Intraoperative EEG suppression duration has been associated with postoperative delirium and mortality.

In a clinical trial testing anaesthesia titration to avoid EEG suppression, the intervention did not decrease the incidence of postoperative delirium, but was associated with reduced 30-day mortality.

The present study evaluated whether the EEG-guided anaesthesia intervention was also associated with reduced 1-yr mortality.

This manuscript reports 1 yr follow-up of subjects from a single-centre RCT, including a post hoc secondary outcome (1-yr mortality) in addition to pre-specified secondary outcomes.

The trial included subjects aged 60 yr or older undergoing surgery with general anaesthesia between January 2015 and May 2018. Patients were randomised to receive EEG-guided anaesthesia or usual care.

The previously reported primary outcome was postoperative delirium. The outcome of the current study was all-cause 1-yr mortality.
