Outcomes after inter‐hospital transfer of intensive care patients with haemorrhagic stroke: a 5‐year retrospective review

Abstract

AbstractBackgroundInter‐hospital transfer (IHT) of intensive care patients is a limited resource. We assessed the outcomes of patients with haemorrhagic stroke requiring IHT and intensive care and aimed to identify early prognostic factors of poor neurological outcome.MethodsWe conducted a retrospective observational cohort study of patients admitted to a single tertiary intensive care unit (ICU) with haemorrhagic stroke after IHT between January 2014 and December 2018. Primary outcome was poor neurological outcome (modified Rankin Scale ≥4 at time of discharge from hospital or rehabilitation unit). Secondary outcomes were mortality rate, rate of intervention, rate of organ donation surgery (ODS) and potentially avoidable transfer (PAT). PAT was defined as transfer where the patient did not receive an intervention and had a poor neurological outcome.ResultsNinety patients were included in this study, 48 with intracerebral haemorrhage (ICH) and 42 with subarachnoid haemorrhage (SAH). Fifty‐one (56.7%) patients had a poor neurological outcome, including 30 (33%) who died. Factors significantly associated with poor neurological outcome included age > 80 years, lower presenting Glasgow Coma Score (GCS) and bilaterally fixed and dilated pupils. Stepwise logistic regression demonstrated history of hypertension as significantly associated with poor neurological outcome in patients with ICH (P = 0.021). Seven (7.8%) patients had ODS. Sixty‐four (71.1%) patients received intervention and 20 (22.2%) transfers were potentially avoidable.ConclusionsPatients in this cohort are at high risk of poor neurological outcome. Prognostic factors identified in this study may help referring, retrieval and receiving clinicians to discuss futility prior to pursuing IHT.
