Brief Summary:
Postoperative delirium (POD) - a temporary state of confusion - is a frequent complication of surgery, which most commonly occurs in elderly patients. A tablet computer application that may assist preoperative risk screening for POD was developed at the University Hospital Basel in 2014. This study aims to investigate whether the computer program may assess the risk of a patient to develop POD.

Preoperatively, all study participants (entire cohort) will perform in the self-administered tablet computer-based tool to assess the risk of developing POD.

Primary Outcome Measures :
  1. Incidence of POD. [ Time Frame: Day 1-5 after surgery. ]
    Incidence of POD, detected by the DRS-R-98.

Secondary Outcome Measures :
  1. Severity of POD. [ Time Frame: Day 1-5 after surgery. ]
    Severity of POD, measured by the DRS-R-98.
