Systematic Reviews: Clinical Scenario
You are referred a 75 year old man with a stroke who had been admitted one day previously to general medicine. He has left-sided weakness and has difficulty with ambulating, bathing, feeding and dressing himself. He has hypertension which is well-controlled with a diuretic. He is otherwise well and you decide to transfer him to a stroke unit. His family is concerned because they live close to the hospital where he is currently as an inpatient and want to know why he needs to be transferred to a stroke unit of a different hospital and why he can't stay on the general medicine ward. You (with them) formulate the question: "In a patient with a stroke, does admission to a stroke unit decrease the risk of death and dependency?"
