Doctors and nurses subjective predictions of 6-month outcome compared to actual 6-month outcome for adult patients with spontaneous intracerebral haemorrhage (ICH) in neurocritical care: An observational study

•Doctors and nurses are realistic about the likelihood of a poor outcome but tend to err on the side of optimism for prognosticating ICH mortality suggesting an absence of clinical nihilism.•Realistic optimism may underpin early prognostication in neurocritical care.•No sub-group were more accurate than any other when predicting outcome.•Prognostication is subjective and variable in the first 48 h of ICH admission to neurocritical care highlighting a need for a standardised approach.
