What this trial studies

This project aims to develop and implement a national multimodality smartphone application for patients with bladder cancer, building on insights from the iBLAD study. The app will include patient-reported outcome (PRO) questions regarding symptoms and quality of life, as well as information for healthcare providers and peer-to-peer advice. The usability and patient satisfaction with the app will be evaluated using qualitative methods. Patients will receive weekly electronic questionnaires to monitor their symptoms and side effects throughout their treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with bladder cancer undergoing standard therapy who can read Danish.

Not a fit: Patients without a smartphone or those with serious cognitive impairments may not benefit from this study.

Why it matters

Potential benefit: If successful, this app could enhance symptom management and quality of life for bladder cancer patients.

How similar studies have performed: Other studies have shown success with similar digital health interventions, indicating potential for positive outcomes.
