P112 Management and outcome of subarachnoid haemorrhage (SAH) in older people: a centre series

Abstract

ObjectivesTo study the management and factors associated with outcomes in SAH in elderly over 80 years of age.DesignRetrospective records review.SubjectsAll Patients with SAH confirmed on head CT admitted Jan 2012-Dec 2017.MethodsWe admitted 1079 patients with SAH, 32 were aged ≥80 y (3%). We subdivided the patients into a poor outcome group (POG) (Modified Rankin Scale (mRS) 4–6), (n=24, 14F/10M, mean age 83.7±0.7 y) and good outcome group (GOG) (mRS 0–3) (n=8, 7F/1M, mean age 82.6±0.6 y). Spearman’s rank-order test evaluated correlation between outcome (mRS) and all other variables (WFNS grade, GCS, Motor score of GCS, age, sex, smoking, hypertension, intraventricular haemorrhage (IVH) and intracerebral haemorrhages (ICH)).Results9 patients (38%) of POG were WFNS grades IV – V versus 1 patient (13%) in GOG. More POG than GOG patients had IVH (83% vs 38%, rs=−0.44 p=0.011). 20% of POG had ICH vs none in GOG. GOG patients had better GCS (rs=−0.37, p=0.04), lower WFNS grade (rs=0.43, p=0.01) and did not need external ventricular drain (EVD) (rs=0.51, p=0.003). There was no significant correlation between outcome and sex, smoking, hypertension, size of aneurysm (4.9 mm ±1.0 in GOG vs 5.4 mm ±1.1 in POG, rs=−0.29, p=0.28), percentage receiving coiling or clipping, GCS motor score, procedure complications and general medical complications.Conclusions75% of patients’ aged ≥80 y with SAH had poor outcome. WFNS grade (I-III), higher GCS patients who did not need EVD had better outcome.
