Abstract only Introduction: The prevalence of stroke is progressively increasing in developing countries owing to the increase in vascular risk factors in the population. Risk factors vary significantly in different population groups leading to variations in disease progression, management and outcomes. This study aims to describe the epidemiology, prevalent risk factors and outcomes in a multi ethnic society of Qatar. Methods: We conducted a retrospective cohort study that included all patients with suspected stroke admitted to Hamad General Hospital, Doha Qatar between April 30, 2014 till September 15, 2020. Results: A total of 11,892 patients were admitted during this period with suspected stroke. Of these, Ischemic stroke (IS; 48.8%), Transient ischemic attack (TIA; 10.3%), Intracerebral hemorrhage (ICH; 10.9%), Stroke mimics (28.6%) and Cerebral venous sinus thrombosis (CVST; 1.3%). Mean age was 53.1 + 14.1 and a male to female ratio of 3:1. Study population was majorly Asian (56.8%) and Arab (36%); while African (4.5%), Caucasian (2.6%) and Others (0.1%) formed minority of the population. Asian population (South Asian; 49.7 + 11.6 and Far Eastern; 47.4 + 9.9) were younger as compared to Arabs (58.9 + 15.9). Majority of the patients were hypertensive (66.8%), diabetic (47.9%) and dyslipidemic (45.9%) on admission, while cardiac diseases (14.7%) and DVT (0.3%) were observed in fewer patients. Patients with a history of prior stroke were 11.7%, while 0.9% had a prior TIA. In IS patients, 31.7% of the patients arrived ED within the 4.5-hour thrombolysis window, 12.5% received thrombolysis and 4.6% received thrombectomy. The average Door-to-Needle time for IS patients was 58.9 + 39.5 minutes. The average length of stay was 5.2 + 9.0 days with 71.5% discharged home, 13.8% transferred to rehabilitation, 9.3% to other specialties, 3% to long term care and 2.4% suffered in-hospital mortality. Conclusion: The patients suffering Stroke in Qatar are relatively younger than western population. Highly prevalent vascular risk factors could explain younger presentation and relatively high burden of stroke. Further analysis of epidemiological differences between ethnic subgroups can help tailoring effective preventive and management policies to reduce the burden of disease.
