| description | Since the clinical distinction between haemorrhagic and ischaemic stroke cannot be achieved with a simple clinical evaluation, and it is virtually impossible to submit all stroke patients to CT, a weighted clinical score may offer some advantages to physicians who are involved in stroke management. The Allen score (also referred to as the Guy's Hospital score), a validated clinical score, has been tested in two different clinical settings, comprising 289 patients. When only the values under 4 and those over 24 are taken into account (i.e. greater than 90% probability of ischaemia and haemorrhage), the global accuracy of the score is 97%, and the diagnostic gain (given a pretest probability for haemorrhage of 11% and a likelihood ratio of 194) is 85%. Therefore, we conclude that this simple clinical method can be used for epidemiological studies of stroke incidence and outcome, as well as for a first bedside screening to decide which patients should have priority for CT. |
