Caring for musicians' ears: insights from audiologists and manufacturers reveal need for evidence-based guidelines.

OBJECTIVE: This study investigated clinical care delivered to musicians in Australia by audiologists and manufacturers of musicians' hearing protectors (MHP). DESIGN: Audiologists with experience treating musicians were invited to complete a survey on their service delivery. A second survey was administered to manufacturers of MHPs. STUDY SAMPLE: Four manufacturers of MHP and 31 audiologists completed the surveys. Post hoc analyses were performed comparing the responses of audiologists with more versus less clinical experience; and those with and without musical training. RESULTS: There was considerable variation in the audiological care provided to musicians. Only one-third of audiologists performed pure-tone audiometry prior to MHP fitting, and there was little consistency across the sample in relation to impression taking, preferred attenuation or selection of canal length. There was also significant variation in the manufacturers' approach to MHP, each of whom provided different recommendations regarding preferred impression techniques and material viscosity. CONCLUSIONS: The results of this study reveal lack of consistency across the hearing healthcare sector with respect to care of musicians' hearing, with potential to impact upon the satisfaction with, and usage of, MHP. There is need for evidence-based, best practice guidelines and training to support clinical audiologists in providing optimal care.

The clinical use of Arthur Boothroyd (AB) word lists in Australia: exploring evidence-based practice.

OBJECTIVE: Limited empirical investigation exists validating the use of Arthur Boothroyd (AB) word recognition materials within the Australian clinical context. The current research was undertaken to examine the evidence base and clinical implementation/interpretation of AB words in Australia. DESIGN: An on-line 22-question survey was e-mailed to members of the peak audiology professional body in Australia. STUDY SAMPLE: Three hundred and twelve responses were recorded between April and June 2015 from audiologists of a range of ages, working in various clinical settings. RESULTS: The survey results suggested audiologists use AB words on a wide range of clients from children <5 to adults ≥80 years, for diverse purposes including diagnosis of retrocochlear pathology, candidacy and validation of rehabilitative options, and client counselling. A majority of respondents reported typically administering one or two word lists per ear, and over 99% of audiologists utilised phonemic scoring. There was no consensus regarding what constitutes a significant difference between any two given scores. CONCLUSIONS: Wide variation exists in the administration and interpretation of AB words in Australia. There appears to be a mismatch between clinical utilisation of AB words and existing evidence-based empirical data. Further research is required to improve evidence-based audiologist training, and thereby current clinical use of AB words.

Practical guidelines to minimise language and cognitive confounds in the diagnosis of CAPD: a brief tutorial.

OBJECTIVE: To provide audiologists with strategies to minimise confounding cognitive and language processing variables and accurately diagnose central auditory processing disorder (CAPD). DESIGN: Tutorial. STUDY SAMPLE: None. RESULTS: Strategies are reviewed to minimise confounding cognitive and language processing variables and accurately diagnose CAPD. CONCLUSIONS: Differential diagnosis is exceedingly important and can be quite challenging. Distinguishing between two or more conditions presenting with similar symptoms or attributes requires multidisciplinary, comprehensive assessment. To ensure appropriate interventions, the audiologist is a member of the multidisciplinary team responsible for determining whether there is an auditory component to other presenting deficits or whether one condition is responsible for the symptoms seen in another. Choice of tests should be guided both by the symptoms of the affected individual, as established in an in-depth interview and case history, the individual's age and primary language, and by the specific deficits reported to be associated with specific clinical presentations. Knowing which tests are available, their strengths and limitations, the processes assessed, task and response requirements, and the areas of the central auditory nervous system (CANS) to which each test is most sensitive provides the audiologist with critical information to assist in the differential diagnostic process.

The Role of the Professional Supervisor in the Audiometric Testing Component of Hearing Conservation Programs.

: ACOEM believes that the functions of a professional supervisor in hearing conservation programs are part of the "core practice" of occupational medicine. This guidance emphasizes the role occupational medicine clinicians play in the supervision of audiometric surveillance conducted under the auspices of hearing conservation programs and reviews the regulatory and scientific basis and pertinent practices involved in this supervisory role.

Pediatric Hearing Aid Management: Challenges among Hispanic Families.

