[Hearing in the elderly: Employees' perspectives on hearing care in long-term care facilities. A qualitative study]. / Hören im Alter: Perspektiven von Mitarbeitenden auf die Hörversorgung in stationären Pflegeeinrichtungen.

Hearing in the elderly: Employees' perspectives on hearing care in long-term care facilities. A qualitative study Abstract: Background: Hearing impairment is common among the elderly. More than half of individuals 80 years and older exhibit severe hearing loss, and few retain good hearing performance. This impairment significantly affects both community participation and nursing care. Aim: This study aimed to examine the impact of hearing impairment on everyday life of employees and residents at long-term care facilities. We further sought to identify how employees perceive hearing care in order to identify potential for improvement. Methods: This sub-project of a larger study comprised guided focus groups with employees of long-term care facilities. The sample included six focus groups of nurses and nursing care assistants from long-term care facilities (n = 42). Collected data were analyzed using qualitative content analysis. Results: Hearing impairment hinders elderly resident participation in the nursing process and complicates daily communication between residents and nursing staff. Hearing impaired residents are less able to take part in group activities and tend to withdraw from the community. Lack of an effective hearing support structure renders hearing care services inaccessible to some residents. Conclusions: Optimized service structures, targeted assistance and training opportunities for employees specific to hearing impairment can provide sustainable hearing care for the elderly.

Hearing care services for adults with hearing loss in Malaysia: a scoping review.

OBJECTIVE: This scoping review aimed to identify knowledge gaps in relation to access to, and outcomes from, hearing care services for adults in Malaysia. DESIGN: Scoping review. STUDY SAMPLE: 1261 studies from 4 databases (PubMed, CINAHL, Embase and Scopus) and 7 studies from grey literature were identified. After removing duplicates, 647 studies were screened for title and/or abstract, and five studies met the criteria and were included. RESULTS: Audiologists reported offering a range of diagnostic assessment and rehabilitation services, including hearing aids, assistive listening devices, auditory training, and counselling. However, the uptake of hearing services was low; rates of hearing aid use among people with at least mild hearing loss were around 2.7%-4.4%; 6.5%-7.3% for those with at least moderate loss. There were no data on the outcomes from hearing services. CONCLUSIONS: This scoping review highlighted the limited uptake of hearing services among adults in Malaysia, despite the existence of services. Furthermore, it revealed a lack of information about the factors contributing to this limited uptake. To address the burden of hearing loss, there is an urgent need to identify barriers to access, improve access and uptake, and evaluate the benefits of adult hearing services in Malaysia.

[OLSA level control in monaural speech audiometry in background noise for the evaluation of the CI fitting result]. / OLSA-Pegelsteuerung bei monauraler Sprachaudiometrie im Störschall zur Evaluation des CI-Versorgungsergebnisses.

SCIENTIFIC BACKGROUND: Speech audiometry measurements under the influence of background noise are a fundamental part of evaluating the outcome of hearing care. As yet far, there are no recommendations for selecting a suitable method for adaptive speech audiometry measurements in background noise in cochlear implant (CI) care, so either the choice the adaptive level change of the speech signal (S) with constant noise (N) or the adaptive level change of N with constant S. OBJECTIVES: Do the measurement results of the monaural speechrecognition threshold in noise (SRT) with the Oldenburg Sentence Test (OLSA) depend on the choice of level control? MATERIAL AND METHODS: A total of 50 series of measurements with OLSA in noise and the Freiburg speech intelligibility test in quiet (FBE) on middle-aged CI patients from clinical routine. RESULTS: There is no significant difference in the measurement results with different level controls when the SRT is less than 5 [Formula: see text]. Below 55 % monosyllabic intelligibility in quiet, the SRT in noise becomes greater than 5 [Formula: see text]. CONCLUSION: From a clinical, audiological and methodological point of view, it is advisable to carry out the adaptive monaural speech intelligibility measurement with a constant speech signal at 65 [Formula: see text].

Advancing Equitable Hearing Care: Innovations in Technology and Service Delivery.

BACKGROUND: Hearing loss is a neglected global health priority affecting 1.5 billion persons. Global access to hearing care is severely limited with management options, like hearing aids, inaccessible to most. The cost and centralised nature of traditional service-delivery approaches in hearing care have undermined equitable access alongside poor awareness. SUMMARY: Recent innovations in digital and mHealth hearing technologies used by health workers through task shifting are enabling novel community-based services across the continuum of care. This narrative review explores technology-enabled hearing care in communities. We provide examples focused on our work over the past decade to explore more equitable hearing care across primary, secondary, and tertiary levels of prevention. KEY MESSAGES: Hearing health innovations have the potential to increase access to care, improve the quality of life for those affected by hearing loss, and reduce global costs associated with untreated hearing loss. More equitable hearing care is a global health priority that requires scalable service-delivery models enabled by innovative technologies within communities and integrated into public health initiatives including hearing health promotion.

