The general practice management of epilepsy in Perth, Western Australia.

Ninety randomly selected general practitioners from the Perth metropolitan area completed a self-administered postal questionnaire aiming to examine the extent of their involvement with epilepsy and how closely their management mirrored best practice guidelines. GPs saw a median of 6 patients with epilepsy, mainly adults. They perceived complementary roles for GPs and neurologists: the GP providing ongoing support and education, monitoring treatment and making dosage adjustments; with the neurologist largely making the formal diagnosis and other management decisions. Only 42% regarded their knowledge of epilepsy as adequate for their practice. About half advised patients on the existence of the Epilepsy Association. Some respondents overestimated the usefulness of EEG. Plasma antiepileptic drug (AED) measurements were overvalued, with 69% of respondents performing plasma levels without regard to symptoms, and 20% would alter AED doses solely on the basis of plasma levels. GPs may tolerate very frequent seizures before referring their patients for more specialised evaluation.
