Pilot Evaluation of a SmartPhone Application for Teamwork and Communication in Trauma 'inthe Wild'.

Disruptions along the trauma pathway that arise from communication, coordination, and handoffs problems can delay progress through initial care, imaging diagnosis, and surgery to intensive care unit (ICU) disposition. Implementing carefully designed and evaluated information distribution and communication technologies may afford opportunities to improve clinical performance. This was a pilot evaluation “in the wild” using a before/after design, 3 month, and pre- post-intervention data collection. Use statistics, usability assessment, and direct observation of trauma care were used to evaluate the app. Ease of use and utility were assessed using the technology acceptance model (TAM) and system usability scale (SUS). Direct observation deployed measures of flow disruptions (defined as “deviations from the natural progression of an procedure”), teamwork scores (T-NOTECHS), and treatment times (total time in emergency department [ED]).
