Incidence of idiopathic benign paroxysmal positional vertigo subtype by hospital visit type: experience of a single tertiary referral centre

Abstract

Objective To investigate the incidence of benign paroxysmal positional vertigo subtype by hospital visit type (i.e. out-patient department vs emergency room), in a single tertiary referral centre. Methods A total of 772 consecutive patients with benign paroxysmal positional vertigo were included. Using head-roll and Dix–Hallpike tests, benign paroxysmal positional vertigo subtype was determined as canalolithiasis posterior semicircular canal benign paroxysmal positional vertigo, geotropic horizontal semicircular canal benign paroxysmal positional vertigo or apogeotropic benign paroxysmal positional vertigo. Results The posterior semicircular canal benign paroxysmal positional vertigo patients who were evaluated via the out-patient department outnumbered those evaluated via the emergency room, while those with horizontal semicircular canal benign paroxysmal positional vertigo who were evaluated via the emergency room outnumbered those evaluated via the out-patient department. Conclusion A significantly higher proportion of patients who visited the emergency room had horizontal semicircular canal benign paroxysmal positional vertigo than posterior semicircular canal benign paroxysmal positional vertigo. These results suggest that the true incidence of horizontal semicircular canal benign paroxysmal positional vertigo might be higher than previously reported.

Guidelines for reasonable and appropriate care in the emergency department 3 (GRACE‐3): Acute dizziness and vertigo in the emergency department

“…Future work should focus on education and training of ED providers on appropriate application and interpretation of Dix–Hallpike test and treatment of BPPV. In addition, as providers become more familiar with pc‐BPPV and if subsequent data confirm recent studies suggesting that hc‐BPPV is more common in an early‐presenting population than previously thought, 3,61,181,182,237 learning about other variants, especially geotropic and apogeotropic hc‐BPPV, will allow correct management of a much larger proportion of BPPV patients (and thus, of all patients with acute dizziness).…”

“…After a lengthy debate about hc‐BPPV, the writing committee made a conscious decision to simplify our recommendations and to restrict them to pc‐BPPV (the most common type). Some committee members felt that a recommendation for hc‐BPPV should have been included because this variant constitutes an important minority of total BPPV patients, especially in acutely presenting patients in an ED population, 237 because hc‐BPPV patients are often more severely symptomatic than patients with pc‐BPPV 238 …”

Complicaciones neurológicas periféricas en pacientes adultos Post-Covid-19, Revisión sistemática

“…El diagnóstico de neuritis vestibular (VN) se dio a seis de las siete personas que fueron examinadas después Covid-19 (53). Se utilizó la prueba de Dix-Hallpike para determinar si el paciente experimentaba o no un episodio de (VPPB) (54). En relación con el tratamiento de disfunción eréctil, las opciones terapéuticas disponibles actualmente, por ejemplo, recomiendan un mayor tiempo dedicado al ejercicio, mantener una dieta equilibrada, consumir menos alcohol y drogas.…”

Change in Diagnosis of Benign Paroxysmal Positional Vertigo During COVID-19 Pandemic

“…We have recently reported that the incidence of BPPV subtypes differs according to the type of hospital visit, ie, whether the patient is evaluated at the outpatient department (OPD) vs emergency room (ER). 8 The coronavirus disease 2019 (COVID-19) pandemic has markedly impacted patient and provider lifestyles, including patterns of healthcare system use. During the severe crisis period, only emergency and oncology services were active in the tertiary referral medical center, as was the case in many other hospitals.…”
