Age predicts the absence of caloric-induced vertigo.

Introduction: The absence of vertigo during the caloric test, despite a robust response, has been suggested to represent a central vestibular system phenomenon. The purpose of this investigation was to determine the prevalence of absent caloric-induced vertigo perception in an unselected group of patients and to assess possible predicting variables.

Methods: Prospective investigation of 92 unselected patients who underwent caloric testing.

Dual Eligibles' Experience of Care with North Carolina's Patient-Centered Medical Home.

Although individuals enrolled in both Medicare and Medicaid (dual eligibles) are among those with the nation's greatest need, at $300 billion per year, their care is also expensive and beset by quality problems. Previous research found problems associated with inadequate coordination of benefits and services; however, these studies have largely used quantitative approaches and focused on providers-few studies have explored the perspective of dual eligible patients. In an effort to improve care and reduce costs, North Carolina (NC) developed a Patient-Centered Medical Home (PCMH) model centered on a continuous relationship with a primary care provider who is responsible for coordination of services and addressing patients' health care needs by providing direct services or arranging care with other qualified professionals.

Drivers of Racial and Ethnic Disparities in Cardiac Rehabilitation Use: Patient and Provider Perspectives.

Cardiac rehabilitation (CR) use is lower for racial and ethnic minorities than White patients. The purpose of this study was to identify factors that drive this disparity at the system, provider, and patient levels. A mixed methods study combined descriptive analysis of 2007 Medicare claims data and thematic analysis of 19 clinician interviews, 8 minority patient focus groups and 8 one-on-one interviews with minority heart patients across three communities.

Effects of different musical stimuli in vital signs and facial expressions in patients with cerebral damage: a pilot study.

Background: Along history, music has been used in a variety of ways for therapeutic purposes and has long been recognized for its physiological and psychological effects. Music listening can be an effective nursing intervention, to enhance relaxation, provide distraction, and reduce pain.

Objectives: The aims of this study were to identify changes produced by different musical stimuli in blood pressure (BP), heart rate (HR), respiratory rate (RR), and oxygen saturations (SpO2) and to verify the influence of music listening on patients' facial expressions with severe cerebral damage.

Improving cardiovascular care through outpatient cardiac rehabilitation: an analysis of payment models that would improve quality and promote use.

Background: Much attention has been paid to improving the care of patients with cardiovascular disease by focusing attention on delivery system redesign and payment reforms that encompass the healthcare spectrum, from an acute episode to maintenance of care. However, 1 area of cardiovascular disease care that has received little attention in the advancement of quality is cardiac rehabilitation (CR), a comprehensive secondary prevention program that is significantly underused despite evidence-based guidelines that recommending its use.

Purpose: The purpose of this article was to analyze the applicability of 2 payment and reimbursement models-pay-for-performance and bundled payments for episodes of care--that can promote the use of CR.

Patterns of abnormality in cVEMP, oVEMP, and caloric tests may provide topological information about vestibular impairment.

Background: The cervical vestibular evoked myogenic potential (cVEMP) is recorded from the sternocleidomastoid muscle (SCM) and represents a stimulus-evoked attenuation of electromyographic (EMG) activity following activation of the saccule and inferior vestibular nerve. In addition to the cVEMP, it is possible to record a biphasic response from the infraorbital region following stimulation that is identical to that used to record the cVEMP. This response is known as the ocular VEMP (oVEMP).

The influence of unilateral saccular impairment on functional balance performance and self-report dizziness.

Background: Postural stability in humans is largely maintained by vestibular, visual, and somatosensory inputs to the central nervous system. Recent clinical advances in the assessment of otolith function (e.g.

Insensitivity of the "Romberg test of standing balance on firm and compliant support surfaces" to the results of caloric and VEMP tests.

Objective: The objective of this study was to assess the sensitivity, specificity, and positive and negative predictive value of the Romberg Test of Standing Balance on Firm and Compliant Support Surfaces (RTSBFCSS) for the identification of patients with vestibular system impairments affecting the horizontal semicircular canal, saccule, and/or inferior and superior vestibular nerves. The RTSBFCSS was developed for the National Health and Nutrition Examination Survey (NHANES) and was used recently to estimate the numbers of individuals aged 40 yr or older with vestibular system impairments among the general population of the United States.

Design: A retrospective analysis of the medical records of 103 consecutive patients aged 40 yr or older (mean age 59 ± 12 yr, 71 females) who had undergone vestibular assessment at the Balance Disorders Clinic at the Vanderbilt University School of Medicine.

Significant vestibular system impairment is common in a cohort of elderly patients referred for assessment of falls risk.

Background: Falls in elderly patients are associated with morbidity, mortality, and cost to the healthcare system. The development of falls risk assessment programs have represented a method of responding to what is known about injurious falls. The multidimensional assessments involve the comparison against normative data of a patient's performance on metrics known to influence the likelihood of future falls.

Psychological comorbidities and their relationship to self-reported handicap in samples of dizzy patients.

Factors such as anxiety, depression, somatic awareness, autonomic symptoms, and differences in coping strategies are known to affect dizziness handicap. We studied these factors in 63 consecutive "dizzy" patients. This sample was subgrouped into normals and patients with benign paroxysmal positional vertigo, compensated and uncompensated unilateral peripheral vestibular system impairment, or abnormal vestibular evoked myogenic potential as a single significant diagnostic finding.
