To gauge the prevalence of hearing loss in school children in Bishkek, Kyrgyzstan, and refer pupils with positive results for further diagnostic testing.
Background:
According to WHO data, hearing disorders are common in school-age children. Screening for hearing loss is an important preventative tool, helping to avoid further complications. Expenditure that supports early child development can reduce future outlay on health care and social services; it can eliminate disability problems, education deficits, and social maladaptation in later adult life.
Methods:
Pure-tone air-conduction hearing thresholds were obtained at 0.5–8 kHz. The results of the hearing screening examination were regarded as positive if pure-tone thresholds were higher than 20 dB HL in one or both ears at one or more of the test frequencies. Data were also obtained from follow-up visits of children who failed the initial screening.
Findings:
This study included 452 children aged 7–13 years old. Based on audiograms, screening showed that 123 (27.2%) of the children had hearing impairment. The study has important implications for clinical practice and health policy. There is a need for systematic monitoring of hearing status among children of this age, and parents and educators need to be made aware of the significance of hearing loss.
Hearing loss is highly prevalent in older adults and can pose challenges for neuropsychologists, as assessment and intervention procedures often involve orally presented information which must be accurately heard. This project examined the hearing status of 20 clients (mean age = 71 years) in a hospital-based outpatient neuropsychology clinic, and explored whether information about hearing loss informed neuropsychologists’ clinical practice. A research assistant administered a brief hearing screening test to each participant. Four treating neuropsychologists were asked to comment on their client’s hearing status before and after being shown their client’s hearing screen test results. Screening revealed that the majority of participants had at least mild hearing loss, and that the neuropsychologists were relatively accurate (60%) at estimating their clients’ hearing status. Neuropsychologists used information about a client’s hearing status to make recommendations that clients pursue audiologic services, and to educate clients and family members about hearing loss and communication.
Millions of people across the world suffer from disabling hearing loss. Appropriate interventions lead to improved speech and language skills, educational advancement, and improved social integration. A major limitation to improving care is identifying those with disabling hearing loss in low-resource countries.
Objectives
This review article summarises information on currently available hearing screening platforms and technology available from published reports and the authors’ personal experiences of hearing loss identification in low-resource areas of the world. The paper reviews the scope and capabilities of portable hearing screening platforms, including the pros and cons of each technology and how they have been utilised in low-resource environments.
Conclusion
Portable hearing screening tools are readily available to assess hearing loss in low-resource areas. Each technology has advantages and limitations that should be considered when identifying the optimal methods to assess needs in each country.
