Impact of a direct-admission stroke pathway on delays of admission, care, and rates of intravenous thrombolysis

IntroductionThis study examined the impact of a “direct potential thrombolysis” pathway with direct admission to a neurological stroke unit (SU) on delays of admission, stroke care and proportion of patients with ischemic stroke (IS) treated with intravenous (IV) rtPA.MethodsThis prospective study included all patients admitted in the intensive SU for potential thrombolysis over a 2-month period. Data collected included the time of symptom onset, mode of transport, National Institutes of Health Stroke Scale (NIHSS) score on arrival, delays of care, delays of imaging and modalities, diagnosis and therapeutic data.ResultsDuring the 2-month study period, 81 patients (mean age of 65 years) were included in the study. The Emergency Medical Services (EMS) were involved in 86% of admissions, with a median delay of admission of 1 h 48 and access within 4.5 h in 84% of cases. Every patient underwent immediate neurovascular assessment and imaging examination, which was a MRI in 80% of cases. Only 70% of patients had a final diagnosis of stroke. Intravenous rtPA therapy was administered to 26 patients (32%), and 58% of patients with IS. The median door-to-needle time delay was 63 min.ConclusionA direct 'potential thrombolysis' pathway, based on EMS and located in the SU, can result in earlier admission, reaching the recommended care delay, and a large proportion (58%) of IS patients receiving rtPA therapy. On the other hand, the proportion of patients with stroke mimics is high, thereby increasing the chances of intermittent periods of saturation of this specific pathway.
