Tele-audiology diagnostic testing services for children with disabilities in a school setting: A pilot study.

OBJECTIVE: Children with disabilities (CWDs) having comorbidities face challenges in accessing and completing diagnostic hearing evaluations. This study was conducted to determine whether a tele-audiology diagnostic test battery can be administered to school-aged CWDs having comorbidities in a school-setting. DESIGN: A proof-of-concept pilot study using a cross-sectional design. STUDY SAMPLE: Ten typically developing children between 3 years 9 months and 10 years 9 months of age; mean age of 8 years 3 months (pilot-norm group) and seven CWDs having comorbidities between 3 years and 8 years and 1 month of age; mean age of 5 years and 2 months (CWD group) participated in the study. A diagnostic test protocol delivered via tele-audiology was first administered to the pilot-norm group to ensure its efficiency and suitability for use in the CWD group. Following modifications, the diagnostic test protocol was delivered for CWDs. RESULTS: We identified key aspects, including the role of the facilitator in conducting a diagnostic test battery using tele-audiology on CWDs, the usefulness of having co-facilitators to support child-friendly testing, as well as technology-related requirements. With respect to tele-audiology diagnostic testing, it was possible to quickly assess peripheral hearing using synchronous tele video-otoscopy, tympanometry, and DPOAEs. We identified limitations in conducting behavioral audiometry and completing tone-burst ABRs in CWDs. CONCLUSION: Evidence was obtained from this exploratory pilot study that a tele-audiology diagnostic test battery can be administered in a school setting to school-aged CWDs having comorbidities. Tele-audiology can be considered to provide hearing healthcare services to school-aged CWDs who may otherwise not receive these services.

Telehealth solutions for assessing auditory outcomes related to noise and ototoxic exposures in clinic and research.

Nearly 1.5 billion people globally have some decline in hearing ability throughout their lifetime. Many causes for hearing loss are preventable, such as that from exposure to noise and chemicals. According to the World Health Organization, nearly 50% of individuals 12-25 years old are at risk of hearing loss due to recreational noise exposure. In the occupational setting, an estimated 16% of disabling hearing loss is related to occupational noise exposure, highest in developing countries. Ototoxicity is another cause of acquired hearing loss. Audiologic assessment is essential for monitoring hearing health and for the diagnosis and management of hearing loss and related disorders (e.g., tinnitus). However, 44% of the world's population is considered rural and, consequently, lacks access to quality hearing healthcare. Therefore, serving individuals living in rural and under-resourced areas requires creative solutions. Conducting hearing assessments via telehealth is one such solution. Telehealth can be used in a variety of contexts, including noise and ototoxic exposure monitoring, field testing in rural and low-resource settings, and evaluating auditory outcomes in large-scale clinical trials. This overview summarizes current telehealth applications and practices for the audiometric assessment, identification, and monitoring of hearing loss.

School-based language screening among primary school children using telepractice: A feasibility study from India.

Purpose: This study explored the feasibility of conducting school-based language screening using telepractice to expand its scope for providing speech-language pathology services in India. Method: Thirty-two primary school children underwent language screenings through in-person and telemethods. Screening through telemethod was conducted by a Speech-Language Pathologist (SLP) using digitised picture stimuli presented through videoconferencing and remote computing with assistance of a facilitator at school site. Technology and child-related factors influencing screening were documented using an inventory. Result: Language outcomes through in-person and telemethods revealed no significant differences in both receptive and expressive domains, suggesting absence of bias due to testing method used. Use of multiple internet options at both sites helped overcome technical challenges related to connectivity during screening through telemethod. The trained facilitator played a crucial role in overcoming child related factors such as poor speech intelligibility, poor audibility of voice, motivation, interaction with SLP and need for frequent breaks. Conclusion: Feasibility of conducting school-based language screening using multiple internet options and help of a facilitator at school demonstrates promise for delivery of services by SLP in resource constrained contexts such as India.

School entry level tele-hearing screening in a town in South India - Lessons learnt.

