Diagnostic accuracy of the physical examination in emergency department patients with acute vertigo or dizziness: A systematic review and meta-analysis for GRACE-3.

BACKGROUND: History and physical examination are key features to narrow the differential diagnosis of central versus peripheral causes in patients presenting with acute vertigo. We conducted a systematic review and meta-analysis of the diagnostic test accuracy of physical examination findings. METHODS: This study involved a patient-intervention-control-outcome (PICO) question: (P) adult ED patients with vertigo/dizziness; (I) presence/absence of specific physical examination findings; and (O) central (ischemic stroke, hemorrhage, others) versus peripheral etiology. Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) was assessed. RESULTS: From 6309 titles, 460 articles were retrieved, and 43 met the inclusion criteria: general neurologic examination-five studies, 869 patients, pooled sensitivity 46.8% (95% confidence interval [CI] 32.3%-61.9%, moderate certainty) and specificity 92.8% (95% CI 75.7%-98.1%, low certainty); limb weakness/hemiparesis-four studies, 893 patients, sensitivity 11.4% (95% CI 5.1%-23.6%, high) and specificity 98.5% (95% CI 97.1%-99.2%, high); truncal/gait ataxia-10 studies, 1810 patients (increasing severity of truncal ataxia had an increasing sensitivity for central etiology, sensitivity 69.7% [43.3%-87.9%, low] and specificity 83.7% [95% CI 52.1%-96.0%, low]); dysmetria signs-four studies, 1135 patients, sensitivity 24.6% (95% CI 15.6%-36.5%, high) and specificity 97.8% (94.4%-99.2%, high); head impulse test (HIT)-17 studies, 1366 patients, sensitivity 76.8% (64.4%-85.8%, low) and specificity 89.1% (95% CI 75.8%-95.6%, moderate); spontaneous nystagmus-six studies, 621 patients, sensitivity 52.3% (29.8%-74.0%, moderate) and specificity 42.0% (95% CI 15.5%-74.1%, moderate); nystagmus type-16 studies, 1366 patients (bidirectional, vertical, direction changing, or pure torsional nystagmus are consistent with a central cause of vertigo, sensitivity 50.7% [95% CI 41.1%-60.2%, moderate] and specificity 98.5% [95% CI 91.7%-99.7%, moderate]); test of skew-15 studies, 1150 patients (skew deviation is abnormal and consistent with central etiology, sensitivity was 23.7% [95% CI 15%-35.4%, moderate] and specificity 97.6% [95% CI 96%-98.6%, moderate]); HINTS (head impulse, nystagmus, test of skew)-14 studies, 1781 patients, sensitivity 92.9% (95% CI 79.1%-97.9%, high) and specificity 83.4% (95% CI 69.6%-91.7%, moderate); and HINTS+ (HINTS with hearing component)-five studies, 342 patients, sensitivity 99.0% (95% CI 73.6%-100%, high) and specificity 84.8% (95% CI 70.1%-93.0%, high). CONCLUSIONS: Most neurologic examination findings have low sensitivity and high specificity for a central cause in patients with acute vertigo or dizziness. In acute vestibular syndrome (monophasic, continuous, persistent dizziness), HINTS and HINTS+ have high sensitivity when performed by trained clinicians.

Diagnostic accuracy of neuroimaging in emergency department patients with acute vertigo or dizziness: A systematic review and meta-analysis for the guidelines for reasonable and appropriate care in the emergency department.

