Patient Characteristics by County and Facility

In 2023, 79% of all patients seen in a general acute care hospital setting in California were treated in the Emergency Department (ED) and 14% of the patients seen in the ED were admitted to the inpatient setting.

Introduction

The 2023 Patient Characteristics by County and Facility visualization presents a calendar year overview of patients’ demographic and other characteristics in general acute care hospital settings in California.

Both a single-year view (2023) and a multi-year perspective (2017-2023) are available, with view at the statewide level, by county or counties, or compare up to two facilities. The data can be filtered by encounter setting: Ambulatory Surgery (AS), Emergency Department (ED), Inpatient not admitted from the ED (Inpatient not from ED) and Inpatient admitted from the ED (Inpatient from ED). 

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

Key Findings

  • 79% of all patients being seen in general acute care hospital settings in California were treated in the ED and 14% of the patients seen in the ED were admitted to the inpatient setting.

  • Patients age 65 and over comprise 49% of patients who are admitted to the hospital as the result of an ED visit, but only 19% of patients who visit the ED without being admitted.

How HCAI Created This Product

The Patient Characteristics by County and Facility report was created using California’s Inpatient, Emergency Department and Ambulatory Surgery data for the years 2017 – 2023. 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). This product masks small numbers by including any counts under 11 in the “Other/Unknown” category. This is done to protect patients’ health information while providing maximum amount of allowable information to the user. The “Other/Unknown” category also contains invalid and missing values.

Race/Ethnicity: The “Other/Unknown” category includes Other Race, Unknown, invalid, missing values and cells where the values were less than 10. Individuals whose ethnicity is Hispanic or Latino were assigned to the “Hispanic” category regardless of race. Individuals identified as Native Hawaiian or Other Pacific Islander were assigned to the “Asian” category. Individuals whose ethnicity is not Hispanic or Latino and who were associated with more than one race were assigned to the “Non-Hispanic Multiracial” category.
