In 2022, 79 percent of all patients being seen in general acute care hospital settings in California were treated in the Emergency Department (ED) and 14 percent of the patients seen in the ED were admitted to inpatient care.

Why publish Patient Characteristics by County and Facility, 2022?

The 2022 Patient Characteristics by County and Facility Data Visualization presents a calendar year overview of patients in general acute care hospital settings in California.

The data can viewed statewide, by county or counties, and by selecting up to two facilities for comparison. The data can be filtered by setting type: Ambulatory Surgery Only (AS Only), Emergency Department Only (ED Only), Inpatient Only and Inpatient from Emergency Department (Inpatient from ED).

Other reported data categories include Race/Ethnicity, Assigned Sex at Birth, Age Group and Expected Payer.

How HCAI Created This Product

To protect patient personal information, the California Health and Human Services Agency has adopted a policy of statistically masking or de-identifying sensitive data (CalHHS Data De-identification guidelines). Data from any group with less than 11 individuals are labeled and numerator groups with less than 100 were also labeled. In addition, groups are rounded to the tens place value. All percentages reflect these changes, not the original number of encounters.

Medicare includes: Medicare Advantage, traditional Medicare. Medi-Cal includes: Medi-Cal managed care, fee-for-service Medi-Cal. Private Coverage includes: employer group coverage, individual coverage (including coverage purchased through Covered California), organized charity payers (e.g., March of Dimes, Shriners). Uninsured includes: uninsured patients, as well as instances when insurance does not cover the treatment, or the patient would like to keep the medical procedure private.

*Other Payer includes: Workers’ Compensation, County Indigent Programs, any third-party payment not included in any other category, stays for which no payment will be required by the facility (e.g. courtesy patients), and stays for which no valid expected payer was reported to HCAI.
