  1. Developing and investigating the use of a digital training package on chest radiograph image interpretation Ms Laura McLaughlin1, Dr Sonyia McFadden1, Dr Raymond Bond2, Dr Ciara Hughes1, Dr Jonathan McConnell31Centre for Health and Rehabilitation Technologies, Institute of Nursing and Health, School of Health Sciences, Ulster University (NI) 2Computer Science Research Institute, School of Computing and Mathematics, Ulster University (NI)3Queen Elizabeth University Hospital, NHS Greater Glasgow and Clyde, (Scotland)

  2. Contents Background Aim of the research Training platform • Structure • Formation • Layout • Digitisation Research Results Conclusion

  3. Background Limited role of radiographers within Northern Ireland 25.96% plain films in SHSCT Errors in image interpretation 30% discrepancy rate Delays in patient diagnosis Funding and research currently underway to address this

  4. Aim of the research To develop a digital platform aimed at improving chest radiographic image interpretation The training platform includes eye tracking technology and a search strategy for use in chest image interpretation

  5. Structure of the training platform The digital training platform consists of 2 sections: a digital search strategy training tool to assist reporting clinicians during their interpretation of images and also B) an educational multimedia tool to communicate the search strategies to trainees using eye tracking technology.

  6. Search strategy training toolFormation of the search strategy training tool: Two chest image interpretation search strategies used within clinical practicecombined Addition of further content and scrutiny until a comprehensive search strategy was developed Following many conversations by the research team the search strategy content was finalised

  7. Layout of the search strategy training tool Comprises a series of questions, images and prompts Includes 6 sections which focus on different anatomy, pathologies and artefacts Sections include: tube/lines/devices the bony thorax soft tissues diaphragm/heart/mediastinum lung zones lung shadows

  8. Educational programme Consists of videos of expert eye gazes and scan paths recorded during chest image interpretation and collected whilst the expert used the search strategy training tool. The expert’s eye gaze behaviours were recorded using the eye tracking technologyto provide a clear description of their search strategy.

  9. Educational programme Viewing environment was standardised Eye tracking quality was as high as achievable Experts provided additional information and explanation through their verbalisation

  10. Digitisation of the training platform Platform can be easily accessed on any device with an internet connection. A login feature monitors the use of the eye gaze enhanced videos and the search strategy training tool. This feature will supply a clear insight on the specific use of the training platform.

  11. Research Research is underway to investigate the impact of this digital platform  The platform was supplied to; reporting radiographers of the musculoskeletal system reporting radiographers of the chest cavity trainee radiologists Participants are being tested pre and post implementation of the training platform to investigate its effect on participant performance A survey will also be completed for feedback

  12. Results The intervention group achieved more true positives (p=0.033) and fewer false positives (p=0.024) following the intervention. The control group demonstrated no statistically significant changes following the nine month test period.

  13. Conclusions A novel digital training platform has been developed for use in training and to enhance the search strategies for the interpretation of chest images. Use of the digital platform significantly improved image interpretation performance for participants within the intervention group.

  14. Updates and looking ahead Completion of data collection in NI Data analysis Synthesis of results Use of the training platform
