Decision support system for the selection of an ITE or a BTE hearing aid

The purpose of this research is to mine a large set of heterogeneous audiology data to create a decision support system (DSS) to choose between two hearing aid types (ITE and BTE aid). This research is based on the data analysis of audiology data using various statistical and data mining techniques. It uses the data of a large NHS (National Health Services, UK) facility. It uses 180,000 records (covering more than 23,000 different patients) from a hearing aid clinic. The developed system uses an unconventional method to predict hearing aid type for a patient and it can be used as a second opinion by audiologists for complex cases. After modifying the system to take account of the feedback from a professional audiologist, the success rates obtained were in the ranges 63 to 66 percent. In this research an automatic system was developed to choose between an ITE or a BTE hearing aid type with an explanation facility that can be used as a second opinion by audiologist in cases where the choice of an ITE or a BTE hearing aid is not clear cut. This analysis of audiology data and DSS will provide supplementary information for audiology experts and hearing aid dispensers. This type of system may also be of interest to manufacturers of hearing technologies in using as a ready means for their telephone customer services staff to check data, discovering data in audiology records will also be good for general awareness about the suitability of hearing aid type

Development of image-based surgical planning software for bone-conduction implants

The BONEBRIDGE bone-conduction device is used to treat conductive and mixed hearing losses. The size of its floating mass transducer (FMT) can preclude implantation in certain anatomies, necessitating comprehensive surgical planning. Current techniques are time consuming and difficult to transfer to the operating room. The objective of this thesis was to develop software for calculating skull thickness to the dura mater to find locations for the FMT and to the first air cells which guarantee sufficient bone for the implant screws to grasp. Temporal bone computed tomography (CT) images were segmented and processed and custom Matlab code was written to generate and test thickness colormaps. For validation, measurements performed by a trained otologist were compared to the algorithm estimations achieving sub-millimeter accuracy. Results suggest this software can be used in the surgical workflow to automate thickness estimation and aid in finding an ideal location for the BONEBRIDGE device and screws

Knowledge is power: improving outcomes for patients, partners, and professionals in the digital age

Purpose The aim of this research was to develop and evaluate methods to address poor knowledge of hearing aids, hearing loss, and communication in patients, partners, and nonaudiologic health and social care professionals. Method An interactive multimedia educational program (C2Hear) has been co-produced with hearing aid users and audiologists to provide high-quality information and demonstrate complex concepts relating to hearing aids and communication. Results A randomized controlled trial showed numerous benefits for first-time hearing aid users that included better knowledge and skill, and increased hearing aid use and satisfaction. Patients reported that C2Hear was highly useful, enjoyable, and preferable to written information. C2Hear Online is now freely available on YouTube and has global reach, well in excess of 150,000 views. Further developments include a version for communication partners, which showed that joint-working between hearing aid users and their communication partners resulted in joint responsibility for communication that facilitated communication behaviors. In addition, a behavior theory-driven version for use with mobile technologies (m2Hear) has been designed to be tailored to the needs of individual hearing aid users. m2Hear includes more activities/interaction to maximize user engagement and learning. Finally, C2Hear has been used to improve hearing-related knowledge in other health and social care professionals, such as carehome assistants. Conclusion This range of educational programs and tools aims to improve knowledge and skills, leading to better outcomes for patients, partners, and health care professionals

Social representation of hearing aids: Cross-cultural study in India, Iran, Portugal, and the United Kingdom

This article was published in the following Dove Press journal: Clinical Interventions in Aging and available at http://dx.doi.org/10.2147/CIA.S86108Background: The current study was aimed at understanding the social representation of hearing aids in India, Iran, Portugal, and the United Kingdom. We also compared these results to explore the cross-cultural differences and similarities among these countries. Methods: The study involved a cross-sectional design, and the data were collected from four different countries using the snowball sampling method. Data were analyzed using a content analysis to identify the most-similar categories of responses reported, a co-occurrences analysis to see which of these categories are reported commonly, and a chi-square analysis to study if there was any association between positive, neutral, and negative connotations among participants in different countries. Results: The current study revealed four different social representations of hearing aids from India, Iran, Portugal, and the United Kingdom, and also a global index. Conclusion: The study results provide very useful insights into how hearing aids are represented in the society. These findings may have important implications for public education and also for manufacturers from the viewpoint of designing and marketing hearing aids in different countries

