France's initiative to create a centralized online medical file for all citizens, known as the Personal Medical File (DMP), was launched in 2004 with the goal of improving healthcare efficiency. The system was intended to collect medical histories, prescriptions, and test results in one place, which was expected to save 3.5 billion euros annually by reducing redundant medical tests and improving coordination of care. However, despite over 20 years of effort, the program has seen limited success. According to the Court of Audit, more than nine out of ten of the approximately 40 million digital medical records created have never been filled in by healthcare professionals. The project faced early challenges, consuming at least 210 million euros to create only 158,000 open records, half of which were empty. In 2012, the program was suspended due to widespread underuse. Key reasons for the failure include a lack of shared goals between patients and doctors, time constraints on healthcare providers, and public distrust in centralizing medical data. A relaunch in 2017 under the name My Health Space aimed to improve the system, but the core issue—low adoption by doctors—has not been resolved. Evaluations by health institutions point to a lack of clear leadership in managing the development of digital health data and a perception among healthcare professionals that the tool is not practical for their busy schedules. In nine pilot regions, the relaunched program showed some promise, with up to 10,000 new records created each week. However, convincing doctors to consistently use the system remains a major hurdle. To address these issues, the government has worked to simplify the My Health Space interface and highlight its benefits for both patients and healthcare providers. Yet, for the system to succeed, it must rebuild public trust and ensure real adoption by medical professionals. The gap between the original 2004 vision of a fully utilized digital health record for every citizen and the current reality of low usage underscores the need for more user-centered design in digital health initiatives.
