Referral characteristics of primary care physicians for seizure patients

To investigate primary care physicians' behavior with respect to referral patterns, antiepileptic drug (AED) initiation, and level of comfort in managing seizure patients.

A cross-sectional descriptive study design was used for collecting and analyzing data. A 20-item survey was developed and mailed to 8,195 primary care physicians including family practitioners, internal medicine physicians, and obstetrics-gynecologists throughout the state of Ohio; 504 primary care physicians that interact regularly with epilepsy patients responded to the survey.

Two patterns of referral emerged. Data showed that the majority (n = 382) of physicians refer >/=50% of their patients, but a minority of physicians (n = 122) refer <50% of their patients. Differences between the two groups existed in three of the four research questions asked: who initiates AED therapy, comfort level, and percentage of patients referred to a neurologist. Influence of managed care on decision making was not different between the two groups.

A minority of primary care physicians rate themselves very comfortable with seizure patients. These same physicians refer a minority of their patients to a neurologist. As a whole, however, primary care physicians refer a majority of their seizure patients to a neurologist. Neurologists evaluate most seizure patients because most primary care physicians claim not to be extremely comfortable with evaluation and treatment of seizures. We conclude that neurologists play an essential role in the treatment of most seizure patients.
