Cost-effectiveness analysis of responsive neurostimulation for drug-resistant focal onset epilepsy.

Modeling based on 9 years of available data demonstrates that RNS therapy for medically refractory epilepsy very likely falls within the range of cost-effectiveness, depending on method of utility estimation, variability in model inputs, and willingness-to-pay threshold. Several factors favor improved cost-effectiveness in the future. Given the increasing focus on delivering cost-effective care, we hope that this analysis will help inform clinical decision-making for this surgical option for refractory epilepsy.
