New clinical decision rule to exclude subarachnoid haemorrhage for acute headache: a prospective multicentre observational study

Conclusions While maintaining equal sensitivity, our new rule seemed to offer higher specificity than the previous rules proposed by the Ottawa group. Despite the need for blood sampling, this method can reduce unnecessary head CT in patients with acute headache. Trial registration number UMIN 00004871.
