Study: NCT06352710

Intervention type: OTHER
Intervention: OP-Tracker App
Description: There will be no study-specific therapeutic intervention. The OP-Tracker App will be downloaded and installed on the patient's smartphone. Preoperative assessment: baseline factors such as age, gender, medical conditions, type of disease and of surgery, EQ-5D-5L. Before and after surgery surgery, SWI (Quality of life) will be assessed daily using pop-ups; the patient will input the value (0-10) using a slide-bar. After completion of the surgery, the app will automatically modify the number of SWI assessments over time according to the occurrence of AEs. At any point in time, the patient will be able to register an AE in the smartphone app. The patient can select the AE via a drop-down menu in the app, and can additionally input free text in case of an AE of type other. Using a further drop-down menu, the patient will classify the AE according to the CDG and TDN grade. QoL assessments (EQ-5D-5L questionnaire) will pop up before, and at 3 and 12 months after surgery.
