How well do we investigate patients with suspected subarachnoid haemorrhage? The continuing need for cerebrospinal fluid investigations.
OBJECTIVE
To demonstrate the extent of compliance with established guidelines for the investigation of suspected subarachnoid haemorrhage (SAH) and the implications of non-compliance.


METHODS
Prospective observational study of practice in three hospitals in the Trent region.


METHODS
One teaching hospital with a tertiary neuroscience referral centre and two large district general hospitals.


METHODS
50 consecutive patients from each centre referred for suspected SAH with negative computed tomography.


METHODS
Diagnosis of SAH confirmed or excluded according to guidelines.


RESULTS
When the data from the three centres were combined (n = 150 computed tomography negative cases) cerebrospinal fluid (CSF) investigation was not performed in 60/150 (40%). In the 90 cases where CSF studies were performed SAH was confirmed in 11 (12%).


CONCLUSIONS
There is significant non-compliance in following the established guidelines for the investigation of SAH at the centres studied. As the primary cause of non-traumatic SAH is ruptured aneurysm, which is associated with high morbidity and mortality from second haemorrhage, this highlights a major source of concern for clinical governance.
