    Spontaneous subarachnoid haemorrhage (SAH) requires urgent diagnosis to manage potential cerebral aneurysms and improve patient outcomes.

  • 2

    Lumbar puncture (LP) is traditionally used to diagnose SAH when CT scans are negative, but recent NICE guidelines recommend against routine LP.

  • 3

    The study aimed to evaluate the impact of new NICE guidelines on the diagnosis of SAH and quantify missed diagnoses due to changes in LP practices.

  • 4

    Data were collected from 25 out of 31 neurosurgical centers in the UK and Ireland, focusing on SAH cases diagnosed via LP after negative CT scans.

  • 5

    Statistical analysis assessed changes in diagnostic practices for SAH, including the frequency of LPs performed post-NICE guideline implementation.
