Indicator: Emergency department visits, 0-17 years due to asthma per 10,000
Description: The number of ED visits with asthma as the primary diagnosis, among children age 0-17 in California, expressed as a rate per 10,000 residents. Asthma is highly prevalent among California children. ED visits for asthma can often be avoided with proper asthma management. ED visits are costly to the medical system. Data are obtained from the California Office of Statewide Health Planning and Development (OSHPD). All non-federal hospitals in California are required to submit ED data to OSHPD on a quarterly basis. These records are estimated to include 98% of all ED visits in California. Limitations include: race/ethnicity data have not been validated; records are visit-based and not person-based; there is a potential for incorrect diagnoses and inconsistent coding.
Data Limitations: The California data are based on the universe of records from all licensed hospitals, as submitted to OSHPD.
Indicator Source: Office of Statewide Health Planning and Development (OSHPD)
Indicator Calculation Methodology: (Number of Asthma-related ED visits / Total county or state population) x 10,000
Data Source: The OSHPD ED Database. Notes: Numerator for rates is ED visits with a principal diagnosis using ICD-9 code 493 or ICD-10 codes beginning with J45 (after October 2015). Counts are based on the number of visits, not the number of unique individuals. Denominator for rates is the estimated number of residents based on CA Department of Finance estimates.
