Highlights
- •Seizures are a significant complication of aneurysmal subarachnoid haemorrhage.
- •Antiseizure medication is often used in the prevention of seizures in subarachnoid haemorrhage.
- •There is insufficient evidence to support recommendations concerning antiseizure medications in subarachnoid haemorrhage.
- •Robust trial data are urgently needed to inform best practice guidelines.
Abstract
Our objective was to describe antiseizure medication (ASM) prescription patterns,
and associations between ASM use and death and disability outcomes in patients with
aneurysmal subarachnoid haemorrhage (aSAH) admitted to ICU. This was a multi-centre
prospective observational study. The study took place in eleven ICUs across Australia
and New Zealand. Data was collected from 1 April 2017 to 1 October 2018. Three hundred
and fifty-seven adult patients with aSAH were enrolled. The primary outcome was to
describe patterns of ASM prescription. The secondary outcome of interest was death
or disability (modified Rankin Scale (mRS) score ≥ 4) at six months, and its association
with ASM therapy, and relevant clinical subgroups. Forty percent of patients received
an ASM and the most commonly used agent was levetiracetam. The median length of ASM
administration was eight days (IQR 4.5–12.5). A number of patients with prehospital
seizures did not receive ASM therapy (14/55, 2725%). There was a tendency towards
ASM prescription with both higher radiological and clinical grade aSAH. There was
no significant association between death or disability at six month (mRS ≥ 4) and
ASM vs No ASM prescription. Testing for an interaction effect between ASM administration
and WFNS grade suggested inferior outcomes with ASM use in lower aSAH grades (p = 0.04).
In conclusion, the prescription of ASM for aSAH in Australia is variable across and
within sites, with the majority of patients not receiving ASM chemoprophylaxis. We
demonstrated no significant association between death or disability at six months
and the use of ASM. There may be an association with poorer outcomes in patients with
lower grade aSAH. This finding requires further exploration.
