Brief Summary

Chronic pain affects approximately 20% of adults, 50% of the elderly population and over 1.5 billion people worldwide. Societal and economic issues are also crucial, as 60% of people with pain are less able or unable to work and 20% say they have lost their jobs because of pain. The overall cost of chronic pain is estimated at around 300 billion euros in the EU. Unfortunately, current treatments for chronic pain have limited effectiveness and important adverse effects. Pain clinics, which support the most complex and refractory cases of chronic pain, as well as general practitioners and patients expect improvements, both in terms of therapeutic efficacy and organization of care. In order to allow the characterization and a personalized follow-up of chronic pain patients, we have created e-DOL, a smartphone application for patients and a web platform for healthcare professionals in pain clinics. The purpose of this study is to create an e-cohort for the research, and characterization and follow-up of chronic pain patients.