An integrated knowledge translation experience: Use of the Network of Pediatric Audiologists of Canada to facilitate the development of The University of Western Ontario Pediatric Audiological Monitoring Protocol (UWO PedAMP v1.0).

The goals of this project were: (1) to determine the important factors that influence implementation of evidence-based practice by Canadian audiologists; and (2) to utilize the knowledge-to-action process (Graham et al., 2006) during the development of a guideline for outcome measures to evaluate the auditory development and performance of young children who wear hearing aids, to facilitate clinical uptake and identify barriers to implementation (Bagatto, Moodie & Scollie, 2010; Bagatto et al., 2011; Bagatto, Moodie, Seewald, Bartlett, & Scollie, 2011; Moodie, Bagatto et al., 2011; Moodie, Kothari et al., 2011). Two projects (Chapters 3 and 4) included the participation of The Network of Pediatric Audiologists of Canada. The outcome measures guideline to evaluate the auditory development and performance of young children who wear hearing aids is called The University of Western Ontario Pediatric Audiological Monitoring Protocol (UWO PedAMP). This body of work includes a chapter on knowledge translation and how it can be used to promote the clinical implementation of evidence in audiology (Chapter 3). It also includes three studies: (1) an examination of factors influencing the use of evidence by Canadian audiologists [Chapter 2]; (2) an initial evaluation by the Network of Pediatric Audiologists of Canada of the individual components considered for inclusion in the UWO PedAMP [Chapter 4]; and (3) a final evaluation by the Network audiologists of the released version of the UWO PedAMP and associated training materials [Chapter 5]. Results of the first study indicated that Canadian audiologists rate themselves as competent in finding, evaluating and using research evidence to change practice. Their greatest barriers to evidence-based practice are related to time. By partnering with Canadian audiologists and using the knowledge-to-action framework to guide us (Chapter 4), we were successful in developing the UWO PedAMP guideline into what they rated as being a high-quality, systematic, hearing aid outcome evaluation tool that improves the quality and effectiveness of audiological care received by young children with hearing loss. The results presented in Chapter 5 indicated that the UWO PedAMP is appropriate for clinical implementation, and is recommended by these Canadian audiologists as preferred audiology practice

A Comparative Analysis of the Mechanisms of Social Inclusion for Hard of Hearing People in Germany and in the Russian Federation

