Early management and outcome of acute stroke in Auckland

Abstract

Background: Studies of acute stroke management in stroke units and tertiary referral hospitals may not accurately reflect practice within the population. Reliable information on the management of stroke within a population is sparse.

Aims: To compare clinical practice in acute stroke management in Auckland with guidelines for the management and treatment of stroke in other countries; to provide a baseline measure against which future changes in management can be evaluated.

Methods: All new stroke events in Auckland residents in 12 months were traced through multiple case finding sources. For each patient, a record of investigations and treatment during the first week of hospital admission was kept.

Results: One thousand eight hundred and three stroke events (including subarachnoid haemorrhages) occurred in 1761 patients in one year. Twenty-seven per cent of all events were managed outside hospital and 73% of the stroke events were treated in an acute hospital. Of the 1242 stroke events admitted to an acute hospital in the first week, only 6% were managed on the neurology and neurosurgery ward, 83% were managed by a general physician or geriatrician and 42% had computed tomography (CT). Of 376 validated ischaemic strokes, 44% were treated with aspirin and 12% with intravenous heparin. Of the 690 unspecified strokes (no CT or autopsy), 38% received aspirin and 0.5% heparin. The 28 day in-hospital case fatality for all stroke events admitted to an acute hospital during the first week was 25%.

Conclusions: In Auckland, management of acute stroke differed from clinical guidelines in the high proportion of patients managed in the community, the low rate of neurological consultation, and the low frequency of CT scanning. Despite these deficiencies in management, the 28 day hospital case fatality in Auckland was similar to other comparable studies which had a high proportion of cases evaluated by a neurologist and CT.
