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.
This analysis compares 2021 data about deaths in the U.S. and 11 other large, wealthy countries by age and cause to understand the primary drivers of the longevity gap between the U.S. and the comparable countries. It finds that the primary reasons for the gap in 2021 were chronic disease, COVID-19 and substance use disorders.
This chart collection examines how life expectancy in the U.S. compares to that of other similarly large and wealthy countries. Between 2019 and 2022, the U.S. experienced a sharper decline and a slower rebound in life expectancy than peer countries, on average, due to increased mortality and premature death rates in the U.S. from the COVID-19 pandemic. In 2023, life expectancy in the U.S. returned to pre-pandemic levels, but remains lower than that of comparable countries.
