California’s emergency departments (EDs) provide a critical source of health care to people with acute medical conditions and those who have experienced trauma or injury. EDs are expected to treat all patients regardless of their ability to pay. They also provide an important entry point for inpatient hospital care. In 2021, 325 acute care hospitals in California operated a licensed ED. Between 2011 and 2021, the number of EDs remained relatively stable, while the number of individual treatment stations increased 21% from 7,168 to 8,667. In 2021 California’s EDs handled 12.9 million visits, 7% more than in 2011.
California’s Emergency Departments: A Critical Source of Care looks at the most recent data on supply, visits, and wait times, as well as trends from 2011 to 2021.

- In 2021, emergency department visits per 1,000 residents ranged from a low of 267 in Orange County to a high of 420 in the Northern and Sierra region.
- Medi-Cal was the expected payer for 41% of all ED visits in 2021, compared to 27% for private payers and 23% for Medicare.
- Of the 85% of ED visits that did not result in a hospital admission, one in five were for conditions severe enough to be life-threatening.
