Hospital and Workforce Behavioral Health Data in California
To better understand and respond to the growing behavioral health needs impacting healthcare services throughout California, HCAI offers a range of topical data products focused on behavioral health. These resources include key findings and trends that help inform strategies, improve program effectiveness, and promote health equity for all Californians.
Defining Behavioral Health
Behavioral health is an umbrella term that covers mental health (e.g., depression, anxiety disorders, schizophrenia and other psychoses) and substance use disorders. It includes our emotional, psychological, and social well-being. It helps determine how we handle stress, relate to others, and make healthy choices. Behavioral health is important at every stage of life, from childhood and adolescence through adulthood.

The Behavioral Health Hospitalization Landscape
The National Institute of Mental Health reported that nearly one-in-five adult Americans live with a mental illness. In California, that equates to nearly eight million people. HCAI’s behavioral health data indicates potential strains on the California healthcare system, as the prevalence of behavioral health diagnoses has risen in recent years. Inpatient (IP) stays and emergency department (ED) visits often become the default response when individuals face acute behavioral health crises due to gaps in community-based care, prevention programs, and outpatient services.
In 2020 and 2021, more than one-third of all IP hospitalizations and one-fifth of all ED visits were linked to a behavioral health diagnosis. This amounts to approximately three million behavioral health-related hospitalizations each year, which translates to about six hospitalizations every minute:
- 3,359,970 hospitalizations per year
- 279,998 hospitalizations per month
- 9,192 hospitalizations per day
- 383 hospitalizations per hour
- 6.38 hospitalizations per minute
Based on the time you’ve spent on this page, the timer below displays the average count of hospitalizations with a behavioral health diagnosis as time progresses.
The continuum of care in behavioral health extends far beyond ED visits and IP hospitalizations. After initial stabilization in the ED or IP setting, patients often transition to outpatient services such as therapy, medication management, and case management to continue their recovery in a less intensive environment. Additionally, community resources like housing support, peer counseling, and substance use programs play a critical role in long-term recovery by offering support and resources as patients reintegrate into their communities. Follow-up care ensures that patients maintain their progress and avoid relapse, often through regular check-ins and preventive programs.