INTRODUCTION: School screening is warranted in developing countries that do not have newborn hearing screening as schools provide access to a large number of young children between 3 and 5 years of age. Due to scarcity of technical manpower and equipment, hearing screening programs are not often conducted in developing countries. In these circumstances, telehealth services appear to be a reasonable solution. Consequently, the purpose of this study was to assess the feasibility of school hearing screening using telehealth technology operated by a practitioner located 400 kms away at a distant hospital. METHOD: Thirty one children received hearing screening procedures in their school. Each child was screened for both in-person and telehealth conditions to assess screening results. Remote computing software was employed for the telehealth condition in order for the practitioner to remotely operate an audiometer, DPOAE system and a video otoscope interfaced to a personal computer at the school site.Teamviewer version 10 was used to provide encrypted videoconferencing and synchronous hearing screening services between the hospital and school sites. All screening was conducted using a mobile phone hotspot or dongle device based internet connection to insure reliable connectivity. RESULTS: The outcome revealed no significant difference between PTA and DPOAE performed in-person and tele-hearing screening methods. Concurrence of greater than 87% was achieved between in-person and tele-video-otoscopy. Strengths and challenges were documented for tele-hearing screening in three different dimensions: technical issues, child related and school related. Understanding these challenges may provide more effective tele-audiology services. DISCUSSION: The results of the study indicate synchronous hearing screening services can be provided in a school setting using mobile hotspot or dongle connectivity in locations where Internet bandwidth is otherwise restricted.

Teleaudiology.

Teleaudiology has become a more viable approach to delivering care. Asynchronous and synchronous delivery can be used to deliver Teleaudiology. Hybrid delivery involves using both synchronous and asynchronous modes of delivery. Teleaudiology has been used for otoscopy, audiometry, immitance, cochlear implant programming and newborn screening. Teleaudiology is a viable technology, although reimbursement remains unclear.

Improving the access of young urban children to speech, language and hearing screening via telehealth.

We studied the feasibility of low-cost videoconferencing (using Skype) in urban community health clinics for speech, language and hearing screening of children up to six years of age. During a two-year study, screening services were provided via videoconferencing at two community clinics in an inner city area of Cleveland, Ohio. In total, 411 screenings were completed. Of these, 358 children (87%) received hearing screenings, 377 (92%) received tympanometry screening and 263 (64%) received speech and language screening only. A total of 151 children were aged three years or under (37%). The reliability of pure tone hearing screening (n = 7), DPOAE screening (n = 51) and speech-language screening (n = 10) was 100%. Typanometry screenings (n = 55) were 84% reliable. Families reported a high level of satisfaction with both the technology and with the videoconferencing. The results indicate that low-cost videoconferencing for screening of speech, language and hearing development in very young children in urban community health clinics is feasible, reliable and strongly supported by the community.

Telehealth in audiology: the need and potential to reach underserved communities.

Permanent hearing loss is a leading global health care burden, with 1 in 10 people affected to a mild or greater degree. A shortage of trained healthcare professionals and associated infrastructure and resource limitations mean that hearing health services are unavailable to the majority of the world population. Utilizing information and communication technology in hearing health care, or tele-audiology, combined with automation offer unique opportunities for improved clinical care, widespread access to services, and more cost-effective and sustainable hearing health care. Tele-audiology demonstrates significant potential in areas such as education and training of hearing health care professionals, paraprofessionals, parents, and adults with hearing disorders; screening for auditory disorders; diagnosis of hearing loss; and intervention services. Global connectivity is rapidly growing with increasingly widespread distribution into underserved communities where audiological services may be facilitated through telehealth models. Although many questions related to aspects such as quality control, licensure, jurisdictional responsibility, certification and reimbursement still need to be addressed; no alternative strategy can currently offer the same potential reach for impacting the global burden of hearing loss in the near and foreseeable future.

Remote hearing screenings via telehealth in a rural elementary school.

