BACKGROUND: Mobile technology can aid in healthcare decision-making at the point of care. We created a Web-based trauma-specific smartphone application containing links to local protocols and national organization guidelines for trauma providers. We hypothesized that smartphone access to these guidelines would facilitate application of knowledge in a timely fashion.

MATERIALS AND METHODS: Trauma providers were randomized to have or not have access to their smartphone during a timed, 10-question examination of trauma scenarios based on Eastern Association for the Surgery of Trauma, Western Trauma Association, and local protocols. Participants were then surveyed regarding their experience with the application. Groups were compared based on time with completion and percentage of correct answers. Subgroup analyses were completed to assess the utility of the application.

RESULTS: Of 30 participants, 16 were randomized to smartphone use. Smartphone users took longer to complete the examination than nonusers (9:18 versus 6:36, P = 0.007) but answered a greater proportion of questions correctly (50% versus 40%, P = 0.159). Smartphone users had a higher percentage correct for Eastern Association for the Surgery of Trauma and Western Trauma Association protocol-based questions (78% versus 52%, P = 0.027; 70% versus 39%, P = 0.011), but no difference for local protocol-based questions (29% versus 37%, P = 0.48). Smartphone users who reported recent application use had the longest time to completion (11:44, P = 0.023) but the highest percentage correct (60%, P = 0.03).

CONCLUSIONS: Smartphone use among those familiar with our trauma application resulted in the highest percentage correct but increased times to completion. The application interface should be streamlined, and providers educated to improve usage and reduce time to access information.
