Development and Evaluation of Portal do Zumbido : A Novel Telehealth Approach to Tinnitus

Abstract

Introduction  Tinnitus is a prevalent symptom in audiological clinics, and the speech therapist participates in the assessment, diagnosis, and intervention of tinnitus. A range of studies have been developed with the aim to promote auditory health, and telehealth is an option for this purpose.

Objective  The aim of the present study was to develop and assess a virtual platform for tinnitus management for speech therapists.

Methods  The present study provided a distance-learning-course, with the aid of Portal do Zumbido , available in the following electronic address: zumbido.fob.usp.br. Infographics were available for download, and modules were made to comprise the introduction to the symptoms, assessment, and intervention for tinnitus.

Results  Speech therapists of different regions of Brazil received an e-mail invitation to participate and to assess the platform, 46 of whom registered. From the 46 speech therapists registered, 38 assessed the virtual platform with the aid of a questionnaire about the theoretical content and then answered a motivational research sheet (MRS). The speech therapists correctly answered 90% and 100% of the questions in the questionnaire and in the MRS, respectively, which may indicate that the professionals positively absorbed the content; thus, the content was considered to be impressive when the MRS was analyzed.

Conclusion   Portal do Zumbido was developed and is available for access in the following electronic address: zumbido.fob.usp.br. Furthermore, the platform received a positive assessment by the speech therapists who participated in the present study.

Introduction

Tinnitus is a symptom characterized as the perception of a sound in the ears or in the head without an external sound stimulus. It can occur unilaterally or bilaterally and classification varies according to the duration, so that it is classified as acute when it occurs for less than 6 months, or chronic when it occurs for 6 months or longer. The prevalence of the symptom is 10 to 15%, and it is higher among the elderly. ¹

This auditory complaint can be associated with quality of life impairments, such as decreased social interaction, insomnia, emotional and general health changes as well as problems at work. ² Furthermore, tinnitus management can attach a high cost to health services because it is not standardized. ^{3 4}

The subjects with tinnitus complaints often search for hearing health services, and this has generated a growing search for the evaluation, diagnosis, and effective treatment of the symptom. Thus, recent studies have been developed with the aim of helping professionals who attend patients with tinnitus at their clinics for symptom management. ^{5 6}

The etiological diagnosis is important, and, due to the multifactorial etiology of tinnitus, an audiologist is required from the assessment to the intervention of the symptom. ^{7 8} Due to this concern, several studies have been developed with the purpose of hearing health promotion. However, there is an irregular and insufficient distribution of public health services, educational institutions and qualified professionals, leading to the difficulties of access to specialized services. Due to the current condition, telehealth can be a significant alternative at this time. ⁹

In the context of an irregular distribution of health professionals, shortage of services that promote the training of professionals in this area, and current technological advances, telehealth emerges as an important alternative for the use of teleassistance resources (health care alternatives) and tele-education (distance education), since it allows the reduction of costs and resources needed, as well as facilitates the quickly professional–patient relationship. ^{10 11}

Telehealth is the transferring of health information between distant places, and it includes a range of activities beyond patient care, such as health promotion, epidemiological surveillance, disease prevention, patient and professional education, and health service management. ⁹ Systematic actions are required to plan and develop new teaching strategies and methods that incorporate the teaching-learning process into information and communication technologies, especially the internet. ¹²

Due to the wide geographic dimensions of Brazil, there is a heterogeneity in the distribution of speech therapists. Thus, telehealth is an option for the specialized knowledge decentralization of health professionals. ¹³ Therefore, the present study aims to develop and assess a virtual platform on tinnitus management to provide scientific technical access for speech therapists.

Materials and Methods

The study was developed in the Speech Therapy Program at Faculdade de Odontologia de Bauru - Universidade de São Paulo, with the approval of the Research Ethics Committee (CEP) of this institution (number 88446218.2.0000.5417).

Development of a Virtual Learning Platform

A proposal was made to conduct the distance-learning course (tele-education) through the internet, using a virtual management platform of tinnitus in subjects with and without hearing impairment entitled “Portal do Zumbido” , which is available at the following electronic address: zumbido.fob.usp.br. It is important to note that although the platform was initially designed to provide necessary information to professionals who attend patients with auditory impairments (tinnitus/hearing loss), it can be accessed by any professional who has interest to require information about the symptom, diagnosis, evaluation, and treatment.

To incorporate real teaching-learning situations and use the potential of the internet, the development of the content of the platform used information design and infographicsas facilitating resources.