Critical hearing experiences manifest differently across individuals: insights from hearing aid data captured in real-life moments.

OBJECTIVE: We investigated whether contrasts between situations of good and difficult listening experiences could be identified in objective hearing aid (HA) data, with the aim to use these insights for personalisation of hearing care. DESIGN: The participants were asked to fill out an ecological momentary assessment (EMA) report every time they encountered a good or difficult listening experience for a period of two weeks. During EMA reporting, the participants described their listening environment and why it was difficult while objective HA data describing the sound environment, activated HA features and gain were logged. STUDY SAMPLE: Sixteen experienced HA users completed the study. RESULTS: The group level objective HA data indicated that participants experienced difficulties in typical speech in noise environments. Data from 14/16 participants showed individual contrasts that were not seen on the group level, indicating that hearing challenges do not manifest themselves the same across persons. CONCLUSIONS: The objective data from real-life experiences add to our understanding of the difficulty of the situation. The fact that data between individuals varied so much emphasises the importance of considering each person as an individual when treating their hearing loss.

Association of Hearing Loss With Neuropsychiatric Symptoms in Older Adults With Cognitive Impairment.

Neuropsychiatric symptoms (NPS) in persons with dementia (PWD) are common and can lead to poor outcomes, such as institutionalization and mortality, and may be exacerbated by sensory loss. Hearing loss is also highly prevalent among older adults, including PWD. OBJECTIVE: This study investigated the association between hearing loss and NPS among community- dwelling patients from a tertiary memory care center. DESIGN, SETTING, AND PARTICIPANTS: Participants of this cross-sectional study were patients followed at the Johns Hopkins Memory and Alzheimer's Treatment Center who underwent audiometric testing during routine clinical practice between October 2014 and January 2017. OUTCOME MEASUREMENTS: Included measures were scores on the Neuropsychiatric Inventory-Questionnaire and the Cornell Scale for Depression in Dementia. RESULTS: Participants (n = 101) were on average 76 years old, mostly female and white, and had a mean Mini-Mental State Examination score of 23. We observed a positive association between audiometric hearing loss and the number of NPS (b = 0.7 per 10 dB; 95% confidence interval [CI]: 0.2, 1.1; t = 2.86; p = 0.01; df = 85), NPS severity (b = 1.3 per 10 dB; 95% CI: 0.4, 2.5; t = 2.13; p = 0.04; df = 80), and depressive symptom severity (b = 1.5 per 10 dB; 95% CI: 0.4, 2.5; t = 2.83; p = 0.01; df = 89) after adjustment for demographic and clinical characteristics. Additionally, the use of hearing aids was inversely associated with the number of NPS (b = -2.09; 95% CI -3.44, -0.75; t = -3.10; p = 0.003; df = 85), NPS severity (b = -3.82; 95% CI -7.19, -0.45; t = -2.26; p = 0.03; df = 80), and depressive symptom severity (b = -2.94; 95% CI: -5.93, 0.06; t = 1.70; p = 0.05; df = 89). CONCLUSION: Among patients at a memory clinic, increasing severity of hearing loss was associated with a greater number of NPS, more severe NPS, and more severe depressive symptoms, while hearing aid use was associated with fewer NPS, lower severity, and less severe depressive symptoms. Identifying and addressing hearing loss may be a promising, low-risk, non-pharmacological intervention in preventing and treating NPS.

Development of a public audiology service in Southern Malawi: profile of patients across two years.

RESULTS: Of the 61.6% of adults and 41.7% of children found to have some degree of hearing loss, 28.3% and 15.4% were fitted with hearing aids, respectively. The number of patients seen in 2017 (n = 1385) was 34% higher than that of 2016 (n = 914). CONCLUSION: This study found that demand for hearing services is increasing in this public sector Malawian audiology department but uptake of hearing aids for those in need is low. Future evaluation of service provision and treatment outcomes is needed. Results from this study can be used to inform the development of future audiology clinics in low resource settings.

Hearing care and management priority among parents of children with Down syndrome: a grounded theory.

