This report examines how countries perform in their ability to prevent, manage and treat cardiovascular disease (CVD) and diabetes.

Health at a Glance provides a comprehensive set of indicators on population health and health system performance across OECD members and key emerging economies. This edition 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.

Health at a Glance compares key indicators for population health and health system performance across OECD members, candidate and partner countries. It highlights how countries differ in terms of the health status and health-seeking behaviour of their citizens; access to and quality of health care; and the resources available for health. Analysis is based on the latest comparable data across 80 indicators, with data coming from official national statistics, unless otherwise stated.

This publication examines current efforts to improve health care efficiency, including tools that show promise in helping health systems provide the best care for their money.

This report examines primary health care across OECD countries before the COVID-19 pandemic, and draws attention to how primary health care is not living up to its full potential. Doing things differently – through new models of organising services, better co-ordination among providers, better use of digital technology, and better use of resources and incentives – helps to improve care, reduce the need for hospitalisations, and mitigate health inequalities.

A growing body of evidence from economic studies shows areas where appropriate policies can generate health and other benefits at an affordable cost, sometimes reducing health expenditure and helping to redress health inequalities at the same time.

During the last 25 years, life expectancy at age 50 in the United States has been rising, but at a slower pace than in many other high-income countries, such as Japan and Australia. This difference is particularly notable given that the United States spends more on health care than any other nation. Concerned about this divergence, the National Institute on Aging asked the National Research Council to examine evidence on its possible causes. According to Explaining Divergent Levels of Longevity in High-Income Countries, the nation's history of heavy smoking is a major reason why lifespans in the United States fall short of those in many other high-income nations. Evidence suggests that current obesity levels play a substantial part as well. The book reports that lack of universal access to health care in the U.S. also has increased mortality and reduced life expectancy, though this is a less significant factor for those over age 65 because of Medicare access. For the main causes of death at older ages-cancer and cardiovascular disease-available indicators do not suggest that the U.S. health care system is failing to prevent deaths that would be averted elsewhere. In fact, cancer detection and survival appear to be better in the U.S. than in most other high-income nations, and survival rates following a heart attack also are favorable. Explaining Divergent Levels of Longevity in High-Income Countries identifies many gaps in research. For instance, while lung cancer deaths are a reliable marker of the damage from smoking, no clear-cut marker exists for obesity, physical inactivity, social integration, or other risks considered in this book. Moreover, evaluation of these risk factors is based on observational studies, which-unlike randomized controlled trials-are subject to many biases.