Information design is a facilitating agent in the selection, structuring, and information organization of complex systems. ¹⁴ Together with web design, it provides information that the interpreter needs for specific tasks based on the interaction between verbal and visual communication. Information design is based on helping people with different experiences. ¹⁵

The infographics, in turn, were used as tools for visual representations of informational character, since they have a high power of attraction, combining text and image to reveal more clearly and simplify complex information, saving space. ^{16 17}

Content Covered in the Virtual Platform

The main contents were selected to provide theoretical knowledge for speech therapists regarding tinnitus management ( Fig. 1 ). All the content of the Portal do Zumbido was developed and was available for download and printing. The portal is comprised of the following modules:

Fig. 1.

Homepage of Portal do Zumbido .

• 1. Tinnitus:

In addition, didactic material for download and printing, entitled “Manual do Zumbido” (access module “Counseling”), was available.

For viewing in PDF and downloading the contents of all modules, access zumbido.fob.usp.br.

Assessment of the Portal do Zumbido

• 1. Subjects

Speech therapists working in the five regions of the country were invited to participate in the present study. Access to the platform was proposed with theoretical content on tinnitus management (tele-education) through Portal do Zumbido , available at the zumbido.fob.usp.br electronic address.

The contact was conducted by e-mail, in which the professionals were guided and informed about the objectives of the present study.

Professionals were guided to register at Portal do Zumbido informing their personal data (name, e-mail, ID, registration number in the Federal Council of Speech Therapy, region of work, and academic level). All participants were informed regarding the purpose and procedures of the study and the need to agree to the informed consent form that was available online and for download.

• 2. Questionnaire about the theoretical content

The professionals were guided to access the portal and, at the end, to answer an online form (Appendix A) in the module “assessment.” This form was prepared using the Google Forms tool, and it was composed of 10 questions regarding the content of Portal do Zumbido . Each question had three answer options, out of which only one was correct. If the participant hit the correct answer, he or she got 1 point and, if the participant failed, he or she did not score. At the end of the questionnaire, the professionals received feedback on their performance.

The e-mail portalzumbido@gmail.com was available to answer the questions of the participants.

• 3. Motivational Research Sheet (MRS)

After accessing the modules, the MRS was used for the assessment of motivational aspects related to Portal do Zumbido . ^{10 18} The MRS is composed of 32 statements. Numerically, each statement is punctuated as follows: (3) completely agree, (2) partially agree, (1) partially disagree, and (0) completely disagree.

The MRS statements are grouped into four domains: “stimulant,” “significant,” “organized,” and “easy to use.” The domain “stimulant” is grouped by statements 1, 5, 9, 13, 17, 21, 25 and 29. The domain “significant” by statements 2, 6, 10, 14, 18, 22, 26 and 30. The domain “organized” by statements 3, 7, 11, 15, 19, 23, 27 and 31. The “easy to use” domain by statements 4, 8, 12, 16, 20, 24, 28 and 32.

After scoring each domain individually, they are grouped according to the formula: V = E + S; XS = O + F. The V score is the sum of the domains “stimulant” and “significant” and reflects the value dimension, that is, how valuable this distance-learning-course is. The XS score is the sum of the “organized” and “easy to use” domains and reflects the expectation dimension for success. To finalize the score, the WebMAC authors recommended the use of a Cartesian projection. The abscissa (X-axis) is the score corresponding to the value dimension, and the ordinate (Y-axis) is the score corresponding to the expectation dimension for success. If the points or a large number of individual points are located within the area (impressive course!), it means that the distance-learning-course is an “impressive course,” evaluating it positively. ¹⁸

Data Analysis

The data collected through the questionnaires were transferred to a Microsoft Excel (Microsoft Corp., Redmond, WA, USA) spreadsheet and analyzed through quantitative and qualitative descriptive statistics.

Results

Speech therapists who worked in five regions of the country were invited to participate in the present study. Forty-six professionals ( Fig. 2 ) registered but only 38 answered the entire questionnaire ( Fig. 3 ).

Discussion

Tinnitus is considered a public health issue due to its prevalence and all the negative changes that may be associated with it. As such, studies have been developed to help the professionals in the assistance of this population. ^{19 20} Therefore, the present study used tele-education to provide information based on scientific evidence for speech therapists.

