This study is a pilot randomized controlled trial, comparing a group of older patients with standardized non‐pharmacological delirium prevention plus a basic tablet versus a group with standardized non‐pharmacological delirium prevention plus a tablet with a software of cognitive stimulation (PREVEDEL). Software:It is a local development, including a interprofessional team of delirium healthcare experts, older patients and a team og engineers. The software was developed during the first year of this project and was inscribed for author rights. Inclusion criteria: Older patients > 65 y.o.

Intervention: All patients will have a tablet with or without the software PREVEDEL between 09:00‐19:00 hrs. Measures: delirium will be monitoring with CAM (Confusion Assessment Method) twice a day for 5 days. Primary outcome: Delirium rate between both groups Secondary outcomes:Long of stay, severity od delirium, time of use of electronic device, and Barthel to discharge.
