Epilepsy Surgery Recommendations Varied Across Pediatric Centers

What was studied

Researchers studied how often children were not recommended for epilepsy surgery and whether recommendations differed among epilepsy centers. The study included 2,480 patients ages 0–18 who underwent an initial surgery evaluation and had a documented decision at 29 centers.

The researchers compared patient and evaluation features and used statistical models to quantify differences among centers after accounting for patient characteristics.

What they found

Overall, 532 children, or 21%, were not recommended for surgery. The median center rate was 17%, with the middle half of centers ranging from 10% to 28%.

Not being recommended for surgery was associated most strongly with having seizures monthly or less often, having a non-structural cause of epilepsy, and taking two or fewer anti-seizure medications. Even after accounting for patient characteristics, otherwise similar children had a median twofold difference in the odds of not being recommended for surgery when evaluated at different centers. The authors suggest that institutional decision-making contributes to this variation.

Limits of the evidence

This observational study identified associations but cannot establish why centers made different decisions. The abstract does not describe each center’s criteria or the individual reasons for recommendations. It also does not report later treatment choices, seizure outcomes, or whether recommending or not recommending surgery was appropriate for each child.

For families and caregivers

The findings suggest that epilepsy surgery recommendations may vary partly according to the center performing the evaluation, even among children with similar clinical characteristics. The study does not show that every child should have surgery or that any center’s decisions were right or wrong.

What to watch next

Further research could examine how centers make surgical candidacy decisions and whether differences in recommendations are associated with later treatment choices or outcomes.

Terms in this summary

drug-resistant epilepsy

Epilepsy in which seizures continue despite treatment with anti-seizure medications.

structural cause

A visible change or abnormality in the brain that may be related to seizures.

anti-seizure medication (ASM)

A medicine used to prevent or reduce seizures.

odds ratio

A measure comparing the odds of an outcome between groups; a value above 1 indicates higher odds in the group being studied.

confidence interval

A range expressing uncertainty around a study estimate.

mixed-effects model

A statistical method used here to account for both patient characteristics and differences among centers.

median odds ratio

A measure of how much the odds of an outcome typically differ between centers for otherwise similar patients.

intraclass correlation coefficient

A measure estimating how much of the overall variation is associated with differences between centers.
