FIGURE 2.

The figure is a line chart showing weekly seizure- or epilepsy-related emergency department visits among persons aged ≥40 years, by age group, using data from the National Syndromic Surveillance Program, in the United States, during 2019–2021.

Weekly seizure- or epilepsy-related emergency department visits among persons aged ≥40 years, by age group* — National Syndromic Surveillance Program,† United States, 2019–2021

Abbreviation: ED = emergency department.

* The y-axis range differs for different age groups to account for different numbers of ED visits by these groups and to facilitate visualization of changes over time.

† The National Syndromic Surveillance Program receives deidentified medical record information from approximately 71% of nonfederal EDs nationwide. To reduce artifactual impact from changes in reporting patterns, analyses were restricted to facilities with more consistent reporting of more complete data (coefficient of variation ≤40 and average weekly informative discharge diagnosis ≥75% complete during 2019–2021).
