Saishoji Y, Yamamoto N, Fujiwara T, Mori H, Taito S. Epley manoeuvre's efficacy for benign paroxysmal positional vertigo (BPPV) in primary-care and subspecialty settings: a systematic review and meta-analysis. BMC PRIMARY CARE 2023; 24:262. [PMID: 38042776 PMCID: PMC10693044 DOI: 10.1186/s12875-023-02217-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Accepted: 11/21/2023] [Indexed: 12/04/2023]
Abstract
BACKGROUND Although previous studies have reported general inexperience with the Epley manoeuvre (EM) among general physicians, no report has evaluated the effect of EM on benign paroxysmal positional vertigo (BPPV) in primary care by using point estimates or certainty of evidence. We conducted this systematic review and meta-analysis and clarified the efficacy of EM for BPPV, regardless of primary-care and subspecialty settings. METHODS Systematic review and meta-analysis of randomised sham-controlled trials of EM for the treatment of posterior canal BPPV in primary-care and subspecialty settings. A primary-care setting was defined as a practice setting by general practitioners, primary-care doctors, or family doctors. A systematic search was conducted in January 2022 across databases, including Cochrane Central Resister of Controlled Trial, MEDLINE, Embase, Cumulative Index of Nursing and Allied Health Literature, World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov. Primary outcomes were the disappearance of subjective symptoms (vertigo), negative findings (Dix-Hallpike test), and all adverse events. We evaluated the certainty of evidence using the Grading of Recommendations, Assessment, Development and Evaluation approach. RESULTS Twenty-seven randomised controlled trials were identified. In primary-care settings, EM reduced the subjective symptoms [risk ratio (RR), 3.14; 95% confidence interval (CI), 1.96-5.02]; however, there was no applicable article for all adverse events. In the subspeciality setting, EM reduced the subjective symptoms (RR, 2.42; 95% CI, 1.64-3.56), resulting in an increase in negative findings (RR, 1.81; 95% CI, 1.40-2.34). The evidence exhibited uncertainty about the effect of EM on negative findings in primary-care settings and all adverse events in subspecialty settings. CONCLUSIONS Regardless of primary-care and subspecialty settings, EM for BPPV was effective. This study has shown the significance of performing EM for BPPV in primary-care settings. EM for BPPV in a primary-care setting may aid in preventing referrals to higher tertiary care facilities and hospitalisation for follow-up. TRIAL REGISTRATION The study was registered in protocols.io (PROTOCOL INTEGER ID: 51,464) on July 11, 2021.

Abstract
This third Guideline for Reasonable and Appropriate Care in the Emergency Department (GRACE-3) from the Society for Academic Emergency Medicine is on the topic adult patients with acute dizziness and vertigo in the emergency department (ED). A multidisciplinary guideline panel applied the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach to assess the certainty of evidence and strength of recommendations regarding five questions for adult ED patients with acute dizziness of less than 2 weeks' duration. The intended population is adults presenting to the ED with acute dizziness or vertigo. The panel derived 15 evidence-based recommendations based on the timing and triggers of the dizziness but recognizes that alternative diagnostic approaches exist, such as the STANDING protocol and nystagmus examination in combination with gait unsteadiness or the presence of vascular risk factors. As an overarching recommendation, (1) emergency clinicians should receive training in bedside physical examination techniques for patients with the acute vestibular syndrome (AVS; HINTS) and the diagnostic and therapeutic maneuvers for benign paroxysmal positional vertigo (BPPV; Dix-Hallpike test and Epley maneuver). To help distinguish central from peripheral causes in patients with the AVS, we recommend: (2) use HINTS (for clinicians trained in its use) in patients with nystagmus, (3) use finger rub to further aid in excluding stroke in patients with nystagmus, (4) use severity of gait unsteadiness in patients without nystagmus, (5) do not use brain computed tomography (CT), (6) do not use routine magnetic resonance imaging (MRI) as a first-line test if a clinician trained in HINTS is available, and (7) use MRI as a confirmatory test in patients with central or equivocal HINTS examinations. In patients with the spontaneous episodic vestibular syndrome: (8) search for symptoms or signs of cerebral ischemia, (9) do not use CT, and (10) use CT angiography or MRI angiography if there is concern for transient ischemic attack. In patients with the triggered (positional) episodic vestibular syndrome, (11) use the Dix-Hallpike test to diagnose posterior canal BPPV (pc-BPPV), (12) do not use CT, and (13) do not use MRI routinely, unless atypical clinical features are present. In patients diagnosed with vestibular neuritis, (14) consider short-term steroids as a treatment option. In patients diagnosed with pc-BPPV, (15) treat with the Epley maneuver. It is clear that as of 2023, when applied in routine practice by emergency clinicians without special training, HINTS testing is inaccurate, partly due to use in the wrong patients and partly due to issues with its interpretation. Most emergency physicians have not received training in use of HINTS. As such, it is not standard of care, either in the legal sense of that term ("what the average physician would do in similar circumstances") or in the common parlance sense ("the standard action typically used by physicians in routine practice").

