Incidence of delirium post cardiac surgery: Discrepancy between clinical observation, DOS scores, and single‑lead EEG

Our findings reveal significant discrepancies in POD detection rates by diagnostic methods. The high sensitivity of sl-EEG suggests a risk of false positives, while clinical assessment and DOS may risk underdiagnosis, especially in hypoactive delirium. An integrated diagnostic approach combining multiple methods may improve accuracy and capture the full spectrum of delirium symptoms. Future studies should refine these tools and explore advanced technologies to develop reliable, easily deployable diagnostics for clinical practice.
