Health at a Glance 2021
OECD Indicators
Health at a Glance provides a comprehensive set of indicators on population health and health system performance across OECD members and key emerging economies. These cover health status, risk factors for health, access to and quality of health care, and health resources. Analysis draws from the latest comparable official national statistics and other sources.
Alongside indicator-by-indicator analysis, an overview chapter summarises the comparative performance of countries and major trends. This edition also has a special focus on the health impact of COVID-19 in OECD countries, including deaths and illness caused by the virus, adverse effects on access and quality of care, and the growing burden of mental ill-health.

Diagnostic technologies
Technologies play an important role in medical diagnoses: from physical examination and results processing and sharing, to accessing patients’ health records, to the review of clinical histories. However, new technologies can also drive up costs, and are commonly acknowledged to be one of the main causes of increases in health spending (Lorenzoni et al., 2019[20]). This section presents data on the availability and use of three diagnostic imaging technologies: computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET). CT and MRI examinations (exams) both show images of internal organs and tissues, while PET scans show other information and problems at the cellular level.
