In 2014, the Delirium Risk Profile (DRP), a self-administered computer program for tablet computers, was developed at the University Hospital Basel to assist preoperative screening. It was tested in healthy and cognitively impaired volunteers, as well as in patients undergoing surgery. The aim of this study is to provide normative data for the computer program DRP, and to enable clinicians to administer the DRP as a routinely used tool in the Preoperative Evaluation Clinic.
