Tools for telehealth: A correlational analysis of app-based hearing testing

Objective

Telehealth evaluation of hearing is rapidly evolving; however, the lack of consensus on the most accurate remote hearing test application has made hearing evaluation complicated. The objective of this study was to evaluate the correlation between the pure tone audiometry results obtained from app-based hearing testing programs and a traditional audiogram.

Methods

A prospective within-subject and between-subject study design was used to correlate audiogram results between app-based hearing programs and a traditional audiogram. All participants completed a traditional audiogram, 1 commercial app-based test (ShoeBox), 2 consumer app-based tests (EarTrumpet and Hearing Test and Ear Age Test [HTEAT]), and a Hearing Handicap Inventory screening version (HHI-S). Testing was conducted in an acoustically controlled environment (traditional) and a quiet room (app-based hearing tests).

Results

A total of 39 participants were enrolled in the study (21 with normal hearing and 18 with hearing loss). In patients with normal hearing, only the commercial hearing testing app (ShoeBox) had a statistically significant pure tone average correlation in both ears with traditional audiometry (Right ear-r = 0.7, p = .005, Left ear-r = 0.66, p = .001). Both consumer and commercial apps had statistically significant correlations with both ears in patients with hearing loss (ranging from r = 0.62 to r = 0.9). Regarding accuracy within 10 dB of the pure tone average of the traditional audiogram of all tested ears, the commercial app-based test was accurate in 94% for all ears (normal and hearing loss), while consumer app-based tests were between 14% and 36% for all ears. The HHI-S indicated no hearing impairment in 95% of those with normal hearing and indicated hearing impairment in 89% of those with hearing loss.

Conclusion

Commercial-grade app-based pure tone audiometry demonstrates overall strong correlation and accuracy with traditional audiometry. The HHI-S assessment remains a valid and useful tool to predict normal hearing and hearing impairment.

Personal experience with the remote check telehealth in cochlear implant users: from COVID-19 emergency to routine service

PURPOSE

To critically illustrate the personal experience with using the "Remote Check" application which remotely monitors the hearing rehabilitation level of cochlear implant users at home and further allows clinicians to schedule in-clinic sessions according to the patients' needs.

METHODS

12-month prospective study. Eighty adult cochlear implant users (females n = 37, males n = 43; age range 20-77 years) with ≥ 36 months of cochlear implant experience and ≥ 12 months of stable auditory and speech recognition level volunteered for this 12-month long prospective study. For each patient, at the beginning of the study during the in-clinic session to assess the stable aided hearing thresholds and the cochlear implant integrity and patient's usage, the "Remote Check" assessment baseline values were obtained. "Remote Check" outcomes were collected at different times in the subsequent at-home sessions, to identify the patients that had to reach the Center. Chi-square test has been used for statistical analysis of the comparison of the "Remote Check" outcomes and in-clinic session results.

RESULTS

"Remote Check" application outcomes demonstrated minimal or no differences between all sessions. The at-home Remote Check application reached the same clinical outcomes as the in-clinic sessions in 79 out 80 of participants (99%) with high statistical significance (p < 0.05).

CONCLUSIONS

"Remote Check" application supported hearing monitoring in cochlear implant users that were not able to attend the in-clinic review during COVID-19 pandemic time. This study demonstrates that the application can be a useful routine tool also for clinical follow-up of cochlear implant users with stable aided hearing.

AMTASTM and user-operated smartphone research application audiometry-An evaluation study

OBJECTIVE

To evaluate two user-operated audiometry methods, the AMTASTM PC-based audiometry and a low-cost smartphone audiometry research application (R-App).

DESIGN

A repeated-measures within-subject study design was used to compare both user-operated methods to traditional manual audiometry and to evaluate test-retest reliability of each method.

STUDY SAMPLE

58 subjects were recruited in the study of which 83 ears had normal hearing thresholds and 33 ears had hearing loss (pure-tone average > 25 dB HL). Average age of participants was 44.8 years, with an age range of 11-85.

RESULTS

Standard deviation of absolute differences ranged between 3.9-6.9 dB on AMTASTM and 4.5-6.8 dB on the R-App. The highest variability was found at the 8000 Hz frequency (R-App and AMTASTM test) and 3000 Hz frequency (AMTASTM retest). Evaluation of test-retest reliability of AMTASTM and R-App showed SD of absolute differences ranging between 3.5-5.8 dB and 3.1-5.0 dB, respectively. The mean threshold difference between test and retest was within ±1.5 dB on AMTASTM and ±1 dB on the R-App.

