Universal newborn hearing screening--the Colorado story

Area of Science:

• Public Health
• Audiology
• Pediatrics

Background:

• Universal newborn hearing screening programs are crucial for early detection of hearing loss.
• Early intervention significantly impacts long-term developmental outcomes in children.
• Colorado initiated a statewide program in 1992 to address this public health need.

Purpose of the Study:

• To report on the initial phase of Colorado's universal newborn hearing screening program.
• To assess the prevalence of hearing loss in newborns within the state.
• To evaluate the cost-effectiveness and impact of early intervention.

Main Methods:

• Screening of 14,494 infants across Colorado.
• Analysis of screening test results to identify infants who failed.
• Confirmation of hearing loss in a subset of infants who failed screening.

Main Results:

• 95% of infants passed initial hearing screening tests.
• 5% of infants failed the screening, requiring further evaluation.
• 6% of infants who failed screening were confirmed to have hearing loss, with an average screening cost of $25.00 per infant.

Conclusions:

• The Colorado universal newborn hearing screening program identified a significant number of infants with hearing loss.
• Early identification and intervention, by 3 months, lead to better outcomes at 40 months.
• The program demonstrates the feasibility and importance of statewide newborn hearing screening.
