Summary: This set of quality measures, which is part of a series of measures California Health Care Foundation (CHCF) publishes on the quality of care in California, focuses on a range of chronic conditions among adults, including diabetes, cancer, cardiovascular disease, and respiratory disease, and includes data by race/ethnicity, payer, and county.

Findings: Obesity or high blood pressure were the most common chronic conditions, affecting more than 1 in 4 adults. Prevalence of chronic conditions in 2021 varied widely by race and ethnicity.

A composite measure of hospital admission rates between 2017 and 2019 for eight chronic conditions showed nearly 700 hospitalizations per 100,000 people were potentially preventable through effective chronic care management and access to high-quality primary care. The preventable chronic condition hospitalization rate varied by race and ethnicity, ranging from a high of 1,719 for Black adults to a low of 361 for Asian, Native Hawaiian, and Pacific Islander adults.

Alaska Native and American Indian and Black Californians had higher mortality rates for breast, prostate, lung, and colorectal cancer than other races and ethnicities. The largest disparities were with prostate and lung cancer: The prostate cancer mortality rate for Alaska Native and American Indian and Black men was two times higher than the overall rate in California, and the lung cancer mortality rate for Alaska Native and American Indian Californians was well over two times higher than the state’s overall rate.

The report includes 2021 California Health Interview Survey (CHIS) data for obesity and heart disease (both by race and ethnicity), and for all chronic conditions (asthma, diabetes heart disease, high blood pressure, obesity). Other data were from RaceCounts and California Cancer Registry.
