An audit of UK audiological practice in specialist paediatric oncology centres regarding hearing assessment of children at risk of ototoxicity due to chemotherapy.

OBJECTIVE: Platinum-based chemotherapy drugs are associated with substantial ototoxicity. The hearing of children treated with these drugs should be closely monitored. METHOD: A questionnaire was sent out to the 19 audiology departments associated with national paediatric cancer specialist centres in the UK looking at current practice in ototoxicity monitoring. RESULTS: Responses were received from 17 of 19 centres (89 per cent). All offered some form of audiometric monitoring service. Extended high-frequency testing (9-20 kHz) was only utilised by 7 services (29 per cent). A majority of respondents were reluctant to consider self-test devices in paediatric ototoxicity monitoring (n = 9; 53 per cent). Provision of long-term audiological follow up is sporadic with only 4 (23 per cent) respondents keeping all children with normal hearing under review once treatment is completed. CONCLUSION: While some good practice in paediatric ototoxicity was identified, opportunities exist to improve clinical practice and protocols, promote multidisciplinary team working and to utilise technologies such as extended high frequency and self-test audiometry.

Recomendaciones para la atención fonoaudiológica en las áreas de audiología y otoneurología en contexto COVID-19: una revisión narrativa / Recommendations for audiologist assistance in the areas of audiology and otoneurology in context COVID-19: a narrative review

La pandemia por el virus SARS-CoV-2 causante de la enfermedad COVID-19 se ha expandido rápidamente a nivel mundial. Las autoridades de salud pública han recomendado limitar las prestaciones de salud no esenciales, buscando el equilibrio entre el riesgo del retraso en el tratamiento y la potencial exposición al virus. En la mayoría de las prestaciones en las áreas de audiología y otoneurología no es posible cumplir con el distanciamiento físico recomendado y la duración de la atención puede superar los 45 minutos, factores que aumentan el riesgo de contagio para el profesional. El objetivo de la presente revisión es describir la evidencia actual sobre las recomendaciones de atención para las áreas de audiología y otoneurología en contexto COVID-19. Además de la búsqueda de artículos científicos en diversas bases de datos, se revisaron las recomendaciones emitidas por las principales asociaciones en el área. La información obtenida se organizó considerando cuatro aspectos clínicos relevantes: prestaciones, procedimientos, elementos de protección personal y limpieza de equipamiento e insumos. La evidencia científica y las sugerencias de las asociaciones están en constante actualización y algunos temas se han desarrollado escasamente. Sin embargo, las recomendaciones coinciden en priorizar la atención a distancia, extremar el uso de elementos de protección personal, implementar protocolos de higiene de manos y limpieza de equipos e insumos. También, se sugiere incorporar estrategias de comunicación alternativas al lenguaje oral con las personas con hipoacusia para facilitar la discriminación de la palabra.

The COVID-19 pandemic caused by the SARS-CoV-2 virus has rapidly spread worldwide. Public health authorities have recommended limiting non-essential healthcare, in search of a balance between the risk of delaying treatment and the potential exposure to the virus. Most services in the audiology and otoneurologyareas can easily exceed 45 minutes and it is not possible to keep the recommended physical distancing. Both factors increase the risk of professionals being infected. Therefore, the purpose of this review is to describe the current evidence about recommendations in audiology and otoneurology care in the context of COVID-19. In addition to the search of scientific articles in various databases, recommendations issued by the mainassociations in the area were consulted. The information was gathered considering four relevant clinical aspects: health careservices, procedures, personal protective equipment and the cleaning of equipment and supplies. Scientific evidence and suggestions made by associations are being constantly updated, and therefore there is limited content on some topics. However, the recommendations agree on prioritizing remote health care, increasing the use of personal protective equipment, implementing protocols for hand hygiene and for the cleaning of equipment and supplies. The incorporation communication strategies other than oral language to interact with people with hearing lossto facilitate speech discrimination is also recommended.

Validity of the Multiple Auditory Processing Assessment-2: A Test of Auditory Processing Disorder.

