Answer

Although controversy exists regarding the need for hospital admission, there is no controversy regarding the need for urgent evaluation, risk stratification, and initiation of stroke prevention therapy. [1, 36, 37, 26] When one community implemented a strategy to ensure patients were seen within an average of 1 day, compared with an average of 3 days, the 90-day stroke risk fell from 10% to 2%. [38]

Similarly, programs to admit patients to a "rapid evaluation unit" or "observation unit" have reduced the 90-day stroke risk from approximately 10% to 4-5%. [39, 40] Other authors have suggested similar benefits from rapid follow-up. [41]
