Transfer times for patients with extradural and subdural haematomas to neurosurgery in Greater Manchester.

Delay in transfer of patients with acute extradural (EDH) or subdural (SDH) haematoma to definitive neurosurgical evacuation has a detrimental effect on outcome. From July 2003 to December 2005 we undertook a prospective analysis of patients admitted to our unit for neurosurgical evacuation of their haematoma, who were transferred from non-neurosurgical hospitals. Data was collected for: 1) overall transfer time, 2) time taken from injury or deterioration to CT scan, 3) time from CT scan to arrival at our unit, and 4) time from arrival at our unit to surgery. Overall 81 patients were eligible, of which 39 had an EDH and 42 a SDH. The median transfer times for EDH and SDH were 5.25 hours and 6.0 hours respectively. This paper discusses the factors that may prolong delays in the transfer of patients between hospitals and the way in which our unit is trying to improve the local service for the population of Greater Manchester.
