Over the last few decades, there has been significant growth in the measurement and reporting of health care quality outcomes. As health care evolves, it is important to continue to monitor and report on the quality of care delivered to patients in California and across the US. This is part of a series of measures CHCF is publishing on the quality of care in our state. Topics range from maternal to end-of-life care, and include measures on behavioral health, chronic conditions, and providers.

This set of quality measures highlights California’s performance across a range of chronic conditions, including cancer, diabetes, cardiovascular disease, and respiratory disease, and includes data by race/ethnicity, payer, and county.

Many Californians suffer from chronic conditions.

Chronic conditions such as diabetes and heart disease were the leading cause of death and disability in the United States. In 2018, high blood pressure was the most common chronic condition, affecting 3 in 10 adults in California.


The prevalence of obesity among adults varies by race/ethnicity and by payer.

In 2018, over 1 in 4 adults in California was obese. About 4 in 10 Black adults in California was obese. One in 3 adults with Medi-Cal coverage was obese, the highest rate of any payer group.


Black Californians have higher mortality rates for four leading cancers compared with other races/ethnicities.

Black Californians had higher mortality rates for breast, prostate, lung, and colorectal cancer than Asian, Latino, and white Californians in 2017. The largest disparity was with prostate cancer, where Black men had mortality rates that were two times higher than the rate for Latino and white men and four times higher than the rate for Asian men.


Preventable chronic care hospitalizations vary by county.

In California, nearly 700 hospitalizations per 100,000 people were potentially preventable through effective chronic care management and access to high-quality primary care, based on a composite measure of hospital admission rates for eight chronic care conditions. The preventable hospitalization rate varied from a low of 129 in Mono County to a high of 1,341 in Butte County.
