Summary

This trial tests whether a smartphone app called e-DOL can help doctors and patients track chronic pain over time. The app lets patients record pain levels, anxiety, and sleep quality, while doctors view the data on a web platform. The study includes adults with chronic pain who own a smartphone and aims to see if the tool is easy to use and practical for everyday care.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: e-DOL, a smartphone application for patients and a web platform for physicians
What this could lead to: If the app proves practical and useful, it could offer a new way to personalize chronic pain care and improve communication between patients and doctors.
What could go wrong: This is a feasibility study, so it focuses on whether the tool is usable rather than on health outcomes. The app may not be accepted by all patients or may not improve pain management in the long run.
