Acute stroke centre - the changing focus of stroke unit care. The Bergen NORSTROKE Study

摘要

Objectives- The basic stroke unit studies selected patients primarily for rehabilitation and did not deal with the critical first hours after stroke. The aim of this study was to analyse a unselected cohort of patients admitted to an acute stroke centre with primary focus on emergency diagnosis and treatment. Materials and Methods- All patients with suspected stroke were admitted as emergencies. Patients with definite cerebrovascular disease were prospectively included in the Bergen Stroke Study, patients with other diseases were excluded, but final diagnosis was registered. Results- Fifty per cent of the admitted patients had other diagnosis than stroke. Of 1267 consecutive patients with cerebrovascular disease, 70% had no or minor neurological deficits on admission. After 1week, 56% were independent, 30% needed long-term rehabilitation, 10% were bedridden and 4% were dead. Conclusion- An acute stroke centre today requires a high degree of neurological expertise in assessing patients admitted with possible stroke. Most patients with stroke have no or mild deficits and need above all rapid diagnostic work-up, acute and prophylactic treatment. In-hospital rehabilitation is essential for a smaller number of patients who suffer from persisting neurological deficits after stroke.
