Quality of Telemedically Guided Prehospital Analgesia

Ambulances in the EMS of the city of Aachen are equipped with a portable telemedicine system. In emergencies requiring intravenous analgesia paramedics can use this system to contact the tele-EMS physician with an audio-connection. Vital parameters (e.g., ECG, pulse oximetry, non-invasive blood pressure) can be transferred in real-time. The transmission of still pictures - taken with an official smartphone - and video streaming from the inside of the ambulance are also possible. The tele-EMS physician supports the paramedics and can delegate the application of morphine and other analgesics based on two predefined algorithms for trauma and non-trauma cases that are displayed on a context-sensitive telemedical documentation system in the teleconsultation center.

This (control) group represents the conventional treatment in German emergency medical service (EMS). In addition to an ambulance manned with paramedics, a prehospital EMS physician is deployed to conduct analgesic treatment on-scene. Treatment data for this group are selected from the time period before implementing teleconsultation in routine and therefore represent a historical control group.
