Health care organisations globally are developing and implementing digital health services in a systemic shift towards medical technologies and digital care. Digital health has been defined as any application of information and communication technologies to improve healthcare and health outcomes, and the current emergence of medical technologies moves rapidly and broadly across clinical specialties. The concept and application of ethics and person-centredness in such digital medical technology is surprisingly absent from scholarly and clinical debate. For example, Martin Buber suggests relational ethics in terms of I-it relationships or I-thou relationships. Firstly, I-it relationships refers to objectifying, distant and instrumental ways of relating to others, and indicates partial, pragmatic or partial interactions where “it” remains the object for I. Secondly, I-thou denotes a more person-centred and relational ethics where oneself and the other have encounters that are mutual, reciprocal, equivalent and dialogical where the I engage personally with the thou. Such relational ethics also emerges in the GPCC theoretical framework where the patient’s story, forming a partnership and using narratives for documentation are key.  I-thou relationships can develop when we conceptualize, describe and act towards others in terms of who they are rather than what they are, when encounters are close and personal instead of distant and professional. As medical technology and digital health services influence relationships in particular ways, there is a need to further analyse, highlight and critically discuss the ethics and person-centredness in such applications, particularly for older adults. This paper will contribute with such a critical analysis of relational ethics and person-centredness in the context of medical technologies and digital health.
