Practice Patterns and Barriers for Intravenous Thrombolysis: A Survey of Neurologists in Saudi Arabia

Only a small fraction of patients with acute ischemic stroke receive intravenous thrombolysis (IVT). We sought to assess barriers and practice patterns in using IVT for acute ischemic stroke among neurologists in Saudi Arabia. An electronic survey was sent to all neurologists registered with the Saudi Commission for Health Specialties. A total of 148 (77.5%) neurologists responded. The most common reported barriers for IVT administration were delayed presentation to hospitals (82.4%) and unclear time of symptom onset (50.0%). Only 9.9% of neurologists reported strict adherence to the American Heart Association/American Stroke Association guidelines for IVT administration. The most frequently waived criteria were “minor stroke with National Institutes of Health Stroke Scale [NIHSS] < 5” (49.4%) and “seizure at onset” (45.7%). For the extended 3–4.5-hour window, 18.5% of neurologists reported strict adherence to the four exclusion criteria. The most frequently waived criteria were “age older than 80 years” (53.1%) and “history of both diabetes and prior stroke” (42.0%). In conclusion, most neurologists do not adhere to the IVT exclusion criteria. However, little consensus exists regarding which criteria do not interfere with IVT administration. Barriers to IVT administration were identified and require immediate action by healthcare authorities in Saudi Arabia.
