Emergency departments may be overutilizing neuroimaging for epileptic seizures
from Health Imaging
Is neuroimaging being overused on seizure-related visits to the emergency department? Authors of a study published in Epilepsia believe so. In the study, authors analyzed 882 ED visits recorded at the Oregon Health & Science University in Portland and the Veteran’s Affairs Portland Health Care System. Each patient had been previously diagnosed with epilepsy and all visits were a result of seizures, with neuroimaging completed in 46 percent of cases. Out of the 381 scans performed, 41 included findings suggesting a new clinical problem; the other results were consistent with existing seizure-like abnormalities. Overall, imaging led to an acute change in management for 11 patients — two of which were later identified as false positives.
