For patients with spontaneous subarachnoid haemorrhage, it remains to be investigated if there is an association between the time from patients call the Emergence Medical Coordination Center to neurosurgical admission and long-term outcome.

This is a retrospective cohort study with four-year followup. The primary aim is to determine if the time to neurosurgical admission is associated to labour marked affiliation and mortality after four years.

Inclusion Criteria:

• Spontaneous subarachnoid haemorrhage registered in the Danish National Patient Register and confirmed by medical record review.
• Initially admitted to a hospital in the Capital Region of Denmark between 1 January 2008 and 31 December 2014.

Exclusion Criteria:

• Prior subarachnoid haemorrhage.
• Inhospital symptom onset.

Patients that are retired or on social transfer payments the last three months before the sSAH are excluded from analyses on retirement and labour marked affiliation. However, they are included in mortality analyses. Also, patients aged 60 years or older are excluded in analyses of early retirement as reduced work capacity may to a higher degree result in early voluntary retirement.
