[Newborn hearing screening - importance, current state in the Czech Republic]

Area of Science:

• Pediatrics
• Audiology
• Public Health

Background:

• Early detection and rehabilitation of hearing impairment in newborns and children are critical.
• Congenital hearing impairment incidence was underestimated, with actual rates significantly higher than the previously estimated 1:1000 neonates.
• Hearing loss affects 1 in 300 newborns profoundly and 1 in 300 mildly to moderately, with additional cases developing before age 18.

Purpose of the Study:

• To highlight the importance of newborn hearing screening and early intervention.
• To discuss the historical context and organizational aspects of hearing screening programs.
• To address challenges in implementing systematic newborn hearing screening and suggest practical solutions.

Main Methods:

• Review of existing literature on the importance of early hearing detection and rehabilitation.
• Analysis of the current status of newborn hearing screening in the Czech Republic, identifying regional disparities.
• Description of a multi-stage screening process (maternity hospitals, specialized workplaces, diagnostic centers).

Main Results:

• Newborn hearing screening has uncovered a 3x higher incidence of congenital hearing impairment than previously estimated.
• Systematic, multi-level newborn hearing screening is only conducted in three Czech regions, with data missing elsewhere.
• Effective screening requires a coordinated, multi-stage approach and robust statistical tracking at all levels.

Conclusions:

• Implementing comprehensive newborn hearing screening is essential for early intervention and improved outcomes.
• Standardized organization and data collection across all regions are necessary for effective national hearing loss surveillance.
• Establishing screening coordinators and ensuring statistical evidence are key to successful long-term implementation.