Abstract
BACKGROUND Canalith repositioning maneuvers (such as the Epley maneuver) are recommended by specialty guidelines for management of benign paroxysmal positional vertigo (BPPV) yet are frequently underutilized in the emergency department (ED). METHODS We conducted a systematic review of systematic reviews to summarize the evidence of Epley maneuver for the treatment of posterior canal (pc) BPPV in any setting. We included systematic reviews of randomized controlled trials (RCTs) that compared Epley to control in adult patients with pc-BPPV. Titles, abstracts, and full texts were screened in duplicate. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) assessment was used to rate certainty of evidence. Odds ratios (OR) and 95% confidence intervals (CI) are reported. Meta-analysis of individual studies was conducted with random and fixed effects. RESULTS From 2,228 titles, 7 systematic reviews were selected for quality assessment. One review was of higher methodological quality, included only RCTs, and was the most current and comprehensive. Five of the 11 RCTs of the review, including 312 patients with pc-BPPV diagnosed by Dix-Hallpike, were relevant to our question. Meta-analysis of 4 RCTs (251 patients) showed the use of Epley (as compared to control) was associated with higher complete resolution of vertigo at 1 week (OR 7.19, CI 1.52 to 33.98, moderate certainty). Meta-analysis of 3 RCTs (195 patients) showed the use of Epley was associated with higher conversion to negative Dix-Hallpike at 1 week (OR 6.67, CI 1.52 to 33.98, moderate certainty). The number-needed-to-treat was 3. Meta-analysis of the outcomes at 1 month, and when observational studies were included, showed similar results. No serious adverse effects were reported. CONCLUSIONS Symptoms of pc-BPPV improve with the Epley maneuver. Emergency clinicians should become familiar with performing the Epley for BPPV. Further studies on ED implementation and clinician education of Epley are needed.

Abstract
IMPORTANCE Benign paroxysmal positional vertigo (BPPV) is a common cause of acute dizziness. Strong evidence exists for diagnosing BPPV using the Dix-Hallpike Test (DHT) and treating it with the canalith repositioning maneuver (CRM). Despite this, both are infrequently used in the emergency department (ED). OBJECTIVE As an early method to evaluate a BPPV-focused educational intervention, we evaluated whether an educational intervention improved ED provider performance on hypothetical stroke and BPPV cases delivered by vignette. DESIGN A randomized, controlled, educational intervention study in ED physicians. The intervention aimed to promote the appropriate use of the DHT and CRM. A BPPV vignette, a stroke-dizziness (safety) vignette, and vignette scoring schemes (higher scores indicating more optimal care) used previously established vignette methodology. SETTING We recruited participants at the exhibitor hall of an emergency medicine annual meeting. PARTICIPANTS We recruited 48 emergency physicians. All were board certified or residency trained and board eligible. All were engaged in the active practice of emergency medicine. None were trainees. INTERVENTIONS Intervention group: a narrated, educational presentation by computer followed by the clinical vignettes. CONTROL GROUP Received no educational intervention and completed the clinical vignettes-intended to mirror current clinician practice. MAIN OUTCOME MEASURE Primary endpoint: total score (out of 200 points) on a vignette-based scoring instrument assessing the performance of history, physical, and diagnostic testing on hypothetical stroke and BPPV cases. RESULTS The efficacy threshold was crossed at the interim analysis. The intervention group had higher performance scores compared with controls (113.2 versus 68.6, p < 0.00001). BPPV and safety subscores were both significantly higher in the intervention group. Sixty-two percent of the intervention group planned to use the DHT versus 29% of controls. After the vignette described characteristic BPPV nystagmus, 100% of the intervention group planned to use the CRM versus 17% of controls. CONCLUSIONS AND RELEVANCE The educational intervention increased provider performance in dizziness vignettes, including more frequent appropriate use of the DHT/CRM. These findings indicate the intervention positively influenced planned behavior. Future work is needed to implement and evaluate this intervention in clinical practice.