Inklusion von Menschen mit Behinderungen ist zu einem der vordringlichen Ziele der Sozialpolitik der Europäischen Union und in der Russischen Föderation geworden, u. a. aufgrund der zunehmenden Zahl von Ländern, die die UN-BRK1 ratifizierten, sowie Herausforderungen wegen, die eine "alternde" Gesellschaft verursacht. Jedoch werden Menschen mit Hörbehinderung und deren spezielle Bedürfnisse im Vergleich zu anderen, eher sichtbaren Behinderungen, oft übersehen. Das zentrale Anliegen der vorliegenden Untersuchung ist es, die Mechanismen und Ergebnisse der sozialen Inklusion schwerhöriger Menschen in Russland und Deutschland näher zu betrachten und zu vergleichen, sowie mit empirisch belegten Befunden zur Forschung über schwerhörige Personen beizutragen. Der Forschungstand hierzu ist in den Disability Studies noch sehr lückenhaft. Eine Analyse der Sozial- und Behindertenpolitik in beiden Ländern sowie ein Vergleich der rechtlichen und institutionellen Maßnahmen als auch der Chancen bildet den Rahmen für eine empirische Analyse (Fragebogen, Interviews mit schwerhörigen Personen, NGOs und Experten). Die Einschätzung der politischen Maßnahmen und der Infrastrukturen folgt den konzeptionellen und normativen Bewertungsmaßstäben der Disability Studies. Die vergleichende Analyse konzentriert sich auf den Zugang schwerhöriger Menschen zu Bildung und Arbeitsmarkt, zu Wiedereingliederung, Information und Kommunikation – Bereiche welche für Inklusion und Teilhabe entscheidend sind. Die empirischen Erhebungen enthalten explorative, nicht-repräsentative Fragebögen-Untersuchungen unter a) 190 jungen Befragten, 18-35 Jahre alt (davon 136 aus Deutschland; 150 aus Russland) b) 110 älteren Befragten, 65 bzw. 60 Jahre alt — abhängig vom betreffenden Land — und älter (43 aus Deutschland; 67 aus Russland) und Experten-Interviews mit Schlüsselpersonen zum Thema (Forscher, politische Entscheidungsträger, medizinische und pädagogische Experten, schwerhörige NGO-Aktivisten); darüber hinaus Leitfaden-Interviews mit schwerhörigen Personen (11 in Deutschland, 16 in Russland). Übereinstimmungen und Abweichungen in den nationalen politischen Richtlinien werden diskutiert, Beispiele von positiven Praktiken in medizinischer, ausbildungsbezogener und beruflicher Rehabilitation und potentielle politische Maßnahmen werden vorgeschlagen.Inclusion of people with disabilities has become one of the priorities of the social policy in the European Union and in the Russian Federation, in part, in connection with the increasing ratification of the UN CRPD worldwide and problems induced by the “ageing” society. However, people with hearing loss and their specific needs are often overlooked in comparison with more visible disabilities. The main purpose of this study is to look into and compare the mechanisms and results of social inclusion of hard of hearing people (HoH) in Russia and Germany and to contribute with empirically grounded findings to the research on hard of hearing people of which there is a lack in the disability research field. An analysis of the social and disability related policies in both countries and a comparison of the legal and institutional arrangements and opportunities provides the framework for the empirical analysis (questionnaire, interviews with HoH persons, NGOs and with experts). The appraisal of the policies and infrastructures is following the conceptual and normative benchmarks of the Disability studies. The comparative analysis is focused on access of HoH people to education and employment, to rehabilitation, information and communication – the fields critical to inclusion and participation. The empirical research comprises an explorative non-representative questionnaire survey with a) 190 young respondents aged 18-35 years (136 from Germany, 150 from Russia) b) 110 elderly respondents (65 or 60 years old and older; 43 from Germany, 67 from Russia), and expert interviews with the key persons in the field (researchers, political decision-makers, medical and educational professionals, hard of hearing NGO activists); furthermore, guided interviews with HoH people (N=11 in Germany, N=16 in Russia) were conducted. Commonalities and discrepancies in the national policy directions are discussed, examples of positive practices in medical, educational and professional rehabilitation and potential policy measures are suggested

Consensus Statement on Bone Conduction Devices and Active Middle Ear Implants in Conductive and Mixed Hearing Loss

Nowadays, several options are available to treat patients with conductive or mixed hearing loss. Whenever surgical intervention is not possible or contra-indicated, and amplification by a conventional hearing device (e.g., behind-the-ear device) is not feasible, then implantable hearing devices are an indispensable next option. Implantable bone-conduction devices and middle-ear implants have advantages but also limitations concerning complexity/invasiveness of the surgery, medical complications, and effectiveness. To counsel the patient, the clinician should have a good overview of the options with regard to safety and reliability as well as unequivocal technical performance data. The present consensus document is the outcome of an extensive iterative process including ENT specialists, audiologists, health-policy scientists, and representatives/technicians of the main companies in this field. This document should provide a first framework for procedures and technical characterization to enhance effective communication between these stakeholders, improving health care
