Perspectives of emergency physicians, primary care physicians, and otolaryngologists on the diagnosis and treatment of acute vertigo

Abstract

URPOSE: This study aimed to explore the differences in diagnosis (Dix-Hallpike test; the head impulse, nystagmus, and the test of skew [HINTS] procedures; imaging modalities; and audiological battery) and treatment (pharmacological treatments and the Epley maneuver) of acute vertigo (AV) by examining the perspectives of otolaryngologists, emergency physicians (EPs), and primary care physicians (PCPs). METHOD: A total of 123 physicians (otolaryngologists [n = 40], EPs [n = 41], PCPs [n = 42]) were included in this study. This study was conducted using an online questionnaire created in Google Forms. The questionnaire included five demographic questions and eight questions assessing the diagnosis and treatment of four case scenarios (benign paroxysmal positional vertigo [BPPV], vestibular neuronitis, Meniere's disease [MD], and vertebrobasilar insufficiency). Multiple-response and chi-square tests were used to analyze the data. RESULTS: In the case of BPPV, 82.5% of otolaryngologists, 73.2% of EPs, and 59.6% of PCPs preferred the "Dix-Hallpike maneuver" (p = .067). In addition, 72.5% of otolaryngologists, 48.8% of EPs, and 47.6% of PCPs preferred the Epley maneuver for treatment in a case with BPPV (p = .032). It was found that physicians preferred the most (18.9%) "videonystagmography (VNG)-caloric" test for diagnosis in the MD case. There was a statistically significant difference in the intravenous serum therapy and rest, and Epley maneuver preferences of physicians for the treatment of cases with MD (p = .002 and p = .046). CONCLUSIONS: In this study, significant differences were found in the AV care provided by different specialties. Standardized education systems for AV (symposiums, congresses, scientific activities, etc., with multidisciplinary participation) may be beneficial for improving the diagnosis and treatment process of AV in our country.
