Health care resource utilization in patients with active epilepsy

Area of Science:

• Neurology
• Health Economics
• Public Health

Background:

• Active epilepsy impacts a significant portion of the population.
• Understanding health care resource utilization (HRU) is crucial for managing epilepsy costs.

Purpose of the Study:

• To evaluate health care resource utilization (HRU) in active epilepsy.
• To identify patterns and drivers of HRU across different epilepsy types.

Main Methods:

• Analysis of Thomson-Reuters insurance databases (2005-2007) covering 14 million individuals.
• Iterative expert classification to categorize patients by epilepsy type.
• Calculation of prevalence and HRU for each epilepsy type, with distance and principal components analysis.

Main Results:

• Prevalence of active epilepsy was 3.4 per 1,000; common types include generalized convulsive epilepsy and complex partial seizures.
• Average patient HRU included 10 physician visits, 24 diagnostic procedures, and >30 drug dispensings annually.
• Nonepilepsy-related HRU constituted the majority of utilization and was the primary source of variation, with distinct patterns for specific epilepsy types like grand mal status.

Conclusions:

• Active epilepsy prevalence is lower than a history of recurrent seizures.
• Nonepilepsy-related HRU significantly influences overall utilization and cost in epilepsy patients.
• Distinguishing between epilepsy-related and unrelated care is essential for accurate economic impact studies.
