Epilepsy Among Elderly Medicare Beneficiaries: A Validated Approach to Identify Prevalent and Incident Epilepsy.

ABSTRACT:

Uncertain validity of epilepsy diagnoses within health insurance claims and other large datasets have hindered efforts to study and monitor care at the population level.

Objectives

To develop and validate prediction models using longitudinal Medicare administrative data to identify patients with actual epilepsy among those with the diagnosis.

We used linked electronic health records and Medicare administrative data including claims to predict epilepsy status.

We then reconstructed the full sample using inverse probability sampling weig
