Определение и качество скрининга
• Основной целью скрининга является первичная идентификация заболеваний и расстройств, которые не выявляются другими способами, с помощью соответствующих методов. Скрининг позволяет выделить из всего населения группы повышенного риска.

Определение и качество скрининга
• Чувствительность, специфичность и простота в использовании (минимизация перенаправлений)
• Неопределяемость нарушения через клинические исследования
• Доступность методов вмешательства с целью коррекции проблем, определенных скринингом.
• Ранний скрининг, диангостика и вмешательство способствуют улучшению результатов.
• Приемлемая стоимость.

Определение и качество скрининга
• Глухота – наиболее частое расстройство у новорожденных.
• Скрининг на предмет врожденной потери слуха является неинвазивным, объективным и недорогим.
• Доступно оборудование для измерения ОАЭ и АРСП.
• Ведущие производители утверждают, что чувствительность их оборудования достигает 99%, а специфичность – 97%.
Неонатальный скрининг отвечает всем критериям

Overview of the Worldwide Situation
USA:
90% of newborns screened
Germany:
Law passed in 2009, responsibility lies with federal lands
Loss to follow-up varies within 2 to 50%.
The situation is very heterogeneous

Facts
- the incidence of hearing loss in very young children is high
- suitable screening equipment is available
Still, the necessity of hearing screening for children in pre-school age is unfortunately not yet discussed on a broad basis

Facts
Reputable audiologists and companies emphasize the importance of repeated hearing screenings at junctures in life, e.g. before school entry

Screening for the elderly
- There is a growing ageing population in developed countries
- The hearing loss in elderly people may be progressive, thus they accommodate to it and do not notice it
- Once the elderly person retires from social life due to deafness, it is almost too late for hearing aids to be effective
Also a growing necessity

Motivate the elderly to maintain their hearing
People in the „third quarter of their life” stay more active and feel younger, as long as they live self-sufficiently
Interaction with their environment and participation in social life is fundamental for self-esteem and well-being
Hearing and understanding are fundamental to ,,social competence"
