According to Donabedian’s theoretical framework for quality of healthcare.
Stroke specialists are physicians with special skills in stroke such as neurology, neurosurgery, and rehabilitation medicine.
TSC is defined with the presence of stroke unit, the presence of stroke specialists, and performing more than 15 EVT procedures per year according to the criteria of TSC in Joint Commission.
