title: Delayed diagnosis in subarachnoid haemorrhage.
abstract: OBJECTIVE
  To determine the outcome in patients with subarachnoid haemorrhage from a ruptured aneurysm, particularly in those in whom the diagnosis was delayed.
  
  
  METHODS
  A two-year retrospective study of medical records of patients admitted to Westmead Hospital between July 1988 and June 1989.
  
  
  METHODS
  A tertiary level teaching hospital.
  
  
  METHODS
  Ninety-four patients treated for subarachnoid haemorrhage. In 15 cases the diagnosis was delayed.
  
  
  METHODS
  Death, disability, or functional recovery.
  
  
  RESULTS
  Overall, 40 (42.5%) patients died, 14 (15%) were disabled, and 40 made a functional recovery. Of the 62 patients who were treated surgically 38 (61%) made a functional recovery compared with two of the 32 (6%) who were not. Of the 15 in whom the diagnosis was delayed seven (47%) made a functional recovery. Confirmation of the diagnosis was delayed in four of the latter group because a cranial computed tomography scan showed no abnormalities.
  
  
  CONCLUSIONS
  Earlier diagnosis, allowing early definitive surgical treatment, may improve the outcome in aneurysmal subarachnoid haemorrhage. The results of a computed tomography scan are diagnostic only if they are positive--a negative result must be interpreted in conjunction with the clinical picture.
