摘要：IntroductionPermanent hearing loss (PHL) in childhood can profoundly impact development, with high economic costs to children and society. Hearing technology and service delivery advances, including universal newborn hearing screening implemented in Ontario in 2002 as part of the Infant Hearing Program (IHP), aim to improve outcomes of children with PHL. Objectives and ApproachWe examined the impact of IHP screening on age of identification of PHL, and compared healthcare utilization in children with and without PHL, in the Census Metropolitan Area of Ottawa. Children with PHL, identified from a database at the Children’s Hospital of Eastern Ontario, were linked to health administrative data housed at the Institute for Clinical Evaluative Sciences. Five residents of Ottawa acted as non-PHL controls for each PHL case. A regression discontinuity design (RDD) was used to investigate differences in age of identification pre- and post-IHP implementation. Poisson regression will compare healthcare utilization among children with and without PHL. ResultsReceipt of the HBPB was associated with reductions in low birth weight births (adjusted Relative Risk (aRR): 0.77; 95% CI: 0.63, 0.93) and preterm births (aRR: 0.78 (0.68, 0.90)), and increases in breastfeeding initiation (aRR: 1.05 (1.00, 1.09)) and large-for-gestational age births (aRR: 1.11 (1.01, 1.23)). HBPB receipt during pregnancy was also associated with increases in 1- and 2-year immunizations for FN children (aRR: 1.14 (1.09, 1.19), and aRR: 1.28 (1.19, 1.36), respectively). Reductions in the risk of being developmentally vulnerable in the language and cognitive domain of the EDI were also found for FN children whose mothers had received the HBPB during pregnancy (aRR: 0.85 (0.74, 0.97). Conclusion/ImplicationsIHP implementation resulted in earlier identificationof PHL in children, allowing earlier access to audiologic and habilitative services. However, children with PHL used the health system more often and in different ways from those without PHL. These results can support improvements in service delivery for children with PHL.