Speech therapists of three different regions of Brazil participated in the present study ( Fig. 3 ), which characterized the internet and the advanced technology as facilitating resources for the transmission of information. ²¹ The region with the highest number of professionals participating in the present study was the Southeast. This result can be explained when analyzing the speech therapists' division in Brazil, which presents a high concentration of these professionals in the Southeast region, of which 12,577 are in the state of São Paulo. ²² Thus, the Speech Therapy Program of Faculdade de Odontologia de Bauru - Universidade de São Paulo is considered the pioneer in the creation and development of educational tools using tele-education in audiology as well as offering great support to studies that involve technology in the teaching-learning process. ^{23 24}

Professionals with different academic levels accessed the modules of Portal do Zumbido and evaluated it, corroborating with the affirmation that the programs of telehealth can establish an important alternative of promotion of the continuous professional updating, thus, it can help on the reduction of educational deficits in Brazil ( Fig. 4 ). ^{18 23 24 25}

The entire content of Portal doZumbido was developed with the support of a professional designer; thus, it was possible to transmit the necessary information in a less exhaustive way, with the use of infographics. ¹⁷

The Portal do Zumbido was divided into modules. The first module is characterized by the introduction to tinnitus. In this module, important concepts regarding the symptom (classification, cure), scientific articles dealing with the topic, and specific books of audiology were used, as well as other studies that also had as an objective the development of virtual platforms of information. ^{9 12 13 24}

The second module, “audiological diagnosis,” contemplates the main procedures performed for the assessment of hearing and to detect the presence or absence of hearing loss. ²⁶ The importance of developing a module on this topic is due to the fact that tinnitus occurs as an isolated idiopathic symptom or related to any type of hearing loss. ²⁷ Tinnitus can cause physiological changes throughout the entire auditory pathway. In more than 50% of the cases, the symptom is a consequence of early cochlear lesions, such as sudden hearing loss, noise-induced acoustic trauma, presbiacusis or use of ototoxic drugs. ²⁸ Therefore, it is extremely important to perform the evaluation of auditory functions.

In addition, there are exams that early detect the hearing loss, since they evaluate an extended range of frequencies, which is not evaluated in conventional audiometry. Thus, the module “Complementary examinations,” provides information regarding tinnitus and hearing loss to guide professionals that attend this population. ^{26 29}

One of the main reasons that encouraged the development of the present study was to address the intervention of patients with tinnitus. The following three modules, entitled “Fitting of hearing aids,” “Fitting of Sound Generator” and “Counseling” address the main treatments that the speech therapist can offer to the subject with tinnitus, in view of the habituation and remission of the symptom. ^{4 30 31 32 33} Therefore, questionnaires (THI, HHIA, HHIE) that help the speech therapists to understand both hearing loss and tinnitus have been available in these modules for download and printing. ³⁴ Providing scientific information about a specific content in audiology and providing resources for download and printing were also used by other researchers who developed virtual platforms. ^{9 18 24}

Concerning tinnitus subjects, the speech therapist should offer individualized care. Thus, during the whole process, from diagnosis to treatment, the speech therapist may find situations that compete with other professionals. In this sense, the module “Leading” discusses this topic. Therefore, studies reported the prevalence of 28% to 76% of tinnitus in subjects with temporomandibular disorders (TMD), in addition, it can be associated with changes of several etiologies, requiring the performance of professionals with different specialties to provide global care for the necessity of the subject. ^{35 36 37}

The last module, “Assessment,” was composed of the MRS and forms approaches for theoretical content. The results were satisfactory for the 10 questions, demonstrating that the content presented by the Portal do Zumbido was positively absorbed by the participants ( Fig. 4 ). These positive results corroborate with other studies that have analyzed the theoretical content. ^{24 38}

Question 7, with the lowest hit rate (“ Why to perform the self-reported questionnaires? ”), presented 9.3% of incorrect answers since it can be justified by the fact that there is no standardization and consensus on the assessment methods of tinnitus due to its complexity, thus, not all professionals use self-assessment questionnaires in the clinical routine. ^{4 28 39}

In relation to the analysis of the motivational aspects of the portal through the MRS, ^{18 24 25} it was possible to observe high satisfaction with the Portal do Zumbido since the participating professionals considered it impressive. ⁴⁰ The same was observed in the other study, which aim was to develop and analyze the effectiveness of a Hearing Health Training Program (Hearing aids) through interactive tele-education. ¹³

Regarding the four domains analyzed (“organized,” “easy to use,” “stimulating” and “significant”), the scores varied from 22.8, 22.4, 22.5 and 22.2 ( Table 1 ), as a previous study that developed the FM System Portal and used the MRS with results that varied from 22.52, 22.32, 21.97 and 21.45. ²⁴

Therefore, it is important to reflect on the facilities promoted by telehealth, as well as its assistance in the continuing education of speech therapists, thus it is suggested that the Portal do Zumbido be continually updated due to the need to provide current scientific information to professionals working with this population.

Conclusions

A virtual platform on tinnitus management in portal format was developed.

The Portal do Zumbido is available at zumbido.fob.usp.br.

The motivation of the participating professionals regarding Portal do Zumbido was satisfactory, and it was classified as impressive.

Access to the modules of Portal do Zumbido allowed the participants to absorb the proposed content.
