This effect size "was surprising to us as it shows that receiving care in the area proximate to an epilepsy center is as important a factor as individual factors in determining access to specialty care," Mr. Schiltz said. "It is possible that neurologists or physicians who are in the area close to epilepsy centers are more aware and therefore refer patients to the epilepsy centers. We were also surprised that other community-level characteristics such as the poverty and employment rate were not significant predictors of access, as studies in other areas of clinical and health services research have found this to be the case."
The study’s overall findings, he added, make continued emphasis on highlighting awareness of epilepsy management among general neurologists and primary care physicians "as important as ever, as they serve as the main gatekeepers for patients to access specialized epilepsy care."
Mr. Schiltz acknowledged certain limitations of the study, including the fact that it relied on hospital billing records, which "do not contain detailed clinical information," he said. "In addition, we only identify specialized epilepsy centers based on the data from the National Association of Epilepsy Centers (NAEC). Some of the hospitals that provide specialized epilepsy care might not be a member of the NAEC. We looked at geographic factors at the county level, which may be somewhat crude in a state like California with diverse populations within counties."
Support for the study was provided by the Epilepsy Foundation, a training grant from the Agency for Healthcare Research and Quality, and a grant from the National Center for Research Resources. Mr. Schiltz received support for travel to the meeting from his receipt of an American Epilepsy Society Young Investigator Award.
Mr. Schiltz said that he had no relevant financial conflicts to disclose.
