Automatic emergency calls from smartphone/smartwatch applications in trauma

Dear Editor, Timely access to care is essential for severely injured trauma patients. 1 Some modern smartphones (iPhone 14; Apple Inc.) and smartwatches (Apple Watch Series 8; Apple Inc.) are equipped with crash detection systems, which are designed to detect shocks associated with car collisions and automatically send out emergency calls, resulting in immediate activation of the emergency medical services (EMS) system. Among 27 cases that were unresponsive, the ambulance was sent in 12 cases; among them, 3 victims were transported to the hospital, and 15 erroneous calls were confirmed to be false crashes. CONFLICT OF INTEREST STATEMENT The authors declare no conflicts of interest.
