Emergency care from the tele-emergency service or tele-stroke unit

In medical emergencies, every second often counts when it comes to saving lives or avoiding permanent damage. However, in rural regions in particular there is a lack of emergency doctors or specialized stroke units in hospitals. Telemedicine can be used to improve patient care in emergencies. To that end, tele-emergency doctors in control centers support the emergency responders at the scene. They help make diagnoses and direct the treatment remotely. As a result, appropriate care can be provided in many emergencies, such as blood pressure derailments, with the support of a tele-emergency doctor.

Furthermore, many regional hospitals that do not have a permanent neurologist on site are now digitally connected to larger specialized clinics. This enables cooperation with the stroke unit in the larger hospital so stroke patients can be appropriately treated in regional hospitals with the aid of telemedicine. In Germany, almost one in ten stroke patients are already treated using telemedicine.

When an ambulance is sent to an emergency, there is often no doctor on board. The control center uses the caller’s information to determine whether to request an emergency doctor in addition to the paramedics. The emergency doctor drives to the scene independently of the ambulance and often arrives later. In many situations, it can also be useful for a tele-emergency doctor to remotely support the emergency responders at the scene.

In Germany, paramedics have limited powers to treat patients and administer medication. By involving a tele-emergency service, the emergency situation can be assessed and the necessary treatment can be provided quickly and safely. The tele-emergency doctor is responsible for the treatment initiated.

In rural regions in particular there are often only a few emergency medical centers, which have to cover large areas. To nevertheless enable rapid medical assessments and treatments in emergencies, a growing number of municipalities are setting up tele-emergency services to support the conventional emergency services.

How does assistance from tele-emergency doctors work?

Tele-emergency doctors provide the emergency responders at the scene with remote medical and organizational support. They are connected to the ambulance by a live feed that provides both video and sound. Conversely, the emergency responders can give tele-emergency doctors important information and data about patients’ blood pressure, heart function (ECG) and breathing. This cooperation enables the tele-emergency doctor to provide the emergency responders at the scene with advice and guidance as they assess the emergency situation and instigate treatment. 

What are the duties of a tele-emergency doctor?

The main duties of a tele-emergency doctor include offering advice and guidance to the emergency responders at the scene. Tele-emergency doctors can:

• help make diagnoses
• approve treatments, such as the administration of medication
• retrospectively order an emergency doctor to the scene if required (in consultation with the emergency services)
• assist the emergency doctor at the scene with decisions
• notify the hospital of a patient’s arrival
• provide advice and support during onward transportation and patient transfers to another hospital

For what kinds of emergencies can tele-emergency services provide assistance?

In emergencies where there is no acute risk to life, the main roles of an emergency doctor include providing a medical assessment, prescribing treatments, for example through medication, or deciding whether a patient should be transported to the hospital. These tasks can also be performed by the tele-emergency services. Examples of areas in which tele-emergency services can provide support therefore include:

• blood pressure derailments
• hypoglycemia
• pain management for non-life-threatening injuries
• strokes not involving a loss of consciousness

Studies and the experience gained from medical care to date have shown that tele-emergency services are able to provide the same (if not a better) level of medical care for non-life-threatening emergencies as emergency doctors at the scene.

Do tele-emergency doctors require special training?

Tele-emergency doctors are experienced, specially trained medical practitioners. Prior to working for tele-emergency services, a doctor must have attended more than 500 emergencies in person and acquired additional qualifications in emergency medicine. Doctors are appropriately trained before they can work as tele-emergency doctors.

A stroke is a medical emergency in which rapid diagnosis and treatment are particularly decisive with regard to how the condition will progress. To ensure that stroke patients receive the best possible medical care, many larger hospitals therefore have a specialized stroke unit. Such stroke units have highly qualified teams of doctors and nurses as well as special diagnosis and treatment options.

Smaller, regional hospitals, on the other hand, do not always have a stroke unit or similar specialist department and are therefore unable to ensure the provision of special stroke care around the clock. As a result, a growing number of them are joining together to form telemedical networks.

What is a tele-stroke unit?

A tele-stroke unit remotely supports the medical care of stroke patients. The medical experts from the large hospitals with a stroke unit are available 24 hours a day. Thanks to their support, even hospitals without a stroke unit or on-site neurologist can ensure the provision of a high level of stroke care. Germany now has over 20 telemedical networks, involving over 200 hospitals/clinics. 

How do tele-stroke units work?

The neurological experts from a tele-stroke unit use digital media to advise and support the attending doctors. The experts can therefore get involved in both examining and treating the patients. For example, with the support of the on-site doctor, they can use a remote-controlled, high-resolution camera to perform examinations remotely. This makes it possible to jointly determine and initiate the best form of treatment. This often eliminates the need for transportation to a more distant hospital with a stroke unit. In some cases, however, transportation to a larger hospital is still necessary, for example for special interventions.
