简要总结
Prehospital stroke care in specialized ambulances increases thrombolysis rates, reduces alarm-to-treatment times, and improves prehospital triage. Preliminary analyses suggest cost-effectiveness. However, scientific proof of improved functional outcome compared to usual care is still lacking. The objective of this trial is to show improved functional outcomes after deployment of the Stroke Emergency Mobile (STEMO) compared to regular care.
详细描述
This is a pragmatic, prospective, multi-center trial with blinded outcome assessment of treatment candidates three months after stroke. Treatment candidates will be defined as patients with final discharge diagnosis of cerebral ischemia, and onset-to-alarm time ≤4 hours, symptoms not resolved at time of ambulance arrival, and able to walk without assistance prior to emergency. These patients will be included if their emergency call from a predefined catchment area in Berlin, Germany, caused a stroke alarm at the dispatch center during STEMO hours (7am-11pm, Monday-Sunday). About 45% of STEMO dispatches will be handled by regular ambulances since STEMO will be already in operation creating the quasi-randomized control group.
B_PROUD uses data from the B-SPATIAL registry. The B-SPATIAL registry has started recruitment in January 2016. However, B_PROUD recruits patients with symptom onset October 1st, 2016 or later (because data access at the dispatch center had to be established first).

结局指标
主要结局
Modified Rankin Scale
时间窗: 3 months
Assessment of functional outcome over the entire range of the modified Rankin Scale
Co-primary 3-Month Outcome
时间窗: 3 months
The co-primary 3-month outcome includes the following range of outcomes: 1. mRS 1-3 if available 2. mRS 4-5 or (if mRS is missing) living in institution (information according registration office at 4 month after stroke) 3. death. We will run a sensitivity analysis with the co-primary outcome and calculating all patients with missing mRS but still living under private address as mRS 1-3. The latter will help us to include information of patients still living at home but without mRS follow-up. All outcomes will be calculated with ordinal logistic regression.
