2.    Incidence and Prevalence:

•  What are the overall incidence of epilepsy in your population per 100,000 person-years and prevalence per 1,000 persons?

•  What are the incidence and prevalence by gender, race/ethnicity, age ranges (< 19, 19-64, > 64), and/or insurance status (public, private, none)? (Use Office of Management and Budget [OMB] classification for race/ethnicity, collapsing American Indian/Alaska Native, Native Hawaiian-Pacific Islander, and “two or more” into an “other” category to produce the following groups: Hispanic, non-Hispanic black/African American, non-Hispanic white, non-Hispanic Asian, and non-Hispanic other.)

•  What time period is covered by these incidence, prevalence, and demographic data?

•  Methods—short description of methods or algorithms used to make the estimates

•  Strengths and limitations of your type of data system to identify incidence and prevalence and at what level of granularity

3.    Comorbidities:

•  For those patients with prevalent epilepsy, what percentage also has comorbid conditions?

•  For those patients with incident epilepsy, what percentage also has preexisting comorbid conditions?

•  Methods—short description of methods or algorithms used to make the estimates

•  Strengths and limitations of your type of data system to link with comorbidities

4.    Health Care Services:

•  For those with psychiatric comorbid conditions (e.g., depression, anxiety, bipolar disorder, schizophrenia/psychosis), how many are receiving treatment for those conditions?

•  What is the percentage of patients in your epilepsy population receiving epilepsy care by type of provider (primary care, neurologist, epileptologist)? Provide this separately for incident and prevalent epilepsy.

•  What is the percentage of patients in your epilepsy population with seizure medication use (mono- versus polytherapy)? With antidepressant use? With both seizure medication and antidepres-
