California emergency departments (EDs) treated about 143,000 people experiencing homelessness in 2019, according to hospital discharge records. Almost half of homeless patients visited the ED four or more times in the year.
Medi-Cal covered 70 percent of ED visits by homeless patients, underscoring the importance of the CalAIM program, which provides added Medi-Cal benefits, such as housing supports and case management.
Linking discharge data with homeless assistance program data can offer insights into how people engage with EDs and homeless services across the state, and throughout the year, as well as help evaluate programs and public investments.