PURPOSE: Telehealth (telepractice) is the provision of health care services using telecommunications. Telehealth technology typically has been employed to increase the level of health care access for consumers living in rural communities. In this way, audiologists can use telehealth to provide services in the rural school systems. This is important because school hearing screening programs are the foundation of educational audiology programs. Therefore, the goal of this study was to determine the feasibility of providing hearing screening services by telehealth technology to school-age children. METHOD: Hearing screening services-including otoscopy, pure-tone, and immittance audiometry-were conducted on 32 children in 3rd grade attending an elementary school in rural Utah. Each child received 1 screening on-site and another through telehealth procedures. RESULTS: Immittance and otoscopy results were identical for on-site and telehealth screening protocols. Five children responded differently to pure-tone stimuli presented by the telehealth protocol than by the on-site protocol. However, no statistically significant difference was found for pure-tone screening results obtained by telehealth or on-site screening procedures (binomial test, p = .37). Likewise, overall screening results obtained by traditional and telehealth procedures were not statistically significant (binomial test, p = .37). CONCLUSION: The results of this study suggest that school hearing screenings may be provided using telehealth technology. This study did find that 5 students performed differently to pure-tone screenings administered by the telehealth protocol in contrast to on-site hearing screening services. Further research is necessary to identify factors leading to false responses to pure-tone hearing screening when telehealth technology is used. In addition, telehealth hearing screening protocols should be conducted with participants of different age groups and experiencing a wide range of hearing loss to further clarify the value of telehealth technology.

Telemedicine for audiology screening of infants.

Distortion product otoacoustic emissions (DPOAE) and automated auditory brainstem response (AABR) screening were conducted in infants at a distant hospital using remote computing. Eighteen males and twelve females ranging in age from 11-45 days were tested. Both DPOAE and AABR data were recorded using an integrated test system which was connected to the computer network at the Utah Valley Regional Medical Center. Using a broadband Internet connection, an examiner at Utah State University, 200 km away, could control the DPOAE and the ABR equipment. Identical hearing screening results were obtained for face-to-face and telemedicine trials with all infants. The DPOAE means for face-to-face and telemedicine trials were not significantly different at any frequency. In an analysis of variance, there was no significant difference for the test method (F = 0.8, P > 0.05). These results indicate that remote computing is a feasible telemedicine method for providing DPOAE and ABR hearing screening services to infants in rural communities.

Providing basic hearing tests using remote computing technology.

We administered pure tone and otoacoustic emissions testing to subjects in a distant community using remote computing technology. Fifteen men and 15 women ranging in age from 18-30 years were tested. An audiometer was used to measure subject pure tone thresholds. In addition, distortion product otoacoustic emissions (DPOAEs) data were recorded using a portable system. Both systems were interfaced to a PC which was connected to the local area network at Minot State University (MSU). An examiner at Utah State University, 1100 km away, could control both the DPOAE and the audiometer equipment at MSU. Overall, the pure tone means for the face-to-face and telemedicine trials were equivalent at each frequency. Moreover, DPOAE recordings exhibited equivalent results at each frequency for telemedicine and face-to-face trials. These results support the use of remote computing as a telemedicine method for providing pure tone audiometry and DPOAE testing to distant communities.

Audiology telemedicine.

Various real-time telemedicine applications have been investigated in audiology, including pure tone audiometry, otoacoustic emission testing, auditory brainstem response recordings, hearing aid fitting and video-otoscopy. Store-and-forward applications have usually been used to transmit basic patient data including case history information and hearing screening results, although both video-nystagmography and video-otoscopy have been piloted. Remote access to computerized equipment is relevant to audiology telemedicine, although there have been few reports of the use of application sharing using computerized audiology equipment. In a pilot trial of real-time telemedicine, both pure tone and speech audiometry measures were provided remotely through application sharing. Audiology telemedicine appears promising, but it is at an early stage of development and many areas such as its cost effectiveness, patient acceptance and test efficacy require systematic investigation.
