine (73.4%). Board exam preparation was more beneficial for 4th/5th-year residents (odds ratio (OR) 1.35 (95% confidence interval (95% CI): 1.15-1.59)), while shift preparation was less critical for senior than for junior residents (OR 0.77 (95% CI: 0.59-0.99)). Video- and image-based learning content were preferred, with users rating the platform highly user-friendly (86.0%) and clearly structured (88.0%).
Conclusions:
RADUCATION is a valuable, widely used digital learning tool for radiology residents. Board exam questions substantially increased engagement. Its structured, peer-developed design offers a scalable model for digital postgraduate medical education across specialties and countries.
Critical Relevance Statement:
This is the first comprehensive evaluation of RADUCATION, a peer-developed, competency-based digital learning platform for the radiology residency. Integrating original board exam questions significantly increases engagement and perceived educational value, offering a scalable model for modern postgraduate medical education.
Key Points:
RADUCATION, a peer-developed, competency-based learning platform for radiology residents, is a highly valued, scalable model for postgraduate medical training. Users prefer video- and image-based content, while engagement and perceived educational value increase when integrating original board exam questions. RADUCATION is perceived as user-friendly and well-structured, and is considered particularly valuable for exam preparation by senior residents.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