Purpose A normative study using the Multiple Auditory Processing Assessment-2 (MAPA-2; Schow et al., 2018) was recently completed. With access to these data, the authors extend that work and support a definite construct for auditory processing disorder (APD). The goal here is to examine MAPA-2 reliability and validity (construct, content, and concurrent). Evidence for the APD construct is further buttressed by measures of sensitivity and specificity. Results of MAPA-2 testing on children diagnosed with learning disability (LD), attention-deficit/hyperactivity disorder (ADHD), and specific language impairment (SLI) are included. Method Normative data (previously published as the MAPA-2) allowing derivation of these findings included a representative sample of 748 children (53% girls) ages 7-14 years tested by 54 speech-language pathologists and audiologists in 27 U.S. states. The authors examined diagnostic accuracy based on the American Speech-Language-Hearing Association (2005) criteria (index test) for confirmed cases of APD. The index was also used to identify listening problems for three other diagnostic categories (LD, ADHD, and SLI). Validated questionnaire responses from parents and school personnel allowed incorporation of functional measures widely supported in APD diagnosis but unavailable with other normative and sensitivity/specificity studies. Results Reliability and validity were both satisfactory, and diagnostic accuracy for an APD group of 18 (28% female) compared to the remaining typical group of 625 yielded 89% sensitivity and 82% specificity. The remaining three groups (LD, ADHD, and SLI), where comorbidity was expected to be about 50%, had APD-type listening problems with a prevalence ranging from 52% to 65%. Conclusions Current results provide important evidence for the construct of APD. The MAPA-2 can be administered by an audiologist or speech-language pathologist. A similar diagnostic protocol in Australia yielded positive therapeutic gains. Further study is encouraged to determine if the present positive findings will be found in future research.

Union of the European Phoniatricians' position statement on the exit strategy of phoniatric and laryngological services: staying safe and getting back to normal after the peak of coronavirus disease 2019 (issued on 25th May 2020).

BACKGROUND: The following position statement from the Union of the European Phoniatricians, updated on 25th May 2020 (superseding the previous statement issued on 21st April 2020), contains a series of recommendations for phoniatricians and ENT surgeons who provide and/or run voice, swallowing, speech and language, or paediatric audiology services. OBJECTIVES: This material specifically aims to inform clinical practices in countries where clinics and operating theatres are reopening for elective work. It endeavours to present a current European view in relation to common procedures, many of which fall under the aegis of aerosol generating procedures. CONCLUSION: As evidence continues to build, some of the recommended practices will undoubtedly evolve, but it is hoped that the updated position statement will offer clinicians precepts on safe clinical practice.

Audiological Considerations for Managing Mild Bilateral or Unilateral Hearing Loss in Infants and Young Children.

Purpose This clinical focus article describes considerations for recommending assistive hearing technology to infants and young children who have mild bilateral or unilateral hearing loss. These conditions present special challenges compared to bilateral permanent hearing losses that are moderate to profound in their degree in that the recommendation to proceed with technology is not as clear. Conclusion Current clinical practice guidelines and protocols for pediatric hearing aid fitting recommend managing these conditions on a case-by-case basis. Descriptions of key considerations for recommending assistive hearing technology for infants and young children with mild bilateral hearing loss or unilateral hearing loss are offered herein.

Meeting the Best Practice for Hearing Aid Verification in Children: Challenges and Future Directions.

Purpose This study examined the current pediatric amplification practice with an emphasis on hearing aid verification using probe microphone measurement (PMM), among audiologists in Klang Valley, Malaysia. Frequency of practice, access to PMM system, practiced protocols, barriers, and perception toward the benefits of PMM were identified through a survey. Method A questionnaire was distributed to and filled in by the audiologists who provided pediatric amplification service in Klang Valley, Malaysia. One hundred eight (N = 108) audiologists, composed of 90.3% women and 9.7% men (age range: 23-48 years), participated in the survey. Results PMM was not a clinical routine practiced by a majority of the audiologists, despite its recognition as the best clinical practice that should be incorporated into protocols for fitting hearing aids in children. Variations in practice existed warranting further steps to improve the current practice for children with hearing impairment. The lack of access to PMM equipment was 1 major barrier for the audiologists to practice real-ear verification. Practitioners' characteristics such as time constraints, low confidence, and knowledge levels were also identified as barriers that impede the uptake of the evidence-based practice. Conclusions The implementation of PMM in clinical practice remains a challenge to the audiology profession. A knowledge-transfer approach that takes into consideration the barriers and involves effective collaboration or engagement between the knowledge providers and potential stakeholders is required to promote the clinical application of evidence-based best practice.

Counseling Competencies in Audiology: A Modified Delphi Study.

