Objective To evaluate direct transfer to the angiosuite protocol of patients with acute stroke, candidates for endovascular treatment (EVT). Methods We studied workflow metrics of all patients with stroke who had undergone EVT in the past 12 months. Patients followed three protocols: direct transfer to emergency room (DTER), CT room (DTCT) or angiosuite (DTAS, only last 6 months if admission National Institute of Health Stroke Scale (NIHSS) score >9 and time from onset <4.5 hours) according to staff/ suite availability. DTAS patients underwent cone-beam CT before femoral puncture. Dramatic clinical improvement was defined as 10 NIHSS points drop at 24 hours. Results 201 patients were included: 87 DTER (43.3%), 74 DTCT (36.8%), 40 DTAS (19.9%). Ten DTAS patients (25%) did not receive EVT: 3 (7.5%) showed intracranial hemorrhage on cone-beam CT and 7 (17.5%) did not show an occlusion on angiography. Mean door-to-puncture (D2P) time was shorter in DTAS (17+8 min) than DTCT (60+29 min; p<0.01). D2P was longer in DTER (90+53 min) than in the other protocols ( p<0.01). For outcome analyses only patients who received EVT were compared; no significant differences in baseline characteristics, including time from symptom-onset to admission, puncture-torecanalization, or recanalization rate, were seen. However, time from symptom-to-puncture (DTAS: 197 +72 min, DTER: 279+156, DTCT: 224+142 min; p=0.01) and symptom-to-recanalization (DTAS: 257+74, DTER: 355+158, DTCT: 279+146 min; p<0.01) were longer in the DTER group. At 24 hours, there were no differences in NIHSS score ( p=0.81); however, the rate of dramatic clinical improvement was significantly higher in DTAS: 48.6% (DTER 24.1%, DTCT 27.4%); p=0.01). An adjusted model pointed to shorter onset-to-puncture time as an independent predictor of dramatic improvement (OR=1.23, 95% CI 1.13 to 133; p<0.01) Conclusion In a subgroup of patients direct transfer and triage in the angiosuite seems feasible, safe, and achieves significant reduction in hospital workflow times.
