Socio-demographic profile, past medication history, clinical presentation, drugs prescribed for comorbid condition and stroke treatment, and outcomes data were collected using data abstraction formats and results were summarized using both descriptive and inferential statistics.Key Findings: According to WHO clinical criteria, 89 (80.2%) were diagnosed with ischemic stroke, and 20 (18.0%) were diagnosed with hemorrhagic stroke. The majority of the patients 94 (84.7%) had at least one antecedent risk factor in which hypertension accounted for 44.1%. More than half, 69 (62.2%), of hospitalized stroke patients had good treatment outcomes while 42 (37.8%) had a poor outcome. The overall case-fatality rate was 18 (16.2%), 12 (13.5%) from ischemic stroke, and 6 (30.0%) from hemorrhagic stroke. Acetyl salicylic acid (ASA) with atorvastatin/simvastatin, 67 (73.5%) in ischemic stroke and 12 (60.0%) in hemorrhagic stroke, was the most frequent medications prescribed for stroke during admission while it was frequently prescribed for 48 (53.6%) of ischemic stroke and 10 (50.0%) of the hemorrhagic stroke on discharge. Overall, ceftriaxone + metronidazole 32 (28.8%) was frequently prescribed concomitant medications during admission. The major predictors identified for poor stroke outcomes were substance abuse (AOR=2.839, P=0.024) and have had not received any medication for stroke treatment during admission (AOR=12.503, P≤ 0.001).Conclusion: A significant number of the admitted stroke patients had poor treatment outcome in which the case-fatality rate was relatively high. Substance abuse and having not received medication for stroke were the significant predictors for poor treatment outcome. Hence, a well-established stroke unit setup at AURH is required for accurate diagnosis and management of stroke to overcome stroke-related mortality and/or poor treatment outcome.Keywords: stroke, predictors, outcomes, Ambo, Ethiopia