Implementation of evidence-based practice for benign paroxysmal positional vertigo: DIZZTINCT- A study protocol for an exploratory stepped-wedge randomized trial. Trials 2018; 19:697. [PMID: 30577834 PMCID: PMC6303863 DOI: 10.1186/s13063-018-3099-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2018] [Accepted: 12/02/2018] [Indexed: 11/18/2022] Open
Abstract
Background Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular disorder, and accounts for 8% of individuals with moderate or severe dizziness. BPPV patients experience substantial inconveniences and disabilities during symptomatic periods. BPPV therapeutic processes – the Dix-Hallpike Test (DHT) and the Canalith Repositioning Maneuver (CRM) – have an evidence base that is at the clinical practice guideline level. The most commonly used CRM is the modified Epley maneuver. The DHT is the gold standard test for BPPV and the CRM is supported by numerous randomized controlled trials and systematic reviews. Despite this, BPPV care processes are underutilized. Methods/design This is a stepped-wedge, randomized clinical trial of a multi-faceted educational and care-process-based intervention designed to improve the guideline-concordant care of patients with BPPV presenting to the emergency department (ED) with dizziness. The unit of randomization and target of intervention is the hospital. After an initial observation period, the six hospitals will undergo the intervention in five waves (two closely integrated hospitals will be paired). The order will be randomized. The primary endpoint is measured at the individual patient level, and is the presence of documentation of either the Dix-Hallpike Test or CRM. The secondary endpoints are referral to a health care provider qualified to treat dizziness for CRM and 90-day stroke rates following an ED dizziness visit. Formative evaluations are also performed to monitor and identify potential and actual influences on the progress and effectiveness of the implementation efforts. Discussion If this study safely increases documentation of the DHT/CRM, this will be an important step in implementing the use of these evidenced-based processes of care. Positive results will support conducting larger-scale follow-up studies that assess patient outcomes. The data collection also enables evaluation of potential and actual influences on the progress and effectiveness of the implementation efforts. Trial registration ClinicalTrials.gov, ID: NCT02809599. The record was first available to the public on 22 June 2016 prior to the enrollment of the first patients in October 2016. Electronic supplementary material The online version of this article (10.1186/s13063-018-3099-0) contains supplementary material, which is available to authorized users.

Abstract
BACKGROUND Emergency department (ED) use in the United States is expected to rapidly increase. Nearly half of all ED visits are classified as semiurgent or nonurgent, and many fall into the musculoskeletal category. Despite growing international evidence that patients are appropriately and safely managed by ED physical therapists in a time-efficient manner, physical therapist practice in EDs is not widely understood or utilized in the United States. To date, no studies have reported the impressions of ED physicians about this practice. OBJECTIVES The purposes of this study were: (1) to assess ED physicians' impressions of ED physical therapist practice 2 years after practice was initiated and (2) to determine whether physicians' impressions changed 7 years later. METHODS All ED staff physicians and medical residents at a level I trauma hospital were invited to complete a survey in 2004 and 2011. RESULTS In both years, a majority of physicians reported favorable impressions of ED physical therapist practice. Physical therapists were valued for educating patients about safety and injury prevention, providing appropriate gait training, assisting with disposition planning, and providing interventions as alternatives to pain medication. Many physicians supported standing physical therapist orders for certain musculoskeletal conditions. The most common concern was the additional time that patients spend in the ED for a physical therapist consult. LIMITATIONS The results of this study may not reflect the impressions of physicians in all EDs that employ physical therapists. CONCLUSIONS Emergency department physicians reported favorable impressions of ED physical therapist practice 2 years and 9 years following its implementation in this hospital. This study showed that ED physicians support standing physical therapist orders for certain musculoskeletal conditions, which suggests that direct triage to ED physical therapists for these conditions could be considered.