OBJECTIVE: This study qualitatively explored the factors that influence how parents of children who are Deaf or hard-of-hearing with Down syndrome prioritise hearing care and management and developed an associated theory to explain that priority. DESIGN: Grounded theory was used for the purposes of this qualitative study. Data were collected using in-depth interviews which were analysed using a three-tiered qualitative coding process. STUDY SAMPLE: Eighteen mothers of children who are Deaf or hard-of-hearing with Down syndrome participated in this study. RESULTS: The higher the extent of engaged professional support, perception of benefit for child, parent activation, and family engagement, the higher the priority for hearing care and management will likely be among parents of children who are Deaf or hard-of-hearing with Down syndrome. CONCLUSIONS: Understanding how parents of children who are Deaf or hard-of-hearing with Down syndrome decide to prioritise hearing care and management has implications for how hearing health providers and others provide care to parents to enhance priority for hearing-related needs.

[Hearing care aspects in universal face mask use during the COVID 19 pandemic]. / Motivirovannost' k slukhoprotezirovaniyu v usloviyakh masochnogo rezhima pri pandemii COVID-19.

BACKGROUND: Typical cloth and medical masks, which are mandatory to wear during the COVID 19 pandemic, create visual barrier, obscure linguistic and nonverbal communication and interaction. Ski-slope hearing loss patients often don't admit their auditory insufficiency and do not use hearing aids due to acceptable speech intelligibility by using visual access to the mouth and other potential facial cues. PURPOSE: To assess the impact of universal face medical masks in public places on motivation to using hearing aids of patients with ski-slope hearing loss. PATIENTS AND METHODS: All the 504 patients (18-65 years old), who applied for < hearing care assistance and for the first time bought hearing aid were included. 266 patients (group A) applied from June to November 2020, when wearing facial masks was mandatory; 238 patients (group B) applied from June to November 2019, when wearing facial masks wasn't required. In both groups patients, who fulfilled the following criteria, were selected: 1) binaural mild to severe sensorineural ski-slope hearing loss lasting more than 3 years; 2) no progression of hearing loss within the last 3 years; 3) pure tone audiometry <20 dB HL at 125-1000 Hz frequencies; 4) hearing care with mono- or binaural hearing aids with the receiver-in-the-canal open-type. Questionnaires were administered to eligible patients in group A to assess the motivational components of acquiring hearing aids. RESULTS AND DISCUSSION: In group A, 74 (28%) patients received hearing aids according to the inclusion criteria, and in group B, 46 (19%) patients received hearing aids (p=0.033). Significant factors determining hearing aid acquisition were lack of visual contact when wearing a mask, communication difficulties in noisy environments and lack of intelligibility in a concert hall or lecture. CONCLUSION: Patients' motivation to hearing care grows in mandatory wearing facial masks conditions during the COVID-19 pandemic leading to an increase in patients using hearing aids.

Clients' perspective on quality of audiology care: Development of the Consumer Quality Index (CQI) 'Audiology Care' for measuring client experiences.

OBJECTIVE: Clients' perspective on the quality of audiology care has not been investigated thoroughly. Research has focused primarily on satisfaction with, and limitations of hearing aids. We developed a Consumer Quality Index (CQI) questionnaire 'Audiology Care' to systematically assess client experiences with audiology care. DESIGN: The CQI Audiology Care was developed in three steps: (1) posing open-ended questions through e-mail (n = 14), (2) two small-scale surveys assessing psychometric properties of the questionnaire (n = 188) and importance of quality aspects (n = 118), and (3) a large-scale survey (n = 1793) assessing psychometric properties and discriminatory power of the questionnaire. STUDY SAMPLE: People with complex hearing impairments and/or balance and communicative disorders who visited an audiology care centre during the past year. RESULTS: Important quality aspects were translated into seven reliable scales: accommodation and facilities, employees' conduct and expertise, arrangement of appointments, waiting times, client participation and effectiveness of treatment. Client experiences differed among the participating centres concerning accommodation and facilities, arrangement of appointments, waiting times and client participation. CONCLUSION: The CQI Audiology Care is a valid and reliable instrument to assess clients' experiences with audiology care. Future implementation will reveal whether results can be used to monitor and improve the quality of audiology care.

In-situ Audiometry Compared to Conventional Audiometry for Hearing Aid Fitting.

