[Effects of the prehospital care with and without suspecting acute stroke: a single stroke center study].

We retrospectively examined the differences between paramedic triage and final diagnosis in the cases that were transported to our hospital between May 2016 and March 2019. About 30% of the patients with suspected stroke were diagnosed other than stroke. Some of the patients without suspected stroke were diagnosed with large vessel occlusion and were treated with mechanical thrombectomy. The time from arrival at the hospital to treatment was significantly longer in the patients without suspected stroke than with suspected stroke. To achieve a better prehospital care, we need to accept a wide range of stroke mimics, and to continuously feedback the paramedics about the importance of paralysis, cortical symptoms in stroke.
