Providing safe, effective, responsive and patient-centred care, that is also cost-effective and accessible, requires that those making decisions – from patients to health care providers, managers and scientists – have timely and accurate health data and information (OECD, 2019[12]). When health data and information are understandable and valid for a range of uses and users, new digital health services and applications become possible. From telehealth to artificial intelligence, new digital health services may lead to better access to health care and higher patient satisfaction, especially among those patients that face the most barriers to traditional face‑to-face care services (e.g. rural patients). A digital transformation of health care is taking place across OECD countries, accelerated by the COVID‑19 pandemic and driven by a digitalisation of information infrastructure, as well as growing demand from patients.
