Background:
A study was performed to determine the utility of the 8-point recognition of stroke in the emergency room (ROSIER) instrument as a diagnostic tool in a large Irish emergency department.
Methods:
Fifty patients had ROSIER scores completed by doctors. Diagnoses achieved using the score were compared with discharge diagnoses. Relations between ROSIER score, impairment and length of stay were assessed.
Results:
Forty-seven patients (94%) had a ROSIER Score > or =1 indicating a stroke, 44 (94%) of these had stroke confirmed on investigation. Two patients with stroke were missed and three were wrongly identified. Positive predictive value for the ROSIER was 94%. ROSIER correlated with Scandinavian neurological stroke score. (r = -0.414, p = 0.003) and was associated with increasing length of stay in survivors (p = 0.16, one-way ANOVA. F = 3.116, df = 6).
Conclusion:
The ROSIER is a suitable and useful adjunct in the assessment of stroke patients in Ireland.
