Electroencephalographic Monitoring in the Recovery Room for Identification of Patients at Risk for Postoperative Delirium
Main finding · Recovery-room EEG power and POD discriminationResult — go to the resultAUC 0.69 95% CI 0.60–0.77Authors' conclusion
These data suggest that frontal EEG monitoring in the recovery room can help identify a "vulnerable brain" phenotype associated with increased POD risk.
Study context
- Population
- Older adults undergoing surgery, Charité-Universitätsmedizin Berlin, 2019 to 2022sufficient EEG data for analysis
- Participants
- 184 adults
- Exposure
- Recovery-room frontal EEG features in patients with vs without postoperative delirium (POD)
- Outcome
- Frontal EEG signatures (spectral-domain features, monitor-derived indices) in the recovery room and POD (screened in recovery room and twice daily for 5 days)

As reported in the abstract
Observational data: associations, not effects.
Further findings
EEG power change vs preoperative baseline
- No POD: increased alpha- and beta-band power (8 to 20 Hz) vs baseline, highest at ≈16 Hz
- POD: spectral patterns comparable to baseline across all frequency bands
