[E-health, digitalization, or digital transformation: Impact on cancer supportive care].

The value of comprehensive oncology management including supportive care is well established, but it remains challenged by the increasing need and access disparities. By enabling real-time, dynamic, technology-assisted assessments and interventions, e-health is a key for optimizing supportive care in Oncology in 2021. Indeed, e-health has the potential to improve communication between the patient and the healthcare professional, improve the assessment and management of symptoms and toxicities, and optimize patient engagement across the continuum of care. We are witnessing a new era of patient-centered care, where the patient becomes an actor in his or her own care. In this review, we present the definitions and the French legal framework of e-health, and some currently available e-health solutions in oncology focused on supportive care, including the issues of their validation and financing. We will also discuss the challenges and access for patients, as well as the issues of access, security and transfer of health data.