BACKGROUND: Hearing aid fitting in infancy has become more common in the United States as a result of earlier identification of hearing loss. Consistency of hearing aid use is an area of concern for young children, as well as other hearing aid management challenges parents encounter that may contribute to less-than-optimal speech and language outcomes. Research that describes parent hearing aid management experiences of Spanish-speaking Hispanic families, or the extent of their needs, is not available. To effectively support parent learning, in a culturally sensitive manner, providers may benefit from having a better understanding of the needs and challenges Hispanic families experience with hearing aid management. PURPOSE: The purpose of the current study was to describe challenges with hearing aid management and use for children from birth to 5 yr of age, as reported by Spanish-speaking parents in the United States, and factors that may influence hearing aid use. RESEARCH DESIGN: This study used a cross-sectional survey design. STUDY SAMPLE: Forty-two Spanish-speaking parents of children up to 5 yr of age who had been fitted with hearing aids. DATA COLLECTION AND ANALYSIS: Responses were obtained from surveys mailed to parents through early intervention programs and audiology clinics. Descriptive statistics were used to describe frequencies and variance in responses. RESULTS: Forty-seven percent of the parents reported the need for help from an interpreter during audiology appointments. Even though parents received information and were taught skills by their audiologist, many wanted to receive more information. For example, 59% wanted to know how to meet other parents of children who have hearing loss, although 88% had previously received this information; 56% wanted to know how to do basic hearing aid maintenance, although 71% had previously received instruction. The two most frequently reported hearing aid use challenges were fear of losing the hearing aids, and not seeing benefit from the hearing aids. Hearing aid use during all waking hours was reported by more parents (66%) when their child had a good day than when their child had a bad day (37%); during the previous two weeks, 35% of the parents indicated their child had all good days. CONCLUSIONS: Hispanic parents wanted more comprehensive information, concrete resources, and emotional support from the audiologist to overcome hearing aid management challenges. Understanding parents' perspectives, experiences, and challenges is critical for audiologists to provide appropriate support in a culturally sensitive manner and to effectively address families' needs.

Vestibular Assessment and Rehabilitation: Ten-Year Survey Trends of Audiologists' Opinions and Practice.

BACKGROUND: The past decade has yielded changes in the education and training of audiologists and technological advancements that have become widely available for clinical balance function testing. It is unclear if recent advancements in vestibular instrumentation or the transition to an AuD degree have affected audiologists' vestibular clinical practice or opinions. PURPOSE: The purpose of this study was to examine predominant opinions and practices for vestibular assessment (VA) and vestibular rehabilitation (VR) over the past decade and between master's- and AuD-level audiologists. METHOD: A 31-question survey was administered to audiologists via U.S. mail in 2003 (N = 7,500) and electronically in 2014 (N = 9,984) with a response rate of 12% and 10%, respectively. RESULTS: There was an increase in the number of audiologists providing vestibular services in the past decade. Most respondents agreed that audiologists were the most qualified professionals to conduct VA. Less than half of the surveyed audiologists felt that graduate training was adequate for VA. AuD-level audiologists were more satisfied with graduate training and felt more comfortable performing VA compared to master's-level audiologists. Few respondents agreed that audiologists were the most qualified professionals to conduct VR or that graduate training prepared them to conduct VR. The basic vestibular test battery was unchanged across surveys and included: calorics, smooth pursuit, saccades, search for spontaneous, positional, gaze and optokinetic nystagmus, Dix-Hallpike, case history, and hearing evaluation. There was a trend toward greater use of air (versus water) calorics, videonystagmography (versus electronystagmography), and additional tests of vestibular and balance function. CONCLUSIONS: VA is a growing specialty area in the field of audiology. Better training opportunities are needed to increase audiologists' knowledge and skills for providing vestibular services. The basic tests performed during VA have remained relatively unchanged over the past 10 yr.

Audiologist Practices: Parent Hearing Aid Education and Support.

BACKGROUND: Early identification of hearing loss has led to routine fitting of hearing aids in infants and young children. Amplification provides opportunities to optimize child development, although it also introduces challenges for parents to navigate. Audiologists have a central role in providing parents with support to achieve effective management strategies and habits. PURPOSE: The purpose of this study was to explore current practices of pediatric audiologists who work with children birth to 5 yr of age, regarding their support of parent learning in achieving effective hearing aid management, identify existing gaps in service delivery, and to determine if audiologists were receptive to receiving training related to effective approaches to provide counseling and support to parents. RESEARCH DESIGN: A cross-sectional, population-based survey was used. STUDY SAMPLE: Three hundred and forty-nine surveys were analyzed from pediatric audiologists who provided services to children birth to 5 yr of age. Responses were received from 22 states in the United States. DATA COLLECTION AND ANALYSIS: Responses were collected through the mail and online. Descriptive statistics were used to analyze the information. RESULTS: More than half (61%) of the audiologists in the study had been providing pediatric hearing aid services to children birth to 5 yr of age for >10 yr. Of the audiologists who reported monitoring hours of hearing aid use, the majority reported that they used data logging (90%). More than half of the audiologists (57%) who shared data logging with parents reported that they encountered defensiveness from parents when addressing hearing aid use. Information and skills that were not routinely provided by one-third to one-half of the audiologists included the following: how to get access to loaner hearing aids (30%), available hearing aid options/accessories (33%), available financial assistance (36%), how to teach hearing aid management to other caregivers (38%), how to do hearing aid maintenance (44%), and how to do a Ling 6 sound check (52%). Many audiologists reported they did not frequently collaborate with speech-language pathologists (48%), early interventionists (47%), or physicians (68%). More than half of the audiologists indicated a desire for more training in counseling skills, for all 14 items queried, to support parents with hearing aid management (53-79%), regardless of their previous training experience. CONCLUSIONS: For young children with hearing loss to achieve optimal benefit from auditory experiences for speech and language development, they need evidence-based, comprehensive, and coordinated hearing aid management. Audiologists have an important role for teaching information and skills related to hearing aids, supporting parent learning, and collaborating with other providers. Pediatric audiologists in this study recognized and desired the need for further training in counseling skills that can better prepare them to meet the emotional needs of parents in the hearing aid management process.
