DENIM-trial: Digital prE-operative patieNt guIdance systeM

The mobile application provides patients with tailored information during the preoperative period until seven days after surgery. 1) Before the preoperative outpatient clinic visits, patient will receive information regarding the preoperative screening process and an overview of available anesthesia techniques through videos embedded in the app. 2) After approval for surgery and during the period leading up to the day of surgery, they will receive instructions concerning medication adjustment, lifestyle modifications, fasting rules, and hygiene measures.

Patients in the control group will be asked to download the same mobile app but they will not receive the same tailored information as those in the intervention group. Instead, they will be provided with standard preoperative information and instructions. In addition, they will be asked to fill out the same questionnaire as the intervention group.
