The most common vestibular disorders seen in the emergency department (ED) are benign paroxysmal positional vertigo (BPPV) and acute peripheral vestibulopathy (APV; i.e., vestibular neuritis or labyrinthitis). BPPV and APV are two very distinct disorders that have different clinical presentations that require different diagnostic and treatment strategies. BPPV can be diagnosed without imaging and is treated with canalith-repositioning maneuvers. APV sometimes requires neuroimaging by magnetic resonance imaging (MRI) to exclude posterior fossa stroke mimics and should be treated with vestibular sedatives and corticosteroids. We sought to determine if emergency physicians (EPs) apply best practices to diagnose and treat these common vestibular disorders. ⋯ Patients given a vestibular diagnosis in the ED may not be managed optimally. Patients given BPPV and APV diagnoses undergo imaging (predominantly CT) with equal frequency, suggesting overuse of CT (BPPV) and probably underuse of MRI (APV). Most patients diagnosed with BPPV are given meclizine, which is not indicated. Specific therapy for APV (corticosteroids) is probably underutilized. Educational initiatives and clinical guidelines merit consideration.

The objective was to estimate the national left-without-being-seen (LWBS) rate and to identify patient, visit, and institutional characteristics that predict LWBS. ⋯ Several patient, visit, and hospital characteristics are independently associated with LWBS. Prediction and benchmarking of LWBS rates should adjust for these factors.
