About this study
The aim of the study is to investigate the quality of prehospital emergency care in acute stroke, when paramedics are supported telemedically by an EMS physician.
Read the detailed description
Six ambulances from five different Emergency Medical Service (EMS) districts are equipped with a portable telemedicine system. In cases of suspected acute stroke (including intracranial hemorrhage), the paramedics can use this system to contact a so called "tele-EMS physician" after consent of the patient is obtained. The tele-EMS physician has an audio-connection to the EMS team and receives vital parameters (e.g., ECG, pulse oximetry, non-invasive blood pressure) in real-time. The transmission of still pictures (taken with a smartphone), 12-lead-ECGs and video streaming from the inside of the ambulance can also be carried out, if indicated. The tele-EMS physician supports the EMS team in obtaining all relevant medical history, neurological diagnosis, general diagnosis and can delegate the application of medications. This can be carried out to bridge the time to the arrival of an EMS physician or in less severe cases without an EMS physician on-scene. The quality of prehospital care and the possible influences on the initial inhospital phase should be investigated and compared with regular EMS.

Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Quality of prehospital care (time frame: average 1 hour). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Sep 2015; AzTrials last refreshed its copy on 6 Nov 2026.
