Medical Information During Trauma Resuscitations: Are Smartphones the Contemporary Medical ID Bracelet?

Smartphone emergency medical identification (SEMID) applications are built-in health information-storing functions that are accessible without a passcode. The utility of these applications in the real-time resuscitation of trauma patients is unknown. We prospectively evaluated all trauma activation patients ≥16 y and unable to provide a medical history for any reason for the presence of a smartphone at our urban level I center between October 2020 and September 2021. Available smartphones were queried for SEMID utilization, categories of information contained, and real-time clinical relevance. One hundred and forty three patients with a median age of 39 y [interquartile range 28-59] and Injury Severity Score of 16 [2-29] were included. 30 (21%) patients arrived with a smartphone, 27 (90%) of which were accessible. 8 (30%) of those individuals utilized a SEMID application, and SEMID information was relevant for patient care in 6 cases (75%). The extracted information included: identifiers (75%), emergency contacts (50%), height/weight (38%), allergies (38%), age (38%), medications (25%), medical history (13%), and blood type (13%). Approximately one in five altered trauma patients have smartphones present at arrival, some of which contain medical information pertinent for immediate care. There is a pressing need for education and our institution has developed a publicly-facing campaign with shareable materials to improve SEMID awareness and utilization. Other centers are likely to find similar benefit.
