Audiology and hearing health professionals in Brazil

Last updated

Despite having the largest economy in South America or Central America, Brazil is still considered a developing country due to its low gross domestic product, or GDP, per capita, low living standards, high infant mortality rate and other factors. "With regard to hearing health, the Brazilian government established the national policy for giving attention to hearing health in 2004, in which the Ministry of Health, considering the social magnitude of hearing impairment in the Brazilian population and its consequences, presented the proposal to structure a network of services set up by regions and in hierarchy that aims to be implemented in all federative units of Brazil, with integrated actions to promote ear health, hearing impairment prevention, treatment and rehabilitation organized and managed by the National Health System, Sistema Único de Saúde (SUS), in Portuguese," writes Bevilacqua et al. (2010) [1]

In Brazil, audiology grew out of the field of ear nose and throat (ENT) medical field. According to Bevilacqua et al. (2008), [2] the majority of audiologists in Brazil work at private institutions, including private medical practices and dedicated speech and hearing clinics. They are also employed in public institutions, such as community clinics, elementary schools, colleges, and universities. Audiologists perform diagnostic evaluations of auditory and vestibular disorders, select and fit hearing aids, and provide aural rehabilitation. They may also assist with workers’ health programs, dispense hearing aids, and aural rehabilitation in the public sector.

Hearing healthcare professional qualifications

According to Bevilacqua et al. (2008), [2] "the entry level for the profession remains the baccalaureate degree. The undergraduate course in fonoaudiologia involves a double major with coursework in both speech-language pathology and audiology. Classes include the basic sciences, anatomy and physiology, human development, linguistics, phonetics, psychology, the nature and process of audition and balance, normal and abnormal communication development, and supervised clinical practicum. A double license is granted to graduates of this four-year course, and they are free to work in any area of the field. Graduates must also comply with federal regulatory (licensure) standards in order to practice". According to the Brazilian Federal Speech Language Pathology and Audiology Council (Conselho Federal de Fonoaudiologia, 2018 [3] ), there are currently 117 undergraduate courses in speech-language pathology and audiology in Brazil, with approximately 44.000 professionals in all country. It is at graduate level that different courses are offered in the four areas of specialization defined by the Speech-Language Pathology and Audiology Council (audiology, language, oral motor disorders, and voice). There are several options for degrees and coursework. Some courses offer a 500-hour course of study which provides advanced clinical training focused in one of the four areas of specialization, and graduates receive the title ‘Specialist’. In addition, a few universities offer masters and doctoral degree courses designed to provide the necessary training for those aiming at a career in research and education. Currently, there are 32 specialization courses and eight graduate courses in communication disorders throughout Brazil."

Universal newborn hearing screening

Brazil is one of the few developing countries that provides universal newborn hearing screenings. Brazil has one of the largest and oldest newborn hearing screening programs (NHSP) in Latin America with over 246 screening sites across 24 of the 27 Brazilian states. According to Cavalcanti & Guerra (2012), [4] the first NHSP dates back to 1988 in São Paulo. Originally, only babies with risk factors were screened for hearing loss. Despite efforts being made to implement newborn hearing screening throughout Brazil, 77% of the UNHS programs are in the Southern, which is the more industrialized part of the country. In 2004, Brazil established a national policy for hearing health which included diagnostic procedures, hearing aids and cochlear implants being provided to the pediatric population free of charge and rehabilitation services available for infants identified with hearing loss at an early age. Newborn hearing screening is one of the leading contributors for engaging subsequent diagnostic, treatment and rehabilitation actions. One example of a universal newborn hearing screenings are at the Public Hospital of Bauru, Sa˜o Paulo state, Brazil. The screening method this location uses is a two-stage screening consisting of transient otoacoustic emissions (TOAE), performed by an audiologist. If the newborn does not pass the first part of the screening then they are referred to Audiology and Speech Pathology Clinic at the University of São Paulo, campus of Bauru for diagnostic follow-up testing and intervention. Bevilacqua et al., (2010) [1] reviewed the average cost of the newborn hearing screening in Brazil and found the cost of hearing screening was equivalent to US$7.00 and the annual cost of the universal newborn hearing screening program was equivalent to US$26,940.47.

