We meet regularly to critically discuss recent publications about delirium. If you're interested, send an email to our Chief Scientific Officer, Dr. Benjamin Dodsworth,

As of today, no precise tool for patient screening and risk determination is yet available in the current clinical practice.​

Preventive strategies could help reduce POD incidence and thus improve patient’s quality of life.  For instance, finding the high-risk patients preoperatively would allow for the adoption of tailored and protective perioperative measures.
In parallel, it would also be crucial to properly inform patients about their risk of suffering from cognitive impairment after undergoing any surgery, under general anesthesia.

The impact of post-operative delirium on patients is enormous.

Dr. med. Rebecca von Haken from the University Hospital Mannheim and member of the Delir Network, Heidelberg has much experience with patients who end up with POD. What impact has a post-operative delirium in older people? And what are she and her team doing to help patients with a high risk of post-operative delirium?