BACKGROUND: Patients presenting to the emergency department (ED) with acute vertigo or dizziness represent a diagnostic challenge. Neuroimaging has variable indications and yield. We aimed to conduct a systematic review and meta-analysis of the diagnostic test accuracy of neuroimaging for patients presenting with acute vertigo or dizziness. METHODS: An electronic search was designed following patient-intervention-control-outcome (PICO) question-(P) adult patients with acute vertigo or dizziness presenting to the ED; (I) neuroimaging including computed tomography (CT), CT angiography (CTA), magnetic resonance imaging (MRI), magnetic resonance angiography (MRA), and ultrasound (US); (C) MRI/clinical criterion standard; and (O) central causes (stroke, hemorrhage, tumor, others) versus peripheral causes of symptoms. Articles were assessed in duplicate. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) was used to assess certainty of evidence in pooled estimates. RESULTS: We included studies that reported diagnostic test accuracy. From 6309 titles, 460 articles were retrieved, and 12 were included: noncontrast CT scan-six studies, 771 patients, pooled sensitivity 28.5% (95% confidence interval [CI] 14.4%-48.5%, moderate certainty) and specificity 98.9% (95% CI 93.4%-99.8%, moderate certainty); MRI-five studies, 943 patients, sensitivity 79.8% (95% CI 71.4%-86.2%, high certainty) and specificity 98.8% (95% CI 96.2%-100%, high certainty); CTA-one study, 153 patients, sensitivity 14.3% (95% CI 1.8%-42.8%) and specificity 97.7% (95% CI 93.8%-99.6%), CT had higher sensitivity than CTA (21.4% and 14.3%) for central etiology; MRA-one study, 24 patients, sensitivity 60.0% (95% CI 26.2%-87.8%) and specificity 92.9% (95% CI 66.1%-99.8%); US-three studies, 258 patients, sensitivity ranged from 30% to 53.6%, specificity from 94.9% to 100%. CONCLUSIONS: Noncontrast CT has very low sensitivity and MRI will miss approximately one in five patients with stroke if imaging is obtained early after symptom onset. The evidence does not support neuroimaging as the only tool for ruling out stroke and other central causes in patients with acute dizziness or vertigo presenting to the ED.

Prazosin for nightmares in serious illness.

Nightmares can be a distressing symptom in patients living with serious illness. Prazosin, a selective alpha-1 adrenergic antagonist, has been suggested to treat nightmares, with most data supporting its use in post-traumatic stress disorder (PTSD). We present the case of a 60-year-old woman with metastatic breast cancer who experienced healthcare-associated nightmares following hospitalisation. She did not meet diagnostic criteria for PTSD. Atypical antipsychotics and benzodiazepines were ineffective in controlling her nightmares, resulting in referral to our outpatient palliative medicine clinic. Prazosin was initiated alongside interdisciplinary psychosocial support, resulting in rapid resolution of her nightmares. To our knowledge, this is the first case to report on use of prazosin to manage nightmares in the outpatient palliative medicine setting.

COVID-19 communication resources in a major health system: development and dissemination.

OBJECTIVES: Early in the pandemic, institutional leadership recognised the importance of providing staff with practical, clinically based communication resources. This paper describes the process of cultivating and disseminating rapid communication resources across a multisite institution to assist others who may need to rapidly respond to communication challenges in the future. METHODS: In April 2020, the Mayo Healthcare Incident Command System charged the Center for Palliative Medicine with developing and disseminating clinical communication resources within several weeks. The Education Chair for the Center for Palliative Medicine created a COVID-19 communication task force composed of clinician-educators with expertise in serious illness communication from all three academic Mayo Clinic sites. The task force elected to focus on providing accessible, just-in-time online content curated from existing resources and adapted to situational needs. RESULTS: The task force developed one-page resources with example language on 16 topic areas. Topics included exploring patient values, discussing time-limited trials and making recommendations. The COVID-19 communication website was launched on 28 May, 6 weeks after the institutional request. CONCLUSIONS: Key takeaway lessons were the need for: (1) alignment with institutional need and priority, (2) rapid team formation with communication education experts across a variety of institutional geographic settings, (3) quick consensus on topic and content delivery to be practically helpful to clinicians, (4) collaboration with outside groups to use and adapt already available resources when possible and (5) early and iterative involvement with information specialists to help facilitate institutional dissemination.

Reconnecting: Strategies for Supporting Isolated Older Adults during COVID-19 through Tele-palliative Care.

The COVID-19 pandemic has resulted in unprecedented levels of social isolation which has negatively impacted older patients in particular on multiple levels. We present a case of an older patient with several complex psychosocial issues who was hospitalized and died from COVID-19. The social isolation required during the pandemic compounded patient and family stressors and diminished the patient's access to clinicians and to his usual support network and coping strategies. We describe how technology and tele-palliative care were utilized to reconnect the patient with clinicians and family and to provide clinical care that enhanced coping skills and support. Using telemedicine to restructure the approach to care was crucial in improving multiple domains of care and can be considered a resource for caring for older adults, especially during the challenging times brought on by the COVID-19 pandemic.

A Curriculum Innovation on Writing Simulated Patient Cases for Communication Skills Education.