CONCLUSION

Accuracy of AMTASTM and the R-App was within acceptable limits for audiometry and comparable to traditional manual audiometry on all tested frequencies (250-8000 Hz). Evaluation of test-retest reliability showed acceptable variation on both AMTASTM and R-App. Both user-operated methods could be reliably performed in a quiet non-soundproofed environment.

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.

Impact of COVID-19 pandemic on audiology practice: A scoping review

Background

COVID-19 has significantly impacted the professional practice of health care professionals including audiological practice. Audiologists had to adopt to changes and modify their practice to deal with the pandemic. Reasonable published work has been seen since the onset of the pandemic, depicting impact on the audiology practice across the globe in different practice settings and contexts. The present scoping review was carried out to explore the impact of COVID-19 pandemic on audiology practice and the challenges faced.

Material & methods

A literature search was carried out to identify the studies exploring the impact of COVID-19 pandemic on audiology practice. Three electronic databases namely Scopus, PubMed/Medline, and Cochrane Library were searched using keywords. After title and abstract screening, suitable studies were identified.

Results

Of the total 172, nine studies focusing on impact of COVID-19 pandemic on audiology practice COVID-19, published between January 2020 to June 2021 were included. Overall, the COVID-19 pandemic and the subsequent restrictions, caused changes in routine clinical practices in audiology. These changes were with respect to stringent infection control measures, mode of service delivery, changes in routines with reduced services or prioritizing services. Challenges included issues with remote services, experience, and support.

Conclusion

The present review reveals the changes in audiology practice during COVID –19 and challenges encountered by audiologists. These findings would help in better planning of audiology practice in the post pandemic world.

Guidelines of the French Society of Otorhinolaryngology (SFORL) for teleconsultation in patients with vertigo during the COVID-19 pandemic

OBJECTIVES

In the context of the SARS-CoV-2 pandemic, patients may have been dissuaded from seeking consultation, thus exposing themselves to a risk of loss of chance. This guide aims to define how teleconsultation can assist in assessing vertiginous adults or children, and to gather the information needed to provide quick medical care.

METHODS

These recommendations rely on the authors' experience as well as on literature. A survey on otoneurologic approach via telemedicine has been conducted based on a literature search until March 2020.

RESULTS

The first clinical assessment of the vertiginous patient via teleconsultation can only be successful if the following conditions are met: initial contact to verify the feasibility of the assessment at a distance, the presence of a caregiver in order to assist the patient, the possibility of making video recordings. Medical history via telemedicine, as in a face-to-face assessment, allows to assess the characteristics, duration, frequency, and potential triggering factors of the vertigo, in both children and adults. During teleconsultation, the following tests can be carried out: oculomotricity evaluation, assessment of balance, simple neurological tests, checking for positional vertigo/nystagmus and, eventually to perform canalith-repositioning procedures. In children, the following should be searched for: history of hearing or visual impairment, a context of fever or trauma, otorrhea, signs of meningeal irritation.

CONCLUSION

The neurotologic telemedicine relies on the accuracy of the clinical assessment, which is based on history taking and a few simple tests, encouraging the development of a decision-making algorithm adapted for teleconsultation. However, the latter has its limitations during an emergency examination of a new patient presenting vertigo, and, at least in some cases, cannot replace a face-to-face consultation. Teleconsultation is often adapted for follow-up consultations of previously selected vertiginous patients during face-to-face assessment.

[Patient satisfaction after mandibular orthosis fitting by teleconsultation]

INTRODUCTION

Since the COVID-19 crisis, we have all had to apply telemedicine. As an example, we offered patients teleconsultations for titration of their mandibular advancement device for sleep apnea. The main objective of this study was to determine patient satisfaction with this new method of consultation.

METHODS

A cross-sectional survey using a satisfaction questionnaire was carried out in patients having been given an appliance adjustment teleconsultation by our establishment between March 2020 and February 2021.

RESULTS

Adjustment of their orthosis by telemedicine was systematically proposed to seventy-five patients, of whom seventeen accepted (22.7%), with a mean age of 52.3 years. The consultations were short (mean duration: 5min), and more than a third were carried out at the patient's workplace; by and large, they were considered highly satisfactory (mean score 4.3/5).

