A Comparison of Clinical Practice Guidelines in the Initial Pharmacological Management of New-Onset Epilepsy in Adults

OBJECTIVES: Clinical practice guidelines (CPGs) are intended not only to provide supportive information for health care providers but also to act as a guide for health care policy decisions.

Sumario:OBJECTIVES: Clinical practice guidelines (CPGs) are intended not only to provide supportive information for health care providers but also to act as a guide for health care policy decisions. However, extant CPGs do not always reach the same conclusions. The objective of this study was to compare recommendations for initial pharmacological treatment of new-onset epilepsy in adults as stated within published CPGs. METHODS: We performed a systematic review of CPGs, which were published by prominent national organizations between January 2000 and June 2005, regarding the initial pharmacological treatment of epilepsy in adults. RESULTS: Five CPGs and 1 evidence report were identified that focus on pharmaceutical management in epilepsy. The 3 guidelines most relevant to the question of new-onset epilepsy treatment in adults were developed by the American Academy of Neurology (AAN), Scottish Intercollegiate Guidelines Network (SIGN), and National Institute for Health and Clinical Excellence (NICE). AAN recommends the use of both recently introduced antiepileptic drugs (AEDs: gabapentin, lamotrigine, topiramate, and oxcarbazepine) and standard agents (carbamazepine, phenytoin, valproic acid/divalproex, and phenobarbital) in newly diagnosed epilepsy, i.e., a nontiered approach. Alternatively, NICE recommends using newer AEDs (lamotrigine, topiramate, and oxcarbazepine) only in patients who derive no benefit from older agents a tiered approach. SIGN notes that all AEDs licensed for monotherapy have similar efficacy in newly diagnosed epilepsy a recommendation for a nontiered approach. The newer AEDs (lamotrigine and oxcarbazepine) are recommended as first-line initial treatment as are standard agents (carbamazepine and valproic acid/divalproex). The NICE guideline includes economic and quality-of-life evidence in their recommendations while AAN and SIGN do not. In these regards, current data fails to show superiority for newer agents. CONCLUSIONS: In the past 5 years, several CPGs have been published in epilepsy management. Only 3 guidelines have explicit recommendations for initial pharmacological treatment of adults with epilepsy. With some variation regarding which medications are recommended from each group, all CPGs promote standard and newer AEDs as having similar clinical efficacy. Until efficacy, quality of life, or cost data for the newer agents demonstrates a superior outcome, older AEDs remain viable options as first-line for monotherapy in newly diagnosed patients and may provide cost benefits over newer agents.
