title: The SOAR stroke score predicts inpatient and 7-day mortality in acute stroke.
abstract: OBJECTIVE
  An accurate prognosis is useful for patients, family, and service providers after acute stroke.
  
  
  METHODS
  We validated the Stroke subtype, Oxfordshire Community Stroke Project Classification, Age, and prestroke Rankin stroke score in predicting inpatient and 7-day mortality using data from 8 National Health Service hospital trusts in the Anglia Stroke and Heart Clinical Network between September 2008 and April 2011.
  
  
  RESULTS
  A total of 3547 stroke patients (ischemic, 92%) were included. An incremental increase of inpatient and 7-day mortality was observed with increase in Stroke subtype, Oxfordshire Community Stroke Project Classification, Age, and prestroke Rankin stroke score. Using a cut-off of ≥3, the area under the receiver operator curves values for inpatient and 7-day mortality were 0.80 and 0.82, respectively.
  
  
  CONCLUSIONS
  A simple score based on 4 easily obtainable variables at the point of care may potentially help predict early stroke mortality.
