Abstract
Background Spontaneous aneurysmal subarachnoid hemorrhage (SAH) is a common neurosurgical emergency
with a high case fatality rate. The clinical course of SAH generates high health economic
expenses. Here we highlight possible cost-driving factors for in-hospital care expenses
for the first year. Furthermore, results are compared with ischemic stroke treatment.
Methods One hundred and one patients with aneurysmal SAH treated in our hospital from 2007
through 2009 were included. The Hunt and Hess (HH) scale, World Federation of Neurosurgical
Societies (WFNS) scale, Fisher Scale, and further outcome-relevant data were recorded.
Expenses were calculated using the German fixed case rate classification system consisting
of Diagnosis-Related Groups (DRG) and the Operation and Procedure catalogue (OPS).
Overall acute length of stay (LOS) and LOS on the intensive care unit (ICU) were separately
evaluated. Expenses were compared with formerly published first-year costs of ischemic
stroke.
Results Fifty-four percent of the patients (median age 52 years, 69% females) received coiling
and 46% clipping. Acute in-hospital treatment accounted for 82% of total in-hospital
expenses, while consequential in-hospital treatment accounted only for 18%. Altogether,
the total first-year in-hospital expenses for all patients were as high as €2,650,002,
resulting in average SAH in-hospital treatment expenses of €26,238 per patient for
the first year. Poor clinical condition on admission and longer stay in ICU are the
main cost-driving factors. The impact of the aneurysm treatment method is debatable.
Only a poor HH grade and longer ICU stay are independent cost-driving factors. SAH
treatment expenses are far higher than treatment costs for ischemic stroke in the
literature (€6,731 for first-year inpatient and €3,287 for outpatient treatment).
Conclusions Clinical condition and LOS determine in-hospital expenses after SAH. Aneurysmal SAH
prevalently results in a relevant economic impact on the health system exceeding formerly
published treatment expenses for ischemic stroke.
