Chronic pain affects a significant portion of adults and elderly individuals worldwide and presents major societal and economic challenges, including reduced work ability and high healthcare costs. Current treatments often have limited success and notable side effects, leading to a need for better therapeutic options and care organization. This research aims to create a French e-cohort to enable personalized monitoring and detailed characterization of chronic pain patients using innovative digital tools. Participants will use the eDOL system, a digital health tool that includes a smartphone app for patients and a web platform for healthcare providers in pain clinics. This system collects a wide range of data through repeatable questionnaires, weekly symptom tracking, therapeutic education, and a conversational agent. The study will enroll a minimum of 5000 patients from 20 pain clinics and follow them for 24 months to gather comprehensive real-life information. Throughout the study, data on pain, related conditions, sleep, activity, emotional factors, demographics, and treatments will be collected and linked to French health insurance records to assess care usage and comorbidities. Researchers will analyze these data over five years to better understand chronic pain and its impacts. Participants will regularly complete assessments via the eDOL app, enabling ongoing monitoring and personalized follow-up in real-world settings.
