Abstract

Rationale, aims and objectives The goal of this study is to determine usability gaps between expert and novice primary care doctors when using an electronic health record (EHR). Methods Usability tests using video analyses with triangular method approach were conducted to analyse usability gaps between 10 novice and seven expert doctors. Doctors completed 19 tasks, using think-aloud strategy, based on an artificial but typical patient visit note. The usability session lasted approximately 20 minutes. The testing room consisted of the participant and the facilitator. Mixed methods approach including four sets of performance measures, system usability scale (SUS), and debriefing session with participants was used. Results While most expert doctors completed tasks more efficiently, and provided a higher SUS score than novice doctors (novice 68, expert 70 out of 100 being perfect score), the result of 'percent task success rate' were comparable (74% for expert group, 78% for novice group, P = 0.98) on all 19 tasks. Conclusion This study found a lack of expertise among doctors with more experience using the system demonstrating that although expert doctors have been using the system longer, their proficiency did not increase with EHR experience. These results may potentially improve the EHR training programme, which may increase doctors' performance when using an EHR. These results may also assist EHR vendors in improving the user interface, which may aid in reducing errors caused from poor usability of the system.
