Validated screening tools should be routinely used to recognise this psychopathological syndrome. Delirium might be associated with systematic changes in brain network organisation, including reduced EEG connectivity. Methods: This observational single-centre pilot study aimed to evaluate the agreement between DeltaScan\u00ae (Prolira BV, Utrecht, The Netherlands) and CAM-ICU screening in detecting postoperative delirium in patients undergoing cardiac surgery or cardiac intervention. Results: 1. Patients showing delirium have DeltaScan\u00ae scores \u2265 3. 2. Patients scoring \u2265 3 in the DeltaScan\u00ae examination do not necessarily show signs of delirium in CAM-ICU testing. 3. All patients showing delirium in CAM-ICU testing have pathological clock-drawing results. Conclusions: DeltaScan\u00ae reliably detects delta wave abnormalities associated with delirium, though some patients with increased delta activity did not exhibit clinically manifest delirium.<\/jats:p>","DOI":"10.3390\/life15101640","type":"journal-article","created":{"date-parts":[[2025,10,21]],"date-time":"2025-10-21T14:17:35Z","timestamp":1761056255000},"page":"1640","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Comparison of DeltaScan\u00ae and CAM-ICU for the Assessment of Postoperative Delirium in Patients Undergoing Cardiac Surgery and Cardiac Interventions: A Prospective Observational Pilot Study"],"prefix":"10.3390","volume":"15","author":[{"given":"Astrid","family":"Bergmann","sequence":"first","affiliation":[{"name":"Department of Anaesthesiology, Heart- and Diabetes-Center Bad Oeynhausen, Ruhr-University Bochum, 44801 Bochum, Germany"},{"name":"Department of Anaesthesiology, Heart- and Diabetes-Center Bad Oeynhausen, Medical Center East Westphalia-Lippe, University Bielefeld, 33615 Bielefeld, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janis","family":"Fliegenschmidt","sequence":"additional","affiliation":[{"name":"Department of Anaesthesiology, Heart- and Diabetes-Center Bad Oeynhausen, Ruhr-University Bochum, 44801 Bochum, Germany"},{"name":"Department of Anaesthesiology, Heart- and Diabetes-Center Bad Oeynhausen, Medical Center East Westphalia-Lippe, University Bielefeld, 33615 Bielefeld, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silvia","family":"Ruggeri","sequence":"additional","affiliation":[{"name":"Department of Anaesthesiology, Heart- and Diabetes-Center Bad Oeynhausen, Ruhr-University Bochum, 44801 Bochum, Germany"},{"name":"Department of Anaesthesiology, Heart- and Diabetes-Center Bad Oeynhausen, Medical Center East Westphalia-Lippe, University Bielefeld, 33615 Bielefeld, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikolai","family":"Hulde","sequence":"additional","affiliation":[{"name":"Department of Anaesthesiology, Heart- and Diabetes-Center Bad Oeynhausen, Ruhr-University Bochum, 44801 Bochum, Germany"},{"name":"Department of Anaesthesiology, Heart- and Diabetes-Center Bad Oeynhausen, Medical Center East Westphalia-Lippe, University Bielefeld, 33615 Bielefeld, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catharina","family":"Middeke","sequence":"additional","affiliation":[{"name":"Department of Anaesthesiology, Heart- and Diabetes-Center Bad Oeynhausen, Ruhr-University Bochum, 44801 Bochum, Germany"},{"name":"Department of Anaesthesiology, Heart- and Diabetes-Center Bad Oeynhausen, Medical Center East Westphalia-Lippe, University Bielefeld, 33615 Bielefeld, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudia","family":"Bunge","sequence":"additional","affiliation":[{"name":"Department of Anaesthesiology, Heart- and Diabetes-Center Bad Oeynhausen, Ruhr-University Bochum, 44801 Bochum, Germany"},{"name":"Department of Anaesthesiology, Heart- and Diabetes-Center Bad Oeynhausen, Medical Center East Westphalia-Lippe, University Bielefeld, 33615 Bielefeld, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7333-2418","authenticated-orcid":false,"given":"Maria","family":"Preising","sequence":"additional","affiliation":[{"name":"Clinic of Anaesthesiology, University-Hospital G\u00f6ttingen, 37075 G\u00f6ttingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0889-1381","authenticated-orcid":false,"given":"Carsten","family":"Hermes","sequence":"additional","affiliation":[{"name":"Department of Nursing and Management, Hamburg University of Applied Sciences (HAW Hamburg), 20999 Hamburg, Germany"},{"name":"Department of Advanced Clinical Nursing, Akkon University of Human Sciences, 12099 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7281-2137","authenticated-orcid":false,"given":"Vera","family":"von Dossow","sequence":"additional","affiliation":[{"name":"Department of Anaesthesiology, Heart- and Diabetes-Center Bad Oeynhausen, Ruhr-University Bochum, 44801 Bochum, Germany"},{"name":"Department of Anaesthesiology, Heart- and Diabetes-Center Bad Oeynhausen, Medical Center East Westphalia-Lippe, University Bielefeld, 33615 Bielefeld, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"90","DOI":"10.1038\/s41572-020-00223-4","article-title":"Delirium","volume":"6","author":"Wilson","year":"2020","journal-title":"Nat.
