Overview
Brief Summary
Treatment of acute stroke must be fast. The aim of this trial is to show feasibility, safety and clinical benefit of a strategy of diagnosis and treatment directly at the emergency site for hyperacute treatment and transfer to the most appropriate target hospital. The effects on reduction delays until different stroke treatments will be assessed. First estimations of cost-effectiveness will also be performed.
Detailed Description
Stroke is a medical emergency for which "time-is-brain". Indeed, a huge body of animal experimental and clinical evidence exists that demonstrates that reducing the time to thrombolytic therapy is the most important variable in prevention of the disability. However, most stroke patients arrive to hospital too late for any type of acute stroke treatment: Only an estimated 19-60% of stroke patients present within 3 hours after symptom onset. Today, for stroke patients 3 different treatment options exist. 1. Thrombolysis with recombinant tissue plasminogen activator (rt-PA) is an effective treatment for many acute stroke patients as evidenced by several large randomized trials. 2. More recently, mechanical clot removal via catheters has been developed. There is currently increasing evidence that in obstruction of large brain vessels such endovascular treatment is superior to systemic thrombolysis in regard to recanalization rates and outcome. 3. Patients with intracranial hemorrhage can profit if transferred to hospitals with neurosurgical treatment options such as ventricular drainage or hematoma removal. However, each of these treatment are highly time sensitive and due the availability of endovascular and neurosurgical treatment options only in very few highly specialized neurovascular centres decision in which institution the patient should be transported is of high medical and financial relevance. The aim of this trial is to show feasibility, safety and clinical benefit of a strategy of diagnosis and treatment directly at the emergency site and its role in decision regarding transfer to appropriate target institution, thus potentially allowing reduction of time until treatment and delays until specialized treatment also in remote regions. First estimations of cost-effectiveness will also be performed.

Outcomes
Primary Outcomes
Proportion of stroke patients with accurate decision regarding transfer to the most appropriate target hospital
Time Frame: within 3 month
Secondary Outcomes
- Proportion of patients with haemorrhage being a) directly transferred to a neurovascular centre, and being b) evaluated/treated by a neurosurgeon.(within 3 month)
- Proportion of patients with large vessel occlusion a) being directly transferred to a neurovascular centre, and b) being evaluated/ treated by an interventionalist(within 3 month)
- Time between symptom onset/alarm and evaluation/treatment by an interventional radiologist in case of large vessel occlusion(within 3 month)
- Time between symptom onset/alarm and evaluation/treatment by a neurosurgeon in case of haemorrhage(within 3 month)
- Proportion of patients treated with rt-PA and time between symptom onset/ alarm and start of thrombolysis(within 3 month)
- Functional neurological status (mRS) (D7, D90)(within 3 month)
- Proportion of secondary transfers of stroke patients between primary stroke unit and neurovascular centre in all stroke patients, and in subgroups with ischemic and hemorrhagic stroke(within 3 month)
