ABSTRACT
OBJECTIVE: Rapid patient referral to epilepsy centers may facilitate subsequent disease-modifying surgical and non-surgical treatments. Delays of 15-18 years have been reported from time of epilepsy diagnosis to surgical evaluation in some settings, though patterns for timely guideline-concordant referrals within integrated care models are not well known and could inform strategies for optimizing guideline-concordant access.
METHODS: We performed a retrospective cohort study of 1088 patients undergoing epilepsy center evaluation from January 1, 2008 through June 30, 2023 in a Northern California integrated healthcare delivery system (IDS) with a Level 4 Epilepsy Center. Using electronic health record (EHR) data, we summarized time from diagnosis and other major care time points until first visit at the epilepsy center. A multivariate linear model was used to evaluate the relationship of select demographic, socioeconomic, and clinical characteristics with the time to first epilepsy center visit.
RESULTS: The mean times to epilepsy center visit from first prescription of an anti-seizure medication (ASM), diagnosis of epilepsy or seizures, and first visit with a general neurologist, were 3.9 years (SD = 4.5), 3.2 years (SD = 3.2) and 2.7 years (SD = 3.2), respectively, for the full cohort of patients prescribed any number of ASMs. Comparable time frames were seen for patients prescribed two or more ASMs at the time of first visit. Significantly longer time to epilepsy center visit was seen in patients with multiple ASMs prescribed, a concordant diagnosis of developmental delay, and those age 40 and above. Longer times to epilepsy center visit were not seen among patients with psychiatric comorbidities, public health insurance coverage, and among patients in traditionally underserved groups.
CONCLUSIONS: Patients evaluated at an epilepsy clinic within an IDS system did so within less than four years of diagnosis and initial treatment, with few disparities by demographics or comorbidities. Future studies can identify specific health system features that are key to shorter time frames to test transferable strategies to reduce time to epilepsy centers.