Purpose Counseling practices in audiology play a critical role in helping patients and families understand, accept, and adjust to the dynamic impacts ear-related disorders have on their lives. The purpose of this study was to identify what competencies (i.e., knowledge, skills, and attitudes) are important for audiologists to possess to provide effective counseling in practice. Method A modified Delphi study design was used to survey a panel of 33 professionals with expertise in audiologic counseling from 5 different countries. In the 1st survey round, experts were asked to respond to 3 open-ended prompts. Responses were condensed and revised into items experts were asked to rate during the 2nd and 3rd survey rounds, on a 6-point Likert scale of importance. Results A total of 819 items were generated from the open-ended prompts. A total of 72 items were included in the 2nd and 3rd rounds of survey instruments. Consensus was met on 64 audiologic counseling competency items. Conclusions The competency items identified in this study reflect important knowledge, skills, and attitudes that are important to audiologic counseling. Items that met consensus in this study can inform competencies audiology students can acquire during graduate training. Practice guidelines in the field currently lack the necessary clarity and detail needed for implementation of counseling competencies in clinical education. Future research is needed to explore factors important for implementation of evidence-based counseling training in graduate audiology programs.

Clinical Protocol to Promote Standardization of Basic Tinnitus Services by Audiologists.

Purpose Clinical services for tinnitus are needed by millions of people annually. These services have not been standardized, and patients are vulnerable to receiving services that may appear legitimate but are not based on research evidence. The purpose of this clinical focus article is to promote standardization of tinnitus services by proposing an efficient clinical protocol for audiologists. Method The suggested clinical protocol is based primarily on research conducted at the National Center for Rehabilitative Auditory Research for the past 2 decades, with the focus on 2 randomized controlled trials completed recently that showed efficacy of an audiologic protocol involving hearing aids and brief tinnitus counseling. The protocol is mostly consistent with clinical practice guidelines that have been published. Results The two National Center for Rehabilitative Auditory Research randomized controlled trials revealed significant reduction of tinnitus functional effects for both hearing aids and "combination instruments" (hearing aids with a built-in sound generator), although there were no significant differences between devices. Existing clinical practice guidelines for tinnitus are summarized with respect to their common recommendations for assessment and intervention. Conclusions A defined clinical protocol is suggested for audiologists, which includes a case history, appropriate referral, audiologic assessment, use of the Tinnitus and Hearing Survey ( Henry, Griest, et al., 2015 ), brief tinnitus counseling, hearing aids or combination instruments as warranted, follow-up assessment, and criteria for determining if further tinnitus-specific services are needed. Use of this protocol can help to promote standardization of tinnitus practice by audiologists.

How Do We Know That Our Patients Have Benefitted From Our ENT/Audiological Interventions? Presented at the Annual Meeting of ADANO 2016 in Berlin.

: This short review article gives an introduction to some of the fundamental concepts and challenges facing measurement in hearing healthcare practice and research. The impact of hearing loss almost always extends beyond the sensory impairment itself, even when the measured degree of audiometric loss is mild. Yet, going beyond audibility, into the realm of measuring impact, takes us into a much more complex and less well-defined space. How does one therefore best measure the therapeutic benefit for evaluating efficacy or for clinical practice audit? Three case studies illustrate approaches to overcome such challenges. Each example highlights the importance of thinking critically about what it is one is seeking trying to measure, rather than selecting a questionnaire instrument based simply on its popularity or accessibility. We conclude by highlighting the important role that clinicians can play in collecting clinical data about their preferred instruments so that we have some evidence to inform decisions about good practice (content validity etc.). We would also strongly support open data sharing as we think that this is one of the best ways to make the most rapid progress the field.

An Assessment of the Change in Compliance of Observational Otology and Audiology Studies With the STROBE Statement Guidelines: A Systematic Review.

OBJECTIVES: Observational studies often represent the best available evidence for surgical practice. Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) recommendations were generated in 2007 with the aim of improving the quality of reporting. This study was designed to assess whether publication of STROBE guidelines has improved the quality of reporting in observational otology and audiology studies. DATA SOURCES: EMBASE and MEDLINE were searched using a comprehensive keyword search developed in conjunction with a scientific librarian. STUDY SELECTION: English language papers from six Otorhinolaryngology journals during two 6-month periods (2005 and 2016) were evaluated. DATA EXTRACTION: Two reviewers independently analyzed papers according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. DATA SYNTHESIS: Percentage scores for the two periods were compared using Mann-Whitney U test. CONCLUSIONS: Forty and 42 studies were returned for the 2005 and 2016 periods, respectively. The mean percentage of STROBE items that were met improved between 2005 and 2016 (58, 76%, respectively; p < 0.0001). Analysis indicated that improvements were greater in journals that endorsed STROBE guidelines (p = 0.02). This data suggests that STROBE has increased the reporting quality of observational studies; however, there are still significant further improvements to be met.

