Abstract

OBJECTIVES:

To investigate whether the National Institutes of Health Stroke Scale (NIHSS) can be used to predict mortality and functional outcome in patients presenting with intracerebral haemorrhage.

DESIGN:

Retrospective study of a prospectively collected cohort.

SETTING:

Regional hospital, Hong Kong.

PATIENTS:

A cohort of 359 patients presented to our hospital from 1996 to 2001 with their first-ever stroke and intracerebral haemorrhage.

MAIN OUTCOME MEASURES:

The sensitivity and specificity of the NIHSS with a cut-off point of 20 in predicting mortality at 30 days and 5 years, and a favourable functional outcome at 5 years.

RESULTS:

A total of 359 patients were available for analysis and were divided into three subgroups according to the site and the size of the haematoma. The NIHSS can predict 30-day mortality with a sensitivity of 81% [corrected] and a specificity of 90% [corrected] The NIHSS can predict 5-year mortality with a sensitivity of 57% [corrected] and a specificity of 92% [corrected] In predicting favourable functional outcomes at 5 years, the NIHSS had a sensitivity of 98% [corrected] and a specificity of 16% [corrected]

CONCLUSIONS:

The NIHSS performed on admission can be used to predict mortality at 30 days and 5 years as well as favourable functional outcome at 5 years, all with an acceptable sensitivity and specificity.
