Effects of policy changes to universal newborn hearing screening follow-up in a university clinic
Insights
Policy changes improved infant hearing screening by reducing loss to follow-up and enabling earlier diagnosis. However, challenges remain in timely amplification and intervention initiation for infants with hearing loss.
Area of Science:
- Pediatric Audiology
- Public Health Policy
- Early Intervention Services
Background:
- Infant hearing screening is crucial for early detection and intervention of hearing loss.
- Established guidelines recommend diagnosis by 3 months, amplification by 4 months, and intervention by 6 months.
Purpose of the Study:
- To assess the impact of policy modifications on infant hearing screening outcomes.
- To evaluate changes in loss to follow-up rates and adherence to American Academy of Pediatrics guidelines.
Main Methods:
- Retrospective review of 111 infants' records.
- Extraction of data including demographics, diagnostic timelines, and intervention start dates.
- Comparison with pre-policy change data.
Main Results:
- Policy changes significantly decreased loss to follow-up rates.
- Earlier diagnosis of hearing loss was observed post-policy changes.
- While amplification occurred at younger ages, the 1-month target post-diagnosis was not consistently met.
Conclusions:
- Policy changes positively influenced follow-up and diagnosis timelines.
- Achieving timely amplification and documenting early intervention remain areas for improvement.
- Enhanced communication and education among stakeholders are essential for optimal infant hearing care.
Purpose:
The purpose of this study was to evaluate the effects of policy changes on loss to follow-up rates and the ability to achieve the goals of the American Academy of Pediatrics Joint Committee on Infant Hearing Screening (2007) for diagnosis of hearing loss by 3 months, amplification within 1 month of diagnosis, and start of intervention by 6 months.
Method:
From the files of 111 infants, data were extracted on the following: date of birth, birth hospital, hometown, parents' ages, ethnicity, nursery status, medical history, age at initial evaluation and diagnosis, results of evaluation(s), and age at hearing aid fitting and start of early intervention. Data were compared with previously published data from the clinic (Krishnan, 2009).
Results:
Policy changes led to a decrease in loss to follow-up and a younger age at diagnosis of hearing loss. Infants identified with hearing loss were fit with amplification at younger ages but not within 1 month of diagnosis of hearing loss. Policy changes had positive outcomes on loss to follow-up and age of diagnosis and amplification.
Conclusions:
Challenges remain in meeting the goals of amplification within 1 month of diagnosis and documenting the start of early intervention. Improved communication between and education of all parties involved in the care of infants is needed.