COMPARISON OF HEARING THRESHOLD ESTIMATION USING AUDITORY STEADY STATE RESPONSES AND BRAINSTEM AUDITORY EVOKED POTENTIALS IN CHILDREN.

Current recommendations proposed by pediatric audiologists are to commence with hearing amplification in children aged 6 months and above, after previous determination of the type and degree of hearing impairment and audiometric configuration. The goal of this study was to compare results obtained by click-evoked auditory brainstem response (c-ABR) and auditory steady state response (ASSR) in a group of children. This study included 68 children with different degrees of hearing impairment evaluated by c-ABR and ASSR. It is well-known that the c-ABR threshold highly correlates with behavioral hearing level at 2 kHz. In our study, the correlation between the c-ABR and ASSR thresholds in the whole sample was 0.58, 0.73, 0.97, 0.96, 0.95, 0.97; in the group of children with c-ABR thresholds up to 40 dBHL, it was 0.42, 0.73, 0.86, 0.74, 0.81, 0.81; and in the group with c-ABR thresholds worse than 40 dBHL, it was 0.46, 0.56, 0.89, 0.83, 0.85, 0.89 at 0.5, 1, 2, 4, 1-4, 2-4 kHz, respectively. Individual differences between the c-ABR and ASSR thresholds in the whole sample were up to 95, 90, 20, 25 dB at 0.5, 1, 2, 4 kHz, respectively. Study results indicated that there was strong correlation between the c-ABR and ASSR thresholds at 2, 4, 1-4, 2-4 kHz. The ASSR can be used as a valuable clinical tool and an excellent complementary method which, along with other audiologic techniques, provides more accurate hearing threshold estimation at an early age in children.

Analysis and interpretation of air-conducted ocular vestibular-evoked myogenic potentials (AC-oVEMP) - our experience in healthy adults.

BACKGROUND: Ocular vestibular-evoked myogenic potential (oVEMP) is one of recently introduced tests used to assess the function of the equilibrium system. It is still under research and no consensus has been reached yet. AIM: To analyze AC-oVEMP response parameters in subjects with no history of neurological or vestibular deficits. MATERIAL AND METHODS: The AC-oVEMPs collected from 50 subjects (100 ears) were analyzed in this prospective study for the response presence in the time domain, the latencies and amplitudes of the waves. RESULTS: No statistically significant differences were observed between the right and left ear considering both N1 latency, and amplitude. Significant differences were noted when comparing the groups <40 yo vs ≥40 yo (shorter latencies and higher amplitudes were observed in subjects <40). CONCLUSIONS AND SIGNIFICANCE: This thorough AC-oVEMP analysis in a group of healthy volunteers facilitated the proposal of reference ranges with a simultaneous indication of age-related differences. Shorter oVEMP latencies and higher amplitudes were observed in subjects <40 yo, while in the subjects ≥40 yo the latencies were longer and the amplitudes lower.

An Argument for Self-Report as a Reference Standard in Audiology.

