Objective: To identify predictors of in-hospital mortality in patients with aneurysmal subarachnoid hemorrhage (aSAH).

Methods: Retrospective analysis of prospective nationwide data from a multicenter registry on all aSAH cases admitted to a tertiary neurosurgical department in Switzerland between 2009 – 2014 (Swiss SOS). Patients admitted alive but dead at discharge (in-hospital mortality) were identified and both clinical and radiological predictors of death (adjusted odds ratios (aOR)) were identified using multivariate logistic regression analysis.

Results: Of n=1866 patients admitted alive with aSAH, in-hospital mortality was 20.0% (n=373) with death occurring within 48h of ictus in 35.7% (n=133). Independent predictors of in-hospital mortality at admission were uni- or bilateral pupil dilatation (aOR 3.68, 95%CI 2.33-5.83, p<0.001), followed by high WFNS grade (4 and 5; aOR 3.02, 95%CI 1.99-4.58, p<0.001), presence of intraventricular hemorrhage (aOR 2.66, 95%CI 1.73-4.09, p<0.001), age ≥ 60 years (aOR 95%CI 1.99, 1.36-2.89, p<0.001), and midline shift (aOR 1.61, 95%CI 1.03-2.53, p=0.039). Male patients were as likely as female patients to die (aOR 1.34, 95%CI 0.90-1.98, p=0.149). Patients not receiving curative therapy were more likely to die (aOR 14.11, 95%CI 9.16-21.73, p<0.001), as were patients with aneurysm re-bleeding (aOR 8.21, 95%CI 4.25-15.86, p<0.001), and those experiencing delayed cerebral ischemia (aOR 2.93, 95%CI 1.91-4.50, p<0.001). The rates of in-hospital mortality were 11.02% after a clipping and 12.55% after a coiling procedure. Finally, infarction on post-treatment CT scan was a predictor of death (OR 2.09, 95%CI 1.51-2.89, p<0.001).

Conclusion: The unselected nationwide database allows for accurate determination of the effect size of important predictors of in-hospital mortality. The highest independent risk factors were re-bleeding (aOR 8.21), pupil dilatation at admission (aOR 3.68) and high WFNS grade (aOR 3.02).
