Abstract: |
Background:
The Massachusetts (MA) Universal Newborn Hearing Screening Program (UNHSP) screens more than 99% of MA infants for hearing loss. The follow-up rate of audiologic diagnostic services (ADS) is 90-92% for infants who fail their Newborn Hearing Screen (NHS). A previous MA study demonstrated that ADS loss to follow-up varies significantly by geographic location of residence. The purpose of this analysis is to identify geographic risk factors for ADS loss to follow-up among MA children.
Methods:
Data from the MA Childhood Hearing Data System were used to determine the percentage of MA births during 2006 that failed a NHS and the percentage that were lost to ADS follow-up. These infants were further classified into general geographic location of residence. In the next phase of our analysis, every child who failed a NHS will be mapped by geographic location of residence. ArcGIS analysis will be conducted, focusing on clusters of loss to follow-up as identified by SaTScan statistical techniques. Factors including maternal demographics, neighborhood income, distance to diagnostic centers, and accessibility of roads and public transportation will be analyzed. Service delivery buffers will also be included, thus accounting for the capacity of the nearest audiologic service center.
Results:
In 2006, among the 1,299 (1.7%) infants who failed their NHS, 7.3% were lost to ADS follow-up. Lost to follow-up rates varied depending on general geographic location of residence. The Boston Region experienced the highest loss to follow-up rate of 11.4%, followed by the Northeastern and Southeastern MA Regions at 7.6% and 7.2%, respectively. The detailed geographic analysis is in progress.
Conclusions:
Children residing in the Boston Region, Northeastern and Southeastern MA are more likely to be lost to ADS follow-up than other MA residents. Our geographic analysis will provide more specific information regarding barriers to timely and appropriate follow-up. |
