Chinese Stroke Association guidelines on emergency stroke unit

Organised stroke care has become a keystone in delivering efficient and effective treatment to patients with stroke with improved outcomes. Delivering timely acute reperfusion therapy to those with acute ischaemic strokes is key to good recovery. Emergency stroke unit (ESU) is a novel organised stroke care system developed in China. It centralises all necessary procedures for the diagnosis and treatment of acute stroke into one unit that can perform clinical assessment, imaging examination and acute treatments. In ESU, artificial intelligence algorithms are used to aid in reading brain images and making clinical decisions. Therefore, ESU can significantly enhance the efficiency of emergent stroke care. In this guideline, we aim to clarify the concept, construction standards and personnel requirements of an ESU, standardise ESU-based acute stroke triage and treatment workflow, establish metrics of quality control, facilitate the construction and promotion of ESU and continue the improvement of the quality of stroke care.
