Ischaemic stroke and intracerebral haematoma in the Waikato Stroke Registry.
OBJECTIVE
to determine the incidence and outcome of ischaemic stroke and intracerebral haematoma in a hospital stroke registry.


METHODS
this was a prospective observational study in a base hospital with catchment population of 205,000. We sequentially sampled 195 persons age 60+ admitted to Waikato Hospital with definite or probable ischaemic stroke or intracerebral haematoma. We assessed Barthel activities of daily living (ADL) scores prior to stroke and at days seven, 30 and hospital discharge. We measured mortality at days seven and 30.


RESULTS
One hundred and thirty-three of the 195 subjects (68%) had early CT brain scans. Compared to subjects who were scanned, those not scanned were significantly older, more dependent prior to stroke, less likely to be alert at the time of admission and had a higher mortality. Age, prestroke dependency and level of consciousness were independent predictors of scanning in a multiple logistic regression model. Among subjects who had CT brain scans, 12% had intracerebral haematoma and 88% had ischaemic stroke. The group with ischaemic stroke were significantly older, more often alert on admission and had lower mortality than those with intracerebral haematoma. Survivors in both groups had similar functional outcome as measured by Barthel ADL scores.


CONCLUSIONS
twelve percent of elderly subjects who had CT scanning following hospital admission for acute stroke syndrome had intracerebral haematoma. This group had a much higher mortality than the remaining 88% with ischaemic stroke. Functional outcome among stroke survivors in both groups did not differ. The incidence of intracerebral haematoma among subjects with CT proven stroke in New Zealand was similar to that found in hospital based surveys in other western countries.
