title: Validation of the use of the ROSIER stroke recognition instrument in an Irish emergency department.
abstract: 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).
  
  
  CONCLUSIONS
  The ROSIER is a suitable and useful adjunct in the assessment of stroke patients in Ireland.
