Cost-benefit of epilepsy surgery

Area of Science:

• Neurosurgery
• Health Economics
• Epileptology

Background:

• Epilepsy Surgery (ES) presents a high direct cost, necessitating evaluation of its cost-benefit.
• Advancements in MRI technology and surgical techniques improve ES accuracy and reduce procedure duration.
• Societal gains from reduced production loss are a key consideration in ES cost-benefit analyses.

Purpose of the Study:

• To evaluate the cost-benefit of Epilepsy Surgery (ES) by assessing societal gains from reduced production loss.
• To analyze the economic impact of ES, considering direct costs against postoperative savings and long-term indirect cost reductions.
• To determine the health economic justification of re-operation for epilepsy.

Main Methods:

• Cost-benefit analysis comparing ES with anti-epileptic drug (AED) treatment.
• Evaluation of seizure freedom rates (45-90% for resective procedures, 45-50% for re-operation).
• Assessment of impact on employment, education, cognition, and quality of life.

Main Results:

• Successful ES leads to significant improvements in employment and income, particularly with early intervention in children.
• ES is more cost-effective than AED treatment alone when measured by seizure-free rates.
• Re-operation for epilepsy is health-economically justified, yielding seizure freedom in 45-50% of cases.
• While ES can improve quality of life, cognitive impairment post-surgery limits its overall benefit.

Conclusions:

• Epilepsy surgery is a cost-effective intervention with substantial long-term economic and societal benefits, especially when performed early.
• Successful surgical outcomes, including seizure freedom and improved employment, justify the initial investment in ES.
• Further research into optimizing ES outcomes and minimizing adverse effects like cognitive impairment is warranted.