CONCLUSION

Although appliance adjustment by teleconsultation was not overwhelmingly accepted when offered, it gave great satisfaction after performance. This type of consultation is both technologically and administratively easy to organize, and it can be proposed as a supplementary service, suitable for all ages.

Ear, Nose, and Throat Practice Guidelines: An Update for COVID-19

Introduction  Amidst another wave of COVID-19, the alarming number of cases per day in India has affected the healthcare system and professionals tremendously. As the disease burden continues to increase, ear, nose, and throat (ENT) specialists remain at high risk of exposure to this aerosol borne virus. This requires the creation and regulation of protocols for conducting routine clinical practice, especially by ENT specialists.

Objectives  To review the available literature and to propose strategies and recommendations for ENT practitioners to conduct their regular practice amidst this pandemic.

Data synthesis  A systematic review of the available literature on ENT practice during the COVID-19 pandemic was done. Out of the many protocols proposed in various studies, the most practical and feasible ones that could be adopted by practicing ENT doctors/ surgeons in the long run were selected. Adequate precautions and use of high level of personal protective equipment (PPE) is required to be adopted by all practicing ENT doctors. Use of teleconsultation has been promoted as it limits face-to-face exposure. Proper guidelines should be followed for both emergency and elective surgeries. Endoscopy can be used as a safe and useful tool for ENT examination.

Conclusion  As practicing otorhinolaryngologists, it is of utmost importance that we take all necessary precautions and adopt safety measures in our clinical practice while conducting out patient department (OPD) consultations, operative procedures, and emergency care to protect our patients, ourselves, and other healthcare staff during this time.

The Impact of COVID-19 on Individuals with Hearing and Visual Disabilities during the First Pandemic Wave in Italy

BACKGROUND

The COVID-19 pandemic has imposed radical behavioral and social changes in the general population, significantly impacting the lives of individuals affected by disabilities. The aim of this study was to investigate the impact of COVID-19 on non-institutionalized subjects with sensorineural disabilities during the first COVID-19 wave in Italy.

METHODS

A 39-item online national survey was disseminated from 1 April 2020 to 31 June 2020 via social media throughout Italy to communities of individuals with proven severe sensorineural disabilities, affiliated to five national patient associations. The survey collected extensive information on the socio-demographic profile, health, everyday activities, and lifestyle of individuals with hearing and visual disabilities.

RESULTS

One hundred and sixty-three respondents with hearing (66.9%) and visual (33.1%) disabilities returned a usable questionnaire. The mean age of interviewees was 38.4 ± 20.2 years and 56.3% of them were females. Despite the vast majority of respondents (77.9%) perceiving their health status as unchanged (68.8% of interviewees with hearing deficits vs. 96.3% of those with visual impairments), about half the interviewees reported sleep disorders during lock-down, more likely those with visual deficits. Remote services were seemingly more effective for business than school activities. Furthermore, although just 18.8% of respondents rated remote rehabilitation care unsatisfactory, only 12.8% of interviewees felt supported by health and social services during the COVID-19 emergency. The vast majority of respondents were concerned about the future and the risk of SARS-CoV-2 contagion, particularly individuals with hearing impairments. Among the various risk mitigation measures, facemasks caused the greatest discomfort due to communication barriers, particularly among interviewees affected by hearing disabilities (92.2% vs. 45.7%). The most common request (46.5%) of respondents to reduce the inconveniences of the COVID-19 emergency country lock-down was improving the access to and delivery of health and social services for individuals with sensorineural disabilities (19.3%), followed by the use of transparent masks (17.5%).

CONCLUSIONS

Although health protection measures such as face masks and social distancing play a key role in preventing and controlling the spread of SARS-CoV-2, the unmet needs of disabled individuals should be carefully considered, especially those affected by sensory disabilities. Tailored access to health and social services for individuals affected by sensorineural disabilities should be implemented. Additional actions should include the use of to face masks to reduce communication barriers linked to hearing-impairment, as well as the improvement of remote services, especially distance learning at school.

The impact of COVID-19 on provision of UK audiology services & on attitudes towards delivery of telehealth services

OBJECTIVE

To (i) identify the impact of COVID-19 on provision of UK audiology services across sectors (ii) compare teleaudiology service provision between private and public sectors before and after the introduction of restrictions and (iii) identify barriers to teleaudiology delivery amongst UK hearing care professionals in both sectors.

DESIGN

A mixed-methods cross-sectional survey study design. Responses to the structured questionnaire were analysed using descriptive and non-parametric statistics.

