The decision analysis is based on a reasonable, though not comprehensive, set of parameters to simulate base cases representative of common first-ever seizure clinical scenarios, said editorialists Claire S. Jacobs, MD, PhD, and Jong Woo Lee, MD, PhD, both with the Department of Neurology at Brigham and Women’s Hospital in Boston.
Potentially the most controversial scenario addressed in the decision model, they noted, is the patient with low seizure recurrence risk but substantial quality of life decline upon recurrence. While that patient would not meet the commonly accepted 60% recurrence risk threshold that would indicate that treatment is warranted, this model favors immediate treatment because of the potentially disruptive effect of recurrence.
This study does not address important issues such as the cost of medication and patient preferences, they pointed out, and furthermore, QALYs can be difficult to integrate into clinical decision making.
Nonetheless, the findings are worth considering in clinical practice, the authors suggested. “At the very least, this study should, however subtly, shift the starting point of discussion with the patient toward a default of immediate, rather than deferred, treatment after a first unprovoked seizure and apparent absence of disease,” said Drs. Jacob and Lee.
The study was supported by NINDS.