The use of in-situ audiometry for hearing aid fitting is appealing due to its reduced resource and equipment requirements compared to standard approaches employing conventional audiometry alongside real-ear measures. However, its validity has been a subject of debate, as previous studies noted differences between hearing thresholds measured using conventional and in-situ audiometry. The differences were particularly notable for open-fit hearing aids, attributed to low-frequency leakage caused by the vent. Here, in-situ audiometry was investigated for six receiver-in-canal hearing aids from different manufacturers through three experiments. In Experiment I, the hearing aid gain was measured to investigate whether corrections were implemented to the prescribed target gain. In Experiment II, the in-situ stimuli were recorded to investigate if corrections were directly incorporated to the delivered in-situ stimulus. Finally, in Experiment III, hearing thresholds using in-situ and conventional audiometry were measured with real patients wearing open-fit hearing aids. Results indicated that (1) the hearing aid gain remained unaffected when measured with in-situ or conventional audiometry for all open-fit measurements, (2) the in-situ stimuli were adjusted for up to 30 dB at frequencies below 1000 Hz for all open-fit hearing aids except one, which also recommends the use of closed domes for all in-situ measurements, and (3) the mean interparticipant threshold difference fell within 5 dB for frequencies between 250 and 6000 Hz. The results clearly indicated that modern measured in-situ thresholds align (within 5 dB) with conventional thresholds measured, indicating the potential of in-situ audiometry for remote hearing care.

Exploring the Performance of ChatGPT-4 in the Taiwan Audiologist Qualification Examination: Preliminary Observational Study Highlighting the Potential of AI Chatbots in Hearing Care.

Background: Artificial intelligence (AI) chatbots, such as ChatGPT-4, have shown immense potential for application across various aspects of medicine, including medical education, clinical practice, and research. Objective: This study aimed to evaluate the performance of ChatGPT-4 in the 2023 Taiwan Audiologist Qualification Examination, thereby preliminarily exploring the potential utility of AI chatbots in the fields of audiology and hearing care services. Methods: ChatGPT-4 was tasked to provide answers and reasoning for the 2023 Taiwan Audiologist Qualification Examination. The examination encompassed six subjects: (1) basic auditory science, (2) behavioral audiology, (3) electrophysiological audiology, (4) principles and practice of hearing devices, (5) health and rehabilitation of the auditory and balance systems, and (6) auditory and speech communication disorders (including professional ethics). Each subject included 50 multiple-choice questions, with the exception of behavioral audiology, which had 49 questions, amounting to a total of 299 questions. Results: The correct answer rates across the 6 subjects were as follows: 88% for basic auditory science, 63% for behavioral audiology, 58% for electrophysiological audiology, 72% for principles and practice of hearing devices, 80% for health and rehabilitation of the auditory and balance systems, and 86% for auditory and speech communication disorders (including professional ethics). The overall accuracy rate for the 299 questions was 75%, which surpasses the examination's passing criteria of an average 60% accuracy rate across all subjects. A comprehensive review of ChatGPT-4's responses indicated that incorrect answers were predominantly due to information errors. Conclusions: ChatGPT-4 demonstrated a robust performance in the Taiwan Audiologist Qualification Examination, showcasing effective logical reasoning skills. Our results suggest that with enhanced information accuracy, ChatGPT-4's performance could be further improved. This study indicates significant potential for the application of AI chatbots in audiology and hearing care services.

Scoping Review for a Global Hearing Care Framework: Matching Theory with Practice.

The hearing healthcare industry is evolving rapidly. A framework addressing provision options in contemporary hearing care could assist clinician and client navigate their options to find the most appropriate solution for each individual. A PRISMA approach was used followed by mapping, validation, and thematic analysis to produce a framework to better describe and discuss service and product delivery options in contemporary hearing care. No frameworks were identified to advise matching needs with current provision options in audiological care. Charting, mapping, and thematic analysis of the validation criteria and hearing care literature produced three core domains: Service, Channel, and Technology/Device. The framework developed in this review allows for an understanding of where innovation is occurring in hearing healthcare and differentiates between changes to technology, channel, and service. New questions open up such as whether one model is more effective than another or which model of hearing help is best for which type of person. This framework allows for the disambiguation of hearing health services, hearing loss technology, and the channel in which services and technology are delivered. It has potential to be a versatile and valuable addition to the industry of hearing healthcare.

[Hearing care network for early identification of delayed hearing loss in preschool children].

Objective:To establish a hearing care network for preschool children in Nanjing, to perform early identification and intervention for delayed hearing loss, and to evaluate the application effect of the hearing care network. Methods:Through the establishment of a hearing care network, hearing screening, diagnosis and follow-up of preschool children were conducted. Distortion product otoacoustic emissions（DPOAE） was adopted for primary hearing screening. Children who failed in the primary screening were re-screened within half a month. DPOAE and acoustic impedance test were used for hearing re-screening. Clinical diagnosis and audiological evaluation were performed for children who failed in the re-screening. Speech assessment, hearing aid intervention, and audio-speech follow-up were conducted for children diagnosed with delayed hearing loss. Results:Among 29 919 preschool children completing the hearing screening from May 2019 to September 2022, 3208 cases（10.7%） failed the primary screening and 1437 cases（47.7%） failed the re-screening. Total 747 children completed the hearing diagnosis, and 70 children were diagnosed with delayed hearing loss, with a detection rate of 0.23%. Among them, 20 cases were accompanied by language development delay, in which 12 cases received hearing aids and 2 cases received cochlear implantation. In addition, speech assessment and audiological follow-up were completed for 53 children. Conclusion:The hearing screening for preschool children is beneficial for early detection of children with delayed hearing loss and language development delay. Besides, the establishment of hearing care network is conducive to early identification and intervention of children with hearing loss.

