Emergency department consultations for patients with neurological emergencies

Abstract

The spectrum of neurological emergencies that front-line physicians encounter is diverse. Appropriate assessment and neurological consultation is essential to good patient outcomes because many of these conditions depend on the rapid initiation of proper therapy. In this retrospective study, we reviewed patients for whom the emergency physician elected to consult a neurologist to categorize the types of complaints, resources utilized, patient disposition and final diagnoses. Of the 500 patients analyzed in our study, the most common chief complaints were focal weakness (22%), headache (18.2%), dizziness or vertigo (16%), and seizure (14.2%). The most common reasons for neurological consultation were specific symptom (70.6%), concern for a specific diagnosis (17.4%), specific radiologic finding (9.2%), and ambiguity in the diagnosis (2.8%). Overall stroke accounted for 18.6% of the cases in our study. Non-contrast brain computed tomography was the most common imaging study (72.2%), and 37.0% of patients received advanced neuroimaging. The presentation of patients varied as 47% presented without having been seen by another healthcare professional, 24% were referred to the emergency department (ED) following by some other outpatient provider for evaluation, and 29% were transferred from another ED. Patients with neurological emergencies are common and consume a disproportionate amount of resources in the ED. Emergency physician training must target the modern evaluation of patients with a large variety of neurological emergencies and place special emphasis on the evaluation of patients with weakness, seizures, headache, and dizziness.