Abstract
Background and Purpose In contrast to the posterior- and horizontal-canal variants, data on the frequency and therapeutic management of anterior-canal benign paroxysmal positional vertigo (AC-BPPV) are sparse. To synthesize the existing body of evidence into a systematic review regarding the incidence and treatment of AC-BPPV. Methods Systematic search of medical databases employing predefined criteria, using the term "anterior canal benign paroxysmal positional vertigo." Results The electronic search retrieved 178 unique citations, 31 of which were considered eligible for further analysis. Analysis of the collected data revealed an estimated occurrence of AC-BPPV among benign paroxysmal positional vertigo patients of 3% (range 1-17.1%). No controlled therapeutic trials could be identified, and so the analysis was focused on uncontrolled case series. Treatment was categorized into three groups: Epley maneuver, Yacovino maneuver, and specific, nonstandard maneuvers described in individual articles. All three categories demonstrated success rates of over 75%, and the overall sample-size-weighted mean was 85.6%. Conclusions The present analysis demonstrated that AC-BPPV comprises about 3% of all BPPV cases. It can be treated safely using the Epley, Yacovino, and other maneuvers with rates of symptom resolution lying in the range of that reported for the other, more frequent canal variants. Multicenter controlled trials are needed in order to develop evidence-based guidelines for the treatment of AC-BPPV.

Abstract
OBJECTIVES/HYPOTHESIS Otologic complaints may place a significant burden on emergency departments (EDs) in the United States; however, few studies have comprehensively examined this discrete patient population. We aimed to identify utilization of EDs by patients with primary otologic complaints. STUDY DESIGN Retrospective analysis of the Nationwide Emergency Department Sample (NEDS) from 2009 through 2011. METHODS The NEDS database was queried for patient encounters with a primary otologic diagnosis based on International Classification of Diseases, Ninth Revision codes (380-389). Weighted estimates for demographics, diagnostic characteristics, socioeconomic status, and trends over time were extracted. Predictors of mortality and admission were determined by multivariable logistic regression. RESULTS A weighted total of 8,611,282 visits between 2009 and 2011 were attributed to otologic diagnoses, representing 2.21% of all ED visits. Stratified by patient age, otologic diagnoses encompassed 1.01% and 6.79% of all adult and pediatric ED visits, respectively. The majority of patients were treated and released (98.17%). The average age of patients presenting with an otologic complaint was 17.9 years (standard error = 0.23). Overall, 62.7% of patients who presented with an otologic complaint were 0 to 17 years old. The most common diagnoses among all age groups included otitis media not otherwise specified (NOS) (60.6%), infected otitis externa NOS (11.8%), and otalgia NOS (6.8%). CONCLUSIONS We provide a comprehensive overview of otologic complaints that are an overlooked diagnostic category in public health research. NEDS data demonstrate a significant number of visits related to otologic complaints, especially in the pediatric population, that are nonemergent. LEVEL OF EVIDENCE 4

