![]() Understanding the range of current practice patterns is an important first step toward that goal. Given the overall importance of prethrombectomy workflow on time to treatment, improved guidance is needed for hospitals looking to redesign their own systems to care for patients with LVO. In the absence of such consensus, individual centers have implemented a heterogeneous assortment of workflows that may be influenced by individual physician preference, institution-specific factors, or incomplete awareness of effective solutions at competing institutions. 7, 18 ⇓– 20 Although many of these efforts have been successful, there is currently no broadly accepted consensus for optimal prethrombectomy workflow. These developments have sparked considerable interest in designing efficient workflows for diagnosis and treatment that can reduce the time between patient presentation and thrombectomy. 6 ⇓ ⇓ ⇓ ⇓– 11 Indeed, the negative results of 3 earlier clinical trials 12 ⇓– 14 may be attributed in part to prolonged treatment delays. 1 ⇓ ⇓ ⇓– 5 For these patients, the likelihood of a good neurologic outcome depends on the time elapsed between symptom onset and revascularization. Recent clinical trials have conclusively demonstrated the outcome benefit of mechanical thrombectomy in selected patients with acute ischemic stroke caused by large vessel occlusion (LVO).
