Usability of novel major TraumaApp for digital data collection

Background: Delivery of major trauma care is complex and often fast paced. Clear and comprehensive documentation is paramount to support efective communication during complex clinical care episodes, and to allow collection
of data for audit, research and continuous improvement. Clinical events are typically recorded on paper-based records
that are developed for individual centres or systems. As one of the priorities laid out by the Scottish Trauma Network
project was to develop an electronic data collection system, the TraumaApp was created as a data collection tool for
major trauma that could be adopted worldwide.
Methods: The study was performed as a service evaluation based at the Queen Elizabeth University Hospital Emergency Department. Fifty staf members were recruited in pairs and listened to fve paired major trauma standby and
handover recordings. Participants were randomised to input data to the TraumaApp and one into the existing paper
proforma. The time taken to input data add into was measured, along with time for clarifcations and any errors made.
Those using the app completed a System Usability Score.
Results: No statistically signifcant diference was demonstrated between times taken for data entry for the digital
and paper documentation, apart from the Case 5 Handover (p<0.05). Case 1 showed a signifcantly higher time for
clarifcations and number of errors with digital data collection (p=0.01 and p=1.79E-05 respectively). There were no
other diferences between data for the app and the proforma. The mean System Usability score for this cohort was 75
out of 100, with a standard deviation of 17 (rounded to nearest integer).
Conclusion: Digital real-time recording of clinical events using a tool such as the TraumaApp is comparable to
completion of paper proforma. The System Usability Score for the TraumaApp was above the internationally validated
standard of acceptable usability. There was no evidence of improvement in use over time or familiarity, most likely
due to the brevity of the assessments and the refned user interface. This would beneft from further research, exploring data completeness and a potential mixed methods approach to explore training requirements for use of the
TraumaApp
