Authors analyzed whether perceptions of discrimination in health care changed in California over the last decade. The cross-sectional study of a racially, ethnically, and linguistically diverse adult population used data from pooled 2003 to 2005 and pooled 2015 to 2017 California Health Interview Survey (CHIS) data.

Findings:

• Perceptions of discrimination in health care decreased significantly overall from 6% to 4%.
• In subanalyses, this finding was significant among Latino respondents, immigrants, and those with limited English proficiency.
• However, perceptions of discrimination in health care among African American individuals have not improved and remain relatively high.

This study suggests that perceptions of discrimination in health care have improved for some populations, but interventions to reduce discrimination in health care are still necessary.
