Pre-registration UK diagnostic radiography student ability and confidence in interpretation of chest X-rays

Introduction Chest X-rays are the most frequently requested X-ray imaging in English hospitals. This study aimed to assess final year UK radiography student’s confidence and ability in image interpretation of chest X-rays. Methods Thirty-three diagnostic radiography students were invited to assess their confidence and ability in interpreting chest x-rays from a bank of n=10 cases using multiple choice answers. Data analysis included 2x2 contingency tables, Kappa for inter-rater reliability, a Likert scale of confidence for each case, and questions to assess individual interpretation skills and ways to increase the learning of the subject. Results Twenty-three students participated in the study. The pooled accuracy achieved was 61% (95% CI 38.4-77.7; k=0.22). The degree of confidence and ability varied depending upon the student and the conditions observed. High confidence was noted with COVID-19 (n=12/23; 52%), lung metastasis (n=14/23; 61%), and pneumothorax (n=13/23; 57%). Low confidence was noted with conditions of consolidation (n=8/23; 35%), haemothorax (n=8/23; 35%), and surgical emphysema (n=8/23; 35%). From the sample n=11 (48%), participants stated they felt they had the knowledge to interpret chest X-rays required for a newly qualified radiographer. Conclusion The results demonstrated final year radiography student’s confidence and ability in image interpretation of chest X-rays. Student feedback indicated a preference for learning support through university lectures, online study resources, and time spent with reporting radiographers on clinical practice to improve ability and confidence in interpreting chest X-rays.

Interactive teaching environment for diagnostic radiography with real-time X-ray simulation and patient positioning

Purpose Traditional undergraduate radiographer training mixes academic lectures and clinical practice. Our goal is to bridge the current disconnection between theory and practice in a safe environment, avoiding the risk of radiation for both practitioners and patients. To this end, this research proposes a new software to teach diagnostic radiography using real-time interactive X-ray simulation and patient positioning. Methods The proposed medical simulator is composed of three main modules. A fast and accurate character animation technique is in charge of simulating the patient positioning phase and adapts their internal anatomy accordingly. gVirtualXRay is an open-source X-ray simulation library and generates the corresponding radiographs in real time. Finally, the courseware allows going through all the diagnostic radiology steps from the patient positioning and the machine configuration to the final image enhancing. Results A face and content validation study has been conducted; 18 radiology professionals were recruited to evaluate our software using a questionnaire. The results show that our tool is realistic in many ways (72% of the participants agreed that the simulations are visually realistic), useful (67%) and suitable (78%) for teaching X-ray radiography. Conclusions The proposed tool allows simulating the most relevant steps of the projectional radiography procedure. The virtual patient posing system and X-ray simulation module execute at interactive rates. These features enable the lectures to show their students the results of good and bad practices in a classroom environment, avoiding radiation risk.

Task-specific short PowerPoints for effective off-campus learning in Diagnostic Radiography

This case study details the implementation of task-specific PowerPoint™ presentations for an undergraduate diagnostic radiography module in response to the first COVID-19 lockdown in the United Kingdom. A series of short, focussed learning materials was created over a two-month period to alleviate student anxieties and improve assessment literacy concerning evidence-based practice and research skills. Alternative file sizes were offered with optional embedded narration for time- or internet-poor students. Statistical tracking on the Blackboard virtual learning environment showed high levels of student interaction, with positive qualitative feedback and satisfactory impact upon assessment outcomes. A correlation between a lack of content usage and poor academic results could be inferred, with three students failing one or both assessments through reduced or absent use. Despite the benefits of weekly additional content, it was not possible to ascertain whether students viewed/listened to downloaded files. Furthermore, instructional presentations may encourage surface learning rather than a deeper comprehension. Recommendations include using video streaming platforms to provide meta-data on student interaction alongside periodic formative assessments for confirmation of comprehension. Lastly, this research recognises remote learning’s potential to alienate students who prefer in-person teaching in a more sociable environment.