Abstract
BACKGROUND An upward trend in the number of hospital emergency department (ED) visits frequently results in ED overcrowding. The concept of the emergency department observation unit (EDOU) was introduced to allow patients to transfer out of the ED and remain under observation for up to 24 hours before making a decision regarding the appropriate disposition. No study has yet been completed to describe physical therapist practice in the EDOU. OBJECTIVE The objectives of this study were: (1) to describe patient demographics, physical therapist management and utilization, and discharge dispositions of patients receiving physical therapy in the EDOU and (2) to describe these variables according to the most frequently occurring diagnostic groups. DESIGN This was a descriptive study of patients who received physical therapist services in the EDOU of Massachusetts General Hospital during the months of March, May, and August 2010. METHODS Data from 151 medical records of patients who received physical therapist services in the EDOU were extracted. Variables consisted of patient characteristics, medical and physical therapist diagnoses, and physical therapist management and utilization derived from billing data. Descriptive statistics were used to analyze data. RESULTS The leading EDOU medical diagnoses of individuals receiving physical therapist services included people with falls without fracture (n=30), back pain (n=27), falls with fracture (n=22), and dizziness (n=22). There were significant differences in discharge disposition, age, and total physical therapy time among groups. LIMITATIONS This was a retrospective study, so there was no ability to control how data were recorded. CONCLUSIONS This study provides information on common patient groups seen in the EDOU, physical therapist service utilization, and discharge disposition that may guide facilities in anticipated staffing needs associated with providing physical therapist services in the EDOU.

Abstract
BACKGROUND Benign paroxysmal positional vertigo (BPPV) is a mechanical peripheral vestibular disorder which may involve any of the three semicircular canals but principally the posterior. In as much as the literature has described theories to explain the mechanism of BPPV and also contains scholarly works that elucidate BPPV; its management remains an enigma to most clinicians. To this end, this work was aimed at outlining an evidence-based best practice for most common form of BPPV. MATERIALS AND METHODS A systematic review of the literature was conducted between 1948 and June 2011 in PubMed, Embase, Ovid, and Cochrane database through the online Library of the University of Cape Town. Seventy-nine worthy articles that addressed the study were selected on consensus of the two authors. CONCLUSION There is consensus for the use of canalith repositioning procedures as the best form of treatment for posterior canal canalolithiasis. However, successful treatment is dependent on accurate identification of the implicated canal and the form of lithiasis. Furthermore, clinicians should note that there is no place for pharmacological treatment of BPPV; unless it is to facilitate repositioning.

Abstract
BACKGROUND Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo. PURPOSE The purpose of this systematic review was to determine whether patients diagnosed with posterior canal (PC) BPPV, based on positional testing, and treated with a particle repositioning maneuver will show the resolution of benign paroxysmal positional nystagmus (BPPN) on the Dix-Hallpike Test performed 24 hours or more after treatment. DATA SOURCES Data were obtained from an electronic search of the MEDLINE, EMBASE, and CINAHL databases from 1966 through September 2009. STUDY SELECTION The study topics were randomized controlled trials (RCTs), quasi-RCTs, the diagnosis of PC BPPV, treatment with the particle repositioning maneuver, and outcome measured with a positional test 24 hours or more after treatment. DATA EXTRACTION Data extracted were study descriptors and the information used to code for effect size. DATA SYNTHESIS In 2 double-blind RCTs, the odds in favor of the resolution of BPPN were 22 times (95% confidence interval=3.41-141.73) and 37 times (95% confidence interval=8.75-159.22) higher in people receiving the canalith repositioning procedure (CRP) than in people receiving a sham treatment. This finding was supported by the results reported in 8 nonmasked quasi-RCTs. Studies with limited methodological quality suggested that a liberatory maneuver (LM) was more effective than a control intervention; there was no significant difference in the effectiveness of the LM and the effectiveness of the CRP; the self-administered CRP was more effective than the self-administered LM; and the CRP administered together with the self-administered CRP was more effective than the CRP administered alone. The Brandt-Daroff exercises were the least effective self-administered treatments. LIMITATIONS The limitations included the methodological quality of the studies, the lack of quality-of-life measures, and confounding factors in reporting vertigo. CONCLUSIONS Randomized controlled trials provided strong evidence that the CRP resolves PC BPPN, and quasi-RCTs suggested that the CRP or the LM performed by a clinician or with proper instruction at home by the patient resolves PC BPPN. There were no data on the effects of the maneuvers on outcomes relevant to patients.
