Asthma ED Visit Rates (LGHC Indicator)

This is a source dataset for a Let's Get Healthy California indicator at letsgethealthy.ca.gov/. This dataset contains counts and rates (per 10,000 residents) of asthma (ICD9-CM, 493.0-493.9) emergency department visits among California residents by County and age group (all ages, 0-17, 18+). The data are derived from the Department of Health Care Access and Information emergency department databases.

These data include emergency department visits from all licensed hospitals in California. These data are based only on primary discharge diagnosis codes (ICD9-CM). Starting in 2019, HCAI classified non-Hispanic individuals who identified with two or more races as "Multiracial." Previously these were assigned to a single other race.
