AB Objective: Determine the factors associated with epilepsy-related care costsBackground: Drivers of epilepsy-related care costs have not been systematically studiedDesign/Methods: We reviewed electronic medical records and cost data of epilepsy-treated patients between 2013–2016 from Partners Healthcare System’s Enterprise Data Warehouse. Total cost of care for epilepsy (TCC-E) was defined as sum of costs associated with all epilepsy-specific encounters (inpatient, outpatient, procedure, laboratory and hospital pharmacy) over 365 days. Changes in antiepileptic drug (AED) therapy, including additions/substitutions were assessed. Linear regression was used to model TCC-E; logistic regression modelled the likelihood of being in the top 5% and 1% of TCC-E. All models adjusted for demographic factors, insurance type, and neurologist accessResults: Data were available from 979 incident and 4392 prevalent cases. The mean and median TCC-E was $4768 and $602, respectively. TCC-E for incident cases was 104% higher than prevalent cases (p&lt;0.001). Compared to focal seizures, total costs were 88% (p&lt;0.001) higher for mixed seizures. Every additional Charlson Comorbidity Index (CCI) point was associated with 38% (p&lt;0.001) higher, and psychiatric comorbidity with 159% (p&lt;0.001) higher TCC-E. After controlling for AED generation(old vs new) and number of AEDs, calcium channel blockers (Pregabalin, Gabapentin, Ethosuximide) and SV2A binding agents (Levetiracetam) were associated with 64% and 98% higher TCC-E (p&lt;0.001) compared to sodium channel blockers (Carbamazepine, Phenytoin, Fosphenytoin, Oxcarbazepine, Lacosamide, Lamotrigine). TCC-E was 88% higher for every additional AED change event; substitution and addition events were associated with 127% and 83% higher TCC-E (p&lt;0.001). Incident status, comorbidities, and medication changes were significantly (p&lt;0.05) associated with odds of being in top 5% and top 1% of TCC-E.Conclusions: Epilepsy-related factors, comorbidities, and AED-related factors are significant predictors of TCC-E. Study limitations include cross-sectional design and non-inclusion of outpatient pharmacy costsStudy Supported by: UCB PharmaDisclosure: Dr. Kakarmath has nothing to disclose.
