Background

Precise interpretation and presentation of abdominal (AXR) and chest radiographs (CXR) are essential skills required to ensure optimal management and outcomes for patients. They are skills that a junior doctor is expected to have basic competency in and which are essential for on call situations, referrals and for professional examinations. Whilst radiograph interpretation is often taught by lectures, presentation and focused teaching on these skills is often only taught anecdotally on the wards. Through facilitated small group workshops, delivered at an early stage of medical students’ training, we aimed to provide a framework for AXR and CXR interpretation and presentation. We designed this study to estimate the efficacy of these total participation workshops in improving radiograph interpretation skills and presentation confidence.

Summary of Work

 

We included 77 third year medical student volunteers who attended a rotation at a tertiary London teaching hospital from January to April 2013. All students underwent a total participation workshop on CXR (n=39) or AXR (n=38), which included teaching a framework for interpretation and presentation followed by practicing these skills in a small group of 4-6 with a facilitator giving active feedback. Radiograph interpretation skills were tested using multiple choice questions (MCQs) before and after the workshop. Students also scored their confidence and effectiveness of their presentation and their overall personal confidence on a scale of 0-10. Those scoring their personal confidence from 0-5 were grouped as low or non-confident and those scoring from 6-10 as confident.

Summary of Results

Following the workshop, students reported an increase in presentation confidence from 4.4 to 7.0 (p<0.05) and presentation effectiveness from 4.2 to 6.8 (p<0.05). 37 students had low confidence (CXR = 20, AXR =17) whilst 40 had high confidence (CXR =19, AXR = 21). Students who ranked their baseline confidence as low reported a 9% greater increase in presentation confidence and effectiveness compared to their high confidence counterparts.

Following each workshop there was an increase in MCQ performance with the number of students correctly answering MCQs rising from 50.25% to 87.25% (p<0.05). There was not a statistically significant difference in the pre or post workshop performance between groups.

Students strongly agreed that these workshops should be integrated into their curriculum (Average 8.9 / 10).

Conclusion

Focused facilitated workshop teaching on radiograph interpretation and presentation early in training can improve both subjective and objective outcomes. This method of teaching may benefit students with low personal confidence in particular.

Take-home Messages

Focused facilitated workshops are an effective method for teaching radiograph interpretation and presentation. The positive outcomes on student confidence, diagnostic ability and support for this learning style support integration where possible into the medical school curriculum.
