Highlights ■ Teleconsultation reduced on-scene time from 36.8 to 20.6 min (p=0.019). ■ Video-based prearrival anamnesis improved team efficiency. ■ Interventions and clinical profiles were similar across the groups. ■ Study supports broader telemedicine adoption in emergency care. ABSTRACT Objective: Ambulance transport time is an important metric in prehospital care. Limited studies have explored strategies to decrease on-scene time. We examined the effect of collecting telemedicine-based medical data during ambulance dispatch on the on-scene evaluation time of the prehospital team. […]