Introduction: Facilitated communication practice with simulated patients (SPs) is a highly effective form of communication training. Unfortunately, little guidance exists on writing SP cases. Methods: We created a curriculum composed of a case-development workbook and case-writing session with input from national communication educators. In November 2017, we implemented the curriculum in a Teaching Communication Skills course for medical educators. Educators divided into four groups to write cases. Primary outcome was the number of criteria that cases fulfilled. Secondary outcomes were SP evaluation and educator-reported confidence and satisfaction. Results: Seventeen medical educators (including 15 fellows) completed the curriculum. Four new cases were analyzed against 24 criteria and compared to eight cases written by educators following a previous curriculum. An SP evaluated ease of portrayal for all 12 cases on a 5-point Likert scale (1 = poor, 5 = excellent). Educators completed precurriculum and postcurriculum surveys. Compared to the previous curriculum, cases based on the new curriculum incorporated 26% more case criteria (70% or 16.8 criteria/case vs. 96% or 23.0 criteria/case, p < .01). Ease-of-portrayal rating improved but did not differ statistically (mean: 2.8 vs. 4.5, p = .11). A moderate correlation was found between number of included case criteria and Likert-scale rating (rs = .61, p = .03). Pre- and postcurriculum, educators reported significant increases in confidence (mean: 1.9 vs. 4.0, p < .01) and high curricular satisfaction (mean: 4.8). Discussion: A case-development workbook and case-writing session increased the quality of newly developed SP cases as assessed by prespecified case criteria.

Development of Subspecialty-Specific Reporting Milestones for Hospice and Palliative Medicine Fellowship Training in the U.S.

Continuing the transition to competency-based education, Hospice and Palliative Medicine (HPM) fellowship programs began using context-free reporting milestones (RMs) for internal medicine subspecialties in 2014 but quickly recognized that they did not reflect the nuanced practice of the field. This article describes the development of 20 subspecialty-specific RMs through consensus group process and vetting by HPM educators. A workgroup of content experts used an iterative consensus building process between December 2017 and February 2019 to draft new RMs and create a supplemental guide that outlines the intent of each RM, examples of each developmental trajectory, assessment methods, and resources to guide educators. Program directors, program coordinators, and designated institutional officers were contacted directly to solicit feedback. Most respondents agreed or strongly agreed that each RM represented a realistic progression of knowledge, skills, and behaviors, and that the set of milestones adequately discriminated between meaningful levels of competency. Similarly, respondents felt that the supplemental guide was a useful resource. The result is a set of carefully developed and broadly vetted RMs that represent a progression of development for HPM physicians during one year of clinical fellowship training.

How Should Clinicians Respond to Requests from Patients to Participate in Prayer?

Over the past 20 years, physicians have shifted from viewing a patient's request for prayer as a violation of professional boundaries to a question deserving nuanced understanding of the patient's needs and the clinician's boundaries. In this case, Mrs. C's request for prayer can reflect religious distress, anxiety about her clinical circumstances, or a desire to better connect with her physician. These different needs suggest that it is important to understand the request before responding. To do this well requires that Dr. Q not be emotionally overwhelmed by the request and that she has skill in discerning potential reasons for the request.

Patient perspectives on opt-out HIV screening in a Guyanese emergency department.

In 2007, the WHO recommended that healthcare providers in areas of a generalised HIV epidemic perform HIV testing on all adults and adolescents presenting for healthcare. Studies regarding patient acceptability of opt-out testing, however, have reported wide variation in acceptance rates. This study examines patient-reported acceptability of such testing at the emergency department (ED) of Georgetown Public Hospital Corporation, the largest public hospital in Guyana. In June 2010, a convenience sample of 343 non-critical adult patients who presented to the ED were interviewed regarding potential acceptance of opt-out HIV testing, with 75.5% (95% CI 70.5-80.0%) stating they would accept testing should it be implemented in the ED. Of 12 patient characteristics, 3 had significant differences in acceptance rates on multivariate analysis: age; gender; and previous HIV testing. In this study, potential reasons for declining testing were also examined. The highest percentage of patient agreement was with the statements 'I have had an HIV test recently enough' (84%, 95% CI 74.0-91.4%) and 'I am not at risk for HIV/AIDS' (83%, 95% CI 73.0-90.4%). The results of this study indicate that the majority of patients in this setting would accept opt-out HIV testing, although some still had concerns regarding testing. Opt-out testing in the ED has the potential to facilitate national goals for increased testing and diagnosis.