Delta Variant of Covid-19 and Hearing Loss.

The Coronavirus Disease of 2019 has now become one of the biggest pandemics of all time. Under the influence of ongoing mutations and widespread geographical expansions, several variants have been reported. Among those, the B.1.617.2 variant, most commonly known as the 'Delta variant' of the coronavirus disease - 19, was first reported in the state of Maharashtra of India in December 2020 and have currently been detected in over 43 countries across six continents around the globe. The B.1.617.2 variant of COVID 19 is a more treacherous variant than the alpha variant due to the increased replication leading to higher viral loads and increased transmission with minimal literature reporting about vaccines' efficacy. In patients with the Alpha variant of COVID-19, hearing loss was an infrequent symptom seen, but on the other hand, the Delta variant happens to have a more frequent hearing loss as a symptom. The increased severity could be one of the reasons why hearing loss could be a typically seen symptom with high chances of occurrence of either a thrombosis, cross-reaction, labyrinthitis/neuritis, etc. and thus audiologists and otolaryngologists must be prepared for the post effect of the delta variant to evaluate and rehabilitate the individuals affected with hearing loss. The following article discusses the presence of hearing loss in individuals with delta variant of COVID 19 and the role of audiologists and otolaryngologists in hearing care.

[Analysis of clinical audiological characteristics in 868 children referred from maternal and child institutions].

Objective:To investigate the clinical audiological characteristics of children referred from maternal and child institutions and analyze the high risk factors of hearing loss, so as to provide scientific basis for further improvement of children's ear and hearing care. Methods:The subjects of this study were 868 children who were referred by maternal and child institutions in Beijing to the otology outpatient of Beijing Tongren Hospital, Capital Medical University for hearing diagnosis. All subjects underwent acoustic immittance, auditory brainstem response, distortion products otoacoustic emission and other audiological tests. Children were divided into groups according to the age of diagnosis: 0-<3 months group（242 cases）, 3-<6 months group（328 cases）, 6-<12 months group（180 cases）, ≥12 months group（118 cases）, the results of hearing diagnosis, hearing loss degree and types, the relationship between high risk factors and hearing loss in each group were compared and analyzed. Results:The age of diagnosis of 868 children was（7.13±8.29） months. 488 cases with hearing loss accounted for 56.22% and 380 cases with normal hearing accounted for 43.78%. Proportion of different degree of hearing loss of 792 ears from high to low was as follows: mild, 366 ears（46.21%）; moderate, 214 ears（27.02%）; severe, 151 ears（19.07%）; profound, 61 ears（7.70%）. There were statistically significant differences in the proportion of different hearing loss degree among 0-<3 months group, 3-<6 months group, 6-<12 months group and ≥12 months group（P<0.001）. Pairwise comparison between groups showed that the proportion of mild hearing loss of 0-<3 months group was higher than that in the other three groups（P<0.05）, there was no significant difference of moderate hearing loss among all groups（P>0.05）, the proportion of severe hearing loss of ≥12 months group was higher than that of 0-<3 months group（P<0.05）. The proportion of profound hearing loss with 0-<3 months group was lower than the other three groups（P<0.05）. In 792 ears with hearing loss, sensorineural hearing loss accounted for 67.42%, conductive hearing loss accounted for 20.71% and mixed hearing loss accounted for 11.87%. Among 98 cases with high risk factors for hearing loss, 58 cases（59.18%） were diagnosed with hearing loss. The incidence of hearing loss with high risk factors ranked from high to low was: craniofacial malformation（93.75%）, family history/congenital genetic syndrome（61.11%）, neonatal intensive care unit（NICU） hospitalization（46.43%） and others（20.00%）. Conclusion:Referrals from maternal and child institutions play an important role in the early detection of children with mild to moderate sensorineural hearing loss. Children with craniofacial malformation, family history/congenital genetic syndrome, hospitalization history of NICU and other high risk factors have a high incidence of hearing loss and should be attached with great importance.
