Background and purpose
Patients with acute epileptic seizures form a large patient group in emergency neurology. This study aims to determine the burden caused by suspected epileptic seizures at different steps in emergency care.
Methods
A retrospective, cross‐sectional, population‐based (>1,000,000 inhabitants), 4‐year (2015–2018) study was conducted in an urban setting with a single dispatch centre, a university hospital‐affiliated emergency medical service (EMS), and five emergency departments (EDs). The study covered all adult (≥16 years old) emergency neurology patients receiving medical attention due to suspected epileptic seizures from the EMS and EDs and during hospital admissions in the Helsinki metropolitan area.
Results
Epileptic seizures were suspected in 14,364 EMS calls, corresponding to 3.3% of all EMS calls during the study period. 9,112 (63.4%) cases were transported to hospital due to suspected epileptic seizures, and 3368 (23.4%) were discharged on the scene. 6969 individual patients had 11,493 seizure‐related ED visits, accounting for 3.1% of neurology‐ and internal medicine‐related ED visits and 4607 hospital admissions were needed with 3 days’ median length of stay (IQR=4, Range 1‐138). Male predominance was noticeable at all stages (EMS 64.7%, EDs 60.1%, hospital admissions 56.2%). The overall incidence was 333/100,000 inhabitants/year for seizure‐related EMS calls, 266/100,000 inhabitants/year for ED visits and 107/100,000 inhabitants/year for hospital admissions. Total estimated costs were 6.8 million €/year, corresponding to 0.5% of all specialized healthcare costs in the study area.
Conclusions
Patients with suspected epileptic seizures cause a significant burden on the health care system. Present‐day epidemiological data are paramount when planning resource allocation in emergency services.
