KFF Health News is a national newsroom that produces in-depth journalism about health issues and is one of the organization’s core operating programs.
The Peterson-KFF Health System Tracker is an online hub monitoring how well the U.S. health system is operating through key quality and cost measures. Visit the Tracker →
This chart collection compares health care spending in the U.S. and other industrialized countries, including data on health spending per person and the growth rate in recent years and over time.
This slideshow compares mortality rates in the United States and other industrialized countries for seven major causes of death. The data show that U.S. mortality rates for circulatory diseases and cancer have fallen in the past 30 years, driving a decline in the nation's overall rate. However, mortality rates for leading causes of death other than cancer are higher in the United States than the average for comparable countries.
This slideshow examines how cost and insurance affects people's access to care, including decisions to forgo or delay needed care and access to a usual source of care.
This slideshow looks at how much the United States spends to treat specific diseases and tracks spending growth over time, using data from the Bureau of Economic Analysis Health Care Satellite Account. The analysis shows that three disease categories -- ill-defined, musculoskeletal and circulatory conditions -- account for about a third of medical services spending growth in the United States from 2000 to 2010. Spending on ill-defined conditions -- including check-ups, preventive care and treatment of colds and other minor conditions -- grew the fastest during that time period.
This slideshow charts the recent slowdown in health spending in the United States and other industrialized nations. Some possible causes include economic factors and structural changes to the U.S. health system, such as higher cost sharing in private health insurance and lower payments to providers by Medicare and other public programs.
The Kaiser Family Foundation, in partnership with the Peterson Center on Healthcare, today announced a new online hub dedicated to monitoring and assessing the performance of the U.S. health system.

In general, people in the United States use the health system less than people in comparable countries, and services in the U.S. are consistently more expensive than in countries of similar size and wealth. This slideshow examines price and utilization of several healthcare services, including magnetic resonance imaging, caesarian sections, angioplasty surgery and coronary bypass surgery, through data from the International Federation of Health Plans and the Organisation for Economic Co-operation and Development.
This updated chart collection compares indicators of health care utilization and prices in the United States and 11 similarly wealthy countries to investigate whether higher prices or higher utilization of health care services drives the high health care expenditures in the U.S. relative to peer nations.
This chart collection examines five types of indicators: outcomes of treatment, provision of appropriate treatment, patient safety, preventive services, and health system capacity and workforce shortages. Measuring quality in health care is complex: a vast number of metrics are used to monitor health system performance since there is no singular definition of quality, and data is often limited and delayed.
