Objective:
To explore risk factors for non-participation for the Danish universal newborn hearing screening program, including socioeconomic demographic and peripartum conditions. Furthermore, the participation rate between children with medical risk factors for congenital hearing loss and healthy newborns was analyzed.
Methods:
The study was register-based and included all live births in Denmark between January 1st, 2008 and December 31st, 2011, in total 251,081 children. Potential risk factors were extracted from eight Danish national registers and analyzed via logistic regression models.
Results:
With respect to the participation rate, the strongest predictors of non-participation were increased maternal parity (from OR: 0.85; 95% CI: 0.82-0.89; p<0.0001 to OR: 0.43; 95% CI: 0.38-0.47; P<0.0001), low socio-economic status, including income, (from OR: 1.16; 95% CI: 1.09-1.23; p<0.0001 to OR: 1.46; 95% CI: 1.37-1.56; p<0.0001) and home birth (OR: 0.58; 95% CI: 0.42-0.80; p=0.001). Children with a medical risk factor for congenital hearing loss had a 1.97% lower participation rate. Assisted ventilation and admission to a newborn intensive care unit for > 48 hours were identified as independent risk factors of non-participation for this group (OR: 0.65; 95% CI: 0.52-0.80; p<0.0001 and OR: 0.92; 95% CI: 0.85-0.99; p=0.036, respectively).
Conclusion:
In order to improve the participation rate, a national screening database in conjunction with a stronger collaboration between screening units and other health care professionals who are in contact with the family during the newborn period is warranted.
