Summary
Brief summary
The purpose of this international, multi-centre observational study is to describe perioperative cognitive changes (pre-existing neurocognitive disorder \[NCD\], postoperative delirium \[POD\] and Postoperative Cognitive Dysfunction \[POCD\]) up to five years after elective surgery in a mixed cohort. Measurements and definitions of cognitive outcomes will be based on current consensus and used for further harmonization in future clinical studies on perioperative cognitive trajectories. This is a feasibility approach to identify an effective screening procedure and estimate loss to follow up rates for the planning of future intervention studies. Data from this trial may also serve to facilitate and implement time effective cognitive screening and risk stratification concerning postoperative cognitive decline in the anaesthesiological preoperative assessment.
