Fast decisions, clear guidance: a qualitative study of trauma aid design

Although trauma clinical guidance has the potential to improve patient outcomes significantly, it is applied inconsistently across the USA today. Work is needed to improve guidance application among those who treat traumatic injury, including emergency medicine (EM) clinicians. A priority step of such improvement is the visual design of clinical directives, as it can markedly influence EM clinicians' satisfaction and subsequent usage of guidance. This qualitative study aims to analyze EM clinicians' needs and preferences for the visual design of trauma clinical guidance.

As part of a larger exploratory sequential mixed-methods study exploring trauma clinical guidance barriers and facilitators, we conducted semistructured video conference interviews during August and September 2024 with EM clinicians. Participants were selected through purposeful criteria and snowball sampling to ensure diverse representation across professional and personal characteristics. Interviews were audio recorded and analyzed through rapid qualitative content analysis.

12 EM clinicians completed interviews, providing feedback on their preferences for the visual design of trauma clinical guidance. Clinicians emphasized the need for simple guidance that can be easily used in a time-pressured setting. Dynamic features such as expandable or "clickable" content can provide deeper explanations of guidance concepts without compromising usability. Flowsheets and visual aids can clarify guidance recommendations. Clinicians asked that recommendations be specific and action-oriented.

When designing trauma clinical guidance, authors should promote visual design characteristics that prioritize simplicity, dynamic features, visual aids, and specificity.
