Helena Claesson Lingehall

Helena Claesson Lingehall is an Affiliated Researcher at Örebro University's School of Health Sciences and Department of Health Sciences, with additional affiliation at Umeå University. Employed by Region Örebro County, she works at the Vascular and Thoracic Clinic at Örebro University Hospital (USÖ) with a 100% position that includes 20% educational responsibilities for staff training in vascular-thoracic surgery and student supervision.

Dr. Claesson Lingehall is a specialist nurse in anesthesia and intensive care who completed her doctoral thesis at Umeå University in 2016 titled 'Delirium in older people after cardiac surgery: risk factors, dementia, patients' experiences and assessments.' Her research primarily focuses on postoperative complications in cardiac surgery patients, with special emphasis on acute confusional states (delirium) among elderly patients. She investigates risk factors for postoperative delirium (POD), including both patient-related and treatment-related factors.

Her publication record shows a clear progression from validation of assessment tools to investigating specific physiological mechanisms. Recent publications (2023-2025) focus on cardiopulmonary bypass parameters and their relationship to postoperative complications like delirium and acute kidney injury. Her work appears in high-impact journals across anesthesiology, cardiac surgery, and nursing, demonstrating an interdisciplinary approach that bridges clinical practice with physiological monitoring and patient experience.

Dr. Claesson Lingehall leads two systematic quality projects at Örebro University Hospital targeting acute confusional states and perioperative hypothermia. She collaborates with researchers at Umeå University and Karolinska Institutet (PeriBrainCare project) on studies examining postoperative neurocognitive recovery. Her additional research areas include postoperative nausea and vomiting (PONV) in cardiac surgery and perioperative hypothermia in vascular surgery, with specific focus on risk factors and patient outcomes.