<span class="mw-page-title-main">Audiology</span> Branch of science that studies hearing, balance, and related disorders

Audiology is a branch of science that studies hearing, balance, and related disorders. Audiologists treat those with hearing loss and proactively prevent related damage. By employing various testing strategies, audiologists aim to determine whether someone has normal sensitivity to sounds. If hearing loss is identified, audiologists determine which portions of hearing are affected, to what degree, and where the lesion causing the hearing loss is found. If an audiologist determines that a hearing loss or vestibular abnormality is present, they will provide recommendations for interventions or rehabilitation.

Auditory neuropathy (AN) is a hearing disorder in which the outer hair cells of the cochlea are present and functional, but sound information is not transmitted sufficiently by the auditory nerve to the brain. The cause may be several dysfunctions of the inner hair cells of the cochlea or spiral ganglion neuron levels. Hearing loss with AN can range from normal hearing sensitivity to profound hearing loss.

The Doctor of Audiology is a professional degree for an audiologist. The AuD program is designed to produce audiologists who are skilled in providing diagnostic, rehabilitative, and other services associated with hearing, balance, tinnitus management, and related audiological fields. These individuals help patients with hearing problems primarily by diagnosing hearing loss and fitting hearing assistive devices.

An Audiometrist or Audiometric Officer, is a health-care professional technician who has received special training in the use of Pure tone audiometry equipment. An audiometrist conducts hearing tests, or "audiometric screening", with an Audiometer to establish hearing levels. The results are represented by an audiogram, and are usually interpreted by an audiologist, or a registered Medical Officer, unless the audiometrist is also an audiologist, with the aim of diagnosing hearing loss.

Sound Seekers was a British charity which works to improve the lives of deaf children and children with ear diseases in the developing countries of the Commonwealth of Nations. It provided specialist equipment, training and support to some of the poorest countries of the world, where people with the 'hidden disability' of deafness may otherwise not receive the help they need. In 2020, Sound Seekers merged with DeafKidz International, with the combined charity using the DeafKidz International name.

Auditory processing disorder (APD), rarely known as King-Kopetzky syndrome or auditory disability with normal hearing (ADN), is a neurodevelopmental disorder affecting the way the brain processes sounds. Individuals with APD usually have normal structure and function of the ear, but cannot process the information they hear in the same way as others do, which leads to difficulties in recognizing and interpreting sounds, especially the sounds composing speech. It is thought that these difficulties arise from dysfunction in the central nervous system. This is, in part, essentially a failure of the cocktail party effect found in most people.

Aural rehabilitation is the process of identifying and diagnosing a hearing loss, providing different types of therapies to clients who are hard of hearing, and implementing different amplification devices to aid the client's hearing abilities. Aural rehab includes specific procedures in which each therapy and amplification device has as its goal the habilitation or rehabilitation of persons to overcome the handicap (disability) caused by a hearing impairment or deafness.

Marion Downs was an American audiologist and Professor Emerita at the University of Colorado Health Sciences Center, Denver, who pioneered universal newborn hearing screening in the early 1960s, then spent more than 30 years trying to convince her peers to adopt the testing in hospitals and to place hearing aids on infants who showed hearing loss. She worked to alert the medical world to the developmental problems associated with childhood deafness. As a result of her efforts, 95 percent of all newborns in America today are screened for hearing loss. She devoted her professional life to the promotion of early identification of hearing loss in newborns, infants, and young children and to helping deaf and hard of hearing individuals lead fulfilling lives.

<span class="mw-page-title-main">Universal neonatal hearing screening</span> Policy of routinely testing the hearing of babies soon after birth

Universal neonatal hearing screening (UNHS), which is part of early hearing detection and intervention (EHDI) programmes, refer to those services aimed at screening hearing of all newborns, regardless of the presence of a risk factor for hearing loss. UNHS is the first step in the EHDI program which indicates whether a newborn requires further audiological assessment to determine the presence or absence of permanent hearing loss. Newborn hearing screening uses objective testing methods to screen the hearing of all newborns in a particular target region, regardless of the presence or absence of risk factors. Even among developed countries, until the 1990s, it could take years for hearing-impaired child to be diagnosed and to benefit from a health intervention and amplification. This delay still can happen in developing countries. If children are not exposed to sounds and language during their first years of life because of a hearing loss, they will have difficulty in developing spoken or signed language; cognitive development and social skills could also be affected. This screening separates children into two groups—those with a high index of suspicion and those with a low index of suspicion. Those in the first group are referred for diagnostic testing.