BACKGROUND: The primary components of a diagnostic accuracy study are an index test, the target condition (or disorder), and a reference standard. According to the Standards for Reporting Diagnostic Accuracy statement, the reference standard should be the best method available to independently determine if the results of an index test are correct. Pure-tone thresholds have been used as the "gold standard" for the validation of some tests used in audiology. Many studies, however, have shown a lack of agreement between the audiogram and the patient's perception of hearing ability. For example, patients with normal audiograms may report difficulty understanding speech in the presence of background noise. PURPOSE: The primary purpose of this article is to present an argument for the use of self-report as a reference standard for diagnostic studies in the field of audiology. This will be in the form of a literature review on pure-tone threshold measures and self-report as reference standards. The secondary purpose is to determine the diagnostic accuracy of pure-tone threshold and Hearing-in-Noise Test (HINT) measures for the detection of a speech-recognition-in-noise disorder. RESEARCH DESIGN: Two groups of participants with normal pure-tone thresholds were evaluated. The King-Kopetzky syndrome (KKS) group was made up of participants with the self-report of speech-recognition-in-noise difficulties. The control group was made up of participants with no reports of speech-recognition-in-noise problems. The reference standard was self-report. Diagnostic accuracy of HINT and pure-tone threshold measures was determined by measuring group differences, sensitivity and specificity, and the area under the curve (AUC) for receiver-operating characteristic (ROC) curves. STUDY SAMPLE: Forty-seven participants were tested. All participants were native speakers of American English. Twenty-two participants were in the control group and 25 in the KKS group. The groups were matched for age. DATA COLLECTION AND ANALYSIS: Pure-tone threshold data were collected using the Hughson-Westlake procedure. Speech-recognition-in-noise data was collected using a software system and the standard HINT protocol. Statistical analyses were conducted using descriptive, correlational, two-sample t tests, and logistic regression. RESULTS: The literature review revealed that self-report has been used as a reference standard in investigations of patients with normal audiograms and the perception of difficulty understanding speech in the presence of background noise. Self-report may be a better indicator of hearing ability than pure-tone thresholds in some situations. The diagnostic accuracy investigation revealed statistically significant differences between control and KKS groups for HINT performance (p < 0.01), but not for pure-tone threshold measures. Better sensitivity was found for the HINT Composite score (88%) than pure-tone average (PTA; 28%). The specificities for the HINT Composite score and PTA were 77% and 95%, respectively. ROC curves revealed a greater AUC for the HINT Composite score (AUC = 0.87) than for PTA (AUC = 0.51). CONCLUSION: Self-report is a reasonable reference standard for studies on the diagnostic accuracy of speech-recognition-in-noise tests. For individuals with normal pure-tone thresholds, the HINT demonstrated a higher degree of diagnostic accuracy than pure-tone thresholds for the detection of speech-recognition-in-noise disorder.

A good practice guide for translating and adapting hearing-related questionnaires for different languages and cultures.

OBJECTIVES: To raise awareness and propose a good practice guide for translating and adapting any hearing-related questionnaire to be used for comparisons across populations divided by language or culture, and to encourage investigators to publish detailed steps. DESIGN: From a synthesis of existing guidelines, we propose important considerations for getting started, followed by six early steps: (1) Preparation, (2, 3) Translation steps, (4) Committee Review, (5) Field testing and (6) Reviewing and finalising the translation. STUDY SAMPLE: Not applicable. RESULTS: Across these six steps, 22 different items are specified for creating a questionnaire that promotes equivalence to the original by accounting for any cultural differences. Published examples illustrate how these steps have been implemented and reported, with shared experiences from the authors, members of the International Collegium of Rehabilitative Audiology and TINnitus research NETwork. CONCLUSIONS: A checklist of the preferred reporting items is included to help researchers and clinicians make informed choices about conducting or omitting any items. We also recommend using the checklist to document these decisions in any resulting report or publication. Following this step-by-step guide would promote quality assurance in multinational trials and outcome evaluations but, to confirm functional equivalence, large-scale evaluation of psychometric properties should follow.

Hearing aid fine-tuning based on Dutch descriptions.

OBJECTIVE: The aim of this study was to derive an independent fitting assistant based on expert consensus. Two questions were asked: (1) what (Dutch) terms do hearing impaired listeners use nowadays to describe their specific hearing aid fitting problems? (2) What is the expert consensus on how to resolve these complaints by adjusting hearing aid parameters? DESIGN: Hearing aid dispensers provided descriptors that impaired listeners use to describe their reactions to specific hearing aid fitting problems. Hearing aid fitting experts were asked "How would you adjust the hearing aid if its user reports that the aid sounds…?" with the blank filled with each of the 40 most frequently mentioned descriptors. STUDY SAMPLE: 112 hearing aid dispensers and 15 hearing aid experts. The expert solution with the highest weight value was considered the best solution for that descriptor. Principal component analysis (PCA) was performed to identify a factor structure in fitting problems. RESULTS: Nine fitting problems could be identified resulting in an expert-based, hearing aid manufacturer independent, fine-tuning fitting assistant for clinical use. CONCLUSIONS: The construction of an expert-based, hearing aid manufacturer independent, fine-tuning fitting assistant to be used as an additional tool in the iterative fitting process is feasible.