STUDY SAMPLE

UK based hearing care professionals (HCP) (n = 323) completed the survey (218 public sector; 89 private sector).

RESULTS

Changes in working patterns varied greatly between different sectors, with 61% of national employed and 26% of independent HCPs being furloughed, compared with 1% in the public sector. Use of telehealth was under-utilised across all sectors and groups in UK hearing healthcare, despite 92% of public and 75% of private HCPs reporting feeling comfortable conducting remote consultations.

CONCLUSION

This study highlights a variation in teleaudiology adoption and key barriers across sector in the UK. A collaborative approach between hearing device manufacturers, research centres, HCPs and professional bodies is required for the creation of targeted guidance and training materials according to sector, to support clinicians in effective teleaudiology provision.

Training outcomes for audiology students using virtual reality or traditional training methods

Due to limited space and resources, it can be difficult to train students on audiological procedures adequately. In the present study, we compared audiology training outcomes between a traditional approach and a recently developed immersive virtual reality (VR) approach in audiology students. Twenty-nine first-year audiology students participated in the study; 14 received traditional training (“TT group”), and 15 received the VR training (“VRT group”). Pre- and post-training evaluation included a 20-item test developed by an audiology educator. Post-training satisfaction and self-confidence were evaluated using Likert scales. Mean post-training test scores improved by 6.9±9.8 percentage points in the TT group and by 21.1±7.8 points in the VRT group; the improvement in scores was significant for both groups. After completing the traditional training, the TT group was subsequently trained with the VR system, after which mean scores further improved by 7.5 points; there was no significant difference in post-VR training scores between the TT and VRT groups. After training, the TT and VRT groups completed satisfaction and self-confidence questionnaires. Satisfaction and self-confidence ratings were significantly higher for the VR training group, compared to the traditional training group. Satisfaction ratings were “good” (4 on Likert scale) for 74% of the TT group and 100% of the VRT group. Self-confidence ratings were “good” for 71% of the TT group and 92% of the VRT group. These results suggest that a VR training approach may be an effective alternative or supplement to traditional training for audiology students.

Best practice recommendations: ENT consultations during the COVID-19 pandemic

These best practice recommendations for ENT consultations during the COVID-19 pandemic have been drawn up because ENT examinations and treatments are at risk of contamination by the SARS-Cov-2 virus in certain instances. Thus, ENT specialists are among the professionals who are most exposed to this infection. During the pandemic, insofar as an asymptomatic patient may be infected and contagious, the same precautions must be employed whether the patient is ill with, suspected of having, or without any clinical evidence of COVID-19 infection. According to the scientific data available, the examinations and procedures potentially exposing to projections/aerosolizations of organic material of human origin are considered to be at risk of staff contamination. For ENT examinations and procedures without exposure to such projections/aerosolizations, the professional is advised to a long sleeve clean outfit, a surgical mask and gloves in case of contact with the patient's mucosa. ENT examinations and procedures with exposure to these projections/aerosolizations require the so-called "airborne", "contact", and "droplets" additional precautions: FFP2/N95 respiratory protection device, eye protection, disposable headwear and long sleeve overgown.

Conseils de bonnes pratiques : consultation d’ORL en contexte épidémique COVID-19

Ces conseils de bonnes pratiques sur la consultation en ORL en contexte épidémique COVID-19 ont été rédigés car l’examen et les soins ORL sont dans certaines situations à risque de contamination par le virus SARS-CoV-2. Ainsi, les spécialistes ORL comptent parmi les professionnels les plus exposés à cette infection. En contexte épidémique, dans la mesure où un patient asymptomatique peut être infectant, il est proposé de respecter les mêmes précautions que le patient soit atteint, suspect ou sans évidence clinique d’infection COVID-19. En fonction des données scientifiques à disposition, les examens et actes exposant potentiellement à des projections/aérosolisations de produits biologiques d’origine humaine sont considérés comme à risque de contamination du personnel. Pour les soins ORL sans exposition à de telles projections/aérosolisations, le professionnel porte une tenue à manches longues, un masque chirurgical et des gants à usage unique en cas de contact avec les muqueuses. Pour les soins ORL exposant à ces projections/aérosolisations, leur réalisation nécessite des précautions additionnelles dites complémentaires de type « contact », « gouttelettes » et « air » et « gouttelettes » : appareil de protection respiratoire de type FFP2, protection oculaire, gants à usage unique systématiques, charlotte, surblouse à manches longues.
